A thousand-year-old family begins with one fighting against ten thousand.

"Quickly! Please come in!"

As if experiencing a sudden surge of energy before death, Li Longji was able to sit up in bed.

After Prince An, Wei Xun, entered the capital, he was received by people sent by Li Longji and brought to the palace.

Travel-worn Wei Xun arrived at the Imperial Physician's Office without even having a sip of water to examine the poison he had obtained from An Lushan.

I also looked at the recent research reports from the Imperial Medical Bureau and the components they analyzed.

"I'll say it, you write it down."

Wei Xun spoke to the imperial physician.

The imperial physician quickly picked up a pen, spread out a piece of paper, and prepared to make careful notes, his eyes filled with gratitude.

Many imperial physicians gathered around, listening attentively. To receive guidance from Prince An was a rare opportunity.

In particular, Prince An saved their lives. If Wei Xun hadn't arrived in time, they would probably all be beheaded by now.

Wei Xun ignored the gratitude of the imperial physicians, picked up some poison powder with his fingers, and sniffed it.

"Litharge, Realgar, Orpiment, Copper sulfate, Ferrous sulfate, Halloysite, Tin powder, Aconitum carmichaelii, Aconitum carmichaelii root, Aconitum kusnezoffii, Datura stramonium, Gelsemium elegans, Hemlock, Veratrum nigrum, Strychnos nux-vomica, Croton tiglium, Hedyotis diffusa, Oleander, Xanthium sibiricum, Euphorbia kansui, Euphorbia pekinensis, Daphne genkwa, Phytolacca acinosa, Podophyllum hexandrum..."

As Wei Xun sniffed the powder, he spat out one poisonous ingredient after another.

Most of them overlapped with the poison components tested by the imperial physicians, but there were still a dozen or so that were different.

As he finished speaking, Wei Xun frowned. He smelled two different scents, but had no recollection of them at all.

This is troublesome.

He had already heard from the imperial physician about Li Longji's physical condition, and there was not enough time for him to explore the medicinal properties of these two ingredients through various methods.

"Note this down; there are two more unknown medications."

After Wei Xun finished speaking, he took out paper and pen from the side and began to write down the names of the medicinal herbs one by one.

"Ginseng, honeysuckle, mung beans, duck blood, Smilax glabra, sesame oil, honey, kelp, Saposhnikovia divaricata, Angelica dahurica, rice vinegar, licorice, wheat bran, red ochre, honey, maltose, mung beans, strong tea, fresh water spinach, ground broth, scallion, gardenia, mung beans, Coptis chinensis, licorice, ginger, Isatis indigotica, jujube, dried ginger, cinnamon twig, Sophora flavescens, Platycodon grandiflorus, Akebia quinata, mulberry leaf, fresh reed rhizome, egg white, licorice, Rehmannia glutinosa."

"Let's go to the Zichen Palace to check on His Majesty's health."

"Have someone send all the medicines listed on this prescription to the Zichen Palace."

Numerous imperial physicians hurriedly followed behind Wei Xun, carrying various medicines. The chief imperial physician personally carried Wei Xun's medicine chest.

"Prince An, you've arrived."

Crown Prince Li Heng hurriedly came forward. When Li Longji received the news that Wei Xun had arrived in Luoyang, he had a moment of lucidity before losing consciousness, but he quickly fell into a coma again.

For the past two days, Crown Prince Li Heng has been serving the Emperor, showing the utmost filial piety.

Behind the Crown Prince, Li Bai and other important court officials rushed over as soon as they learned that Prince An had entered the palace.

"Greetings, Prince An."

"Greetings, Your Highness."

Prince An, Wei Xun, bowed slightly.

Crown Prince Li Heng quickly stepped aside, took two steps forward, and grabbed Wei Xun's hand, saying, "Prince An, please come quickly. Father has been waiting for a long time."

Wei Xun nodded to everyone, then followed Li Heng to Li Longji's bedside. Despite his white hair and advanced age of eighty-six, Wei Xun was in excellent health. Many imperial physicians could not keep up with his speed, and it was only then that they hurriedly arrived at the Zichen Palace, panting heavily.

Wei Xun reached out and pried open Li Longji's eyelids, then pinched open Li Longji's mouth and looked at his tongue.

He stroked his beard, already having made his decision.

Finally, Wei Xun reached out and took Li Longji's pulse in his left and right hands, nodded slightly, and put Li Longji's hands back under the covers.

"Your Highness, I have two prescriptions, each with its own advantages and disadvantages."

"His Majesty is currently unconscious; we request Your Highness to make the decision."

"Please speak, Prince An."

Li Heng said calmly.

Wei Xun nodded slightly. It seemed that Li Bai was quite skilled at teaching his disciples, and Li Heng's teaching was quite good.

"His Majesty has already been poisoned to the heart. There are still two components in the poison. It will take another two days to determine its effects, but His Majesty's body may not be able to wait that long."

"I have two options. The first is to use strong medicine to completely expel the toxins from Your Majesty's body in one fell swoop."

"The advantage of this method is that His Majesty will be somewhat weak for a period of time, but will still be able to function normally."

"The downside is that His Majesty's lifespan may not be that long. After all, the poison has already invaded his heart meridian. To expel it completely quickly, the medicine needs to be extremely potent, which would cause great damage to his body."

"His Majesty's body has already been riddled with holes by the poison. With such a strong dose, he may only have a year left to live."

Wei Xun stroked his beard. Birth, old age, sickness, and death are inevitable for everyone, from princes to nobles. As a physician, he had long been able to accept it with equanimity.

Even if the emperor was the one he had given the lifespan notice to.

"No, no, that won't do. Only one year to live? How can that be? Prince An, what's the second method?"

The crown prince quickly asked.

Wei Xun glanced subtly into the Crown Prince's eyes, which held only worry for Li Longji. He nodded silently to himself while greeting him as usual.

"The second method is to use slow-acting drugs to gradually suppress the toxicity and prolong the life."

"If this method is adopted, His Majesty will likely have another 10 years to live."

"This one is good, let's choose this one."

Crown Prince Li Heng said impatiently.

Wei Xun shook his head. "Your Highness hasn't finished speaking yet."

"The drawback of this method is that the toxins will suppress and disturb His Majesty's body, causing him to suffer from excruciating pain all over his body every day."

"this……"

Li Heng's expression also turned somewhat grim. Even Prince An had said so, so there was no doubt that there were only these two options.

It's unlikely that anyone else could come up with a different solution.

Choosing the second option would allow his father to live for several more years, but he would have to suffer from illness constantly.

If the first option is chosen, his father will feel better, but he will be physically weak and will not live long.

As a son, he found it difficult to accept either of these situations.

The many ministers standing nearby remained silent.

None of them should interfere in this matter.

"I choose the second option."

Li Longji's weak voice rang in their ears.

"Father, you're awake."

Li Heng quickly came to Li Longji's side, took Li Longji's hand, and his eyes were full of concern for his father.

"Your subject pays respects to Your Majesty."

Wei Xun bowed to Li Longji.

"Prince An, there's no need for such formalities. I've chosen the second method. Please prepare the medicine."

When Li Longji uttered these words, he used almost all his strength, and after speaking, he was barely breathing and on the verge of death.

He was the emperor of the world, he possessed the wealth of the four seas, he had not enjoyed it enough, and he did not want to die!

"Your Majesty need not speak further, I already understand."

Wei Xun nodded. The medicinal herbs he had prepared had already been delivered.

He selected some of them, opened his medicine box, took out some medicinal herbs, and began to prepare an antidote for Li Longji on the spot.
