Angel said: "Our second step is to thicken the atmosphere of Mars and maintain the temperature on the surface of Mars. At the same time, adjust the gas composition in the atmosphere, remove those toxic gases, increase the oxygen and nitrogen content ratio to meet the requirements of our human life. We will start artificially creating the Martian ozone layer, using this ozone layer to block the exposure of ultraviolet rays in the sunlight to Mars."

"After the large energy-concentrating array starts to operate, the Mars base will not lack energy at all, so we will use a large amount of electricity to electrolyze water. By extracting the water from the primitive ocean of Mars and electrolyzing it, we can produce enough oxygen and hydrogen. We store the hydrogen as future energy, and oxygen is directly discharged into the air to increase the oxygen content in the atmosphere. At the same time, we will create a large amount of nitrogen and discharge them into the air. In addition, we will also emit specific gases into the atmosphere, which will react chemically with the highly toxic gases in the air to decompose these highly toxic gases, thereby reducing the content of these highly toxic gases in the atmosphere and allowing the Martian atmosphere to slowly change in the direction we designed."

"Under the influence of our special mixed gases, the temperature on the Mars surface will gradually rise within half a year. After the temperature on the Mars surface rises to more than zero degrees, the ice under the permafrost layer of Mars will melt in large quantities. Under the action of Mars' gravity, these liquid water will be squeezed out of the ground and become seawater in the primitive sea of ​​Mars. Once the primitive sea is formed, a large amount of water vapor will be generated in the air. These water vapor can further thicken the thickness of the atmosphere and make the temperature of Mars continue to rise."

"Then we will sow a large number of algae plants in these primitive oceans. These algae plants can absorb a large amount of carbon dioxide in the air and then convert them into oxygen. On the Martian surface, we will plant some sand-fixing fungi and bryophytes on the Martian soil. These plants can not only prevent sandstorms and reduce the carbon dioxide content, but also produce more oxygen, slowly turning the Martian surface into a truly nutrient-rich soil and expanding the range of our human activities."

After listening to An Qi's explanation, Liu Hui had a question in his mind and asked: "At the beginning, the environment on Mars was so harsh. Those algae, fungi and bryophytes should not be able to survive, right?"

Angel smiled and said, "It is true. At the beginning, those algae plants will slowly die due to the harsh Martian environment. But a new invention was created in our genetic research room, which is to stimulate the vitality of plants in a short time, and then these plants will die quickly after they grow and mature. We have applied this technology to algae, fungi and bryophytes. We sow the plants after genetic modification. Although most plants will die in a short time, they still
