In the dim underground space, Wang Zi woke up on time the next day.

After waking up for a moment, he realized that he seemed to have discovered another hidden setting.

That is, as long as it is the underground space you have created, you don’t have to worry about the air at all.

This setting is actually very obvious in the game. Even if you come underwater, the air strip will continue to consume, and blood will be lost after consumption. But you just need to build a block underwater and then dig a space inside, the air strip will disappear, and the player will not lose blood if he stays inside for no longer.

Now it seems that this setting is indeed the same as other things, and has been inherited by myself. This is fine. In the future, there will be no problem except going to heaven and earth, and going to the sea.

Wang Zi drank half a bottle of water again, moistening his thirsty throat. Although drinking water can only replenish his satiety, and eating can replenish his food even more. As long as he doesn't lose all his satiety, he will not have any trouble. However, if he doesn't drink water for a long time, he will feel uncomfortable and his mouth will also dry, which will affect his speech. So Wang Zi still drinks water from time to time.

In this way, I don’t have much mineral water reserves. Although I still have many buckets (washed transparent cooking oil barrels, and I like to use this bucket to fill rice and water. It can be lifted and has a lid, which is very convenient). Clean water is stored, but finding a new water source to complete the main task 4 is also something that must be done as soon as possible. This is actually very easy, just go to the riverside.

In this case, you still have to return to the ground.

Looking at these, Wang Zi took out a roast wolf steak made by the chef on the fire and took a few bites.

Not to mention, the wolf meat steak roasted by the chef from the fire is really great, it is not as fishy as imagined. It is mainly the ingredients of the wolf meat hit by the hammer, just a large piece with almost no bones, and looks perfect. Then, after being automatically roasted by the fire, a fragrant crispy wolf meat steak is out of the oven.

When Wang Zi tasted it last night, he almost swallowed his tongue. This meat steak tasted better than any meat steak he had eaten in the past. Unfortunately, the amount of meat steak was a bit large. After eating, his satiety level increased by 50%. After two points, not only was he full of food, but his stomach felt very supportive, which was quite powerful.

After replenishing his satiety, Wang Zi stood up and began to demolish the house where he lived.

After knocking out a piece of open space, he then took out the processing lathe from the inventory and began to study how to use it.

Although there was no electricity, there were a few tools that were found in that studio at that time that could not be used, but there were still many manual tools. So after Wang Zi studied it, he quickly understood the usage of these tools. Then he began to think about what he used to make a new sledgehammer.

"Well... If I have to say it, it seems that the parts on the car are the most suitable to make a sledgehammer in the things I got?"

So, Wang Zi simply chose the cheapest car from his many car collections and took it out and put it in front of him.

"Look at it... the shell is definitely not good, it's too soft, it can't do anything, pass. Tires? It seems to be a bit feasible, tentative. Axle? It doesn't seem to be useful, it's not straight. Well, what else... Oh, by the way, the engine! This weight is enough and the size is appropriate!"

Fully expanding his mind, Wang Zi quickly chose the most suitable target: the engine and axle.

Anyway, as long as it is a hammer, no matter what material it is made of, the creator can swing like a toothpick, so he doesn't have to worry about weight at all. It's better to choose something heavier than to choose. For example, the full metal hammer made in the later game, the hammer head is about the same size as the player's head. Although it is a Q-version character, it should actually be similar to the engine.

Thinking of this, Wang Zi made up his mind. He didn't hesitate and directly picked up the tools and started to dismantle the car.

Fortunately, the original complete thing, as long as Wang Zi does not use a sledgehammer or weapon to attack specifically, there will be no blood bars, which will prevent him from being able to disassemble it.

Without power tools, it is difficult to disassemble the car with some handheld tools alone. Fortunately, Wang Zi's purpose is not to repair it, so he just made a miracle. So after spending more than two hours, he finally successfully disassembled the engine he wanted.

With the hammer head, the next thing is the hammer handle. This is easy to deal with. There is a good steel pipe in this studio, and the length is also appropriate. It holds it very well and can be used as the hammer handle.

Assembly is a difficult problem. It is not easy to drill holes as big as the engine. Fortunately, there is a hand-crank hole punching tool. After Wang spent all his own efforts, he drilled the hole he wanted on it and inserted the steel pipe into it.

It was difficult for him to fix it. Without electric welding, it was obvious that the two could not be firmly combined. In the end, he could only think of a way, relying on pins and other methods to fix the two together. But in this state... it is hard to say whether they are strong or not.

"So, I really want a smelting furnace..."

Looking at the weird-looking "engine hammer" in front of him, Wang Zi was not very confident that this thing could be recognized by the system. He tried to knock this guy off with a big wooden hammer and then check its properties.

[Strange engine hammer: a shoddy hammer that doesn't seem to be very strong. It has strong destructive properties on the block, with an attack power of 100 and a durability of 20.]

"That's great, it's successful!"

Although the system's complaints seem to be less useful, and the durability of 20 is much lower than any weapon or wooden hammer in his hand, it is obvious that this thing was still recognized by the system.

At this moment, Wang Zi suddenly discovered that a new exclamation mark was displayed in the system interface taskbar. He clicked on it and saw that apart from the 50% main task 4 had been completed, he didn't know when a new task would be flashed.

[Side Quest 1: You seem to have noticed that the creator should be able to create the formula by himself. So try it out and invent a new formula with the materials at hand. Reward: "The creator is smart", 500 points of character experience. Status: Completed.]

[Creator is clever: add a custom formula bar for a universal workbench, and you can freely add materials to make them. The production results are randomly combined with the added materials to create a result.]
