Wang Yinguo looked over at first sight and found that the laboratory of Zhenren Qingxu was really big.

This also uses the magical power of space to turn a small space in the mountain belly into a super large research room, which is equivalent to the size of a small town.

In this research room, Qingxu Zhenren has set up many researched devices.

Some of these devices have been completely discarded, obviously not meeting the design expectations, while others are protected by small formations with precious things, which belongs to the kind of inventions he attaches great importance to.

"Uncle Master."

"Sect Master, elders."

"Please go inside, the thing I've been fiddling with recently is there."

Zhenren Qingxu walked aside and led the way for everyone.

Here, not only are there all kinds of devices alone, but also two disciples of Zhenren Qingxu, who are also busy working there, but they just don’t understand what they are doing.

"Master!"

"Oh, Sect Master, all elders!"

"Uncle Master?!"

The two disciples who were less than Xuxian were shocked when they saw the general bosses appearing one after another, and they didn't even know where to put their hands.

Especially when they saw that Wang Yanguo, the uncle who rarely left Xuanyu Peak, also appeared among the crowd and was welcomed by the stars like the moon, they were even more excited.

For the true immortal Qingxu Zhenren, it is a great honor for anyone present to visit.

"Is this the device to detect spiritual power fluctuations?"

Soon, Wang Yinguo and others saw the latest research and inventions of Zhenren Qingxu.

This device is actually not very big.

This installation can be accommodated in any house.

Moreover, Wang Yinguo also carefully checked the structure of this device and found that it did not use too expensive materials. It was just a relatively ordinary refining material, which formed the spiritual power fluctuation monitoring device in front of him.

When he saw this, he couldn't help but be moved by the research spirit of Zhenren Qingxu.

Such ordinary materials can be used to create such a useful device, which can completely replace a golden immortal or even a Daluo golden immortal to monitor the abnormal situation of the world. This is really a precedent for scientific research and technology in the prehistoric world.

Such talents, if they are placed at the right time, will definitely be the kind of great figure who has been famous for all ages.

Unfortunately, in an environment like the prehistoric world where immortality is respected, Zhenren Qingxu is really a bit in awe.

"Qingxu Zhenren."

"Why would you explain in detail how this device works?"

After discovering that everyone was very interested in this thing, Elder Chunleizi said to Zhenren Qingxu like this.

"good!"

After hearing this, everyone nodded in agreement.

If everyone didn't care much about this before, now the uncle Wang Yinguo has clearly expressed his concern, so of course everyone should join in the fun and see what the situation is.

"Uncle Master, Sect Master, and all elders."

"The disciple suddenly had this idea, but it was actually-"

When talking about this matter, Zhenren Qingxu had a lot to say, so he had this idea until he had a specific idea and how to use devices to monitor the fluctuations of spiritual power, etc., and explained it in detail to everyone.

It has been half a day since I said this.

Everyone listened with relish. After all, although not everyone is familiar with this kind of thing, the principles of formations involved are clear at a glance, which has inspired everyone to improve in this area.

Even monks who do not focus on weapon refining formations as their main business can reflect on some of their problems in their practice and then wake up.

In short, this trip was not in vain.

"The Sect Master, you can consider allocating more resources to the Qingxu Zhenren."

"If some components are raised by one level, the volume of this device should be much smaller, but it will not be weakened in function."

Wang Yinguo mentioned his opinions to the sect leader Ye Hanxing.

"Should this be the case."

Ye Hanxing nodded and expressed that he fully agreed.

In fact, after everyone visited the research room of Qingxu Zhenren and saw the achievements of his inventions, they had this idea.

Take the set of spiritual power fluctuation detection equipment in front of you as an example. If it is successfully put into use, it will not only be difficult to detect, but also detect every move around you all day long. As long as an alarm system is added to it, it can completely replace the early warning function of the Golden Immortal Elders.

For the entire sect, this is equivalent to letting go of dozens of Golden Immortal Elders, and being able to solve the problem of insufficient manpower in the sect to a greater extent, which is naturally a good thing.

Moreover, the research ideas of True Man Qingxu have indeed inspired everyone a lot.

If you follow this idea, you may be able to improve it in many places, bringing the role of the formation to the extreme, and reducing the investment in labor to the extreme.

After Ye Hanxing agreed to Wang Yinguo's proposal, he immediately ordered the treatment of Zhenren Qingxu to the level equivalent to that of the Golden Immortal Elder, and also enjoyed the greatest need in material support. He also stated that if there is an important invention, he can directly apply for the highest level of support from the sect, not only for material aspects, but also for human resources assistance.

Wang Yinguo casually pointed out several directions for improvement, and then asked the question about the fluctuations of spiritual power that the Supreme Elder Ling Yunzi said.

"I heard that there was an abnormal spiritual power change a few days ago?"

Wang Yanguo asked Zhenren Qingxu.

"Report to the uncle of the junior teacher."

"This is indeed the case."

"I have been trying to calculate the total amount of spiritual energy in the prehistoric world recently, but this work is too complicated and it is difficult to solve the problem for a while. However, by measuring the numerical changes in the fluctuations of spiritual energy, I found some clues."

"The day before yesterday, the total amount of spiritual energy in the prehistoric world was reduced by less than three hundred thousand."

"This matter is completely unreasonable, but it is calculated that it is indeed the case."

"If the uncle of the junior teacher asked about this, I'm afraid the disciples would think they had calculated it wrong."

"After all, from a personal feeling, there is no such feeling at all."

After hearing Wang Yinguo's words, Zhenren Qingxu immediately said in surprise.

"Has the spiritual energy in the prehistoric world been reduced?"

"What happened?"

"This is impossible!"

When everyone heard this, they immediately exclaimed.

"If the spiritual energy in the prehistoric world is reduced, how could we be unaware of anything?"

"Although three out of 100,000 spiritual energy doesn't sound much, it is enough to make people feel alert in reality."

"Qingxuzi, are you making a mistake?"

Elder Chunleizi asked in surprise.

Everyone present had the same feeling, thinking that Qingxuzi had made a mistake.

Spiritual energy is the foundation for survival and cultivation of monks in the prehistoric world. If they lose the spiritual energy foundation, there will be no big difference between living in the sea of ​​chaos.

After all, if you lose your spiritual energy, no one can continue to practice.

The impact of this matter was too great, so serious that everyone was worried.

"This is indeed strange."

"When I returned from the Chaos Sea, I noticed this. The estimated results are basically the same as those obtained by the real person Qingxu."

"In the prehistoric world, about three-tenths of the spiritual energy has indeed disappeared."

Wang Yinguo looked at everyone and then expressed his discovery.

When everyone heard Wang Yinguo say this, they were shocked and silent.

They really didn't expect that such a situation would happen in the prehistoric world.

And everyone looked at each other and found that no one noticed this detail, which was terrible.

After listening for a long time, someone spoke.

"The foundation of the spiritual stone world."

"Now that something happened, but I don't know what to do?"

Ye Hanxing said with some concern.

"I don't know if the Taoist saint is clear about this matter?"

"If it's clear, it's easy to say."

"If even the Taoist saint is not clear about this matter, it will be difficult."

Supreme Elder Ling Yunzi said this.

"Who can control the changes in the spiritual energy of the prehistoric world?"

"Apart from the Taoist Ancestor or the Heavenly Way, even the Six Saints of the Prehistoric World cannot do it, right?"
