Back in the workshop, Fang Hao immediately began to experiment, he put 200 crystal nuclei and secondary crystal nuclei in the inventory, and then, clicking on the crystal nucleus with his mind, the option of synthesis appeared on it.

"Synthesize!"

The 200 second-level nuclei instantly became 190, and at the same time, there was an additional third-level nucleus in the inventory.

"Great!" Fang Hao was excited, he would be a self-propelled crystal nucleus synthesizer in the future.

He continued to synthesize, synthesizing 10 times in succession, and obtained 10 third-order crystal nuclei.

"Keep synthesizing!"

10 third-order crystal nuclei, and then become a fourth-order crystal nucleus.

This is so convenient, when you need a high-level crystal nucleus in the future, you don't have to ask for help.

In fact, for others like this low-level crystal nucleus, there is no need to synthesize at all, because synthesis requires a long journey, and the cost of synthesis must be very high, it is better to directly kill a few high-level mutant zombies, which may be more cost-effective.

But Fang Hao's synthesis didn't cost anything, and this manufacturing system was better than anything else.

It's a pity that the first-level crystal nuclei can't be synthesized, they can only be used to absorb as consumables, and in addition, these crystal nuclei can only be synthesized twice at most, no matter how high they are.

What made Fang Hao feel very excited was that it seemed that he hadn't discovered all the functions in this system, and maybe more functions would be discovered in the future.

"Brother Hao, I'm already a second-level evolutionary!" Zitong rushed in happily.

Fang Hao looked at her, and sure enough, whether it was her mental outlook or physical aspect, there had been a huge change, even her eyes were more agile, and her person seemed to be more beautiful.

"Not bad! Keep up the good work and strive to move up to level 3 as soon as possible! Fang Hao encouraged her.

"I will, Brother Hao!"

After Zitong finished speaking, she began to twist and pinch again, putting on a little appearance of wanting to talk, Fang Hao knew that she had to think of new ideas again.

"What's wrong?"

"Brother Hao, can you send me a sniper rifle?"

Zitong has never been left behind, and when she saw Ye Xiaomin practicing sniper rifles every day, she always felt panicked in her heart.

In fact, she felt that her marksmanship was also very good, if she was given a sniper rifle, she would not be much worse than Ye Xiaomin.

"Okay, as a reward for your promotion, I'll make an exception to equip you with a sniper rifle."

Fang Hao took out his sniper rifle and handed it to Zitong.

"The use of sniper rifles is very different from ordinary rifles, you just start practicing, you have to learn more from Ye Xiaomin, if after a while, I find that you have not improved, this sniper rifle has to be withdrawn."

Zitong hurriedly said: "I will definitely study seriously with Sister Xiaomin, don't worry, Brother Hao." ”

"That's good." Fang Hao was afraid that Zitong would be arrogant and unwilling to learn from Ye Xiaomin, so he deliberately said so.

For the next few days, Fang Hao still went to the mine to mine gold during the day, returned at dusk, and began to build houses after eating.

In the end, Fang Hao still chose the concrete structure, although this would waste some steel, but concrete is stronger than stone walls, and it can be upgraded later.

I have to say that Tang Dandan still has a set of planning aspects, she designed a number of horizontal and longitudinal stone roads according to the topography of the mountain, according to local conditions, these roads can lead to any house.

And each house is designed with a small living room, bedroom, bathroom, decent, and all kinds of furniture, although it has not yet been built, Fang Hao already knows that it must be very comfortable to live in such a house.

Because of security needs, the house does not have windows, but there are multiple shooting holes, and the shooting holes are equipped with glass, which is no different from windows, and when necessary, the glass is broken, and you can shoot out through here. The shooting hole is just the size of the zombie to get into, but the people inside can easily shoot out.

The laying of the pipeline, Tang Dandan believes that it is directly laid under the road, and the work of the pipeline is done by the way when the road is built, which saves labor and time.

"Look! Brother Hao is starting to build a new house! ”

"Look how fast Brother Hao built! In a few moments, a new house will be built. ”

Timo had a look of admiration on his face: "Brother Hao, are you an immortal?" Brother Hao, you must be a fairy! It's not an immortal, it's impossible to be immortal! ”

Several children gathered around Fang Hao to watch Fang Hao's magical performance.

Hu Zihua and other adults were busy practicing their driving skills outside, and these children couldn't grab them, so they could only come to watch Fang Hao.

"Who do you say, for this first house?"

"Your skull is broken, of course the first building is Brother Hao's!"

"Oh, that's great, I'm going to live in a new house soon!"

Fang Hao said at this time: "After the new house is built, it will take a while before you can live in it, otherwise it will not be good for your health, do you all know?" ”

"I don't know." A group of little ones said in unison.

"Just know later, okay, don't gather around here, practice your marksmanship well, and I'll give you a rifle later."

"yes, I'm going to have a big gun and a spear!" A group of children dispersed.

Because of the planning, Fang Hao must always compare it with the planning map when building the house, the length, width and height, and the location, and there can be no slight mistakes.

Every night he was busy until midnight, and the next morning they saw one new building after another. Although the cement of these houses has not yet dried, the style is very beautiful, and from time to time it attracts criticism from everyone.

By a few days, more than eighty houses had been built, filling a small half of the mountain, and all the houses were connected with pipes and wiring.

At this time, Fang Hao had saved enough gold in his hand, so he decided to go back and sell all the gold, so that he wouldn't need to go to the mine every day in the near future.

In the past two days, Zitong ran to Fang Hao's room every night to see if he had sneaked away.

That night, she finally waited for the long-awaited adventure, the adventure of another world.

"Take all the guns and weapons off of you, and we'll leave tonight."

Zitong didn't understand: "What? Take all the weapons down? So what if you're in danger? ”

Fang Hao smiled: "Normally, there is no danger, and ordinary people are not allowed to carry weapons there. ”

"No, it won't! Wouldn't it be a hassle if you encountered a monster! Zitong cried out.

For as long as she could remember, the weapons on her body had never left her body, even when she slept, and she couldn't imagine what it would be like for a person to go without a weapon.

"Go! Obey orders! Fang Hao grimaced.

Helpless, Zitong had to take off all the weapons on her body, including her hidden weapons that she didn't know where to hide.

In fact, until now, he is not sure if he can return to Earth with Zitong, he just wants to test it this time.
