When Liu Cheng and the others returned with Ikeda Shuren, the remaining five warriors sacrificed another one.

He and Xu Zhi's two German-style submachine guns rang out one after another, and six or seven grenades were thrown out one after another, making the devil's two crooked machine guns dumbfounded, and finally temporarily alleviating the suppressed situation.

Liu Cheng shouted loudly at the remaining four fighters:

"Throw grenades! Then retreat immediately! ”

The four soldiers finally let out a sigh of relief, threw all the grenades on their bodies one after another, followed Liu Cheng and quickly rushed to the door thirty meters away, got into the only intact truck, and roared away.

Shiro Matsui hid behind a bunker and said in a deep voice to the Japanese soldier behind him:

"Let them stop chasing, immediately rearrange the defensive bunker at the gate, quickly count the number of people, and find out the purpose of these people!"

"Hayi!"

Half an hour later, the former Japanese second lieutenant walked into Shiro Matsui's office:

"Report! Matsui Nakasa, the people who infiltrated the cell building opened most of the cell doors and released nearly 300 people on the road, and we killed sixty-seven people, and the rest have all been locked up in their cells! ”

Shiro Matsui nodded:

"That's all?"

Before the Japanese second lieutenant could speak, a Japanese man in a white coat suddenly burst in in a panic, with a cry in his voice:

"Your Excellency Matsui! Oh no, Dr. Ikeda is gone! More than twenty researchers were killed in the underground laboratory! ”

"Nani?! Yaga! ”

Shiro Matsui slammed up from his chair and slammed his right hand on the table.

"Immediately notify the Harbin Police Department and ask them to set up a card to intercept that truck!"

"Hayi!"

After letting the two of them leave their office, Shiro Matsui took a deep breath, picked up the phone on the desk and shook it a few times:

"I'm Shiro Matsui, pick me up Captain Ozawa!"

The person Matsui Shiro was looking for was called Kenji Ozawa, who was the wing commander of the 3rd Wing of the 1st Brigade of the 2nd Division of the Kwantung Army, with the rank of Osa.

The 3rd Wing took over Harbin's defense a year earlier, and the Harbin Police Station and Security Corps were all under the direct management of Kenji Ozawa.

Although Liu Cheng's plan this time was a bit simple and crude, and extremely dangerous, the effect was also immediate.

Before he came, he had already thought of the route of retreat, and after leaving the prison, he did not return via Harbin, but turned around and went straight to Yakeshi, all the way from the grassland back to Chaoyang.

However, despite the non-stop journey along the way, and the fact that the truck ran out of fuel and immediately spent a lot of money to buy horses from the herders it met, it took a full four days to return to Phoenix Mountain.

However, over the course of a week, more than 200 fighters died of illness, and their bodies were cremated and immediately buried.

The death toll on Zhou Zuopeng's side is even higher, exceeding 500.

When Kumasaburo Okamoto learned of this, he immediately reported it to the Kwantung Army Command.

After bringing Ikeda Shuren back, Liu Cheng did not have much effort to "convince" him to treat the wounded together with Qian Lu and Alyosha.

Liu Cheng very politely told Ikeda that if the epidemic could not be effectively controlled within three days, then he would lose the value of continuing to live.

Ikeda had no doubts about Liu's warning.

He watched Xu Zhi kill more than a dozen of his companions at the behest of Liu Cheng, although he now has a certain value, but Qian Lu and Alyosha's medical skills are not bad.

Although they have not yet been able to find a way to control the contagion, they have minimized the spread and fatality rate of the virus.

Even without him, Qian Lu and Alyosha would have been able to find a cure for this infectious disease within half a month.

Therefore, he could only honestly explain the pathological causes and discernment of this virus, and inform Qian Lu of the treatment method they had researched after consuming the lives of hundreds of "big roads", and completely lifted the infectious disease crisis within a week.

Without firing a single shot, and not even seeing the shadow of the enemy, the 39th Division and the independent battalion sacrificed a total of nearly 1,000 soldiers, which made Zhou Zuopeng and Liu Chengdu feel a lot of fire.

Fortunately, Liu Cheng had enough money in his hand, and in the past ten days, the attrition of the independent battalion in the previous battle was reorganized.

And this battle, in which he did not see the enemy at all, also made Liu Cheng see the methods of the Japanese, and he did not want to continue to wait for the opportunity and time to enter the customs on the basis of stability.

He found Zhou Zuopeng, and the two jointly wrote a letter to Song Zheyuan of Chahar seeking cooperation.

And before implementing the next plan, the two decided to take the Okamoto Brigade in Chifeng first and give the Japanese a return gift!

On the other side, after Nakano Huyi took over Rehe, he immediately reorganized the army, removed Lin Guozhong from his post as commander of the 18th Division, and put him under house arrest.

Although he took over the affairs of Rehe, the independent battalion and the remnants of the 39th Division of the uprising were still entrenched in Chaoyang.

If this matter can't be resolved in time, Nakano Torayoshi doesn't dare to guarantee that the chair under his ass will sit firmly.

Therefore, after reorganizing the troops left behind by Zhang Haipeng, he ordered the independent mixed brigade that was originally in his hands and the newly formed 18th Division immediately set off for Chaoyang, wanting to annihilate Zhou Zuopeng's headquarters and independent battalion in one fell swoop!

The 13,000-strong Independent Mixed Brigade and the newly formed 18th Division set out from Chengde on 18 September 1934, carrying 16 75-mm mountain guns, 8 Japanese thin-skinned tanks, 64 mortars, and 108 heavy machine guns.

Although Liu Cheng thought that the Japanese would have the next step, he did not expect that it would be such a large-scale battle.

Putting aside the rest, the size and number of heavy firepower weapons alone already exceed the standard configuration of all puppet army units of the same amount.

Just when Kumasaburo Okamoto, who was wishful thinking, was waiting for Nakano Tiger to encircle and suppress Liu Cheng and Zhou Zuopeng, and he took the opportunity to reap some benefits, he suddenly got the news that the independent battalion and the 39th Division, one left and one right, were approaching Chifeng at the same time.

This frightened Kusaburo Okamoto.

That's a total of nearly 7,000 troops, and if he really fights, his Okamoto brigade, which has just been replenished, is afraid that it will be dealt a heavy blow again, and maybe it will be completely wiped out, and he won't even be able to keep his number.

It was not that the Kwantung Army Headquarters did not take into account the dangerous situation of the Okamoto brigade, but Rehe was too far away from Xinjing, and most of the garrisons in the territory were arranged after Zhang Haipeng took over Rehe;

The Japanese stationed Japanese troops in only two or three places that they considered more important, and the number was very limited.
