As soon as a 20-centimeter-wide gap was opened in the secret door of the outer layer of pine wood and the inner steel plate of the "Beware of the Grenade", two Japanese-style grenades flew out of the secret passage leading to the basement. "Boom" and "Boom" two explosions sounded in the secret passage, and the small space made the shock wave formed after the explosion of the grenade even more powerful, and the three mercenaries who used their bodies to resist the secret door were directly knocked out by the shock wave a few meters away.

Zhao Zhi's reaction was fast, and without waiting for the echo of the explosion to disappear, he stuffed the submachine gun in his hand into the gap of the secret door and swept it. The light bulb in the secret passage had been destroyed by the shock wave, and the five fingers inside were dark and missing, and the only thing that could be clearly seen was the flame burst from Zhao Zhi's submachine gun. "Fire suppression, fire suppression." The explosion of the secret passage has already made the Kwantung Army upstairs aware of the abnormality, and Zhao Zhi at this time can only compete with the Kwantung Army for time, if they are surrounded in this small building, none of them can escape.

Yan Wudao ignored Zhao Zhi's black face, reached out and grabbed Zhao Zhi's belt, and several submachine gunners standing on both sides of the secret door rushed into the secret passage. "Sir, leave these little tasks to us, and when we clean up the bottom, you can go down." Pretending not to see Zhao Zhi's anger, Yan Wudao was determined not to let Zhao Zhi go down the secret passage. "Boom" "Boom" The continuous explosions from the foyer behind him diverted Zhao Zhi's attention, leaving Yan Wudao and a few submachine gunners guarding the secret passage, and Zhao Zhi turned around and went to the foyer with a few mercenaries.

If the layout of the 2nd and 3rd floors is the same as the first floor, then this 3-story small building has more than 40 rooms, Zhao Zhi doesn't know how many Kwantung Army soldiers are in these 40 rooms, but he now knows how many Kwantung Army soldiers rushed down from the 2nd and 3rd floors. Different from the Japanese troops that Zhao Zhi usually used, almost all of the submachine guns used by the Kwantung Army stationed upstairs could fire continuously, which were 100-style submachine guns produced by Japan itself, and Zhao Zhi had seen this kind of Japanese-style submachine gun in the trophies warehouse of the military commandery.

In order not to suffer losses in the melee combat with the soldiers of the Kwantung Army, Zhao Zhi left all the snipers outside, and he now has no machine gun firepower, and the mercenaries use a changed caliber Garand rifle in addition to the submachine gun. The swarming enemies are no longer using stupid and stupid 38 rifles, Zhao Zhi and them are not superior in numbers and weapons, and the only thing they can still rely on is those mercenary special ammunition that has not yet been consumed.

The submachine gun in Zhao Zhi's hand shot out all the remaining bullets in the magazine, and he did not immediately change the magazine, but pulled a smoke bomb from his waist with his backhand and threw it out. "Smoke, smoke" Zhao Zhi shouted twice, this time the smoke bomb thrown out was no longer yellow-green so that Jean looked at it and thought it was a gas bomb, and the smoke canister that fell on the ground was spinning all over the ground, but there was no smoke coming out.

"Yaga, the people of China are all liars, they may not have ammunition." Zhao Zhi shouted quickly, and he spoke Chinese, and the soldiers of the Kwantung Army who came down from the upper floor didn't hear what they were shouting at all. However, many of them saw the smoke canister thrown by Zhao Zhi, and the first reaction of the Kwantung Army soldiers who saw the smoke canister was that the other party threw a grenade over, and then after the smoke canister landed, their other reaction was that it was a poison gas bomb, so the Kwantung Army soldiers crowded on the corner of the 1st and 2nd floors retreated one after another.

The smoke canister also fell to the ground, and everyone above the second floor stepped back and put on gas masks, but the small iron canister dripping and turning on the ground did not move at all, and the second lieutenant of the Kwantung Army, who felt deceived, commanded his team to attack the downstairs again. The mercenaries who had already eaten the antidote and replaced the magazine opened fire again to suppress the enemy's continued downward charge, and the cement stairs were full of stray bullets hitting the wall and then refracting into the whooshing sound of ricocheting, and the soldiers of the Kwantung Army who rushed down the stairs not only had to face Zhao Zhi's accurate shooting, but also those deadly ricocheting bullets that could not figure out the trajectory.

"You all get out of the way, Lao Tzu will meet them." After a long time of hard fighting, Zhao Zhi's ammunition on his side was a little insufficient, especially those submachine gunners who almost didn't have much ammunition left. The sound of gunfire in the building lured in the mercenaries who had stayed outside in the nest recently, two heavy machine guns Liu Ziah outside, and the extra one was carried directly into the foyer by them, and the thick barrel of the black hole was facing the stairs leading upstairs.

