Fortunately, in the middle of the mountain, the rain all day did not cause floods to submerge Mu Heng's roots, but the rain washed down carried quite rich nutrients, making Mu Heng grow exceptionally strong.

Shrouded in dark clouds, the sun is not very abundant, so Mu Heng can only use this part of the nutrients to tamp his branches. Since having Tu Su's company, Mu Heng's life has changed greatly, and he has more motivation to look forward.

Tu Su seemed to be very cold, and Mu Heng's accosting didn't cause her much fun. Most of the time, Mu Heng was still talking to himself, saying inconsequential words.

Listening to Tu Su's ears, it was like a book from heaven, what planes, trains, aircraft carriers, I don't know where I heard strange words.

"Didn't the iron sink quickly when it fell into the water, why did this thing called an aircraft carrier float on the water?" Tu Su and Mu Heng started daily communication again.

It's only when it comes to things she hasn't been exposed to that she's the slightest bit of interest.

"Well, it's just buoyancy dragging it. Just as wood can float on water and not sink, iron can float if the average density of iron is reduced below the density of water. Mu Heng patiently explained.

"What is density?" Tu Su understood Mu Heng's explanation, but he couldn't understand what he meant, so he grabbed the most critical word in his words and asked rhetorically.

"Density is the ratio of mass to volume."

This kind of question and answer frequently appears in the daily life of Mu Heng and Tu Su.

The time came 400 years after the earthquake caused the landslide. As time went by, the relationship between Mu Heng and Tu Su became closer and closer.

"Hey, why are you here?" Tu Su asked with some restraint.

"Me? When I think about it, it seems like hundreds of years ago. Mu Heng was stopped by this question.

If you think about it, it's been 900 years since you became a tree. In his previous life, he had only been on Earth for more than twenty years, and he had only traveled to the other world for just over two months, which was too insignificant compared to the next nine hundred years.

"I remember that I was a person, a young handsome young man, loved by everyone, and the kind of flowers that bloomed." Mu Heng's eyebrows fluttered and told her about his past.

"Gross. I don't know how to praise myself so much. "Tu Su doesn't seem to be very strange, Mu Heng used to be a human thing.

"Aren't you curious how I ended up like a tree?" Mu Heng was a little surprised by her reaction. Could it be that she herself is strange, and she is not strange to others?

"What's so strange, it's just like that." Tu Su said in an old-fashioned manner.

"Well, I'm wrong. Go on, I've been killing all sides before, and I've already won the championship. It is precisely because of his outstanding talent that he was coerced and tortured. But I, Mu Heng, is he greedy for life and afraid of death, and would rather die than obey, and then somehow became what he is now. Mu Heng vaguely remembered that he was almost dead at that time, but he still didn't give in.

"I can't see that you're still a righteous man." Tu Suyan couldn't help but admire.

"Why, don't you look down on me?" Mu Heng was not happy when he saw her attitude, and then added: "Although I, Mu Heng, am not a big person and have no extraordinary ability, I can restrain myself, and I know very well what to do and what not to do." What should be done will not be evaded, and what should not be done will not be compromised. ”

"I believe in you." Tu Su saw that Mu Heng's tone was a little heavy, and he also put away his cynical arrogance.

"Thank you."

-------------------------------------

"Tu Su, do you know what kind of place this is?" Mu Heng still doesn't understand how a person who is good and good can become a tree, and why he appears in this place. Considering that Tu Su was born and raised here, he wanted to ask her.

"I don't know, I'm a rock, I can know something." Tu Su replied as if rolling his eyes.

As an old friend who has been with each other for 400 years, Mu Heng can feel her expression just by using his heart.

"That's right. Count me asking the wrong person. Mu Heng once asked this question, but he didn't get an answer.

"Have you ever thought that maybe this is not a world?" Tu Su said cautiously to Mu Heng.

"Not a world? What is the meaning? Mu Heng didn't understand what she meant, and wondered.

"I can't tell, you can only think for yourself." Tu Su raised his head, but he didn't want to say more, which made Mu Heng unable to go up.

It's the most annoying thing to talk about half-cut. Mu Heng felt that Tu Su seemed to have a certain understanding of this place, but he was reluctant to tell himself.

Thinking about the essence of Tu Su, Mu Heng felt a trace of solemnity in his heart. From then on, Mu Heng never mentioned this kind of problem to Tu Su in the future.

In the next hundred years, Mu Heng still chatted with Tu Su all day long about his past and present lives, as well as doubts about the problems of mathematics, physics, and chemistry.

But Tu Su, who was in the clouds, couldn't keep up with Mu Heng's rhythm at all. She is accustomed to being an audience, and she will not refuse to listen, and she will be a monk chanting scriptures.

