Cheng Guanyue was someone who would do whatever she wanted, so she and Cheng Weiwu went into hiding at the home of one of the most famous doctors in the capital.

"Boss, when do you think that Dr. Wu will return? I can't wait any longer." Cheng Weiwu and Cheng Guanyue were hiding in Dr. Wu's medicine hut. Other than Dr. Wu who usually entered the hut, the others were not allowed to trespass without permission, even his apprentices were not qualified to trespass into the hut.

As a result, even if they were to engage in a secret conversation, they were not afraid of being discovered.

The most important thing was that this medicine hut was filled with many rare and precious herbs, as well as all kinds of strange pills. Dr. Wu reckoned that this was the place where Dr. Wu would usually conduct experiments.

They would never allow anyone to barge in, otherwise they would accidentally eat something bad, wouldn't that be the end?

"Wait a little longer, he'll definitely be back soon." It was already midnight, so it was impossible for Dr. Wu to not go home to rest. After all, this Dr. Wu had a very strong sense of time, so when it was time to go home, he would definitely come back and take a good rest.

Moreover, this was the result of Cheng Yingwu and Cheng Shenyong's investigations.

Seeing his boss was so sure, Cheng Weiwu didn't say anything for the time being.

However, three minutes later, just as his boss had said, Dr. Wu carried a medicine chest on his back and walked over to the medicine hut first, to see if there was anything unusual about the hut.

However, before he even had the chance to light the lamp to look at the things inside the medicine hut, Cheng Guanyue and Cheng Weiwu took the lead to hide behind the hut's front door.

As a result, the moment he entered the door, Cheng Weiwu covered his mouth tightly, preventing him from making even the slightest sound.

The instant that Dr. Wu entered, Cheng Guanyue closed the door to the medicine hut.

He wasn't afraid that Su Family guards would discover something amiss. After all, every time Dr. Wu returned home, he would enter the medicine hut to check on something.

Even if the Su Family guards wanted to protect his family and life, he had to hide somewhere outside the medicine hut, somewhere in the corner. He couldn't just casually step into the medicine hut.

This way, Cheng Guanyue and Cheng Weiwu would have enough time to interrogate Dr. Wu.

"I'll tell you, I'll let you go, but you must not make a sound, or else I'll kill you with this blade, understand?" Not only did Cheng Weiwu threaten him like this, he even brought the large blade closer to his weak neck. He was just a centimeter away from touching Dr. Wu's carotid artery.

"Um... "Ugh!" Dr. Wu could not speak and could only nod his head with all his might, issuing a few small sounds of agreement.

Seeing that he agreed, Cheng Weiwu slowly let go of his left hand, allowing Dr. Wu to breathe smoothly.

"You … "Who are you?" Dr. Wu pointed at Cheng Weiwu and Cheng Guan Yue in shock.

"Don't ask who we are. This is not good for you. We just want to know if the reason why you went to the Su family with the other doctors in the capital every day was to refine some Energetic Pill?" Cheng Weiwu didn't want to waste any more time and directly asked him.

"You … How do you know? " After Dr. Wu finished speaking in astonishment, he covered his mouth, realizing that he said the wrong thing and leaked the information, it was equivalent to admitting to the fact that the Su Family went to find them, the doctors, for their true purpose.

"Alright, you said it already, why are you still covering your mouth? It's not like we don't know about this fact. Furthermore, we came here in the middle of the night with no other purpose, we just want to ask, who has the Energetic Pill's pill formula?" Maybe you can copy the pill formulas and give us a copy of the antidote. If you can't, give us the antidote for the Energetic Pill. " Cheng Weiwu said that, but in truth, he wanted to get both the pill formula and the antidote.

"I... "I don't know about pill formulas. They're not in my possession, and I don't have the antidote either." Dr. Wu trembled in fear and panic.

"No, how could that be possible? You must be lying and lying to me." As a doctor, how could he have such poor memory? He couldn't even remember a single pill recipe.

As a result, Cheng Weiwu did not believe that this Dr. Wu knew nothing at all.

"I... I really don't know who possessed the pill formula, and I didn't record it down either. " Although Dr. Wu was afraid of death, he still understood that Cheng Guanyue and Cheng Weiwu had other things to ask of them, and would not kill him as they pleased.

In addition, his wife and children were both in the hands of the Su Clan.

Thus, he could only deny that he knew the pill formula, and he did not remember it.

"Continue pretending. Who doesn't know that you have the best medical skills in the capital. The Su Clan will definitely let you have a look at the pill formulas, or else they will be with you." Cheng Weiwu swept a sharp gaze across his entire body, and also searched him.

Who knew that the pill formula was not in his hands?

On the other hand, Cheng Guanyue had excellent night vision. Moreover, the moonlight was bright tonight, allowing her to clearly see everything through the medicine hut's window.

Coincidentally, her gaze had been looking at every pellet Dr. Wu had concocted, and finally found the most difficult bottle of poison, as well as the antidote Dr. Wu required every month.

Then, he opened Dr. Wu's mouth, and without waiting for him to struggle at all, he consumed the bottle of poison he had created.

"I think you should know yourself what I gave you. And I think you should know how difficult it is to develop an antidote like that. " Just now, after looking at every pill that he had concocted, Cheng Guanyue found that the antidote for the pill that he had given her was the least, and also the rarest and most precious one.

Other antidotes could be concocted using at least one or two bottles of poison, but this one was only half a bottle. Furthermore, it was one bottle per month, no more, no less.

"Exactly, if you don't listen, then we'll take this antidote away, not leaving a single one for you." Even if you were to start developing now, I think you would not have enough time. Furthermore, the harder it is to create an antidote, the rarer and rarer the medicinal ingredients are. Don't you know this better than us? " Cheng Weiwu also felt that Cheng Guanyue's method of poisoning him was not bad.

After all, was not like before, where he could force him to speak the truth with a beating.

Firstly, they had to consider the fact that if Dr. Wu brought an injured person to the Su Family, he would definitely be discovered by others. Needless to say, there was a Su Family guards outside protecting Dr. Wu.

Even if she didn't hit him in the face, it would cause internal injuries.

That would still not do, if the old cunning fox from the Su Family could see that Dr. Wu was injured, wouldn't he be beating the grass and alerting the snake?

Thus, the safest method was to use poison.

In any case, there were no scars on the surface or on the inside. It was both invisible and reliable.

"You … "You all..." Dr. Wu looked at them with extreme fear and fury, but had nothing to say.
