In the secret library, there is silence.

King Qingyin also put away his smile and looked at Chu Mu who was thinking not far away without any impatient, because he knew that such a choice was quite important.

Chu Mu is the leader of a sect, so the choices he made should be considered more. After all, the treasures brought here can not only be used by him, but also by the sect.

A quarter of an hour passed, but Chu Mu still couldn't come up with the result. The treasures he liked were far more than three, and this was the first time he had such a difficult choice in his life.

Looking up, he saw the King Qingyin not far away, and Chu Mu's heart suddenly moved.

"King Qingyin, don't know any suggestions?" Chu Mu asked.

"I don't have any good suggestions." King Qingyin did not take the initiative to make suggestions, but Chu Mu asked for it on his own initiative was different: "It's difficult to choose, that is to choose what you need most. In addition, there is another way to get more treasures."

"What method?" Chu Mu asked hurriedly.

"Exchange." King Qingyin said: "The king and prince can get three treasures for free. If you want to get more treasures, it is equivalent exchange."

"Equivalent exchange..." Chu Mu only felt that his thinking was opened as if a door was opened, and he suddenly realized. He did not find it strange or conflicted with equivalent exchange. After all, it was already very good to be able to get three treasures for free. As for things that were not worth it, of course everyone hoped that more would be better, but that was impossible.

There will inevitably be efforts to gain, which is the unchanging truth between heaven and earth.

A sect leader like Chu Mu understood this better. Otherwise, how a sect survives and becomes stronger, just cultivating disciples would be enough to consume all resources, and eventually the entire sect could not be maintained and disbanded.

Not resistant, Chu Mu was thinking about what to use for exchange?

Sword Heaven and Earth?

Obviously, it is very important, and Chu Mu also believes that once the sword world comes out, he can definitely exchange more treasures, but he will not exchange them, because it is the inheritance of the True God Sword Sect and its foundation. Even if it is a treasure, Chu Mu will not exchange them.

As for those top-level sword poses, it's almost the same thing.

So, what about the three types of Demon-Subduing Arm Armor, Black Gold Mask, and Tiante?

As soon as his thoughts changed, Chu Mu immediately rejected it.

Three kinds of treasures, one is more precious than the other. The Demon-Subduing Arm Armor can greatly improve his strength. It is a pity to exchange it for exchange.

"Since that's the case, use the Seven Colorful Ring Secret Technique to exchange it." Chu Mu made the decision.

The Seven Colorful Ring is a secret technique for the defense of the soul, up to level seven. Such a secret technique can’t be found in the entire Canglan Dynasty. Even in the entire deep blue world, the secret technique for the defense of the soul that reaches level seven will definitely not exceed ten.

If Chu Mu was willing to take out the colorful ring for auction, he would definitely gain huge benefits. He could even gather all the essence of heaven and earth needed for the second level of the Sword God's arrival secret technique, and he could also get other things.

The mysterious method of the Yuan Dynasty. Each level is different, and the value varies greatly.

If you take it out for auction, you can indeed get huge benefits, but with huge risks, there will definitely be many people on the target. At that time, not only will you be in trouble, but the True Sword Sect is the same. Such troubles cannot be resisted by a Canglan Dynasty or the Saint of Heavenly Sword.

"However, only the first six rings are used." Chu Mu decided to say again.

The seven-colored ring is level seven, while the six-ring ring is level six, which is better than level five and one level, but its value is much better than many.

Thinking of this, Chu Mu looked up and looked at King Qingyin again.

"Your Excellency Qingyin King, how should you exchange if you want to exchange?" Chu Mu asked.

"What are you going to exchange for?" Before the Qingyin King could answer, the old man's voice rang out and slowly came. It was Mr. Su who was guarding the secret library who was speaking.

"A level six soul secret technique." Chu Mu said: "A level six soul secret technique!"

The King of Qingyin suddenly glared, staring at the boss, showing that he was very shocked.

He heard it correctly. What Chu Mu said was the level 6 soul defense secret technique. In the entire royal secret library, there were only five secret techniques for the soul defense, and only one of them reached level 5.

In theory, the sixth level is only one level above level five, but its meaning is very different.

Level 5 represents the fifth level primordial spirit, and Level 6 represents the sixth level primordial spirit. The difference between the souls is one level, which is extremely large.

Under normal circumstances, if a cultivator wants to become a seven-star holy level, he must have a level four soul. It is difficult to cultivate and advance the soul. The soul level of most nine-star holy level strong people only reaches level five. Only peerless strong people can reach level six. As for level seven, it belongs to the silver primordial spirit level and the Holy Emperor level.

In other words, the level 6 Yuan Shen Mystery Method belongs to the level of peerless power in a certain sense, while the level 7 Yuan Shen Mystery Method reaches the level of the Holy Emperor.

