Su Mei listened quietly to Lu Yuan’s story. At this moment, she truly understood the meaning of the so-called knowledge is power.

And when she looked at this shoddy and simple world, she naturally experienced this almost timeless beauty from it.

She also understood why the natural base e is the answer to this puzzle.

If you contact the picture of the evolution of life on Earth that you first saw on the bronze gate, and look at the world, just as Lu Yuan said before, this is like the first breeding ground for cultivating life on Earth.

Countless lives will be born in this hot pool, and then fight and evolve with each other, trying their best to pass on their genes and let their descendants occupy the world.

Su Mei naturally remembered the earth she knew, the earth full of life everywhere, which was in sharp contrast with the desolate and dead world in front of her now.

And between this comparison, there is this code of life that is timeless.

Between the dead and cold world and the world full of vitality.

The natural base e is the evolution key that is closest to the answer.

It is also the reason why Lu Yuan chose this nearly eternal number as the answer to this puzzle.

Su Mei looked at the door radiating a glimmer of light in front of her again. It was born in the center of this big stone where the correct answers had been written.

Su Mei believed that as long as he could walk through it, he could get the truth behind the bronze door, or at least one step closer to the truth.

"Let's go." Su Mei grabbed Lu Yuan's hand and said.

Lu Yuan nodded and the two walked into the shiny door together.

The moment he walked in, Lu Yuan felt that his body was slowly approaching lightness to nothingness.

In the next moment, he felt like he was in the universe, and his body was surrounded by a starry sky with nothingness and splendor.

"Su Mei?" Lu Yuan subconsciously called Su Mei's name.

Su Mei immediately responded to Lu Yuan: "Where is this?"

"I don't know." Lu Yuan confessed.

Everything in front of him almost destroyed Lu Yuan's most basic understanding. He seemed to be standing in the starry sky, with countless gorgeous stars on his head and countless gorgeous stars on his feet, but he could not move and could only float in the void.

At this moment, an ancient voice sounded in the minds of the two people at the same time.

"Continue?" the voice asked.

It seems to be a coincidence between countless languages ​​and countless tones, so it sounds overlapping and desolate.

"What to continue?" Lu Yuan asked subconsciously.

"Continue this exploration." The voice said.

"What if I don't choose to continue?" Su Mei said.

"Then you will return to the original world and accept the annihilation of your civilization." The voice was very calm and distant.

"So can we still come in?" Lu Yuan asked.

"Of course," the voice said, "Your challenges and adventures are welcome at any time as long as you are still alive."

"Since that's the case." Lu Yuan sighed: "I chose to leave for the time being."

"Okay." The voice replied with a faint smile: "I believe you will come back."

After saying this, Lu Yuan and Su Mei fell into a coma at the same time and lost any consciousness.

...

...

All this seemed to be only a moment. When Lu Yuan came to his senses, he and Su Mei were still standing in front of the bronze door, their bodies were so hot that they could not bear, and their faces were covered with masks used to filter sulfur dioxide and other toxic gases.

Lu Yuan tightened his hands tightly, feeling that the tentacles were warm and delicate.

He looked at the opposite side, and Su Mei also looked at him.

Two people looked at each other with four eyes, and for a moment, they were mixed with emotions.

"I think we're back." Lu Yuan said.

"I think so." Su Mei nodded and said.

The two of them turned around and saw the tall black doomsday mecha still stopped behind them.

"What are we going to do now?" Su Mei asked.

"I think at least I shouldn't go in easily anymore." Lu Yuan said: "Since you can come out, it's a valuable experience."

"Let's go back first and continue to discuss with John Smith and Roland."

Before the two of them finished speaking, Su Mei heard heavy footsteps coming from a distance little by little.

Since there is almost no human existence in the world at this time, and there is almost only one kind of existence with such heavy footsteps.

Su Mei immediately understood: "Is this John Smith coming?"

"It should be." Lu Yuan nodded and said, "Maybe he is worried about us."

As he said this, Lu Yuan reached out and pressed the earlobe - after he came out, the Transportation Commission had been able to operate again, and of course he could send electromagnetic waves to contact John Smith: "Is it John? Lu Yuan here, you seem to have come down? Are you?"

John Smith's surprise voice came from over there: "Lu? Are you still alive?"

"Of course I'm still alive, where are you now?" Lu Yuan said with a smile, actually feeling a little warm.

After all, some people care so much about your life and death, saying they don’t care at all is deceiving themselves.

"I'm almost at that so-called bronze door, and with Roland, I've now known everything about the bronze door."

"And." John Smith paused, his voice choked for a moment; "And I thought you were almost dead."

"Take Roland with you?" Lu Yuan was a little surprised: "Did Roland say something else?"

"Yes, and not some, but a lot," said John Smith. "But it's a long story. How are you doing now? Are you injured and need support?"

John Smith asked a lot in one breath, and he was really sincere and caring.

Lu Yuan shook his head and said, "We are fine for the time being, the Doomsday Mecha is intact, so you can go back to the base before talking."

“We also have a lot of stories to tell.”

"And there may be many unknown truths behind this bronze door, and the key to whether we can revive human civilization."

Lu Yuan said seriously.

"Well, I heard a lot from Roland, and I plan to see the bronze door with my own eyes."

"Roland has already said that as long as you don't enter the bronze door, just just look at it, there is no danger."

Lu Yuan nodded: "Yes."

"Then come here."

The two stood side by side, waiting for John Smith's arrival, only to hear the heavy footsteps getting heavier and heavier, and as the bright light swept across like a sharp sword, Lu Yuan saw the tall Doomsday mecha holding Roland in a cold-proof suit in the hands of the tall Doomsday mecha. He brought Roland over with him as John Smith said.

John Smith also saw the tall bronze door and the two people standing under the bronze door.

He exclaimed incredible surprise.

"No."
