Sure enough, Xi immediately frowned and looked over and said:

"How is that possible? The purpose of medical skills is to save lives, and the purpose of improving combat effectiveness is to kill people. These two things are completely opposite. How could the situation you described possibly occur?"

Du Yuqi said:

"Aren't you very interested in my medical skills? And you actively asked me to treat you? Now is a great opportunity for you to learn my medical skills."

Xi said calmly:

“I like to drink milk, do I need to raise a cow at home? I like to eat eggs, do I need to feed a few chickens?”

Xi Ping usually doesn't like to talk much, but Du Yuqi didn't expect that she would either keep silent or speak so sharply. He didn't expect that he would be led astray by her accidentally, so he immediately changed the subject:

"Saving people and killing people is one thing. You are also a veteran. You must know that you can't hit the throat when sparring, right?"

Xi said very straightforwardly:

"Of course, that's the weak spot."

Du Yuqi smiled:

"Yeah, so why is this the key point?"

Xi obviously didn't expect Du Yuqi to ask this question, and said in a daze:

"Because if you get hit you won't be able to breathe."

Du Yuqi snapped his fingers and said:

"Very good. Then the question is, why can hitting the arms or stomach make people breathless, but hitting the chest can?"

Xi couldn't answer this time. Du Yuqi looked at her seriously and said:

"This is just the beginning. The human body is actually more complex and sophisticated than any machine. The premise of the medical skills I am learning is to understand the structure of the human body and the root causes of various physiological reactions such as dizziness, coughing, vomiting, suffocation, etc. In this way, targeted treatment can be carried out. Of course, on the other hand, it can also be simpler and more direct to carry out targeted destruction! Make your attack more effective!"

After listening to Du Yuqi's words, Xi could see that he didn't quite understand, but after thinking about it, he felt that it made sense, so he said readily:

"Okay, if you say so, then I'll help you too."

…

After finally getting two assistants, Du Yuqi finally started working. At this time, there were already four or five wounded people sent over, so Du Yuqi immediately threw himself into the work.

Fortunately, the weather was cold at that time, with temperatures below zero, so the wounds were not easily infected, and the wounded were all warriors with super strong physiques, so Du Yuqi saved a lot of operating procedures, and finally used alchemical potions and magic to finish off, so the wounded were treated very quickly.

During the treatment, Du Yuqi instructed his two assistants while casually asking the injured some seemingly ordinary questions. His expression became more and more serious. When he had a chance to rest in the middle of the treatment, he whispered to Xi beside him;

"It seems that there is a big trouble in the temple."

Xi frowned and said:

"how?"

Du Yuqi said:

"According to the intelligence analysis we have obtained so far, the Minsk Cathedral originally had the advantage of the home barrier, which halved the cost of sacred skills and doubled their effects. However, the advantage of the home barrier is now obviously weakening. It should have been weakened by at least half. This should be the reason why the Bantu tribe suddenly made a move, even forcing their way through those magic traps and arrays at the cost of human lives!"

Xi suddenly said:

"Even if we can't hold on here, as long as we can hold on until dark, we can still retreat with the night vision goggles you brought out."

Du Yuqi smiled bitterly and said:

"It's not difficult for me to escape, but the problem is that if I leave the protection of the cathedral, what will happen to Count Ratness? He will be killed by the opponent's blood curse in a minute. Now the cathedral and I are in a situation where we will suffer together and prosper together... Besides, it will be fine as long as there are more wounded people sent to us. It will be terrible if there are no wounded people sent to us."

At this time, he brought two boxes of food over for the two of them to eat. He happened to hear Du Yuqi say the word "terrible", so he said:

"Why would it be so bad if there were no wounded people sent over?"

Du Yuqi sighed:

"If I were the commander of the Bantu tribe, after confirming that the barrier at the Minsk Cathedral was indeed weakening, I would certainly not send out troops while the barrier was still effective! I would definitely retreat and conserve my strength. Anyway, they are not in a hurry now, so once the barrier disappears, we will attack in full force and end the battle in one go!"

Every time I heard Du Yuqi's words, I was stunned, and then said:

"But how can the other party be sure that this barrier will continue to weaken? What if this is just a temporary situation? Then wouldn't the commander have missed a great opportunity?"

Du Yuqi smiled and said:

"You make a lot of sense, but war cannot be separated from other factors, but should be viewed in combination. Based on the current situation, the invasion of the Minsk Cathedral should be the intention of the mysterious organization. The Bantu tribe is just a party hired by the mysterious organization, and even their internal opinions may not be unified. In this case, the Bantu tribe will definitely put reducing casualties first, and their fighting spirit may not be strong. Therefore, any proposal related to preserving the Bantu tribe's own strength will be able to get the support of the majority."

Sure enough, just as Du Yuqi guessed, the Bantu's offensive began to slowly weaken, and the situation on the battlefield slowly changed from a one-sided attack by the Bantu to a tug-of-war. Then the two sides began to confront each other again, and then entered the stage of cleaning up the battlefield.

Taking this opportunity, Du Yuqi said that he wanted to go to the front line of the battle. With the help of alchemical potions and magic, he had saved at least thirty or forty wounded soldiers, and his voice was increasing day by day. Therefore, his reasonable requests would be met, so he took Xi and others to the battlefield in the west.

