"Is this necessary, old fellow?" When Lin Feng left, Yang Yi asked.

"What do you kid know?"

"You ......"

Yang Yi just spoke, but before he could react, his wrist was grabbed by Yang Chengzhi.

"What are you doing, old fellow?"

"Nice, nice, nice!" With a smile, Yang Chengzhi let go of his hand.

"What's good?"

"What, still pretending to be with me?" Yang Chengzhi looked at Yang Yi and said with a smile, "Now, believe the story I told, right?" ”

Yang Yi was slightly stunned, and his brows immediately locked together.

"If you want to know more, just follow me."

Seeing Yang Chengzhi get up, Yang Yi hesitated for a moment, then got up and followed.

After a while, the two came to the basement.

"Old fellow, what are you bringing me here for?"

"Less nonsense."

Yang Chengzhi walked to the corner and tinkered with the wall, and the floor in the center of the basement was moved to both sides, revealing a deep underground passage.

Yang Yi was very surprised, because he had lived here for eighteen years and had never known about the existence of this tunnel.

"I know, you kid can't hide things in your heart, since you brought her to see me, you must have told her everything that should be said and what should not be said." Yang Chengzhi walked over, looked Yang Yi up and down, and then said, "Just say it, but you have to keep your mouth shut in the future." ”

"Old Fellow......"

"Let's go."

Yang Chengzhi took the lead in drilling into the tunnel, Yang Yi was full of doubts in his heart, but he was also very curious, and followed into the tunnel.

After walking dozens of meters, the two came to a spiral stairway. After descending for another hundred meters, there was a faint light ahead. Although he couldn't see his five fingers in the tunnel, Yang Yi was a soldier and could see clearly. To Yang Yi's surprise, his grandfather could also see clearly.

The light comes from an oil lamp and is a naturally formed cave.

The cave is very large, and there are some household items in a mess, and there is a stone table and two stone benches in the middle of the open space, and oil lamps are placed on the stone table.

"This ......"

"Yang Yi, you have grown up, and you have found the 'Hope' and accepted the transformation, so you should know these things."

Yang Chengzhi's tone suddenly became serious, which made Yang Yi not very accustomed to it.

"Sit down."

Yang Chengzhi sat down first, and Yang Yi walked over and made it to the stone bench opposite.

"I know you have a lot of questions on your mind. What you have seen and heard in the past six months, and what you have experienced, may have turned your worldview upside down. ”

Yang Yi didn't say anything, but Yang Chengzhi didn't say anything wrong.

"Now, let's start from the beginning."

Yang Chengzhi raised his hand, and when Yang Yi noticed the abnormality, a ray of light shot out from Yang Chengzhi's fingertips and stabbed Yang Yi's forehead.

"Grandpa......"

"Don't resist, sleep in peace."

Yang Yi's eyes widened, and a strong sense of exhaustion popped into his mind, although Yang Yi didn't want to close his eyes, but quickly gave up resistance.

It was an irresistible force, but without the slightest malice.

After waking up suddenly, Yang Yi was surprised to find that he was standing behind a huge floor-to-ceiling window, and outside the window was a strangely shaped spaceship, and Yang Chengzhi was standing behind him. Subsequently, Yang Yi calmly realized that he was a five-year-old child!

Behind him, Yang Chengzhi is not the one Yang Yi is familiar with, he looks younger.

"Report to the tower, Discovery is ready for launch."

"The tower receives it, starts the launch procedure, and the sixty-second countdown begins. Fifty-nine, fifty-eight......"

As the countdown ended, the spaceship outside the window ignited. The place where Yang Yi is located is the tower, and behind him is the command and control area.

"The main engine ignites and accelerates."

"Everything is working well with the systems, and the space curvature propulsion device is activated."

"The space curvature propulsion device is ignited, and the propulsion power is ten percent."

"According to the tower, the propulsion power has reached 80 percent."

"Have a nice trip to the Discovery."

……

The spaceship was far away and extremely blurry. After a flash of light, it disappeared from Yang Yi's field of vision. Yang Yi also saw that the spacecraft did not make a space jump, but used a more direct means, that is, to accelerate by distorting space. The spaceship did not disappear, but reached the speed of light.

A spaceship that flies at the speed of light!

It's just that Yang Yi knows that it is not the "Hope", but a larger spaceship than the "Hope", and there are two people on the spacecraft, a man and a woman.

It was at this moment that a blinding light flashed.

When the light disappeared, Yang Yi found himself in the vast sea of stars, full of stars in all directions, and Yang Chengzhi stood in front of him.

"Grandpa......"

