"How much time is left for us?" The old man asked slowly.

"Sixty years at most, if we can't leave the range of the sun's helium flash explosion within sixty years, the entire earth civilization will be completely destroyed!" Chief Engineer Zhang said in a trembling voice.

He Xie couldn't help but raise his eyebrows in surprise, it is now 2014, that is to say, the solar helium flash will explode in 2074, at least a few decades earlier than the original plot.

The old man was silent for a long time, his brows furrowed, he tapped lightly on the table and asked again, "Is it safe to escape from the solar system?" ”

"It's not ......," Chief Engineer Zhang shook his head, "In fact, as long as you pass through the Kuiper Belt, you can escape the disaster of the eruption of the sun's helium flash, but in the vast and silent universe, I don't know how many unknown dangers there are...... And, where else can we go? ”

Chief Engineer Zhang wept bitterly: "The closest star system to us is in the constellation Centauri, about 4.2 light-years away from the Earth, and with our current level of spaceflight, it is impossible to get there!" ”

The old man's brows furrowed even tighter: "In other words, we have no hope at all?" ”

"No, not even a little!" Chief Engineer Zhang smiled miserably, "With our current manned spacecraft technology, we can't fly out of the range of helium flash explosions at all, chief, we are doomed!" ”

The old man seemed a little displeased, but he didn't say anything, just rubbed his forehead, nodded to Chief Engineer Zhang, and said, "It's hard to get old, you can rest well." ”

Chief Engineer Zhang left in despair.

The old man's gaze fell on He Xie, and he smiled kindly: "Xiao He, I heard that you proposed this solar monitoring?" ”

He Xie nodded: "Yes, I am sensitive to the changes in the power of the heavens, the earth, the sun and the moon, and I sense that the power of the sun is attenuating greatly, so I want to use scientific and technological means to obtain detailed data to confirm my perception." ”

As soon as these words came out, except for the old man, the leaders present at the meeting all had different expressions.

"This shows that our ancient Chinese martial arts and spells are not without scientific truth!" The old man made a joke, and everyone laughed knowingly.

"What do you think about the discovery of Zhang Lao's team, Xiao He?" The old man asked.

"I agree with the data of Zhang Lao's observation report." "But I don't think we're finished, we still have time, and if the 2.6 billion people are twisted into a rope, they may not have found a way to survive." ”

"Yes......," the old man nodded, "there must be a way." ”

After a pause, the old man asked, "From your professional point of view, is there a way to save the earth?" ”

He Xie shook his head slowly: "In sixty years, I can let a small number of people survive, but what's the point?" ”

The old man was silent, and finally sighed with exhaustion: "What a disaster......

In the end, the meeting came to an end, but the old man hoped that He Xie would stay in Yanjing for the time being to attend the upcoming emergency meeting of the Allied States.

He Xie and Ye Lanqiu immediately stayed at the Diaoyutai Hotel.

"Lan Qiu, contact Xia Dong and Wang Lei and tell them that the progress of student recruitment will be accelerated, and the scale will be expanded from the original 20 million to 100 million." At night, He Xie looked up at the starry sky and didn't look back, "Let Xia Dong fight the application for the expansion of the academy and expand the existing scale tenfold." ”

Ye Lanqiu had already learned everything from He Xie's mouth, and when she heard this, she just nodded silently and walked out of the door with her mobile phone.

A month later, NASA passed the test and came to the same conclusion as the CNSA, and then an emergency meeting of the alliance was held in China.

The seven-day agenda did not come up with any practical solutions, but it did lead to comprehensive cooperation in space science and technology among various countries.

After the meeting, He Xie returned to the City of Hope in Taleqi, at which point his Time Shuttle was only three-fifths full......

All new trainees have been recruited within this month, totaling 98 million people, and the expansion project of the City of Hope is also in full swing.

He Xie spent three days developing two new courses, one was to add the teaching of Fu Seal, which specialized in teaching "Fire Fu" and "Palm Thunder"; The second is to add the teaching of internal strength, a "rejuvenation formula", which has a good effect on pranayama and healing, and can invigorate the blood and soothe the meridians, and the practice can not be afraid of severe cold; The second is called "Cold Ice Formula", which can practice the true qi of cold ice, and has the effect of calming the mind and dispelling fire.

Subsequently, He Xie carried the first generation of students and started a new batch of teaching tasks.

In April, when spring returned to the earth, the Solar Helium Flash Research Group of the Alliance States was established, and the seven heads of state formed full members with the right to vote and make decisions.

On 1 May, the first formal meeting of the Study Group was held in Porta, at which a total of four proposals were adopted.

The first proposal was put forward by the Chinese side, and the aviation bureaus of various countries reached a deep all-weather strategic cooperative relationship to form a good unity situation of data sharing, technology sharing and resource sharing.

The second proposal is the "controlled nuclear fusion project" proposed by the Sara Aviation Authority, hoping to gather the world's top experts in this field to develop a new nuclear-powered engine to prepare for the future escape from the earth.

The third proposal is the "Feasibility Report on the Colonization of Proxima Centauri" proposed by the Lighthouse Space Agency, which can be regarded as providing the first way out for the future of mankind.

In this plan, it is necessary to gather the world's cutting-edge technology to first create a new generation of spacecraft with a new energy source and a new engine, which can carry 10,000 lucky people and millions of human frozen embryos, as well as samples of the earth's ecological civilization, and set off for Proxima Centauri.

In the Lighthouse's plan, the spacecraft would need to be successfully researched within twenty years, and then spend forty years traversing the Kuiper asteroid belt and escaping the range of the solar helium flash explosion.

This bill is very pessimistic, basically just retaining a little spark for human civilization, and the vast majority of people on the earth have actually been abandoned, so it is also called the "last spark plan".

The fourth proposal is the second way out proposed by the China Space Agency, called the "Kuiper Belt Biosphere Feasibility Report".

This proposal is a little more humane than the final Tinder plan, and the difficulty factor is much lower. The idea is to further improve the current level of space science and technology in five years, design a spacecraft capable of flying to the Kuiper Belt, and then gather global forces to build a new type of giant spacecraft every six months, carrying supplies and people, to the Kuiper Belt to build a space station and a self-sufficient space biosphere.

This plan could send at least 50 million people out of the solar system.
