Su Yu and the others stood on the edge of the holy pit. They looked at the bottomless pit, and a terrifying aura came from it.

Su Yu was very confused and asked, "I originally thought that your Forester's base camp was in this pit, but I didn't see any Forester or any other creatures."

Two Forester Warriors said: "The holy pit emits a powerful aura, and even the evil dragon dares to approach it. Untrue warriors cannot survive in the deep pit. Weak humans and creatures will lose themselves in the holy pit."

Su Yu looked at Captain Phil: "You have a deep study of theology. Can you understand the meaning of this sentence?"

Captain Phil replied: "There must be something under this deep pit, maybe it is some kind of ore that is constantly emitting radiation substances, so it prevents other creatures from approaching, including the Foresters. If they live here for a long time, they will go crazy."

Su Yu and the others were all wearing guard armor. The Wei Guang people were not afraid of any radiation substances. The wounded were recuperating in the underground village of the Forester, so they could go to the deep pit to explore.

Su Yu immediately ordered: "Release the reconnaissance drone."

The Wei Guang Man immediately released the UAV, which flew into the deep pit and continued to go down.

“1000 meters.”

“3000 meters.”

“5000 meters.”

“10,000 meters!”

Everyone was amazed that the depth of the deep pit had exceeded 10,000 meters, but it was still bottomless.

"Reported that the signal of the drone is getting weaker and weaker. If we continue to move down, we may lose the signal of the drone."

Captain Phil immediately touched his chin: "There must be some radioactive material in this deep pit, otherwise it would not be possible to interfere with the unmanned reconnaissance aircraft. Our unmanned reconnaissance aircraft can scan the entire planet at an altitude of 10,000 meters. It is impossible for only 10,000 meters to have no signal."

"That should be the ore that can restrain the Earth-Breaking Dragon. Since we are here, we cannot return empty-handed. We should collect some samples first for analysis." Su Yu said.

Captain Phil sighed: "It's a pity that our dimensional warship has been destroyed and we have no scientific research room."

Su Yu looked at Captain Phil in confusion: "Are you no longer studying basic science? Without a scientific research room, we can make it ourselves."

Captain Phil was startled: "Make it yourself?"

Su Yu smiled: "Of course you can build the laboratory by yourself. Everyone follows my orders, so we will build the experimental equipment first."

Su Yu immediately led everyone to the river to look for silica sand and calcium carbonate-rich stones and shells. Two Forester soldiers watched Su Yu and the others' actions in confusion.

Of course they could not understand what Su Yu and the others did. The holy pit was right in front of them. Why did they dig mud and sand in the river?

But Captain Phil understood at a glance, and he was shocked: "Are you going to make glass?"

Captain Phil is indeed scientifically literate. She saw at a glance that this kind of material that had long been eliminated by them.

Su Yu said: "Yes, transparent glass is a very useful experimental equipment, but your civilization has developed too high, so you may not use this material."

Captain Phil nodded: "Yes, we have a shimmer matrix that can store all matter, so we don't need low-grade materials like glass."

Su Yu had already led everyone to start burning glass, but unfortunately they did not find the bamboo. However, with the help of two forest warriors, they found the vegetation of Zhongtong. Then, Su Yu skillfully blew out the beaker, test tube, and glass cup.

The two Forester soldiers were amazed.

"Shen Falcon Warriors, you are messengers of God, you have divine power!"

Captain Phil smiled and said, "In the early civilization, it was common to regard scientific phenomena as miracles."

Su Yu was not idle. After teaching Wing Monkey to make glass products like this, he began to polish the lenses again. Captain Phil was shocked again: "You want to build a microscope?"

Su Yu said: "With our current technology level, we can only manufacture these equipment, but it is enough."

Captain Phil exclaimed: "It's really not simple. Have you ever been a scientist from scientific research? I really can't tell, I thought you were from the army."

Su Yu said: "To be precise, I was a pilot, but I learned too much in a long time."

At the beginning, I learned to fly a plane, but who knew that I had learned so much messy knowledge in the past few hundred years.

The Wei Guangren was puzzled: "How long are you earthlings' lifespan?"

The primary laboratory was quickly built, and not long after, the primary alchemy kiln was also built. After various iron ores were thrown into the cave, iron tools were also built.

Afterwards, Su Yu and the others officially set off.

"Let's go, we go into the holy pit and extract that special radioactive material."

Su Yu and the others set off immediately, Captain Phil followed closely behind, and two Forester soldiers stopped at the edge of the pit. They knelt on the ground and then kept praying.

"Great Holy Pit, please give us the magical artifact to defeat the evil dragon!"

Su Yu and the others heard the prayer, and then they all looked at each other and smiled. They all remembered the ancient legends in their civilization.

They continued to go deeper, and the Wei Guang Man took out an instrument and began to detect the radiation values ​​around him.

But this instrument did not detect anything, and the radiation in the holy pit was different from any radiation they knew.

Su Yu ordered: "Send unmanned reconnaissance aircraft to build a detection matrix to judge the direction of radiation from the received signals of the drone."

Eight unmanned reconnaissance planes flew out immediately, then occupied eight points to form a cube matrix, and kept distanced from each other.

Subsequently, the low-light man who controlled the drone began to compare the signal volumes of different drones to detect the radiation direction.

Captain Phil said: "I was really eye-opening today. I didn't expect basic science to be so useful. We no longer learn this knowledge because basic labor has been replaced by intelligent robots, and intelligent robots replicate themselves and do not require us to program."

Su Yu paused and then said: "Basic science is still useful when we land on the primitive planet and have nothing on hand. But in general, any civilization will continue to study science and enter the palace of intermediate and advanced science, and handing over cumbersome basic science to robots is also a good choice."

Captain Phil nodded deeply, and she felt that she had learned a lot.

And while they were talking,

The drone matrix has discovered the target, and the semaphore of the unmanned reconnaissance aircraft in one direction has dropped sharply. When the matrix is ​​approaching in which direction, the semaphore of all drones is decreasing.

"Finished!" The glimmer man who was controlling the drone was finally sure, and he shouted excitedly.

Everyone immediately came over, and at this moment, the sky began to get late, and in the direction they were moving, a strange purple light suddenly burst out.
Chapter completed!
