Terrifying rotten skeletons, like black tides, quickly gush out from underneath the shield formation.
These skeleton warriors put their weapons and blades in their mouths or inserted them into their skeleton bodies. Like geckos, they pressed their hands and feet against the rock wall and began to climb up.
As a general who has experienced hundreds of battles, Zhao Zian naturally has already thought of a countermeasure.
From the numerous holes above, fierce fire oil began to be poured down.
Unlike the Yingzui Cliff defense line that used bamboo pipes to spray outwards ten years ago, Yumenguan adopted a dumping tactic.
The fierce fire oil flowed down the stone wall, and soon the stone walls of the main defense line were covered with fierce fire oil.
When a torch was thrown down, the rock wall about two miles long and more than thirty feet high suddenly turned into a wall of fire, with black smoke billowing into the sky.
The countless skeleton warriors climbing above were instantly engulfed in flames.
These skeleton warriors are undead themselves. In hand-to-hand combat, the only way to kill them is to break their skulls.
If you just cut off their bones, you won't be able to kill them at all.
However, skeleton warriors also have weaknesses.
No matter how it is changed, the attributes of the undead still belong to the cold and cold category.
The best way to deal with them is to use pure yang to strong attribute power.
Flame is a typical representative of pure yang.
It is also the greatest nemesis of the undead warriors.
Hundreds of skeleton warriors who had climbed up the city wall screamed in the flames, and then fell from the city wall.
But this did not stop the heavenly army from attacking the city. A steady stream of heavenly armies rushed to the bottom of the city wall and formed a solid defensive formation.
Then, the large wooden barrels used to store grape wine in the Western Regions were carried under the city wall by the madman warriors behind them.
The wooden lid was opened, and of course it was not expensive grape wine, but a pale white viscous liquid.
Every skeleton warrior jumped into the barrel, soaked his whole body, climbed out, and rushed into the wall of flames.
It is strange to say that the skeleton warriors who have absorbed this mysterious white liquid can actually swim in the flames like fish in the water, and the flames will not cause fatal damage to them.
This is the first time in millions of years that the heavens have used fireproof liquids in a catastrophic battle.
After the wall of flames was no longer a threat to the skeleton warriors, the Celestial Legion formed a morale formation.
Some mad warriors became extremely irritable after becoming mad. They grabbed the wooden barrels around them and poured the fire-proof liquid on themselves.
Then start climbing up like a skeleton warrior.
However, they don't have the skill of climbing vertical walls like the skeleton warriors, so they can't climb up at all.
Soon, the human warriors discovered that the heavens were using new weapons, and immediately passed the news to Zhao Zian, who was watching the battle in the Que Tower.
When Zhao Zian and others heard that the heavenly warriors were not afraid of fire, their expressions changed drastically.
Phantom took them by surprise and used fire retardant fluid, catching them off guard.
Zhao Zian quickly calmed down and said: "Let the rolling wood go."
Rolling wood is already the last weapon in the first line of defense. Zhao Zian will not use it easily unless it is absolutely necessary.
Rows of huge gaps appeared on the rock wall about a few dozen feet above the ground.
Huge logs pulled out by thick iron chains were pushed out one by one. The logs were three feet long and more than five feet in diameter.
The surface of the log is wrapped in thick iron armor with countless spikes of different lengths, like a giant mace.
At a glance, there are countless huge rolling logs hanging in a row on the two-mile-long gate.
This thing was used in Wangfu Ridge and Duoshi Peak ten years ago during the Battle of Yingzui Cliff.
However, the rolling logs of ten years ago exposed many shortcomings in actual combat.
At that time, Yang Zhentian placed the iron rolling log weighing 10,000 kilograms on the only gentle slope in the north, and then pulled it through iron chains.
Mortals can't pull it. Inside the rock wall, many monks from the Royal Cultivation Academy are responsible for pulling the winch and recovering the rolling wood.
However, since the slope is not very steep, it will be difficult to retrieve the rolling log once it is filled with corpses. The giant warrior can quickly cut off the huge chains involved with the giant ax in his hand.
After learning from the experiences and lessons learned ten years ago, craftsmen made many improvements to the rolling wood.
First, the iron chain that pulls the rolling logs has been made much thicker, and two more chains have been added to pull it.
The second is the battlefield environment used.
The reason why the rolling logs on the Wangfu Ridge defense line ten years ago did not have very good results was mainly due to lack of experience and lack of consideration, so that the chains were quickly chopped off by giant warriors with giant axes.
The rolling logs now placed on major passes such as Yumen Pass and Shanhaiguan no longer roll on gentle slopes, but fall almost vertically against the Queguan city wall.
In order to prevent being attacked by giant warriors, the chains placed on the rolling logs have been strictly measured and calculated. When the rolling logs fall to about four feet from the ground, they will stop falling.
In this way, it would be difficult for the giant warriors two to three feet tall on the ground to cause damage to the rolling logs.
The main task of the rolling log is to smash the enemies climbing the city wall to death, smash the enemy's siege ladders, and effectively stop the enemy's siege speed. It is not to kill the enemy to the greatest extent.
Countless skeleton warriors soaked in fire-proof liquid climbed up the rock wall of Yumen Pass. They crossed the sea of fire and climbed up at extremely fast speeds.
In just a moment, thousands of skeleton warriors were hung on the city wall. The top skeleton warrior was already less than ten feet away from the first line of defense.
Following the general's order from the forward position, countless large wooden hammers hit the machine brackets.
Countless rolling logs hanging in a row above the rock wall crashed down with thunderous force, and countless cold iron chains thicker than arms were stretched downwards, making a clattering sound.
Each rolling log weighs tens of thousands of pounds, and they almost fall against the rock wall.
The sharp spikes installed on the surface of the rolling wood scrape against the rocks, making a sharp sound.
The skeleton warriors who were climbing up saw the behemoths falling above and the sharp thorns above. Even though they were just undead warriors, they screamed in fear at this moment.
The rolling log was like a comb. Wherever it passed, most of the skeleton warriors clinging to the rock wall disappeared, and only a small part escaped through the gaps between the spikes.
When the rolling log fell four feet above the ground, it was instantly caught by six huge iron chains.
The other end of the chain is hidden in the thick rock wall.
A group of powerful cultivators were quickly turning the winch to quickly recover the rolling logs.
When the rolling log was lifted to about forty feet above the ground, it fell suddenly again.
After just two rounds of attacks, no undead warrior could be seen more than four feet above the rock wall.
At the foot of the pass, there are countless bones smashed into pieces by rolling logs.
Most of the bones are still moving.
Even the long thorns on the rolling logs were hung with the bones of many incomplete skeleton warriors.
The senior officials of Tianjie who were supervising the battle in the distance looked solemn when they saw this scene.
Phantom said coldly: "Zhao Zian is much smarter than Yang Zhentian. The rolling log only fell four feet from the ground. In this way, he can greatly avoid being attacked by the giant warriors.
It seems that it will take some effort to break through the rolling log formation behind the Jade Gate."
