Why do you choose to be on the sea?" Qin Siqi was puzzled, even before the end of the world, it was not easy to build a city on the sea, let alone in the current environment.

"Does Professor Qin remember the killer fish he encountered in the West Zhou River before?" Zhao Feng changed his words and brought up the old story.

Qin Siqi was stunned for a moment, then nodded, she naturally remembered: at that time, she was still the commander of the survivor convoy, and she wanted to take refuge in the military fortress, but she was blocked by the strange fish in the river of the Western Zhou River on the road, and she quarreled with Zhao Xue because of her misunderstanding of Zhao Feng.

"In fact, I spent a lot of time checking satellite surveillance in the morning and found something ......" Zhao Feng asked Xiao Hei to bring up the picture:

More than 20 meters above a certain endless sea area, a huge white flying shadow spans hundreds of meters of sea area, suddenly swoops down, and picks up a bull shark that floats out of the sea, but before the huge bird devours the bull shark, there are several waves on the calm sea, and its momentum is fierce, such as a vicious dog at sea, a monster of water, and swallows the white bird and the bull shark together!

After a while, the calm of the sea was stained scarlet with blood, and the blood attracted more fish, which ate the blood of the sea, and in the dense school of fish, a colorful and dazzling light could be faintly seen, and there was only one strange light on each fish......

"This has become the norm in the ocean, you should be no stranger to those brilliance, I speculate that the zombie virus has affected the vast majority of life in the ocean, this is a potential crisis, and the survivors are still fighting for survival on land, there is no time to take care of the crisis from the ocean, I built a sea city, one is not to fight with the survivors on land, and the other is to take the lead in preventing these crises, even if they can't deal with it, at least deepen their understanding of mutated sea creatures. Zhao Feng made the final explanation, and Qin Siqi nodded solemnly in agreement.

"If you do these things, no one will know about it in the short term, and even if the world knows about your efforts in the future, they will not thank you......" Qin Siqi looked at Zhao Feng with complicated eyes.

"Why should I be thanked? I only do what I want to do, and it's too tiring to live in the eyes of others. Zhao Feng waved his hand and said indifferently.

"Whew...... Okay, so how do we do that? We don't have a lot of people right now. Qin Siqi sighed and gave up speculating on Zhao Feng's intentions.

Without waiting for Zhao Feng to answer, Liu Yan rushed into the conference room with an excited face, shouting as he walked: "Boss! Those drones are so powerful! I was thinking of using my mental power to help carry the materials, but these little things turned out to be amazing! They started working quietly! From screws and nuts to furniture and farm tools, there was nothing that could not be moved, and those people in charge of the warehouse also tried to use their abilities to stop the drones, but they were all dodged! If you put some weapons on them, hehehe......

After hearing this, Qin Siqi understood it completely, and she even suspected that Zhao Feng left suddenly before, maybe it was to get these drones.

The "Sea Yitian City Creation Plan" was finalized at 11:17 p.m. on the same day.

At six o'clock in the morning of the next day, Zhao Feng removed the energy shield of the middle and outer layers, and the delivery of the drone overnight also completed the transaction with other forces at this time, and the nineteen military fortresses all expressed their hope to retain a portal to Wangfeng Tower after learning the role of the "two-way portal", Zhao Feng sold a hanging scroll of a set of two-way portals at the original price, and built a teleportation channel for nineteen military fortresses to Wangfeng Tower.

Although nineteen teleportation channels have been constructed, it does not mean that the two sides can interact with each other at will, after all, as long as either party puts away the teleportation hanging scroll, the other party will not be able to carry out normal teleportation, and if the military fortress wants to teleport people to Wangfeng Tower, they must also ask the people of Wangfeng Tower for instructions in advance, and after obtaining permission, they will select a specific teleportation time.

This is also Wangfeng Tower's self-protection measures, if there is no restriction on transmission conditions, wouldn't anyone be able to go straight to the exchange?

The payment of millions of points at every turn drove the enthusiasm of the Yitian system, and Zhao Feng received a hidden task initiated by the system after exchanging the nineteenth set of two-way portals-

"Ding!Get the Hidden Mission: Sea City: After system detection, the designated target point is the best city construction address, and the total city construction scale is limited to 100 hectares, with a stable foundation as the standard, when the system determines that the foundation meets the standard, the task will be automatically completed, and the reward is to lift the use restriction of the 'Xuantian Dao Seal'. ”

This is a rare task that can arouse Zhao Feng's motivation, the effect of the Xuantian Dao Seal cannot be ignored at any time, once he obtains the right to use it, Zhao Feng is even confident that he will reverse the overall situation of the end times and bring it back to the right track of the civilized world!

Also on the same day, the survivor forces of the Peace Zone outside the Peace Military Fortress were disbanded, and Tang Yidao, Lao Pantou, and Zhong Yi returned to Wangfeng Tower with twelve other trusted henchmen, just forming a fifteen-person escort team.

The buildings outside the shield of the Lookout Tower are divided and occupied by the City of Hope, the Celestial Circle, and the Holy Maiden Cult, forming an inner area centered on the Lookout Tower, while the outer layer is occupied by small and medium-sized forces, hunter forces, and branches of the military fortress, forming an outer area.

In the next few days, Zhao Feng continued to sort out the materials and design drawings needed to create a maritime city through Xiao Hei, most of the materials could be purchased through the points of the Yi Tian system, and Xiao Hei also gave more than a dozen different design drawings, each of which corresponded to a certain surreal technology, which was the top technology derived by Xiao Hei by combining reality with all the civilization data of the end times.

Zhao Feng finally selected the "Suspended Magnetic Simulation Induction Sea and Air City Project", a technology that uses suspended magnetism as the foundation to stabilize the "Yitiancheng", but the biggest difference between this suspension and normal suspension is its dual core: first, simulated induction, which controls the suspension effect by simulating the magnetic field and magnetization effect; second, the reaction core of simulated induction belongs to perpetual motion energy.

The essence of simulation induction is super technology software, Xiao Hei can complete it directly, and many unknown elements required for the reaction core may not be available even in the pre-civilization world, which involves hundreds of new elements with Xiao Hei's own code name and can even break the existing physical and chemical framework, even if Xiao Hei can carry out simulation experiments without defects through the derivation algorithm, the current technical level of the reaction core is not enough to support the needs of building the core.

However, fortunately, there is the Yitian system.

Zhao Feng directly exchanged ten Yitian No. 5 batteries, divided the reaction core into ten, and changed it to electric energy to drive, replacing part of the formula, and then after Xiao Hei's second calculation, the final result was - feasible!

After solving the technical needs, Zhao Feng bid farewell to the people in Wangfeng Tower and prepared to go to the designated place alone to create Yi Tiancheng......
