Live Quest: Inheritance of Mountain-moving Technique at the Beginning, Unicorn Pattern

　　However, Qin Feng did not answer, but his eyes flickered slightly, staring at the entrance of the cave.

　　After a while, the gunfire gradually stopped.

　　In the whole cave, the original mysterious silence was restored.

　　This made everyone look different.

　　"Are we now... going to go back and have a look?"

　　Li Xueer asked, with worry in her eyes.

　　It's not how deep their friendship is with Kos and the North American Soldier King, but the bitterness of their lips and teeth:

　　Once the two really encounter some kind of accident, it means...

　　There is some kind of strange creature at the entrance of the cave...

　　Running towards here!

　　"It's not necessary."

　　Hearing Lin Xueer's words, Qin Feng's face flashed a trace of contemplation, and replied lightly.

　　Immediately afterwards, he turned his head and continued to explore the depths.

　　"I think so too!"

　　"They are our competitors after all... they have nothing to do with us!"

　　Lin Yu and Su Shishi nodded and supported Qin Feng's choice.

　　The crowd continued to explore ahead.

　　Before they knew it, everyone had penetrated into the grotto for about [-] meters.

　　With the deepening of exploration, the rock walls around this grotto also changed from black to light gray...

　　The cross-sectional distance of the entire grotto is also slightly larger, reaching about three meters.

　　Can accommodate more people.

　　"grey…"

　　Looking at the changes in the surrounding rock walls, Lin Yu couldn't help but feel a little curious.

　　"How could it be this color?"

　　In the conference room, the two professors who saw the gray rock walls around them were also a little surprised.

　　"Could it be..."

　　"Grey sedimentary rock."

　　In the grotto, Qin Feng said lightly.

　　These words made Professor He in the conference room instantly widen his eyes.

　　"It's really a lime sedimentary rock!"

　　Professor He was surprised and said in a low voice.

　　"Grey sedimentary rocks...what is that? I've only heard of sedimentary rocks."

　　Mr. Sun couldn't help but have some doubts.

　　Generally, sedimentary rocks are all black, and it is impossible to have such a state.

　　"Lime sedimentary rock is also a type of sedimentary rock."

　　Professor He said.

　　"Sedimentary rocks are generally rocks formed by the differentiation and precipitation of surface rocks. Most of them are black, and most of them are located about two or three meters underground, which is very shallow."

　　"It can be directly excavated."

　　Professor He explained.

　　"But lime sedimentary rocks are different."

　　"The dust and rock are distributed [-] meters underground and are very deep."

　　Qian Lao was a little surprised.

　　"what?"

　　"Go deep into the ground ten thousand meters?"

　　Hearing Qian Lao's words, everyone's eyes widened.

　　To know…

　　With the current technology of human beings, it is actually the latest type of drilling rig, which can only go deep into the ground about 5 kilometers.

　　[-] meters deep...

　　There is no such machine in the world today!

　　"Old Qian, you must not have misremembered..."

　　Sun Dong swallowed a mouthful of water and couldn't help but ask.

　　"Our level of technology now... When have we descended [-] meters underground?"

　　"yes…"

　　Many program directors also nodded.

　　"Have you forgotten the North Star Project?"

　　Qian Lao sighed and said lightly.

　　Hearing this term, everyone's heart tensed.

　　Polaris is the highest-level project led by the five permanent members of the United Nations:

　　Explore whether there are mutant creatures under the earth's crust.

　　In this project, the most important thing is to develop a ground-boring machine that can go deep into the ground.

　　It is also the drilling rig in the North Star program that can penetrate [-] meters underground - breaking the world record.

　　However, this project is too complicated, the project research is also very slow, and there has been no new news for many years.

　　"Could it be that…"

　　"The North Star Project... New progress?"

　　Everyone was surprised.

　　"Yes."

　　Qian Lao nodded seriously.

　　"A month ago, the Polaris program made a breakthrough and successfully developed the latest rig, the Illuminati."

　　"It has successfully penetrated 1 meters underground."

　　Qian Lao swallowed a mouthful of saliva.

　　"It is also at the position of 1 meters underground that many scientists found in horror that the rocks of the crust have changed from the original black sedimentary rocks...to completely gray."

　　Qian Lao said.

　　"According to speculation, it was the fission of the earth's crust 2 million years ago that caused the volcanic eruption and pressed a large piece of rock under the ground..."

　　"Those gray sedimentary rocks are exactly the same as the gray rock walls in this Longling Grotto!"

　　"what?"

　　Everyone took a deep breath and looked at the quantum screen in disbelief.

　　"Could it be that…"

　　"The gray rock walls in the Longling Grottoes...are all gray sedimentary rocks [-] meters underground?"

　　Sun Dong's voice trembled a little.

　　"Yes."

　　Qian Lao nodded solemnly.

　　There was an uproar...

　　"how so…"

　　Many well-informed program crew leaders also became restless.

　　The rock buried nearly [-] meters underground...

　　How would it appear here?

　　It's so weird...

　　Many senior members of the program group were silent, and for a while they didn't know what to say.

　　"Right now, only one conclusion can be drawn."

　　After a long time, Qian Lao cleared his throat.

　　"That is... This Longling Grotto is definitely not formed naturally... It must have been built after transportation."

　　"Who is it... who can break through the technological limits of human beings, go deep into the ground for [-] meters, and bring the rocks buried in the depths of [-] meters to the ground to build this Longling Grottoes?".

Chapter 333

　　Qian Lao was a little surprised.

　　Hearing Qian Lao's words, many senior members of the program group fell silent one after another...

　　People can't imagine...

　　What kind of creature is it, breaking through the limits of human beings and going deep into the ground for [-] meters...
