Taking the place where the "speed of light crystal" fell and the Pangu tribe appeared as the center of the circle, Lee launched a search with a radius of more than 100 kilometers.

Sure enough, when he discovered the mystery hidden under the vines, weeds and fungus blanket, and constantly sent out flames to burn, he found many wrecks of star ships under the lush vegetation.

Qinglong, Changkong tiger, golden Warhammer, jiutoulong... Are all terrain warships that can freely shuttle through gravity free vacuum and high gravity atmosphere.

Like the speed of light crystal, these warships turned into twisted wrecks and were engulfed by crazy plants. There were not many valuable discoveries in them.

However, Li Yao found a large number of scattered skeletons near the wreckage of these warships - several meters long, thick and powerful dark gold thigh bones, which obviously came from the Pangu people, not humans.

Perhaps, there were a lot of human corpses here, but they were engulfed by plants and fungus blanket just like the flesh and blood of Pangu people. Only these golden thighbones, which are the thickest and strongest, and can bear dozens of tons of weight, can be indelible.

Therefore, when Ding lingdang, long Yangjun and Li Linghai's leading human exploration fleet entered the emperor's tomb, the first encounter was not LV Qingchen's ambush, but a large group of crazy Pangu people?

Li Yao carefully examined the damage condition of every wreck of the starship, never let go of every trace, and deduced the cause of the trauma with his rich experience in refining weapons.

He found that the vast majority of seemingly shocking scars came from very low-level individual magic weapons, such as oversized chainsaw sword and concussion saber.

Even around some irregular cracks, there are some dark golden bloodstains, which seem to have been torn by the Pangu people with their bare hands. It is quite in line with the characteristics of the Pangu people who just drank blood and had boundless brute force.

If it is an organized Pangu fighting team, it should not only carry individual magic weapons such as chainsaw sword and concussion sword, or even use fists against human warships without magic weapons.

Therefore, Li Yao suspected that the Pangu people encountered by the human exploration fleet, just like the Pangu people just now, had lost their memory and reason and degenerated into barbarians with only ignorant instincts.

Is this the role of "virus" in long Yangjun's mouth, or the role of "light of life" that can thaw time and promote the crazy growth of plants, or is it the result of millions of mutations of the virus in an instant under the stimulation of "light of life"?

Lee did not know.

Although he was very anxious and wanted to find out the answer in the next second, he managed to suppress his anxiety and found all the crashed starships within a radius of two or three hundred kilometers. From these wrecks, he collected just enough magic weapon components, high-energy nutrients and crystal fuel.

He was lucky that the maintenance workshop of a multi-functional support ship was basically intact, and the maintenance platform was still available.

Although it is impossible to transform the giant warrior, fortunately, the main structure of the "arsonist" has not been destroyed, but the shell has been torn apart by the meteorite storm of "Gu 13".

After replacing a reactive armor, adding hundreds of colorful metal patches and filling it with crystal fuel, it ignited a dark and stubborn flame.

Before finally marching towards the "origin", Lee had a night off.

As like as two peas in the imperial tomb, there was no real day and night. After the blue sky and white clouds lasted for about an hour, the sky was enveloped in dense fog. The process lasted for nearly ten hours, and then it was a new blue sky and white cloud that was exactly like yesterday. It was a new day, and the sky was white and white. The clouds were white and white. The whole sky was covered with dense fog. The process lasted for nearly ten hours. Then, the sky and white clouds were identical.

Li Yaoyin has a feeling.

This ancient relic, no matter it is called "emperor's ancient tomb" or "God's tomb" or "black tomb", is not for Pangu people, but for human beings.

The reason is obvious.

The gravity here is the standard gravity most suitable for human survival and fighting. So is the oxygen and various impurities in the air, including temperature, humidity, and even plants, animals and fungi.

Li Yao detected the toxicity of many kinds of plants, animals and fungi, and found that most of the creatures here are not toxic, but have excellent supplement and recovery effects on the human body. It's a "blessed place" with "natural resources and local treasures" everywhere.

Even if ordinary people live a life of drinking blood, eat a lot of natural resources and land treasures, and breathe the freshest air, they will gradually grow their flesh and blood, wake up their spiritual roots, and become cultivators.

In addition, the "day and night" of nearly 24 hours is also the most suitable "standard planet" for human survival, and the most average rotation time.

For example, Pangu, a giant that needs cold air and low gravity, because the density of the original planet is small, the volume is often large, and the rotation cycle will be longer. Their "day and night" is far more than 24 hours.

