Inside the vault, there was silence.

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

Chu Duan is the head of a sect, so the choice he makes should take more into account, after all, the treasures brought out here can not only be used by himself, but also by the sect.

A quarter of an hour passed, Chu Duan still didn't come up with a result, the treasures he had in his eyes were far more than three, and this was the first time in his life that he had made such a difficult choice.

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

"King Qingyin, I don't know what to build?" Chu Duan asked.

"I don't have anything to build yì. Qingyin Wang Dao, he didn't take the initiative to build yì, but Chu Duan took the initiative to ask differently: "It's difficult to choose, that is, choose what you need most, and in addition, there is a way to get more treasures." ”

"What method?" Chu Duan hurriedly asked.

"Swap. King Qingyin said: "The prince can get three treasures for free, and if he wants to get more treasures, that is, the equivalent exchange." ”

"Equivalent exchange ......" Chu Duan only felt as if his thinking had been opened a door, and suddenly opened up, and for the equivalent exchange, he didn't feel strange and resistant, after all, it was already good to be able to get three treasures for free, as for the things that were not worked for, of course everyone wanted to have as much as possible, however, it was impossible.

To reap, there must be pay, this is the unchanging truth between heaven and earth.

A sect master like Chu Duan understands this more clearly, otherwise, how a sect can survive and how to become strong, just cultivating disciples is enough to consume resources, and eventually the entire sect cannot be maintained and disbanded.

Don't contradict it, Chu Duan was thinking at this time. In exchange for what?

Sword World?

Obviously, the weight is full, and Chu Duan also believes that as soon as the Sword Heaven and Earth comes out, he can definitely exchange more treasures, but he will not exchange them, because that is the inheritance of the True God Sword Sect, and it is his foundation, even if it is a treasure, he can't get it, and Chu Duan will not exchange it.

As for those top-of-the-line sword poses. It's pretty much the same thing.

So, what about the demon slaying arm armor, the black gold mask, and the heavenly puppet?

As soon as the thought turned, he was immediately vetoed by Chu Duan.

Three kinds of treasures, one is more precious than the other, the Demon Suppression Arm Armor can improve his strength very well, and it is a pity to exchange it.

"That being the case. Let's exchange it for the Secret Method of the Ring of Colors. Chu Duan made a decision.

The Colorful Ring is a secret method of Yuan Shen defense, up to level seven, and in the entire Canglan Dynasty, there is no such secret method at all. Even in the entire Deep Blue World, the Primordial God Defense Secret Technique that has reached level seven will definitely not exceed ten.

If Chu Duan is willing, take out this colorful ring and put it up for auction. You will definitely get huge benefits, and you can even gather all the heaven and earth essences needed for the second level of the Sword God's Descending Secret Method, and you can also get other things.

Metamystical Law. For each grade, the value varies greatly.

If you take it out for auction, you can indeed get huge benefits, but at the same time, it is accompanied by huge risks, there must be a lot of people who are targeted, and when the time comes, not only will you be in trouble, but also the True Sword Sect, that kind of trouble is not something that a Canglan Dynasty or the Heavenly Sword Saint Venerable can resist.

"However, only the first six rings are used. Chu Duan decided again.

The Colorful Ring is level seven, and the Sixth Ring is level six, which is better than level five, but the value is much better.

Thinking of this, Chu Duan raised his head and looked at King Qingyin again.

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

"What do you want in exchange?" Before King Qingyin could answer, the old man's voice sounded, and it came slowly, it was the old man who guarded the secret vault who spoke.

"A sixth-level meta-mystical method. Chu Duan opened his mouth and said, "Sixth-level Yuan Shen Defense Secret Method!"

King Qingyin's eyes suddenly widened, glaring at the boss, showing that he was very shocked in his heart.

He heard it right, what Chu Duan said was the sixth-level Yuanshen Defense Secret Method, and in the entire Imperial Secret Treasury, there were only five Yuanshen Defense Secret Methods, and only one of them had reached Level 5.

Level 6 is theoretically only one level above level five, but its meaning is very different.

The fifth level represents the fifth-level primordial god, and the sixth level represents the sixth-level primordial god, and the difference between the primordial gods is one level, and the gap is huge.

Under normal circumstances, in order for a cultivator to become a seven-star saint level, he must have a four-level primordial god, and the cultivation of the primordial god is very difficult, the vast majority of the nine-star saint-level powerhouses have only reached the fifth level, only the peerless powerhouse can reach the sixth-level level, as for the seventh level, it is the level that belongs to the silver primordial god, and it belongs to the level of the holy emperor.

In other words, the sixth-level Yuan Mystic Law, in a certain sense, belongs to the peerless powerhouse level, while the seventh-level Yuan Mystic Law has reached the level of the Holy Emperor level.

Of course, some Yuan Shen cultivators with strong souls may have a sixth-level Yuan Shen when they are at the nine-star saint level.

