Han Yunhua, who realized that something was wrong, sent a combat team to infiltrate Lulong County that night to inquire about the news, and at the same time sent more than a dozen teams to listen to the devil's phone calls along strategic points such as railway lines and traffic stations.

The combat team that infiltrated Lulong that night sent back a message saying that they had infiltrated the military police headquarters in Lulong County that night, and had also quietly infiltrated the home of Yuan Dafu, chairman of the Lulong County Maintenance Association, and secretly interrogated Yuan Dafu. It was learned that the day before yesterday, the headquarters of the North China Front ordered all garrison units in North China to be notified to closely check the passing merchants and passers-by, and even the troops heading south and north. If anything suspicious is discovered, it will be temporarily detained.

As for what the devil was looking for, they didn't know very well, but they vaguely heard that it was related to the fierce Eighth Route Army unit in the Chahar area.

At the same time, the groups that listened to the devil's phone also heard that the devil's phone repeatedly mentioned Inner Mongolia, Chahar, Han Yunhua and other words. Due to the signal problem, they did not listen to all the calls of the devil very clearly, but according to some words, it can be judged that the ghost should have noticed something, but they don't know what Han Yunhua is doing, and they don't know Han Yunhua's current location.

The judgment of Han Yunhua and others is still very accurate, Terauchi Shouichi received a secret telegram from Sakura, and learned that Han Yunhua, the soul of the Inner Mongolia Military Region of the Eighth Route Army, had not appeared for more than ten days, and even the guards (saber special operations brigade) that he had been with him had disappeared, Sakura judged that Han Yunhua was probably not in the Chahar region now, and this was a favorable time for the empire to eliminate Han Yunhua's department.

However, being bled by Han Yunhua several times in a row made Terauchi Shouichi very cautious when dealing with Han Yunhua's subordinates, and he easily did not dare to send troops to the Inner Mongolia Military Region. Moreover, it is only uncertain that Han Yunhua may have left the Chahar region, but no one knows what the actual situation is. What's more, the war in Xuzhou is very tight now, although the imperial army has occupied an advantage there, and the hundreds of thousands of central and local troops of the national government of China have been crumbling, but the empire does not occupy an absolute advantage, and the Chinese army can fight back at any time. Therefore, at this time, it is really inappropriate to clash with Han Yunhua, a cunning enemy.

But Terauchi Shouichi was also very uneasy about Han Yunhua's "disappearance", he didn't know if Han Yunhua really had something to do and left his lair temporarily, or if he was lurking on the side looking for loopholes in the rear garrison of the empire, ready to give the empire a hard blow. Therefore, Terauchi Shouyi, who did not know what was going on, ordered the county and township garrisons within the jurisdiction of the North China Front Army and the divisions and brigades of the Imperial Allied Army to immediately enter a state of combat readiness. At the same time, all units were strictly ordered to take strict defense, and many patrols were dispatched to patrol the defense area, and anyone suspected of being suspected could be arrested immediately without approval and await instructions from the front army headquarters.

After analyzing the information obtained, Han Yunhua preliminarily judged that Terauchi Shouichi basically knew that he was not in Daqingshan, but due to the containment of the Battle of Xuzhou, it was impossible for Terauchi Shouichi to send troops to attack the Inner Mongolia Military Region on a large scale, at best, he would send some small troops to find out where Han Yunhua was going. But Han Yunhua also knew that although they were safe for the time being, but now that the devils were alert, it was obviously impossible to think about it when they came.

Moreover, the Battle of Xuzhou is about to come to an end, and hundreds of thousands of troops from the Fifth Theater of the Nationalist Axe will also withdraw from the Xuzhou area one after another, and at that time, the North China Front Army will free up its forces to clean up the mess in the rear, and the Inner Mongolia Military Region will understandably become the primary target of Terauchi Shouichi. Therefore, Han Yunhua must return to the military region as soon as possible to formulate an anti-encirclement and suppression plan and prepare for a larger-scale attack by the devils.

But in the current situation, if you go back the way you came, you are likely to be discovered by the devils, and it will be difficult to get out when the time comes. Therefore, Han Yunhua must come up with a way as soon as possible to return to the military region in the shortest possible time.

Han Yunhua's eyes looked carefully at the map, and he drew a few lines on the map with a ruler pencil, and said after thinking for a while: "It is obviously impossible to return the same way, and the further west you go, the more troops there will be, and the defensive strength will increase accordingly. So we can't go north as originally planned, we should now go north, go through the Rehe into Chahar, and then go back to the military district. ”

For Han Yunhua's decision, the saber special operations brigade was absolutely obedient, and that night Han Yunhua and others secretly attacked the oil arsenal in Lulong County, the devil, and quickly retreated north after snatching a large number of weapons and ammunition and the necessary fuel for cars.

