Under the gaze of more than 100,000 people, the bomb left the wings and pierced from a high altitude into the tiger-head fortress like sharp swords.

The moment the shells entered the ground, the Japanese soldiers in the fortress subconsciously covered their ears.

The ground-blocking warhead did not disappoint the researchers' expectations, and the simplest thing was also pierced into fortifications or rock cracks 15 meters below the surface!

"Bang!"

In the tunnel, a Japanese officer holding a phone looked up at the top of the tunnel.

A warhead drilled out of the concrete and stretched out cracks to the top.

The Japanese officer felt the blood in his body frozen in an instant. For some reason, he shouted to the phone in his hand:

"Run!Run!"

Two shouts left, and the clouds at the top of the tunnel exploded and exploded.

The Japanese officer disappeared from the spot instantly, and along with him were also telephones and weapons and equipment all over his body.

The top of the tunnel seemed to be blown up by thunder, and countless energy was washed in through the gap.

White gel-like substances popped out of the bomb, and these high-energy fuels were like people who were saved from water, sucking the air in the tunnel frantically, and at some point even brought about a tornado-like storm.

The Japanese soldiers in this tunnel felt that their bodies were almost sucked and they couldn't stand firmly.

After sucking the air, the drowning giant began to spit out white flames. The flames were as gorgeous and beautiful as flowers, constantly expanding.

The tunnel has limited space, and the white flames cannot release themselves to their fullest, so they start roaring and roaring!

“Huhhhh……”

The energy and high pressure released when high-energy fuel are burned are compressed by the tunnel again, and the energy and high pressure are like water ripples and constantly impacting back and forth in the tunnel!

After multiple impacts failed, the energy began to spread to both sides of the tunnel!

These shock waves, like water ripples, roared and swept across, tearing everything in the tunnel to pieces!

There are also high pressure and high temperatures after the shock wave.

The Japanese soldiers in the tunnel had just stabilized their bodies from the huge suction force. The next moment they felt difficult to breathe and had dizzy brains. Before they could figure out what was going on, the roaring dragon swallowed them.

The huge energy was like countless hungry monsters rushing around in the tunnel, devouring flesh and blood greedily.

Japanese soldiers cried and shouted at their parents to escape under the pursuit of energy.

However, the cloud explosion bomb was still exploding continuously in the tunnel, with suction tearing and shock waves colliding, and a high-energy chaotic force field inside the fortress.

Some predatory monsters rushed out of the fortress's vents, igniting the trees and dead grass around the vents.

The impact of the vent was even more terrifying than when a volcano erupted. All the Japanese weapons and equipment parts were washed out from the vent and rushed to a height of dozens of meters.

To the soldiers of the Sixth Corps, it seemed that there were countless evil ghosts and dragons fighting inside the Tigerhead Fortress.

They roared against each other, biting each other, filling the narrow underground space and sucking all the air.

The underground tunnels began to collapse, and there were more and more confined spaces.

The energy and shock waves collided in space, and the 20-kilometer-long underground passage was cut into countless segments, with ghosts and howling howlings in their ears. The soldiers of the Japanese Fifth Army looked ferocious.

They opened their mouths wide and used all their strength to breathe the air.

But these are all futile, because all the oxygen in the confined space is consumed by the cloud bomb, and the oxygen content is zero at this moment.

The tunnel collapsed, communication was cut off, and electric lights and guns were no longer there.

The Japanese struggling in the darkness soon disappeared.

But the battle between Youlong and the evil ghost continued until they rushed out of the earth from the entrances of the passage and disappeared into the vast world.

The Hutou Fortress is 12 kilometers wide and 6 kilometers deep. Not every Japanese on the position has been hit, and some people survived by chance.

The Fifth Army Headquarters is located in Zhongmenghu Mountain. Zhongmenghu Mountain is 110 meters high and is more than 300 meters away from the East and West Menghu Mountains!

