The next day, Zhao Huasheng met the girl he had seen yesterday again. It was the morning, and the sky was densely packed, with star-like sunlight reflectors surrounding the slightly dim sun, which together with the sun brought warm air to the city of life and allowed the various plants in the city of life to grow. Zhao Huasheng sat on a stone bench in a small park, with his hands on the back of his head, leaning on the back of the chair, raising his head and quietly looking at the sky, not knowing what he was thinking.

At this time, a soft female voice came into Zhao Huasheng's ears: "Hello, can I sit here?" ”

Zhao Huasheng withdrew his gaze to the sky, looked ahead, and saw the girl he accidentally bumped into yesterday standing in front of him. The difference is that she has changed her outfit today, from professional clothes to casual clothes, but the quiet and tranquil atmosphere on her body has not changed.

Zhao Huasheng didn't show too much attention to her, just moved to the side, and then said, "Yes." ”

Seeing Zhao Huasheng lower his head, the girl said with a little surprise: "Ah, what a coincidence, it turned out to be you." Didn't you go to work today either? ”

Zhao Huasheng looked at the sky again, and said lightly: "I don't have a job. ”

"No job?" The girl seemed a little confused, but didn't ask much. After sitting down beside Zhao Huasheng, a good smell, like a light fragrance of flowers, came into Zhao Huasheng's nose. This made Zhao Huasheng's brows furrow again.

"I was sick today, I didn't go to work, it was too boring to be bored at home, so I went out for a walk, I didn't expect to meet you again, what a coincidence."

"Hmm."

"My name is Wang You, what's your name?"

"Hmm."

"Where do you live? You seem to be very heavy, do you have something on your mind? ”

"Hmm."

"Oh, can you tell me what's on your mind?"

"Hmm."

No matter what the girl said, Zhao Huasheng always replied with a faint word. seemed to notice that Zhao Huasheng didn't want to speak, so the girl also quieted down, sat next to Zhao Huasheng, spread the book in her hand on her legs, and read it quietly.

This scene was also captured by a stealthy camera and then transmitted to a distance.

Zhao Huasheng did not leave here, but chose to still sit here. I suggest that the contact index of No. 2 be raised to 80 points, with a level of advanced, and that planning for the third contact start as soon as possible. ”

…………

Time passed quietly, about an hour or two later, the girl closed the book in her hand, then stood up, and said to Zhao Huasheng: "It's not early, I'm going back, aren't you going home?" ”

"Hmm."

"That'...... Good bye. Thank you for spending this morning with me. ”

"Hmm."

Zhao Huasheng still put his hands on the back of his head and looked up at the sky, never looking at the girl. The girl waved her hand at Zhao Huasheng, and then turned to leave.

Time is still passing peacefully. This area of the City of Life is like a paradise on Earth, and no matter how much the outside world changes, it cannot spread. Zhao Huasheng's life is unprecedentedly leisurely and unprecedentedly comfortable.

This kind of leisure and comfort is not only reflected in the state of life. No matter where Zhao Huasheng went, Zhao Huasheng could always sense a faint warmth enveloping him. Whether it was a smiling grandmother he met by chance, or a child who was jumping around with a lollipop in his hand, or a young person of the opposite sex who was very beautiful and very kind to him, or a group of energetic young people he met by chance at a picnic - in that chance encounter, Zhao Huasheng was just passing by, and was pulled into the party by a group of young people sitting on the floor, watching them sing, tell stories, drink beer until they got drunk, and laughed...... Although Zhao Huasheng had been watching quietly from the sidelines and did not participate, Zhao Huasheng could also experience their relaxation and their joy.

Life goes on like this. Zhao Huasheng is like a ghost walking in the world, watching all the beauty of this world with cold eyes, and then not contaminated with any dust in this world.

There are so many people of all kinds who appear in Zhao Huasheng's life circle that Zhao Huasheng has counted, but none of these people have caused ripples in Zhao Huasheng's heart.

Zhao Huasheng has also been following the progress of the comet impact plan. In order to stabilize people's minds and promote self-confidence and cohesion, the human government has been announcing the details of the progress of the comet impact plan. Whether it is from the Internet or traditional media, Zhao Huasheng can obtain sufficient information.