"That's the one thing you remember the most before you were five years old. You were three years old, to be exact. ”

Yang Yi was slightly stunned, looked at Yang Chengzhi in disbelief, and realized at the same time that this was his hallucination, or in his consciousness space.

"Come to think of it, do you still have memories of things before you were five years old?"

"This ......"

"Yes, but it's all vague. Quite simply, I imprisoned your memories because they only cause you great pain. ”

"Why...... It's ......"

"It was your own parents who left on that spaceship." Exploration' was the second ship I designed and built capable of traveling at the speed of light, and the first manned spacecraft. Not the only option, but in order to travel to the future, your parents volunteer to be the first astronauts to travel at the speed of light. Yang Chengzhi let out a long breath and said, "They are also my son and my daughter-in-law. ”

"Grandpa......"

"If it weren't for this, we wouldn't be here." Yang Chengzhi smiled indifferently and said, "Theoretically, when the spaceship flies at the speed of light, the internal time will stop, so you can travel to the future with a spaceship traveling at the speed of light." It was only shortly thereafter that I discovered a problem. ”

"What's the problem?"

"Flying at the speed of light can bring time to a standstill, but after slowing down, time doesn't return to normal."

Yang Yi was slightly stunned, and looked at Yang Chengzhi incomprehensibly.

"To put it simply, even if the control equipment on the Exploration is functioning normally and slows down in reverse acceleration after reaching its destination, the time inside the Exploration will not return to normal. As a result, astronauts on Discovery's space trips are unable to wake up from their slumber and will remain unconscious even after reaching their destination. Although they are still alive, they are no different from death. ”

"This ......"

"It was this discovery that made me realize that eliminating space constraints by increasing speed simply wouldn't work. It's just that I don't care more about these, but about them. ”

"And then?"

"Over the next two years, I used up all my savings, found a way to bring time back to normal, and built a third spaceship capable of traveling at the speed of light."

Yang Yi was taken aback and said, "You take me and take this spaceship for a space trip?" ”

"That's right."

"But ......"

"Although I am your grandfather, every child has a parent. Don't ask me why, don't blame them, blame me. ”

Yang Yi was dumbfounded, and suddenly thought of something.

"Looks like you've thought of it."

"You...... You are ......"

"That's right, I am Yang Feng, the protagonist of that story, the ancestor of the Yang family."

"No, it can't be. You're Yang Feng, then I'm ......"

"You are my grandson, Yang Yi."

Yang Yi patted his head a few times, trying to wake himself up, because he felt that it was a dream. If so, he is from 10,000 years ago.

Is this possible!?

"I can travel to the future, but I can't predict it. After coming to this world, I realized that the reality is more cruel than I imagined. ”

"So you're imprisoning my memories before I was five years old?"

Yang Chengzhi, or Yang Feng, nodded, and said: "Although it is very unfair to you to do this, in order for you to survive in this strange world, in order for you to be able to meet your long-lost parents, I have no choice." Like I said at the beginning, if you want to blame me, just blame me. ”

"So, why tell me?"

"Because you found the Hope, there is hope for the future."

"What?"

Yang Feng took a long breath and said, "'Hope' is the first spaceship I have built that can fly at the speed of light, and it is also the only unmanned spaceship. What's more, Hope has hosted discoveries that will change the entire human civilization and even the galaxy. It's been 10,000 years and the chance of finding Hope is almost zero, but your discovery on Lava has changed all that. ”

"This ...... What the hell is going on? Yang Yi was confused, or at a loss.

"It's a long story."

"Don't tell me, it's a dream."

Yang Feng smiled miserably and said, "This is not a dream, but a communication of consciousness, which looks like a dream." ”

At this time, it is no longer possible to use words to describe Yang Yi's mood.

"If you're wondering what's going on, answer my question first. Do you believe in history? ”

Hearing this, Yang Yi was taken aback, because not long ago, Zhan Ruilin asked the same question, and then the things he told completely changed Yang Yi's worldview.

Immediately, Yang Yi thought that Zhan Ruilin had told him that he had a relationship with his grandfather, that is, Yang Feng.

Could it be that Zhan Ruilin was also influenced by Yang Feng?

If all this is true, and the grandfather who has accompanied Yang Yi for eighteen years turned out to be Yang Feng, the ancestor of the Yang family, and he is an orphan from 10,000 years ago, then the past of human civilization is definitely different from the history that Yang Yi understands, and Yang Feng must have a very important reason for coming to this era.

The more he thought about it, the more confused Yang Yi's thinking became.

Not to mention whether he believes all this for the time being, just thinking about these makes Yang Yi feel incomprehensible and completely unreasonable, like he is having a nightmare.
