I can't help but feel a little disappointed!

Sun Cheng looked back at the boulder carefully, and was about to withdraw the battle robot and prepare to leave.

The moment he turned around, a flash of inspiration flashed in his mind: "Granite boulder...... Wait a minute...... Damn it, such a simple cover-up, even I was almost deceived......"

Although this Lop Nur is not the desert it is today, it may have been a river and grassland with fertile water and soil a long time ago.

However, Sun Cheng can be sure of one thing, the geological structure in this vicinity is absolutely impossible to naturally give birth to such a large piece of granite.

Yes!

The Lop Nur area has not produced granite since ancient times, and now the boulder in front of him looks very suspicious!

It was either transported from afar by the Decepticons or Autobot Pathfinders a long time ago, or it was carried by humans who worshipped them as gods.

But no matter who got it, there is no doubt that there is one thing that proves one thing, there must be a reason behind this granite that will be carried here from afar!

At that moment, he dismissed the idea of leaving, and rejoined the boulder, staring at it and examining it carefully.

It didn't matter if he looked at it, Sun Cheng quickly noticed something strange.

"Sure enough, there's weirdness!"

There was a flash of excitement in his eyes, and he stared at the boulder in front of him, and the corners of his mouth finally had a smile.

From a human point of view, it is naturally difficult to detect that something is wrong with this boulder.

However, since Sun Cheng realized that there was something wrong with the boulder, the scanning electromagnetic waves emitted by his body never stopped, and he continued to penetrate and scan the boulder in an attempt to find the problem.

He had thought that the Pathfinders from Cybertron had used boulders to hide the entrance to a cavern or some base.

Who would have thought that even if the electromagnetic waves penetrated to an extreme depth of tens of meters underground, they did not find any caves or anything like that.

Instead, inside the boulder, it was as if something was interfering with his electromagnetic scanning.

The electromagnetic waves emanating from his core could not penetrate the boulder!

"There's something in the stone, but what is it?"

When you come to the boulder, reach out and gently brush it over the smoother surface of the boulder, which is obviously polished.

Sun Cheng hesitated for a moment, but he still couldn't hold back the curiosity in his heart.

So, he threw a punch at the boulder and slammed it in.

"Bang!"

The metal fist forged from alloy landed heavily on the boulder with a dull crashing sound, and several pieces of small broken stones fell immediately from the place where his fist hit the boulder.

Sun Cheng quickly withdrew his fist, frowned and glanced at the boulder with only a shallow fist mark on it, as well as a dozen or so small cracks, and couldn't help muttering: "It's quite hard!" ”

He groaned for a moment, then took a few steps back and gave the order to the seven battle droids that had been waiting beside him.

"With a shoulder cannon, at this stone, three salvos!"

"Whoa......

After receiving his order, the seven battle robots looked up at the boulder in unison, and at the same time, the shoulder cannon on the shoulder quickly adjusted its angle, and the muzzle of the cannon began to glow blue.

"Boom ......"

"Boom ......"

Soon, seven explosions rang out one after the other.

It lasted for three rounds before it stopped.

Sun Cheng waited for the salvo of the battle robots to finish, and then walked back to the boulder, and re-tested the situation where the three salvos of the seven battle robots bombarded the situation full of holes and cracks.

"No, the interference is still ............"

The core scanned the boulder again, only to find that there was still interference disrupting the electromagnetic waves he was emitting to penetrate the boulder.

Sun Cheng frowned slightly, and was thinking about where the problem was, when suddenly his gaze inadvertently swept over the ground, and his heart suddenly moved.

"Hey, those crumbling sands don't seem to be granite......"

Hurriedly bent down and picked up a broken boulder fragment from the ground, and Sun Cheng took it in his hand and examined it carefully.

When his gaze had just inadvertently swept over the fragments of the boulder on the ground, the core unexpectedly gave a detailed analysis of the ingredients, which made Sun Cheng feel refreshed.

He is no stranger to this ingredient analysis, as he has been constantly sifting through the technology arsenal of Cybertron for transactions with China and Russia for some time now.

Therefore, Sun Cheng wrote down a technical information on a kind of high-strength concrete that was once prevalent on the planet Cybertron.

Unfortunately, if the core analysis is correct, the composition of these fragments falling from the boulder is almost identical to that of the high-strength concrete.

In other words, the boulder in front of him was not granite at all, but a high-strength concrete block made with Cybertron technology.

"It's getting more and more interesting......"

In his eyes, the light of excitement shone brighter and brighter, and Sun Cheng could now determine that there must be some secret hidden in this boulder.

He looked at the boulder again, and after a little calculation in his mind, he didn't let the battle robots continue to consume energy.

Instead, he went into battle himself, and after retreating a certain distance, Sun Cheng quickly summoned his P4-level plasma cannon and bombarded the boulder.

"Boom ......"

The violent explosion kicked up countless clouds of sand, and when the dust settled, he quickly withdrew his weapon and walked back to the boulder to look at it again, and couldn't help but smile even more on his face.

Under the bombardment of his plasma cannon, the boulder was completely gone, and splinters were scattered everywhere.

However, it is the monolith that was created using Cybertron's high-strength concrete technology.

The boulder had not been completely destroyed, and a ruined stone pier could still be seen in its place, and on top of the stone pier, a square chest about the size of a human suitcase was unexpectedly revealed.

The cold light of Sensen flashed on the top of the square cabinet, and at a glance it was made of metal, and even if it ate his plasma cannon blow, there was no crack on it.

The bottom of the metal cabinet is still wrapped in stones!

Sun Cheng was in a hurry to take down the cabinet and take a look at the contents inside.

At that moment, he stepped forward and violently clamped the stone body below, and it fell with a few punches.

With a flurry of fists, the square cabinet that had been tightly fastened to the stone pier also began to loosen.

Finally, with his final punch falling.

After shaking violently, the square cabinet also flew up from the stone pier and landed in a pile of rubble not far away.
