Ye Yan looked at the Thunder Defense Tower in front of him, which was more than twenty meters long, and finally breathed a sigh of relief.

Although making the Thunder Defense Tower is much simpler than a combat suit or something, the Thunder Defense Tower he wants to make is a giant defense tower with a height of more than twenty meters, and the amount of work is naturally very large, and it actually took him so much time.

Looking at the Thunder Defense Tower that was very wide and stable at the bottom of his eyes, gradually becoming smaller upwards, and finally set the color when it was completed, Ye Yan was still very proud.

Because, the first time he made the Thunder Defense Tower, the color was actually green!!

This green is not pure green, but on top of the metallic silver of the Thunder Defense Tower itself, with a faint layer of green, it is relatively good-looking.

Otherwise, a tall tower with all green is really unsightly to think about.

Ye Yan knew that although the green color on this Thunder Defense Tower was not very obvious, it was a real green-level weapon!

The Thunder Defense Tower is a device that combines defense and offense, and as the saying goes, offense is the best defense.

Near the tip of the Thunder Tower, there is a small platform that can be used to reconnoiter the enemy from a high place, and there is also a place where the Thunder Tower can aim and attack, which is also the operation point of the Thunder Tower.

And the tip of the Thunder Defense Tower is a divergent machine, and it is from where the terrifying energy attack is issued!

It not only serves as a cannon port, but also serves as a way for the Thunder Towers to absorb the power of Thunder in normal times.

When Ye Yan got the blueprint of the Thunder Defense Tower, and roughly had the shape of the Thunder Defense Tower in his mind, he was very strange.

Because the top launcher, which is also an absorption device, is a groove that is not big or small, unlike the metal texture, which is very strange, and the shape is exactly the same as the magic crystal!!

Coupled with the concave design, Ye Yan had to make a bold guess, could he put the magic crystal in?

Because the moment he got the drawings, Ye Yan had this kind of conjecture, so just now he put a magic crystal into it as soon as the Thunder Defense Tower was completed.

But as Ye Yan expected, it was not so simple, and the Thunder Defense Tower did not have any reaction.

That's right, it's impossible for a purple-level blueprint to have the power of magic crystal energy, maybe it's just a coincidence......

Ye Yan stood on the console below the launcher at this time, carefully studying the console.

The entire Thunder Defense Tower, which is very large below, has a very stable territory, and the higher it goes, the thinner it becomes.

To the top emitter, it is already a top point, which is very convenient for gathering energy efficiently.

And not far below the launcher, there is the console.

It's also very high, almost close to the top position, about seventeen meters or so of the Thunder Defense Tower, the view is very good, and the space is the size of a relatively large toilet, and it is no problem to accommodate five or six people.

On this console, there are machines that allow the launcher to be aimed at a specific position, as well as machines that monitor the entire field of view of the Thunder Tower, which is equivalent to a peacetime monitor and Skynet.

A Thunder Defense Tower that can almost put the entire Cool City under its monitor!

It is also because of these built-in monitors, even if no one is operating, the Thunder Defense Tower can automatically target and attack in crowded places.

In the operation console of the Thunder Defense Tower, you can have a panoramic view of almost the entire situation in Liangcheng.

There is also a special device in the console, which is used to store the energy of the Thunder Tower.

The green level of the Thunder Tower, a total of 10 blocks of energy.

Each bar represents how many thunder attacks the Thunder Tower can unleash.

The green-level thunder defense tower made by Ye Yan this time has a total of ten grids, that is, in the state of full ten grids, a total of ten thunder attacks can be issued!

Ten squares is also the upper limit of the energy that this Green Thunder Tower can store.

If only one of the power bars in the console are lit, it means that the type tower can only perform one Thunder Attack.

There are two ways for the Thunder Tower to store energy, one is to store the power of thunder and lightning in nature in normal times.

One is that the Thunder Mage takes the initiative to inject his Thunder Power into the Thunder Defense Tower for storage.

The emitter on the spire is also a reserve device, which can absorb the power of thunder in nature.

In the last days, the weather is unpredictable and very bad, and about one day out of ten days is thunder and lightning, so it is not difficult to rely on the power of nature to store the power of thunder.

But if the war comes very suddenly, and the Thunder Tower does not store enough energy, or can only fire a few hits, then the Thunder Mage can be allowed to inject the power of thunder into his body.

However, this method has many drawbacks during the war.

Because the thunder mage is an important combatant, injecting most of the thunder power of his body into the thunder defense tower is equivalent to weakening his own combat effectiveness, which is not a way after all.

