For a few hours, Yang Laoshi spent all his thoughts on the snake hyacinth poisonous weed, and after his careful study, coupled with his deep understanding of various medicinal herbs, he finally solved the doubts in his heart!

The poisonous weed of the snake hyacinth is the name he gave to this grass, and it was named so because it resembles the snake hyacinth.

This grass contains highly poisonous, and wherever it grows, it will exude an invisible and tasteless poison all the time, that is to say, the area that Yang Laoshi discovered before was shrouded in poison all the time!

And this kind of poison, after Yang Laoshi's experiments, is ineffective against vegetation, only on animals!

This is also the reason why the bird that suddenly broke in turned into a pool of blood, while the surrounding vegetation was not affected by the poison, because the poison had no effect on the plants at all.

The vegetation in that area grows far more lushly than in other areas, because all the animals that pass through that area are turned into fertilizer in that area, and it is difficult for vegetation to flourish or not.

Because Yang Laoshi's body is very resistant to poison, after entering that area, he didn't feel anything wrong with his body, plus this poison is invisible and tasteless, so he didn't find it, only after he took the snake hyacinth poisonous weed, the poison broke out violently, and the body would react.

Niu Da that day should have been close to this area, but he didn't go deeper, so his body was slightly infected with a little of this poison, which caused Niu Da's body to not immediately turn into a pool of blood, but quickly began to fester.

After that, Niu Er and Niu Simei fed him traditional Chinese medicine with a family prescription, so that the toxicity was temporarily alleviated, and Niu Da persisted until Yang Laoshi appeared.

The wild boar found today also did not go deep into the area where the snake hyacinth poisonous weed is located, but the poison it was infected with was far greater than that of the cattle that day, so the wild boar would go berserk, and in the end, the poison attacked in the body, and it still did not escape the tragedy of turning the body into blood.

After Yang Laoshi's analysis, he came to a conclusion, that is, a small amount of infection with this virus will make the infected person's whole body quickly ulcerate and go insane. A large number of infections will directly cause the infected person's body to turn into a pool of blood!

This is the result of Yang Laoshi's harvest in a few hours.

"How is it, did Second Brother Yang get what you wanted?" Seeing that the returning Yang Laoshi was safe and sound, Niu Er breathed a sigh of relief in his heart, and at the same time, he also asked Yang Laoshi.

"Hey, hey! Of course, hours have been spent, can you go home empty-handed? Yang Laoshi smiled, and the look on his face was full of pride.

"What did you get? What about things? Niu Er asked with a puzzled face, Yang Laoshi, who was standing in front of him, obviously came back empty-handed.

"Uh...... Well...... Yang was stunned for a moment, and then said with a smile: "My harvest is experience, and I know a medicinal herb, as for the specific object, I haven't gained it, hehe." ”

"Oh, I see, so what are we going to do now?" Niu Er asked.

"It's this time of the afternoon, of course it's home, and there's still a long way to go. I didn't eat lunch at noon, and if I didn't go back, I was afraid that dinner would be eaten as a supper. Yang said honestly.

"Okay, then we'll go back now."

"Well, it's just a pity for that wild boar, otherwise we could have held a bonfire in the village at night and roasted and eaten the wild boar."

“……”

The two of them chatted as they walked back the way they came. It's just that what Niu Er didn't know was that Yang Laoshi did not return empty-handed, all his gains were put into the Sumeru space by him, and Niu Er couldn't see it at all.

Yang honestly said that what he gained was experience, and he really believed in the knowledge of new herbs.

The two left, and the area where a large number of snake hyacinth poisonous weeds grew, all the snake hyaccia poisonous weeds, had disappeared, and not a single one was left.

And this area, the forbidden place in the eyes of animals, after a month, all the invisible poisonous gases disappeared cleanly, and there was no longer the slightest residue.

However, for several months, the beasts and other animals in the mountains still did not dare to approach this area.

Back in Niulan Village, it was already evening, Niu Simei was already waiting anxiously at home, and said that she would come back at noon, and it was evening when she waited, and the anxiety in her heart could be imagined.

The last time his eldest brother went to such a place, he was poisoned, and Yang Laoshi and his second brother did not come back for a long time, so he had to wonder if there was an accident.

There is also a big brother at home who needs to take care of himself, and even if he is anxious, it will not help, and it is impossible to go to the mountains to find out, so he can only be anxious at home.

It wasn't until the figures of the two appeared in her sight that the stone hanging in her heart was truly put down.

Back at the dilapidated thatched house, Yang honestly checked Niu Da's condition and found that it was much better than when he left in the morning, which also proved that his medicine was indeed effective.

Dinner, Niu Simei was in charge, and the ingredients, of course, were brought back from the county by Yang Laoshi yesterday.

The dinner is very beautiful, Niu Simei's cooking skills are good, because everyone is in a happy mood, the dinner atmosphere is quite harmonious, and the three of them have smiles on their faces.

After dinner, Yang Laoshi took out three pictures with medicinal herb patterns and handed them to the two siblings.

These three pictures are the three medicinal materials that are still missing in refining the six-grade strengthening elixir, Red Heart Grass, Red Flame Fruit, and Centennial Tai Sui.

In doing so, it is Yang Laoshi who wants to let Niu Er and Niu Simei pay attention to it, if they find these three herbs in the mountains, they must help collect them for him, they are in the mountains, it is inevitable that they will often enter the mountains, if they are lucky, maybe they can really bump into these three medicinal materials.

Because he told the names of the two siblings, the two siblings might not know these three medicinal herbs, so he chose to use a picture to let the two siblings know.

For Yang Laoshi's request, of course the two brothers and sisters will not refuse, they are worried that they don't know how to repay Yang Laoshi, now that they have the opportunity, how can they be willing to miss it.

Without any accidents, the two siblings agreed.

In the middle of the night, the whole village of Niulan became quiet again.

There is no child's playing, no dog barking, and no reverberating mountain songs.

In such an environment, Yang Laoshi quietly left a sum of money for the three siblings, and then wrote a letter, and left Niulan Village unconsciously.

There is not much money left, only about 10,000 yuan, which is still taken by Yang Laoshi when he went to the county seat.

More banknotes, Yang honestly has, but he didn't leave too much, because leaving too much is not necessarily a good thing, but in his opinion, it is a bad thing.

The letter is a farewell letter, and at the same time, the letter also tells Niu Er to go to the county town to buy a mobile phone when he is free, and he can call him when he has something. The phone number, Yang Laoshi also stayed.

Finally, Yang Laoshi also cautiously reminded that the area where he went today, don't step into it again within a month, lest you get infected with the poison again, although there is no snake hyacinth grass there, but there is still a poisonous residue. Once infected, the damage to the human body is also not small!

In this way, he left the first small village he came to after coming out of the Seven Control Academy, Niulan Village.

After leaving Niulan Village, Yang Laoshi rushed to the county seat overnight, and he wanted to search the county town again to see if he could find the other three medicinal materials he needed.

The last time I came to the county seat was too hurried, I didn't have time to carefully find what I needed, and this time the matter was dealt with and I was no longer in such a hurry, maybe there would really be something to discover.

With such a fluke mentality, Yang Laoshi rushed to the county seat overnight, and then found a hotel to stay temporarily.
