Battles between cultivators were different from battles between ordinary people.
Their attacks were thousands of times more brutal than those of ordinary people.
After a night of research, the remaining commanders came up with a plan to attack the city.
They would concentrate their firepower and bombard the city walls one after another.
Zhang Xing reorganized the entire army.
Currently, they were organized into seven Commander Corps.
There were eight commanders and nine vice-commanders.
The extra commander was assigned to manage the logistics.
The seven commanders selected the most powerful soldiers from their ranks: Captaincy, Chiliarch, Centurion, and Squad Leader.
There were also a hundred thousand peak Venerable Stage soldiers.
Each commander personally led a team to bombard the city walls one after another.
The vice-commanders led the other soldiers to cover for them.
The next morning, the seven commanders set off.
The Vermilion Bird Army, who had been waiting for a long time, also began to move nervously.
However, they didn't go out to meet the enemy. Instead, they holed up in the defensive formation.
The defensive formation was like a huge cauldron, trapping Heavenly Cauldron City within.
The seven commanders didn't notice it beforehand.
The defensive formation was only activated when they gathered a hundred thousand soldiers and suddenly swung their battle axes at the city walls.
Rumble!
The Vermilion Bird Army was relieved to see that the defensive formation didn't budge at all.
It was said that this formation could withstand attacks from a Demigod cultivator for ten days to half a month.
It could withstand attacks from dozens of late-stage Sage Stage cultivators for more than ten months.
Of course, this was under the condition that no one was controlling the formation.
There were five million soldiers in Heavenly Cauldron City and another five million behind them.
There were also several thousand Sage Stage cultivators. Under their control, the defensive capabilities of the formation would be increased by several times.
Once the White Tiger Army was exhausted, the Vermilion Bird Army would rush out of the city and beat the crap out of them.
This was also Fu Zheng's strategy.
However, his mission was to keep an eye on Zhang Xing and his guards.
He wouldn't go out of the city to fight until he saw Zhang Xing and the others make a move.
The seven commanders of the White Tiger Army were all dumbfounded.
They didn't expect Heavenly Cauldron City to have a defensive formation.
The seven commanders then led the army to bombard the city walls for an entire day, but the defensive formation was still as stable as ever!
Zhang Xing saw all of this, but he did not make a move, nor did he give any instructions.
Just like that, seven days passed. In the end, the seven commanders were powerless to do anything.
The seven of them knelt in Zhang Xing's camp.
"Lord Marshal Zhang, we are incompetent, please punish us!"
They wanted to show off in front of Zhang Xing and prove that they were not only good at fighting among themselves, but also had the ability to kill their enemies.
However, in front of the defensive formation, they had no confidence at all.
Therefore, they could only ask Zhang Xing for help.
At the same time, they also wanted to see what kind of experience the deputy commander had that they couldn't use as reference.
"Your incompetence is certain. According to military rules, all of you should be beheaded.
But whether I kill you or not, it really doesn't matter.
Just treat this journey as training your combat abilities. "
Zhang Xing would definitely not hold back when teaching them a lesson.
With just a few words, the seven commanders wanted nothing more than to find a hole to hide in.
If they were in the sect, if anyone dared to reprimand them like this, they would jump up and refute.
However, in front of Zhang Xing, they didn't dare to do so.
This young man looked amiable, but he was actually more vicious than anyone else.
The 15 million soldiers of the Vermilion Bird Army had all died at his hands.
After killing Yan Tianci, he actually gave the order not to take prisoners.
It was clear just how vicious and merciless Zhang Xing was!
