Looking at Li Le's blazing eyes, Guayu was stunned for a moment, and then looked away, his face showed a little helplessness, and Li Le's heart sank.

"You don't know what this method is, do you?"

Li Le forced him to look him directly into his eyes, and sure enough, he saw the words in his expression.

"Just now, I've tried my own blood when I'm in the room, and it can indeed reduce the toxins in this water source."

Li Le paused, looking a little helpless. she

I thought that Hexagram Yu came to tell him this truth with full certainty, but he didn't expect that he didn't know it himself, and it was just a blind guess.

"But the only problem now is that I am only one person, and if I want to bleed, even if it is drained, I am afraid that the water source of the whole city will not be clean."

Li Le felt powerless.

Hexagram Yu sighed, "I really don't know, and it was actually an accident to train you to be invincible, and I didn't expect such a situation to occur at the beginning." ”

He also frowned, thought about it for a long time, but still couldn't come to a conclusion, so he simply sighed and found a place to sit down.

"I don't think it's that difficult, maybe you can try putting your own blood in the water source?"

Hexagram Yu raised her eyebrows, and suddenly felt that she was talking nonsense, Li Le had already said just now, if she wanted to bleed, wouldn't she drain her whole person?

He paused, and simply changed his words, "Perhaps...... It only takes a little bit of blood to purify the entire water source? ”

"Don't you know how big the water source base is for this whole process?"

Li Le looked at him incredulously, as if he had said some brainless joke.

But at the same time, she was also thinking about the truth of saying this, so she simply asked for a lot of the poison she found from her master, and then poured it all into a cup.

After weighing it for a while, he probably felt that this dose was enough to meet the water in a water tank, and even after that, he ran out with the cup and poured all the poison in the cup directly into the water tank.

As soon as all the poison in the bottle was poured in, the water in the tank began to tumble as if it were boiling, and bubbles began to bubble.

"Oh no, did I add more?" Li Le was stunned for a moment, and then a little annoyed, there was only some poison left in her hand, where would she go to find other medicines now?

What's more, even if she wants to formulate the ingredients of this poison now, and the names of two or three of the flavored medicines are still unknown, how can she configure them?

She looked at the tank in silence, and after about a cup of tea, he was surprised to find that the water in the tank had calmed down and returned to its original appearance.

Just look closely, but you can see that the water quality is slightly blackened, and you can see the bottom of the water tank, but now you throw something into it, and you can't see anything.

Li Le calmed down, this thing is not only poisonous, but even pollutes the water source, after this person drinks it, how can his body stand it?

Then, she gritted her teeth and cut the original wound on her palm, which hurt and injured Li Le in a cold sweat, and her trembling hand pinched several blood beads in her palm and dripped them into the water tank.

Then he quickly withdrew his hand and carefully observed the situation inside the water tank.

In the sunlight, Li Le could clearly see that after his blood beads fell into the water, it seemed to have volatilized directly, and he couldn't see a trace of blood appearing in the water at all.

"How is it like being devoured?"

Li Le felt a little uneasy in her heart and continued to observe, but soon she noticed that there seemed to be a black gas swirling in the water, gathering together and suddenly rushing towards the water.

She was astonished, and leaned back quickly, lest the black air rush straight in front of him, and then she saw the surface of the water, rising as if something had rushed out, and a moment later it hit the air like a fountain, and fell back into the tank.

"This should be considered as a poison that has been vaporized."

Hexagram's voice came from behind him at the right time, and his eyes were deep, and he didn't expect to see such a spectacle.

He was silent for a while, and when he saw that Li Le didn't answer, he looked over with some doubts.

I saw Li Lezheng observing the water tank intently, and when he saw her like this, he couldn't help but be a little curious.

He stepped forward, but listened to Li Ledao, "It seems that what you said should be right, my blood is indeed able to detoxify all kinds of poisons, and no matter how much it is, as long as it is dropped, it can be detoxified." ”

"But speaking of which, how do you know so much?"

