There are even disciples who can't hold on and exhaust their battle qi, which makes the battle qi fighting array flawed, and they are attacked by the high-ranking undead in the Sui dead army and are injured a little.

Fortunately, with the protection of the heavy "Wuji-I" heavy knight armor, those disciples who were attacked were only knocked off their horses and suffered some shocks, and were slightly eroded by the negative energy carried by the opponent's attack, but there were no casualties.

Bai Yuqi, who knew that he could no longer sit idly by, raised his hand and released a wave of [Missile Storm] to blast away the Sui dead army besieging the disciples, and several [Blasting Missiles] blew up the bone ballista in the field of vision.

Bai Yuqi, who had created a brief buffer for his disciples, ordered them to gather their formation, and with a wave of his hand, he pulled up a towering rock fortress at his feet, protecting everyone in it.

Everyone who had fought fiercely saw that they were safe, and they all sat down, and the high-intensity fierce battle just now made them very tired.

Although battle qi can be attacked and defended, refining battle qi by fusing [arcane particles] and biological energy will greatly consume physical strength.

Even if they have trained themselves through the "Body Forging Technique", they still drain their physical strength by consuming a large amount of battle qi in high-intensity battles, otherwise they will not be caught off guard and have no time to resist when they are attacked by high-level undead.

A group of clerics who were protected by the Infinite Knights were not a big drain, although they occasionally unleashed holy magic to assist in battle.

However, following Bai Yuqi's orders, they knew very well that their main task was not to fight but to assist and heal, so they had been paying attention to saving their limited mana.

Bai Yuqi's requirements for them are:

Before the fighters die, give priority to protecting themselves and not easily fighting in danger.

Only if they are alive can they save more of their companions, and at least keep more than half of their mana as a reserve in case of crisis.

Because as a life-saving healer, once you run out of mana on the battlefield, you will not only become a burden and drag down your companions, but also may kill your comrades and yourself.

This is a test of the on-the-spot judgment ability of these priesthood disciples, when to release buff spells to help their companions, when to save mana to retain the amount of healing, what degree of injury should be treated first, and under what circumstances even if the companion is injured, mana cannot be wasted, these are all things that need to be considered by them.

At this time, it was safe, and the priests were finally able to let go of their hands and feet, some of them treated the Infinite Knights, and some of them released the [Recovery Technique] to quickly restore their strength.

"Don't lie down!"

"The cultivation effect is best at this time!"

And Bai Yuqi, who was guarding the wall of the Eye Fortress, turned around and scolded while releasing the [Ao Neng Missile] to blast away the Sui dead army that surrounded him: "If you recover, you will come up to kill the enemy, and you still expect someone to come to the rescue?"

When the disciples who were originally tired and paralyzed heard this, they gritted their teeth and sat up with their weak bodies, and sat down on the spot to start cultivating.

Soon they were surprised to find that Bai Yuqi, the star monarch's advice, was true!

The so-called breaking and then standing, after completely overdrawing the battle qi in the body, then practice the "Qi Alchemy".

Not only has the speed of absorbing spiritual energy become a little faster, but the speed of refining spiritual energy and refining battle qi has also become a little faster.

Just after such a fierce battle, the improvement they obtained was enough to be worthy of their cultivation for three or five days on weekdays.

While Bai Yuqi was guarding the rock fortress, he observed the tide of undead who had gathered, and from time to time he also raised the fortress to a height that the other party could not climb.

But simply raising the height of the fort did not make much difference.

Because these skeletal forms of the Sui dead army can not only condense bone ladders, but also build towering building cars.

As high as Bai Yuqi raised the fortress, the other party would build the ladder and the building cart as high as possible, even if it was repeatedly destroyed by the [Ao Neng Missile], they persevered around the fortress and built a circle of skeleton building carts.

This made Bai Yuqi a little crying and laughing.

With him guarding, these Sui dead army attacks will definitely not be able to attack.

But he found that as his attacks changed, the Sui Dead Army that was able to stimulate evolved with it.

For example, when he built a fortress, he built a building car.

He used [Arcane Missile] to attack from a distance, and the opponent counterattacked with a ballista, and even made a trebuchet.

Moreover, the ordinary [Arcane Missile] could still explode at the beginning, but the Sui Dead Army quickly evolved a class holding a giant shield to defend.

The harder he hit, the thicker the bone shield of this giant shield soldier, the larger the area, and even a super giant shield like a city gate appeared, and a large number of Sui dead soldiers hid under the shield and approached the fortress, and then erected the giant shield on the city wall and turned it into a slope to climb up.

Bai Yuqi was very suspicious that if he used a few more spell attacks, the other party would have to evolve a high-level class that could resist spell attacks.

And at this time, Bai Yuqi finally discovered why before the Sui army died, why he would attack Anshi City again and again, knowing that he would be sent to death.

Although these undead warriors will lose some soul energy after being "killed", they will gradually evolve by absorbing a large amount of negative energy in this process of continuous death and recovery.

The most obvious is that these Sui dead troops who are besieging the fortress, under the bombardment of Bai Yuqi's [Arcane missiles], a large number of "rotten bone skeletons" were blown to pieces, and even a layer of "bone slope" was piled up under the corner of the fortress.

However, after a period of time, some "gray skeletons" were revived from these piles of broken bones, which significantly increased the number of undead at the level of "ten masters" among the Sui dead army besieging the city.

This is easy to see.

Because when they are scattered throughout the battlefield, each "Ten-Captain" will be accompanied by a squad of "Rotten Skeletons" subordinates.

However, most of these ash skeletons that were recovered from the pile of broken bones were surrounded by the same ash skeletons, which was obviously disproportionate.

You must know that the vast majority of those who besieged them at the beginning were rotten bone skeletons, but the rotten bone skeletons were all gone, and nearly half of them were replaced by gray bone skeletons.

What's even more interesting is that as these Sui Undead Undead warriors evolve, so does the speed at which they recover.

According to observations, after the rotten bone skeleton is shattered, it will probably take an hour to four hours to recover, but the gray bone skeleton only takes a quarter of an hour to about an hour, and the more advanced white bone skeleton can even be revived in a few minutes!

So just dispersing them won't kill them completely, but will cause them to evolve!

Bai Yuqi even saw a general-level white bone skeleton with his own eyes, and after he smashed the skeleton war horse and lower body with a [Ao Neng Missile], he actually used his upper body that could still move to fight himself!
