The city's defenses are no longer what they used to be. There are dense defenses inside and outside the city. In addition, thousands of elf archers are exerting their full strength. Jia Zhengjin also uses his newly learned skills to swallow potions and use explosive arrows to shoot wildly.
Behind them were kobold crossbowmen and a new team of young crossbowmen led by Amber to join the battle.
The fierce battle continued until around 0:00 in the night, and finally won the final victory after leaving mountains of terrifying giant insect corpses in both the inner and outer cities!
Although a few giant insects still appear occasionally, the number is no longer enough to break through the defense of the arrow tower and threaten the residents in the city!
Almost everyone involved in this battle was almost exhausted from exhaustion. However, because it was a long-range battle, except for a relatively unlucky town guard who was injured in the foot by a giant insect corpse that fell from the sky, there were no casualties. This can be regarded as a great blessing among misfortunes.
Got it!
Jia Zhengjin's hands were too tired to lift up. He couldn't remember how many arrows he shot in total!
All I know is that tonight's battle made him directly upgrade from level 12 to level 13!
You must know that it takes more than 200,000 experience points to upgrade from level 12 to level 13. Even if you went to Tanzania City before and hunted some Warcraft after you came back, how much experience is that? In fact, these 20
Almost all the experience worth tens of thousands was contributed by this terrifying wave of insects!
The only regret is that no BOSS appears. And apart from the fact that the insect corpses can be decomposed into insect shells, insect wings, and a large amount of raw meat, no loot can be found.
The newly acquired skill points were added to the power system after careful consideration.
After learning the knowledge of power systems, you can unlock the most basic production of thermal power generation units. Upgrading this skill can unlock other types of power generation units 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 Warcraft. Jia Zhengjin fully understands how difficult it is to find an electric Warcraft.
Furthermore, the magic core battery has a capacity. The power it can maintain is also quite limited, and it is gone after it is consumed! This is a one-time thing, not so cost-effective! It is okay to use it in emergencies, such as generator maintenance.
, use it as a substitute when there is no power. Or if some equipment that requires power cannot carry a generator set, it can also be driven by a magic core battery. For example, the giant mecha armor that may be built in the future.
However, it is quite troublesome to make a thermal power generation unit, because the entire unit requires five important components: power system, control system, silencer system, shock absorption system, and exhaust system.
And these five systems are composed of many different parts. These parts are also composed of smaller parts!
Even if there is a system, it is still a very troublesome production process.
Fortunately, Jia Zhengjin does not lack materials or manufacturing time. As long as he works hard in the factory, he can make it quickly.
But there is a problem. The operation of the power system drives the city's lighting system. And the lighting system can easily attract terrifying insect waves!
There are only 50 street lights tonight, which directly attracts a swarm of insects that is enough to make Jia Zhengjin rise to the next level!
One insect has about 10 to 20 experience points. In other words, we killed about 20,000 to 30,000 giant insects tonight!
It's true that the upgrade is very fast! But fortunately, this wave is full of insects with low attack power and low defense power. If it were a stronger insect wave, I'm afraid the city would suffer.
But after finally getting the magic core battery and generator set, can't they be used for lighting at night?
Jia Zhengjin thought about it, and suddenly an idea came to him.
Insects are so troublesome and would be dangerous if they entered the city, so why not keep them at bay?
As for the method, Jia Zhengjin thought of one.
Anyway, don’t there be arrow towers in both the inner and outer cities? And they will definitely continue to be built in the future, until there are arrow towers erected in every corner of the inner and outer cities.
The most troublesome thing now is that when the insect tide comes, because the number is too terrifying, the arrow tower cannot completely block all their travel routes. A large number of insects will definitely be put into the city, and archers will need to participate in the battle to clear them out.
What if we build a layer of protective net on the periphery and in the sky? It can not only intercept insects, but also allow the arrow tower to attack insects through the gaps! Moreover, the protective net can be powered on and turned into a power grid, making the insects die faster!
Under normal circumstances, this kind of idea is difficult to realize, and it will definitely require terrible human resources and precise planning.
However, Jia Zhengjin, who owns a game system, said it doesn't seem too difficult, right?
In the furnace, iron ore can be used to smelt barbed wire, and there is also a strong iron guardrail. He can use barbed wire to surround the outer city wall, and then build it above the city to form a super large roof of barbed wire. Use a strong iron guardrail underneath.
Make a circle and wrap the entire city.
After the power is turned on, except for the four city gates, which can be freely entered and exited, all the upper and lower gates are blocked!
The power grid and electric guardrail can isolate any flying troops from outside, preventing them from entering the city! However, there is also a disadvantage, that is, the flying troops in your own city cannot enter and exit at will. If you want to bring Warcraft, fake dragons, etc. into the city, you can
It can only pass through four huge gates.
Of course, if it can make the city safer, it's totally worth doing!
If you really have to pull up a protective net, the electric net and the defense of the arrow tower are enough to isolate any air attacks. It can also cause some trouble to the enemies attacking the city. Although this is part of the trap, killing insects is inexperienced for you.
Bonus, but safety is much more important than experience! All you have to do at that time is to make some repairs to the damaged iron guardrails and barbed wire! How simple? Just take a look with a hammer and it's OK!
Just do it as soon as he thinks of it. While everyone was going back to rest and sleep, Jia Zhengjin worked hard all night in the factory. First, he made all the complex parts for making the generator set, and then brought them to the tool table to start assembling.
As for the furnace, smelting began to make barbed wire.
By the time he successfully assembled a complete thermal power generation unit, there was already a lot of barbed wire in the furnace. He immediately took them out and hurried out to install them.
The iron guardrail cannot be built for the time being because the required iron ore is too much and the resources cannot keep up. We need to wait for news from the mine!
He first built four towering pillars in four directions of the inner city. The pillars were made of wood, but were not very strong. Then, using the pillars as supports, he installed barbed wire flatly in all directions, creating a barbed wire roof over the city.
Of course, Buddy's flying monster Kuru was borrowed for the whole process, otherwise who could build it at such a high place?
