Western Sea City.
A young man in a white sweatshirt stood on the rooftop of the Apocalypse Hotel in the city center.
The young man was tall and handsome. His obsidian-like eyes were clear and gentle.
However, at this moment, his eyes were slightly furrowed as his gaze focused on one point, which was below the rooftop.
This was the tallest building in Western Sea City, the Tianqi Sightseeing Hotel. It had a total of 90 floors and a total height of 445 meters.
This was Yu Bai's fifteenth day here. He had been simulating a falling action, which was to jump from a tall building.
He took out the rubber man tied up by the rope and performed a speed fall test before calculating the data.
"If you land without any protection, your speed will be four meters per second. At the same time, your body will roll because of the loss of gravity, and you will eventually fall. Therefore, the first element of jumping is to ensure the angle of the landing point!”
"What is the success rate of jumping down from a high platform and then jumping into a glass-sized cabin? Two meters was one-fifth, three meters was one-eighth, and four meters was one-twentieth.”
"Therefore, aeromechanics, angleology, and meteorology are all needed. We will perform a latitude test jump at the most suitable height and angle. Then, we will be able to complete this jump by maintaining our balance.”
The diary was filled with records of some kind of crazy professional term.
From jumping from tall buildings to falling, there were also all kinds of predictions to prevent accidents from happening. The professional data records were extremely clear.
"Phew!"
Putting down the pen in his hand, Yu Bai let out a long breath.
To be precise, his calculations were in preparation for the next plane collision.
Yu Bai is a reborn man.
A month ago, during the high school graduation exam, he woke up from a deep sleep in the classroom and looked around in a daze. After being invited out by the teacher, he knew that he had returned to a year ago.
Then, he dropped out of school. For half a month, Yu Bai stayed at home designing data. For the second half of the month, he was preparing for the upcoming event.
On July 1st, 2021, a helicopter carrying a military admiral and a naval nuclear submarine research professor suddenly caught fire. The pilot hit his head and fainted. The helicopter flew in chaos and finally crashed into the rooftop of the tallest hotel in Xihai City. The helicopter crashed and the casualties were tragic.
The detailed reason was estimated by flight experts. After the pilot fainted, no one would control the helicopter that lost control, which led to the crash.
On June 1st, 2020, Yu Bai was reborn. He returned to a year and a month ago.
As a small citizen, he did not report to the higher-ups because this helicopter was extremely important and confidential. Secondly, the process of history could not be reversed, but Yu Bai planned to try to change it!
Reborn and returned, changing the first possibility.
One month of preparation time. The impact force was calculated according to the volume and speed. Then, the impact force and damage degree were calculated. The damage degree of the helicopter was obtained, and then the rescue was carried out.
Even though this seemed crazy, this was the only chance!
The plane that crashed was a Zhi-9 domestic multi-purpose helicopter, mainly used for coastal support, maritime patrol and other functions.
At the same time, the helicopter had been modified into an anti-tank professional military helicopter. It could be seen that the personnel inside were very important.
By learning how to fly a helicopter by himself, Yu Bai could basically simulate a helicopter taking off and landing.
Now, he was just short of this final leap.
"Phew!"
Yu Bai took another breath and looked at his phone.
June 30th, 2020. Tomorrow was July 1st.
"There's still one more day!"
On the 445-meter-high balcony, Yu Bai whispered.
After packing up the equipment, Yu Bai took the elevator downstairs as usual.
First of all, this hotel was open to the public. Some tourists could go to the rooftop to enjoy the scenery overlooking Western Sea City.
He went downstairs to take a taxi. Yu Bai's home was in the outskirts of the city, in the Koi Garden Community.
They arrived at the neighborhood in less than fifteen minutes by taxi. It was a simple two-story building with a courtyard house. Half of the courtyard was planted with peonies and the other half was planted with their own vegetables.
A large black dog was barking softly, welcoming its master's arrival.
"Mom, I'm back."
Yu Bai shouted towards the kitchen.
After dropping out of school for a month and not going out for half a month, Mother Yu thought that Yu Bai had depression and was now making nourishing ingredients all day long.
"Get ready to eat."
The gentle and kind voice made Yu Bai smile.
He washed his hands and prepared to eat.
The dining table was very sumptuous. There were four dishes and one soup, dishes unique to the north.
There was stir-fried meat with chili, pancakes, scrambled eggs, chicken stewed with Chinese caterpillar fungus, and a few cold dishes.
It was healthy, delicious, and fragrant.
The aroma of food filled his nostrils.
After eating a few pieces, Mother Yu took off her apron and looked at Yu Bai.
His eyes were deep, but his brow bones were straight. Just like his father, he was a man who would rather break than bend.
His lips were thin, and with his obsidian-like eyes, he was extremely handsome.
Her own child's appearance alone was enough to beat his peers.
However, when she thought of Yu Bai's recent performance, Mother Yu could not help but sigh.
"Yu Bai, what do you want to do in the future?”Putting down her chopsticks, Mother Yu looked at Yu Bai with bright eyes.
Unknown direction?
Yu Bai was stunned for a moment. In his previous life, he remembered that he had chosen university and witnessed a disaster. Some of his classmates had chosen to join the army, some had died young, and some had chosen to inherit the factory and become small bosses.
"I want to be a soldier, an air force soldier!"
Without hesitation, Yu Bai's voice was calm and firm!
"Follow me!"
Mother Yu stood up, her voice devoid of any emotion.
The central room was the study and also the sacrificial object.
There were two photos in the room. From their eyes, one could tell that the two photos looked very similar to Yu Bai.
Mother Yu pointed at the yellowed old photo. It was Yu Bai's grandfather, Yu Xiong.
"Tell me, how did your grandfather die?”
Mother Yu spoke without any emotion, only a faint sadness.
"In 1975, Beihai died in battle and his body was wrapped in horse leather!”Yu Bai's back was straight like a sword as he spoke calmly.
Mother Yu pointed at the next photo again. It was a military photo of the new era. In it was a middle-aged man in his thirties. The middle-aged man was wearing a sky-blue military uniform and saluting the red flag. However, this photo was also in black and white.
Yu Bai's father, Yu Jianjun.
"How did your father go missing?" Mother Yu's beautiful eyes were filled with sorrow.
"He went to the United Nations for the country and flew over a dense forest in Africa in a military helicopter. The plane crashed and disappeared.”
Yu Bai said in a low voice.
"What about you?"
Mother Yu looked at Yu Bai and spoke again.
"Mom, I have to do something, even if I have to pay a huge price."
Standing quietly, Yu Bai spoke in a decisive and clear voice.
As Yu Bai turned around and left, Mother Yu's eyes were calm, but her smile was bright.
His child was like his father and grandfather from decades ago. He was like a fighter who fought without hesitation.
