Receiving the promise of the refining elder, Bai Yi smiled slightly and said, "Two pieces of Tiangang Rock, exchange for nine silk and sideburns jade." ”

"What!"

Zhou Cheng stopped doing it when he heard this, and said angrily: "Sideburns jade and nine-fold silk are both precious refining materials, each of which costs at least two or three hundred thousand low-grade spirit stones, and two Tiangang rocks can't be replaced." ”

It is true that ordinary Tiangang Rock cannot be exchanged for the two materials Bai Yi said, but the Tiangang Rock in Bai Yi's hand is not an ordinary quality, and it is more than enough to change sideburns and nine silks.

Since Zhou Cheng was unwilling, Bai Yi didn't force it, and said: "Then it's okay to bother the elder to go to Fang City, two ordinary Tiangang rocks, at most, can repair Zhenyun Zhong by fifty percent, and restore it to its full power It is a dream." ”

Zhou Cheng's face immediately fell, with his attainments in refining, how could he not see the quality of the Tiangang Rock in Bai Yi's hand, what he said just now was just to make some benefits, don't look at him as Elder Cangyun, his net worth is not rich, if he has tens of thousands of spirit stones, it will be considered a small fortune.

"There is no sideburn jade, there is still one of the nine-fold silk, exchange it for a piece of Tiangang Rock for you, if you want to buy sideburns jade, go to Nanzhao Kingdom to go around, it is difficult to see that kind of material in Dapu's Xiuzhenfang City." Zhou Cheng looked at the stone in the other party's hand reluctantly and said.

Knowing that the Refining Hall did not even have sideburn jade, Bai Yi frowned slightly, and then handed the Tiangang Rock in his hand to Zhou Cheng, and he himself got an almost transparent silk thread, which was one zhang long.

Nine-fold silk is the silk of silkworm demon beasts, with excellent toughness, don't look at the nine-fold silk is thinner than hair, but it can easily strangle gold and iron, and even magic weapons can't cut it, it is an extremely rare refining material.

Zhou Cheng put away the Tiangang Rock, pursed his lips, and said with a sad face: "Boy, can that piece of Tiangang Rock also be exchanged for the old man, with these two pieces of Tiangang Rock, the power of Zhenyun Zhong should be able to recover to close to ninety percent, you can change some other materials." ”

Since the refining elders all had a pleading tone, Bai Yi had no choice but to take out the second piece of Tiangang Rock as well, and said, "Then it's better to exchange some Huiling Pills." ”

Hui Ling Pill is the highest reward of the last three sects on martial arts, and it is also the most precious one of the seven spiritual pills, each of which can improve the cultivation of the foundation building monk for half a year out of thin air, and is worth tens of thousands of spirit stones, which can be called a luxury among the foundation building monks.

The Hui Ling Pill cannot be taken continuously, and the monks of the Foundation Building Realm can take one pill at most half a year, otherwise the domineering spiritual power contained in the Hui Ling Pill will destroy the meridians in the monk's body, so even if the Foundation Building Monk is very wealthy, don't think about relying on the Hui Ling Pill to quickly break through to the Golden Pill.

Zhou Cheng pondered for a while, nodded and said: "Four Huiling Pills, in exchange for the Tiangang Rock in your hand, you will not lose this deal." ”

The value of the four Hui Ling Pills was around 200,000 spirit stones, Bai Yi did not hesitate at all, and handed over the second piece of Tiangang Rock to the refining elder, and the four Hui Ling Pills in exchange were also easily put into the storage bag.

After the transaction was completed, the two began to discuss the repair of Zhenyun Zhong with satisfaction, since the materials have been finalized, there is only the repair method left, sometimes Zhou Cheng proposed a means of repair, which was denied by Bai Yi in a few words, and sometimes Bai Yi proposed a refining technique ingeniously, and it would also be canceled by Zhou as very immature.

In this way, the old and the young studied in the refining hall for three days before they came up with a final result, and after determining the final repair method, Bai Yi Shi Shiran left the hall and returned to his residence.

