Liu Yunzi said, "I didn't expect that among my disciples, you are the richest. But this is a gift from your master, so please accept it." Shi Feng had no choice but to thank him and accept the bag of crystals.
Liu Yunzi asked again, "What is the name of your body cultivation technique?" Shi Feng was stunned for a moment. Although he didn't want to deceive Liu Yunzi, Dao Chong had said that the origin of the nameless body cultivation technique was unknown and it was forbidden to be disclosed to anyone. He could only say, "It's a book of Vajra Sutra that I found in the Sutra Library."
The Vajra Sutra is a body-refining technique included in the third level of the Sutra Library. No one in the entire Tai Chi Sect practices it. After achieving a certain level of success in this body-refining technique, the body surface will turn golden and become invulnerable to swords and spears. It is 70% similar to this unnamed body-refining technique.
Liu Yunzi obviously didn't understand the body-building technique either, so he nodded and said, "From the name, it seems to be a Buddhist technique. We Taoists rarely have body-building techniques, and this technique must have been obtained from somewhere by the elders of the sect. And the archery technique is the magical power of this Vajra Sutra, right?"
In fact, the nameless body-refining technique did not record any magical powers at all. Archery was just a hunting skill that Shi Feng had learned since he was a child. Shi Feng could not explain it, so when he heard Liu Yunzi think so, he naturally nodded in agreement.
Liu Yunzi took out a jade box from his storage bag and handed it to Shi Feng, saying, "You've earned honor for your master this time, so this piece of water copper stone is a reward for you. I think the iron bow you forged is quite good, so you should see if this water copper stone is useful. If not, sell it. This water copper stone is also a very precious refining material. Don't agree to anything less than 5,000 spirit stones."
Shi Feng was overjoyed. This hydro-copperstone was an excellent material. Iron essence, due to its hardness, needed to be mixed with a flexible metal, and copper essence was the best choice. However, copper essence was far rarer than iron essence. Hydro-copper essence, mined from the deep sea, was flexible and much lighter than ordinary copper essence. However, the fusion process was much more difficult than with ordinary copper essence. Shi Feng thanked him profusely and hurriedly accepted the copper essence.
Liu Yunzi saw Shi Feng take the jade box and simply put it in his pocket instead of putting it away. Then he remembered that Shi Feng was not a Qi Refiner and had no mana, so he couldn't operate the storage bag. He immediately took out another item, a three-foot-long tiger-head buckle belt, and said, "Shi Feng, as the saying goes, wealth should not be displayed. You have quite a few spiritual stones and materials on you. Carrying them in your pocket all day will bring you unexpected disasters. I bought this belt from a local refining pavilion when I was traveling in the West decades ago. The customs there are completely different from our Zhongtian Continent, and there are many strange and unique items."
Shi Feng took the buckle and saw that it seemed to be made of cowhide. The buckle head and the buckle tail were both cast iron. The buckle head was carved with a black tiger head with four sharp teeth exposed, and the buckle tail was a section of a tiger claw, and the two could be buckled together perfectly.
Liu Yunzi said, "This is a storage bag commonly used by some local body-refining sects. A soil spirit stone must be placed in the groove of the buckle to activate it. There is about ten square meters of space inside the buckle, which can hold a lot of things. I saw it at the time and felt curious, so I bought one. The advantage of this storage buckle is that it does not require mana, you only need to place spirit stones, and you can put things in and take them out at any time. Moreover, the weight of the things put in can be ignored, so it is very convenient to carry." As he spoke, he explained to Shi Feng in detail how to use the tiger-head buckle.
Shi Feng followed his instructions and put the buckle around his waist. He took out an earth spirit stone and put it into his tiger's mouth. The buckle emitted a yellow light, which then disappeared. It was still an ordinary belt.
Shi Feng picked up the bag of crystals and chanted a spell. Suddenly, the bag disappeared from his hand. Then, he used his spiritual sense to scan it. The bag of crystals was already in the small space in the buckle. Shi Feng moved his mind again, chanted a spell, and the bag of crystals was in his hand again.
Shi Feng had always worried about not having a storage bag. This three-ring tiger belt had enough space to store all his belongings. He said happily, "Thank you, Master, for this generous gift."
