Entering through the underground entrance of the Tree Fort is the Hall of the Tree Fort.

The hall of the tree castle is opened on two floors, the hall is surrounded by fan-shaped distribution of rooms, the second floor is a shooting position, and the third floor is also a shooting position.

At this time, more than a dozen light and heavy machine guns and at least fifty submachine guns have been erected at the entrances of a dozen rooms around the hall, as well as in the corridors on the second and third floors.

The muzzles of the black holes were all aimed at the underground entrance.

At this time, Long Wenwen was lying on his side on the mound of dirt blocking the underground entrance.

The dozens of cannon fodder who were waiting for the battle stared at Long Wen intently, waiting for his order.

Time passed quietly in the boring waiting, and at a certain moment, Long Wenwen suddenly sat up and gestured to the cannon fodder around him: "Ready!" ”

The dozens of cannon fodder around suddenly came to their senses.

Then, there was the sound of a bolt being pulled.

Long Wen also quickly hid behind a pillar.

After about a minute or two, there was a bang.

With the sound of an explosion, the mound of earth that collapsed and blocked the underground entrance splattered out in a radial pattern.

By the time the smoke from the explosion cleared, the mound of earth that had blocked the underground entrance had been completely emptied, revealing the swarthy underground passage once again.

"Puff ......"

Almost as soon as the tunnel mouth was re-penetrated, several dazzling tongues of fire erupted.

This is the first strike of the Japanese army, preparing to shoot the national army guarding the tunnel entrance in a wave of fire.

It is a pity that the national army has long been on guard against this, and no one is guarding the tunnel entrance, so no one was shot and injured, and only one cannon fodder was injured by a ricochet.

The Japanese fire lasted for more than ten seconds before finally stopping.

Immediately after that, several grenades were thrown in, and they exploded with a bang.

Then, before the smoke from the explosion could clear, more than a dozen Japanese soldiers with bayonets rushed in.

The cannon fodder of the Sichuan Army was waiting for this moment, and Long Wenwen raised the Mauser pistol in his hand is shot: "Fight!" ”

The cannon fodder, who had been waiting for a long time, opened fire at all speeds, and more than a dozen light and heavy machine guns and at least 50 submachine guns fired at the same time, forming a crossfire network with no dead ends in an instant.

Before the dozen or so Japanese soldiers who had just rushed into the hall of the tree fort could react, they had already collapsed in a pool of blood.

The firepower of the Sichuan Legion continued to extend forward, blocking the entrance to the tunnel, and several Japanese soldiers were beaten into a sieve and collapsed at the underground entrance of the tree fort before they could rush out.

Long Wen shouted again: "Flamethrower! Hurry up! ”

Taking advantage of the chaos of the Japanese army in the tunnel, the two flamethrowers quickly stepped forward and fell down outside the entrance.

In the next second, two dazzling tongues of fire spewed into the underground entrance, and a terrible wail and curse immediately sounded in the tunnel.

At 50 meters, the flamethrower is far more lethal than any weapon.

And in a confined space like a tunnel, the lethality of the flamethrower will be multiplied!

In an instant, nearly 100 Japanese soldiers waiting in the tunnel to launch an assault were burned to charcoal! In a confined space like a tunnel, there is no place to escape!

The dragon article yelled again: "Demoman, up! ”

The two Demomen immediately rushed into the tunnel with two bundles of explosives.

Less than ten seconds later, the two Demomen retreated, pulling two cables in their hands.

Exiting the underground entrance, the two Demomen connect the cable to the detonator as fast as they can, and then one, two, three, and press down the detonator at the same time.

In the next second, the ground of the tree castle shook violently.

Immediately afterward, a loud bang came from the underground entrance.

Then, a large amount of gunpowder smoke and soot was sprayed out from the underground entrance.

This time, the underground entrance of the tree fort was completely blocked by the collapsed sand and gravel, and it didn't take ten days and half a month to clean it up at all.

……

Sacrificial flag slope, Sichuan regimental headquarters.

President Chen and Song Xilian said that if they stayed, they really stayed, and they stayed for a week.

After reading the note handed over by Senior Chen, Chief Chen smiled and said to Song Xilian: "Yin Guo, the assault team of the Sichuan Army sent back the news from Shubao, they have just thwarted the Japanese army's counter-assault from the tunnel and re-blocked the tunnel, and within half a month, it is impossible for the Japanese army to reopen the tunnel. ”

Song Xilian said happily: "In this case, the Japanese army can only launch a strong attack from the ground." ”

As soon as Song Xilian's words fell, Nantianmen suddenly squeaked, and then a flare flew up into the air, sprinkling a dazzling strong light, illuminating the entire Nantianmen.

"Really." Chief Chen said with a smile, "The Japanese army is running out of donkey skills. ”

As they spoke, the two of them raised their binoculars at the same time to look at Nantianmen, only to see that the Japanese army had really launched an attack from the ground, but under the cover of the defenders of Shubao and the crossfire from the commanding heights on the Gaoligong Mountains on both sides, they were quickly completely disintegrated, and fled back in a hurry after throwing down dozens of corpses.

Song Xilian said with a smile: "As Jun Zuo said, the Japanese army has run out of donkey skills. ”

"Report!" The adjutant suddenly came in and reported, "Deputy Division Commander Tang of Master Yu is asking to see you outside." ”

"Donkey?" Mr. Chen smiled and said, "This is a peach that wants to pick up the ground." ”

Song Xilian's face darkened, and he said in a deep voice, "Let him in." ”

After a while, Tang Ji walked in with a smile and stood up and saluted: "See the general seat, see the Jun seat." ”

Chief Chen and Chief Yu don't deal with each other, and Tang Ji is Chief Yu's loyal dog, so Chief Chen didn't even bother to do superficial articles, and he didn't even pay attention to Tang Ji.

After all, Song Xilian is the commander-in-chief of the 11th Group Army and Tang Ji's boss.

At that moment, Song Xilian said: "Deputy Division Commander Tang, why don't you defend the Henglan Mountain position, and run to the flag slope?" What if the Japanese army launched a counteroffensive from the ferry? ”

Tang Ji said: "The lowly post is here to ask for war. ”

Although Yu Xiaoqing also wanted to ask for war, he would not come.

Therefore, this kind of thing can only be done by Tang Ji to ask Song Xilian to fight.

"Fight?" Song Xilian said, "Your task as Master Yu is to guard the river defense. ”

Tang Ji said: "General, the Sichuan Army is still a little difficult to deal with the Japanese First Wing with a regiment of soldiers, although the situation of the Sichuan Army is good at the moment, but the water is impermanent, and the soldiers are impermanent. ”

"No one knows what's going to happen next."

"It's better to transfer the main force of our Yu division across the Nu River."

"With the addition of our Yu Division, the Battle of Nantianmen can be quickly resolved."

"After all, compared with the expeditionary force stationed in India, the progress of our western Yunnan expeditionary force has lagged behind greatly, so we should hurry up and not be blocked by the Japanese army at the small Nantianmen."

Song Xilian's brows tightened.

Because what Tang Ji said is also very reasonable.
