Out of the hospital gate early in the morning, Luo Sheng went to the breakfast shop in the city to have breakfast.

The shopkeepers, a husband and wife, were busy making stuffing in the house, and a stack of steamers at the door of the house was emitting white mist.

"What do you want to eat, officer?" The male shopkeeper kept wrapping the stuffing in his hand and greeted Luo Sheng.

"Let's have 10 steamed buns and a bowl of porridge."

It was still early, and on the bench under the shed in front of the store, there were only two or three ragged porters, one holding a bowl of gruel and drinking.

Luo Sheng took a small bowl of vinegar, chili peppers and pickles, and also found an empty seat and sat down.

Soon, the shopkeeper brought ten steaming steamed buns, followed by a bowl of gruel.

"Guest, please use it slowly."

The steamed bun is the size of a fist, the skin is thin and the filling is thick, and the green onion is more and less meaty, but the taste is not satisfactory.

Things are very cheap, 10 buns and a bowl of gruel are only 6 yuan.

After eating, Luo Sheng took out 9 small coins and put them on the table, and packed 6 buns with oiled paper to take them away.

Coming to the hospital,

At this time, there were naturally no patients, Shi Qing was lying on the counter and snorting, and greeted Luo Sheng after seeing him,

"Here we go."

Putting the oil paper bag in his hand in front of Shi Qing, Luo Sheng said, "Senior Brother Shi, is there a book introducing poisons, I want to know about it." ”

"Yo, it's hot!"

Shi Qing picked up a bun and took a bite, and said vaguely:

"The Tang Gate Poison Sutra records many strange poisons, which are forbidden books of the Tang family that the owner is not qualified to learn, and I can't show it to you."

Luo Sheng frowned.

Good fellow, he still thought that he would be able to identify poisons on his own in the future, but he couldn't learn them.

But it makes sense to think about it, if that kind of poison can be learned at will, how can the Tang family still be known for its peerless poison?

Is there really no poison in the medical hall?

Not necessarily, because even if there were, it wouldn't be possible to give him an apprentice, would it?

"However, for the sake of these buns......"

Shi Qing took out a book from under the counter and put it in front of Luo Sheng,

"Although it is impossible for you to show you the Poison Sutra of the Tang Sect, this is my own summary of notes on poisons, which record hundreds of common poisons.

"Of course, in terms of quantity and toxicity, it is far inferior to the real Poison Sutra, if you are interested, take it and see it."

Notes on poisons?

Luo Sheng took the book, moved a stool and sat behind the counter, and read it intently.

The book is full of dense and neat small print, and the table of contents and page numbers are listed in detail on the first few pages, which shows the intention of the author.

This really made Luo Sheng take a high look at Shi Qing, a doctor who was a little unserious from time to time.

Judging from the catalog, there are poisonous animals such as the five poisons, poisonous plants such as aconitum, strychnine, oleander, etc., as well as arsenic, cinnabar, etc.

Open it and look closely, each poison is detailed with information such as characteristics, origin, toxicity, and various medicinal values, which is extremely detailed.

After Luo Sheng quickly flipped through it for a while, he suddenly asked:

"Senior brother, are those poisonous arrows and poisonous daggers in the legend the snake venom smeared above?"

Regardless of whether you can't ask, almost all of the records in the book are medicinal values, and there are no relevant labels at all.

Shi Qing glanced at him suspiciously, "I see that you really like to ask about this stuff!" Do you still want to practice martial arts? ”

Luo Sheng said quite naturally: "I often hear the chivalrous stories of Mr. Storyteller, and there is no man who doesn't like swords and martial arts, right?" ”

"There's some truth to that."

Shi Qing nodded, "Then I'll tell you, it's not as simple as in the book, and poison can't be used just by applying it to weapons."

"Most of the poisons of insects and snakes, such as snake venom and scorpion venom, will rot and lose their toxicity after leaving the body, at least a quarter of an hour, or at most a day.

"Unless it is kept in an ice cellar, or by using the secret method recorded in the Tangmen Poison Sutra, it can be specially purified and dried for a long time.

"Otherwise, you want to smear your weapon with snake venom, unless you have a live snake with you, you can ensure that you have fresh snake venom at all times."

I see.

Luo Sheng nodded secretly in his heart, and asked again: "What kind of poison is the poison that is smeared on the blade of the knife and sealed the throat with blood?" ”

Shi Qing said: "If there is no secret method of the Tang Sect, it is more convenient to have a highly poisonous thing, which is often smeared on arrows by the army.

"This poison used to be very common and spread all over the country, and had a variety of medicinal effects such as cardiotonics, vomiting, diarrhea, and anesthesia.

"But later, the imperial court banned this kind of convenient poisonous substance from appearing among the people, and dispatched the army to collect it on a large scale, which became very rare."

Luo Sheng asked, "What is it?" ”

"A kind of tree is called the Blood Sealed Throat Tree, also known as the arrow poison wood!

"There used to be many Mangshan mountains, but they were all destroyed later, maybe in the depths of the inaccessible mountains, you can find some remnants......

……

After leaving the hospital at noon, Luo Sheng returned to the small courtyard after having lunch outside.

"See the ...... of the Bloody Throat Tree"

There is a record of this poisonous tree in Shi Qing's notes,

The sap of this tree is extremely toxic, once it comes into contact with human and animal wounds, it can make the poisoned person paralyzed, the blood vessels are closed, the blood is coagulated, and the suffocation is killed, so the name is blood to seal the throat!

Under a sufficient dose, even large beasts can be poisoned in a short period of time, and martial artists in the health realm can't bear it at all.

Moreover, there is almost no solution to this poison, and the only antidote is a plant called red-backed bamboo pole grass that grows around the blood-sealed throat tree.

It is precisely because it is too powerful and not as difficult to obtain as the Tang Sect's absolute poison that it was completely banned by the imperial court, and it has become very rare from wide distribution.

"Let's look in the mountains another day......

The deepest part of Mangshan is inaccessible, and Luo Sheng has never been there, and he doesn't know what plants and beasts are hidden in it, or even relict monsters like strange birds?

After making this decision, he began to sit cross-legged on the bed and meditate and cultivate.

Using poison is not the right way to martial arts, and he will not spend too much energy on it, at most it is just an auxiliary means.

His goal is not to use a poison master, but to be a martial arts powerhouse, and his main energy will always be on physical cultivation and true qi cultivation.

Settle in, practice boxing, dinner, practice boxing, settle ...... An unusually fulfilling day and a night passed like this.

Early the next morning, after a whole night, Luo Sheng, who was sitting cross-legged on the bed, slowly opened his eyes.

"Why? It's ......"

At this time, in his body, after a day of cultivation, that trace of true qi did not continue to grow, but split out a new silky true qi!

The two True Qi are equally flexible, sharp, and slender.

Luo Sheng can control them to fuse together to become a slightly thicker one at will, and he can also separate them at any time, and even make various twisting and spiral tricks.

"As the True Qi gets stronger and stronger, wouldn't it be possible to separate countless filamentous True Qi?"

Luo Sheng had an understanding in his heart.

"Could this be the mystery of Mochizuki's true qi? Gathering is a ball of steel, and scattering is ten thousand needles? ”
