Datang: Ten Years of Proton, Leading an Army of Millions to Return

Don't think that old demon Cheng doesn't know that the King of Goguryeo is a very shrewd man.

Can the treatment of smallpox empty his treasury? Old Cheng doesn't believe it. Maybe there are still many good things hidden!
Want to cheat him? No way!
Although the King of Goguryeo borrowed his life, the treasury's money was also his life! So the King of Goguryeo hesitated between the two.

But the old demon was not in a hurry. If Li Kuan didn't come out, he couldn't make any great contribution to the disease.

Anyway, he had plenty of time to waste with the King of Goguryeo.

"Well, well, well, please take me to the Li residence."

But the King of Goguryeo thought carefully about what Cheng Lao Yaojing said, and realized that one bag should not be able to hold all his treasures.

So he agreed to the request of the old demon Cheng.

"Okay! You have to give me a written receipt before I come back to treat him. You two! Pick him up and go back home!"

When Cheng the old demon saw that the King of Goguryeo had agreed to him, he immediately smiled and he did not dare to go back on his word.

Otherwise! Hum…

After receiving the order, the two soldiers dared not say anything.

They carried the King of Goguryeo to Li Kuan's mansion.

What the King of Goguryeo did not expect was that the bag that the old demon Cheng would carry in the future would be a huge sack filled with grass and grain.

After being attacked by the demon, the King of Goguryeo lost even his last chance to turn things around after being robbed so badly in the future.

~

Inside the Li Mansion.

"Congratulations, mission accomplished."

"Get the mysterious reward: antiviral oral liquid formula! It can be used to treat smallpox."

The mission was finally completed, but Li Kuan was extremely anxious.

But Li Kuan was very happy about this mysterious reward, as it was just enough to solve his current urgent needs.

But I don't know how effective the medicine is and what side effects it has. If something bad happens, it will probably be beyond my control.

Li Kuan didn't want to take this risk! He had to find someone to try the medicine in this system before it could be prepared for widespread use.

Li Kuan immediately thought of the King of Goguryeo who came to ask for help two days ago. He could be used to test the medicine.

It happened so quickly that it happened just as I wished.

"Li Kuan! Li Kuan! I'm back!"

Before the old witch even entered the room, her loud voice had already reached Li Kuan's ears.

"You two, take him outside first. I will go in and talk to Li Kuan, then bring him in!"

Old Demon Cheng gave orders to two soldiers, then glanced at the King of Goguryeo, turned around and pushed open Li Kuan's door.

"You've been resting for so long, have you recovered from your illness? Can't you stretch your muscles? The people outside are almost dying!"

After the old demon Cheng came in, he didn't rush to talk about the King of Goguryeo, but instead started to criticize Li Kuan.

"What nonsense are you talking about! King Goguryeo, have you come today?"

Li Kuan was a little anxious at the moment, but he didn't want to argue with the old witch. After all, he was still waiting for the King of Goguryeo to come and try the medicine!
"Oh, we are so in tune with each other right now! As for the person, I found him for you on the road."

Old Demon Cheng was a little surprised. Why would Li Kuan take the initiative to talk about the matter of the King of Goguryeo?

Li Kuan was even more surprised. Not to mention how much this old devil disliked the King of Goguryeo in the past, Li Kuan also knew about his taboo against smallpox.

Now that he has taken the initiative to bring the King of Goguryeo to his own house, there must be some hidden agenda.

"Why? Why are you being so kind today? Did he do you some favor?"

Li Kuan was relieved when he heard that the old witch had brought the King of Goguryeo here. He drank a sip of tea and started to chat with the old witch.

"What are you talking about? Can't I be a good person again? Save the dying and the wounded?"

"At least saving a life is better than building a seven-story pagoda!"

It seemed that the old demon Cheng had no intention of telling the story of how he robbed the King of Goguryeo.

"Oh, you are quite educated. Where did you learn these words? I would believe you if you saved others, but what about the King of Goguryeo? Would you bring him to my house if there was no benefit? Tell me, don't hide it."

Li Kuancai didn't believe the old witch Cheng's words.

Old demon Cheng was somewhat happy and actually thought that Li Kuan was praising him for his progress.

He then told them about the robbery of the Goguryeo treasury.

"He just gave me a written agreement and asked me to take a sack and go to the Goguryeo treasury for a visit!"