"Hey, do you like the days now?" One day, Tu Su looked at the sunrise in the east and asked with Mu Heng behind his back.

That's a good question. As a human being, I must hate the current life, I can't walk with my feet, I can't do things, and I can't see people. Thinking of his parents and relatives in his previous life, as well as Ye Qingyin, Luo Yunjin, and Liu Qing'er, Mu Heng felt gloomy.

"What about being a tree?"

"As a tree, it grows alone, and although it encounters disasters, it still survives, and it seems to be quite happy. However, as a tree with human consciousness, it is impossible to truly enjoy such monotonous and boring misery. Mu Heng chuckled, recalling the lonely situation of the first five hundred years in his mind, and didn't want to repeat it anymore.

"And what if you still have a chance to become human again?" Tu Su followed and asked.

"Becoming human again? That..... Hey, why do I feel the mountains moving? Before Mu Heng could think about this, the movement under his feet interrupted his thoughts.

"Huh?" Tu Su didn't know why, so he could only follow Mu Heng's "gaze" and look up.

"Damn, the flash flood broke out, and I'm going to die, I'm going to die. No, I'm a tree, I can't die. "The torrent rushing out of the mountain col in the distance rushed towards Mu Heng's side.

"Tu Su, hurry up, don't get separated." Mu Heng took advantage of the fact that before the torrent arrived, he grabbed Tu Su tightly and did not relax.

The mountain rock was impacted, and it also became partially weightless, and with the buoyancy of the flood, Mu Heng was easily pulled out of the stone crack.

"I don't know where this water is going?" Mu Heng, who was floating on the water, wandered aimlessly with the current.

"Tu Su, are you okay?" Mu Heng asked with concern.

"I'm a rock, what can I do. But you, with only a bare trunk left, can you still live? Tu Su's tone was also full of some concern.

"It's fine. Haven't you heard a saying that wildfires can't be burned, the spring breeze blows and grows, the roots are not all broken, and you can live when you land. Mu Heng smiled arrogantly.

-------------------------------------

Torrents come and go fast. In three months, Mu Heng fell from the water to the land.

"What the hell is this weather, it's hot and dead." Mu Heng lay on the ground, looking at the scorching sun in the sky, sweating profusely.

I thought that there was no strong wind at the foot of the mountain, no rain, and it should be lush under the rising sun, but I didn't expect that it was indeed a desert. The fiery red sun scorched the earth unscrupulously, and at the same time scorched Mu Heng.

Although he didn't feel pain, Mu Heng could still clearly feel that his vitality was passing. I don't know what breed I am, but I have some resistance to such a harsh environment.

Perhaps the vitality accumulated before was too large, and Mu Heng worked very hard to control the loss rate, so in a short period of time, it could not have a great impact on Mu Heng.

In such a situation, Mu Heng reduced his communication with Tu Su and tried to extend the time with her.

In the blink of an eye, another 500 years. Mu Heng's bark had almost fallen off. There is no vitality in the whole body, and it looks like a dead tree.

With only a little vitality left in his body, Mu Heng realized that he was dying, and it was time to leave. Looking at Tu Su in front of him, Mu Heng was suddenly a little reluctant to leave alone.

"Tu Su, are you there?"

"Hmm."

"With your company, I am not alone in these 1,500 years." Mu Heng recalled the wind blowing in the first 500 years, the rain in the middle 500 years, and the sun in the last 500 years.

"Hmm."

"I'm leaving."

"Where to go?"

"I'm going to die."

"Oh."

"If you're left alone, will you feel lonely?"

"No, it won't."

"It's so unconscionable."

"Will you forget me?"

"Yes."

"It's really a stubborn stone, just like when I first met you, it's so naughty."

"It's a pity that I can't take you away, otherwise I won't let you go."

"Who is rare."

"Sa've got Lala."

“。。。。。。”

After consuming the last trace of energy, Mu Heng closed his eyes peacefully, and with great nostalgia, he withdrew his consciousness to his brain.

When I opened my eyes again, the first thing I saw was the appearance of the national teacher's immortal wind bones. The corners of his mouth were filled with the smile of the victor, and he teased: "Figured it out? ”

Mu Heng spread his hands, not wanting to answer this question. I've already come out, the meaning is not very obvious, and I knowingly ask what to do.

"I don't think you seem to want to come out, why did you come out again?" The national teacher looked strange, touched his beard and asked.

"You have to take care of it." Mu Heng didn't give him a good look, but Tu Su's figure appeared in his mind.

"You're really trying to help me? Don't worry about me targeting the Terrans in the future? ”

"You're really verbose, if there's anything to call as soon as possible, otherwise I'll leave."
