In the main hall, because of the loss of command of the sprint.

The excavation robots and transport robots that had been excavated here before were all quietly staying in the main hall at the moment, as if they were guards in the huge hall.

Of course, if you ignore some of the sharp bronze arrows that their guards have pierced the ground.

Because I was worried that the direct excavation would affect the load-bearing structure of the pyramid, I controlled the excavation robot to bypass the top floor and cut a hole in one side of the wall, and went around one more time before entering.

Therefore, Sun Cheng knew that the hall they were in now was not the lowest level of the underground inverted pyramid that they had detected before, but the largest hall at the top.

However, he was not in a hurry to order the excavation robot to continue excavating, just now he looked around, and Sun Cheng saw a large number of murals painted on the walls around the main hall.

Without his orders, Mora had already walked briskly to a wall and studied.

And Sun Cheng was also a little interested in this, and when he came to one of the walls of the main hall, he also looked at it.

Even though he didn't know much about ancient art, he had to admit that although the murals on the walls looked far less colorful than the murals in the pyramids of ancient Egypt, nor as delicate and plump as the murals in ancient China, the murals left by the rough lines and well-matched pigments were indeed artistic treasures!

He was not a person who knew how to appreciate art, but he just looked at the mural a few times, and was soon attracted by the story on the mural.

The mural in front of Sun Cheng tells the story of a character who has been clearly mythologized.

a mural on the far left showing a baby floating above a lake; The second mural shows a man holding a sacrificial figure imprinted with the imprint of the sun on the lake, as if he is presiding over a festival; Then everyone bowed down to the baby; The infant was sacrificed to a palace, and he soon grew up and became a warrior strong enough to hunt lions and leopards, a great conqueror; He commanded his army, armed with spears and shields, dressed in battle armor, and mounted on tall horses, and commanded his soldiers to conquer one tribe after another......

Sun Cheng didn't finish reading these murals, he was not interested, and at the same time, he knew that even if he didn't study them, his subordinate Mora would carefully check whether there was any information hidden in the murals in the main hall.

He walked away from the wall where he had been standing, and walked over to the robots, stooped down and picked up an arrow from the ground, and examined it carefully.

In this magnificent-looking hall, it is clearly not as safe as it seems.

Otherwise, the digging robots wouldn't have so many arrows here, and someone must have accidentally triggered some mechanism before they came.

However, these traps are extremely dangerous for the tomb robbers, and not only are they no threat to him and Mora, the two Decepticons.

It is the robots mass-produced in the base, and their bodies are also made of a special steel developed by Decepticon engineers. Ordinary human-made medium-caliber 7.62mm rifle bullets can only leave a shallow dent on them, let alone these arrows that have been rotting in the ground for too long.

Therefore, some traps in the main hall naturally could not hurt them!

His thumb and index finger pinched a slender arrow and held it up in front of him, and Sun Cheng shot a blue light from his left eye, and glanced at the arrow.

“…… Lead-copper alloy ...... It has been manufactured for more than 3,100 years...... Is it a product of the Pre-Classical Mayan period......"

The core probing function was slightly turned on, and in an instant, Sun Cheng was sure that his previous guess was not wrong.

This is an arrow made of lead-copper alloy, the so-called bronze, although the smelting method is rough but the technology is very mature, the most surprising thing to him is that this thing has been manufactured for more than 3,000 years.

According to the Western calendar, it was made around the first millennium BC.

Although he had also noticed before that the earth in the [Transformers Universe], because of the relationship between the Cybertrons, the historical direction seemed to be roughly the same as the real world he was born in, but fundamentally, there was an essential difference.

The Maya, which should have belonged to the stone civilization, were able to make bronze in the pre-classical period before the first millennium BC, and the technology was very mature, and it is still lethal to this day.

"Smack!"

Quickly throwing the arrow aside, Sun Cheng glanced at Mora, and saw that he didn't know when he had walked to the other wall, and at this moment, a lot of heat was coming out of his whole body as if he had just finished taking a sauna, and he didn't rush to ask the other party if he had researched anything.

He simply wandered around in this relatively empty hall, and by the way, he turned on the scanning mode, and instantly led to the passage below.

"Bang Bang!"

One trap after another was triggered one by one under his uncontrollability, and the dense bronze arrows like cow's hair continued to crackle and hit his body like rain, and even a white mark could not be left before breaking and falling in the main hall.

"Whoa!"

The deep pit that suddenly sank into the ground could not contain his huge body at all, so he could only let Sun Cheng's feet easily crush those bronze spikes before crawling out of the trap.

The unknown gas sprayed was dispersed by him with a wave of his hand, and the spout that poured sand into the main hall was shattered with a single punch, as was the huge stone ball that suddenly appeared from behind the false door opened by his attack.

All the oddities in the main hall were quickly destroyed or punished under the scanning of his eyes, and Sun Cheng finally found a proper passage to the bottom.

It's just that when he lifted the boulder weighing several tons with brute force and violently opened the passage to the next floor, he quickly frowned.

As far as the eye can see, it is a passage that is no more than ten meters long, but this is a passage that can only be passed by humans.

That's right, it looks less than a meter and a half tall, and even a human can only bend forward, let alone a big guy like him.

As far as the eye could see, there were no patterns or murals in the passage, and Sun Cheng suddenly had a number in his heart.

Just about to give the order to sprint, let him continue to direct the digging robots to dig a passage that they can pass through as soon as possible.

At this moment, Mora, who had been studying the mural for half a time in the main hall, suddenly shouted excitedly.

"Master, please come and see what I found!"

"Huh?"

Sun Cheng walked over with some surprise, and looked at a mural in front of him along the fingers of Mora, whose artificial skin on his arm had also begun to wrinkle.

The moment his eyes saw the mural clearly, his right fist clenched violently, and he let out an exclamation: "Ark?!" ”
