After all, it''s a sewer, a place to hide dirt.

    Although Decepticons have no human respiratory system, they can''t feel the pungent smell that may exist.

    But Sun Cheng doesn''t think the sewer where rats and cockroaches jump everywhere will be a good place, especially when a cockroach accidentally flies and falls on his face.

    But now it''s important to run for his life. Now he immediately switched back to beast form and ran quickly towards the city center.

    The reason why he fled to the city center rather than the suburbs is that although he is closer to the suburbs, sun Cheng has no doubt that he has attracted the warning force of the whole Tucson city to the suburbs.

    With the logic of normal people''s thinking, they will certainly think that after he sneaks into the sewer, he will continue to flee to the suburbs.

    So at this time, he suddenly fled in the opposite direction, and the possibility of escape was greater.

    As for the detection device in the hands of the Yankees, he was not very worried. Although the sewer in Tucson was well repaired, it was not luxurious enough for humans to chase him on motorcycles.

    Therefore, even if they had detection devices and finally found his escape direction, it was difficult to catch up with him.

    Sure enough, more than 40 minutes later, when sun Cheng jumped out of the suburban sewer in the other direction, he never met anyone who surrounded him again.

    The thrilling trip to Tucson almost frightened him.

    Fortunately, sun Cheng was smart enough. After successfully escaping, he went all the way north, raised the speed to the limit, and arrived in Flagstaff, a northern city in Arizona, a few hours later.

    The [baglin crater] he is tracking down now is located in Flagstaff. Although after many years, even he doesn''t think he can leave any clues here, sun Cheng made a trip in the spirit of taking the chance of killing mistakes.

    Baglin crater is located on the desert plateau southeast of Flagstaff. Like most parts of Arizona, it has a dry, desolate and remote climate.

    With his previous experience in Tucson, sun Cheng''s character was undoubtedly more cautious. Before reaching the baglin meteorite crater, he first released two groups of insect scouts to investigate the nearby area. After it was determined that there was no ambush or other humans, it quickly approached the meteorite crater.

    I have to admit that sun Cheng was surprised when he watched the baglin crater close at hand.

    "With a diameter of 1.2km and a depth of 150m... Based on the impact strength, this must be at least a huge meteorite with a diameter of 30 or 40 meters..."

    However, he was shocked by the power of meteorites. After close observation, he quickly calculated some data. Sun Cheng couldn''t help but move in his heart.

    A huge meteorite that fell from the sky 10000 years ago, even if it was crushed and weathered when it fell, it may not be much smaller. With the capacity of American construction machinery more than 90 years ago, it is absolutely difficult to transport it to further places, unless it is transported by water.

    As far as he knows, there are two black gorge towns in Wyoming and Colorado, one on the plateau and the other at the foot of the mountain. The two towns have one thing in common, that is, they are very far away from here.

    In contrast, the black gorge at the junction of Nevada and Arizona is much closer to here.

    In addition, from Flagstaff to black gorge, there are almost unobstructed river channels for water supply and transportation.

    If sun Cheng had to choose, he would have chosen to transport the meteorites there more than 90 years ago.

    The premise is that the meteorite must be a "fire source", otherwise he can''t think why the Yankees spend so much money to transport a large stone from a place that is not easy to be exposed to another place that is more difficult to be exposed, even if it is a meteorite.

    After walking around the crater for a while, sun Cheng even went down to the crater and looked carefully for a while. As expected, he couldn''t find any useful clues. He didn''t feel disappointed. After all, it has been more than 90 years since the meteorite was transported away, and time has already erased all possible clues.

    Flagstaff is not far from attacking the base in the Grand Canyon. The short distance of more than three or four hundred kilometers is only two or three hours for sun Cheng, who has lifted the danger alarm and slowed down.

    A few hours later, he had reached the Grand Canyon and returned to the base of the attack.

    "Attack your excellency, I''ll disturb you!"

    On the platform outside the base, sun Cheng first issued a section of communication right to the attack in the cave. It should be polite. Sun Cheng also knew that there were surveillance equipment placed on the platform. Although the location was very hidden, he could not hide from him who was equipped with the [spy template].

    After reminding the other party, he was about to go in, and suddenly received the other party''s communication, "have you found the clue about the [ignition source]?"

    "No, I''m still tracking down! I came here this time because I found some deficiencies in the body these days. I want you to help me deal with it."

    Sun Cheng didn''t mention the meteorite in baglin crater because he hasn''t determined whether the meteorite in baglin crater is a source of ignition.

    He didn''t want to. After he sent the communication, he soon received a reply from the other party.

    "Don''t bother me if you don''t find it? Get out..."

    A cold reply from the attack stopped sun Cheng, who had just stepped into the cave for a few steps. He was stunned there. For a moment, it was like falling into an ice cave, cold from inside to outside.

    Although I had guessed before that the attack would help me transform my body, the purpose was just to use his intelligence search expertise to do things for myself, just like Starscream.

    However, compared with roadblocks, starscreams, sound waves, spectroscopes, laser birds and others, the Decepticons sun Cheng has been in contact with for the longest time since he crossed the world are attacks.

    Previously, he spoke very well most of the time, so that sun Cheng selectively ignored each other. Like roadblocks, starscreams and sound waves, they are Decepticons. In addition to improving their strength, there are only mechanical life of conspiracy, calculation and destruction left in their head. They have very different values and life attitudes from humans.

    The faint feeling of closeness to the attack in my heart also disappeared in this indifferent reply.

    "Am I thinking too much? I really can only rely on myself in this world!"

    Sun Cheng stayed quietly at the entrance of the cave for a long time before he reluctantly adjusted his mood. Then he folded and walked back without saying a word. He jumped off the platform and galloped to the "black gorge" at the junction of Nevada and Arizona.

    ps：

    1. Although the author Jun has always believed that even the protagonist can''t be the king at first, his mentality can be stronger only when he is gradually mature. However, for some readers, dada has been reacting that the strength of the protagonist is too weak. Seeing that there is no straightforward war of transformers, the author Jun decided to speed up the buff to the protagonist.

    2. Thank the readers for their appreciation.
