This shows that the dark yellow viscous liquid is very corrosive to metal substances, no wonder there are holes in the bottom of the tin bucket, and those poisonous scorpions are also drilled out of the holes.

At the same time, Han Du also found the reason for the sudden rise in temperature in the vicinity, and those high temperatures must be related to the dark yellow viscous substance, perhaps directly from the dark yellow viscous substance, or it may also come from the chemical reaction between other substances that produce the dark yellow viscous substance, because these dark yellow viscous substances definitely do not exist directly.

Han Du brought the tin bucket to Yan Ruyue, and her pale face already roughly understood what was going on.

"Could the viscous liquid on this be naturally occurring sulphuric acid? How is this how the tin bucket is corroded? ”

Facing Yan Ruyue's question, Han Du shook his head and said: "It shouldn't be, there is no naturally formed sulfuric acid, because sulfuric acid is easy to react with other substances in the natural environment, but it is certain that this is a substance with similar characteristics to sulfuric acid, and it is likely that there are other unknown substances in the ground, and they react with each other because of some factors, emitting high temperatures, and producing a viscous liquid that corrodes the iron bucket." ”

Yan Ruyue agreed.

Although the unknown substance underground still needs to be explored to know what it is, this is a matter that has nothing to do with the trial mission, and Han Du has no intention of exploring it.

"Let's continue our journey to the third mission location, and I'll take you back for treatment as soon as it's done."

After Han Du finished speaking, she barely stood up, and she was still able to walk around on her own.

Originally, Han Du planned to carry her on the road, because he knew how bad Yan Ruyue's real situation was, but considering that there were many inconveniences between men and women, he didn't say anything.

Han Du put the borrowed gasoline drum into his mountaineering bag and took Yan Ruyue to find the only big river nearby in the forest.

According to the introduction of Trial Quest 3, there is a special big fish with four short legs in the river, which is the last challenge that Han Du will face, and he needs to arrange it there again when the time comes.

"Han Du, I'm so tired, when will I get to the third mission location you mentioned?" After walking around in the forest for more than twenty minutes, Yan Ruyue couldn't help but stop and leaned on a big tree to catch her breath.

"Don't worry, as long as we find a place with a river, we can start the third mission."

Han Du continued to look into the distance, and now only by discovering the river as soon as possible could Yan Ruyue have a chance to get out of danger.

As his eyes searched around, he suddenly noticed that next to a large tree opposite, there were many coniferous, crimson dwarf plants, which looked like miniature coniferous cedars, but they were clearly recognizable as other species of plants.

Han Du's mind suddenly shook, and a picture of a plant that was exactly the same as this plant, the name of Blood Fir Grass, appeared in his mind.

This was a plant recorded in the Encyclopedia of Expedition Knowledge that Han Du had obtained, and a stream of information about the blood cedar grass appeared, and he immediately had a comprehensive understanding of this plant.

It turns out that blood fir grass is a plant with detoxification effects, if someone is bitten by a poisonous insect and poisonous snake, put its crimson needles in the mouth and chew it, and apply it to the wound, which can have a good detoxification effect.

Han Du was overjoyed, ran over, pulled up a blood fir grass, picked up the needles on it, and put it in his mouth to chew, the taste was a little numb, and there was a cool aroma coming out of it.

Yan Ruyue dragged her weak body over, not understanding what Han Du was doing, and asked, "Have you degenerated into a herbivore?" ”

Han Du shook his head, continued to chew the blood fir grass needles in his mouth, and then took it out and kneaded it into a ball, and then he was very happy and said: "Writer Yan, you are saved, this plant is called blood fir grass, and it can detoxify your wounds." ”

Yan Ruyue didn't expect that Han Du had found an antidote for himself, and stared at the chewed needle in his hand and confirmed, "You mean to put this mass of things taken out of his mouth and apply it to my wound?" Don't you feel disgusting? ”

Han Du glanced at her and said, "Miss, you can be content, it is your great blessing to have someone like me who thinks about your safety." ”

Although Yan Ruyue said this, she actually did not reject Han Du from putting something chewed on her hand with her mouth, because she felt that her situation was very bad, and she originally thought that as long as she boiled it, she would be able to get through.

"Come on, if such a dirty thing can't be detoxified on my hands, see how I clean you up later." Yan Ruyue stared at Han Du and stretched out the hand that had been bitten in front of Han Du.

Han Du knew that she was just talking about it, and he didn't bother to pay attention to her, but when he saw the back of Yan Ruyue's hand, the originally red and swollen piece on it had begun to turn black, indicating that the poison had worsened, no wonder Yan Ruyue felt that he was about to be unable to support it.

He immediately pressed the crumpled medicine ball on Yan Ruyue's wound and flattened it, she suddenly let out a slender moan, feeling that the substance in the medicine ball made her wound feel like a small piece of ice had been put into it, and then there was a tingling and cold feeling spreading from her wound, and there were originally some pain symptoms in it, but now it is gone.

What's even more surprising is that the wound that has become black slowly turns back to red and swollen, and the effect is immediate.

Yan Ruyue was already overjoyed, and hurriedly thanked: "Han Du, you are god, the effect of these herbs is much stronger than the antidote drugs produced by modern technology, the old lady thank you on behalf of my millions of readers." ”

Han Du patted her skull and said with a smile, "You represent really wide enough." ”

Yan Ruyue didn't care at all, pressed the medicine on the back of her hand, and smiled at Han Du: "Go on, this medicine doesn't seem to be enough, it's good to apply a little more." ”

Han Du pulled up a blood fir grass, picked up the needles on it, and handed it to Yan Ruyue: "Isn't it disgusting that I chewed the medicine ball, you can chew it yourself." ”

In fact, Han Du was not aimed at her, but with a good heart, if she chewed the needles of the blood fir grass by herself, some of the medicine would enter the body through the mouth, and with the medicine applied to the wound, the effect should be better.

"Stingy, didn't you just say something casually, are you still serious?"

After Yan Ruyue finished speaking, she took the needles by herself, put them in her mouth little by little and chewed, it turned out that these needles were very soft and not as hard as she imagined.

Yan Ruyue chewed a ball of herbs by herself and applied it to the wound, and then Han Du tore off a strip of cloth from under her shirt and wrapped the two balls of medicine on the back of her hand.

In this way, Yan Ruyue's wound can be considered to be dealt with, and she can free her other hand.

Han Du saw that there were still a lot of blood fir grass at the scene, so he collected five and put them in his mountaineering bag, planning to take them out to use, maybe when they could be used in an emergency.

After that, he took Yan Ruyue to continue to set off, looking for the only river in the forest, but the vast mountains and forests, it was all up to luck to find the river, they walked for almost an hour, and still found nothing.
