And in addition to the factor of oxygen, there is gravity, and there is atmospheric pressure. People from different planets and different worlds want to enter other worlds, and these things must be taken into account, and if they go there rashly, they will either die of suffocation and poisoning, or be crushed to death by the difference in air pressure, or ...... Wait a minute.

In short, judging from the method just now, the world on the other side is experienced, and it should not be the first time to invade other worlds!

So the other party should be able to solve various survival problems in different world environments!

"There should be nothing wrong with the air, is the problem the air pressure over here?" Xie Yan said secretly.

Those cyan giant jellyfish just now are probably used to judge the difference in air pressure between the two worlds, and the explosion of the jellyfish means that the air pressure in that world is higher than that in this world! And it's still much higher, which depends on the intensity of the jellyfish explosion.

And this is definitely good news for the world! Because that means that the other party cannot be directly exposed to the general environment here, but at the same time, it is also bad news, the other party will inevitably wear a fairly high-end anti-pressure suit!

Then, the key point of this battle is whether the people on this side can break the opponent's anti-pressure suit, as long as they can make a hole and delay for a certain amount of time, the opponent will definitely die!

As Xie Yan thought, within a few hours, the enemy appeared!

Dressed in copper-colored hard anti-pressure armor and anti-pressure helmets of the same color, they jumped out of the copper-colored gate one by one like dumplings and landed firmly on the ground!

The helmets wrapped around their faces, making it impossible for everyone to recognize the specific appearance of these guys, only that they were all more than two meters tall by eyesight! number, about three hundred people!

"Hit!"

A command rang over the radio, and the soldiers dormant in the tall buildings opened fire! At that moment, the gunfire was like thunder and rain, and tens of thousands of bullets shot out, rubbing dense sparks with the anti-pressure armor of the otherworldly.

After the bullets, rockets fell from the sky, pulling a long tail flame and exploding scorching flames. The fire is imprinted in the eyes of every soldier, and these eyes also witness the incompetence of guns and bullets!

After the smoke of gunpowder, there was not the slightest damage to the anti-pressure suit of the otherworldly!

Even, the firepower in the sky didn't force these otherworlders to take a step back!

At this moment, a feeling called powerlessness quietly crept into the hearts of the soldiers present.

Then, the Otherworlders fought back!

As soon as the bronze gun was raised, cyan streamers flew out of the muzzle of the gun, piercing several walls and hitting the target accurately. A copper-colored grenade was thrown into the building, and when the explosion sounded, cracks appeared up and down the top and bottom of a building more than ten stories high! The personnel inside, I'm afraid there are many bad luck.

"How is this going to be fought?" Ke Yang and the others watched this scene in the command room, in a cold sweat, did they really have to use those things?

"Don't worry, helicopters and tanks haven't gotten on yet, let's fire a few shots first, and then let those snipers try to replace them with depleted uranium shells, and let the mutant squad get ready, these guys are isolated in away battles, and there will always be a time when the bullets run out!" The commander-in-chief spoke.

Several orders were conveyed one after another, and several tanks placed in the park drove over, and the inferior and substandard roads were pressed out of cracks one after another.

The appearance of the tank gave the soldiers a little more hope in their hearts, but it was just ......

"It's too slow......"

Xie Yan, who was watching the battle, was not optimistic about these big guys, the opponent's gun could easily penetrate several walls, and it was estimated that there would be no problem in penetrating the tank armor. Sure enough, when these otherworldly people saw the tank coming, they raised their guns very casually, three bullets, and the driver, gunner, and commander were all killed, leaving a heavy empty shell.

Just when everyone was disappointed and about to fall into despair, a sniper fired from a tall building in the distance, and a bullet ignited smoke and shot his head accurately! This is the first Otherworldly Man to be killed!

"It works!" There was a cheer in the command room, but when Ke Yang asked about the number of depleted uranium shells left, there was a dead silence here.

Counting the ones just now, there are only seventeen rounds in total...... There is no way, this thing is also considered a nuclear weapon, the federal government ordered a ban on its use, and with the unification of the world, this kind of weapons of mass destruction have long become chicken ribs, and they are being destroyed year by year, reducing the number. This time, it was because of the special situation that half a box was transferred from the gun museum, which was already very difficult.

And seventeen rounds, I'm afraid I can't even finish the fraction of others.

"Order them all to shoot, they must make sure that they don't miss a shot, and they must fight for a shot to pierce both! Then implement the plan of dividing and killing to fight and nourish the war! Zhan Lu continued to give orders.

The so-called diversion and killing to feed the war plan, that is, to find a way to disperse these invaders, break them into pieces, and send teams to delay. Then, let those thirteen bronze-level masters wearing bronze-level armor take the opportunity to cut into the battlefield and seize the good weapons and equipment on those otherworldly people to fight and fight.

The plan began to be implemented, and the snipers began to harvest the lives of the otherworldly. And with the seventeen rounds of depleted uranium shells gone, fifteen corpses of otherworldly people were left at the scene!

Then a few buildings suddenly collapsed with a bang, and the flying dust obscured the view of the alien team, and then the large falling boulders smashed near them, cutting the team of three hundred into several parts.

Not only that, but a large number of smoke grenades were launched with stun bombs to interfere with the vision and senses of these otherworldly people. At the same time, the elite team of thirteen people quietly dived into the smoke and began to touch the corpse with the help of a thermal imager.

However, something that no one expected happened, the guns used by these otherworldly people were actually locked! In order to unlock the lock, you must enter a psionic energy that matches the user. In addition, the dagger they carry with them must also go through this certification process before it can be unsheathed, otherwise they will have to wield the holster......

When this matter was reported, the high-level officials were dumbfounded, no one expected that the other party would be able to prevent them!

"I guess I've suffered in this regard!" Xie Yan guessed, after all, this is not the first time that the other party has invaded other worlds, in the previous invasions, there may have been cases where weapons were seized by natives, so such a lock was specially put in place!

"In this way, the so-called plans of the official will be in vain, and then it is estimated that it will be time for the fish to die and the net will be broken, and it will be time to plant mushrooms." Xie Yan had listened to the details of these high-level meetings, so he knew the combat process, "In that case, it's time for me to appear." ”

Some people may ask, what can the bee bomb do if the armor that machine guns and cannons can't penetrate?

In fact, compared to Zhan Lu and others, who can only obtain information through video and verbal reports of on-site soldiers, Xie Yan has a unique advantage, he can not only rely on the strong perspective ability of the eye plant to see the true face of these guys, but also capture those subconscious thoughts through the mind receiver.

Therefore, Xie Yan knew that the anti-pressure suit of these otherworldly people was not really that powerful, and the reason why they had such a strong defense was because there were four bronze-level telekinetic mutants, according to what Xie Jiang told him before, these people belonged to the defense category, shield-type telekinetic power holders!

The rain of guns in the sky can only be resisted with the blessing of their defensive power. So as long as you kill these four, the rest of the Otherworlders don't have to worry!

It's just that these four otherworldly people are tightly protected by their teammates, and it's really not that easy for the swarm to get close to each other unexpectedly!
