Godly Student

"Yes, this formation will be of great use after it is built. In the future, if someone encounters disadvantages to our Promise Palace, we can raise the cultivation base of a large number of disciples to a higher level in a very short time.

So this formation is either not built, or if it is built, it must be built well! "Cheng Yu said seriously.

The Promise Palace is not like the Cheng family, the Cheng family is still too weak and has no social status. But Wuji Palace is so famous and powerful, who dares to provoke Wuji Palace easily?

It is not uncommon to have spiritual veins in such sects, not only Wuji Palace, but also Xuantianzong, Tianmozong, Fahong Temple, etc., they all have spiritual veins in their sects, this is no secret .

But so what if they knew? Do they still dare to rob? I really don't want to live.

But in the Cheng family, he didn't dare to take out the spirit veins to strengthen the formation, that would only attract more enemies. So he only used a small piece of spirit crystal. In this case, even if someone coveted it, at most he would lose a piece of spirit crystal.

"There is some truth in what you said, so it's up to you!" Qing Yuanzi said after thinking about it.

"As for alchemy, although you don't need it now, other brothers in the same sect also need it. If you have Tiantongcao, I can refine some Mahayana pills for the sect!" Cheng Yu said.

"Mahayana pill? Can you refine Mahayana pill?" Qing Yuanzi and Qing Xuzi said in surprise.

The Mahayana pill is the pill needed to break through the advanced Mahayana pill during the fusion period. Even their Wuji Palace doesn't have such a pill. No matter what quality Mahayana pills are, they are extremely precious.

A low-grade Mahayana pill once appeared in the Qiongyu Tower auction. At that time, I heard that it was snatched madly, and finally bought it at a very scary price.

If Cheng Yu could refine the Mahayana pill, wouldn't the Wuji Palace greatly increase the success rate of the disciples entering the Mahayana stage.

"As long as there are medicinal herbs, I can indeed try to refine them, but I can't guarantee success, nor can I guarantee the quality. It's very likely that it's just a low-grade Mahayana pill." Cheng Yu said with some expectation.

Because the rank of Mahayana Pill is too high, his Feng Yan is not enough, unless Feng Yan can advance to become Long Yan, in that case, he will be able to refine the top-grade Mahayana Pill.

But the opportunity is rare, there are so many medicinal materials in the Promise Palace, he can definitely try to refine it!

"Okay! Tiantongcao is available in our sect,

Because our alchemists have no way to refine Mahayana alchemy, the Tiantongcao has been kept. "Qing Yuanzi said happily.

"Actually, although you don't need to cross the catastrophe now, I can help you refine some Transcendence Pills first. Even if the master and uncle don't need it, it can be used by other people in the sect!" Cheng Yu thought for a while Said.

"What? Transcending Tribulation Pill? You can still refine Transcending Tribulation Pill?" The two said in shock.

If Cheng Yu's ability to refine the Mahayana Pill really surprised them, but the refining of the Transcending Tribulation Pill was really shocking. Because, they have never heard of someone successfully refining the Transcending Tribulation Pill. This is just a elixir that has appeared in the classics, and no one can really refine it.

"I still dare to lie to you, I only revealed this secret for the future of everyone in Wuji Palace, but like I said just now, I can't guarantee success, nor can I guarantee quality!" Cheng Yu said with some pride.

Although my strength is not as good as these two old guys, but my ability in other aspects may not be comparable to them.

It's a pity that what he has now is only Fengyan. If it is Long Yan, as long as it is not an elixir, he will not be restricted by his cultivation and realm at all. As long as there are enough materials, he can refine all the pills in the lower realm.

"You can't believe everything you say, kid. How about this, you first refine a Mahayana pill and come out to see it. If possible, we will let you refine the Transcending Tribulation Pill, otherwise, we can only wait and wait for you The strength of alchemy will go one step further, and I will refine it for you!" Qing Yuanzi thought for a while and said.

The medicinal materials for refining these elixirs are all extremely precious, so how can I let him try it out.

"That's okay!" Cheng Yu thought for a while and found it made sense.

After all, he wasn't sure about refining the top-grade pill, so to him, if he couldn't make the top-grade pill, it wouldn't mean much.

After all, the highest-grade elixir can increase the success rate by 100%, while the top-grade pill can increase the success rate by 80%, the middle-grade pill can increase the success rate by 60%, and the low-grade pill can increase the success rate by 40%.

If you can only refine low-grade pills, it would be a waste of resources. It would be better if your own Feng Yan becomes Long Yan in the future, then all the pills in the human world can be refined.

---------------------

The next day, Qing Yuanzi brought Cheng Yu to the back mountain!

This back mountain usually does not allow disciples to enter, and only disciples who have obtained special permission can enter.

"Is there any secret here?" Cheng Yu asked curiously. After walking into the back mountain, he obviously felt that the aura here became very strong.

"Because the spiritual vein of our sect is here!"

"Is there only a spiritual vein? It doesn't have to be so secret!" Cheng Yu said.

"You'll find out after a while!" Qing Yuanzi shook his head and said.

"This..." The two walked inside, and it turned out to be an open space, and inside the open space was a huge stone floating in the air, surrounded by six crystals floating around, and under the big stone But it is a yin and yang array.

"Uncle, the six pieces around are spirit crystals!" Cheng Yu asked curiously.

"That's right! Those six pieces are indeed spirit crystals!" Qing Yuanzi nodded.

"But what is this boulder in the middle? Why is it so dark? Is there any mystery in it?" Cheng Yu didn't understand what it was, and the stone was hanging in the air in pitch black.

"This is passed down from generation to generation in our sect!"

"It was passed down from our sect? But it's just a stone, at most it's a strange, dark stone." Cheng Yu said puzzled.

There is nothing special about this stone except that it is pitch black. The ancestors of the Promise Palace handed down such a big stone, is there any mystery?

"This is the secret of our sect, and it cannot be revealed casually!" Qing Yuanzi shook his head and said.

"Uncle, no way, just tell me about our relationship!" The more Qing Yuanzi was unwilling to say it, the more curious he became.

Others didn't dare to talk nonsense when they saw Qing Yuanzi, and only Cheng Yu dared to talk to Qing Yuanzi like that.

"It's said that this is a secret of the sect. Only the head of the sect can know about it. Even your master doesn't know about it!" Qing Yuanzi shook his head again, unwilling to say more.

"No way, you don't even know the identity of my master?" Cheng Yu became even more curious when he heard this!
