As soon as they entered the channel broken by their own plasma gun, sun Cheng and they immediately saw a more tragic battle in the past than before.


    Wreckage!


    Debris everywhere!


    On the original ground of the passage, the remains of countless incomplete Cybertron people and primitive beasts are everywhere.


    "The battle before ancient times was really terrible!"


    What he saw in front of him also made sun Cheng reach out and gently touch his body''s chest.


    As like as two peas of a claw as like as two peas, the same remains of the same body.


    It is said that there were six ancestors of the former Cybertron, who chose to sacrifice their lives to create a tomb that could never be found in order to protect the [leadership module] and ensure that the precious treasure would not be taken away by the Fallen King Kong.


    That was the last time sun Cheng was away from death. Even he felt that facing death there was closer than facing the Fallen King.


    To this end, he left this wound in order not to forget his original feeling.


    Sun Cheng never doubted the power of Yuanzu, but the original Yuanzu were obviously not at their peak.


    Therefore, he always lacks some clearer understanding of how powerful Yuanzu should be in the peak period.


    Here, although there is no sign to prove that emperor maxim, one of the thirteen ancestors of Cybertron, personally took action.


    But the remains of this place, only from the point of view of the body, the incoming Cybertron soldiers were not short of elite and powerful soldiers.


    Many of them looked like being killed by a second blow from the wound. This discovery made him wonder whether emperor Maxim himself had done it at the beginning.


    This passage is not as deep as the previous one. After traveling hundreds of meters, you can see an alloy door with a huge gap blown out by energy weapons.


    Sun Cheng stepped forward and tapped his finger on the small broken door left by the alloy door.


    In an instant, it was corroded by extreme cold and freezing all year round. It was also like an ice block, which easily broke up.


    He looked up and saw a huge alloy door more than 30 meters high in front of him. Sun Cheng clenched his weapon and immediately walked in without hesitation.


    After entering the alloy door from the gap, you can see a damaged and shapeless space.


    This is a space of 70000 square meters, far less spacious than the underground space outside.


    However, under the thick ice crystals here, in addition to the debris, many strange machines can be seen.


    "Maxim the Great''s Laboratory..."


    Sun Cheng''s eyes brightened, but soon they darkened again.


    Through the ice, you can vaguely see that almost all equipment has been artificially damaged.


    Moreover, even if all the equipment here are intact and have been frozen for countless years, under the severe cold corrosion, the machines here can''t be used again unless they are thawed by some special means.


    Sun Cheng and his Decepticon engineers don''t have that special thawing technology for the time being.


    "It seems difficult to pick up the leak from here!"


    Several Decepticons soldiers carefully inspected the underground space of the suspected research room for a while, and reluctantly returned to report to him.


    "Commander, I didn''t find any other entrance. This is the end!"


    Sun Cheng nodded. After looking around again, he turned and walked through the passage.


    Cybertron people are a very contradictory race. They can create a great city like Ironforge and design a series of passes and fortresses.


    But most of the time, cybertans are pragmatists.


    For example, the laboratory built by Maxim the great, although it seems to human beings, has amazing quantities. It is not only located deep underground, but also dug out several large underground spaces.


    However, this underground laboratory has no sense of beauty or construction art, and is far inferior to the various scientific research laboratories everywhere during the Senate of Cybertron in the memory of Skyfire.


    This feeling was maintained until sun Cheng returned to the previous underground space and used a plasma gun to blast open another artificially collapsed channel.


    Lead the team again, ready to explore the remaining channel.


    Sun Cheng just blasted away the collapse at the entrance of the passage and noticed the abnormality a few steps forward.


    The core of the body suddenly issued a warning, and the fire burned violently and autonomously.


    "Stop, all Decepticons retreat!"


    He looked down at the ice that began to condense quickly on the body, and sun Cheng''s face changed suddenly.


    The temperature dropped too fast. Not long after he stepped into this channel, he felt that the surrounding temperature dropped rapidly. It hardly took him long to break through minus 80 degrees, and it was still falling.


    At this temperature, even the Decepticon senior soldiers can''t stand it.


    If they continue to move forward, they must always consume the energy in the fire to create heat and maintain the body.


    When sun Cheng found out, the other Decepticons who were about to follow him to explore the channel also noticed the change.


    Watching the body freeze a little bit, that feeling is very bad.


    Therefore, after receiving his order, all Decepticons immediately withdrew and withdrew from the channel.


    Sun Cheng himself continued to go deep into the channel with the courage of art experts.


    This passage is obviously much longer than the other one next to the laboratory.


    However, sun Cheng walked very fast, because although his body was also strengthened for the harsh environment, it was not unaffected at all.


    This passage was more seriously damaged than the one next to it. From time to time, you can see a collapse, all of which were directly blasted by him with a plasma gun.


    After traveling more than two kilometers obliquely downward, another damaged alloy door appeared in sun Cheng''s vision.


    The big hole that was broken from the alloy door was blocked by ice.


    Sun Cheng raised the plasma gun and aimed it at the gap.


    Along with the ice chips splashing everywhere, an ice hole for him to pass suddenly appeared on the alloy door that had been frozen.


    Sun Cheng tightened his weapon and quickly went through the hole to enter.


    The next moment, he just felt a flash in front of him.


    How big!


    What you see is a huge underground space as if you were looking at it. The space is not dark. There are more luminous microorganisms that appeared in the above underground space.


    They are flickering in many icicles and ice walls in this huge underground space. Thanks to this, sun Cheng can see things close to him without special electromagnetic wave detection.


    Tens of meters in front of the alloy door, there is a huge ice lake like a flat mirror.


    Sun Cheng came closer and subconsciously looked at the ice lake.


    The next moment, he clenched the plasma gun in his hand.


    Under the ice, there are a pair of huge and empty eyes, which look strange and ferocious!