Pangu people will not be too comfortable here.

"Why?"

Li Yaonan said to himself, "if this is really the" control hub "of black wall makers, why is it so suitable for human survival and cultivation? What is the so-called "black wall maker"

The answer to this question, like countless questions just now, will not be revealed until Li Yao arrives at the real entrance of the ancient tomb.

Li Yao released Xiaohei while he was recuperating his energy. Through it, he controlled and monitored the crystal eye, scanned the terrain of 500 kilometers nearby, eliminated the interference of towering trees and fungi and weeds, and compared it with the topographic maps drawn in previous exploration of Li Linghai.

As expected, the "origin" with the strongest "light of life" and the most dense plants is the real entrance of the ancient tomb.

When the sky was once again smeared with a strong blue, Li Yao opened the way with a fire saber and marched towards the deepest part of the jungle.

A large number of plants and fungi make a "squeak" sound in the burning flame, shivering and spreading, but more branches and vines rush to the ashes behind Li Yao, devouring his way instantly.

The nightmarish scene can't stop Lee's determination to explore the truth. He trudged in the jungle. Three hours later, after discovering more starship wrecks, he finally found a camp site left by Li Ling's second exploration on the sea!

This is a fragment of the metal radiation proof tent. The word "deep sea" is left in one corner of the fragment.

This kind of tent is used to build a mobile laboratory, which can isolate all kinds of subtle radiation and ensure the accuracy of the experimental results. Li Linghai told Li Yao that she had tried to carry out some research in the emperor's tomb, so that she carried and carried out a large number of tents.

The word "deep sea" naturally means deep sea fleet, and it is the private arm of Li Linghai.

Having said that, Li Linghai didn't want too many people to know such a big secret of the emperor's ancient tomb, so every time she explored, she almost only carried a large number of psionic puppets as assistants.

When Li Yao dug out the abandoned multi-functional puppets of Santai from the depths of the earth, as well as a large number of fragments of the engineering magic weapons of the era of Xinghai Empire, he strengthened his judgment. This is Li Linghai's camp, the emperor's forward base, and the real entrance to the emperor's ancient tomb.

What about the "door"?

Li Linghai told Li Yao that there was a literal "gate" at the real entrance to the imperial tomb.

It was a black stone tablet nine meters high, four meters wide and one meter thick.

The square ratio of nine to four to one and three to two to one is very solemn and perfect.

This gate, or the black stone tablet, is as accurate as the first entrance. No matter how precise measuring instruments Li Linghai uses, he can't calculate even a tiny error. He has reached the peak in the fields of mechanics, materials science and finishing.

However, the first entrance is open to all. As soon as any living creature touches it, it will be assimilated, fused and inhaled by it. The second entrance is a very solid black stone tablet. No matter what method Li Linghai uses to stimulate it and collide with it, he can't open it.

If not for a few words of information from the emperor's forward base, and Wu Yingqi, the black star emperor, firmly believed that it was the real entrance, Li Linghai could not connect a solid stone tablet with the gate to the ancient mystery.

The existence of this black stone tablet also confirmed Li Yao's conjecture that "Archean relics are prepared for human beings".

The gate, which is nine meters high and four meters wide, is too cramped for the Pangu people, or for the Pangu people who are as tall as 10 meters.

For human beings, the two conflicting concepts of solemnity and delicacy are well integrated.

What's more, the "meter" is originally the most suitable length unit for human beings. When any kind of humanoid intelligent life sets its length unit, it is often the first to think of its own arm length. Therefore, the "meter" of Pangu is much longer than that of human beings.

"In the Archean era hundreds of millions of years ago, there was a certain kind of super civilization, with" meter "as the unit, leaving a door to the future for mankind hundreds of millions of years later?"

Li Yao thought so.

But now, the gate is gone.

Li Linghai told Li Yao that her camp and the emperor's forward base were set in front of the black stone tablet, and the distance between them would not exceed 100 meters. Within a radius of 100 meters, no matter how high the weeds and shrubs grew, Li Yao would not ignore a nine meter high black stone tablet.

But

Li Yao let out his mind and scanned towards the direction where the black stone tablet should exist. Suddenly, his heart beat faster. A "buzzing" sound sounded in his mind, as if it were a chant from archaic times, a call of incomparable holiness and mystery.

"What the hell is this?"

Looking at the latest form of the black stone tablet close at hand, Li Yaomu was stunned and lost his voice.
