Zhang Kai took two steps forward, stretched out his hands to hold Xia Tian's shoulders tightly, his lips trembled for a long time before saying a word: "Okay!"

Next, Xia Tian gave detailed explanations to the two base commanders one by one. After that, a new awakening movement began vigorously.

Xia Tian entered the secret realm again. As soon as the next batch of 110 new warriors selected by lottery crossed the gate of the secret realm, they immediately drank the awakening potion prepared by Xia Tian for them.

According to past experience, the time it takes to wake up the green road after taking medicine is about an hour, and summer will not waste this time waiting in vain.

He turned around and returned to Kunlun base again, and had a new round of communication with the two base commanders.

The potion in Xia Tian’s hand can give birth to more than 2,000 psychics, which is undoubtedly the largest force in the secret realm.

However, there are still two problems in how to organize so many people.

That is the traffic issues and communication issues. The secret realm has been expanding again and again, and even in summer, it has not fully explored the entire edge of the secret realm.

According to his speculation, the secret realm today is likely to span thousands of kilometers, even at the relatively close location of the Saxon Federation Secret Realm Gate, it is seven or eight hundred kilometers away from the entrance to the secret realm of Kunlun Base.

There are many more than two thousand superpowers, but they are actually very difficult to control such a vast area.

The terrain of the secret realm is mainly mountain plateau, with mountains crisscrossing and roads difficult to walk.

Although these two thousand people are all superpowers with excellent physical fitness, just rushing between different strongholds will probably consume all the source energy in their bodies.

In addition, Kunlun base has built a watchtower and twelve small black houses, and hundreds of people are needed to guard each base. Therefore, communication between the bases and food supply for the garrison soldiers is also a big problem.

Xiatian, Zhang Kai, Murong Xue, and other base managers simply held a roundtable meeting at the entrance of the secret realm. Everyone worked together to discuss the questions raised by Xiatian.

This meeting lasted for more than ten hours. Every hour after that, I entered a secret realm in summer, raising awakening for the new group of soldiers who entered.

Then he hurried back to the base again. After repeating this process more than ten times, all the ordinary soldiers existing in Kunlun base were awakened!

Kunlun Base has become a garrison of all abilities with nearly 3,000 members!

While discussing with the base managers, Xia Tian nervously deduced various plans in his mind and the system. While waiting for the last group of soldiers to awaken, he finally came up with a suggestion.

Considering the characteristics of mountainous land in the secret realm, the best way to travel is undoubtedly air transport. The final solution proposed in summer is: to build a large number of airships!

Airships are a type of airplane, and are also aircraft that use gases that are lighter than air to provide lift.

According to the working principle, aerial vehicles can be divided into airships, tethered balloons and hot air balloons, among which airships and tethered balloons are the most useful aerial vehicles.

The main difference between airships and tethered balloons is that the former has more power systems than the latter, which can fly by itself. Airships are divided into two categories: people and unmanned, and there are also differences between tethered and untethered.

The lift obtained by airships mainly comes from the inside of it that is lighter than air, such as hydrogen, helium, etc. Generally, airships use helium with better safety to provide lift.

As a self-sufficiency frontier position on the earth, the Kunlun base has a large amount of combat preparations, and it is not a big problem to build several airships.

There is no ready-made hydrogen and helium in the base, but fortunately, this is a world of superpowers, and there are not many things that superpowers cannot solve!

The plan proposed by Xia Tian was immediately approved, and a large number of personnel and materials were mobilized in a tight and orderly manner.

With such a huge size as the airship, it is impossible to pass the secret realm gate at all, so building the airship must be carried out within the secret realm.

At this time, he was naturally the omnipotent Xiatian designer, engineer and technician who took the initiative personally.

Hundreds of soldiers who had just completed their awakening excitedly helped Xia Tian move various materials into the secret realm, and then under Xia Tian's command, they began to build such a huge aircraft on the spot.

Airbags, auxiliary airbags, pods, propulsion devices, tail wings, and all the main components of airships are gradually formed in summer.

A few hours later, the super giant airship with a length of 237 meters, a maximum diameter of 30.5 meters, and can be filled with 104,700 cubic meters of floating air body. Its weight is 118 tons and a load of 53 tons is finally born!

As Xiaobai used the wind-type superpower and injected light gases treated with superpower into the airbag, the blue-green airship completed the last step before it took off.

Previously, Xia Tian had recalled many warriors including Liu Fei through Xiaobai who mastered wind powers, and Liu Fei will become the first pilot of this airship.

Hundreds of soldiers lined up in neat rows and entered the cockpit under the airship. Liu Fei looked at the indescribable sky fortress and gently shook Xia Tian's arms.

There was a light flashing in her eyes and she said, "Captain, this is an airship you built with your own hands. Give it a name!"

For some reason, the faces of two sisters suddenly appeared in Xia Tian's mind, and he said slowly: "This airship, just call it [Little Love]."

Then, he patted Liu Fei's little head: "Go, go for your first flight!"

Liu Fei originally planned to ask Xiao Ai who she was, but then she swallowed her words and just spit out a word: "Yes!"

She quickly ran into the front of the cockpit. After the pilot sat down in the cockpit, she held the source energy crystal in her hand and instilled wind-type superpowers into the airship's power system.

Then, she signaled to the auxiliary soldiers beside her to complete the preparation work, and a small blue flag stretched out from the window of the airship cockpit to keep waving.

Xia Tian nodded and waved his right hand hard, and the two soldiers immediately untied the fixed rope of the airship.

Under the huge buoyancy, the [Little Love] sky fortress quickly took off.

After flying to a height of 500 meters, the rear power system of the cockpit sprayed a blue tail flame, and the huge airship turned around in the direction of the Saxon black room.

At the window entrance of the airship cockpit, dozens of soldiers put the source energy crystal iron rifles in their hands on the window frame, pointing their dark muzzles diagonally at the wind.

Five hundred meters is exactly the best shooting distance for the source energy crystal iron rifle. This airship is not only a means of transportation, but also an air armed fortress with patrol and attack functions!

Watching the soldiers who flew to the depths of the secret realm at high speed and assisted Xia Tian to build spaceships, they couldn't help but throw away their hats, hugged and cheered.

Everyone knows the strategic significance of airships, which can carry loads, save the source energy consumption of marching, and also greatly improves the safety factor of the soldiers when flying in the air.

After the cheers stopped for a while, Xia Tian smiled at the corner of his mouth and said to the soldiers: "Comrades, friends, an airship is not enough!"

"Let's work harder and create [Xiaoqi], [Xiaoyi], and [Xiaobai] as soon as possible!"
Chapter completed!
