After things settled in the clinic, Li Youcai spared his efforts and was thinking about how to completely cure Wu Xiang's heart disease.

There are two types of heart disease, the first is congenital and the second is acquired.

According to Wu Tian's account, Wu Xiang did not have such symptoms when she was a baby, and this heart disease was acquired.

The so-called acquired heart disease is nothing more than the heart being affected by external or internal factors after birth. Such as: hypertensive heart disease, pulmonary heart disease, infectious heart disease, endocrine heart disease, blood disease heart disease, nutritional metabolic heart disease, etc.

According to Wu Xiang's condition, Li Youcai can almost determine that this is acute cor pulmonale caused by pulmonary embolism. How to resolve pulmonary embolism is the key factor.

The clinic was not open that morning.

Li Youcai took a bus to a dense forest in the suburbs, and when he walked into this wood, it was as if he had entered a labyrinth

This forest area is very large, about twenty or thirty acres in size, in order to avoid getting lost, Li Youcai deliberately used a blade to carve a clear cross mark on the trees he passed by, so that when he went back, he could walk along that road.

He came today to find a herb, this herb combined with other Chinese patent medicines, has a good effect on heart disease, if you insist on taking it, the patient's pulmonary artery is covered with a very fine film, which can effectively tissue embolism formation, so as to prevent heart attacks.

But this herb is not easy to find, it grows in a dark and damp place, and there are many trees, Li Youcai is also a hint of the big repair system, and he only knows about this herb, and he came today to try his luck to see if he can find the kind of red silk thread described by the big repair system, also known as blood sorrow. It is a rare herb that can be encountered but not sought.

The deeper you go into the woods, the thicker the trunk becomes, and the branches and leaves are more luxuriant, covering the sky and the sun, only a small ray of sunlight shines through the gaps and falls on the ground.

It turned out that I still felt the heat outside, and as soon as I came in, I felt a slight coolness, which spread around and inadvertently penetrated into every pore of myself.

"Red Silk Thread, Red Silk Thread, where are you, I'm looking for you so hard. After wandering around in the woods for more than two hours, Li Youcai didn't even see the shadow of the red silk thread.

It's also weird to say, the longer you stay in this dense forest, the more you can feel the slightest coldness from the depths of the woods, and Li Youcai even wonders if he will freeze to death if he stays here all night.

Although there are more and more markings on the trees behind him, there is still no trace of the red silk thread, but Li Youcai does not want to give up, he decides to go to the deepest part of the dense forest, he is not the kind of person who gives up easily, if there is really none, he will turn around and leave.

After walking for a while, Li Youcai really couldn't walk, he leaned against the big tree, sat down, and wanted to rest for a while.

As he was closing his eyes to recuperate, he suddenly heard a faint, high-pitched "hissing" sound. Although the voice was very small, Li Youcai's hearing was more keen, and he suddenly got up from the ground and looked around very alertly.

If he guessed correctly, this should be the tentative sound of the snake when it encounters the enemy, although the snake did not attack, but its reaction at least indicates that it has no good impression of an intruder like Li Youcai.

Li Youcai's eyes searched around vigilantly, and suddenly he saw that in the green grass not far away, there was indeed a seven-step snake coiled up, raised its head, spit snake letter in its mouth, and the strange snake eyes stared at Li Youcai motionlessly.

The seven-step snake is grayish-brown in color, similar in color to a withered branch, and can be used as a good cover when hiding in the grass.

When Li Youcai saw the seven-step snake, his scalp was numb for a while, and his vest was almost sweating.

The seven-step snake is just a colloquial name for this snake species, and its scientific name is Sharp-nosed pither. It is known for its pointed snout and the triangular shape of the snake's head. This snake is said to be very poisonous, and if a person is bitten, he will die if he walks out of the seven parts. Of course, this is somewhat exaggerated, but it is enough to prove that its toxicity is very strong, and it is no joke to be bitten by it.

Soon, as more "hiss" sounded in the jungle, Li Youcai found that there was far more than this seven-step snake nearby, and Li Youcai estimated slightly, just within a radius of ten meters, there were at least more than ten such seven-step snakes.

"Damn, I'm in the snake's den today. Li Youcai gasped and muttered to himself.

But why are there so many seven-step snakes in this area alone? Li You knew that snakes are a lone animal, and rarely gather together on a large scale, and if this is the case, then it can only be that there are things that they regard as precious nearby.

That's right, the red thread!

Li Youcai suddenly thought of something, when he came just now, he learned from the big repair system that the red silk thread is bitter and cold, and it will emit a smell that attracts seven-step snakes, so there are usually seven-step snakes gathered near the red silk thread.

Li Youcai was startled just now, but he didn't realize this problem, Li Youcai is not afraid of heaven and earth, but he is afraid of snakes!

After Li Youcai stood up, he carefully moved his steps, first, he wanted to keep a distance from those seven-step snakes, and second, he wanted to take the opportunity to find the red silk thread.

He had finally come to this place in this dense forest, and it would be more painful for him to return in vain than to be bitten by a snake. And even if he is bitten by a snake, he can still have a big repair system, which is nothing more than spending some money.

Li Youcai's scalp was itchy at this time, a little wind and grass were clear, his eyes flickered, and finally he saw a flower more than 70 centimeters tall next to a bush, with roots in strips, and when he looked at the rhizome carefully, there was a red silk thread that meandered on it, along with the roots and petals. Five yellow petals, star-shaped, bright eyes, quite eye-catching!

It was the red silk thread, although Li Youcai's eyes lit up, but until dozens of highly poisonous snakes were staring at him around him, he really couldn't be happy!

This herb has been found, but how to pull it up and get out is a problem!
