As time passes, this "green star ecology" that has become an alien star begins to continue to show its powerful influence.

Although forests, as one of the most important ecosystems on the earth, play an irreplaceable role in the survival and development of human beings. They can not only provide fresh air, regulate climate, maintain water and soil, but also provide habitat for organisms, historical records show that excessive increase in forest area has also led to huge disasters.

306 million years ago, in the late Carboniferous period on Earth, due to frequent plate movements and high temperatures, the photosynthesis of plants was promoted, resulting in the vegetation coverage further increasing to about 95%. Although this excessive vegetation coverage and oxygen concentration of up to 45% provided abundant oxygen to organisms at that time, it also led to an oxygen poisoning crisis. Excessive oxygen concentration made the insects huge, and even more terrifying that in the extremely rich oxygen, a little Mars would cause a downpour.

During that period, the drifting continental plates had not yet split but were connected together. Neither animals nor plants could escape the fire, causing the extinction of biological organisms. The fire continued to burn, and the 95% forest coverage rate made it impossible for the fire to be extinguished. It is said that this world-destroying fire lasted for 30 years, burying most of the species on the earth in the sea of ​​fire. A small number of creatures left the land where they had lived for countless years and entered the ocean to recuperate.

After this fire, the oxygen content dropped sharply, becoming one-third of the previous fire. Ashes were everywhere on the land, which helped the plant regeneration later. But at the same time, it also caused the earth to continue to cool down, and then ushered in the early Little Ice Age, and a large number of animals and plants became extinct due to the inability to adapt to the drastic changes in the environment.

However, the green star in the post-biochemical doomsday era in front of us is completely different from the earth in the late Carboniferous period. These living "corpse trees" have strong fire resistance and cannot even be ignited.

In fact, the "fireproof trees" in nature mainly include wood lotus trees, sea pine trees, camphor trees, etc. Due to their special physical and chemical characteristics, these trees can play an important role in fire prevention and fire extinguishing in fires.

Wood Lotus tree is an excellent fire-resistant tree species. Its leaves have high moisture content and hard wood, and has a good flame retardant effect. The leaves of Wood Lotus tree have a moisture content of up to 42%, making it able to remain calcined in the flames without burning. In addition, the tree canopy of the wood Lotus tree is tall and its branches and leaves are lush, which can form a solid firewall to effectively block the spread of the fire.

Sea pine trees are also a tree that is not afraid of fire. The wood is hard and has strong heat dissipation ability, and can be kept intact during fires. The leaves of sea pine trees are burned at most in fires, but new leaves can still grow and bear fruit in the next year. The fire resistance of this tree is mainly due to its strong wood and excellent heat dissipation ability.

Zhangke is a tree that can actively extinguish fires. When a fire occurs in a forest, Zhangkeke can spew out juice containing fire-extinguishing substances (carbon tetrachloride), effectively reducing the fire and even extinguishing the flames. This characteristic makes Zhangkeke play the role of a "natural firefighter" in nature.

The special physical and chemical characteristics of these "fireproof trees" are all reflected in the structure of the "corpse tree" in similar but completely different.

In other words, no matter whether it is artificial arson or lightning strike, these zombie forests cannot be ignited.

What's even more terrifying is that they have sucked away the water resources on the earth. Even the water vapor content in the atmosphere has almost dropped to a minimum. Water shortage has become the number one survival problem. This may be the reason why the mutated green star has not yet been able to give birth to a new ecology. Without water, organisms cannot survive and reproduce.

Of course, from the perspective of the shelter, this must be because the plot is frozen. Wu Chen's arrival is releasing the plot, allowing the main line to continue to be derived. With the subtle changes (plot conflict) are happening as the main line of the exclusive branch of 0326 is subtle.

The above is the scientific results of the simulation calculation of the on-board computer "Fortress-279" supported by the "Super Brain Regional Chain". The only possibility that the "Green Star Ecology" is similar to the Earth ecology in the late Carboniferous period is that excessive oxygen concentration will lead to the enlargement of the insects.

If there are insects.

This is also what Wu Chen is most worried about. So he strives to build the Oasis Sky Island as a war fortress. The world's tallest building, Dubai Tower, is an isolation area to resist the upcoming mutant insect tide, and it is also a buffer zone to receive survivors. Once the battle is unfavorable, as long as the survivors are sent to the Oasis Sky Island with a high-speed elevator, Wu Chen will immediately unansalvage and fly into the stratosphere.

Or someone may ask, directly use the aircrew girl's transformed shuttle "Flame Shark" to send survivors directly to the sky island. Isn't this more time-saving?

Think about it, why Wu Chen only lets the survivors of the last time and space flight survivors eat "airplane meal". Before the survivors of the post-biochemical doomsday era are completely determined whether they are "clean", Wu Chen will never let him infect more people. This Dubai Tower, which was cleaned up by a drone and restored all functions and was moderately transformed, is the best "biochemical isolation area". Only when it is determined that there is no risk of "cleanness" will Wu Chen transfer the survivors to the isolation cabin on the Oasis Sky Island for further verification.

The same sentence is the same. The intuition solidified by experience allows Wu Chen to handle such a starting style as the plot is easy to enter the scene.

"Sir, we found a strange piece of 'alpitation areata'." Valkyrie "Valkyrie" Megan Gale popped up the latest satellite map data.

"It looks like a nuclear submarine." Wu Chen enlarged the satellite image: "And it is a Typhoon-class ballistic missile nuclear submarine of the former Soviet Union."

The Type 941 strategic nuclear submarine is the largest ballistic missile nuclear submarine of the former Soviet Navy and the world's largest submarine record as of 2017. It was later replaced by the Russian God of North Wind. The typhoon-class nuclear submarine with a length of 171.5 meters, 23.3 meters wide, and a displacement of 46,000 tons can carry up to 200 warheads. It can destroy 200 targets with a fatal firepower, which greatly reduces the effective interception capability of the enemy's air defense system. It is for this reason that there are rumors that only one Typhoon-class nuclear submarine can destroy a country, which is a typical Cold War product.

"What did you think of?" asked Valkyrie "Valkyrie" Megan Gale with a smile.

"The Typhoon-class nuclear submarine made a stunning appearance in "Resident Evil 5: Punishment". There are many submarines parked inside the undersea experimental field, one of which is the Typhoon-class. It was transformed by the Umbrella Company into a global transport tool for transporting biochemical weapons. In the final decisive battle, the umbrella pursuers also took a Typhoon-nuclear submarine to break the ice and floated on the typhoon nuclear submarine." Wu Chen's plot memory is likely to be wrong.

"So this typhoon nuclear submarine that was 'solidified' in salt crystals may have the survivor we are looking for." Valkyrie "Valkyrie" Megan Gale also thought so.

"Specific coordinates." Wu Chen acted immediately. This was obviously an "first contact" derived from the plot and promoted the main line. In the jargon of the player, "the first electric shock" was said.

"The original Red Sea is located at the deepest part of the Savagin Trough near the Gulf of Suez." Valkyrie "Valkyrie" Megan Gale quickly determined the exact coordinates.

The Red Sea is located between northeastern Africa and the Arabian Peninsula, with an average depth of 558 meters and a maximum depth of 2514 meters. It is narrow and long. It is connected to the Mediterranean Sea through the Suez Canal in the northwest, and to the Gulf of Aden through the Mande Strait in the south. It contains about 4.1% salt, which is the sea with the highest salinity and is also an important oil transportation channel in the world.