In the past three days, some of the refining methods he occasionally said were by no means secrets that a Jindan elder like Zhou Cheng could access, although it was not much, but it was enough for the refining elder to benefit a lot, as for the final repair of Zhenyun Zhong, Bai Yi would not interfere.

Without Danhuo, even if he wanted to repair Zhenyun Bell, it would be impossible to repair it.

The kind of Zhenyun Bell that surpasses the high-level magic weapon can't be repaired with earth fire, that is, Zhou Cheng goes all out, and he can restore eighty or ninety percent of the power of Zhenyun Bell, but once it is attacked, as long as there are three Yuanying powerhouses joining forces, Zhenyun Bell will collapse and shatter in an instant.

After all, this strange treasure has been urged by Cangyun's disciples for thousands of years, and it has long been dilapidated, and it is not easy to exert the last residual heat, and if you want to restore it as before, only Cangyun Ancestor can make a move.

Thinking of Zhou Cheng's leaky ancestor, Bai Yi smiled indifferently, looked at the direction of Qingshan and said to himself: "Enter the Tao with a weapon, Wu Cheng, you are really too addicted, in the past few thousand years, I am afraid that your realm will not improve much, but I don't know if your refining attainments can catch up with you as a teacher......

The Wu Cheng in Bai Yi's mouth is the Cangyun Ancestor, if someone else hears a young man call the strong man who founded the Cangyun Sect like this, he must not be frightened to drop his jaw.

Bai Yi didn't use the Hui Ling Pill, since Zhou Cheng gave the qualification for the cultivation of the Twenty-Day Ancestor Hall, he was sure enough to advance to the middle stage of foundation building after those twenty days, and the Hui Ling Pill was still reserved for the middle stage of foundation building, after all, the later stage of each great realm was the most difficult time.

In the empty refining hall, Bai Yi became the only disciple, and the others were all refining the blood pattern gold day and night in the earth fire cave, and the door of the refining hall had been closed, blocking a woman's waiting for many days.

When Bai Yi entered the Earth Fire Cave again and began to refine some auxiliary pills, Ni Qiuyu had already come to the outside of the Refining Hall for the first time.

Ever since she heard that Bai Yi had returned, she was so happy that she could hardly sleep at night, and her worries for many days were dissipated by the news, but every time she came to the Refining Hall, she would see the cold door, and no one paid attention to how to call the door.

In Cangyun Sect, it is a felony to break into the main hall, if Ni Qiuyu smashes the door of the refining hall and rushes in, then the refining elder has the right to kill him, there is no need for any reason, just a crime of forcibly breaking into the refining hall is a capital crime in the sect.

Ni Qiuyu's feelings for Bai Yi are very complicated, not just a simple liking, but also mixed with some faint family affection, in her eyes, the slightly thin teenager is like her younger brother, which makes people worry and worry.

Before Bai Yi fell into the ground, Ni Qiuyu returned to his residence early because of his blushing face, and he didn't even have the heart to continue watching Wu Dou, so he escaped a catastrophe, and there were not many disciples who could stay on the ground in the Cangyun Tribulation.

In the early morning of this day, Ni Qiuyu came to the door of the Refining Hall as usual, although the door was still cold, as long as she remembered that the young man in the hall was safe and sound, she would feel very stable and happy, so a trip to the Refining Hall once a day has become a habit for Ni Qiuyu these days.

Squeak!

The cold door was slowly pushed open, and the young man in the door strode out, and saw the woman standing outside the door at a loss.

"Senior Sister Ni, why are you here?"

Bai Yi asked suspiciously, watching the other party's pretty face become redder and redder, patted his head, and said, "Senior sister is going to the Earth Fire Cave, these days our disciples in the Refining Hall are all refining materials in the Earth Fire Cave, the Earth Fire Cave is already overcrowded and temporarily closed, it should be able to reopen after a month, Senior Sister doesn't need to worry." ”