Liu Yunzi said, "What a generous gift this is! You must remember that living things cannot be put into this storage buckle, and unlike the storage bags used by cultivators, it cannot be set with restrictions. Once the belt is snatched away by someone else, the things will naturally belong to someone else. In addition, although this type of storage buckle ignores the weight of the items, it is of a lower level after all. Excessively heavy items may cause the storage space to collapse." Shi Feng nodded repeatedly.
Liu Yunzi chuckled, "Also, your master will teach you a magical skill." Shi He was stunned. "My disciple has no spiritual roots and no spiritual energy in his body. What magical skill can I practice?" Liu Yunzi said, "The first part of what you said is correct, but the second part is wrong. Your innate constitution does not have spiritual roots, but it does not mean that your body is without spiritual power. Having spiritual roots means that you can breathe in and out the spiritual energy of heaven and earth and transfer it into the sea of qi in your dantian. This is internal cultivation. Those who practice physical cultivation also breathe in the spiritual energy of heaven and earth, but they strengthen their skin, muscles, and bones. This is external cultivation. You have been practicing physical cultivation for three years. Although there is no spiritual power in your dantian, your muscles and bones do have spiritual energy. Otherwise, how could you shoot down the Thousand Shadow Ring with brute force?"
Shi Feng suddenly realized that after practicing the nameless body-refining technique, he thought that his strength had increased a lot. He could shoot a hundred steps before, but now he could easily reach three to five hundred steps. Now he realized that his body also contained spiritual power.
Liu Yunzi sighed and said, "However, for those who practice physical cultivation, spiritual energy is only stored in muscles and bones. Physical strength and spiritual energy are consumed at the same time. They cannot breathe, so they cannot increase their lifespan. Ultimately, they are no match for those who practice internal cultivation." After saying that, he flipped his hand, and a jade slip appeared in his palm. With a casual tap of his hand, a ray of light flew out of the jade slip and rushed into Shi Feng's mind.
Shi Feng's spiritual sense swept over it, revealing a thin book. Liu Yunzi said, "This magical power is called Boomerang, and it's a metal-based magical power. Originally, the first half of it was a cultivation method, but I think you don't have spiritual roots, so you don't need to cultivate the cultivation method. You can just learn the magical power directly." Shi Feng murmured, "Boomerang? Is it a hidden weapon?"
Liu Yunzi nodded and suddenly asked, "Shi Feng, do you know why you lost to Liu Suifeng from Diecui Peak in the third round?"
Shi Feng thought for a moment after hearing him suddenly ask about this, and said, "Senior Brother Liu has profound magical powers, and his thorn technique is unpredictable. I am no match for him." Liu Yunzi said, "No, the reason you lost is very simple. You ran out of arrows."
Shi Feng scratched his head, feeling a little confused.
Liu Yunzi said, "I secretly watched your competition. Although Liu Suifeng is ranked among the top ten in strength among the disciples in the Qi Refining Stage, he may not be able to defeat you. You have practiced the body refining technique very well, and your iron bow and iron arrows are very powerful. If you have countless feather arrows available, hehe, Liu Suifeng will have no time to use the thorn technique. Although his wooden shield has good defense, most of its power has been consumed at that time. If you shoot him a dozen more arrows, his shield will be broken. Without the shield, how can he avoid your lightning-fast arrows?" Shi Feng thought it made sense and nodded secretly.
Liu Yunzi said, "The magical power of the boomerang was passed down to me by the Danyang Patriarch, but I have never had the time to practice it. This boomerang is based on the gold-based skills of Tiejian Peak. First, the essence of the five metals is extracted, and then the internal true fire is used to refine a dart about three inches long. It is indeed used as a hidden weapon when facing the enemy." Shi Feng blinked his eyes. He was confused as he could not do anything with the gold-based skills or the internal true fire.
Liu Yunzi said, "You look dull, but you're actually incredibly meticulous. Why are you so rigid? Aren't your bows and arrows just concealed weapons? What's the difference between a three-inch long and a foot long? The most unique feature of this boomerang is its magical power. With clever use of force, it can spin in the air, change direction, and even fly back automatically. If you master this magical power, you can retrieve the arrows you shoot, which is like having an endless supply of arrows."
Shi Feng's eyes lit up and he said happily, "That's great. Disciple thanks Master!"
