How dare these messengers be negligent? They quickly passed on the order.

Li Yuanqing's kerosene was piled up in the cool ground inside the city wall.

Most of them are packed in pine barrels sealed with pine oil, which are similar to the oil barrels of later generations.

Another part is contained in a clay pot the size of a small watermelon. The mouth of the clay pot is very thin and shaped like a pear, which is the incendiary bomb carefully developed by Li Yuanqing.

The fuse is connected to the mouth of the pear, on the one hand, it is convenient to accumulate power when it explodes, and on the other hand, it is also for the pitchers to have a grip point, making it easier to throw.

Unfortunately, in this state, they obviously cannot make a grand appearance.

There have been a thousand auxiliary soldiers on standby under the city wall for a long time, but at this time, they didn't care whether they were auxiliary soldiers or combat soldiers. Everyone worked together to carry oil barrels and incendiary bombs to the top of the city.

Li Yuanqing would no longer be stingy, and shouted loudly, asking the soldiers to pour the treasures in these oil barrels along the city wall into the water of the moat below.

Not long after, the thick smell of fire oil mixed with the rain began to permeate the air, getting stronger and stronger.

Li Yuanqing shouted something loudly to Niu Gensheng. Niu Gensheng understood the situation and ran quickly to a hanging door, blocking the wind with his body, and carefully took out the flint and the fire stick wrapped in oilcloth.

After a few minutes of hard work, Huozhezi was finally ignited. How could he still hesitate? He quickly took out a burning fuse soaked in oil, carefully lit it, and threw it into the moat at his feet.

For a moment, there was a sound of "Plop, Long," and then one after another, there was a "Plop, Long, Long" sound.

It was like a spark hitting the earth. The kerosene and sparks reacted instantly. After a series of small explosions, a raging red fire suddenly rose in the moat against the heavy rain like pouring beans.
