Three days later, the surface base has been built, and now it's time to move down. Zheng Hao's idea was to use the North Pole as the center of the surface base, and build the base vertically downward, with a total of ten floors, each of which was initially 40 square kilometers, and each layer was separated from the upper layer by 100 meters, and the middle was connected by a pillar of a square with a cross-cutting area of 100 square meters.

Of course, this pillar can't support the weight of the base, it only serves as a connection and fixation, and what really supports the weight of the base is the anti-gravity device on each floor of the base. In addition, the ten-story base is connected by directional space wormholes scattered in all directions of the base, which can ensure that the base will not be instantly invaded into the main control room, even Zheng Hao can only reach the bottom of the base through the wormhole layer by layer.

In the ten-story base, the first layer of the base is on the surface, which is mainly responsible for the defense of the base, security robots, and defense laser cannons are all on the first floor. The second and third floors serve as military garrisons for the base, and if they cannot control the world by peaceful means in the future, then they will have to use the means of war. These two layers are stationed with Zero War Robots, but these two layers are only newly built, and they need to continue to expand in the future, and even connect the two layers, otherwise how can an army that can be stationed in just forty square kilometers control the world.

The fourth floor is the arsenal, which, again, needs to be expanded, otherwise the armaments will definitely not be enough. The fifth layer is an armament factory, although it can't make any super-large weapons, but it is still easy to rule the earth in this era. The sixth layer is the base's civilian materials warehouse, in addition to the base's own consumption, it is also a warehouse for selling materials to the outside world, Zheng Hao still doesn't want to go to war, and if he can use other means to grasp the lifeblood of the earth, he will never use war means. The seventh floor is a factory for the production of civilian materials.

The eighth floor is the energy collection center of the base, where the materials collected through the space wormhole are converted into energy, so as to obtain the building materials, materials and energy needed for the construction of the base. The ninth floor is the command center and research room of the base, bioHomo sapiens have begun to create, these bio-Homo sapiens do not have any emotions and six desires, the only desire is to work and research, and the lifespan is not long, only ten years, but they can also exist by cloning before death.

Because in addition to having a human body, they also have a biochip in their heads, take out the chip of the dying Homo sapiens and install it on the new Homo sapiens, then the new Homo sapiens will always exist as a dead Homo sapiens, and there is no death record in the brain, they will only think that they are just in a coma for a while.

Although these Homo sapiens are very flawed, they have been instilled with the knowledge they need when they are created, and it is still okay for them to do maintenance and research work in the base, so Zheng Hao always has three hundred Homo sapiens, which is also to prevent Tianxuan from being too lonely in the base alone, and if there is a need in the future, Tianxuan can also batch produce the Homo sapiens professionals he needs......

Finally, the tenth layer, the tenth layer should reach a thousand meters below the sea surface, and, in view of the low temperature of the Arctic Ocean, the temperature of the tenth layer should reach minus 70 degrees Celsius, but such a low temperature is the limit that Zheng Hao can withstand at present, staying in such a low temperature for more than two years, the true qi in Zheng Hao's body will definitely be able to regain balance, and maybe it can break through.

Do a good job, through the processing of the temporary factory in the past few days, Zheng Hao's construction robot has exceeded 10,000, and it is estimated that the main frame construction of the base can be completed within three days, of course, Zheng Hao's order is to give priority to the construction of the tenth layer of the base, after all, it will be used in four days.

Subsequently, Zheng Hao began to obtain the management authority of SAO, although Zheng Hao is not interested in slowly playing upgrades, but with Zheng Hao's current strength to run in, those monsters are estimated to only be killed in seconds, and now what Zheng Hao lacks is the comprehension of his own martial arts, in SAO, in addition to the last must-kill Kayaba Jingyan, Zheng Hao needs to have a combat perception with the bosses of all layers, and even if there is a chance, Zheng Hao also plans to directly blow up a hundred floors, so in the end, Zheng Hao still retains the experience system of killing monsters and upgrading.

What's interesting is that there is no point system in SAO.,It's automatically added with the player's combat habits.,Anyway, every level up,There are five points.,According to the player's combat habits, it's divided into strength、Speed、Endurance、Physique is automatically added.。

After that, Zheng Hao turned off his own combat skill system and retained the auxiliary skill system, Zheng Hao honed martial arts, if he retained his combat skills, how could he practice martial arts. In the end, Zheng Hao adjusted the pain system to 100 percent, and pain is also a part of cultivation.

After making all the preparations, Zheng Hao waited for the tenth layer of the base to be completed. On the afternoon of the fourth day, Zheng Hao entered the cultivation warehouse, the cultivation warehouse is the same as the learning warehouse, there is a life circulation system, after all, it has to lie down for two years, the difference is that after the cultivation warehouse is activated, it will sink outside the base, so that Zheng Hao's body can absorb the cold qi from the outside world to balance the drought essence in the body. In the cultivation warehouse, Zheng Hao ordered: "Start!" ”
