The city gate has two layers, and the second layer's defense is more solid than the first layer.
At the same time, lookout holes were set up, so that people could throw stones and shoot arrows into the narrow holes in the city gate, and also see the siege situation clearly.
Moreover, the outer city gate is designed to open outwards, while the inner city gate is designed to open inwards.
Therefore, the outer city gate was broken, and at this stage, the battle at the city gate was a showdown of power.
The attacking party will push inwards with all their strength, while the soldiers inside will push outwards in a stacking manner.
Although huge wooden bolts had been placed on the city gate long ago, they were also supported by huge logs.
However, there were too many northern barbarians rushing in, and with the pushing and pulling outwards, it didn't take long for the entire city gate to collapse.
"Fire oil."
Linghu Xiaoshan shouted at the people guarding the city gate.
The soldiers on duty immediately took out cans of kerosene and poured them down from the city wall frantically.
Kerosene has always been a siege weapon, but its production is scarce.
Moreover, there is an essential difference between kerosene and rolling logs and thunder stones.
The damage caused by rolling logs and thunder stones is only short-lived, while the burning time of kerosene is long enough to block the enemy's time to break through the city gate.
But there is also a problem, that is, it is possible to set the city gate on one's side on fire as well, which will only make breaking the city gate faster.
But at the moment, there is no other way except kerosene.
Looking at his daughter's anxious look, Linghu Zheng understood very well what he was thinking.
"Everyone, prepare for defense, circular formation."
"No matter how many people rush in, we are the barrier that cannot be crossed at the city gate."
"Brothers, remember this: as long as we hold on, Tianyong City will be there. If we retreat, the brothers on the tower will have died in vain."
