Although there is no additional gain in the attack of Apocalypse, the improvement of zombie corpses and levels is originally a kind of gain.

Except for the relatively low-level Red Lotus battle, which was upgraded to level 5 or 6, the others were more or less upgraded to level 1 to level 2.

After these corpses were collected by mining trucks, they could be converted into materials immediately. In addition, the assets of Tiansheng Island and mine caves were released, Li Hanlin's warehouse became full again.

That night, Li Hanlin urgently upgraded several warehouses to the top, along with supermarkets on Fuxing Island, Gate Cannons, etc.

After the threat of the sea snake, Li Hanlin had to pay attention to the protection of the shore. The level 5 Gate cannon was very powerful.

The original gun barrel was at least a few dozen mm thicker, and now it is 76 mm eleven giant cannons.

【Crazy Gaut Cannon】Level 5 dual-purpose defense building with open space

Weapon: Eleventh Connection 76mm Multi-tube Cannon

Damage: 155-180

Rate of fire: 120-300

Range: 20 km (ground) / 10 km (air)

Hit: 14

Ammunition: 16000

Ultimate effect: After the Gat cannon is crazy, the probability of critical strike increased by 50%.

The initial caliber of the Gate machine cannon is 23mm, called a cannon, but it is actually a gun. Its power is only a little stronger than the 20mm sentinel cannon. The most important thing is that its shooting speed is terrible.

Up to the top level, the materials spent on level 4 to level 5 alone exceed 10,000 units. Including all the expenses of the first 4 levels, it is another 10,000 units.

The 20,000 units of supplies are enough to produce two destroyers. The only advantage of the Gate cannon is that it does not take 24 hours.

Of course, after the second-level shipyard came out, it no longer took 12 hours for a destroyer, and it was reduced by 1.2 hours for each.

The original Gate cannon covers an area of ​​1*1, which is equal to 4 square meters of land, while the ultimate Gate cannon requires a full 100 square meters, which is equivalent to a three-bedroom apartment without a common stall, which is 25 times larger.

In addition to the increase in area, the height has also increased several times, as high as 4 or 5 floors. If the muzzle is facing the sky, it will probably have 6 or 7 floors.

With such a volume, most of the accumulated ammunition was ammunition, and the 16,000 rounds of ammunition also let Li Hanlin know where his supplies were spent.

However, the thicker barrel also caused a problem. The rate of fire of the Gate cannon has always increased in the first two upgrades, but the last two upgrades have negative growth.

At the end of the day, the rate of fire is not even as good as the first-class Gate cannon, and the first-class Gate cannon, the rate of fire is 320.

With 5 more gun barrels, the rate of fire has been reduced by 20. Not to mention ten thousand shots per minute, it is difficult for a thousand shots per minute. I am afraid that it will take until the final crazy state to reach the terrible rate of fire of one thousand shots.

But Li Hanlin was not angry at all, and was even a little excited. He was very much looking forward to one day when someone who didn't open his eyes would come into it and let Li Hanlin open his eyes.

There is no way, the Gate machine cannon is really too exaggerated. If you put such an ultimate weapon here, even the tank zombie Li Hanlin is not afraid of it.

It was so hard to fight tanks and zombies before, but the main reason was that ordinary weapons did not break the defense.

The damage of the main artillery of the Age can break the defense, but even if the Queen, Age, Lingkong, Yinyu and others are on the same side, the damage caused may not be repaired quickly.

After all, there were countless zombies around the tank zombies at that time, and they also had super recovery capabilities.

If it weren't for the concentrated high-explosion bomb that emptied the tank zombies and completely shattered its shell defense, I really don't know how long it would take to kill it.

But with this crazy Gait cannon, it's different. Even if the damage is not even comparable to Silver Feather's sniper bullet, it can damage close to 200 points and can already break the tank and zombies.

In a crazy state, thousands of shells hit a minute and smashed the tanks and zombies to death. Not to mention that after the crazy situation, there is a 50% chance of critical strike, so the damage is terrifying.

Of course, although the hit at 14 points has improved compared to the Gate cannon, there is still no hope.

It is impossible to hit every shot, but with the size of the tank zombie, it is more than enough to hit half of the shot.

The defense and vitality of the sea snake are not as good as that of tank zombies, nor does it have the perverted recovery ability of tank zombies, and the ability to quickly recover by swallowing flesh and blood.

Therefore, with such an ultimate Gate machine cannon, even if the sea snake quietly climbs onto Fuxing Island, it will definitely make it come and go.

In fact, what surprised Li Hanlin the most was the ultimate effect that appeared after the Gate machine cannon was promoted to the top level.

Don’t underestimate the explanation of this small line. This one alone is enough to increase the output of this Gate machine cannon by 50%.

Even if it takes a little time to be crazy, on average, it will have to increase by 30%.

If he had known that he would have upgraded the defensive building to the ultimate, he would have had additional special effects, so he would have been promoted to the top level long ago, so how could he have built so many sentry cannons?

‘It’s not too late to know now’ and after talking to himself, Li Hanlin held the Nightingale and took her to rest half forcibly.

In the next few days, Li Hanlin took a boat to Tiansheng Island for construction, mainly focusing on the upgrade of warehouses, magnetic energy reactors and supermarkets, and at most a seawater treatment plant was placed on the edge of the beach.

The electricity overflow on Tiansheng Island is now severe, so he cannot stay there all the time. If the warehouse is inflated, the magnetic energy reactor and other things will stop rotating, and the island will lose its power supply.

It is better to place some equipment to consume energy, and by the way, it can also reduce the cost of building islands.

The main function of Tiansheng Island is to maintain life, so only the necessary defense is added.

But Fuxing Island is different. Li Hanlin of Fuxing Island intends to be built into a mobile military fortress. Therefore, every inch of land on this island must be used, and no low-level building is allowed.

In the past few days, in addition to the Gate machine cannon, anti-aircraft artillery, Patriot missiles, and even sentry cannons, he has gradually upgraded to level 4. After waiting for a day or two, these buildings can be upgraded to the top level.

The main base of our home is walking on two legs, and two production lines are responsible for upgrading and building buildings, such as upgrading magnetic energy reactors and building refineries.

The other two production lines, one is busy upgrading the whistle gun.

This time, the upgrade of the sentry cannons is no longer the same as before, but it is upgraded one by one. The previous sentry cannons were not as high as the top level, regardless of other buildings.

Another production line will continue to upgrade shipyards, tank factories, and arsenals.

Not only does these buildings cost a lot, but the key is that they take up too long.

So after a few days of queueing, Li Hanlin's own fortress still couldn't line up.

The main reason for upgrading the fortress is that the evolvers are about to wake up, and Li Hanlin wants to be more safe.