Shi Feng was still very excited when he returned to the Sword Casting Valley. Apart from the crystal stone that Liu Yunzi gave him today, the other three items, the tiger head buckle, the water copper stone, and the boomerang magic power, were extremely useful to him.
He first tried to use the tiger-head buckle several times before trying to put the iron dragon bow and other items in it. Shi Feng had collected a lot of refining materials in the past three years, some common and some rare, which had always been scattered on the floor of the room. Now he sorted them out one by one and put them into the buckle, and the whole room felt a lot fresher.
Then he took out the water copper stone and observed it carefully. There were seven copper-colored water patterns in the water copper stone. Although it was not the top-grade nine-pattern stone, its quality was also quite high. This was one of the most valuable refining materials that Shi Feng currently had, and its value was comparable to the Thousand Fire Embers.
After placing the water copper stone into the jade box and carefully putting it into the buckle, Shi Feng flipped through the book on boomerang magic. Sure enough, Liu Yunzi only recorded the method of using the boomerang, and there was no record of any skills.
After reading all night, Shi Feng only understood about 10% to 20% of it, but he kept in mind Liu Yunzi's words that one should be flexible and adaptable in everything and not stick to rigid rules.
In fact, he didn't know at this time that this sentence would have a huge impact on his future cultivation.
Classical literature states, "If the diameter of a dart is three inches and the force reaches seven zhang, three forces should be on the left, six forces on the right, and one force at the back. If the dart is moved slightly by half a foot, it should fly obliquely. If it kills the enemy within seven zhang, it will fly three zhang to the left and then return." This record is for darts, but Shi Feng used a bow and arrow, so of course he had to revise a series of data based on the length of his arrow.
In the following month, Shi Feng comprehended the boomerang magic every day, and corrected it one by one when applying it to bows and arrows. Every sentence had to be tested in practice to determine whether it was correct. Shi Feng renamed it the boomerang.
While comprehending the magical powers, Shi Feng was also preparing for a bigger thing, which was to recast the bow and arrow.
The Iron Dragon Bow was the first spiritual weapon that Shi Feng had forged personally, but he lacked confidence at that time and only chose a three-seal magic weapon to practice. Now that he has repaired more and more spiritual weapons for everyone, his knowledge has increased greatly and his confidence has become stronger, especially since Liu Yunzi gave him this water copper stone. He immediately thought of the refining book compiled by Zhenren Ganchu. There was a bow with nine restrictions, the "Cloud Piercing Bow", and one of the materials required was exactly water copper stone.
The Cloud Piercing Bow was a wind-attributed spiritual weapon, renowned for its high speed and long range. Four of the nine restrictions required to be engraved increased its speed. These nine restrictions were quite complex, but Shi Feng felt they were not too difficult. He immediately spent four thousand spirit stones on other auxiliary materials and began forging the Cloud Piercing Bow. His work was slow, but meticulous. It took him over twenty days to finally complete the Cloud Piercing Bow. Shi Feng tested it and found that not only was the range increased by half compared to his previous Iron Dragon Bow, but the speed of drawing the string and releasing arrows was also far superior.
Shi Feng was overjoyed and presented the bow and arrow to Gan Chu Zhenren. The old Taoist praised it highly, saying, "Although it's only a low-grade Nine Seals spiritual weapon, this bow is much more powerful than an average mid-grade spiritual weapon. You're a promising weapon refiner. If you want to sell this bow, don't sell it for less than 20,000 spirit stones." Shi Feng thought to himself, "The Thousand Fire Embers and the Water Copper Stone alone are worth at least 10,000 or 20,000 crystals. Why would I sell it for a mere 20,000 crystals?"
After the Cloud Piercing Bow was completed, Shi Feng tried to use it to shoot boomerang arrows. After two or three months, he gradually became more proficient in it. After the bow and arrow were shot, they could either be straight as a line, or fly diagonally in the middle, or curve like a rainbow. After the arrow was shot, the remaining force would continue to spin and fly back again.
One day, Shi Feng had a sudden thought: since he could do two things at once, why not control two arrows simultaneously? He immediately began experimenting. Initially, his movements were awkward: the two arrows either followed the same trajectory or had uneven force, dropping to the ground mid-flight. But with constant practice, his proficiency grew, and he gradually mastered the art of shooting and receiving arrows at will. However, shooting two arrows simultaneously didn't pack the same force as using just one.