Because it is the location of the Japanese headquarters, Zhongmenghu Mountain received additional care from the air force, and five ground-based cloud bombs rushed into the 110-meter-high hill.

The headquarters is located inside the mountain and is at least thirty meters away from the surface, which can be said to be an absolutely safe location.

General Hatan Shigeichi stayed in the headquarters with some staff members, and the power and communication were lost almost at the same time.

Then there was the rumbling explosion and the sound of rock cracking and collapse.

Someone lit a match in the dark, but it only burned for a second and then went out.

Hatan Shigeichi felt that breathing began to become difficult, and he stopped the staff from lighting the lamp.

No oxygen!

As the most important command center, the headquarters must have vents, but it has been buried by huge rocks and soil at this moment.

Hatan Shigeichi ordered the staff to pull out the rocks with bare hands, but the collapsed stones are not only huge in size but also in large quantities.

The Lieutenant General began to realize that he was likely to be trapped in this carefully constructed fortification.

Hatan Shigeichi pulled out his command knife in the darkness, and he felt less and less powerful. He was unwilling to die in such humiliation, in this dark corner where no one knew.

But he didn't even have the strength to sway himself.

Finally, he fell into the pile of gravels with the staff officers next to him, and his consciousness fell into eternal darkness.

Outside the Tigerhead Fortress, the plane had stopped dropping bombs, and the whistling sound in the ground was much smaller.

The soldiers of the Sixth Corps flew towards the various positions of the Hutou Fortress under the command of officers at all levels!

Some lucky Japanese were climbing out of the vents and entrances and exits, but they were not carrying weapons and looked frightened.

More than 100,000 soldiers from the Eastern Route Army of the Sixth Corps rushed to the Tigerhead Fortress, which was more than ten kilometers wide!

The lucky Japanese soldier crawled out of the vent and encountered a rain of bullets.

The soldiers rushed to the vent and kept throwing grenades, then began to dump the gasoline, and the flamethrow gun was in place.

“Huhhhh…”

Fires began to ignite one after another at the entrances and exits of the Hutou Fortress.

Some troops dump gasoline in it, while others fill the soil.

Fu Yisheng even saw the engineering troops behind the army responsible for repairing bridges and roads even turned on all bulldozers.

The soldiers were busy with the filling of soil and the setting fires. The surface of the Tigerhead Fortress seemed to have become a huge and chaotic construction site.

"Bang bang bang..."

The fortress is huge, and some Japanese devils on the positions are still resisting stubbornly.

All artillery fire from the 3rd Army opened fire on the Japanese positions that were fighting stubbornly, and it did not subside until the Shandu was leveled.

The battle lasted from noon until sunset. The most important task the soldiers did was to fill the pit and prevent a Japanese from crawling out of the pit.

Let these invaders bury the Chinese workers who built the Tigerhead Fortress.

The Hutou Fortress is less than two kilometers away from the Ussuri River. The Soviet Red Army on the other end of the river can see clearly what is happening on the fortress with a telescope.

They were shocked by the bombshell dropped by the Chinese Air Force and frowned at the strange combat methods of Chinese soldiers.

After watching for a long time, the Soviets finally saw the Chinese's intentions.

They were amazed and full of admiration on their faces.

"It's really ruthless!

But it looks very refreshing and enjoyable!”

Fu Yisheng came to a vent that had just been filled in Anchun Mountain and found that the soil was very thick. He nodded with satisfaction.

The Tigerhead Fortress is the most important of the 17 Japanese military fortresses, and now this fortress has become the tomb of the Japanese themselves.

The battle to attack the fortress has come to an end, and then we will advance with great strides towards the Sanjiang Plain and the Northeast Plain.

The fortresses built by the Japanese elsewhere will become the future patriotic education base.

Because after multiple fortresses were captured, no matter how stupid the Japanese were, they should see that they were just a dead end. Staying in the fortress and holding on.

Fu Yisheng glanced at the other side of the Ussuri River and said lightly:

"If Mao is interested, he can ask them to organize several representatives to come and visit."
