Dusk and sunset.

Chu Mu was holding a piece of clothing, and at the gate of the courtyard, the little widow was a little shy, only the graceful back remained, and soon disappeared from Chu Mu's field of vision.

"Funny ......"

Chu Mu chuckled, the little widow's sudden thanks were a little beyond Chu Mu's expectations.

Spread out the green clothes in his hand, just at a glance, Chu Mu could be sure that this green clothes also fit him well.

This little widow is really funny.

Until just now, he didn't know the little widow's full name, surnamed Li, named Caiyi, and no more than twenty-eight years old.

In the next life, she is still an ignorant girl, but in this life, she has experienced too much.

Standing in the courtyard for a moment, he raised his hand to roll up his clothes, and stared for a moment, but Chu Mu shook his head, then turned around and walked into the room.

The unfinished brainstorming continued again, and the lingering medicinal fragrance seemed to become more and more intense under the experiments.

It wasn't until twilight fell and Xu Yuan's arrival that Chu Mu's concentration could be interrupted.

"Brother Mu, what are you doing here?"

Xu Yuan looked around the room, obviously confused.

"You'll find out later."

Chu Mu gulped the food Xu Yuan brought and said vaguely.

Immediately, Chu Mu seemed to think of something, looked up at Xu Yuan, and changed his words:

"By the way, if you patrol the streets in the next period of time, you can pay attention to the little widow next door for me, and if there is any trouble, deal with it."

Xu Yuan's eyes widened, as if he had heard a shocking secret: "Brother Mu, you and that little widow ......"

"!"

Chu Mu scolded angrily: "What are you thinking, I saved the little widow once when the people were in turmoil before, and today the little widow came to thank me and gave me a set of clothes." ”

"Since there is a relationship between people and people, we can't sit idly by......"

Xu Yuan looked like he had seen it through, and immediately patted his chest and promised: "I understand, I understand, Brother Mu, don't worry, I'm here, don't worry, whoever dares to harass me, I'll break his legs ......"

Seeing this, Chu Mu didn't bother to explain, this kind of thing, the more he explained, the more he couldn't explain it, and the more he had a feeling of wanting to cover it up.

After finishing the meal, Chu Mu got up, walked straight to the medicine cabinet, shook his hand again, changed the essence and qi dissipation, and started the experiment.

About half an hour later, the hot medicinal juice was placed on the table again.

Only this time, the porcelain bowls on the table were not one, but two, and both of them contained medicinal juice.

"Come, one bowl per person, don't waste it!"

Chu Mu picked up the porcelain bowl and handed it to Xu Yuan.

Xu Yuan was puzzled: "Brother Mu...... This is? ”

"The improved version of the essence qi is dispersed, this is already the sixteenth edition, it shouldn't be a big problem, you can also taste it, and then perceive the changes in the medicinal properties, and then tell me ......"

After speaking, Chu Mu swallowed the hot medicinal juice, seeing this, Xu Yuan did not hesitate, he also drank it all, seeing that Chu Mu had closed his eyes and sensed it, Xu Yuan also followed the same path to close his eyes and perceive the qi and blood.

Nearly a quarter of an hour later, Chu Mu slowly opened his eyes, and the "Spiritual Blessing" slowly dissipated, and the depth in his eyes also turned into a little doubt.

Walking to the table, holding the pen and dipping it in ink, Chu Mu did not put down the pen for a long time.

"Brother Mu, the effect of the medicine is so strong, it is more than twice as strong as my essence qi dispersion!"

Xu Yuan was obviously very excited, and even a little incredible.

Chu Mu spoke up: "Tell me how you felt just now." ”

Xu Yuan recalled: "If you feel it, the medicine is so strong, and then you feel a little uncomfortable in the heart, and the rest is fine......"

Chu Mu groaned, and after a long while, the pen finally fell.

The eighteenth change of Jing Qi Dispersion, compared with the seventeenth change of Jing Qi Dispersion, the improvement of the efficacy is weak, compared with the original Jing Qi Dispersion, the efficacy of the drug is about doubled......

The problem of toxin load is still not solved, and long-term use may lead to overload of the heart and be life-threatening......

If used normally, it should be taken once every 10 days and should be accompanied by an antidote to the toxin......

Lines of handwriting fell, and finally, the pen stopped, and Chu Mu frowned and pondered.

From the first change to the current eighteenth change, the main credit for the leapfrog improvement of the efficacy of Jingqi Dispersion lies in the complementarity of the prescription.

The so-called strange refers to poison, and it is highly poisonous!

The existence of severe toxicity, under the neutralization of the main auxiliary drug, eliminates part of its toxicity, and uses its toxicity to greatly promote the efficacy of the main drug, and it can even be said to be sublimated!

But it is also an unavoidable problem, and that is the existence of residual poison.

If you need to use its poison, you can't concoct and weaken its poison in advance, but only neutralize and weaken its poison within the scope of the prescription on the premise of letting its poison work.

Success is also poisonous, and defeat is also poisonous!

At present, the eighteenth change is dissipated, and it seems that it has fallen into this strange circle.

Even if the effect of the medicine is good, but the negative effect is so great, this prescription has no meaning.

The most important thing in the essence qi dispersion prescription he wanted was not the efficacy, but time.

Like the original Jing Qi Powder prescription, the effect of the medicine is not good, and it has to be taken once every few days, just the limitation of time, it is destined to be flashy!

At the moment, if he doesn't solve the problem, he has to prepare an antidote at an interval of ten days, which is even more flashy!

"Change the adjuvant...... Or is it the opposite? ”

Chu Mu frowned, thought for a long time, and moved the stagnant pen again, and the nineteenth prescription slowly appeared on the white paper as Chu Mu thought.

As the night deepened, Chu Mu was still busy in the room, and Xu Yuan, who was called by Chu Mu, also became the material for another human experiment of Chu Mu.

The prescription was changed again and again, and in the end, it was tried on Chu Mu himself and Xu Yuan.

Until late at night, this experiment could not be stopped, Chu Mu slept directly with his clothes, and Xu Yuan ran to the next room to spend the night.

And in the next ten days, Chu Mu's life seemed to pass in an orderly manner in such a demonic state.

Experiments day and night, changes in the prescription of Jingqi San, and even sometimes changes the experiment several times, and then directly overturn the idea and start over, I don't know how many times.

Xu Yuan has been reduced to free material for human experiments, and every day as soon as he is on duty, he will go to Chu Mu's house on time...... Try the medicine!

Chu Mu did not ask for help from Li Lao.

Although he knew very well that the question that made him meditate hard and couldn't solve it might be a matter of one sentence in Li Lao's mouth.

But after months of hard study and huge knowledge accumulation, Chu Mu still hopes to solve the problem completely by himself.

Under the experiments again and again, on the light curtain panel, the visible entry of the essence and qi dispersed seemed to prove the correctness of his independent thinking and experiments.

The experimental process of combining theory and practice is a growth process for him.

Turning to Li Lao for help will only make his growth imperfect.

This may be a bit paranoid, but Chu Mu is very determined......
