Not now, since the Northern Song Dynasty there have been extremely scary biochemical weapons

During the Song Dynasty, a weapon model similar to a biochemical weapon appeared. Not only can it explode, it can also emit toxic smoke, causing great damage.

According to research, gunpowder officially appeared in the Tang Dynasty (late 9th century), developed by ancient alchemists. From the Warring States period to the beginning of the Han Dynasty, Chinese emperors and nobles constantly indulged in the dream of immortality, from which a number of alchemists and Taoists appeared, continuously studying the elixir. . In the process of practicing singles, they accidentally invented the gunpowder recipe.

During the Song Dynasty, there was a terrifying biochemical weapon called "Singing Potion".

However, because gunpowder could not solve the problem of immortality and was very flammable, the alchemists were not interested in it. The recipe for gunpowder was passed from alchemists to military strategists, becoming real gunpowder - one of the four great inventions in ancient China.

Before gunpowder was invented, fire attack was a common attack method used by military strategists. At that time, for fire attack, people used a weapon called rocket, which fired fiery arrows used to burn down strategic enemy positions. However, when gunpowder appeared, fire attack was raised to a new level.

During the Tang Dynasty, gunpowder was packed and ignited and thrown into the enemy's battlefield with great effectiveness. This is also considered the world's first "hot weapon". By the Song Dynasty, this heat-seeking weapon had developed extremely quickly and became popular. The government even set up a department specializing in the production of weapons from gunpowder. In it, a weapon model similar to a biochemical weapon appeared.

The ancient military book "Volunteer Compendium" of the Northern Song Dynasty once recorded a weapon called "Saning Poison", which detailed the production methods of this biochemical weapon. It is mentioned that this weapon not only contains gunpowder but also contains extremely toxic substances. This weapon is meticulously crafted, carefully calculated to ensure it only explodes when thrown into the enemy's battlefield.

The goal of this weapon is to make a loud noise, explode quickly and powerfully enough to scare the horse into running away. At the same time, the poison in it is also burned, creating toxic smoke. When the toxic smoke spreads, the smoke goes wherever people and horses inhale, they will be poisoned immediately, if it's light, the nose and mouth will bleed, the limbs will be paralyzed, and if it's heavy, they'll die.

However, even with such powerful biochemical weapons, due to the national policy of respecting martial arts, the Song dynasty could not eventually revive, the national energy became increasingly weak and weak. troops shielded, protected, and finally destroyed by the Kims.