The best way is that when the thunder mage is usually fine, he injects the thunder power in his body into the thunder defense tower from time to time, and the injection does not need to be too much, as long as he thinks about it when he is in a good state, it will not affect the thunder mage's own state, and it can also make the thunder defense tower fully charged quickly.

And about how the Thunder Mage injected the power of thunder into the Thunder Tower.

In the entire Thunder Tower, there are two places where Thunder Mages can infuse their own Thunder Power.

One is at the bottom of the tower and the other is inside the console.

Although he knew these basic things, Ye Yan, who made the Thunder Defense Tower for the first time, didn't know how much thunder power he had to inject into it in order to fill a grid of energy.

During Ye Yan's careful study of the Thunder Defense Tower, the people in Liangcheng at the bottom of the mountain couldn't wait to go up the mountain.

After a while, Ye Yan heard the sound of commotion.

Among them, Qi Fan ran the fastest and was the most excited.

"it!! Walked in to see it, it's even more awesome!! Qi Fan said excitedly, both eyes shining.

Wu Wu looked at the tall Thunder Defense Tower with adoring eyes: "The boss is worthy of being the boss!" Only a boss can make something like this! ”

Hu Haitao was also extremely shocked at this time, looking at the Thunder Defense Tower with a trace of green light: "Fortunately, I took out this thing with a cross of my heart at that time, otherwise it would really be a tyrannical thing!" Only Boss Ye Yan can make such a perfect Thunder Defense Tower! I actually succeeded the first time I did it! ”

Xu Gan also admired it from the bottom of his heart: "And it's the first time that I have made a green-level Thunder Defense Tower!" Sure enough, it's our boss!! Awesome! ”

Wen Yuannan, who had been working hard to recover his mental power and regenerate skin tissue for Wang Yu and Zhang Aoran, also temporarily put down his work at this time and came to take a look at the new gadgets created by Ye Yan.

I didn't expect it to be more shocking the closer I got!

If Liangcheng is guarded by this kind of thing in the future, they will be more at ease!!

Lu Wan's abdominal injury was almost over, thanks to her three-star evolutionary physique and Wen Yuannan's treatment.

Her eyes were full of excitement, because she was watching their Liangcheng base become better and better day by day, day by day becoming more and more like a base, day by day being more and more able to protect them better!

Zhang Yuru was still holding a roasted sweet potato in her hand at this time, and her other arm was still empty.

But she wasn't in a hurry.

Wang Yu and Zhang Aoran's injuries are more serious than her, and Huang Yanxing is such an important person to the boss, although Hu Haitao is missing an arm like her, but in her heart, Hu Haitao's combat effectiveness is higher than her, and Hu Haitao should be treated first.

Zhang Yuru looked at the mighty thunder defense tower that rose out of thin air, and her eyes were actually a little red.

Thinking of the tragic encounter that happened to her in the last days, she spent all her luck to meet Ye Yan and his party and save her from the dire situation, so she vowed to be loyal to this group of people for the rest of her life.

At this time, seeing that their base was growing step by step, an unprecedented sense of peace of mind, and a sense of steadiness in the last days, made her extremely moved.

Fang Yuanyuan and Zhang Yuru walked closer, and at this time, seeing that his good sister was a little out of control, he grabbed Zhang Yuru's shoulders and didn't say anything.

Ji Wenyu said with a smile: "It's still the boss!" I can't even admire it! ”

Ye Yan also said with rare modesty: "What are you talking about, we all see your contribution to everyone's base!" If it weren't for you, we'd be sleeping under a tree at night!" ”

The two-star warriors of Liangcheng further deepened their sense of belonging to Liangcheng at this time.

Every day, they feel the reliability of this boss.

Even if there are some battles, some sacrifices are inevitable.

But this is the end times, isn't it?

They are already better off than most of the other forces.

At least Ye Yan will give them any resources fairly, and will not squeeze them.

For example, when they went out to hunt zombies and mutant beasts today, most of them have not experienced real battles or real life fights.

But the core members are protecting them, on the basis of training them, on the basis of training them, they must protect them from serious injuries!

Like other forces, whether they are big or small, they all treat the lives of their subordinates like mustard, forcing them to go out and kill zombies to earn magic crystals, and they don't care about their lives or deaths.

Just today's one-day experience is enough for them to die for Liangcheng and Ye Yan!

Usually he cultivates his spiritual power very hard, and everyone sees that he is either cultivating his spiritual power, or Zhou Sheng, who is serious about the vegetable leaves on the ground, and it is rare for him to appear in front of everyone at this time.

He looked at the Thunder Defense Tower in front of him with some excitement, his eyes were full of yearning light, and he muttered, "This is my homeland, our apocalyptic homeland!" I will definitely do my part to make it even better and stronger!! ”
