Mu Lao sighed and continued, "At my age, the Marrow Cleansing Pill is no longer effective. This pill is for Yan'er." "The little girl was ambushed not long ago and suffered a special kind of cold poison. Fortunately, I discovered it in time, but ordinary detoxification pills are useless against this poison. Coincidentally, the Marrow Cleansing Pill can expel this cold poison." "However, there are no Marrow Cleansing Pills for sale in Falling Star City recently, and Yan'er cannot afford to delay. I inquired everywhere and finally got the news, so I came here to find the main ingredient for the Marrow Cleansing Pill." "Hehe, I didn't expect to encounter these three evil men from Evil Wind Valley on the way and be besieged by them. If I hadn't met you, young friend, I would have ended up here today." Although Zhang Ling didn't completely believe Mu Lao's words, he was still a little worried when he heard that Yan'er was poisoned. Back then, Mu Lao's granddaughter, Yan'er, sold him the spirit herb illustrated book for ten spirit stones, which greatly helped him in cultivating spirit herbs and refining pills over the years. "Did you find the spirit herb?" "Although I encountered a few evil men, I successfully collected the spirit herb." The two chatted for a while, and Mu Lao invited him to return to Falling Star City together. Zhang Ling thought about it and agreed. Two days later, Zhang Ling returned to his cave. This trip lasted more than a month. Not only did his fighting experience increase a lot, but he also killed two cultivators. He also had a clear understanding of his own strength.
Although he suffered some injuries, he had already recovered. After returning to the cave, he slept for a day and a night, and didn't wake up refreshed until noon. At this moment, he was counting his gains from this trip. Three storage bags were placed on the stone table. These were the storage bags of the black-clothed man and the bearded man. The owners of the three storage bags had already died, and he easily opened them. He poured out all the items inside. Apart from some miscellaneous items such as clothes, the valuable items were divided into several categories and placed on the table. The most direct thing was a pile of spirit stones, a total of more than four hundred spirit stones. Next were the magical instruments: nine low-grade magical instruments, seven mid-grade magical instruments, and six high-grade magical instruments. So many magical instruments obviously didn't belong to one person. Among the mid-grade magical instruments, three were damaged. In addition to the blue stone, flame dagger, red thread needle, and green pearl used by the two, there was also a black long staff and a tortoise shell shield among the high-grade magical instruments. Those two were both late-stage Qi Refining cultivators, and one was even at the peak of Qi Refining. They generally wouldn't be interested in mid-grade magical instruments. Combined with what Mu Lao said, the people who besieged him were evil cultivators who specialized in robbing lone cultivators. Although such cultivators were denounced by everyone and called evil cultivators by cultivators, their strength was generally not weak. After all, cultivators who dared to do such a cost-free business would have been killed long ago if they didn't have some skills. The three people who besieged Mu Lao were said to be organized evil cultivators from Evil Wind Valley. They often robbed lone cultivators, and the rulers of Falling Star City had even issued wanted orders. There was a reward of several hundred spirit stones for each evil cultivator killed. Zhang Ling was not interested in this reward. He didn't want to attract the attention of others. In addition to the magical instruments, he also found several bottles of pills. They were all pills that could be used in the middle and late stages of Qi Refining. However, these pills were very common. He could refine them himself, so he didn't care about them. The remaining items were a small pile of spirit herbs and demon beast materials. These things were also quite valuable. After counting these gains, Zhang Ling also sighed at the carefree life of these evil cultivators. This cost-free business was indeed the fastest way to get rich. The value of the items in the two storage bags alone was close to two thousand spirit stones. Whether they were obtained by robbery or plundered by them, they were now all cheaper for him. Zhang Ling calmed down and put these things into the storage bag after classifying them. Then he sat on the stone bed and considered the gains and losses of this trip to Falling Star Mountain Range. With his current strength, ordinary late-stage Qi Refining cultivators and demon beasts were no longer a problem. However, the methods of cultivators' fighting were often strange and unpredictable. It was not necessarily the case that a higher cultivation level would win. This time, the cold star sand in his Wind and Sand Gourd was completely used up. Fortunately, Tianyu Pavilion gave a gourd of cold star sand when he purchased the magical instrument. As long as he refines it again, this magical instrument can restore its power.
Magical instruments, spirit talismans, and spells were all key to determining victory or defeat. Even some spirit beasts and puppets could greatly enhance the strength of cultivators, just like the black-clothed man's Entangling Technique was used so skillfully this time. The giant root vines alone caused him a great loss. If this person had not consumed a lot of energy dealing with Mu Lao earlier, and was careless in the end, he would have been corroded to death by the giant root vine he controlled, and his life would have been unpredictable. Giant root vines were not common. Giant root vines had a chance to grow only in the root systems of giant spirit trees that were five hundred years old. They were difficult to collect. He didn't know how the black-clothed man got them. He did not find any spirit plant seeds used to perform the Entangling Technique in the two storage bags of the black-clothed man. He didn't believe that this person had used up all the spirit seeds for performing the Entangling Technique. It seemed that they were hidden on his body and were eventually corroded by the green liquid of the giant root vines. However, he was satisfied with these gains. Zhang Ling patted the storage bag and took out four magical instruments. Placed them aside. They were the blue stone, green round bead, tortoise shell shield, and the red thin needle. The power was different. Then Zhang Ling began to refine these magical instruments. Generally speaking, Qi Refining cultivators can only control three magical instruments at the same time. It is not impossible to increase the number, but controlling multiple magical instruments at the same time will consume too much of the cultivator's divine sense, and the power of the magical instruments will be reduced. For Qi Refining cultivators, controlling three magical instruments at the same time is the best choice. Moreover, some special cultivators, such as talisman cultivators and sword cultivators, who practice specific methods, generally only control one magical instrument. These magical instruments are mostly custom-made and only fit themselves. Even if others get them, they cannot exert their full power. However, for Zhang Ling, these magical instruments have different uses, and it is a good choice to use them as spare magical instruments. In the next few days, he was in the cave refining and familiarizing himself with these magical instruments. The blue stone magical instrument can emit threads, which are also sticky and can restrain his cold star sand to a certain extent. The tortoise shell shield is a defensive magical instrument, and its defense power is no less than his Earth Element Shield. The red thread needle is a magical instrument specially used for sneak attacks and breaking defenses. If used well, it can kill enemies invisibly, just like the black-clothed man attacked him. Moreover, it is quenched with poison. Although it cannot immediately kill the cultivator, it can also make the cultivator's spiritual power run poorly. This is fatal in a fight. The last magical instrument he chose was the green round bead. This is a wood-attributed magical instrument that can amplify the power of wood-attributed spells. The black-clothed man used this magical instrument to quickly cast the Entangling Technique. Most of these special magical instruments are custom-made magical instruments, which can exert great power in the hands of cultivators who practice wood-attributed techniques. Zhang Ling cultivates earth-attributed techniques. This magical instrument can also be used, but it can only exert half of its power. The reason for refining this magical instrument is because the other group of spiritual energy in the body is wood-attributed spiritual power. In addition to the earth spiritual power cultivated from the Thick Earth Technique, there is still a spiritual power in his body, which he got after the weird vine parasitized in his body. After several years of cultivation, this group of spiritual power is also slowly increasing. Zhang Ling has naturally studied it. Based on his understanding of the spiritual power of Qi Refining cultivators, the concentration of this group of spiritual power has reached the level of the fifth or sixth layer of Qi Refining. It is rare in the cultivation world to have two kinds of spiritual power in the body. Generally, only cultivators who practice multi-attribute techniques will have this situation.
