The fire in the Rukai Mountains burned for seven days and nights.

After seven days and nights, the fire began to spread towards Longerang Mountain, which was connected to the Rakha Mountains to the north, and the original forests of the Rakha Mountains were burned to pieces.

Myanmar was just a British colony at this time, not a country.

So as long as the British government does not come forward to protest, no one will come to find trouble for Zhong Yi and the Chinese Expeditionary Force for these burnt primitive jungles.

Having said that, those environmentally friendly saints bitches are far from being born at this time.

At this time, the UK was not even at the worst time for air pollution.

So Zhong Yi doesn't have to feel guilty about this at all, in fact, he doesn't.

However, although the primitive jungle of the Rukkai Mountains was burned, the Japanese resistance did not end.

Although the fire that burned seven days and seven nights killed many Japanese devils, more devils survived with the ubiquitous caves in the Rukai Mountains.

These Japanese not only survived the huge fire tenaciously, but also continued to resist with these complex caves like a maze.

The 10 infantry divisions of the 22nd Army encircled and suppressed for three days, with little success.

Not only did they fail to wipe out the Japanese who hid in the cave, but they also suffered heavy casualties.

After hearing the news, Zhong Yi came to Ren'anqiang again.

At this time, the oil field in Ren'anqiang had resumed production.

The acting commander-in-chief of the 22nd Army met Zhong Yi outside the oil field in Ren'anqiang.

"Master." When Han Lin saw Zhong Yi again, he couldn't help but feel a little cramped.

Ten days ago, when Zhong Yi heard about Ma Gui's departure, Han Lin repeatedly assured him that he would wipe out the remnants of the 27th Japanese Army who was hiding in the Rukkai Mountains within ten days.

However, ten days have passed, but the remnants of the 27th Army of the Japanese Army have not been wiped out.

In fact, the four divisions of the 27th Army basically did not suffer much damage.

With the gradual improvement of status and the gradual accumulation of military achievements, Zhong Yi's prestige among Sichuan generals of the Mainland China Leagues such as Han Lin also increased.

Zhong Yi just glanced at him, and Han Lin felt like a thorn on his back.

After staring at Han Lin for three minutes, Zhong Yi said in a deep voice: "The Japanese army hid in the cave, and your 22nd Army has no choice but to do anything to them? Is it?"

Han Lin wiped the cold sweat from his forehead and whispered: "Master, we have invited geologists to visit the Rukhai Mountains on site for investigation. Geologists said that the Rukhai Mountains are a typical karst landform, with many mountains, many caves, and many underground rivers. Moreover, many caves can also be connected through underground rivers. The most important thing is that the terrain in the cave is complex. Such a terrain is a natural barrier for the defense party, and it is extremely difficult to attack it!"

Zhong Yi said: "I'm not stupid enough at all. I know to ask a geologist to investigate."

After pausing, Zhong Yi continued to ask: "So, has the geologist told you how to defeat the enemy?"

"I made a few suggestions, but Beizhi felt that it was not very practical." Han Lin said carefully.

Zhong Yi asked: "What suggestions have geologists put forward? Let's hear it."

Han Lin said: "Geologists suggest that we blow up the entrance to the cave!"

"Blow up the hole?" Zhong Yi said, "Well, this suggestion sounds good, why do you think it's not possible?"

Han Lin whispered: "At the beginning, we thought this method seemed pretty good, and we also tried to blow up a few holes, but after the explosion, we found that the holes in the cave would only explode bigger and bigger, and it would be impossible to block them!"

"What else?" Zhong Yi said, "Have geologists made any other suggestions?"

"There is another suggestion," Han Lin said, "geologists also advised us to set fire in the cave."

"Well, this is also a good way," Zhong Yi said. "Starting fire can deplete the oxygen in the cave. As long as the oxygen is exhausted, the Japanese hiding in the cave will be suffocated to death, which is also very good."

"We tried it too, but it still didn't work." Han Lin said, "Because most caves have multiple exits, fresh air will be constantly replenished, so setting fires will be useless."

"So have you ever thought of another way?" Zhong Yi said, "Clutch the hole directly?"

"We have tried it too." Han Lin smiled bitterly, "It doesn't work either, because you can only use stones to block it. You are half tired when blocking it, but the Japanese can only have a few bundles of explosives to explode the hole again."

"You can only use stones to block it?" Zhong Yi said coldly, "Do you have to use stones to block it?"

"What, don't you use stones?" Han Lin said in surprise, "What should you use? soil?"

"Yes, just use soil." Zhong Yi said coldly, "If you use concrete, you don't believe that you can't kill several caves!"

"Use concrete?" Han Lin's eyes lit up suddenly, then he slapped his forehead suddenly and said in annoyance, "Oh, why didn't we expect it? This method should work!"

"Then hurry up." Zhong Yi said, "Don't drag it down any more."

"Yes!" Han Lin stood at attention and turned around and hurried away.

...

Deep in the Rukai Mountains, there is a cave.

In order to save diesel, the diesel engine in the hole is rarely turned on.

Even if Anda Twenty-three, as the commander of the 27th Army, must also explore and solve all problems in the dark, such as eating and excretion.

The only thing that is thankful is that the temperature in the cave is suitable.

Otherwise, if it was as hot as in the jungle outside, the days would probably be difficult.

Another disadvantage is that if you stay in a cave for a long time, your biological clock will be completely lost and you will be completely unable to distinguish between day and night.

For example, now, if Anda Twenty-three doesn't look at the watch, they won't know whether it's day or night.

Just after he finished his hand, Anda Twenty-three was about to take a nap, but the adjutant, Watson Kuan suddenly came over hurriedly.

"Hello Commander!" Hattori reported gasping for breath, "The Chinese army is here again! It seems that I have thought of some way to deal with us again!"

"What are you doing?" Anda Twenty-three smiled, "The Chinese army has used all the methods they can use, and they have no way to deal with us!"

He paused and said, "Order, all infantry brigades, engineer brigades and baggage brigades are strictly prohibited from attacking! Just guard the pass in the cave!"

Hattori said: "But, Commander, it seems different this time."

"Different." Anda twenty-three frowned, "What's the difference?"

Hattori said: "This time the Chinese army carried a large amount of concrete, and it is pouring concrete at the entrance of the hole. It seems that they are planning to use concrete to seal the entrance of the hole!"

"Nani?" Anda Twenty-san's face changed suddenly.
