I don't know how many materials need to be used, Chang Shuang has dried and burned a plate of fruit shells, which can be more or less.

After dehydration, the husks are charcoal into small grains, and then put into a porcelain beaker and boiled with salted water.

There is no way, Changshuang can only simply use salt instead of hydrochloric acid, and there is no hydrochloric acid here, and the production of hydrochloric acid is too troublesome.

After boiling, the water turns pale yellow, pour out the water and add salt to boil, and so on several times to remove the impurities of the husk charcoal.

After cooling, it is filtered several times to finally form the husk activated carbon. In the absence of modern industrial tools, it can only be made in this way.

Busy until the evening, Chang Shuang finally made the medicine, and her medicine has the ability to absorb garbage substances and suck out the poison from the poisoned person's body.

"Doctor Chang, dinner is ready, let's take a rest and eat." Mo Fei took care of Chang Shuang, helped her with medicine, and did not delay people to eat.

"It's getting dark, I'll eat later."

Chang Shuang was not in a hurry to eat, she went to find Ehebai first, and she left early if the matter was settled.

"Drink this." Chang Shuang gave a glass of black water to Ehebai to drink.

"What is this?" Ehebai's face is not good, is this medicine? It's dirty water.

"It's medicine, you drink it." After a busy day, Chang Shuang was tired and didn't bother to explain in detail.

No matter how you look at it, it's all dirty water, Ehebai stared at her and hesitated not to drink it.

Chang Shuang and Ehebai stared at him with wide eyes, looked at him defiantly, and forced him to drink with their eyes. It's something she's worked hard to make.

E Hebai refused this cup of black water both physically and psychologically, she wouldn't be to retaliate against him in the name of treatment, right?

Ji Ruyan saw that the two were at a stalemate again, and hurriedly persuaded: "Your Highness, this is the medicine that Dr. Chang worked hard to make, you better drink it quickly!" ”

Ji Ruyan watched the whole process, watching Chang Shuang carefully make the black gadgets, he didn't think she was just trying to trick people.

E Hebai glanced at the person who didn't care about him, and then reluctantly poured it down, and he didn't taste any taste, but he still felt an unacceptable taste in his mouth.

E Hebai looked at Chang Shuang, what was she going to do now.

Chang Shuang grinned: "Your Highness is good, drink it all, then drink this again and try it." ”

Chang Shuang handed over another cup of medicinal juice.

"What is this?"

Although the color and taste of this cup looked relatively normal, Ehebai's face was still ugly, could she explain it clearly?

"It's an emet." Seeing that Ehebai was still staring at her, Chang Shuang explained, "The medicine I gave you just now has the ability to absorb bad substances, in order to let it absorb the poison in your body, now you need to force out what you just drank to see if you can bring the poison out, if you can vomit yourself, then you don't need to drink it again." ”

"I'll drink."

E Hebai simply took the medicine now, as long as he explained clearly and let him know what was going on, he was not an unreasonable person.

Ehebai is dry again, medicine is always bitter, and no one likes to take medicine.

After Ehebai drank the emetic medicine, everyone's eyes were fixed on him, expecting his change. Could it be that he was ready to pick up what his master spat out. Chang Shuang took a few steps away from Ehebai, worried that he would vomit on her.

Soon, E Hebai reacted, his face slightly bent over and opened his mouth with a hint of pain. He immediately handed over the basin.

"Vomit...... Ahem~"

It took a lot of effort for Ehe to vomit, he quickly wiped his mouth, drank tea and rinsed his mouth, if it wasn't for the extraordinary time now, he would never let himself lose his temper in front of others.