After saying this, Old Demon Cheng scratched his head embarrassedly, then started to laugh.

Li Kuan had already guessed that the old witch had received some benefits from the King of Goguryeo, but he did not expect that the old witch would directly take advantage of the other party's treasury.

But now the most important thing is to test the medicine. There is nothing wrong with the old witch's behavior, so Li Kuan didn't say anything else.

"Okay, since you've received the money, just bring him in. I've just developed a new drug to fight smallpox, and I'm in need of someone to test it on."

Old Demon Cheng didn't expect that Li Kuan would be so straightforward. He instantly felt that he had made a fortune.

"Okay, I'll bring the person in right away!"

Old Demon Cheng was about to ask someone to bring the King of Goguryeo in, but then he thought something was wrong.

"Is it possible that you have been thinking about this these days? Why didn't you tell me earlier?"

The old witch felt a little guilty for a moment, it turned out that he had wronged Li Kuan.

"It hasn't been successfully developed yet. I'm afraid you'll be disappointed. It's still in the drug testing stage."

"Hurry up and bring the person in. I've heard about the condition outside, and we can't wait any longer."

Li Kuan gave a perfunctory explanation and fooled the old witch, asking him to bring the King of Goguryeo in to try the medicine first.

"OK!"

After saying this, the old demon Cheng opened Li Kuan's door and yelled outside.

"You two, bring him in!"

Two soldiers brought the sick King of Goguryeo to Li Kuan. Li Kuan frowned. He did not expect that his condition would deteriorate so quickly within two days.

"Come on, drink it."

Li Kuan handed the medicine that had just been prepared by the system to the King of Goguryeo and looked at him with anticipation.

When the King of Goguryeo saw Li Kuan's malicious look, he began to doubt the black medicine in front of him.

"Is there anything wrong with this medicine?"

The King of Goguryeo took it and asked tentatively.

"Drink it or not, if we want to kill you, do we have to poison you? We would have killed you with a knife back in the military camp!"

When the old demon Cheng saw the King of Goguryeo's ignorant look, he couldn't help but say a few words.

"Hey! Don't be impulsive, Lao Cheng."

"This is indeed a newly developed drug. Although it may have some adverse side effects, it is indeed very effective against smallpox. If you don't believe me, just drink it."

Li Kuan raised his hand to stop the old demon's next move, and instead patiently explained to the King of Goguryeo.

The King of Goguryeo hesitated for a while, but still drank the medicine in his hand. When Li Kuan saw the King of Goguryeo drink the medicine, he immediately stared at the King of Goguryeo, fearing that he would miss a detail.

Seeing that Li Kuan was so serious, Old Demon Cheng did not dare to be vague and stared straight at the King of Goguryeo.

As Li Kuan expected, this medicine did have serious side effects.

After taking the medicine, the King of Goguryeo immediately had an extremely strong reaction.

"Ah...ah! What kind of medicine is this! Why does my body feel like it was crushed by a carriage?"

The King of Goguryeo wailed in pain on the ground, but soon he was in so much pain that he couldn't speak. He kept hitting his head with his hands and even bit his arms to relieve the pain.

The self-mutilation of the King of Goguryeo seemed to have caused him to bite the herpes on his body. It was a disgusting scene.

Even the old goblin who was watching aside had a hint of pity in his eyes when he looked at the King of Goguryeo in front of him.

"Li Kuan, is there really nothing wrong with your medicine?"

The old demon Cheng couldn't bear it any longer, so he squinted his eyes and grinned at the King of Goguryeo with disgust and asked.

But Li Kuan, the same thing applies.

"It's okay. You won't die. It's just a side effect."

Indeed, it is impossible for the medicine given by the system to be ineffective. At most, it will be like the current King of Goguryeo, with greater side effects.

"But why is this broken system so unreliable? Can't the rewards be better?"

Li Kuan couldn't help but complain.

"Hmm? What are you mumbling about?"

The old goblin thought Li Kuan was talking about some potion, and couldn't help but interrupt.

"It's okay, I just..."

"What the hell! Why did this guy faint? Is he dead?"

Before Li Kuan could finish his words, the old demon Cheng's attention was attracted by the King of Goguryeo.

The pleasure came and went quickly, and the King of Goguryeo soon fainted.

He fell to the ground in Li Kuan's room.