Although the rate of fire of the Japanese Type 92 heavy machine gun is not as strong as that of the Thomson submachine gun, it is superior to the large caliber of the bullet and the lethality and destructive power are strong enough. Heavy machine guns opened fire in the small building, and the Kwantung Army soldiers, who were bent on rushing down, retreated upstairs by mistake. Until the two boxes of heavy machine gun bullets are fired, they will not be able to face the heavy machine gun that is constantly spitting bullets, because none of them will be stupid enough to rush out to block the bullets.

Although Zhao Zhi and the others only had one heavy machine gun moved in, if more than a dozen submachine guns were added to make up for the leaks, the Kwantung Army soldiers upstairs would really not be able to get off for a while, and the grenades they threw could not hit the three Thunder mercenaries operating the heavy machine guns at all. "Get out of the way, get out of the way." The mercenary carrying Bazooka squeezed his companion aside and half-crouched down, "boom" and "boom" two explosions, followed by a series of rumbling sounds, and as the overwhelming dust dispersed, the staircase, which was already full of bullet holes, collapsed.

Hearing the shouts of the Kwantung Army upstairs, Zhao Zhi, who had changed the magazine, turned around with his submachine gun and went to the entrance of the secret room leading to the basement. Yan Wudao had already taken people down, only two lightly injured mercenaries were guarding the secret passage, obviously Yan Wudao gave a death order, these two injured mercenaries did not let Zhao Zhi go down the secret passage, forcing Zhao Zhi to stare at him, and they still did not let go.

When Zhao Zhi wanted to go down the secret passage in person again, he was told by the mercenaries who stayed outside that Yan Wudao had used smoke before leading people down the secret passage. The smoke used by Yan Wudao is not a smoke bomb configured by mercenaries, but a kind of smoke specially configured by Yu Dazhi for Yan Wudao.

Yan Wudao used a smoke, Zhao Zhi was relieved, not hearing the sound is the best news, once the sound of gunfire came from the secret passage, it means that Yan Wudao and they are in trouble. "Sir, the news of the wounded brothers has come, they have already met with the partisans, all the wounded brothers are alive, it's just that the Japanese are chasing a little closely, and the explosives and mines planted by the guerrillas have been half destroyed." The communication soldier with the walkie-talkie on his back ran over, which was good news for Zhao Zhi.

Nearly half of Zhao Zhi's 100 mercenaries were killed or wounded, which does not mean that half of them have been killed in battle, and only a dozen of the mercenaries who actually suffered half of the casualties were actually killed in battle, and the rest were light and serious wounded who needed to be treated. It was useless for Zhao Zhi to temporarily entrust those wounded mercenaries to the guerrillas, but it was not a dead end to use a truck full of wounded people to lure away the pursuing Kwantung Army, because Zhao Zhi believed that the guerrillas would definitely meet them at the agreed place.

"Call them back, tell them to go directly to the No. 4 area to call the transport plane to pick them up, don't worry about us, it's not easy to get out here for a while, let's go with a group of people first." As long as the wounded can get out smoothly, Zhao Zhi has a way to take the remaining mercenaries to get rid of the pursuit of the Kwantung Army, as soon as Zhao Zhi's words fell, there was movement in the secret passage behind him, and the two mercenaries who had been guarding outside the secret passage reflexively picked up the submachine gun in their hands, clicked twice, and the bullet was loaded.

"My own person, it's me." Yan Wudao, who had been worried by Zhao Zhi, walked out of the secret passage, followed by those mercenaries who went down to the secret passage with him, but their faces were not very good. "Sir, we were really fooled this time, it's just a place to hoard supplies, there are only a dozen Japanese soldiers guarding supplies, we searched all the places below, we didn't look at two pieces of paper, and there were no Japanese people in white coats to experiment as you said."

"Have those people lived?" Zhao Zhi knew that Yan Wudao had a powerful antidote to smoke in his hands, and some of the mercenaries who went down to the secret passage with him were proficient in Japanese, and they could ask for news from the captives, so Zhao Zhi could be regarded as dying.

"Asked, I have asked all the prisoners who were overturned by the smoke, this has always been a place where the Kwantung Army hoarded supplies, and it was also used to detain some of the anti-Japanese elements they captured, and the troops stationed here were just transferred two days ago, and there was originally only one squad of soldiers stationed here." Yan Wudao lowered his voice and whispered to Zhao Zhi. Thunder really suffered a big loss this time, not to mention that so many materials and resources were mobilized for this operation, even those casualties of mercenaries made it difficult for Yan Wudao to accept.

When he was suddenly ambushed by the Kwantung Army, Zhao Zhi was already sure that he was betrayed to the Kwantung Army by the Soviets, but he still had a trace of fantasy in his heart, and now everything is revealed. "Dead brothers will not die in vain, and wounded brothers will not be injured in vain, I will let the Soviets come up with an explanation, otherwise I will make them regret provoking us." Since he didn't find what he wanted in the secret passage, Zhao Zhi immediately ordered a retreat, and the Kwantung Army troops participating in the pursuit could be killed back at any time, and if they wanted to survive, they had to leave here first.
