Feng Yun and Cheng Yu stayed in the cave for another three days. In these three days, they talk a lot about their personal things while cuddling on the bed.
"I am going." Cheng Yu said softly while embracing Feng Yun, "But I promised that I will return to you one day."
Cupping her face, Feng Yun kissed her on her forehead and said, "You know how to find me, if you encounter any danger then send me a signal through the sound transmission jade."
"I will." Cheng Yu nodded her head and smiled slightly. She was worried that Feng Yun would try to stop her or ask her the reason for leaving. But he didn't say anything, clearly understanding her thoughts.
"I have a gift for you, you will like them." Suddenly, Feng Yun remembered something and said. Releasing Cheng Yu from his arms, he took out an old iron chest from his space ring.
"What is it?" Cheng Yu asked curiously, Feng Yun smile, and indicated her to open the chest.
Cheng Yu looked at the old iron chest for a moment, slowly open it. Inside the chest, there were two red-colored curved blades with a length of one foot, excluding a strong killing aura. These blades which he got from the ancient cave.
Cheng Yu's eyes shone brightly after seeing the two curved blade, she reached out her right hand and pick up the blade, she slowly traces her left hand's fingers on the blade, feeling the sharpness of the blade.
"Are these..." When she sensed the powerful spirit emitting by the blades, she was shocked. She looked at Feng Yun and asked to confirm her thoughts.
"Yes, there are two Peak-Grade Earth Ranked Weapons made with Red Meteoroid Iron, extremely sharp, these could pierce through defense body armor below Sky Ranked." Feng Yun said, explaining about the blades. The Red Meteoroid Iron was very rare in the Blazing Sun Dynasty, even one found the Red Meteoroid Iron, then to make a weapon with Red Meteoroid Iron was extremely difficult.
Feng Yun was sure that only two or three weapons refiner could be able to refine the weapon with Red Meteoroid Iron in the Blazing Sun Dynasty or even Long Imperial Dynasty.
"These are too valuable." Cheng Yu wanted to refuse him. But Feng Yun's firm gaze made her unable to refuse. After placing the blades in the space ring, she hugged Feng Yun and gave him a passionate kiss.
"This is for you, it was given to me by my mother." Cheng Yu unlock the chain from her neck then placing around Feng Yun's neck. A blue-colored crystal hanging on the chain, obviously the pendant was invaluable to her.
After both of them, came out of the cave.
"Take care of yourself." Cheng Yu said, before leaving, soon she disappeared into the woods.
Feng Yun stood there a few minutes while caressing the pendant of Cheng Yu with his fingers as he could still feel her warmth from the pendant. After living with her for five days, now Feng Yun was a little empty, after taking a deep breath, collecting his things. Feng Yun also left the cave.
Cheng Yu who was standing on a tall tree, looking at the back of Feng Yun, there was a sadness in her eyes, as she parted with Feng Yun.
"I will surely come back." She whispered quietly as a bright smile bloomed on her face. She jumped to the next tree, going in the opposite direction of Feng Yun.
....
Feng Yun's mission was to find some unique type of stones which was used for making the sound transmission talisman. The Divine Wind Mountain Range was very vast, there were many spirit stones many but most were all low-grade spirit mines, there are one or two Middle-Grade Spirit Stone mines in the Divine Wind Mountain Range which were guarded by the Mystic Heaven Peak.
This was also the reason that Spiritual Qi in the Divine Wind Mountain Range is much denser than the outer world.
There was a story about the Mystic Heaven Peak, that below the Mystic Peak there was a huge mine of the Mid-Grade Spirit Stones, it was discovered by the founder of the Mystic Heaven Peak, that is why he decided to establish the Mystic Heaven Peak in the Divine Wind Mountain Range.
Soon Feng Yun came to the old spirit Stone mine which was emptied by the Mystic Heaven Peak.
Inside the Divine Wind Mountains, only abandoned Spirit Stones Mines were accessible to outer sect disciples. Those that were still in the midst of mining operations were forbidden. Thus searching for Spirit Stones was like a task in finding omitted treasures.
There was one more problem, the abandoned Spirit Stones Mines could be dangerous because many Spirit beasts resided in the Spirit Mines due to the thick spiritual Qi inside the Spirit Stones Mines.
Feng Yun entered an old mine, it was dark inside, Feng Yun took out a luminous crystal, making the cave a little more visible.
Feng Yun searched for two hours but could find anything in the spirit mine, after he entered the next one, it was also empty. Now Feng Yun understood why the disciple didn't want to take this type of mission.
After searching for six hours, Feng Yun finally finds some transmission stones in the spirit mine which was regularly larger than previous ones, Feng Yun entered deeper into the Stone Mine.
Chi! Chi!
As Feng Yun entered the depth of the mine, many strange cries of the spirit beast sound in the cave.
Feng Yun looked at the ceiling of the cave and found out there were tens of Black Spiders running on the ceiling of the cave. Each one of the spiders was the size of three to four feet.�
Their strength was not enough to threaten any Foundation Establishment Realm Cultivator much less Feng Yun, but it was their numbers that could scare any Gold Core Realm Cultivator.
Most of the Small spirit beasts like mice, spiders, ants used to live in a nest form, it protects them being hunted down by the Bigger Spirit Beasts.
