Since he had noticed that a spaceship from Cybertron might have fallen near here before ancient times, sun Cheng couldn''t resist it. He immediately called Mora and asked what clues he could get from these murals in the hall.


    "... master, there are only murals in this hall without any words... The murals on this wall are suspected to tell that a Decepticon once came to the earth. He was regarded as a God by the ancient Indians who were still in the wild era at that time. It seems that he finally lived here..."


    "Here is the Decepticon. The professor taught human astronomy, writing, calendar and system... Helped them jump from the stone age to bronze civilization..."


    "Here is a story about a human being born from a lake who became the new leader of the ancient Indian tribe under the protection of the Decepticon... Under the command of the young leader, they defeated and annexed countless tribes, captured many slaves, enslaved the defeated and built cities and temples for them... Among them, the underground pyramid under our feet , the sleeping place built under his command for the Decepticon... "


    There are murals on only three walls of the hall, so it happens that there are three groups of stories separately, so Mora can only interpret three paragraphs.


    In this regard, sun Cheng''s eyebrows were a little agitated, but he didn''t get nothing at all.


    At least he knew a few things. About 3000 years ago, a Decepticon came to America and taught a lot of knowledge to the ancient Indians who were still in the wilderness at that time.


    The Mayan civilization on earth in this world was born by the Decepticon. Although it solved many doubts in his heart, this is not a good answer.


    Because the Mayan civilization is slavery, and the Decepticons'' attitude towards mankind is basically no different from that of the cheapest labourers and slaves.


    So he is not sure whether the other party is a pathfinder or not.


    Don''t underestimate the word Pathfinder. Having it means that the possibility of an ark class spacecraft here will be raised infinitely.


    Although sun Cheng had no personal contact with the spaceship made by the cybertans, it is not difficult to infer from the murals that the spaceship may have been damaged.


    However, the pinnacle of Cybertron civilization is not so easy to break down.


    As long as we don''t encounter the cosmic rust that can''t be defended at all, even if the body of ordinary Decepticons is thrown into the earth''s ocean, it will take hundreds of years to be completely corroded. Moreover, the more powerful Decepticons are in life, the slower they will be corroded after death.


    That''s why Sun Cheng was still so excited when he learned that there might be a falling spacecraft here.


    Because he knew very well that it was absolutely impossible to completely destroy a spaceship made at the peak of Cybertron civilization in just 3000 years on earth.


    Even if he could only get some fragments and parts from the wreckage, it would be a great harvest. If he was lucky enough to get the control computer and power system of the spacecraft, it would be a worthwhile trip.


    As for whether there is the remains of a pathfinder buried in the underground pyramid, sun Cheng really doesn''t have much expectation.


    It is said that pathfinders are the best soldiers in Cybertron. Most of them are arrogant. When their lives come to an end, few people will choose to sleep and wait for the rescue of people who may wait in the future.


    Like the [monster general] he once contacted in Lop Nur, when his life came to an end, he silently detonated his dying fire without leaving his remains.


    Therefore, the possibility of finding the wreckage of the ship here is much higher than that of getting the remains of a Pathfinder.


    "There seems to be nothing on this floor..."


    Sun Cheng said in a deep voice that he had just used his detection function to trigger all the mechanisms in the hall, and he found the aisle leading to the lower floor. However, the passage is only about ten meters high, or even less than one meter and five meters high. Even humans can only bend forward, let alone a big man like him.


    Moreover, there are no patterns or murals in the channel. At present, he no longer hesitates. Sun Cheng knows that he must pay attention to it all the time when he is sprinting outside.


    So he just whispered an order: "sprint, let the machine people move immediately. I want to see the passage to the next floor as soon as possible!"


    As soon as the sound fell, the twelve robots in the hall, which had been silent like guards, shook together and soon began to work.


    He didn''t have to wait long. It took him less than forty minutes.


    Based on the channel he found, they dug a tunnel that they could pass through.


    Then sun Cheng was disappointed when they entered the next floor of the underground pyramid again.


    "Master... This is a place for burial and sacrifice..."


    The second floor of the underground pyramid is different from the upper floor. It is composed of four separated spaces, namely, the tomb area where ancient Indian Kings, gods and nobles are buried; A voluntary burial area composed of ancient Indian warriors; A burial pit where prisoners and slaves are slaughtered; There are also sacrificial pits for all kinds of livestock.


    Sun Cheng was annoyed by the white bones. He turned a little and ordered him to continue digging downward.


    To his surprise, this time he waited for more than three hours. The lower two floors were all maze like anti-theft areas composed of various hidden channels.


    As a result, the excavation robot had to dig through the two-story anti-theft area at one go, and sun Cheng came to the bottom of the underground pyramid.


    "Bang!"


    Sun Cheng jumped from the mouth of the cave where earth and rock were still falling down and came to the bottom of the underground pyramid, a very narrow space.


    This is probably the underground pyramid that is the ancestor of all the Mayan pyramids in the world. Although it is an inverted pyramid, it also has roughly the same structure as those Mayan pyramids on the surface.


    Therefore, the floor [Temple] where they are now should be the place in the mural to bury the Decepticon skeleton of the suspected Pathfinder.


    After reaching out half way, he touched the top of the space and felt that earth and rock were falling on his body. Sun Cheng shook his head. He didn''t like this feeling.


    However, when he looked around, he saw everything in the narrow temple, which was no more than six meters high and only 15 meters long and wide.


    The expression on his face changed in an instant!


    "Corpse?!"


    In the middle of the temple, two meters behind the cave where he jumped down, there was a huge gold ship suspected of being watered with gold. On the ship, a ferocious giant with all kinds of terrible wounds and rust was lying quietly.


    On the giant''s chest, a mark that sun Cheng knew could no longer be familiar with seemed to twinkle with a faint fluorescence in the dark.


    How could he not have imagined that he could really find the remains of a pathfinder in the temple at the bottom of the underground pyramid!

    With another word of humility, something happened to my shop and I was busy for a few days.
