The sudden change made everyone re-vigilant.

These realm gates opened very strangely, there was no discipline at all, Wang Xi just glanced at it slightly, and sketched a general top view in his brain, judging from the shape, there was nothing special, not like a rune.

At this time, the doctors in the courtyard were basically treating each other's injuries, and it was the Yin soldiers of each department who were responsible for patrolling around. Seeing this scene, they reacted quickly, quickly formed a formation, and approached the boundary gate.

The boundary gates have nothing to do with each other, and the distribution is not scientific and reasonable, and most of the Yin soldiers are distributed next to the boundary gates, beware of shooting cold arrows from inside again. At the same time, because I don't know which end of this gate will drill out of the enemy, so I have to be careful at both ends.

Wang Xi also carried the knife, and scattered around one of the boundary gates with Xiao Yi and Senior Brother, with a focused expression.

He and Wang Bisi looked at each other for a moment, then let Xiao Yi keep an eye on him, quickly squatted down, and began to make trouble in the three-foot area of the boundary gate.

Because the ground is concrete, it is very hard, unlike the wilderness, and it can quickly dig pits or form muddy swampy terrain, which can effectively affect the movement of the enemy who rushes out. So what Wang Xi did were some very simple trigger-type single attack traps. In short, the power can be large, but the attack range cannot be large, otherwise it is likely to affect yourself.

As he set the trap, he looked up and looked left and right. I found that some of the doctors in the courtyard had also begun to enter the battlefield, each picking a target, taking a vantage point, and doing the same thing as himself.

I just waited for about three or two minutes, but there was still no movement.

The moment of waiting, people's accurate perception of time, is not accurate. Especially now, when the spirit is highly concentrated, people are like a taut string, waiting for a little wind to blow and release that accumulated power.

But what's going on?

Wang Xi reminded his companions around him, telling them to be careful not only to pay attention to the boundary gate they were guarding, but also to be careful about the direction of the opening of the nearby boundary gate.

In fact, he doesn't need to talk about this.

The first to start grabbing the land was the Yin soldiers.

I have already suffered a loss, so naturally I will not be fooled again.

If one gate is surrounded by an opening facing the other gates, they will abandon their stay and choose a safe place to aim with their bows and arrows.

Of course, some of them reacted slowly, and after Wang Xi's reminder, they also quickly looked around and re-stood.

Wang Xi saw that everyone was moving slowly, and turned his eyes to the master again.

I saw that the latter did not enter this area at this time, and was discussing something with Liu Hongyu.

"General Liu! The boundary gate can be entered on both sides, but only one side can be exited! Wang Xi said, and at the same time made an archery action.

Since they don't show their heads on the other side now, and they are so mysterious, then we can shoot them too.

He looked at Wang Xi and nodded silently.

This young man, with a clever brain, knows how to let himself give orders.

Seeing the main general's nod, the Yin soldiers immediately let go of the bowstring in their hands, and then took the bow again.

Anyway, if you can't see the results of the battle, you don't need to aim too precisely, you just need to be responsible for shooting the bow and arrow to the other side of the gate.

After a few rounds of arrow rain, there was finally some movement.

Some gates began to close slowly.

Seeing this, some Yin soldiers couldn't decide whether they should take this opportunity to hurry over, but they were all stopped by their superiors.

This is not the bloody battle of Han'an, it is so alone. And it is said that the three institutes have been able to replicate the technology in its entirety, so there is no need to rush for such a little time.

If the enemy withdraws, don't pay too much attention to it.

So what is this now?

Reverse fire reconnaissance?

Observe the strength of the counterattack of the inner courtyard and the underworld through the boundary gate?

And then I saw that the bow and arrow here can also fly like no money, and I was scared in seconds?

Just after these boundary gates were closed, there were immediately boundary gates that gradually expanded from a small black dot to everyone's vicinity.

Some even appear in front of them out of thin air.

If it weren't for the fact that the process of opening the gate took about ten seconds, which was enough for people to react, maybe some people would have been cut in two by the gate.

Wang Xi shouted waste, and hurriedly asked Xiao Yi to follow the steps of the senior brother, and chose a nearby boundary gate to guard. And he is leaning down again to recover or destroy the trap that was laid earlier.

It seems that if the direction of the enemy's invasion can be changed at will, the practice of placing traps in advance is not so useful.

As long as people change directions, then the previous efforts will be in vain. If you don't do it well, it will become a stumbling block for your side.

