The height and width of the portal are far lower than expected, and the size of the portal directly determines how big a monster can come, for example, the size and width of the portal at the bottom of the sea are more than a kilometer, which can send such a huge monster, but now this portal is only 100 meters high and wide, so the monster that can be sent is more than an order of magnitude smaller than the portal at the bottom of the sea.

The artillery prepared from afar quickly loaded the shells, the planes in the air circled overhead, and the soldiers on the front line entered the fortifications, and the monster began to appear after more than ten seconds of the portal.

It wasn't a huge monster, but a large number of monsters that were less than two meters tall and rushed out quickly, mixed with some taller species, and the number was much less.

The small monster was like a huge dog, crawling on all fours on the ground with extremely fast speed, and it rushed out of the portal almost in the blink of an eye, but the human counterattack was extremely fast, and the various weapons prepared by the front line opened fire the moment the first monster appeared, and bullets and shells of various calibers pulled out the invisible line of fire and tore apart the bodies of countless monsters. There is no feeling that huge monsters are invincible at all, these small monsters seem to have completely abandoned their huge bodies, and they win completely by numbers, when only the weapons on the front line are fired, these monsters do suppress the fire with their bodies in a short time, and they push the battle line forward for hundreds of meters at once, and some of the monsters about 10 meters in it spit out attacks similar to plasma cannons from their mouths, hitting human fire points with extraordinary accuracy, and even destroying some armored vehicles and tanks.

However, as the bombs in the air and the shells of the artillery in the rear fell, the monsters were quickly covered by violent explosions. Although the bombs used are bombshells that are used to deal with giant monsters, not more suitable cluster bombs, a single bomb can still sweep away all the surrounding monsters.

"If that's the case, then the threat is much lower than beta, even without us, the Mi army can rush through the portal." Montana observed the battle situation on the front line and concluded that if these monsters were in the past, then humans would still have some threats, but now that the soldiers have completed the power armoring, the armored vehicles and tanks have also been updated in large numbers, and the firepower is more than a little stronger than before, it is too easy for humans to defeat enemies of this level. But is the strength of the monster, that is, the Kaiju beast, so weak? The question in the girl's heart didn't last long, and a familiar voice came out, and the huge monster still appeared.

Unlike the previous monsters, which were all 300 meters tall at the smallest, this time they appeared about 90 meters tall, which did not reach the previous size. However, these monsters have traces of machinery on their bodies, a strong combination of machinery and biology, and after the appearance of this monster, it has brought pressure to the front line.

This monster can almost ignore ordinary bombs and shells, and even the armor-piercing shells of tanks can only make a shallow hole in the monster's body, and cannot cause fatal damage. Instead, the mechanical parts of these monsters began to work, and bursts of electromagnetic pulses spread around the monsters, causing great interference in the communication of the front line, and the planes in the sky had to stay away from this area to avoid falling, and the power armor on some soldiers also entered protection mode because of the electromagnetic pulse, and the system had to be restarted to avoid being burned by the electromagnetic pulse.

Supporting this gap, the monster quickly rushed forward, the human firepower became much weaker, and it seemed that it could not intercept the impact of the monster, and several black spots falling in the sky covered the body of the large chrysanthemum beast in the blink of an eye, tearing apart the body of the chrysanthemum beast, and a shot directly hit the head, shattering the head directly, the monster's body fell, and the ubiquitous electromagnetic pulse disappeared.

"The strength of this monster is less than half of the strength of the previous 300-meter-level monster, and the electromagnetic cannon can easily kill." It was Yamato who fired the shells, standing in the rear, and Yamato killed this monster in an instant with a salvo, greatly reducing the pressure on the front line. However, relying on this short period of time, a few more open chrysanthemum beasts rushed out, and after rushing out, they attacked forward, and after Yamato fired a few rounds of artillery bombardment, they killed the two monsters, and the defense line of the front line was broken through, and the soldiers of the United States had to abandon the fortifications on the front line.

Fortunately, all the soldiers on the front line have been power-armored, and they have covered each other in the second line of defense, and the nuclear bombs used to wash the floor have also begun to work, and they continue to explode around the monster herd and Kaiju Beast, and the Mi army has once again stabilized the battle line. During this time, a chrysanthemum beast appeared and spread its wings, and it flew into the sky at once, but it was directly knocked down by Iowa in the distance with a super gravity cannon, and there was no second monster that wanted to fly.

But the number of monsters seems to be endless, and the number of the Mi army is limited, in such a short period of time, only less than 20,000 Mi troops were transported to the front line, and many of them are artillery, so even with the help of the bombing of Yamato and the moon in outer space, but the defense line of the front line is still constantly retreating, as the defense line of the Mi army retreats, the Mi army has been unable to complete a completed circular encirclement, and the Mi army located in the direction of Mexico received an order to leave directly by helicopter after giving up the last line of defense, Evacuating to the defense line in the direction of the United States, the Mexicans found that they only had a few thousand troops in their hands to fight soy sauce to form a tattered defense line, although there was no such big monster rushing to the direction of Mexico, but it was also an enemy that Mexico could not defeat.

And all the fire support of the people of the United States is blocking the tide of monsters and monsters rushing in the direction of the United States, and only a small part of the fire support can be divided into the Mexicans, and the Mexican army almost collapsed after contact with the monsters, compared with the United States, Mexico's equipment is too poor, and it cannot be compared with the luxurious United States Army.

"Planb execution!" There was an expected situation, the people of the United States did not intend to consider the ideas of the Mexicans, and the bombers in the sky began to use nuclear bombs in the direction of Mexico, in this era, the nuclear bomb has completely become a conventional weapon, so the nuclear bomb was unceremoniously dropped, and the nuclear bomb covered the monster tide in the direction of Mexico, suppressing the monster tide and continuing to pour towards Mexico.

But this situation didn't last long, and several monsters that could shoot blue light appeared in the portal, spraying towards the sky, and shot down dozens of planes of the Mi Army at once, especially a few bombers, and the suppression of the Mi Army finally could not last.
