But at least for now, what Li Mo should do is not to study the question of where the clues are, but to sleep! After all, it's almost eleven o'clock at night, and if you don't sleep, if you invite the zombie horde, they ...... At least Li Mo should have cried.

Well, in fact, Li Mo really cried and returned to the game world. By the time they had completely found a place to lie down, it was almost half past eleven, and Li Mo had at most closed his eyes and squinted for a short while, and then he was woken up by the alarm clock again, and then he was teleported close to the game world.

As soon as he thought that tomorrow would be the tide of corpses, in order to meet the tide of corpses, Li Mo couldn't sleep properly for twenty-four hours in the game world today, and he felt dizzy for a while.

But thinking about the success rate of negotiating with zombies and getting them to postpone the date of the corpse tide by one day, well, Li Mo gave up decisively. Bear with me, get to work!

Anyway, Li Mo has too many things to do today, first of all, he needs to strengthen his house's holes, combat platforms, small platforms, and various load-bearing columns to the concrete level as much as possible.

At the same time, he also has to unlock the skills of the steel craftsman as soon as possible, and then whether it is to make steel weapons and tools, or to reinforce the buildings in important parts into steel-clad concrete blocks, it can greatly increase Li Mo's chances of surviving in this world.

In addition, on the sand next to his combat platform, at least four corners need to be covered with a layer of haystacks. Because of that thing, the next time Li Mo feels that the combat platform can't hold it and needs to jump off the building, he won't have to worry about breaking bones if he jumps on it.

Moreover, Li Mo has been planning to modify some unreasonable small details of his combat platform, and build a maintenance platform five meters above the ground.

This work is a very important thing, as long as he has this maintenance platform, Li Mo can repair the building blocks that have been scratched by the zombies in time. With sufficient repair materials, the service life of his combat platform will increase indefinitely.

In the end, Li Mo felt that he should also prepare a long-handled melee weapon for his teammates, such as a spear.

Therefore, after listing so much work, even if Li Mozhen's head is a mess now, he can only cheer up.

In order to advance the pre-skill technology of the steel craftsman, Li Mo threw all the aloe vera he had harvested during this time into the manufacturing column and began to produce aloe vera paste. And he himself rushed to the hole.

Because of yesterday's dog tide, there are now countless animal skins in Li Mo's family. So Li Mo directly made four more furnaces, completely separating the work of the furnaces.

In the future, everything made from scrap iron was fired in a furnace, everything from lead was fired in a furnace, and the same was true for scrap copper, fine sand, and stone.

As a result, the efficiency of the furnace has increased several times over.

Not only that, Li Mo also went to the system store to buy materials and made a workbench and cement mixer in the hole of his home. In this way, with the cement mixer in the camp of the system store, Li Mo's concrete parameters have doubled, not to mention, when he can't enter the system store at night, he can still use the workbench and cement mixer in the hole of his house.

With all this in order, Li Mo had five furnaces smelt the raw materials they needed at the same time, and returned to the ground again to begin to transform his family's combat platform.

In fact, it's easy to add a maintenance platform to his combat platform, it's nothing more than to build a platform at a height of five meters for him to stay, and then dig a hole in the ground of the cabin on the combat platform and put it on a ladder.

At most, at most, add a wooden hatch on top of the ladder to prevent zombies from rushing in.

I don't know if the zombies are all on vacation today or they are all holding back their energy and waiting for tomorrow to form a group to brush Li Mo's explosive equipment, anyway, for a whole morning, Li Mo also cleaned up three or two lonely zombies piecemeal, and no zombies came to trouble him.

By noon, Li Mo's scientific and technological skill level had finally been brushed to the third level, and the conditions for unlocking the steel craftsman had been reached.

After fifteen skill points were spent, Li Mo's mind immediately had a lot of knowledge about steel and steelmaking. There was no nonsense, Li Mo immediately rushed back to the cave in his house.

In fact, as early as when making the workbench and cement mixer, Li Mo made plans for upgrading the steel craftsmen. At that time, when purchasing raw materials, he not only bought the raw materials that he would definitely use to make crucibles after learning the steel craftsman, but also bought the die tools that were necessary for another kind of furnace.

At this time, the steelmaker Li Mo had already learned, and after a morning's work in the furnace, a lot of raw materials had been accumulated, just waiting for Li Mo to put the crucible and die tools away, and he could produce all the items that the furnace could produce.

"Forty pieces of cast iron, ten pieces of mechanical parts, one thousand two hundred pieces of small stones, and nine hundred pieces of clay, I really don't know how big this crucible will be, and how much raw material it will need." Li Mo was babbling as he threw the materials needed to make the crucible into the crafting column of the workbench.

Then he himself was not idle, and immediately went to the two furnaces that used scrap lead and scrap copper as raw materials, and made all the materials in the furnaces into warheads and eggshells.

Li Mo's own rapid crafting skills have reached the full level, so now he is making warheads and bullet shells and other bits and pieces, and the speed is simply fast. Just listening to the sound of "bang, bang, bang" in the furnace, Li Mo knew that it was estimated that he would not be short of bullets for a long time in the future.

After a little more than an hour's effort, all the scrap lead and scrap copper reserves of Li Mo's family have all turned into brand-new warheads and cartridge cases, and Li Mo's gunsmith skills have also been rushed to the peak of the sixth level by him in one go, and with a little more proficiency, he can become a veritable master of gunsmithing.

However, for Li Mo, this is not enough! His goal is to be a master of firearms! Because only by reaching the level of a great grandmaster can Li Mo better grasp the various details of firearms, so that the weapons he makes can play a better role.

After all, when they were on Earth, they had already encountered a second-evolution zombie, and no one knew what level the zombies on Earth had evolved to. However, Li Mo already felt that it might be a little difficult to deal with higher-level zombies just by relying on crossbow arrows, so he needed to plan for the future of his teammates in advance.
