Tang Zhen only had to look at it and he was sure that this colorful spar was definitely not a mortal thing.

Even if it is not possible to figure out the operating principle of this device in a short time, one thing can be confirmed, that is, this colorful spar is definitely the core component of the energy absorbing device and has an irreplaceable role.

Although he wanted to take away the colorful spar directly, Tang Zhen cared more about the energy absorbing device, for fear that it would be destroyed.

After personal experience, Tang Zhen knew exactly how effective the energy absorbing device was, and its operating principle was worthy of further study.

Although I don't know how large the range of energy absorption is, it is designed and manufactured specifically for the world energy used by the monks, but it can still absorb any form of energy.

For example, in the original world, electric energy is applied to almost every corner.

If this can be achieved, once it is activated, it will be tantamount to a terrible disaster!

When electric energy cannot be used, the entire modern society will be completely paralyzed. It is not an exaggeration to say that it will return to the primitive era overnight.

The monks in Loucheng fought in the world, and the chances of encountering the world of science and technology were extremely high. As long as this device was activated at that time, then the indigenous resistance forces would collapse without attack.

Without modern technological weapons as a reliance, when facing the Loucheng monks who are proficient in cold weapon fighting and the skill of using guns are extremely accurate, the indigenous forces will become vulnerable!

Therefore, after Tang Zhen knew of the existence of this energy absorbing device, he began to pay attention and tried to copy and move it to the Holy Dragon City.

The colorful crystal in front of me is undoubtedly the core of energy storage. God knows what material it is, and it can store such a terrifying and huge amount of energy.

If it exploded at this time, Tang Zhen would never doubt that the entire city would be razed to the ground in an instant!

While he was observing the entire device, a sound of wind came from around him, and then a figure appeared beside him, it was the Silver Wing King with its wings stretched out.

Although the cultivation base was restricted, the Silver Wing King’s flying ability did not have any effect. As Tang Zhen entered this underground space, she followed closely behind.

Following Tang Zhen's line of sight, Silver Wing King also saw the colorful crystal, and after looking at it for a while, he showed a hint of surprise.

Obviously she has also felt that this colorful crystal contains quite terrifying energy!

"Wild King, what is this thing on earth, shouldn't it explode?"

Two more soft sounds came, but it was the Blood River King and the White Bone King, but compared to Tang Zhen and the Silver Wing King, their two way of falling was relying on a rope.

One foot stepped inside the rope sleeve, the other hand pulled the rope, the two glanced at the colorful crystals and asked Tang Zhen.

Tang Zhen glanced at the three of them and nodded softly.

When these three guys came down at this time, obviously they didn't want to miss the good things that might exist, or they were afraid of what Tang Zhen would use, but just to restore their own cultivation.

They are not familiar with Tang Zhen. When dealing with this important matter of life and death, they must do it themselves to be at ease!

"Tang will turn off the energy absorption device next. There may be danger during this period. Will the three continue to watch?"

Tang Zhen retracted his gaze from the colorful crystal, turned his head to look at the three rulers beside him, with a joking smile on his mouth.

If these three guys continue to stay ignorant, Tang Zhen can't guarantee that there will be no "surprise" next.

Blood River King and the other three rule kings heard the words, looked at each other, and then said that they would not delay Tang Zhen's affairs, they just waited aside.

In just a few minutes, the three of them have checked the surrounding area and determined that the only valuable thing in this underground space apart from the incomprehensible energy absorption device may be the colorful crystal.

But this thing is a hot potato, and it might be blown to pieces, so the three of them held an attitude of keeping away from this colorful crystal.

Another point is that the three of them have already seen that Tang Zhen is extremely concerned about the energy absorbing device, and they have even revealed a hint of their own intentions.

Although Tang Zhen's approach was somewhat domineering, the hearts of the three rulers were surprisingly absent from competing.

Firstly, because Tang Zhen contributed the most in this matter, he should have the priority to choose the trophy.

In addition, most of the monks in Loucheng are very repulsive of technological items, are not used to using them, and will not maintain them. If there is a problem at the critical moment, they may lose their lives!

Therefore, even if the power of many technological weapons is huge, the monks in Loucheng will persistently use the original cold weapons.

What's more, those secretly forged swords, as well as strong bows and crossbows with abnormal range, may not be much worse than firearms and weapons, and they are more adaptable!

So this colorful spar should be given to Tang Zhen as a favor!

Seeing the three rulers retreating to the side, Tang Zhen nodded in satisfaction, and slowly landed at the bottom of the underground space.

Turning off the energy absorbing device also requires a special password and identity authority. Using the mobile phone application that is about to be closed, Tang Zhen quickly began to crack it.

When the cracking was completed, the phone interface fell into darkness again, apparently it was completely shut down!

After fiddling a few times on the translucent operating platform, I saw that the energy absorption tower tens of meters high began to make a "buzzing" sound, and then closed from both ends one by one, and finally plunged into darkness completely.

The originally brightly lit underground space suddenly became dark and quiet.

At the moment the energy absorbing device was closed, Tang Zhen immediately felt a trace of energy appear out of thin air, gradually filling the surrounding world.

It's just that the process of energy recovery is very slow. If you want to restore the original strength to the original strength, the monks in Loucheng have to wait at least a few days!

The entire process of closing was calm, and the onlookers of the Loucheng monks saw the underground space darkened, and immediately felt the traces of heaven and earth energy, and the invisible shackles on their bodies disappeared completely.

On the contrary, there was a shocking vision outside the building.

When Tang Zhen turned off the energy absorbing device, the sky above the building trembled suddenly, and then it was like a stone thrown into the calm water, ripples rippling around.

In the process of the surging waves, the colors are constantly changing, and at the same time, the strands of materialized energy that resemble clouds and mists are constantly falling to the ground like mist and rain.

This energy mist rain fell on people, and immediately melted away, refreshing people.

After being exposed to the energy mist and rain, the plants that have been albino immediately began to turn green at a speed visible to the naked eye, and then went crazy and began to pull up. The original inch-high grass grew to the same height as an adult. .

After the pieces of ruins and houses were moistened by the energy mist and rain, they began to change from gray to green. It was moss and various plants that grew wildly, which completely covered the walls and ruins in a blink of an eye.

It is estimated that it will not take long before this reinforced concrete city will immediately become a green ocean!

The citizens hiding at home, as well as the members of the resistance organization waiting outside, were stunned by the change in front of them. They all looked at the center of the change, their eyes full of complexity and horror.
