Li Hanlin placed two seats directly, hesitated for a moment, and placed them behind the whistle cannon.

In fact, in a few more hours, Li Hanlin's basic optics will be completed. At that time, he can build another defensive weapon, the prism tower.

Although the range of the magnetic storm coil is 5 kilometers, the damage cannot satisfy Li Hanlin.

Howitzers on machine gun turrets, plus the damage of shells, can reach 250 or regional range damage.

The damage of the magnetic storm coil is only 150 points, and it is still a single unit, and it requires 10 units of energy for each launch.

Even if it is only based on the energy and materials ratio of the seawater refinery, 10 units of energy are worth 150 units of materials. You can buy 3 rounds of 100mm howitzer shells.

The attack speed of the magnetic storm coil is once a minute, probably because of energy storage, so there is no advantage.

The only thing worth mentioning is probably the last sentence, which can increase the damage and range of the magnetic storm coil through magnetic energy improvement.

However, Li Hanlin was confused by the way to improve magnetic energy. The only thing he could think of now was to continue to improve electromagnetics.

He also tried to directly supply the energy of the magnetic energy reactor to the magnetic storm coil through the substation, but after passing through the substation, the magnetic energy reactor has been converted into the purest energy.

This energy cannot increase the damage of the magnetic storm coil.

However, after all, the cost and construction time of the magnetic storm coil are much less than that of the machine gun turret, so it can still come in handy at this time.

But Li Hanlin did not build more. He only filled all four building sequences. After being lined up on the edge of the beach, he did not continue to build.

For safety reasons, Li Hanlin did not stay on the beach for too long. After asking Wang Shiyu to organize the evacuation, he also took the queen and the others to leave.

The dark clouds in the distance were still slowly moving closer toward this side.

As for the group of seagulls, after eating and drinking, they were infected by Wang Shiyu again, and their emotions had stabilized.

They also choose places, but they actually chose to settle down in the fortress, which is located on the eaves on the fourth floor.

Seeing these sea swallows busy and flying in and out, Li Hanlin's gloomy mood also improved a lot.

In fact, it was not just him, even the survivors who moved were much more happy when they saw this group of swallows.

They had just used to living in the villa, but now they are going to move into the supermarket again in a blink of an eye, where they don’t even have a bed, so they can only use the floor.

Although it is for their safety, no one will complain, but they must be in a bad mood.

News also came from the Apocalypse, saying that the rescue operation had made great progress.

Under the cover of the heavy-mounted robot that is not afraid of death, the mobilization team and patrol team have occupied several floors on the top.

Now the survivors have begun to be transferred. At this time, Apocalypse does not want to evacuate yet.

After hearing this news, Li Hanlin did not force himself and observed the movement speed of the dark cloud. It was estimated that it would be difficult to get close until the night.

After several magnetic storm coils were built, basic optics research was also completed. Li Hanlin took a look at the properties of the optical prism tower and built a light prism tower near the magnetic storm coil without hesitation.

[Light Prism Tower]: Long-range defensive building, construction requires 3,000 units of materials, and takes 2.5 hours.

Damage: 150 points/10 unit energy (5% of basic optical)

Range: 6km

Rate of fire: 1 time/minute

Note: Within the range, every light prism tower exists, it can provide energy accumulation for the main launch tower and strengthen 10% of the damage of the main light prism tower.

During the power accumulation period, the power accumulation prism tower cannot be emitted.

The prism tower costs 500 units of materials more than the magnetic storm coil, and the construction time is more than half an hour. The damage is the same as the magnetic storm coil, but the range is one kilometer longer.

Don't underestimate the distance of this kilometer, which means that I can hit you, but you can't reach me.

After the basic optics bonus, 10 points of energy can still only cause 157.5 single-body damage, but if you add one extra prism tower, this damage can be increased by 10%.

Moreover, the accumulation of power is the prism function of the prism tower itself. Li Hanlin didn't know what the principle was, and he didn't need to consume extra energy anyway.

Theoretically, if he built thousands of towers within the 6-kilometer range of the tower, the energy emitted by the main tower every time it was emitted may reach a very exaggerated level.

However, the range of the prism tower is only 6 kilometers, and it seems a bit unprofitable to build hundreds of seats and hundreds of thousands of supplies.

Moreover, Li Hanlin did not believe that this kind of improvement was unlimited, but it was not mentioned in the system description. The actual situation depends on actual combat performance.

In addition, other prism towers that accumulate power for prism towers cannot be shot. There are also hundreds of prism towers, and the power of radius towers is extraordinary.

After the light prism tower was built, Li Hanlin even looked forward to the arrival of the dark cloud so that he could try the power of the new weapon.

Whether it is a prism tower or a magnetic storm coil, it can be continued to be upgraded. Upgrading can not only greatly increase the power, but also significantly increase the range.

However, upgrading them requires continuing to improve electromagnetics and optics, but the time it takes to upgrade them is ten times as long as it was.

Fortunately, Li Hanlin's energy balance is now enough to cope with the full power consumption of the combat laboratory.

After the upgrade tasks of the combat laboratory are arranged, the efficiency should be improved.

But after learning basic optics, Li Hanlin chose to study basic mechanics. He has longed for mobile bases, especially after seeing this floating island today.

Because, he seriously suspected that the island was not formed naturally.

I think it is clear that even if nature has islands that can float, it is impossible to carry dark clouds with you.

The combination of these two even allowed Li Hanlin to directly eliminate all the zombies.

The ability of dark clouds and the ability to control islands cannot be mastered by ordinary zombies, and should be at least three or four mutated zombies.

However, it is impossible for these zombies to build strange buildings on islands, which are also significantly different from the modern architectural style.

One thing Li Hanlin could think of now is the so-called evolutionist.

Although the system said that the evolvers were in a deep sleep, Li Hanlin believed that the system would not lie, but the system did not say that they would not have subordinates, even Li Hanlin had subordinates.

Of course, although Li Hanlin suspected that he was an evolutionist and his subordinates, he still thought of another possibility.
