Chapter 917: In the dark (2/2)

A faint air current blows from bottom to top, like a pair of invisible big hands slightly supporting them.

No matter the Chaos Blade prisoners or the elites of the Youfu Army, they are all good at lightening the body. The smooth walls of the cave are also inlaid with a circle of threads that can take advantage of them, but they can't help them.

A lot of communication flying insects hovered around each of the Youfu Army, but after five or six kilometers deep underground, the communication flying insects lost contact with the above and could only be used for internal communication.

The deeper the earth, the thicker the black mist, and in the end he could barely see his fingers.

Even if they carry a lot of searchlights and fluorescent flying insects, they can only vaguely outline each other.

The exploration team descended in the shaft for more than half an hour, and finally landed to the bottom of the shaft.

There was a buzzing sound from all around, and the light of the searchlight turned to dim yellow. I swept towards the sound, but saw that the scouting insects and monsters that were dropped into the shaft just now were all like flies without their heads. Turn around in circles.

Seeing the searchlight, many flying insects slammed into the light headlessly, ”pupupupupu” knocked out the light and shadow.

”The magnetic field here is extremely chaotic, and it is not clear at all to distinguish between east and south. It is no wonder that these monsters will lose control.”

A Youfu Army was holding a multifunctional compass refined by the Star Federation, and the pointer on it turned as fast as a fan.

”The air quality is acceptable. Although the oxygen content is only 2.5%, no deadly toxic ingredients have been detected.”

Another Youfu Army used the crystal brain proficiently.

War is the best means of communication between the two civilizations. In the years of chaotic battles with the Tianyuan realm, a large number of magic weapons and cultivation techniques have flowed into the blood demon realm and become popular.

”First use the sonic detector for surveying and mapping, and then explore in a counterclockwise direction. The view here is extremely poor. Pay attention to everyone gathering together, including prisoners, to report every five minutes to prevent anyone from being left behind.”

The whirlpool quickly said.

The surrounding area was black, and the searchlight could only shine up to ten meters away, and then it was swallowed by cloud-like black. The fluorescent flying insects lost their control and hovered around them.

Fluorescence flickers, not only fails to effectively illuminate, but it renders the atmosphere even more tense.

”Bo! Bo! Bo!”

The monotonous sound wave echoed more than 20,000 meters underground, quickly outlined the general environment around them, and fed back into the biochemical chips attached to their eyeballs.

From the results of sonic mapping, this is a space with a length of five to six hundred meters.

Compared with the magnificent and vast underground temple above, it is naturally insignificant.

The space is completely integrated, there is no column, but there is a huge bulge in the center, which looks like a boulder and a throne, more like a huge coffin.

The entire space is covered with knee-deep water, and I don't know if the space is broken, the groundwater pouring in from all around, or it was accumulated here 40,000 years ago.

After 40,000 years of transpiration and fermentation, this stagnant water has turned into a viscous liquid that is almost grease, and every step taken will pull out filaments.

However, in addition to the high level of bacteria content, it is not too toxic and corrosive.

”Five captives in front, five captives behind, start exploring!”

The exploration team reached the edge of the space and moved counterclockwise, but the walls were made up of huge black stone blocks, with rows of tiny tiny prints engraved on them.

”what is this?”

Seven or eight searchlights were shining up, but the black rock wall of forty to fifty meters high, from top to bottom, was filled with words, numbers, and runes the size of rice grains.

Some texts are written neatly and neatly, but some texts are very scribbled, and some texts are like ghost paintings and celestial scripts, which makes people dizzy at first glance.

However, judging from the structure of the font and the angle and strength of the carving into the rock, they are all made by the same person.

”It seems to be some kind of cultivation method, it's not right, it's some kind of secret method for modulating Gu poison, it's not right, how can it be like a flow chart for refining magic weapons?”

”Understood, it is a mixture of many chaotic and wonderful skills. These skills are intermittent, scribble, and there are many traces of smearing and modification. It should be...draft!”

”It seems that this secret room is really a chaotic training room and a research room. He took the surrounding walls as drafts to think about new exercises. Whenever he has any ideas, he will engrave it on the wall through his true energy. !”

”Quickly, scan all the traces on the wall, transport it back to it, and let the experts analyze it carefully, and try to resolve a few useful secrets!”

On the four walls, there were a lot of chaotic thoughts and thoughts, in addition to these, there were a lot of beast-like claw marks, destroying many words and formulas.

Many claw marks, a few meters deep into the wall, resemble extremely tyrannical beasts, raging and surviving.
