Chapter 424: Underground Pyramid 4

Inside the great hall, because it had lost the command of Sprint.

The several excavation robots and transport robots that had previously dug their way here were now all quietly staying within the great hall, appearing like guards in the vast space.

Of course, that is if one were to ignore the sharp bronze arrows they had triggered that pierced the ground.

Because he was worried that digging directly would affect the load-bearing structure of the Pyramid, Sprint had previously controlled the excavation robots to bypass the top layer and open a hole in one of the side walls, taking a detour before entering.

Therefore, Sun Cheng knew that the great hall they were currently in was not the lowest level of the underground inverted Pyramid they had detected earlier, but the largest great hall at the top.

However, he was in no rush to order the excavation robots to continue digging downward; having just scanned the surroundings, Sun Cheng saw that the walls of the great hall were covered with a large number of murals.

Without needing his order, Mola had already walked quickly toward a wall to study it.

Sun Cheng also felt a bit of interest in this, so he came to a wall of the great hall and began to look as well.

Even though he did not have much understanding of ancient art, he had to admit at this moment that, although the murals on the walls looked far less vibrant in color than those in the ancient Egypt Pyramids, and were not as delicate or rich as the murals of ancient China, these murals, left behind with bold lines and well-coordinated pigments, were truly worthy of being called artistic treasures!

He was, after all, not a person who knew how to appreciate art; after just glancing at the murals for a few moments, he was quickly attracted by the stories depicted on them.

The mural in front of Sun Cheng told the story of a figure who had clearly been mythologized.

The leftmost mural showed an infant floating on a lake; the second mural showed a person dressed as a priest, holding an item imprinted with a Sun brand, seemingly presiding over some kind of ceremony by the lake; then everyone knelt to the infant; the infant was taken by the priest into a palace, and he quickly grew up to become a warrior strong enough to hunt lions and leopards, a great conqueror; he led his own army, holding spears and Shields, wearing battle armor, riding atop tall steeds, and commanded his soldiers to conquer one tribe and power after another...

Sun Cheng did not finish looking at these murals; he had lost interest, and at the same time, he knew that even if he didn't study them, Mola, who was under his command, would carefully check whether any information was hidden within the murals of the great hall.

He then walked away from the wall where he had been standing, walked over to the vicinity of those robots, bent down to pick up an arrow from the ground, and began to examine it carefully.

This great hall, which looked very magnificent and imposing, was clearly not as safe as it appeared.

Otherwise, the excavation robots would not have so many arrows here; it stood to reason that someone must have accidentally triggered some mechanism earlier.

However, these mechanisms, which were extremely dangerous to tomb raiders, posed no threat at all to him and Mola, these two Decepticons.

Even the mass-produced robots in the Base had bodies made of a special steel developed by Decepticon Engineers. Normal 7.62mm rifle bullets manufactured by humans could only leave a very shallow dent on them, let alone these arrows that had been rotting underground for too long.

Therefore, the traps in the great hall naturally could not harm them!

Pinching a slender arrow between his thumb and forefinger and holding it up to his face, Sun Cheng shot a blue light from his left eye and scanned the arrow.

"... Lead-copper alloy... manufactured over three thousand one hundred years ago... a product of the Maya Preclassic period?"

With the Core's scanning function slightly activated, Sun Cheng instantly confirmed that his previous guess was not wrong.

This was an arrow made of lead-copper alloy, which is to say, bronze; although the smelting method was crude, the technology was very mature, and what surprised him most was that the manufacturing history of this thing actually exceeded three thousand years.

Calculated according to the Western calendar, it was manufactured around 1000 BC.

Although he had previously noticed that the Earth in the 【Transformers Universe】, because of the Cybertronians, had a historical trajectory that seemed generally the same as the real world he was born in, from a fundamental perspective, it already had essential differences.

The Maya, who should have belonged to a Stone Age civilization, somehow managed to produce bronze in the Preclassic period around 1000 BC, and the technology was supposedly very mature, still retaining lethality to this day.

"Snap!"

He quickly threw the arrow aside and glanced at Mola. Seeing that Mola had walked to another wall at some point and was currently emitting a large amount of heat as if he had just finished a sauna, Sun Cheng did not rush to ask if the other party had discovered anything.

He simply wandered around the relatively empty great hall and, by the way, activated his scanning mode to find the passage leading downward.

"Clatter-clatter-clatter!"

One trap after another was triggered one by one under his indifference; the dense bronze arrows, as numerous as cow hair, hit his body with a clatter like rain, unable to even leave a white mark before breaking and falling into the great hall.

"Crash!"

The deep pit that suddenly opened in the ground could not contain his massive body at all; he simply let his feet easily crush those bronze spikes and then climbed out of the trap.

The sprayed unknown gas was dispersed by a wave of his hand, the vent pouring sand into the great hall was smashed with a single punch, and also smashed was the giant stone ball that had suddenly rushed out from behind a fake door he had triggered.

All the oddities in the great hall were soon destroyed or resolved under the scan of his eyes, and Sun Cheng finally found the correct passage leading downward.

However, when he used brute force to lift the giant stone weighing several tons and violently opened the passage to the next level, he quickly frowned.

As far as his sight could reach, it was a passage no more than ten meters long, yet it was a passage that only allowed humans to pass through.

That's right, it looked to be less than one point five meters high; even a human would have to bend over to move forward, let alone someone of his bulk.

As far as his sight could reach, no patterns or murals could be seen inside the passage, and Sun Cheng immediately had an idea.

He was just about to order Sprint to continue commanding the excavation robots to dig out a passage that would allow him to pass as soon as possible.

Just at this moment, Mola, who had been studying the murals in the great hall for a long time, suddenly shouted excitedly.

"Master, please come over and see what I have discovered!"

"Hmm?"

Sun Cheng walked over with some surprise and, following the finger of Mola—whose artificial skin on his arm was also beginning to wrinkle—looked at a mural in front of him.

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