Several people walked quickly to the noisy place, and soon came to an irregular circular pit!


    The round pit is slightly elliptical, with a radius of no less than seven or eight meters, and the distance from the top to the deepest part of the pit bottom is no less than ten meters.


    We can dig such a big pit in less than an hour. We can see how high the work efficiency of several excavation machines is.


    Sun Cheng was not in a hurry to get in. There were old words on the ruins of [tiawanako city]. As long as he was related to the Pathfinder and had his previous experience in Lop Nur, he felt that he could not be too careful.


    The worst situation here is that only a pathfinder visited and contacted the ancient Indians a long time ago, so the elder characters were branded on the ruins of [tyawanaco city].


    But if the other party has not only visited here, the results will be very different.


    Especially when he is almost the enemy of the whole world, he needs to gamble!


    He didn''t go down to the pit. Sun Cheng was a cautious man. He didn''t urge him when he saw that the sprint was still contacting the excavation robot that had just fallen into the pit.


    Soon, more detailed information was fed back.


    "Master, please look!"


    Sprint a little at his temple, and the next moment two beams of light will shoot out from his eyes. The environment around them suddenly seems to have changed, and they are in a slightly sea blue channel.


    This is virtual imaging technology, and sun Cheng is no stranger.


    The image projected by the sprint is obviously taken from the first perspective of the mining robot.


    Looking carefully, it is not difficult to find that this passage is not a natural underground corridor. It is a regular square with obvious man-made traces.


    Measured by the size of the excavation robot, the tunnel should be no more than two meters wide and about three meters high. Some patterns are engraved on the top of the wall and on the wall.


    However, it may be because South America has had many large earthquakes with a magnitude of more than 7 in modern times. Cracks of different sizes can be seen everywhere on the wall of the passage, which seriously damaged those patterns.


    So that sun Cheng tried to distinguish for a while and soon gave up.


    "Master, do you need to continue excavation?"


    In the pit, all the excavation robots have stopped working, and only the six transportation robots are still working hard to transport the earth and rock piled everywhere in the pit to the designated engineering earth and rock resettlement site one after another.


    Sun Cheng didn''t need to think at all, so he focused on it. His cold voice didn''t fluctuate: "dig, continue to dig all the way down to the target location!"


    He doesn''t care about destroying a civilization treasure handed down from the ancient Inca civilization, because compared with these, sun Cheng cares more about what kind of secret is buried in this building which is obviously deliberately hidden underground!


    "Yes!"


    Their masters don''t care. The Decepticons who sprint this standard are even less likely to have compassion for what humans have created!


    With his order, the digging robot that had fallen into the tunnel and the five platforms that stayed outside turned into hard-working diggers again, and the broken bricks and stones and soil piled up again in the pit.


    In the roar of excavation, the sky lit up bit by bit.


    Although Mora had arranged the guards in advance, he pulled out a cordon on the periphery, which was enough to prevent humans from approaching.


    But Sun Chengxin is no more than the spy satellites of various countries that spread all over the earth and peep at every place on the planet.


    Especially when he learned from the two Decepticons who had just been dealt with not long ago that the sound wave had awakened, the uneasiness in his heart that he had been peeped at was bothering him all the time.


    Therefore, he can only endure his inner irritability and wait for the end of the robot''s work.


    This waiting is nearly two hours.


    Until the sunrise had risen and Bolivia ushered in a new day, the body surface was also full of the impulse of water droplets, which shook the body and reported to him in a slightly happy voice.


    "Master, the excavation robot has dug the underground main hall shown in the detection. We can go in!"


    Finally dug it!


    Sun Cheng couldn''t help nodding. Suddenly, several drops of water condensed on his head fell down.


    He ignored it and jumped straight down the hole to the hole where the digging robot had just fallen.


    The hole has expanded two or three times than two hours ago, with a radius of at least two meters, which is enough for him to pass with the huge Decepticon like sprint.


    The sprint has been distracted and controlled the operation of the excavation robot. Obviously, he knows the following situation better than him. Therefore, after sun Cheng jumped down, he didn''t hurry, but stayed outside and waited.


    Sun Cheng was not surprised. As soon as he jumped into the pit, he felt uncomfortable.


    This is not a spacious passage, but about four meters high and three meters wide. With his body, he must bend down to walk reluctantly.


    Bending to the bottom, although it looks very dark, the eyes of mechanical life are different from humans. They can clearly distinguish the surrounding terrain even in the dark, so even if there is no lighting, it does not affect their action.


    Sand, stone and soil particles are falling on your head. It is obvious that the violent means of excavation robots not long ago have damaged the stability of the stratum here.


    Sun Cheng lifted his feet that had fallen into the soft soil just now, and his eyebrows wrinkled slightly.


    "The passage is not stable. Mora follows me in. Sprint. You don''t have to come in."


    "Yes!"


    The voice of the sprint was obviously disappointed, but did not disobey his order. He retreated and left the pit, returned to the outside of the pit and looked around warily.


    Sun Cheng moved forward a few steps, and mora soon jumped down. After a little discrimination in the tunnel, he first gave a light sigh, and then quickly came behind him.


    "Master, there''s something strange here!"


    "Huh?"


    Sun Cheng stopped, reluctantly turned around and looked at him, and then asked, "what did you find?"


    Mora''s body looks the same as human beings, so the passage that sun Cheng can only bend over is very wide for him.


    Mora was obviously excited when he heard the speech. He hurried to one side of the pit and pointed to a broken wall painting on the wall. He was a little excited: "there are words on the broken wall painting in the pit!"


    "Text?"


    Sun Cheng was a little stunned, and soon his heart moved. He had already reacted, "words!"


    "Yes, words!" Mora nodded affirmatively, "Although the Inca civilization is regarded as the most brilliant civilization left by ancient humans in South America, it is well known that the Inca civilization has not been able to form and create a set of unique words and pass them down since its birth and death. When Lord magic and Lord atlas cultivated me, they left a lot of information about ancient Indians in my core, if I didn''t If you read it wrong, the characters on these wall paintings are indeed words, and these words are just stored in my core. They are called [Mayan words]! "
