Yin Qingyun and Yin Tianxing couldn't help much with this kind of thing, so they did chores and helped do some irrelevant things.

Zhang Zhenzhong also dismissed the people who were in charge of the Medicine Pavilion, the poison of the plague was too shocking to the world, and this matter was very important, and it could never be passed on.

After that, the three grandparents began to carry out research work in the medicine pavilion.

Zhang Tianhong carefully opened the cork of the jade bottle, and a faint smell gently hit his nose, which was very pungent.

The moment Zhang Hanlin and the three of them asked about this smell, they became more and more convinced, and the three people who had been soaking in the pile of medicinal herbs all year round were very sensitive to all kinds of medicinal smells and fragrances.

The toxin contained in the blood of this jade bottle alone is enough to be fatal, not to mention that Qin Yuefujun's whole body blood and even bone marrow are eroded by this poison, plus the traction of the medicine primer, once it erupts, it will really be weak.

The poison is a mixture of nine poisons.

However, the order of the configuration of the nine poisons, as well as the dosage and proportion, are not known, so the task of Zhang Hanlin and the three of them is to study and restore the original formula of the poison first, and finally configure the corresponding antidote prescription according to the poison prescription in a well-founded and targeted manner.

Zhang Hanlin has already prepared the silver needle and the test stone.

The test stone is also called the test poison stone, but it is not a stone, but a kind of fragrant agarwood, which has no value in itself, has no medicinal value, and cannot be a pillar of talent, which has been criticized by people.

But thousands of years ago, Qingxiang Agarwood was used as a test stone by the first generation of medical saint Zhang Ji, because Qingxiang Agarwood has the property of absorbing blood, and only absorbs blood!

Therefore, if the blood is dropped on the green incense agarwood, the blood can be absorbed, and what is finally contaminated and left on the surface is the toxins contained in the blood.

Since then, Qingxiang agarwood has become a special test stone, which has continued to this day.

In later generations, although some medical experts discovered several kinds of wood with blood-sucking properties that are indistinguishable from Qingxiang Agarwood, they still cannot replace the status of Qingxiang Agarwood in the medical world.

Up to now, the green incense agarwood has been priceless, fortunately, the ancestors of the Zhang family have left a lot of green incense agarwood, and it is generally not used, so it has been preserved from generation to generation.

Today, it finally came in handy.

The three of them looked at each other, and then decided to let the experienced Zhang Zhenzhong refine the toxin.

Zhang Zhenzhong took a half-inch-long and wide green incense agarwood and put it on the table in front of him.

The right hand twists a silver needle, the speed is like electricity, and the right hand moves, and the silver needle is submerged into the jade bottle.

Gently stir, and after two seconds, remove the silver needle and aim the tip of the needle downward towards the test stone.

"Click. ”

A drop of poisonous blood struck the test stone along the tip of the needle.

"Zizizizi. ”

The moment the blood came into contact with the green incense agarwood, it emitted a foul smell, three

The people frowned, but they all looked intently at the medicine test stone in front of Zhang Zhenzhong.

The blood quickly sank into the inside of the test stone, leaving a black stain on the surface.

"This is the toxin in the blood, Hanlin went to fetch a piece of silver paper. Zhang Tianhong looked at the puddle of black stains and said solemnly.

"Yes, Grandpa. Zhang Hanlin knew his grandfather's plan, got up and went to the three-layer cabinet on the left to get a piece of silver paper, and by the way, he also took a bone scraper from a tool box.

Looking at the two things handed over by Zhang Hanlin, Zhang Zhenzhong chuckled and said, "It's quite smart, I've got all the bone scrapers." ”

Zhang Hanlin didn't have the heart to argue with Zhang Zhenzhong, handed him two tools and then sat back in his seat.

Subsequently, Zhang Zhenzhong spread out the silver paper and used a bone scraper to gently scrape the black stains on the green incense agarwood on the silver paper.

After doing this, Zhang Zhenzhong began to dip the silver needle in the poisonous blood, and then dripped it on the green incense agarwood, and finally scraped the black stain on the silver paper.

The cycle goes on and on, and it's very boring.

But the three of them were full of energy, Zhang Hanlin saw it the most, he had mentioned this technique between the lines of medical skills, this was the first time he had really seen it.

Zhang Zhenzhong didn't dare to be distracted in the slightest, and this process lasted for an hour, consuming about one-fifth of the blood volume in the jade bottle.

Only then did Zhang Zhenzhong stop the movements in his hand and cover the jade bottle containing poisonous blood as soon as possible.

Then gently sort out the extracted toxins on the silver paper.