Li Kuan couldn't help but twitch the corners of his mouth.

Are the side effects that serious?
Is it so unreliable?
"It's okay, just wait a little longer, you won't die."

Li Kuan still told the old witch firmly that there was nothing wrong with the medicine, it just had some serious side effects.

Old Demon Cheng looked at Li Kuan, then at the King of Goguryeo, and frowned.

Now, apart from trusting Li Kuan, I can’t think of any better solution.

Time passed minute by minute, but the King of Goguryeo still showed no signs of waking up, and the old demon Cheng became a little anxious.

"Li Kuan, why hasn't he woken up yet?"

Li Kuan glanced at the old demon Cheng, and didn't know why the old demon was so anxious. He was the one who made the medicine, but before he was even anxious, the old demon was already anxious.

"It's okay, let's wait...wait a little longer."

Before Li Kuan could finish his words, the old demon Cheng brought a plate of cold water from somewhere and poured it over the King of Goguryeo.

"Cough. Cough cough..."

This plate of cold water seems to have some miraculous effect. Once it is poured on,
The King of Goguryeo curled up his body.

The King of Goguryeo seemed to show some signs of waking up, and Li Kuan finally breathed a sigh of relief.

"Carry him down, find a room in the mansion to keep him there first, and then observe if there are any sequelae later."
Li Kuan said to the old witch that this was a plan to take in the King of Goguryeo in Li’s mansion.

Although Old Demon Cheng was a little unhappy, he didn't say anything.

"What about this medicine? Can we use it to save lives? I followed them around the city a few times and I feel that this matter can't be delayed any longer."

Compared with the King of Goguryeo, the old demon was more concerned about the people outside whose lives were uncertain.

"No, you have seen the side effects of this drug if it is widely used."

"If you don't know, you might think I, Li Kuan, poisoned them."

Li Kuan rejected the old goblin's idea, saying that the medicine had not yet been perfected and must not be put into use.

It’s okay for strong young people, but if it’s weak children who can’t withstand the side effects, who knows how many people will die!

"Please help me find Sun Simiao and his group. I need their help."

"Those quacks? What's their use?
After seeing the current situation of the plague in the city, Old Demon Cheng's only idea of ​​that group of people was that they were just eating for free.

"Don't be unreasonable. Go and do the job for me first. By the way, let's talk about the bet we made last time..."

Li Kuan hintedly reminded the old demon of the bet that Niudou and the others had made before.

It was agreed that if he cured the soldiers, the old demon would be his younger brother for a year.

"Those guys of Sun Simiao are really bad! I will call them over right away. Just wait for me here."

When the old demon heard Li Kuan mention this incident, he immediately slipped away.

Just when the people outside the city were at a loss, the old demon Cheng brought them good news.

"Li Kuan asked you to come to the Li Mansion, saying that he has something to discuss with you."

Old demon Cheng was panting and gave it to Sun Simiao and others.

"Your Majesty, have you found a cure for smallpox? I'll be there right away."

The group of old men were worried about Li Kuan and ignored their matter, but when they heard that Li Kuan was looking for them, they were so happy that they wished they could grow wings and fly to him immediately.

"The medicine seems to have been developed. I'm not quite sure, but I heard that the side effects seem to be quite serious. Li Kuan doesn't plan to use it on a large scale."

"The King of Goguryeo has already tried the medicine. He had a severe reaction, but he survived."

"It seems that I asked you to go there to discuss countermeasures."

Old Demon Cheng told Sun Simiao and others everything he knew as a precaution.

"Understood. We will go to Li's residence immediately."

After hearing this, Sun Simiao took the old men, packed up his charity box, and headed to Li's house in a hurry.

……

Inside the Li Mansion.

"You're here? Please take a seat. This is an antiviral oral liquid I developed these days to fight smallpox."

Li Kuan was also very happy to see Sun Simiao and others. He immediately took out the medicine developed by the system and began to talk about the medicine with the imperial doctors.

"I have tried this medicine on the King of Goguryeo. It is completely safe. The King of Goguryeo is now in a much better condition."

After saying this, Li Kuan ordered two soldiers to push out the King of Goguryeo, who had just survived.

At this moment, the dense blisters on the face of the King of Goguryeo had dried up and he began to stutter. The fever had gradually subsided, and his physical strength had recovered a lot. These were signs of improvement from smallpox.
