Gu, the same as ancient.

Gu is the earliest witch skill that appeared in the ancient times, so it represents the oldest meaning.

Because at the beginning, various large beasts were not the biggest danger of the tribe, and the biggest harm was those small insects. Various poisonous insects were hard to guard against. At the beginning, the most people died inexplicably on these little ones, and they were endless. Later, some people found that they used vessels to trap these poisonous insects. When some were around, the probability of other poisonous insects appearing was much smaller.

Then he began to catch poisonous insects with him, just to protect himself.

Later, it gradually developed. Some people found that putting some different types of poisonous insects together will bite each other and turn into a new poisonous insect. Some are fierce and can drive out all nearby insects, some can suck out the toxins from the poisoned person, and some are even a holy medicine for detoxification.

However, afterwards, more and more developments were developed, and he began to study attacks with his own care. Later, the Gu was almost used to attack and harm people. Not only the only ones that harm people were harming people, but very few such as Tongxin Gu were left behind.

The young man's body is already considered a Gu worm, but he has no master, no one has cultivated him, and he has grown up completely autonomously. When the Gu worm dies, he will only recognize one master. This is also the reason why Ye Yuan immediately left after he first discovered this Gu worm. If he wants to get rid of this Gu worm, he will inevitably form a life-and-death hatred with the Gu worm. For the sake of a person he doesn't know, and when he is so low in strength, Ye Yuan is not so noble and does not have any brainlessness.

But now it seems that it is possible to take action.

The young man looked at Ye Yuan silently and couldn't help but feel nervous. Parasites can basically be ignored, especially those who practice martial arts and strengthen their bodies. The qi and blood are strong enough that any harmful things can be directly burned by qi and blood in their bodies. There will basically be no harm, but as long as one appears, it will be more serious.

"Doctor Ye, can I cure this?"

Ye Yuan nodded and said, "It can be cured, but it's quite troublesome. You can stay here today. It takes at least one day to cure it."

The young man was stunned when he heard this and was immediately overjoyed. He thought it would be a long time, but who thought it would take only one day to cure it.

"Doctor, you tell me how to do it, I will listen to you!"

Ye Yuan said: "I'll go to make medicine, and you ask your guard to go to the kitchen to burn a large bucket of hot water."

After saying that, Ye Yuan walked directly to the medicine warehouse in the house. This time he needed a lot of medicinal materials, and there were many more unpopular medicinal materials, even toxic medicinal materials, which were not placed in the medicine cabinet in the lobby outside.

There are more than 30 medicinal materials in total, divided into three medicinal materials. The medicinal properties, storage time and amount of each medicinal material need to be strictly controlled. It took less than half an hour before Ye Yuan prepared the first medicinal medicine.

When he walked back to the guest room, the guard had moved a large wooden barrel into the room. The barrel was filled with hot water, and there was a misty heat on the water surface.

Seeing Ye Yuan come back, the guard probably said that he was told by the young man that his face was not very good. When he saw Ye Yuan come in, he walked out of the door. Ye Yuan didn't care. As long as the semi-finished Gu worm in the young man's belly was fine, everything else was floating clouds. He was originally thinking that there was no good material for refining Gu worms, but he didn't expect that someone would hand him a pillow when he was sleepy. Even with Ye Yuan's personality, he couldn't help but be happy.

When the young man saw Ye Yuan coming, he smiled awkwardly and said, "I have always forgotten to introduce myself. Just go to Chu Yunfei, Dr. Ye will call Yunfei."

Ye Yuan nodded undeniably. Chu Yunfei took out a piece of fire-red jade from his arms, three fingers wide and one finger thick. It seemed like a flame was burning inside. He looked at Ye Yuan and said, "I can't find anything to boil water for a while. Can I use fire marble to heat water, Dr. Ye?"

Ye Yuan raised his eyebrows, smiled, and said, "It's better to have this thing. Take off your clothes and go into the water."

Chu Yunfei was free and easy. Since he was willing to let Ye Yuan treat him, he felt relieved and let Ye Yuan use it. Hearing this, he took off his clothes and jumped into the already warm water without saying a word.

Ye Yuan put the medicinal materials in his hand into the water one by one, and then said: "Let's inspire fire marble, slowly heat the water, stop when you feel the most comfortable, and keep the water temperature at that level."

Chu Yunfei rubbed the fire rock in his hand, put it in the water and felt that the fire rock was lit up. The water was heated rapidly, but it could not burn people. It was indeed very convenient, but this kind of thing was not affordable by ordinary people. A piece of fire rock with three fingers wide is at least 100 gold.

After Ye Yuan said that, he sat aside and closed his eyes to rest. It took him an entire hour to feel that it was almost done. Both Chu Yunfei and the insects in his body felt very comfortable.

At this time, Ye Yuan stood up, took out the second medicine he had prepared, rubbed it gently, and the dozens of medicines inside were pinched into pieces, then rubbed it a few times and merged it, walked to Chu Yunfei, and said, "If you take these medicines, it will be poisonous, and then you will stay in the water and not come out even if you feel uncomfortable! Otherwise, your efforts will be in vain!"

Chu Yunfei smiled and poured the main and secondary medicine into his mouth without saying a word, which made Ye Yuan look at him with admiration. After smiling, Ye Yuan said, "Remember clearly. No matter how uncomfortable it is, you cannot come out of the water, otherwise, the bug will drill into your head!"

After saying that, Ye Yuan gave Chu Yunfei a pulse, nodded and turned around and left. Judging from the situation, he could almost get the third medicine according to the situation.

In a cup of tea, Ye Yuan came back with the prepared medicine. In the bucket, Chu Yunfei was already sweating profusely, his face turned pale and pale, and there was a purple-green under his skin. He could tell at a glance that he had been poisoned.

Half an hour later, Chu Yunfei's consciousness became a little blurred. Ye Yuan still watched coldly, with a cold expression, and had no intention of detoxifying him. From time to time, a moving thing could be seen under his skin.

Putting three medicinal materials into the water, Ye Yuan rubbed the fire marble, and the heat emitted suddenly surged, the water temperature rose rapidly, and the whole house was filled with the smell of medicine. Chu Yunfei was already in a coma, and his skin turned translucent purple-blue, his lips turned purple and his face turned blue, and he was obviously about to die of poison.

Ye Yuan also frowned. The insects in Chu Yunfei's body only grew on their own. This kind of insect is the best to deal with, but it is also the most difficult to deal with, because it is considered to be something in Chu Yunfei's body, and there is almost no repulsion. Life is also derived from Chu Yunfei. It is difficult to drive away and can only be drawn out.

The best way is to make the environment inside Chu Yunfei's body worse and worse, while the environment outside the body is getting better and better. In contrast, the insects will spontaneously drill out, but at this moment, although the insects have been swimming under the skin from time to time, they still cannot drill out.

Suddenly, a finger knife appeared on Ye Yuan's hand, and quickly made seven or eight small holes on Chu Yunfei's shoulders, and blood began to penetrate into the water.

Outside the door, the guard who had been guarding him and couldn't come in seemed to smell the smell of blood, and suddenly broke into the door. At the same time, something like a worm poked out of the small head in the small wound on his left arm.
