Chapter 271： Thermal power generating set

The defense of the city is not what it used to be, and the inner and outer cities are densely packed. Coupled with the full play of thousands of elf shooters, Jia Zhengjin also uses his newly learned skills to desperately swallow potions and use explosive arrows to brush wildly.

Behind the kobold crossbowmen joined the young new crossbowmen team led by Amber.

The fierce battle continued until about 0 o'clock in the middle of the night, and finally left behind a pile of horrible giant worm bodies in both the inner and outer cities, and won the final victory!

Although a few giant insects appear occasionally, the number is not enough to break through the defense of the arrow tower and threaten the residents of the city!

Everyone involved in this battle is almost exhausted and weak. However, because it was a long-range operation, there was no casualties except for a relatively unlucky town guard who was injured in the foot by the body of a giant insect that fell from the sky. This is also a great fortune in misfortune!

Jia Zhengjin's hand is too tired to lift, he can't remember how many arrows were shot!

Only know that the battle tonight, let him directly from 12 to 13!

If you want to upgrade from level 12 to level 13, you need more than 200,000 experience points. Even if I went to Tan Sandia City before, and after I came back, I hunted some Warcraft. But how much experience is there? In fact, almost all of the 200,000-level experience contributed by this terror wave of bugs!

The only regret is that no boss appears. In addition to being able to break down into insect shells, insect wings, and a large amount of raw meat, the corpses of insects can't find any loot.

The newly acquired skill points are considered to be added to the power system again and again.

After learning the power system knowledge, you can unlock the most basic production of thermal power generating units. Upgrading this skill can unlock other types of generator sets such as hydropower, wind power, solar power and even nuclear power.

Although Jia Zhengjin already has a magic core battery, after all, the magic core is obtained by hunting and killing Warcraft. How hard it is to find a Warcraft in the electrical department, Jia Zhengjin has a deep experience.

Furthermore, the magic core battery has capacity. The power that can be maintained is also quite limited, and it will be gone after it is consumed! This is a one-time thing, not so cost-effective! It is okay to use it in an emergency, such as generator maintenance, and use it when there is no electricity. Or some equipment that needs electricity and can not be carried by the generator set can also be driven by magic core batteries. For example, it is possible to build armor for giant aircraft battles later.

However, it is quite troublesome to make a thermal power generating unit, because the whole unit needs five important components: power system, control system, muffler system, shock absorption system and exhaust system.

And these five systems are composed of many different parts. These parts have a smaller combination of parts!

Even if there is a system, it is quite a troublesome manufacturing process.

Fortunately, Jia Zhengjin is not short of materials and time. As long as you work hard in the factory, you can make it soon.

However, there is a problem that the operation of the power system drives the city's lighting system. And the lighting system can easily attract terrifying bugs!

Tonight is just 50 streetlights, which directly attracts a worm wave that is enough to make Jia Zhengjin soar to the first level!

A bug has about 10 to 20 experience points. In other words, about 20,000 to 30,000 giant insects were killed tonight!

The upgrade is right soon! Fortunately, this wave is full of attacking and defensive bugs. If it is a more powerful insect wave, I am afraid that the city will suffer.

But finally got the magic core battery and generator set, but can't it be used for night lighting?

Jia Zhengjin thought left and right, and suddenly he was alive.

Insects are so troublesome and dangerous when they enter the city, wouldn't they just let them in?

As for the method, Jia Zhengjin thought of one.

Isn't there an arrow tower in the inner and outer cities anyway? And it will definitely continue to be built in the future, until the arrow towers are erected in every corner of the inner and outer cities.

The most troublesome thing now is when the tide comes, because the number is so horrible, the arrow tower can't completely block all their travel routes. A lot of insects will be put into the city, and the shooter needs to participate in the battle to clear it.

How about building a protective net on the periphery and the sky? Not only can intercept insects, but also allows the arrow tower to attack insects through the gap! And you can power on the protection netcom and turn it into a power grid to make the bugs die faster!

Under normal circumstances, this concept is very difficult to achieve, and it will inevitably require very scary human resources and sophisticated planning.

However, Jia Zhengjin, who owns the gaming system, said it seems not too difficult?

Iron ore can be used to smelt wire mesh in the furnace, as well as a strong iron fence. He can completely surround the outer city walls with barbed wire, and then build it over the city to form a super large roof with barbed wire. Next, a sturdy iron fence is used to enclose the entire city.

After the power is turned on, except for the four gates can be freely entered and exited, regardless of the blockade of the upper and lower laws!

Power grids and electric fences can isolate any flying troops outside and prevent them from entering the city! However, there is also a disadvantage that the flying units in their own city cannot enter and leave at will. If you want to bring Warcraft, fake dragons or something into the city, you can only pass through the four huge gates.

Of course, if the city can be made safe, this is totally worth doing!

It is really necessary to pull up the protective net. The grid and the defense of the arrow tower are enough to isolate any aerial attacks. It can also cause some trouble to enemies siege. Although it is part of the trap, UU reading has no experience bonus for killing insects, but safety is more important than experience! By then, you have to do it yourself, but just do some repairs to the broken iron fence and barbed wire! How simple? Take a look at the hammer and it will be ok!

When I thought about it, Jia Zhengjin took advantage of everyone going back to sleep and worked overtime at the factory. He first manufactured all the complex parts for the generator set, and then took it to the tool table to start assembly.

As for the inside of the furnace, smelting began to produce barbed wire.

When he succeeded in assembling a complete thermal power generating unit, there was already quite a lot of barbed wire in the furnace. He immediately took them out and hurried out to install them.

The iron fence cannot be done for the time being, because too much iron ore is required and resources cannot keep up. Need to wait for news from the mine!

He first built four towering pillars in four directions in the inner city. The pillars are made of wood, but they are strong. Then use the pillars as support, install barbed wire horizontally in all directions, and create a barbed wire roof above the city.

Of course, the whole course borrowed Buddy's flying Warcraft Kuru, otherwise who can build in such a high place?
