I can''t help feeling a little disappointed!


    Sun Cheng turned back and looked at the boulder carefully. He was about to take back the battle robot and prepare to leave.


    At the moment of turning around, a flash of light suddenly flashed in his mind: "granite boulder... Wait... Damn it, such a simple means of concealment, even I was almost cheated..."


    Although Lop Nur has not been a desert since ancient times, it may have been a fertile river and grassland a long time ago.


    However, one thing sun Cheng can confirm is that the geological structure near here can never naturally breed such a large piece of granite.


    yes!


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


    It was either transported here from a distance by the explorers of Decepticons or Autobots a long time ago, or by humans who worship them as gods.


    But no matter who brought it, there is no doubt that this granite will be transported here all the way. There must be a reason behind it!


    At that moment, he gave up the idea of leaving, came back to the boulder, stared at it and checked it carefully.


    It didn''t matter. Sun Cheng soon noticed the strangeness.


    "Sure enough, it''s strange!"


    His eyes could not help showing a touch of excited light. He stared at the boulder in front of him, and finally had a smile on his mouth.


    From a human point of view, it is difficult to detect anything wrong with this huge stone.


    However, after sun Cheng realized that there was a problem with the boulder, the scanning electromagnetic wave emitted by his body never stopped. He has been scanning the boulder continuously to try to find the problem.


    He had thought that explorers from Cybertron had hidden the entrance of a cave or some base with boulders.


    It never occurred to me that even if the electromagnetic wave penetrated into the extreme depths of tens of meters underground, no caves or other things were found.


    Instead, it is inside the boulder, like something interfering with his electromagnetic wave scanning.


    The electromagnetic wave from his core can never penetrate this boulder!


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


    Come to the boulder, reach out and gently brush it on the apparently polished smooth surface of the boulder.


    Sun Cheng hesitated for a moment, but he still couldn''t restrain his inner curiosity.


    So he punched the boulder and blew it over.


    "Bang!"


    The metal fist made of alloy fell heavily on the boulder, making a dull collision sound. Several pieces of broken small stones immediately fell from the place where his fist hit the boulder.


    Sun Cheng quickly took back his fist, frowned and looked at it. There was only a shallow fist print on it, and more than a dozen tiny cracked boulders. He couldn''t help muttering, "it''s quite hard!"


    He pondered for a moment, then retreated a few steps and gave orders to the seven combat robots waiting nearby.


    "With a shoulder gun, shoot at this stone in three rounds!"


    "Wow..."


    After receiving his order, the seven battle robots all looked up at the boulder. At the same time, the shoulder gun on the shoulder quickly adjusted the angle, and the muzzle began to shine a faint blue light.


    "Boom..."


    "Boom..."


    Soon, seven successive explosions came from the boulder.


    It lasted three rounds before it stopped.


    Sun Cheng waited until the volley of the battle robots was over, and then went back to the boulder. He retested the situation where there were pits and cracks everywhere in the three rounds of Volley bombardment of seven battle robots.


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


    The core scans the boulder again, and it is found that there is still interference disturbing the electromagnetic wave sent by him to penetrate and scan the boulder.


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


    "Eh, the broken sand doesn''t seem to be granite..."


    He quickly bent down and picked up a broken boulder fragment from the ground. Sun Cheng took it in his hand and looked at it carefully.


    The core accidentally gave a detailed composition analysis when he just inadvertently swept the boulders and fragments on the ground, which gave sun Cheng a boost.


    He is no stranger to this component analysis, because some time ago, he has been constantly screening technologies that can be traded from the science and Technology Library of Cybertron for transactions with China and Russia.


    Therefore, sun Cheng wrote down a technical data of a kind of high-strength concrete that was once popular on Cybertron.


    Unfortunately, if the core analysis just now is correct, the composition of these fragments falling from the boulder is almost the same as that of the high-strength concrete.


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


    "More and more interesting..."


    In his eyes, the light called excitement flashed brighter and brighter. Sun Cheng can now be sure that there must be some secrets hidden in this boulder.


    He then looked at the boulder again. After a little calculation in his heart, he didn''t let the battle machines continue to consume energy.


    Instead, he went to battle himself. After retreating for a distance, sun Cheng quickly summoned his P4 plasma gun and blasted it at the boulder.


    "Boom..."


    The violent explosion set off countless dust. After the dust settled, he quickly took back his weapons and walked back to the boulder. When he looked again, he couldn''t help smiling more.


    Under the bombardment of his plasma gun, the boulder had completely disappeared, and the fragments splashed everywhere.


    However, it is the boulder made by using Cybertron''s high-strength concrete technology.


    The Boulder has not been completely destroyed, and a damaged stone pier can still be seen in the original place. On the stone pier, a square cabinet about the size of a human suitcase is accidentally exposed.


    There was a cold light shining on the square cabinet. It was made of metal. Even if it was hit by his plasma gun, there was no crack on it.


    The lower part of the metal cabinet is still wrapped by stones!


    Sun Cheng was eager to take down the ark and take a look at the things inside.


    At that moment, he came forward and roughly clamped its stone body under it, which fell down with a few fists.


    With a burst of slapping fists, the square cabinet that was tightly fixed on the stone pier began to loosen.


    Finally, with his last punch.


    After shaking violently, the ark also flew up from the stone pier and landed in a pile of broken stones not far away.
