A few days later, the day finally came for Tissot to return to Mars.

Xu Shuwei proposed to Chen Mengchuan to hold a speech on Earth first, but Chen Mengchuan refused, and he planned to speed up the time process of returning to Mars. After the other core members saw Chen Mengchuan's statement, they didn't mention this matter.

Subsequently, under the arrangement of Zhao Wanyu, the last group of participants also completed the assembly, and then landed on the Tissot.

After that, Chen Mengchuan said goodbye to Zhao Wanyu and others, set off the Tissot, slowly rose into the sky, activated the space source circle and disappeared above the head of Tianzhi Science and Technology Industrial Park.

Outside a living module at the tail of the fifth floor of Tissot, many people leaned on the handrail of the corridor, communicating in twos and threes, most of them were slightly excited and nervous, and they were informed that Tissot would arrive at the Martian base in three days, and the science summit would be held on Mars at that time.

This time, Tiansuo returned to Mars, not only with nearly 30,000 participants, but also with 3,200 preparatory personnel who had been preparing for more than two months for the metal smelting plant, and these 3,200 preparatory personnel were selected from the 160,000 people recruited at the beginning, and they will become the first batch of staff of the Martian metal smelting plant.

In the next plan, these 3,200 people will participate in the asteroid cutting, asteroid smashing, and metal smelting work of the Mars metal smelting plant, which requires a large number of personnel to cooperate with the multi-armed crab and asteroid capture spacecraft to complete, these work in the earth's Tianzhi Technology headquarters, and in advance for enough time to train, learn and understand.

In addition to the personnel, the Tissot also carried a large amount of material, including a large amount of metal raw materials, food, water, medicine and clothing.

When Tissot first came, the first batch of materials it carried were basically left in the Mars base, because the first batch of scientific research workers also stayed on Mars, so naturally a large number of materials were also left here.

This time, because Zhao Wanyu had done a lot of preparation work in advance, the amount of supplies could be said to be crammed into the entire Tissot cabin area.

Once, when preparing the Tissot, he did not dare to raise supplies too openly, for fear of the suspicion of other powers and countries in China. But this time, after the Tissot was established, the entire earth acquiesced to the existence of the Tissot, and the Huaxia official also hinted at its support, so the amount of materials prepared by Zhao Wanyu this time was simply very amazing!

After Tianzhi Technology spilled countless banknotes, combined with advanced and exaggerated transportation and logistics methods, the effect produced is incomparably amazing. When purchasing many domestic materials in China, they are purchased nearby, and then through the large-scale gravitational working platform with the space crossing, all the same materials are transported to the Tianzhi Science and Technology Industrial Park with amazing efficiency.

An astonishing amount of metals and other experimental materials and experimental facilities, as well as a large number of cattle and sheep, chickens, ducks, geese, poultry, freshwater and saltwater live fish and shrimp, were transported from all over the world in just half a month.

Although there have been many doubts and media criticism in the process, all of them have been perfectly resolved under the negotiation and transaction coordination of Tianzhi Technology's research team.

Therefore, on the Tissot at this time, the space for these experts, scholars and the preparatory staff of the metal smelter to move is much smaller, but Chen Mengchuan still opened a lot of activity areas and leisure areas for these people, and even opened the fruit and vegetable area to everyone.

The direct effect of reducing the activity area and increasing the number of people is that the Tissot is much more active, and you can see people everywhere, or several, or in groups, and the communication with each other is also very enthusiastic, and you can often see arguing and debating because of different opinions and opinions.

This kind of atmosphere makes everyone feel very beautiful and harmonious, because this is the collision of a large number of high-level intellectuals in academic disciplines, and the atmosphere brought out by this large number of collisions makes everyone intoxicated.

After more than 60 hours of sailing, Tissot arrived on Mars again.

When this beautiful crimson planet appeared in front of the Tissot passengers through screens, everyone held their breath, and the incomparable beauty made everyone shudder.

Under the technology of Tianzhi Technology, human beings have descended on Mars for the second time.

Except for the original Tissot crew, everyone else has imagined the appearance of Mars countless times in their minds, and has seen it through many photos, but when Mars really appeared in front of this group of experts, scholars and scientists, everyone was completely shocked by this scene, unable to say a word, there was silence everywhere, and the previous conversations, disputes, and debates were all banned.

Everyone looked greedily at this beautiful but incomparably barren planet.

[Ladies and gentlemen, we will arrive on Mars in 30 minutes and land on the Martian base of the "Falling Feather" crater, Liuyan Palace, which is located on the equatorial ...... of Mars]

[We are coming to the end of this trip, ladies and gentlemen, please return to their respective cabins......]

Inside the Tissot, the radio sounded.

As the radio sounded, everyone seemed to wake up, and everyone began to be excited in disbelief, and in an instant the entire Tissot was full of conversations and discussions, and all the focus was only one, that is, Mars, the beautiful planet that haunted mankind's soul.

The main control center of the Tissot spacecraft, Chen Mengchuan and others are also understanding and continuing to take over the work on Mars in an orderly manner.

During the period of parting, the progress of the work on Mars is basically still relatively complex with everyone's estimates, the overall completion of the infrastructure work is very good, and the completion of exploration is also excellent, basically the surface of Mars has been completely scanned, and the 3D body surface structure map of the entire Mars has been imaged in the database of Tissot artificial intelligence Yue'er.

Mars, like Earth, has a very diverse terrain, with mountains, plains, canyons, and so on.

The terrain of the northern and southern hemispheres of the planet is a stark contrast. The northern hemisphere of Mars is a lava-filled lowland, and the southern hemisphere is an ancient highland full of impact craters, and there are clear slopes between the two, interspersed with a large number of volcanic terrain, and countless canyons of various shapes, deep and winding. At the North and South Poles, there is a polar crown of water ice and dry ice, which is similar to the Earth, and wind-formed sand dunes spread almost the entire planet. With the increasing data collection of Tianzhi exploratory polycybby crabs, more and more intriguing topographic landscapes have been discovered.