I thought so, but everyone's reaction was the same.

After recovering the previous trap, the trap was set up in the new place again.

Great is a little troublesome, a little harder. But as long as it takes effect, it can earn the other party's head.

Fighting a war is never an easy job.

This time, after everyone chose their positions, they didn't wait for Liu Hongyu's order again. The bow and arrow were once again powerful, and they continued to shoot through the gate.

Wang Xi pressed Xiao Yi's head and guarded on both sides of the boundary gate, for fear that those archers would not be on the right head and pierce the arrows on himself.

Feeling the sharp chirps of bows and arrows wrapped in spiritual power from front of you up close is really making people's scalps tingle.

These bows and arrows are all fan-shaped.

In other words, the archers of the Yin soldiers stood in an arc, and they did not shoot arrows straight at the boundary gate.

They thought that the enemy would not be so stupid, and they all stayed in front of the gate.

Therefore, this archery formation was naturally chosen, and the way was strived to cover the other side of the boundary gate with maximum firepower.

But soon, the other party reacted.

Scattered bows and arrows began to come back.

It's just that there are already preparations here, and in front of each small archer team, there are three or four large shield soldiers, erecting strong shields to block the opponent's attack.

The two sides fired a few rounds against each other, and it is difficult to say how the other side suffered casualties, but here, only less than ten Yin soldiers were injured, and none of them died.

Wang Xi secretly said in his heart, don't close it again, otherwise you have to put another mechanism.

In fact, it was exactly what he wanted.

The gates were kept open.

From time to time, one or two bows and arrows will be shot, and then dozens or hundreds of bows and arrows will be shot back.

After about ten minutes, some of the gates seemed to have begun to mute and no longer moved, just still spinning there.

"Senior brother, throw two fire talismans and blow them up, right?" Wang Xi proposed.

This is the case with the gate they are guarding, no matter how they shoot arrows here, there is no response.

Wang Bisi said: "But you can, but the cost is too high, in fact, the first time we were trapped in the circle of the boundary gate, we had already made the move of attacking the boundary gate." In order to destroy it, it needs to inflict a huge energy bombardment on it in a very short period of time. In other words, only fiery spells with explosive effects, such as fire or thunder, will work. ”

"But I think it's worth it, the talisman is just a dead thing." Wang Xi said.

Wang Bisi shook his head and said, "No, I don't think about this cost. It's the consumption ratio, I ask you, do you feel a big burden when you open a boundary gate? ”

Wang Xi said: "The consumption is not large, if there are supplementary medicines to support spiritual power, as long as my physical strength allows, I even feel that I can open the boundary gate for an afternoon continuously." ”

Speaking of this, he understood what the senior brother meant.

Combined with the current situation, it is likely that the bereaved are consuming their supplies at this time. I don't know there are many enemies on the other side!

"No, it's still too passive. You have to go over and take a look, I have a way, senior brother, you wait a minute. Let everyone do as I do. ”

After Wang Xi finished speaking, he took out his mobile phone, flicked a video request to Xiao Yi, and after the other party connected it, he controlled the mobile phone with a spiritual power rope and floated it through the boundary gate.

In fact, this is not such a high move, Wang Bisi and others can't think of it. It's just that the battle was too tense before, and after a little slowdown, he immediately started to work on other things, and his mind was filled with too many things for a while, and he didn't have the energy to think at all.

Wang Xi is different, he tried it once on Huangquan Road before, and he thought it was easy to use, so he naturally thought about it again.

So, everyone connected to each other's videos, and then floated out of a mobile phone to spy on another world.

Wang Bisi pinched two hands, and suddenly a regular lens and a specially shaped ice cube appeared in his hand.

He held it close to the phone screen and nodded like Zhao Zhuren, who waved his big hand, and a mist floated in the air.

Can you still project like this?!

After thinking about it for a while, Wang Xi understood that this was not something too mysterious, just the most basic junior high school physics.

Suddenly, everyone's eyes were attracted by the "big screen" formed by this water vapor, and when they raised their heads, their faces were full of curiosity.

As Wang Xi's mobile phone rose higher and higher at the other end of the boundary gate, looking down, everyone found that this was a plain, and the grass on the ground was not luxuriant, and the boundary gates scattered everywhere.

Behind some of the gates, it was empty. And some, there are still Yin soldiers scattered in twos and threes, but they can't lead to the bow but can't send it.

