Taking the fall of the "Light Speed ​​Crystal" and the appearance of the Pangu tribe as the center, Li Yao launched a search with a radius of more than 100 kilometers.

Sure enough, when he discovered the mystery hidden under vines, weeds and fungi blankets and kept releasing flames to burn them, he found many wreckages of starships under the lush and living vegetation.

The Blue Dragon, the Tiger in the Sky, the Golden Warhammer, the Nine-Headed Dragon... are all all-terrain warships that can freely shuttle through the gravity-free vacuum and high gravity atmosphere.

Like the "Crystal of Light", these warships turned into twisted wreckage and were swallowed by crazy-growing plants, and there were not many valuable discoveries in them.

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

Perhaps, there were also a large number of human corpses here, but like the flesh and blood of the Pangu tribe, they were swallowed by plants and fungi blankets. Only these thickest and most sturdy golden thigh bones that could carry dozens of tons of weight could be difficult to erase.

So, when Ding Lingdang, Long Yangjun and Li Linghai's leading human exploration fleet entered the Emperor's ancient tomb, the first thing they encountered was not Lu Qingchen's ambush, but a large group of Pangu tribes who were crazy?

Li Yao carefully examined the damage of each starship wreckage, not letting go of every clue, and used his rich experience in refining the cause of the trauma.

He found that most of the seemingly shocking scars came from very low-level individual weapons such as extra-large chainsaw swords and shock swords.

Even around the irregular cracks, there were some dark golden blood stains, which seemed to be torn apart by the Pangu tribe's bare hands and forced torn apart, which was very consistent with the Pangu tribe's characteristics just now, who had ate raw blood and drank endless brute force.

If it is a Pangu combat team that is established, it should not only carry individual magic weapons such as chain saw swords and shock swords, and even magic weapons. It doesn't even need magic weapons, but uses its fists to fight against human warships.

Therefore, Li Yao suspected that the Pangu tribe encountered by the human exploration fleet had lost memory and reason, just like the Pangu tribe just now, and degenerated into a barbarian with only ignorant instinct.

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

Li Yao didn't know.

Although he was anxious and wanted to reveal the answer in the next second, he still barely suppressed his anxiety and found all the crashed starships within a radius of two or three hundred kilometers. From the wreckage of these starships, he collected barely enough magic weapons, high-energy nutrients and crystalline fuel.

He was lucky. The maintenance workshop with a multi-function support ship was generally kept intact and the maintenance platform was also available.

Although it is impossible to transform the giant god weapon, fortunately, the main structure of the "Arsonist" has not been destroyed, and it was just torn apart by the "Ancient Thirteen" meteorite storm.

After replacing a reflex armor, hundreds of colorful metal patches were applied, and filled with crystal fuel, it ignited a dark and stubborn flame.

Before marching towards the "original point", Li Yao rested for a night.

There is no real day and night in the tomb of the Emperor. After the blue sky and white clouds lasted for about fourteen or five hours, the sky was shrouded in a strong fog. This process lasted for nearly ten hours, and then it was new, the blue sky and white clouds that were exactly the same as "yesterday".

Li Yao had a faint feeling.

This ancient ruin, whether it is called the "Emperor's Ancient Tomb", "Divine Tomb" or "Black Tomb", was not prepared for the Pangu tribe, but for humans.

The reason is obvious.

Gravity here is the standard gravity that is most suitable for human survival and combat. The same is true for the oxygen and various impurities in the air, including temperature, humidity, and even plants, animals and fungi.

Li Yao tested the toxicity of many types of plants, animals and fungi, and found that most of the creatures here are not only not toxic, but have excellent supplement and recovery effects on the human body. It is simply a "blessed land of heaven and earth" and "good treasures of heaven and earth" can be seen everywhere.

Even ordinary people live a life of eating raw meat and drinking blood here, eating a lot of treasures, and breathing the freshest air, and then gradually strengthening flesh and blood without a teacher, awakening their spiritual roots, and becoming practitioners.

Also, the "one day and night" that is nearly twenty-four hours is also the "standard planet" that is most suitable for human survival, and the most average rotation time.

