By the time I got back to the base, it was already night.

Opening the gate of the base, Fang Hao went in alone first, and after sealing the entrance to the fall trap in the passage, he let everyone in.

Tang Dandan's mood along the way was very complicated, she was still a little afraid that she would be a corpse at first, but after a few hours, her fear turned into indescribable joy.

Being infected without being transformed means that she will become an evolutionary.

For years, her siblings had longed to become evolutionaries like their father, but this was something that could not be met, and she had grown to lose hope of it.

But who knew that when he came to Fang Hao, it would be so simple to become an evolutionary!

She felt like she wouldn't be able to sleep again tonight.

After dinner, Fang Hao locked himself in the workshop and began to produce machine gun turrets.

If you want to make a machine gun turret, you need a lot of accessories, and it wasn't until this time that Fang Hao found out that before that, he also needed to unlock another weapon, the 12.7mm machine gun.

The unlocking of the 12.7mm machine gun requires 100,000 energy, that is, 10,000 crystal nuclei, plus the energy required to unlock the turret, the 100,000 crystal nuclei just taken from Loulan City immediately decreased by 30,000.

Unlocking the motion sensor, which requires 10 skill points, unlocking forged steel, which requires 5 skill points, unlocking 12.7mm machine gun bullets, which requires 5 skill points, and the 80 skill points he has saved now have 60 points left.

There are still many things that need to be unlocked with skill points, so Fang Hao has been saving skill points and didn't dare to use them.

The fort requires the strongest forged steel, which is also considered a building material, a key defense, and a castle gate, and if he has enough pig iron, he can even upgrade all the walls to forged steel.

At the same time, forged steel can also be used to make more durable tools, such as steel pickaxes, shovels, fire axes, and large equipment such as armored fighting vehicles, tanks, and even surface ships and fighter jets.

But for now, he can only build a few machine gun batteries first.

The machine gun turret also needs to use engines and batteries, and Fang Hao dismantled more than a dozen cars before and got some engines and batteries, which happened to be used at this time.

One of the benefits of the crafting system is that even dismantled cars can repair their own engines and batteries when they are added to the inventory.

Making a machine gun turret was much more complicated than making a gun, first he had to make pig iron into forged steel in a furnace, then make machine gun parts, make motion sensors on a workbench, assemble a special generator for the turret with an engine, make a strong and thick turret base out of forged steel, and make ......

According to the system, the automatic machine gun battery is all-weather, usually the battery provides it with a weak power, so that it is in a standby state, through the identification system of friend or foe, once it is found that there is an enemy invasion, it will immediately enter the combat form, at this time its built-in generator will start, to provide the battery with the required power.

He planned to build four automatic machine gun emplacements, each equipped with four magazines, each with 500 rounds, and four batteries were 8,000 rounds.

The automatic battery has a lot of firepower, but at the same time it is extremely ammunition-intensive, and these 8,000 rounds are definitely not enough, and he also needs to store a lot of ammunition so that he can replenish it in time when the battery is low on ammunition.

After the production of four turrets and 8,000 rounds of ammunition was completed, it was already midnight, Fang Hao put the four turrets in the inventory and walked out of the base.

Outside the base, Zitong and Ye Xiaomin each had a gun, and they were practicing marksmanship hard.

The three furnaces in the base attracted one Sadako girl after another, and their whimpering and howling one after another attracted the mad zombies roaming far and near.

Zitong was holding a rifle, Ye Xiaomin was holding a sniper rifle, the two of them were far away and one was close, and they cooperated very well, and the mad zombies were under their guns, and they couldn't get close to the base at all.

"Brother Hao, why did you come out? Haven't slept yet? Zitong said in surprise.

"I've got something to do here, you go ahead."

Zitong worked very hard to surpass Ye Xiaomin's marksmanship, and he didn't have a good night's rest as soon as he came back, so he began to practice marksmanship.

And Ye Xiaomin finally got Fang Hao's favor because of her marksmanship, she must seize this opportunity, she has already thought about it, and she will specialize in sniper rifles in the future. In order not to be overtaken by Zitong, she did not miss any opportunity to improve her shooting skills.

Under the sound of their gunfire, Fang Hao turned around the entrance of the base twice, carefully observed the terrain at the entrance, and finally found the four best locations.

After these four places are placed with turrets, the four turrets can support each other, and can also form crossfire in several important areas, as long as there is enough ammunition, no amount of zombies can get close to the base gate.

Fang Hao took out the shovel and cleaned up the place where the fort was to be placed, then put on the wooden frame, and then took out the wrench to upgrade the wooden frame to cast iron, and the cast iron to concrete.

It takes time for concrete to upgrade forged steel, because it is necessary to wait for the concrete to dry before it can be upgraded.

However, this did not affect his ability to place the turret.

A majestic automatic machine gun turret appeared very abruptly on the concrete platform.

Its huge body, thick and long barrel, almost like a small monster.

However, it didn't fire immediately, because Fang Hao hadn't turned on the switch yet.

"Wow! Brother Hao, what is this? Although Zitong was shooting zombies, she had been observing Fang Hao, and when she saw a turret suddenly appear, she couldn't help but scream.

"Come here, I'll tell you how to use it."

Zitong and Ye Xiaomin ran to the fort and looked at the monster in amazement.

"Look here, this is the switch, if you don't want it to help you fight zombies, just turn it off, you usually have to turn it on, it can automatically distinguish the enemy, and then automatically attack ......"

"Wow! So magical! Are you saying that even when we're not there, it can keep its home? ”

"Of course! Also, if you look at it again, this switch is up and it shoots, it will stop every three shots, and then aim at the next target, and then fire three more shots, if you turn the switch down, it will be burst mode, it will keep shooting enemies until all the enemies are dead or the ammo is exhausted. ”

"Really? Brother Hao, can you give it a try? I want to see how it shoots. Zitong can't wait to see how it works.

"Tomorrow, at night, it will wake people to sleep."

The machine gun battery was noisy, and its gunfire could be heard very far at night.

"Oh, that's a shame, tomorrow will be tomorrow." Zitong was a little disappointed.

Fang Hao asked the two of them to continue to practice marksmanship, and he was also busy for more than half an hour before he finished placing all four machine gun emplacements.
