Sustained release, as the name suggests, is a way for chemicals such as drugs to be released in a slow manner. Pen? Interesting? Pavilion wWw. ｂiquge。 For example, many cold medicines in later generations are extended-release medicines.

When Yang Huairen was studying at a chef school, he once saw a food release technique in extracurricular readings that was used to make food for diabetics.

He felt that such a technique could also be used to poison the enemy. Without professional production equipment, he can only use a self-created local method.

Tetrodotoxin powder is mixed with dried corn starch, then pressed into a starchy egg the size of a mung bean, wrapped in egg white, slightly heated by steam, and then supplemented with mixed powder, then wrapped and pressed, and finally made into egg-sized balls.

Fry the meatballs in oil, mix them into a seasoning packet, and put them in a large pot of pork when the time comes, and you're done.

When this seasoning packet is placed in a large pot where the meat is cooked, the toxic drug wrapped in the meatballs does not immediately dissolve into the broth.

The meatballs are constantly heated and slowly dissolved, and the poison will be slowly diluted into the broth layer by layer, because the amount of toxin is well grasped, and most people will not have an obvious reaction when a certain amount of toxin is ingested at a time.

However, with the normal rate of human metabolism, it takes three to six months for the drug to be completely eliminated from the body, so the previously ingested toxins will not be eliminated from the body in a short period of time.

And with the second and third successive ingestion of a certain amount of toxin, the accumulation of toxins will make the human body have a poisoning reaction, even if it is not immediately fatal, it will be uncomfortable and lose its combat effectiveness.

If the Xia army is successful, within two to three days, there will be a large-scale poisoning, resulting in a sharp decline in the overall combat effectiveness, and even if the Song army is small, if it wants to fight back, the Xia army will have no power to fight back, and can only be killed.

Tong Guan and Yang Shihu felt that Yang Huairen's method was a bit incredible, but they were understanding people, although they didn't understand the meaning of the sustained release technique, they chose to believe Yang Huairen, because there was no other way.

On the fifth day after the first attack of the Xia army, there was a new movement in the camp of the Xia army, more than a dozen brand-new catapults were built, and Yelituri once again led the army to attack Qingping Pass.

Early in the morning, the sound of the Xia army's drums marching sounded again, and the catapults were placed in the array, and even the soldiers beating the drums seemed to have more strength, and the drums looked more confident than in the previous days.

On the side of the Song army, the wounded and non-combatants who should have been evacuated have been evacuated from Qingping Pass, and they did not stop all the way, and directly withdrew to Tongyuan County, and the passes and camps along the road and Dongchuan were also evacuated one after another.

The Xia army marched to a place two hundred paces away from the city of Qingping Pass, stopped, and a group of Xia soldiers with loud voices stood up and began to curse in Song dialect.

Ye Lituli is a little funny, I didn't think about scolding when I attacked a few days ago, but I don't know what happened today, maybe because I was full of confidence after having a catapult, and I didn't want to let go of this opportunity to pretend to be forced.

However, this Xia Jun's scolding words don't sound very good, they are nothing more than the most ordinary vulgar words, and the meaning expressed is relatively clear, that is, handing over Yang Huairen can give Huanzhou a good death, otherwise, the corpses will be broken into thousands of pieces, and the chickens and dogs will not be left.

Yang Huairen felt that this scolding had no culture and no art, since it was a death to surrender or not, who would be sick and surrender?

If you put it another way, such as promising a thousand eight hundred taels of gold and silver treasures or dozens of Xixia beauties or something, maybe there are still weak-willed people who can consider it.

From this, Yang Changeren can judge that Ye Lituli is also a poor ghost in Western Xia, and he must not have many gold and silver treasures or few beauties in his family.

However, what makes Yang Huairen feel funny is that since ancient times, the words of scolding have always been the same, and he can't forget to greet people's mothers or other women, saying that thousands of people sleep and ride thousands of people, and there is no difference from later generations.

But to express the same meaning, it seems that there is no technical content in scolding people like this, Yang Huairen whispered a few words in the ear of the loud Tianba younger brother, and let him pass it on.

Song Jun began to scold back.

Xia Jun shouted, "Sleep with your old girl", and Song Jun scolded back, "Your old woman sleeps with me, and I have worked hard."

Xia Jun scolded the generals and didn't react for a while, and when they thought clearly, they scolded harder, of course, their scolding still didn't have much connotation, and it was just a few words over and over again.

Song Jun was guided by Yang Huairen, and the level of scolding was obviously much higher, at least he seemed more educated, and he didn't use dirty words at all.

For example, "I am your long-lost father", "You are all the flowers of the motherland, the kind that is specially planted in cow dung" and so on.

Anyway, Xia Jun understood some words, but he didn't understand some words, so it's no wonder that Yang Huairen is more serious and boring than a bunch of uneducated.

Scolding dryly, Yang Huairen saw that it was almost time, and began to gesture to the soldiers of the Song army.

Soon the soldiers of the Song army stopped scolding, stopped and began to eat and drink, with a wine jug in their left hand and a big bone stick in their right hand.

Just now, Song Jun's side scolded the formation and gained the upper hand, and he really took advantage of the upper hand.

Now it's spring, the southeast wind is blowing, Xia Jun tore his throat when he scolded, and his voice was half pushed back by the wind, but Song Jun shouted casually, and the scolding spread farther.

Now before the battle to drink wine and eat meat, the spring breeze continued to help, dozens of cauldrons added fire, the pot was full of beef and mutton, bubbling with the smell of meat, each pot arranged a few gang leaders to fan along the wind.

Yang Huairen was even happier, thinking that Zhuge Liang had asked Dongfeng for help in setting down the Seven Star Altar, so that he could burn Chibi, and today he saved the strength of the altar arrangement, and the spring breeze volunteered to help, so that he could use food to kill Xia Jun opposite.

Regardless of whether Xia Jun's shield wall array is really ironclad or not, but when a person smells the fragrance of food, he can't stand this temptation, and salivating is definitely inevitable, this is the nature of human beings, and no one can escape it.

Watching Song Jun leisurely drinking and eating meat in the city, Xia Jun was so greedy that he could only swallow saliva one after another, thinking that Song Jun's food was indeed better than ours, and the meat was so fragrant.

Ye Lituli felt that this was an insult to him by the Song army, and with an order, more than a dozen catapults were pushed out and slowly began to advance towards the predetermined stone throwing position.

Seeing this, Yang Huairen shouted, "Brothers, according to the pre-formulated method, listen to my command, run!" ”