Such as the Pangu people, who require cold air and low gravity, are because the native planets have smaller density and large volumes, and their rotation cycle will be longer. Their "day and night" far exceeds twenty-four hours.

The Pangu people will never feel comfortable here.

"Why?"

Li Yao murmured to himself, "If this is really the 'control hub' of the black wall maker, why is it so suitable for human survival and cultivation? What does the so-called 'black wall maker' look like!"

The answer to this question, like the countless questions just now, will have to wait until Li Yao arrives at the real entrance to the ancient tomb before it can be revealed.

While raising energy, Li Yao released Xiao Hei, manipulated the surveillance crystal eye through it, scanned the nearby 500 kilometers of terrain, eliminated the interference of towering trees and fungal weeds, and compared it with the topographic map drawn in the previous explorations of Li Linghai.

As expected, the "light of life" is the strongest and the "origin" with the densest plants is the real entrance to the tomb.

When a strong blue was applied to the horizon again, Li Yao used the flame sword to open the way and marched towards the deepest part of the jungle.

A large number of plants and fungi made a "squeaking" sound during the burning of flames, shaking and dispersing, while more branches and vines rushed towards the ashes behind Li Yao, instantly swallowing his origin.

The nightmare-like picture could not stop Li Yao from exploring the truth. He trekked hard in the depths of the jungle. After three hours, after discovering more starship wreckage, he finally found a camp ruin left by Li Linghai during his last exploration!

This is a fragment of the metal radiation-proof tent, with mottled words "deep sea" remaining in one corner.

This tent is used to build a mobile laboratory, which can isolate various 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 tomb of the emperor, so she carried and unfolded a large number of tents.

The word "deep sea" naturally means the deep sea fleet, which is the private armed forces of Li Linghai.

Having said that, Li Linghai didn't want too many people to know about the 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 three multi-functional puppets that had long been abandoned from the depths of the soil, and a large number of fragments of engineering magic weapons in the Xinghai Empire era, he became more determined to make his judgment. This is Li Linghai's camp, the emperor's advance base, and the real entrance to the emperor's ancient tomb.

So, what about the "door"?

Li Linghai told Li Yao that the real entrance to the Emperor’s ancient tomb has a literal "gate".

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

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

This gate or this black stone tablet is the same as the first entrance, and is also extremely accurate. No matter how fine the measuring instruments Li Linghai uses, he cannot calculate even a slight error. It has reached its peak in the fields of mechanics, materials science and finishing.

However, the first entrance is unavoidable. When any creature touches it, it will be assimilated, fused and sucked in. The second door is an extremely strong black stone tablet. No matter how Li Linghai uses to stimulate it or collide it, it cannot open it at all.

If it weren't for the fact that he had obtained a few words from the Emperor's advance base, and the Black Star Emperor Wu Yingqi also firmly believed that it was the real entrance, Li Linghai really could not connect a solid stone tablet with the gate leading to the ancient mystery.

The existence of this black stone tablet also strengthened Li Yao's speculation that "the ancient ruins are prepared for humans."

The gate, which is nine meters high and four meters wide, is too cramped for the Pangu tribe, or the giants who are more than ten meters tall, just like the Pangu tribe.

For humans, the two conflicting concepts of solemnity and exquisiteness are just right.

What's more, the length unit of "meter" is originally the most suitable for humans to use any human-shaped intelligent life. When setting the length unit, they often think of their arm length first. Therefore, the Pangu tribe's "one meter" is much longer than the human "one meter".

"Did there be some kind of super civilization in the ancient times billions of years ago, in units of 'meter', leaving a door to the future for humans billions of years later?"

Li Yao thought so.

But now, the door is gone.

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

But……

Li Yao released his divine thoughts and scanned in the direction where the black stone tablet should exist. His heartbeat suddenly accelerated, and a "buzzing" sound rang out in his mind, as if it was a chanting from the ancient times, an extremely sacred and mysterious summoning.

"What the hell is this!"

Looking at the latest form of the black stone tablet, Li Yao was stunned and shouted in dismay.
Chapter completed!
