Africa, Ethiopia.


    Under their guidance, Optimus Prime walked in a dry valley.


    "Leader, this is one of the four best places we have selected for the new iron castle city, and it is also the most suitable place we think!"


    "This is located in the East African Rift Valley. The underground volcanoes can provide us with sufficient geothermal resources. I asked Jack. He can manufacture the most advanced geothermal power generation equipment for us..."


    "The rift valley area is not suitable for human habitation, so there are only a few small tribes with a population of no more than 1000 within 200 kilometers around, except for occasional human tourists. They were accidentally discovered by one of the human tribes, but unexpectedly they were worshipped as gods of tribal faith..."


    "Ethiopia is very close to the sori country where our temporary base is located, with a straight-line distance of no more than 500 kilometers... According to the information we have obtained from the human Internet, although Ethiopia is the least developed country on the earth, it is also one of the countries with the most abundant resources in Africa..."


    "They spent a few days and conducted a lot of exploration nearby... They think we can build a new iron fort in this dry valley. The new valley after diversion is very close to here. We can build a hydropower station there to provide energy for us..."


    Optimus Prime listened carefully to the explanation of the iron sheet, and his eyes followed his instructions from time to time, browsing through the dry river valley.


    The new tiebao City, located on the earth, will certainly not reach the scale of the former Autobot capital in the future.


    This is inevitable, because tiebao city was the capital of Cybertron during the Senate, with a history of millions of years.


    Moreover, Cybertron is a huge metal planet with a volume similar to that of Saturn, which is close to the earth. The volume of the planet alone is more than 800 times that of the earth.


    The former tiebao City, with a total area of an amazing 500000 square kilometers, is the largest city on Cybertron, even much larger than the total area of most countries on earth.


    Of course, Optimus Prime never thought that the new iron castle city could be compared with the former capital iron castle.


    With the current strength of the Autobots, it is possible to reproduce the scale and grandeur of the iron fort in the past unless the details are exhausted and all work together.


    Unfortunately, the Autobot is no longer the original Autobot.


    The failure of the civil war intensified the division within the Autobots. The old aristocrats gradually mastered the vast majority of power in the Autobots camp through the Autobots Parliament. Even his young leader was forced to leave. It can be seen how rampant their power is now.


    The previous compromise did not mean that Optimus Prime recognized the old aristocrats and was willing to become a puppet leader controlled by them.


    Therefore, the contradiction between the two sides is irreconcilable. It is estimated that it is difficult for the Autobots to twist into a line.


    The iron sheet with a bad temper can hardly bear it. He introduced Optimus Prime in detail for a long time.


    Seeing that he just looked but didn''t speak, he scratched his head and looked at ALCI next to Optimus Prime.


    ALCI nodded and asked in harmony, "are you still worried about bumblebees?"


    Optimus Prime was silent for a moment, then nodded and said, "Well!"


    At this time, more than a week has passed since the end of World War I on trindadi island.


    Although I got information from sun Cheng that my teacher''s spacecraft against natural enemies fell on the moon.


    But the Autobots did not fully believe him. After returning, Optimus Prime sent his most powerful agent, Bumblebee, to the moon.


    The reason why he seems a little worried now is that the information given by sun Cheng shows that the Decepticons have established a base on the moon.


    The base is a vital existence for both Autobots and Decepticons.


    It can be both the barracks of Decepticons and their smelting and mining centers.


    Considering that Starscream, another elder of the Decepticon army, is likely to sit in the Decepticon base on the moon.


    Optimus Prime naturally realized the danger of this pathfinding. If he could, he would prefer to send an experienced police car.


    Unfortunately, when he sent the police car to Jordan to explore the way first a month ago, there was no news.


    So far, the Autobots have not found his body, and it is unclear whether the police car has been poisoned by Decepticons or captured.


    "If there is no problem with the confused information, I''m afraid the current moon has been firmly grasped by the Decepticons... The Bumblebee''s past exploration is still very dangerous!"


    After telling his worries, Optimus Prime looked at tin and apologized, "tin, you''ve worked hard for a while. I''m very satisfied with the location of this place!"


    Tin nodded, "leader, let''s go to the other three places first. Only when you make a decision can we start building a new iron castle city!"


    "There is no need to go to the other three places. After you gave me the geographical coordinates, I have found the nearby satellite map through the human Internet. Indeed, as you said, this is the most suitable place."


    Optimus Prime was a little distracted just now, but he listened to the introduction of tin.


    As mentioned by tin, this dry valley in the rift zone is really good.


    This dry valley is about 11 kilometers wide and more than 1000 meters deep. Both sides are hard mountain walls. Autobots can build the main buildings of xintiebao city at the bottom of the valley. They can also build some research institutes and other institutions that need to be kept secret and vigilant against Decepticon invasion into the nearby hard mountain walls.


    This is how many Decepticons and Autobots are built on Cybertron.


    The only difference is that Cybertron is a metal planet, and the hardness of the mountains is much higher than that of the earth.


    When tin and others heard the speech, they were all overjoyed.


    "I see, leader!" he excitedly saluted, "I''ll pass on your order and ask the temporary base to send someone to build our new iron castle city as soon as possible!"


    Although the earth is far less than Cybertron at its peak, it is undoubtedly more vibrant than the dying planet.


    Most Autobots, including tin, are very happy that Optimus Prime is willing to build a new home for them on earth.