As soon as the words fell, Li Le suddenly looked back at him, with a hint of exploration and consideration between his eyes, but Hexagram Yu did not dodge, just responded indifferently.

"And what is your status now? Who are you? ”

Hexagram Yu chuckled, originally Li Le thought he would laugh but didn't answer, but he didn't expect him to admit generously, "I am no longer the prince's staff." ”

"Not counted? Then you ...... now."

Li Le felt as if he had been circled by him, it had only been less than a month since this person said that he was the prince's staff, had he changed his mind so quickly?

"The prince is really too bored there, and he is helping him investigate things all day long, so he is really idle."

Hexagram Yu yawned very boringly, and then looked at Li Le with a little playfulness between his eyes, "I found that you are quite interesting here, and I am about to stay, I don't know if you accept people here?" ”

"With my ability, it will help you after all, at least I will enlighten you in this matter today, otherwise you really feel that you are going to sacrifice to the sky."

Guayu sneered, not caring if she would make a decision, just like a scoundrel, turned around and walked towards Li Le's study.

"Think about it, if you lose a talent like me, where can you find another one, don't say anything else, I saved your life two days ago, this condition should be able to let me live in, right?"

Li Le pursed her lips, of course she knew that Hexagram Yu was a capable person, especially when he helped him open the box full of hidden weapons two days ago, she knew that he had many skills that others didn't know.

Although this person looks very unruly, after getting along with each other so many times, she also understands that this person is by no means a mouthy woman with a long tongue.

Even if she took refuge with herself, she didn't hear her say a few bad words in the prince's mansion in the past two days.

And speaking of which, his invincible body is indeed trained by him......

Li Le gritted his teeth, and finally nodded, "Then you can keep it, you can still afford to eat with one more mouth." ”

The afternoon passed quickly, and the time of the three days was about to come, and tomorrow would be the time when the people of the city would be poisoned, and if this antidote could not be configured on the last day of today, I am afraid that it would ......

Li Le also got up on the fifth watch, and this time, she directly instructed others to hurry up to the water source to get a water tank and transport it back.

Today is the last day, they have wasted too much time, and after analyzing the poison for a long time, they have not been able to analyze what the two drugs are, it is better to investigate according to the quality of the water source.

Maybe we'll be able to find out something from that water source.

Li Le scooped a scoop of water and put it on the important table where he was working and handled, and then began to analyze it with Xia Heyi

It wasn't until noon that the two of them were busy sweating profusely, and finally compared the medicines that others hurriedly brought back from Beiliang to draw conclusions.

"This is the unique Manlingsan of the Beiliang Duoluo family, but this poison machine is complicated, we already knew it when we investigated before, and this thing has three flavor medicines, and we still don't know what it is."

Xia Heyi looked at it, quite helpless.

In the past few days, he has been busy in the past few days, he is an old man's body and bones are almost unbearable, not to mention anything else, there are already several more gray hairs in his hair alone, and he has a pain in the flesh when he pulls it out.

Li Le stepped forward to give Xia Heyi a slap on the shoulder, and poured him a glass of warm water quite intimately.

"But at least we know what the poison is now, we just need to find a cure for it."

Although she said this lightly, she also knew in her heart that it was not light at all.

It's just a short day's time, how can we analyze the remaining few unknown medicinal herbs?

If it's just an unknown medicinal herb, they still don't know what the consequences of this herb will bring, and this is what makes them most anxious.

Even if they can't develop an antidote, it can delay the onset of toxicity, which is still an antidote, and they are now at a loss.

She sat with a frown, her mind full of thoughts on what to do next, but the more she thought about it, the more she felt that things were a mess.

"If you haven't deciphered it today, tomorrow evening, the toxins in the people in the city will attack, don't be greedy anymore."

Guayu pushed the door in with lunch, and saw the two of them sitting together with a headache, so he couldn't help but remind,

"It always takes time for the drug to take time, poison is like this, and the antidote is the same, not to mention that the time for the antidote to take effect is probably longer than that of poison, so the estimated time I give is the most real."

After pondering for a moment, Hexagram Yu nodded, his face solemn.