Scientists first mobilized a huge number of observation forces, pointed countless telescopes at this comet that had not been taken seriously before, and even launched three probes to observe next to Comet Arthur, one of which also attached a lander to land directly on the largest piece of Comet Arthur's largest debris.

Scientists numbered the fifteen large pieces alphabetically, naming them Arthur A, Arthur B, and all the way up to Arthur O. The scientists determined in detail the size, mass, shape, gas content, elemental composition and other physical properties of the fifteen fragments, and then made precise and detailed calculations on the orbit of Comet Arthur, gas ejection rate and other data.

Once the data is obtained, the scientists move on to the next step of the calculations. Scientists divided the sun's surface into fifteen different sizes and began to figure out which piece of debris would be the most appropriate to hit which area. After the results of this step of inference and calculation, the scientists began to simulate the forward trajectory of the comet fragments, and began to calculate how much engine thrust and how much gas ejection rate should be used to make the fragments move according to the calculated orbit.

This is a very large and sophisticated computational process, and this is the first time in human history that such a scale has ever been made. But there is no choice in the human category, after all, this is the least expensive and most successful method in the calculation, so human society must go all out to do this thing well.

Tens of thousands of scientists are involved in modelling and calculations, as well as in mission planning, as well as the construction of the Skylab space base.

As the scientist put it, it would not be cost-effective to launch the solar reflector and engine directly onto Comet Arthur with a conventional rocket with high thrust and a one-time use. Building a space base in orbit around the Earth as a transit is the most time-saving and labor-saving approach. The transportation of supplies between Skylab and the ground is handled by a new reusable rocket, and because Skylab itself orbits the Earth at extremely high speeds, it doesn't require much propulsion and too much fuel to launch a rocket from it.

The entire human civilization has devoted itself to the preparation of the Skylab with great efficiency and enthusiasm. Skylab is based on the Lighthouse space station, which previously existed in orbit around the Earth, and was modified from a large number of subsequent deliveries of supplies and equipment. Because it was not built entirely but was modified and expanded, the construction of Skylab was extremely fast, and it took only two months to complete.

There are two main reasons why such a huge construction project was completed in such a short and unbelievable period of time: first, human science and technology have developed greatly compared to before, and second, human civilization has invested the most resources in this matter.

After completion, the total length of the Skylab has reached 463 meters, the width has reached more than 200 meters, and the thickness has reached more than 30 meters, which is larger than the largest aircraft carrier on the earth. It consists mainly of three living quarters, as well as a space rocket launcher, and a large storage warehouse. Fifty-seven highly trained astronauts and engineers are stationed at the Skylab, under the command and assistance of ground staff and with the help of numerous automated equipment, to perform the day-to-day maintenance of the laboratory and the daily launch missions.

After the completion of Skylab, more and more intensive rocket launch missions were launched, and huge quantities of materials and equipment were transported to Skylab. A new spaceship was assembled and given the name "Lightbringer".

The spacecraft will be launched directly from Skylab, and then it will dock with Comet Arthur after a five-day space journey, at which time, under the remote control of its own program and ground control base personnel, solar reflectors will be installed on top of the fifteen large fragments of Comet Arthur, allowing the fragments to move forward according to the will of human civilization.

Spacecraft launches in a space environment have a very different launch mechanism than they do on the ground. The ship launched here does not need a large rocket as a carrier, and here, the rocket is reduced to a relatively small detachable thruster that will contribute enough propulsion to the Lightbringer spacecraft to break free from Earth's gravity and accelerate to extremely high speeds, and after completing its mission, it will automatically disengage from the ship in order to reduce the total mass of the ship. After that, the fuel stored on the Lightbringer will continue to accelerate it until it has the same speed as Comet Arthur and is relatively stationary.

Two and a half months later, Comet Arthur is still 11 million kilometers away from Earth. It was at this time that the Lightbringer unmanned spacecraft, loaded with the supplies needed for this mission, left Skylab, and stepped into the vast space under the gaze of all humans.
