Mortals ask the immortals

When the Guishan brothers revealed the situation of the treasure house to him that day, although they did not mention any details, it is not difficult to guess that a treasure house that is only used to store spiritual stones and treasures is at most a small domain, and the Guishan brothers are unlikely to go to great lengths to transplant spiritual veins into it.

Therefore, the spiritual power source of the formations and restrictions at the entrance of the treasure house is probably made of things like top-grade spiritual stones.

After arriving at the scene, the situation is basically consistent with his judgment. Judging from the structure of the ground formations and restrictions, both use spiritual stones to supply spiritual power.

There is no difference in essence between using spiritual stones as spiritual power sources and using spiritual veins as spiritual power sources. Both use spiritual energy to convert spiritual energy into spiritual power and then supply it to the restrictions.

The only difference is that spiritual veins are more durable. Of course, the cost of using spiritual veins will definitely be much greater than using spiritual stones.

Therefore, generally only large domains will specifically transplant spiritual veins into them.

Just like the Broken Star Palace established by Broken Star, some of the formations and restrictions in it also use spiritual stones to provide spiritual power, but the main part of them must still be supplied by spiritual veins.

Otherwise, if such a huge realm wanted to rely on spirit stones to support its operation, the consumption over the years would undoubtedly be an unimaginable number.

Even so, after more than 100,000 years of consumption, the Broken Star Palace has almost reached the point of exhaustion, with its spirit veins dried up and spirit stones used up.

The treasure house built by the Guishan brothers must not be large in scale, and it is reasonable to use spirit stones to supply spirit power to the ban and formation. There is nothing wrong with it.

But the problem is that the Guishan brothers were captured by the Huntian Demon King and imprisoned in the dungeon of Huolin Island at least a thousand years ago.

In other words, if the ban at the entrance of the treasure house has not been broken by anyone, it has at least lasted for thousands of years.

There are thousands of spirit nodes in this ban, which is not too many, but not too few. The consumption of thousands of years is definitely not a small amount of spirit power.

After careful observation, he found that there were only eighty-one top-grade spirit stones hidden underground to supply spirit power to this ban.

It is not impossible for eighty-one top-grade spirit stones to maintain this level of ban for thousands of years. After all, the consumption of the ban is much smaller when no one attacks.

However, even if these eighty-one top-grade spirit stones can maintain this restriction for thousands of years, the spiritual energy in them will definitely be consumed by more than half, and there will not be much left.

As the spiritual energy in these spirit stones decreases, the spiritual power supply to the restriction will also decrease, and the strength of the entire restriction will also decrease.

It is inevitable to use spirit stones to supply spiritual power to the restriction.

However, in his observation, the spiritual power supply of this restriction is too sufficient, and the spiritual power strength has hardly decreased. It does not look like a restriction that has been maintained for thousands of years!

Judging from the current situation of this restriction, the duration of this restriction is no more than a hundred years at most!

This is very strange!

You know, Brother Guishan has been imprisoned for thousands of years!

Even if his calculation of the spiritual power consumption of this restriction has some errors, there should not be such a big difference.

What's more, he has a lot of attainments in the field of restrictions and is very confident in his calculations.

He dares to be sure that the eighty-one top-grade spirit stones that supply spiritual power to this restriction are definitely not the original batch!

Otherwise, the spiritual energy in this batch of spiritual stones should have been close to exhaustion or used up.

Combined with the current situation, Duan Qing can only think of one possibility.

The treasure house of the Guishan brothers was opened by others after the Guishan brothers were imprisoned, and afterwards, the spiritual stones that originally provided spiritual energy to the ban were specially replaced!

Otherwise, this counterintuitive situation would not have occurred.

Who opened the treasure house left by the Guishan brothers?

After this person opened the treasure house, why did he restore the ban at the entrance of the treasure house to its original state?

Could it be that the Shanhe Gang still exists, discovered this treasure house, and has been using it until now?

No... The Guishan brothers built this treasure house because they were ready to run away at any time because of their identities as a member of the Sui clan. They left this hand specially.

Even if the people of the Shanhe Gang discovered this treasure house, they would at most search out everything inside, and there was no reason to continue using the treasure house.

And most importantly, it is unclear whether the Shanhe Gang still exists after the disappearance of the Guishan brothers!

Similarly, there is no reason for other people who discovered this treasure house to keep it until now after opening it!

For a moment, Duan Qing was full of doubts and couldn't figure out the reason.

"Friend Han, can this restriction be broken?"

Just as Duan Qing was thinking secretly, Bi Yiqiu asked Han Xinghe again, and his tone was obviously not as polite as before.

This Han is so arrogant that he asked for 40% of the profit. If he can't do anything about this restriction now, he will never let this person go easily!

Han Xinghe obviously became a little impatient with Bi Yiqiu's repeated questioning.

"What are you panicking about? Although this restriction has some tricks, it is still not difficult for Han!"

"Don't disturb Han again!"

As he said that, Han Xinghe sat cross-legged with his eyes closed, and seemed to start to deduce the core spiritual power node of the restriction.

Bi Yiqiu saw this, although he felt a little unhappy, he didn't say anything more and waited patiently.

This wait lasted for almost an hour.

When Bi Yi Qiu was almost impatient, Han Xinghe finally let out a long breath and completed the deduction.

Han Xinghe stood up from the ground, looked carefully at the restriction on the ground, and then retreated to the corner of the cave while offering a stack of yellow talismans in his hand.

When he retreated to a corner of the cave, Han Xinghe signaled Bi Yiqiu to step back.

After Bi Yiqiu also stepped back, Han Xinghe frowned, and all the talismans in his hand flew out of his hand and shot towards the restriction light curtain in the center of the cave.

As soon as the talisman flew out of his hand, it shrank rapidly. When it approached the restriction light curtain, it had changed from the initial three-finger width to less than the size of a little finger.

A total of nine pocket-sized talismans were firmly attached to the surface of the restriction light curtain, forming a small circle, encircling one of the spiritual power nodes.

The next moment, the nine talismans exploded together, making a huge roar, and a shock wave spread out.

Duan Qing, who was in a corner of the cave, ignored the impact of the talisman explosion without blinking, and his eyes never left the forbidden light curtain for a moment.

After a while, the aftermath dissipated, and the forbidden light curtain in the center of the cave gradually dissipated.

Seeing this scene, Duan Qing nodded imperceptibly.

Although Han Xinghe's method of breaking the ban was a bit rough, the effect was still acceptable.

The principle of Han Xinghe's breaking the ban was actually similar to his Nine Separation Ban.

His Nine Separation Ban was to use the spiritual power field to isolate the core spiritual power node, preventing the core spiritual power node from resonating with the spiritual power of other nodes.

Han Xinghe's method of breaking the ban was to directly destroy the deduced core spiritual power node, which could also achieve a similar effect.

However, compared with his Nine Separation Ban, this method was obviously much more crude.