"That should be enough to study for a while. Zhang Zhenzhong said to the two.

Zhang Tianhong nodded and said, "Well, after studying these toxins first, Hanlin, you go and put the jade bottle in the item cabinet and be careful to break it." ”

"Got it. Zhang Hanlin responded, and then picked up the jade bottle and put it in the bottom layer of the three-story cabinet, in a wooden box, no one could enter this secret room, so no one except himself and others would be able to touch this jade bottle.

"Grandpa, what should I do next?"

Zhang Tianhong said: "I can't study it tonight, these toxins need to be wrapped in silver paper and exposed to the sun, so that the differences will be removed, leaving the taste of the toxins themselves, which is more conducive to research and determine the type of poison." ”

Zhang Zhenzhong also nodded and said: "That's right, we can only wait for tomorrow to be exposed to the sun for a day, and when the smell is gone, we can start research tomorrow night." ”

Zhang Hanlin thought for a while and said: "That's fine, you can also prepare more research tools during the day tomorrow, so be it for today, and start research tomorrow night." ”

"Well, Zhenzhong, you wrap these toxins in silver paper first, put them away, and tomorrow the sun rises and take them out. ”

"Yes, father. ”

After instructing Zhang Zhenzhong, Zhang Tianhong looked at Zhang Hanlin and said, "Hanlin, it's okay now, are you going to cultivate tonight?"

Zhang Hanlin shook his head and said, "No, grandpa, don't be in a hurry when you cultivate, I'm going to study the books on poison in the family medicine pavilion tonight." ”

"Don't you hate those books the most?" Mr. Zhang quipped.

"What about hating? It's about the survival of hundreds of people. Zhang Hanlin sighed, natural disasters can be avoided, ** difficult to avoid.

Zhang Zhenzhong and Zhang Tianhong looked at each other and smiled.

"Since you want to read it, then you can go, you are also familiar with the various books in the medicine pavilion. Zhang Tianhong said with a smile.

"Grandpa, aren't you curious about the [Yin and Yang Technique] I cultivated?" Zhang Hanlin was very curious.

[Yin Yang Jue] is also a relatively long-term heirloom in the Zhang family, but because of its strange phenomenon, all the ancestors who cultivated the [Yin Yang Jue] basically returned to the mortal in the end, except for Zhang Ji's ancestor who reached the peak of the six realms of martial arts, the realm of a half-step grandmaster.

You must know that the [Yin and Yang Jue] created by Zhang Ji's ancestor has a superior grade.

Although his father gave him the [Yin and Yang Jue] to practice, it is very likely that he also let himself die to practice martial arts, or one day he will return to the world like many ancestors, and then he will be able to concentrate on carrying forward the Zhang family's medical skills.

But after practicing the [Yin and Yang Technique] by himself, my father and grandfather didn't seem to be very surprised!

Zhang Tianhong and Zhang Zhenzhong laughed and said, "Hanlin, in fact, the ancestors have already told the descendants of the secret of this [Yin and Yang Formula]. ”

Zhang Hanlin's eyes widened and he said in surprise: "Grandpa, father, do you know?"

"Well, according to the third-generation medical saint Zhang Lingming's codex, it shows that the [Yin and Yang Jue] created by Zhang Ji's ancestors is not so much a superior exercise, but a superb minor exercise, and the true qi of those who cultivate the [Yin and Yang Jue] is of great help to other people's martial arts, and when Zhang Ji's ancestor created the exercises, he mixed medical skills, the Yin and Yang Avenue of Heaven and Earth, and the righteousness of the three of heaven, earth and man, so those who have cultivated the [Yin and Yang Jue] also have a strong healing effect on their true qi. Zhang Tianhong recalled.

"I'm sure you've discovered these two secrets. ”

Zhang Hanlin nodded and said, "Well, Tianxing was injured that day, and I discovered the secret of the [Yin and Yang Formula]. ”

Zhang Zhenzhong looked at Zhang Hanlin without a trace of disappointment, disgust, or some other emotion.

Zhang Zhenzhong asked: "Hanlin, [Yin and Yang Jue] was called a minor practice by Zhang Lingming's ancestors, and it is precisely because its effect on others is more obvious and powerful than his own, and the word furnace ding is most suitable for use here in medical terms, which is called altruism. Aren't you worried?"

Zhang Hanlin pouted indifferently and said, "What am I worried about? I knew the secret of the [Yin and Yang Formula] two days ago. Things are dead, people are alive, and the key lies in how I use it. I don't need to use my true qi to save people, what is there to worry about. ”