…

Soon, a group of people stood on top of the protective wall. It was said that this was the main attack point of the Bantu tribe before. You can see the flat ground in front, extending to a distance of two or three hundred meters. There should have been residential houses nearby, but now there are only ruins left, scattered on the land, with traces of war everywhere, just like it had been bombarded by artillery fire in a modern war. These innocent buildings should have been affected and damaged in the tug-of-war and hand-to-hand combat between the two sides.

At this time, the two sides should have reached an agreement not to attack each other, and they were all carrying the wounded or corpses towards their own headquarters. Du Yuqi roughly counted them and it seemed that the casualties on the Bantu side were more serious.

But strictly speaking, these casualties include a considerable number of transformed warriors and wild beasts raised by Bantu animal trainers. These can be said to be consumables of war and will not cause any serious damage at all.

However, there are no cannon fodders in the Minsk Cathedral - or strictly speaking, all the cannon fodders have died, so the dead are either paladins or mainstays like ascetics. These people are loyal to the cathedral and are the mainstays themselves. It takes a lot of effort for the cathedral to train one.

To be strict, every time a person dies on the temple side, there is one less person who cannot be replaced, which is like a broken bone. It is heartbreaking. Even if the casualty ratio is five to one or even eight to one, it is still a huge loss.

At this time Duize suddenly said:

"You see, something seems to be wrong on the battlefield."

After hearing what he said, everyone looked over immediately. After a long while, Xi finally said:

"You mean, the ice on the ground?"

Duize said:

"That's right! If I remember correctly, there has been no significant precipitation in the past three days, so there is something wrong with the ice on the ground."

After hearing what Duize said, everyone looked down at the ground at the same time.

Sure enough, I saw that the ice on the ground had suddenly presented a very strange shape. From the side close to the ice and snow blockade, a layer of light blue thin ice suddenly spread over, covering the ground tightly. At a glance, it was vast and boundless, as if a layer of light blue ocean was wandering.

On the other hand, most of the ground near the Minsk Cathedral is clean. Even if there is ice, there are only a few pieces occasionally. If you look closely, the two form a very sharp contrast.

After realizing this, Xi first frowned, then pressed his hand lightly on the guardrail next to him, and jumped down from it.

The height of the guardrail is such that an ordinary person would lose their hands and feet if they fell down, but it certainly wouldn't be a problem for Xi. She came to the ground covered with light blue thin ice, walked a few steps on it, frowned, and then uttered two words:

“Home!”

At this time, the rest of the people also followed up, and when they stood on this light blue thin ice, they immediately understood the implication of Xi's words.

It turned out that after they stood on the thin ice, they immediately felt that their feet were extremely slippery. They had to be very careful when walking, otherwise they would slip.

This may seem like a small matter, but in actual combat it is absolutely fatal! Especially for a Paladin wearing plate armor, it is like a steel can. Once he loses his balance and falls, it is extremely difficult to get up. If it happens normally, it is fine. Once such a mistake occurs on the battlefield, it is enough to kill this person a hundred times!

At the same time, even if I was wearing shoes, I could feel the biting cold emanating from the ice on the soles of my feet, and my feet were completely frozen before long.

The priest who led them here was also deeply moved and said:

"Yes, the place covered by this azure barrier is the home ground of the Bantu tribe."

Du Yuqi pondered and said:

"The name of this ice layer is Azure Barrier?"

The priest nodded and said angrily:

"That's right. It is said that this azure barrier was cast by a strong man from the Bantu tribe. It is very powerful. When our people stand on it, not only will the problem you felt before disappear, but their ice resistance will also be reduced invisibly. On the contrary, when the Bantu people stand on it, their movement speed will be significantly improved, and ice spells will have corresponding bonuses. More importantly, hostile barriers cannot coexist. So for every additional meter of the azure barrier covering this side, our sacred barrier will be eroded by one meter!"

As he was speaking, the ice next to him suddenly cracked! This was originally the ruins of a house, and immediately wood, stone and ice chips flew everywhere, hitting people's faces and causing pain.

If it were an ordinary person, the sharp ice chips would fly around and leave a bloody cut on the body, just like a blade. If they hit a fatal part like the eyes or throat, the person might die instantly.

Immediately afterwards, two huge ice worms emerged from the ruins!

The appearance of these two ice worms is similar to that of centipedes, with a flat torso, but without so many legs. The main body surface is an ice-blue shell with long brown hairs growing on both sides of the shell.

They were divided into a large and a small one, and their width was at least two meters. Once they appeared on the ground, although only half of their bodies were sticking out of the ground, they were still as high as two stories. There were two sharp fangs on the mouthparts of their heads. After they appeared, bursts of blue and white ice mist spewed out from them. The priest who led the way didn't have time to react at all, and was directly frozen into a light blue ice sculpture!

Then, another smaller ice worm leaned over and hit the ice sculpture with its head. This is also their hunting method. The large ice worm is a female, responsible for spitting ice mist to freeze the prey.

The reason why male ice worms are smaller is because their shells are thicker, their defense is higher, and their fangs are sharper. If the mist of the female ice worm can freeze the prey, then it will be responsible for smashing the prey. If it just slows down the prey, then it will use its fangs to pierce the enemy and send it flying.

These two ice worms are one male and one female, and they fight one close and one far away, so it can be said that they complement each other very well.

However, at this time, although Xi was thirty meters away from the priest, he was the first to react. He rushed over suddenly and shouted "Duh"!

At this moment, a huge light golden shield appeared. It was the Qigong master's signature skill: Mind Qi Shield! Before this thing broke, no matter how chaotic the world outside was, the people inside would not suffer any harm.
