It took more than a week to shuttle back and forth between the United States and Brazil. After sending enough materials to base 2 for a period of time, sun Cheng temporarily stopped his busy work and returned to base 1.

    "... trouble, there are only a few power stations with a total installed capacity of more than 4 million kilowatts in Brazil..."

    The No. 2 base was built in Brazil. Sun Cheng regarded this South American power as his sphere of influence. Naturally, he also considered the acquisition or reconstruction of a power station in this country.

    The energy device can convert electric energy into high-purity energy liquid. Although the whole machine can only add up to more than two tons, its working efficiency is really not low. The power station with a total installed capacity of less than 4 million KW can not meet it at all.

    However, as one of the few countries in the world, Brazil has few power stations for sun Cheng to choose from.

    Located in the South American continent, Brazil, as the largest country in South America, is really a blessed fertile land.

    The vast national territory not only has rich and huge reserves of various mineral resources, but also a crossing Amazon River is undoubtedly the best gift from God to this country.

    As one of the new industrial countries, Brazil consumes a lot of electricity every year. However, by vigorously developing hydropower, Brazil can basically meet the domestic power demand.

    However, this is also the most troublesome place.

    Taking back his finger from the socket of the server, sun Cheng frowned slightly and thought.

    There are more than 2000 hydro thermal power stations in Brazil, but most of them are small hydro thermal power stations that can barely meet the power consumption in the region. There are only six power stations that meet his requirements, and all of them are hydropower stations.

    However, sun Cheng found it difficult to start with these six power stations.

    "The two main operators are the United States, one is Japan US joint venture, one is Japan US Pakistan joint venture, one is China Pakistan joint venture, and the other is operated by Brazilian state-owned enterprises..."

    One of the six hydropower stations has not been built yet, but each is difficult to intervene.

    Power stations of this scale are national projects in any country. Thanks to several successive presidents of Brazil in the past, none of them made concessions to capital for political achievements, resulting in a large number of foreign heavyweight giants participating in Brazil''s power market.

    Unfortunately, this is related to the competition between national economies, which makes sun Cheng a little difficult. He finds it difficult to get involved.

    "... it seems that we can only choose a slightly smaller power station again..."

    After thinking in his heart for a while, he shook his head and made a decision temporarily.

    After returning from Brazil, sun Cheng became a otaku in the base.

    Not that he wanted to, but recently several ground surveillance radar vehicles and air defense radar vehicles belonging to the U.S. military entered Colorado.

    It seems that the US government has become more and more impatient with these Decepticons who may be hidden in the territory. Under the circumstances of sky satellite reconnaissance and the alert of various military bases, the US government even does not hesitate to deploy a large number of ground surveillance radar vehicles and air defense radar vehicles equipped by the military to carry out coverage scanning throughout the country.

    Although they only wandered around sawoch County for one day, considering the scanning radius of these radar vehicles, sun Cheng had to stay in the base temporarily and was not ready to go out for a short time.

    This is not the only reason that forced him to stay and become a otaku. Another important reason is that he is ready to upgrade his power system!

    Deep in base 1, in lab 2.

    Sun Cheng returned to UAV form and lay quietly in the laboratory.

    Around him, six Decepticon engineers and a dozen spiders were busy around him.

    "Master, this power system is an improvement based on the power system on the spacecraft. Although it is not perfect, it is still a very excellent power system..."

    Beside him, Atlas is commanding several engineers to install a set of silver-white power system into sun Cheng''s body. At the same time, he doesn''t forget to explain the detailed data of the power system for him.

    "... this power system, we call it storm. After replacing it, master, your speed will be increased to Mach 2.7, and your load-bearing capacity will be increased by 1.8 tons..."

    "Well done..."

    Sun Cheng replied with satisfaction. It''s not hard to hear excitement in his tone.

    It''s hard for Decepticons to evolve. After all, the God of "fire source" is out of reach, and now the "fire source" has been destroyed.

    However, compared with the difficulty of evolution, the strengthening of the body is not so troublesome, but it is also quite difficult.

    In the past, although sun Cheng had the idea of strengthening his body, on the one hand, there was no strengthening technology, and on the other hand, the conditions were not allowed.

    Now he has succeeded in changing his guns. He has a ship of Hunter civilization for his research, and he has an extra team of Decepticons to use. Finally, he can improve his strength by constantly strengthening his body.

    Xu Shi saw that he was in a good mood. Atlas hesitated for a moment and then said, "master, we haven''t made much progress in jazz''s body research. Many of the technologies used by the Autobots are different from those of our Decepticons. We can''t find his core and completely peel off the fire."

    When he mentioned jazz, sun Cheng''s joy suddenly dissipated, and even his voice sank.

    "I see, continue to study..."

    Recently, the wind outside has been tight day by day, and his demand for a powerful new body is imminent.

    But atlas can''t urge him. Technically, although sun Cheng is still learning, some technical problems can''t be solved by urging him. He still knows.

    This time, there is not only one set of power system for the upgrading of their own body.

    Along with it is an engineer No. 1. They imitate the hunter''s plasma weapon. The power of the newly designed plasma gun has increased a lot, and the energy consumption has also increased. On the way, they also made some modifications and adjustments to sun Cheng''s original Vulcan gun.

    The whole transformation process lasted two days before it was completed!

    In the laboratory, accompanied by a reminder from atlas.

    Sun Chengyue, who had already been suffocated, jumped up. There was a crackling sound of metal joints in the body, and soon changed back to human form.

    "... it feels good..."

    When his heart moved, the joints of his right hand immediately wriggled and deformed. Soon, a short handle small gun with a caliber of 100 mm appeared in his hand. He took it in his hand and aimed at the front. It took a long time to suppress his desire to pull the trigger.

    Have the intention to test their own body performance after transformation. They have also been suffocated by being a Houseman in the underground base for this period of time.

    Sun Cheng carefully tested the running in of the body with the core. After determining that there was no hidden danger, he immediately ordered atlas. He soon went out from a newly opened hidden channel of the base, took a leap to the air, and soon disappeared.

    ps：

    A few days ago, I didn''t feel at all. I was so blocked that I couldn''t even type hundreds of words all day. I''m very sorry.