But in any case, the higher the level of the meta-mystical method, the higher the value, and the difference in value by one level is immeasurable.

King Qingyin really wanted to see what Chu Duan would come up with in exchange, but he didn't expect it to be a sixth-level Yuan Mystery Method, or a very precious Yuan Shen Defense Secret Method, so he was stunned for a moment, and his thoughts seemed to freeze.

Su Lao didn't say anything for a while, obviously, he was also shocked.

"Sixth-level Yuan Shen Defense Secret Method, extremely valuable......" The old man's voice sounded again, a little slower, and seemed to be thinking as he spoke: "In addition to the three treasures that you originally got for free, you can also choose ten more." ”

"Ten pieces!" King Qingyin had just come to his senses and was shocked again.

Ten treasures, the treasures of the Imperial Vault, are not ordinary treasures, each one taken out, will cause a large-scale sensation of treasures, and the value is extraordinary.

Counting the three pieces obtained for free, that is to say, Chu Duan can obtain thirteen treasures.

Of course, among the treasures in the Imperial Vault, some treasures are of higher value, and some of them are of relatively low value, such as the Yuan Mystic Method, the second-level Yuan Shen Defense Secret Method, which naturally cannot be compared with the fifth-level Yuan Shen Defense Secret Method.

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

After all, as long as you are not a fool, you will not put the fifth-level Yuanshen Defense Secret Method and choose the second-level Yuanshen Defense Secret Method.

In addition, when choosing a treasure, it is natural to choose the most suitable, and 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 if it is not suitable.

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

Chu Duan's mind turned, and he agreed.

With a sixth-level primordial god defense secret method, exchange ten treasures, or choose your own, fair.

As for the seventh-level Yuan Shen Defense Secret Method, it is definitely possible to exchange more treasures, however, not all treasures are needed by Chu Duan, just some that are suitable for his own and suitable for the development of the sect.

The quota of thirteen treasures was increased by five times all of a sudden, and Chu Duan also breathed a sigh of relief, finally there was no need to be so embarrassed.

However, before exchanging again, Chu Duan also had to take out the exchange of the Yuan Shen Defense Secret Method.

A piece of white jade fell from above.

"With the power of the divine soul, just record the sixth-level primordial god defense secret method. Su Lao said.

After Chu Duan caught the white jade, the power of the divine soul seeped into it, condensed into a sword, and began to record.

The first six rings of the Colorful Ring start from the first ring to the end of the sixth ring, as for the name, Chu Duan did not use the Colorful Ring, nor the Six-Colored Ring, but changed a name, called the Six-Colored Ring.

Soon it was recorded, re-thrown, and vanished.

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

King Qingyin showed a look of envy.

Ten treasures.

The quota of thirteen treasures is quite sufficient, and Chu Duan has also seen all the treasures in the secret vault, and in his heart, he has already made a conclusion.

First of all, it is naturally a Yuan Shen cultivation secret method, and the fifth-level one is immediately picked out.

Then, there is a secret method of attacking the Yuan Shen up to level five, which is also selected.

The spirit of fire, the spirit of wind, and the spirit of darkness are all selected, and in this way, Chu Duan still has eight treasures left.

Heart Refining Valley, a secret treasure, cannot help cultivation, but it can allow those who enter to hone their spiritual will and hone their minds.

The path of cultivation has many temptations and dangers, and if you can't uphold your true heart, it's easy to get lost in it, and in the end, your cultivation will come to naught.

Therefore, cultivators not only need to improve their cultivation and strength, but also need to pay attention to the tempering of their minds, which also has indirect benefits for becoming a saint-level powerhouse in the future, and even for the cultivation of the primordial gods, it can also play a certain role, although it is not very obvious.

The Battle Mania Hall is a secret treasure like the Juyuan Tower, but the Juyuan Tower is used to cultivate Yuan Force, and the Battle Mania Hall is used to cultivate the physique.

The True Sword Sect is a sword cultivation sect, which can cultivate Yuan Li and also cultivate physique.

In this way, Chu Duan still has six treasure places.

Compared with the previous three treasure quotas racking their brains to think about the choice, the current thinking is different, thinking about what is more appropriate.

Like those primordial elixirs or elixirs, they are also very good, reaching a certain amount, and they are the same treasures together, but they are consumables, and they will be gone if they are used.

Therefore, Chu Duan did not rush to make a choice, just spare.

Spirit sword, there are a total of seven here, six of them are low-grade spirit swords, only one has reached the middle grade, but it is an ordinary medium-grade spirit sword, but even if it is a low-grade spirit sword, it also has a very high value, so Chu Duan chose the medium-grade spirit sword, named Liehuang Spirit Sword.

To get the Liehuang Spirit Sword, you only need to refine it, and Chu Duan will be able to make the two spirit swords fight in the future, and with the two spirit swords in hand, the strength will be even stronger. (To be continued......)
