When he came to the village, Zhao Qiankun saw all the infected villagers in the village. After treating several serious ills who were terminally ill and could die at any time, he began to study this bacteria.

After seeing Zhao Gan's ability to rejuvenate, the villagers admired him more and followed Lao Zhao Yan's advice. Especially after hearing that he wanted to prepare special medicines for the plague, the villagers did everything possible to meet his requirements and ensure that Zhao Qiankun's research went smoothly.

Of course, this so-called guarantee is basically a joke in Zhao Qiankun's eyes, except for providing experimental materials. In this relatively backward world of technology, there are no laboratories, no beakers and test tubes, no refrigeration equipment and centrifuges, and it is even more impossible to ensure that the bacterial flora will not be contaminated by impurities in the air. Even if you find a doctor of medicine here, you will be helpless in the face of this harsh experimental environment...

But Zhao Qiankun is not a doctor of medicine, so he can't use those fancy equipment he gives him.

But he knows the magic of the plague and knows how to use the methods of this world to create an antidote!

Plague magic is essentially a magic that controls microorganisms. However, this world does not have a microscope and lacks a basic understanding of the microscopic world. Therefore, the plague mage does not know what his power means. He can rely on macro observations to understand his magic effects, and explore and move forward in half-mapping and half-testing.

But now, under Zhao Qiankun's suggestion on the principle of microscope, the genius mage Klin Yi invented the microscope technology. With this microscope, Zhao Qiankun could indeed see which viruses and bacteria he had obtained, so in the true sense, he began to study the plague magic in depth!

This process is convenient and interesting. Just imagine that bacteria are as gentle and obedient as dogs, so that they can be ordered by you. It is easy to walk in line in a row, and can even hybridize and combine different species to create a brand new breed! With the dual combination of magic and technology, various slutty operations that Earth scientists dare not even imagine have been realized in the hands of Zhao Qiankun!

And this also made him quickly discover the weaknesses of these bacteria!

This was inspired by the villagers, and the elders in the village brought him a herb. According to them, when the epidemic was the most severe, they relied on this herb to support it.

"Although it cannot be cured, it can control the spread of the plague. It is not so painful to extend the lifespan of infected people. Healthy people can also reduce the chance of getting infected..."

Zhao Qiankun picked up the herbs, mashed them according to the villagers' instructions, added vinegar and wood ash to boil them. After filtering, he observed them and found that there was indeed some ingredient in the herb soup, which could reduce the activity of the bacteria.

"How did you find out?" Zhao Qiankun curiously said: "Is this herb very common?"

The elder shook his head: "This is a herb specialized in the chaotic forest. There is no near the village. It was first brought by Lord Haierluo and the Joan of Arc, the heart of the lion. After we found it effective, we sent a mission to the Adventurer Guild. After that, the herbs in the village were provided by the Adventurer Guild..." The elder sighed: "To put it bluntly, our village is relatively close to the chaotic forest, and it is convenient to obtain herbs... The villages and towns deep in the empire are difficult. We often encounter them coming from hundreds of kilometers away to buy herbs, which is so pitiful..."

"Take it from Haierluo and Joan of Arc?" Zhao Qiankun narrowed his eyes, then put the herbs in his mouth and chewed them directly.

"Don't..." The elder hurriedly dissuaded: "This herb cannot be eaten raw. It is poisonous and will make people numb!"

Zhao Qiankun waved his hand, and saw him chewing it carefully, slowly feeling the numbness spread throughout his mouth and then spread to his throat and neck... However, Zhao Qiankun was indifferent and even swallowed the herb after chewing it.

As the herbs entered the digestive tract, the numbness spread throughout the body from the inside to the outside. If it were an ordinary person, he would have been paralyzed and collapsed to the ground now. However, the Vajra skeleton in Zhao Qiankun's body supported him to continue moving.

The herbs that entered his body did not all pass through the digestive tract and turned into excrement. Some of them were pulled by a mysterious force and penetrated into Zhao Qiankun's sternum and absorbed by the seeds of the world tree in his chest!

Relying on the power of the world tree seeds, Zhao Qiankun's body's numbness quickly eased and he quickly recovered. Then he stretched out his fingers, and green light shone out of his fingertips, and a tender grass was grown, exactly the same as the herb he had just eaten!

Seeing this scene, the elder almost knelt on the ground. If it can cure the plague and explain it with exquisite life magic, then this technique of fingertip grass can only be described as miracles!

The elder is the most knowledgeable person in the village. At first, he did not believe in the lies of the gods and envoys that the villagers boasted about. But now, he is really impressed. This is not the gods, but the gods are simply descending to earth!

Zhao Qiankun ignored the elder's kneeling and directly used the new herbs at his fingertips to test it, trying to extract the ingredients!

Although the equipment is simple, it has microscopic magic monitoring, plague magic escort, and Zhao Qiankun's experimental level is probably beyond the reach of the cutting-edge laboratories on Earth. Under his operation, the ingredients in the herbs were perfectly separated, mixed with bacteria samples, and the experiment began.

The herb targets bacteria in fact are the toxins that paralyze the human body. This toxin can indeed inhibit the activity of bacteria at first, but it is difficult to really kill bacteria. After the ingredients are exhausted, the bacteria will still survive and will continue to damage the human body.

It seems that the toxicity is not strong enough...

Zhao Qiankun began to try to adjust the herbal ingredients. With the power of the plague magic and the world tree, he gave birth to more toxic herbs. After purification, he tried again...

However, for Zhao Qiankun, who lacks theoretical knowledge, this kind of experiment is still a bit of a chance...

For example, after he extracted herbs that could completely kill germs for the first time, he immediately found a villager who was infected to test. The result was that after drinking the medicine soup, the villagers were poisoned to death before they could kill all the germs in his body...

Of course, the so-called death here is just a loss of breathing and heartbeat, and a loss of vital signs on the surface. In fact, there is still a little difference from real brain death. Under Zhao Qiankun's red fruit, the villager was successfully rescued. After the toxins in his body were exhausted by the lifeline that the red fruit forced to pull, this guy was out of danger of life.
