Tang Zhen only needed to look at it to determine that this colorful spar was definitely not ordinary.

Even if it is impossible to figure out the operation principle of this device in a short period of time, one thing can be confirmed, that is, this colorful spar is definitely the core component of the energy absorption device, and it has an irreplaceable role.

Although he really wanted to take this colorful spar away, Tang Zhen was more concerned about this energy absorption device, for fear that it would be destroyed.

After experiencing it himself, Tang Zhen knew very well how powerful the effect of this energy absorption device was, and its operating principle was also worthy of in-depth study.

Although I don't know how large the range of energy absorption is, whether it is specially designed and manufactured for the heaven and earth energy used by the monks, or whether it can absorb any form of energy.

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

If this can be done, it will be tantamount to a terrible catastrophe if it is activated!

In the case of the inability to apply electrical energy, the entire modern society will be completely paralyzed, and it is not an exaggeration to say that it will return to the primitive era overnight.

The monks of Loucheng conquered the Ten Thousand Worlds and had a great chance of encountering the world of technology, and as long as this device was activated at that time, the indigenous resistance would be defeated.

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

Therefore, after Tang Zhen learned that this kind of energy absorption device existed, he had already begun to pay attention to it, and tried to copy and move it to the Holy Dragon City.

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

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

Just as he was observing the entire device, there was a gust of wind around him, and then a figure appeared beside him, it was the Silver Wing King with his wings extended.

Although her cultivation was restricted, the Silver Wing King's flying ability had no effect, and as Tang Zhen entered this underground space, she followed closely behind

Following Tang Zhen's line of sight, the Silver Wing King also saw the colorful crystal, and after a little look, he showed a hint of surprise on his face.

Obviously, she had also sensed that there was quite a terrifying energy stored inside this colorful crystal!

"Barbarian King, what the hell is this, it shouldn't explode, right?"

Two more soft noises came, but it was the Blood River King and the White Bone King, but compared to Tang Zhen and the Silver Wing King, the way the two of them fell was by a rope.

With one foot in the rope sleeve and the other hand pulling the rope, the two glanced at the colorful crystals and asked Tang Zhen.

Tang Zhen glanced at the three of them when he heard this, and nodded lightly.

These three guys came down at this time, obviously because they didn't want to miss the good things that might exist, or they were afraid that Tang Zhen would use some means to just restore their cultivation.

They are not familiar with Tang Zhen, and when dealing with such an important matter of life and death, they must do it themselves to rest assured!

"Tang is going to turn off this energy absorption device next, there may be danger during the period, do the three of you continue to watch from the sidelines?"

Tang Zhen withdrew his gaze from the colorful crystal, and turned his head to look at the three law kings beside him, with a hint of a playful smile on the corner of his mouth.

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

Hearing this, the three Law Kings such as the Blood River King glanced at each other, and then said that they would not delay Tang Zhen's matter, and they would just wait on the sidelines.

In just a few minutes, the three of them had already looked at the surrounding area, and determined that the only thing of value in this underground space, except for the incomprehensible energy absorption device, might be the colorful crystal.

But this thing is a hot potato, and if you don't do it, it will be blown to pieces, so for this colorful crystal, the three of them all have a respectful attitude.

In addition, the three of them had already seen that Tang Zhen was extremely concerned about the energy absorption device, and even revealed a trace of his own intentions.

Although Tang Zhen's approach was a bit domineering, the hearts of the three law kings were surprisingly not in the heart of the competition.

First, because Tang Zhen contributed the most in this matter, he should have the qualifications to give priority to the selection of loot.

In addition, the vast majority of Loucheng monks are very repulsive to scientific and technological items, they are not used to it, and they will not maintain it, and 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 of Loucheng will insist on using the original cold weapons.

What's more, those swords forged by secret methods, as well as the strong bows and hard crossbows with perverted range, may not be much worse than the lethality of firearms and weapons, and they are more adaptable!

So this colorful spar is better to give it to Tang Zhen as a favor!

Seeing that the three Law Kings retreated to the side, Tang Zhen nodded with satisfaction and slowly landed at the bottom of the underground space.

Turning off the energy absorption device also requires a special password and identity permission, and using the mobile phone application that is about to be closed, Tang Zhen quickly cracked it.

When the cracking is completed, the mobile phone interface is once again in the dark, apparently it has been completely shut down!

After fiddling with the translucent operating platform a few times, I saw that the energy absorption tower, which was dozens of meters high, began to emit a "buzzing" sound, and then closed from both ends one by one, and finally fell into darkness completely.

The originally brightly lit underground space became dark and silent in an instant.

At the moment when the energy absorption device was turned off, Tang Zhen immediately felt a trace of energy appear out of thin air, gradually filling the surrounding heaven and earth.

It's just that the process of recovering this energy is very slow, and if the Loucheng monks want to recover to their original strength, they will have to wait for at least a few days!

The whole closing process was undisturbed, and those onlookers saw that after the underground space was darkened, they immediately felt the traces of the energy of heaven and earth, and the invisible shackles on their bodies also disappeared completely.

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

The moment Tang Zhen turned off the energy absorption device, the sky above the building suddenly trembled, and then it was like a stone thrown into the calm water, and the ripples continued to ripple in all directions.

In the process of surging waves, the colors are constantly changing, and at the same time, a trace of materialized energy filaments like clouds and mist continue to fall to the ground like fog and rain.

This energy mist rain fell on the person, and immediately melted away, which made people's spirits lift.

And those plants that have been whitened immediately began to turn green at a speed visible to the naked eye after being exposed to the energy mist rain, and then they began to rise up like crazy, and the grass that was originally an inch tall actually grew to the same height as adults.

Patches of ruins and houses began to change from gray to green after being moistened by the energy mist and rain, which was a crazy growth of moss and various plants, and in the blink of an eye, the walls and ruins were completely covered.

It is estimated that it will not be long before this reinforced concrete city will immediately turn into a sea of green!

The citizens who were hiding in their homes, as well as the members of the resistance group waiting outside, were stunned by the anomaly in front of them, and they all looked at the center of the anomaly, their eyes full of complexity and horror.