Similarly, on both sides of each boundary gate, there were also Yin soldiers ambushing there.

It is estimated that they are also waiting for the people on this side of the courtyard to stretch out their heads and stab.

More and more mobile phones passed through the boundary gate, and these Yin soldiers in charge of the ambush noticed the abnormality, but they all looked up, looking a little sluggish.

After a few seconds, an enemy general gave the order to defend himself.

Wang Xi guessed right! There really aren't many enemies on the other side!

At the same time, the other party also miscalculated.

I thought these phones were some kind of lethal novelty.

So the Yin soldiers raised their shields one after another, trying to protect themselves.

One shield was obviously not enough, so many Yin soldiers began to gather together spontaneously, forming a small shield array, which looked like one small turtle after another, lying there motionless.

Wang Bisi arranged there, and whoever clicked on it would put the improvised projector on his mobile phone and observe it from all directions, so that Zhao Zhuren and Liu Hongyu could make decisions.

After looking at it for a while, Zhao Zhuren marked out a few boundary gates, put his two fingers together to form a sword technique, and swung forward firmly.

The physician in front of these gates immediately understood, took out the thunder golden talisman, activated it and attached it to the spiritual power bow and arrow of the Yin soldier, adjusted the direction of the latter's aim, and then gave a thumbs up.

I really don't know what is going on with these Yin soldiers who live in different eras, but they can all understand the meaning of this gesture, as soon as the hand is released, dozens of bows and arrows are like meteors, with a variety of golden runes that can produce explosive effects, flying towards several boundary gates, and the tail of the arrow causes bursts of spiritual power fluctuations, dragging out colorful paths. It's like a laser gun in a science fiction movie, fleeting.

This time it is easier to observe the results.

These "spiritual rockets" suddenly roared out from the other end of the boundary gate, and no one could react, so they hit their targets one after another and exploded.

Because the attack was very targeted, it was very fruitful.

Several enemy troops were all annihilated, but because they were Yin soldiers, they couldn't see the corpses, if they hadn't known the existence of the other party in advance, and now that they looked at it, they thought that the attacks had all failed and hit a place where no one was.

Although the Yin soldiers did not understand the principle of this projector, it did not prevent them from understanding what was happening at the moment. Seeing that dozens of enemy soldiers were killed at once, there was an instant burst of cheers. Compared to the silent courtyard, it doesn't seem stable at all

Liu Hongyu doesn't seem to think there's anything wrong with this, the ancient army, cheering for victory - even a very small victory, it should be encouraged, it is good for morale.

It's not that the courtyard doesn't pay attention to this, but they, who have always paid attention to efficiency and practicality, saw that such an attack was so convenient, so they immediately began to continue searching for targets.

This time, there is no need for Zhao Zhuren to command.

Everyone is completely free to fire, and as long as they feel that there is value in attacking, they can cooperate with the Yin soldiers beside them.

For example, there is only one Yin soldier on the other side of the boundary gate, and the physician there will help him aim, and he doesn't even need a charm.

If the enemy is on three, then just bring the talisman over and blast him again.

Later, Liu Hongyu's subordinates had fully mastered this skill and did not need help at all. After the attack, he put his head to the side and glanced at the screen of his mobile phone to see what other targets were worth hitting on the other side of the boundary gate that his team was responsible for.

In the case of this information asymmetry, the killing efficiency suddenly increases a lot. In less than a moment, all the targets that could be killed were eliminated, leaving only those who were still ambushed on both sides of the gate.

There are hundreds of realm gates here, so on the entire battlefield, the total number of Yin soldiers ambushed by the enemy is only four or five hundred.

In this case, if you attack strongly, you will definitely be able to quickly pass through the gate, gain a firm foothold, and build a defensive position.

And with the existence of Wang Xi and Xiaoyi, they are not afraid of being cut off at all.

Even if someone closes the gate, you can open it again.

Liu Hongyu probably also thought of this, and raised his hand.

All the Yin soldiers looked at him, just waiting for the hand to wave down.

"General Liu, wait a minute!" Wang Xi suddenly shouted.

Liu Hongyu said: "I can't care so much!" If the way of heaven wants to split Lao Tzu, then come and split! ”

"It's not! Not this one! Look, master! Wang Xi said as he projected the picture onto the water vapor.

Under his adjustment, everyone found that shocking blood stains could be seen on the ground in several places!

The opposite side is full of Yin soldiers, where did the blood come from!?