Of course, some soul-powered cultivators may have level six souls at the Nine Star Saint level.

But no matter what, the higher the level of the Yuanshen magic, the higher the value, and the difference between the next level is immeasurable.

King Qingyin wanted to see what Chu Mu would do to exchange it, but he didn't expect it to be a level six-level mysterious method or a very precious secret method of soul defense. He was stunned for a moment, his thinking was frozen.

Mr. Su didn't say anything for a moment, obviously, he was also shocked.

"The secret method of level 6 soul defense is extremely valuable..." Old Su's old voice sounded again, slower, as if he was talking while thinking: "In addition to the three treasures he originally obtained for free, you can also choose ten more."

"Ten pieces!" King Qingyin woke up and was shocked again.

Ten treasures, the treasures in the Imperial Secret Library are not ordinary treasures. Every treasure that will cause a large-scale sensation and is of extraordinary value when taken out.

Including the three items obtained for free, Chu Mu can obtain thirteen treasures.

Of course, some treasures in the dynasty secret library have higher value, while some treasures have relatively low value, such as the Yuanshen Mystery Method and the second-level Yuanshen Defense Secret Method, which naturally cannot be compared with the fifth-level Yuanshen Defense Secret Method.

If you want to divide it in detail, it will undoubtedly be very troublesome and difficult to do.

After all, as long as you are not a fool, you will not choose the level 5 soul defense secret technique and choose the level 2 soul defense secret technique.

In addition, when choosing a treasure, you naturally need to choose the most suitable one. The most suitable treasure is not necessarily the most valuable treasure, but no matter how high the value of the treasure is, it is in vain.

Because of this, Mr. Su defined the exchange amount of ten treasures.

Chu Mu's mind changed and agreed.

It is fair to use a level 6 soul defense secret technique to exchange ten treasures, but it is better to choose by yourself.

As for the level seven-level soul defense secret technique, you can definitely exchange more treasures. However, not all treasures are needed, Chu Mu only needs them, just some suitable for his or her own sect development.

The quota of thirteen treasures was increased by five times at once, and Chu Mu also breathed a sigh of relief. Finally, there was no need to be so embarrassed.

However, before the exchange, Chu Mu had to take out the secret method of the exchange of soul defense.

A piece of white jade fell over the sky.

"Use the power of the soul to record the secret method of level 6 soul defense." said Mr. Su.

After Chu Mu caught the white jade, the power of his soul penetrated into it, condensed into a sword, and began to record it.

The first six rings of the Colorful Ring start from the first ring until the end of the sixth ring. As for the name, Chu Mu did not use the Colorful Ring or the Six-Colored Ring, but changed his name, called the Six-Colored Ring.

The record was completed soon, and it was thrown up again, and disappeared.

After a while, Mr. Su's voice rang again: "The transaction is established, you can choose the treasure."

The King of Qingyin showed an envious look.

Ten treasures.

The quota for the thirteen treasures was quite sufficient, and Chu Mu had also seen all the treasures in the secret warehouse and had already made a conclusion in his mind.

First of all, it is naturally a secret method of practicing the soul, which is selected immediately by level five.

Then, a level five-level secret soul attack technique was also selected.

The essence of fire, essence of wind, essence of darkness, and essence of darkness are all selected. In this way, Chu Mu still has eight treasure quotas left.

The Valley of Refining Heart is a secret treasure that cannot help practice, but it can allow those who enter to temper their spiritual will and mind.

The way of cultivation is full of temptations and dangers. If you cannot uphold your original intention, you will easily get lost in it, and eventually lead to your cultivation being gone.

Therefore, cultivators not only need to improve their cultivation and strength, but also need to pay attention to the training of their minds. This is also indirectly beneficial to becoming a Saint-level powerful person in the future, and can even help the cultivation of the soul, although it is not very obvious.

Zhanmakuai Hall is a secret treasure like the Juyuan Tower, but the Juyuan Tower is used to cultivate the Yuan power, while Zhanmakuai Hall is used to cultivate the body.

The True Sword Sect is a sword cultivation sect that can cultivate the essence and the body.

In this way, Chu Mu still has six treasure quotas.

Compared with the previous three treasure quotations that racked their brains to think, the current thinking is different, and it is about what is more appropriate to consider.

Like those spiritual medicines or elixirs like the soul, they are also very good. They reach a certain amount and are the same treasures when combined, but they are consumables and will be gone if used.

So, Chu Mu was not in a hurry to make a choice, just backup.

There are seven spiritual swords here in total, and six are all low-grade spiritual swords. Only one of them reaches the middle grade, but it is an ordinary medium-grade spiritual sword. But even the lower-grade spiritual swords have extremely high value, so Chu Mu chose the middle-grade spiritual sword, called Liehuang Spiritual Sword.
