Without saying a word, Xu Xin jumped onto the rusty iron ladder and climbed up with all his might.
Isn’t that red gas the same red smoke that was so smelly that made people doubt their lives when it came out of the iron door of the underground passage when he just opened it?
The smoke will float upwards and will definitely spread upwards along the passage until it fills the entire passage!
He absolutely cannot be caught up by this smoke. Whether it is poisonous or not is another matter, but he never wants to smell the smell that is like the poop of canned herrings from hell again!
Climb! Climb!
With the little panda Koko lying on his shoulders and a golden treasure chest on his back, Xu Xin climbed up madly as if he had been injected with hormones.
Xu Xin, carrying the golden treasure chest on his back, felt like he was running with a heavy load. However, when he thought of the pattern on the treasure chest, he finally gritted his teeth and did not throw the golden treasure chest away.
He didn't know how long he had been climbing, he only knew that his hands and feet were almost numb.
Finally he couldn't hold on any longer and hung on the rusty iron ladder, gasping for breath.
He looked back with horror.
However, what surprised and delighted him was that the red mist did not follow him, but was far below. Xu Xin, who had night vision, could barely see the faint red color below.
The red gas seemed to spread much slower than he had imagined.
Xu Xin breathed a sigh of relief, sat down on a ladder and began to rest.
Eat something before that red gas comes up.
Xu Xin took out an apple and started eating it, and gave one to Coco.
Coco also started to eat the apple on his shoulder.
After the man and the little panda had eaten and drunk their fill, Xu Xin was almost done resting.
He felt his body with some surprise. In the past, after strenuous exercise, he would never have recovered so quickly. Now his physical fitness was really different from before.
Glancing down, I saw that the red mist was getting a little closer, but it was still quite far away.
However, Xu Xin did not waste time and continued to climb up.
Only when he returned to the ground and stepped on the land protected by the tree house could he feel a little at ease.
Continuing to climb, Xu Xin maintained a good rhythm this time, no longer flustered like before, and got closer and closer to the exit step by step.
After climbing for a long while, just when he felt he was about to reach the exit, Coco on his shoulder suddenly started to cry, her voice full of anxiety.
"What's wrong?" Seeing Keke so anxious, Xu Xin turned around and looked at her.
Then he was shocked!
That flash of red was actually very close to him, only five or six meters away.
What's going on?! How did it spread so quickly?!
In just a moment, Xu Xin figured out the underlying principle. The red gas did diffuse slowly, but that didn't mean it was being released slowly in the room below. As long as the release speed increased, the concentration of the red gas would increase, and the pressure would increase, so the diffusion would naturally accelerate!
"Fuck!" Xu Xin cursed angrily and increased his speed in climbing up.
He learned his lesson this time and no longer used all his strength. Instead, he maintained the rhythm. However, the extremely fast speed still made his body a little overwhelmed, and his breathing gradually became disordered.
While crawling, Xu Xin looked back from time to time. The red color was getting closer and closer to him, and was only two or three meters away!
"I see the exit!" Xu Xin became excited and started climbing up with all his strength, no longer caring about the rhythm.
Just before the red fog behind him was about to catch up with him, Xu Xin rushed out of the iron gate, then used up the last bit of his strength to lift the heavy iron cover on the other side and slammed it down on the exit.
"Bang!"
A few wisps of red smoke emerged from the last crack in the iron cover, while the rest was trapped beneath the iron cover, within that incredibly long passage.
The wisp of red smoke entered Xu Xin's nose.
"vomit--"
Just a wisp of it made Xu Xin feel nauseous. He couldn't believe what would happen if his whole body was immersed in that red smoke.
Sitting at the exit, Xu Xin was breathing heavily. Due to excessive climbing, his arms and legs were shaking and his head was a little dizzy.
Coco lay on his legs and looked at him with her head tilted, as if to ask him why he was so tired.
"Little thing!" Xu Xin rubbed Coco's head in annoyance.
After resting for a few minutes, Xu Xin felt his strength gradually recovering and stood up.
Walking out of the passage, the sunlight shone on him. It was already bright outside.
After staying in a relatively dark environment for so long, Xu Xin suddenly saw the light, which was a bit unbearable for his eyes, so he blocked the sunlight with his hands.
After gradually getting used to it, he looked at the ordinary plants on the ground and finally smiled with relief.
The world below was truly oppressive. The physical and mental strain and impact on him along the way never ceased. Having seen the monsters of the underground world, Xu Xin now even found the beasts above ground so adorable.
The surrounding area is still the wasteland left after the yellow flowers withered.
"Go home, go home!" Xu Xin now wanted to go back to the tree house and have a good sleep.
Although his orange (blue) kept him in a relatively excited state, his physical and mental fatigue had reached its peak. He didn't want to do anything now and just wanted to lie on the bed and do nothing.
It would take him about an hour to walk back from where he is now.
"Oh... When can I get a means of transportation?" Xu Xin thought that there was still an hour's journey to go, and his legs, which had just relaxed, began to ache again.
