Start with a planet hitting the earth

Time passed by little by little.

The universe created by Chen Yuan and Ya once again expanded, and the celestial bodies gradually disappeared.

After the expansion ended, the power of technology was used to rebuild the universe.

Chen Yuan and Ya have been accompanying each other and continuing to live.

It is unknown how long it has been.

"What is happiness?" Chen Yuan was thinking about this question.

When Ya heard it, she looked at Chen Yuan and said, "Are you talking about dopamine?"

"The human brain secretes dopamine, and dopamine can stimulate the human body and make people feel excited and happy."

Ya looked at Chen Yuan and said with a smile, "This is the essence of happiness."

Hearing this, Chen Yuan looked at Ya and said, "Then are you happy?"

Ya looked at Chen Yuan and smiled, "As long as I am by your side, I am happy."

Chen Yuan slowly lay on the bed and looked at the familiar ceiling.

"In other words, if a person does not have dopamine, then there is no way to bring happiness?"

"Yeah." Ya slowly snuggled in Chen Yuan's arms.

Chen Yuan stroked Ya's hair.

This is why Chen Yuan could not feel happiness after becoming a celestial body.

Because dopamine is secreted from the brain, and Chen Yuan's consciousness is almost not connected to the brain.

So, he could not feel happiness.

Until now, Chen Yuan's consciousness is connected to the brain, and he can feel happiness.

The desire of the body and the happiness generated are connected together.

There is the current Chen Yuan.

So what is real happiness?

"Getting desire, getting desire, are these all happiness?"

Chen Yuan looked at Ya in his arms.

No... not right.

If dopamine is the essence of happiness.

Then happiness is actually a kind of material stimulation.

In other words.

Happiness has no meaning at all.

Satisfying desires can bring happiness.

And desire is the key to driving people to act.

"If humans have no desires."

"If people have no appetite, they will not grow food or hunt for food."

"If people have no desire to reproduce, then people cannot pass on, and the human race will perish."

In other words, desire is necessary for human development.

"It is not depraved to drive people to satisfy their desires and make them happy, or it is a need for human evolution."

Ya hummed: "However, human desires are endless. If you indulge in desires, you will destroy yourself. Desires cannot be eliminated, but they cannot be too indulgent."

She raised her face, looked at Chen Yuan, and said with a smile: "Suitability is the most important thing."

Chen Yuan hummed.

At this time, Chen Yuan thought of a question.

Before, the cosmic giant he met said that this world only has eleven dimensions, so is it really only eleven dimensions?

Beyond the eleven dimensions, is it really just the void?

Will you really die if you step in?

Will the cosmic giant deceive himself?

Chen Yuan had a little doubt.

This doubt must be verified.

But how to verify it?

There is only one way to verify it, that is to verify it yourself.

But if you break through the eleven-dimensional world and reach the void, your consciousness may disappear and you will die.

But Chen Yuan wants to go and see.

He has curiosity or a desire for knowledge, and a strong desire for knowledge urges Chen Yuan to take a look.

But... Chen Yuan subconsciously looked at Ya beside him.

Ya was looking at him, she smiled: "I know that this day will come eventually. What is outside the eleven-dimensional world, only you can verify it, and only you can see it."

"Sooner or later you will go." Ya raised her face slightly and kissed Chen Yuan's forehead. She showed that familiar smile: "I'll wait for you to come back."

Chen Yuan was slightly startled, he looked at Ya, he nodded slightly.

Consciousness left the body.

Restored to his original body.

His body turned into a cosmic giant.

He looked at the cosmic pool in front of him, raised his face, and looked up.

This cosmic giant is different from the human brain, that is, it has no emotions, nothing.

Chen Yuan looked around, the world in front of him was in the eleven-dimensional world.

Outside the eleven-dimensional world is the void.

"Let's go."

The huge body flew up.

Looking at the void above and flying away.

Time passed by minute by minute.

I don't know how long it has been.

Or ten thousand years, one hundred thousand years, one million years, or tens of millions of years or hundreds of millions of years.

Chen Yuan finally touched the dark void.

Crossed the dark border and stepped into the void.

When he entered the void.

Chen Yuan's huge body disappeared.

Consciousness also disappeared.

Nothing was left.

Twelve-dimensional space.

Is the end.

The world we know does not exist infinity, and everything has an end.

And the twelve-dimensional space is the end.

After entering this dimension, everything will come to an end.

The end of matter, the end of consciousness, the end of everything, this is the twelve-dimensional space.

What happened here.

Ya didn't know.

She was not in the eleventh dimension, and she couldn't sense what happened in the eleventh dimension.

Time passed little by little.

She waited for Chen Yuan as usual.

Ya stood on the balcony, looking at the starry sky.

She waited with expectation and a smile on her face.

But the waiting time was too long.

The universe died once, and she used the power of technology to bring death back to life.

Then the universe experienced death again, and she revived the universe again.

After three full times.

The smile on Ya's face completely disappeared.

She was still waiting, but she couldn't keep her consciousness.

She was afraid that she couldn't stand the loneliness and gave up her life. She wanted to continue waiting for Chen Yuan.

So, she chose to close her eyes and choose to sleep.

Just like that, I don't know how long it has passed.

The whole universe died.

Ya slept in this dead universe, and her body disappeared because there was no material supplement.

Only the consciousness body was left floating in this universe that had expanded to the limit.

In this universe where all celestial bodies have died, time seems to have lost its meaning.

After an unknown amount of time.

A voice sounded in Ya's ears.

"Ya."

Ya's thoughts came back.

Her eyelashes moved and she slowly opened her eyes.

She found herself lying on a familiar big bed.

Next to her, Chen Yuan was on top. He looked at her and smiled: "Awake?"

Ya's eyes trembled slightly, a glimmer in her eyes, and a smile appeared on her face.

She threw herself into Chen Yuan's arms, hugged Chen Yuan's neck, and closed her eyes.

"Welcome back."

Chen Yuan smiled and stroked Ya's hair.

"I'm back."

...

Twelve-dimensional space.

Is the end.

Matter, consciousness, all things that exist and do not exist, will usher in the end after entering the twelve-dimensional space.

But the end does not mean the end.

The end is also equal to the origin.

This is also the reason why Chen Yuan can come back.
