There was no propellant, the pistol bullets were useless, and Su Tianzong had to put it down first. Since the firearms can't be used immediately, Su Tianzong can still print some cold weapons for self-defense. He picked out another good weapon from the three-dimensional model, which was the Hidden Blade.

This is a three-dimensional model of the Hidden Blade made by Su Tianzong when he played the "Assassin's Creed" series of games, according to the original drawing of the game setting. The Hidden Blade was originally used as a melee weapon in the Assassin's Creed games, and was primarily used for close-quarters assassination or combat, allowing for a surprise effect due to its ability to hide the blade in the sleeve. In the official commentary given by the game company, the development of the Hidden Blade in the game is divided into three phases, and its functions are becoming more and more powerful. The three-dimensional model made by Su Tianzong is the third generation of the Hidden Blade. The Three Generations of Hidden Blades refer to the Hidden Blades of Assassin's Creed 3, which made the traditional Hidden Blade into a one-piece dagger that could be rotated and held in the hand at will, making it much more practical, and it was the biggest breakthrough in the history of the Hidden Blade.

The construction of the Hidden Blade is much simpler than that of a firearm, consisting of multiple metal segments and a mechanism that ejects the blade, as well as a leather arm guard as a attachment point for wearing. The material of the main body of the Hidden Blade is actively set to titanium alloy, which is less weight than steel but has the same strength, and is more suitable for arm wear. It took forty-two minutes to print the entire set of Hidden Blades in 3D, more than a firearm, and the time spent mainly on printing the leather arm guards, which were made of faux leather fibers.

There are still a lot of good things in the warehouse, such as two sets of portable electromagnetic machine gun defense towers, but unfortunately Su Tianzhong's civilian identity cannot be used, and he must be a citizen to use this light defensive turret. Su Tianzong could only take out a set of basic welding and mining tools to take a look, these two tools were very similar to the tools that Su Tianzong saw on the corpse wearing the engineering exoskeleton, and they seemed to be some kind of important equipment. Curious, he picked up the basic welding tool to inspect it, and found that it was quite complicated.

"ZX" took the initiative to display instructions and animation tips this time: "The basic welding tool, an infrastructure tool invented by the Human Republic Starship Project Research Institute, is the highest scientific and technological achievement combining holographic projection technology, nanomachinery and three-dimensional printing technology. It is the core equipment for human beings to quickly build fortifications, ground bases, starship battleships, and space fortresses when fighting foreign enemies. The principle of the equipment is to use holographic projection to project a 3D model, and then use nanomachinery to transport materials and weld them, and gradually materialize the virtual projection building and ship module of the 3D model to create the required base and starship. How to use: The first step is to set the required building type, and the current types available are four categories: buildings, ground vehicles, small starships, and large starships. The second step is to select the required building modules, and the various building modules contained in each category can be freely combined into different buildings or ships, as long as you choose one. Step 3: Weld with a nano welding system, please bring enough construction materials. Please note: Nanomachines can only use materials preset for building modules, and living organisms cannot be used as printing materials. ”

Su Tianzong looked confused, and after thinking for a long time, he realized something: "Oh, so that's the case, I said how can those professional-level high-level survival freaks build mecha and starships by themselves, it turns out that there are such useful tools." I thought that these guys were all immortals, starting with iron smelting and ending with the ability to take care of the entire industrial system by themselves, and build starships casually. ”

"Your understanding is wrong, high-level survivalists also need equipment and supplies, it's just the level of means and skills."

"Means?"

"There is a big gap between professional-level survivalists and professional-level survivalists, according to the public survival competition records, the mecha made by professional-level survivalists can't even be looked down upon by the general army, and can only be used for logistics transportation or civilian combat competitions. The design of the professional-level survivalist is proficient in actual combat, and the mecha produced by it is rushed to buy by the military fleets of the major star regions."

"Ha, that's so bad. Aren't the basic welding tools all modular in design, how can there be such a big gap? Su Tianzong was a little puzzled, since they are all the same module design, the things made should not be much different.

"The welding tools that civilians can use are limited to the basic level, and only unarmed small buildings and civilian starships can be made. Citizenship is the only way to use the primary welding tool to create civilian-grade small light armed bases and light armed starships. The army can use mid-level welding tools to create large bases and large warships with heavy armament. Advanced welding tools are only available to elite armies and major fleets of pro-level survivalists and human republics, and can be used to build superweapons, interstellar carriers, and battlestars. ”

Su Tianzong was a little speechless, the word foundation of foundation welding tools turned out to be a restriction of identity, not the concept of infrastructure construction tools that he understood. Professional-level survivalists can build superweapons, and the mecha they build must be extremely sharp. There is definitely no comparison between the professional level, and it is not surprising that you can only build some civilian mechas.

He looked at the basic welding tools in his hand, and his heart was hot, even if it was just to build some unarmed starships, its technology would be more advanced than that of this world for dozens of generations. With just a starship, it will be possible to escape from this apocalyptic planet where a rift in space is about to occur. However, the reality is not so simple.

"ZX, how am I going to build a starship?" Su Tianzong asked eagerly.

"What kind of starship do you want to build? The types of starships that can be made with the basic welding tool are: small planetary atmosphere shuttles, small transport ships, small lifeboats, small passenger ships, small engineering ships, and small mining ships. In addition, the basic welding tool you use is a space shelter-specific version, which can design and build a small survival ship for escape, which can create a circular ecosystem and provide at least 500 people with the sustainable living environment necessary for space travel. ”

Su Tianzong didn't quite understand the law, so he asked, "Are there any restrictions on small ships?" Why can't you make a big one? ”

"The basic welding tool can only build small ships within 10,000 modules, and each hull module is ten cubic centimeters in size, and there is no limit to the size of the functional modules, but the interfaces of all pipeline lines are ten square centimeters. The primary construction tool can build medium-sized ships with less than 100,000 modules, each hull module is based on 50 cubic centimeters, and the interface is also 50 square centimeters in caliber. ”

"The identity of civilians is terrible." Su Tianzong had to complain.
