The poison Shi Kang used at the beginning was a kind of mixed poison, which had little influence on each other and could not kill people.

Because it was spread all over the city at that time, and there were many innocent people, it was impossible to include them all and kill them all.

In the later stage, when the Demon King's army retreated to their camp, it would logically be the best time to kill them with poison.

There are not many outsiders here anymore, so it is the most appropriate time to use poison.

But deadly poison is not so easy to make.

Although Shi Kang could make poison with enough toxicity, it would either require blood to seal the throat, or it would need to be drank in the stomach to be effective.

Although there are some that can cause poisoning and death if spread in the air, those herbs are extremely rare and difficult to obtain.

Shi Kang's medicine shop does not have any reserves for this, nor can it be mixed with other herbs.

More importantly, if the distance is not far, if it is blown by the wind, the effect will be greatly lost.

So what he used was a method of stacking poisons. By continuously accumulating the level of poisons, the effect would be deepened and eventually kill people.

In the past few days, soldiers from the Demon King's army have been dying in the military camp, mostly because of this method.

It was precisely because people started to die and the talk of "plague" that made them so panicked.

But there was another completely new change in the medicinal residue collected by Shi Kang this time.

The poison knowledge that Shi Kang obtained was only Doctor Ning's own medical skills. Even if he read and understood it thoroughly, it would only reach the level of Doctor Ning himself.

So he couldn't turn existing herbs into deadly, widespread poisons.

However, the medicinal properties of this medicine residue can greatly enhance the effect of his poison, making it more hidden and lethal.

Yes, hidden.

Shi Kang reflects each other's medicinal properties and then reacts to them, and can quickly draw a conclusion.

The medicinal effect of the decoction of this medicine residue is nothing other than absorbing the medicinal effect of the poison that Shi Kang put in, purifying and condensing it.

Therefore, although drinking this decoction may seem to relieve the "plague", in fact, it is keeping the poison in the body, and after waiting for a period of time, it will lead to sudden death.

When he got here, Shi Kang couldn't help but gasp, this man was so powerful.

The other party's medical skills far surpassed his own. Not only was he able to use his current form to perfect his own poison, but he was also ruthless enough to kill all the Demon King's army in one fell swoop.

Who could have such means? Shi Kang thought about it, and the image of the white-haired military doctor suddenly appeared.

"is it him?"

With some doubts, Shi Kang was ready to find out more.

On the other side, in the camp in the east of the city, the people of the Demon King's Army were celebrating that the plague was gone.

While they were praising the efficacy of Bai Langzhong's medicine, they were ready to carry out the order to massacre the city again.

Especially after a few days of frightening, I hope to use a killing to soothe my heart.

However, Bai Langzhong stopped them: "Although my decoction can cure the plague, it has little effect on those seriously ill patients."

"Those people gathered together may have become a purgatory. If you go there at this time, wouldn't you be taking yourselves there as well?"

"I might be infected with the plague again, and even the decoction will have no effect."

Bai Langzhong had to listen to what he said. Although people in the Demon King's Army didn't think much of him before, this time he saved everyone and got their approval, so after discussing it with each other, they continued to stay in the camp.

Inside.

Li Jie was also very excited about the verification of the efficacy of the medicine in Chengdong Daying.

Although he had been eating, drinking and having fun in the county government these past few days, it was still suffering for a person like him.

Since the decoction is effective, he doesn't have to worry about getting sick and can come out without hesitation.

"General, this decoction can not only cure the plague, but drinking it in advance can also prevent infection."

Bai Langzhong came in with a pot of soup and said to Li Jie, "If the general wants to go out, it is best to drink a bowl first."

As he spoke, he found several bowls, poured the decoction into them, and drank two bowls himself first.

"okay!"

Seeing Bai Langzhong drink the decoction completely, Li Jie showed a happy smile on his face, "Now let's go to Chengdong Camp to talk to my brothers."

After saying this, he drank up the soup in front of him in one gulp and burst into laughter.

Soon, bursts of cheers came from the camp in the east of the city, and everyone showed a warm welcome to Li Jie's arrival.

Of course, there is no need to study in detail what it actually is.

Anyway, after Li Jie officially appeared in front of everyone, the morale of the Demon King's army had indeed improved a lot. When Shi Kang met them, he could clearly detect that their spirit was different from before.

"But this situation can't last long."

Shi Kang hid at home and prepared the last packet of medicinal powder, "Today is the last feast."

The death of a few soldiers did not frighten the soldiers of the Demon King's Army, and with the auxiliary "curative effect" of the decoction, their morale was even higher.

But after today, the sudden death of a large number of people will prompt them to have the largest encampment and roar, and then leave the city in fear.

"hope everything is fine."

80 points of luck are enough to elevate Shi Kang's strength to a new level.

If an accident occurs, he will suffer a huge loss.

late at night.

Shi Kang put on black clothes, took advantage of the night and when no one was around, climbed onto the wall in the east of the city, looked at the dim campfire in the camp not far away, and began to light the powder he carried.

The dark sparks extinguished in an instant, leaving no trace of fire.

Wisps of smoke began to move slowly forward, gradually spreading throughout the entire east camp.

Looking from the top of the city wall, one can vaguely see a large mass of mist, gradually enveloping the camp in the east of the city and shrouding his body.

Several soldiers on guard were talking quietly, and when they were happy, they even laughed in a low voice, without any reaction to anything around them.

Occasionally, patrols would pass by, but they never had any reaction, and they couldn't sense that anyone was doing something terrible here.

The night passed so quietly.

At dawn, a shrill scream rang out from the camp in the east of the city.

The sleeping camp suddenly woke up, and many soldiers of the Demon King's Army let out horrified shouts.

What appeared in front of them were large areas of dead bodies.

Their bodies were densely covered with bright red swellings, like those seriously ill plague patients.

In the camp east of the city with 2,000 people, three or four floors died overnight.
