After spending more than a week shuttling back and forth between the United States and Brazil, and delivering enough supplies to base No. 2 for a period of time, Sun Cheng temporarily stopped being busy and returned to base No. 1.

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

The second base was built in Brazil, and Sun Cheng regarded the South American power as his sphere of influence, so he naturally considered the question of buying or rebuilding a power station in the country.

The energy device can convert electrical energy into high-purity energy liquid, not to mention that the whole set of machines together is only more than two tons, but its working efficiency is really not low, and a power station with a total installed capacity of less than 4 million kilowatts cannot meet it at all.

However, Brazil, as one of the few countries in the world, does not have many power stations in the country for Sun Cheng to choose from.

Located on the South American continent, Brazil, as the largest country in South America, is truly a godsend.

In addition to the vast territory of the country, there are not only rich and huge reserves of various mineral resources, but also a passing 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, but it can basically meet the domestic electricity demand by vigorously developing hydropower.

However, this is also where the most troublesome part.

Retracting his finger from the insert of the server, Sun Cheng frowned slightly and thought about it.

There are more than 2,000 hydrothermal power stations in Brazil, but the vast majority of them are small hydrothermal power plants that can barely meet the needs of the region, and only six power stations meet his requirements, and all of them are hydroelectric power stations.

However, Sun Cheng found it difficult to get his hands on these six power stations.

"The two main operators are the United States, one is a joint venture between Japan and the United States, one is a joint venture between Japan and the United States and Brazil, one is a joint venture between China and Brazil, and the other is a ...... operated by a Brazilian state-owned enterprise."

One of the six hydropower plants has yet to be built, but each one is difficult to get by.

A power plant of this size is a national project in any country, and thanks to the successive presidents of Brazil, all of whom have made concessions to capital for the sake of political performance, a large number of foreign heavyweights have intervened in the Brazilian electricity market.

It's a pity that this kind of competition between national economies behind the scenes makes Sun Cheng a little difficult, and he finds it difficult for him to get involved.

“…… It looks like we'll have to choose a smaller power station again......"

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

After returning from Brazil, Sun Cheng became an otaku in the base.

It's not that he wants to, but recently several ground surveillance radar vehicles and air defense radar vehicles belonging to the US military have entered the territory of Colorado.

It seems that the US Government has become more and more impatient with these Decepticons who may be hiding in its territory, and it has not hesitated to deploy a large number of ground surveillance radar vehicles and air defense radar vehicles equipped by the military to various parts of the country for coverage scanning under the condition of satellite reconnaissance in the sky and the alert of various military bases.

Although they had only been around the territory of Savoch County for a day, considering the scanning radius of these radar vehicles, Sun Cheng had to stay in the base for the time being, and he was not ready to go out for a short time.

The reason why he was forced to stay as an otaku was not only this, but another important reason was that he was ready to upgrade his power system!

Deep in Base 1, inside Laboratory 2.

Sun Cheng changed back into the form of a drone and lay quietly in the laboratory.

Around him, six Decepticon sappers and a dozen spiders surrounded him, busy non-stop.

"Master, this power system is an improvement we have made based on the power system on the ship. It's not perfect, but it's still a very good powertrain......"

Beside him, Atlas was commanding several sappers to install a set of silver-white power system into Sun Cheng's body, and at the same time did not forget to explain the detailed data of this power system to him.

“…… This powertrain, we call it a storm. With it, you will be able to increase your speed to Mach 2.7 and your weight capacity will increase by 1.8 tonnes......"

"Well done......"

Sun Cheng replied with satisfaction, and it was not difficult to hear excitement in his tone.

It is very difficult for the Decepticons to evolve, after all, the [Tinder Source] is an unattainable artifact, not to mention that the [Tinder Source] has been destroyed now.

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

In the past, even though Sun Cheng had the idea of strengthening his body, first, there was no technology to strengthen it, and secondly, the conditions did not allow it.

Now that he has successfully exchanged shotguns, he has a ship of the Hunter civilization for him to study, and he has an extra team of Decepticons to use, so he can finally improve his strength by constantly strengthening his body.

Xu saw that he was in a good mood now, and Atlas hesitated for a moment before continuing: "Master, in terms of Jazz's body research, we haven't made much progress for the time being. Many of the technologies used by the Autobots are different from those of our Decepticons, and we have never been able to find his core and completely separate the fire. ”

Hearing him mention Jazz, the joy in Sun Cheng's heart suddenly dissipated a lot, and even his voice sank.

"Got it, let's continue research......"

The limelight has been tightening lately, and his need for a powerful new body is imminent.

But Atlas can't urge it, although Sun Cheng is still learning technically, some technical problems are by no means the reason that can be urged, he still understands.

This time, the upgrade of his body is not just a power system.

Along with it, there is also a sapper No. 1 plasma weapon that they imitate the hunter, the newly designed plasma cannon has increased a lot in power, and the same energy consumption has also risen, and by the way, Sun Cheng's original set of Vulcan cannon has been modified and adjusted.

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

In the laboratory, accompanied by a reminder from Atlas.

Sun Cheng, who had already been suffocated, jumped up, and the crackling sound of metal joints kept coming from the body on his body, and he quickly changed back into his human form.

“…… Feel good......"

As soon as his heart moved, the bone joint in his right hand immediately squirmed and deformed, and soon there was an extra short-handled cannon with a caliber of 100mm in his hand, and he took it in his hand and aimed it forward, and it took a long time to suppress the desire to pull the trigger.

I had the intention to test the performance of my modified body, but I was also suffocated by being an otaku in the underground base for this time.

Sun Cheng carefully tested the body run-in with his core, and after confirming that there was no hidden danger, he immediately gave Atlas an order, and he quickly walked out of a newly opened hidden passage in the base, and flew into the air with his body, and soon disappeared.

ps：

A few days ago, I didn't feel it at all, and my thoughts were so blocked that I couldn't even type out hundreds of words in a day, so I'm very sorry. [.]