The reason why Han Yunhua wanted to go north was because the northern region was vast and sparsely populated, and the devil's defensive strength was relatively weak. Besides, as long as Han Yunhua's convoy successfully breaks through the blockade line from Chengde to Chifeng and enters the Mongolian Plateau, then the devil will have nothing to do with Han Yunhua and the others.

After the sneak attack on the military oil depot in Lulong County, Han Yunhua ordered the soldiers of the special combat team to rush to Chengde at the maximum speed of the car at all costs, and must rush through the front line of Chengde before the devil reacts, otherwise it will be really dangerous. It's a race against time, and if we have a head start on time, then we'll be fine. But if the devil takes the lead, then this mission is likely to fail. Despite this, Han Yunhua has never worried about the safety of his life and the special combat team, because Han Yunhua believes that even if there are 100,000 devils, it is impossible to leave him and the Saber Special Operations Brigade behind, because the Saber Special Operations Brigade is the first special forces in the world, and the essence of special operations is not something that any general or marshal in this era can understand.

In Han Yunhua's view, the saber may have tasks that cannot be completed, but there will definitely be no situation where the whole army is wiped out after being made of dumplings, because as long as there are mountains and rivers, then there will be a glimmer of life for the special combat personnel.

After a night of galloping, Han Yunhua and the others finally arrived at Pingquan County in the east of Chengde at dawn, as long as they bypassed Chengde City and entered the territory of Longhua or Karaqin Banner, then this mission was basically completed.

Chengde was an important military town in Rehe, where the devils stationed a company of infantry and a mechanized chariot brigade. As the eastern gateway of Chengde, Pingquan not only has two squadrons of elite infantry here, but also sets up several large roadblocks on the traffic arteries here.

Early in the morning, the Wolong Road Card outside Pingquan County seemed very quiet, and the successor puppet army had not yet arrived. After a night of sentry, both the puppet army, which was not very energetic, or the army that had always boasted of its tenacious will, looked very tired.

Suddenly, a somewhat dazzling light woke up more than a dozen puppet soldiers who were dozing off behind the roadcar. At this time, the superb combat quality of the Yue army was vividly reflected, and I saw more than a dozen devil soldiers quickly hide behind sandbags on the side of the roadcar, and set up two heavy machine guns. The puppet army on one side was of inferior quality, and when the convoy led by Han Yunhua had stopped in front of the roadblock, the puppet army entered the combat state, and this speed became a stark contrast to the soldiers next to him.

An infantry lieutenant walked briskly out of the roadcar, raised the red road flag in his hand, and made a sign language for stop inspection.

Han Yunhua walked out of the car at the head of the row, putting white gloves on his hands as he walked, and his temperament looked arrogant and heroic. Walking up to the second lieutenant on duty, Han Yunhua asked in a standard Kyoto accent, "Second lieutenant, is there anything wrong with you stopping us?" You must know that the goods we are transporting are going to Manchukuo urgently, and you can't afford to take that responsibility if you are delayed. I need a reasonable explanation from you now, do you understand? ”

The second lieutenant hurriedly said: "I'm sorry Shaozuo, at this time, His Excellency Commander Terauchi Shouichi personally issued an order to let the troops in the various jurisdictions of the North China Front closely inspect all the vehicles and troops passing by, and we are also acting, I hope Your Excellency Shaozuo can forgive us for our rudeness." ”

Han Yunhua waved his hand and said, "Yo Xi, you are very loyal, very good." I will not punish the Yamato warriors who are loyal to the empire and loyal to His Majesty the Emperor, and now I officially tell you that we are a transport brigade directly under the Kwantung Army Headquarters, and we are carrying out a secret mission personally issued by General Kenkichi Ueten. This is my military ID, you can check it yourself, but the time must be fast, we have to hurry. ”

The second lieutenant of the Yue Army took Han Yunhua's military ID card, looked at it and said: "Thank you very much for your cooperation, you don't need to check it, your military ID card is issued by the Kwantung Army Headquarters, and the check also needs the approval of the Kwantung Army Command." Since you're in a hurry now, let's go first. After speaking, the second lieutenant of the Yue Army commanded several puppet soldiers to open the roadcard and let Han Yunhua and others pass.

Not long after Han Yunhua and the others, the Chengde Garrison Headquarters called to inquire if there had been a group of suspicious pedestrians or vehicles in Pingquan County.

However, when he heard the Chengde Garrison Headquarters' inquiry about the fact that the oil and arsenal in Lulong County had been attacked by unknown forces and that part of the oil, weapons and ammunition had been lost, he suddenly thought of the transport brigade of the "Kwantung Army" that had passed through his defense area in the morning.

Although there was nothing wrong with the military ID card he checked, he clearly sensed that the soldiers in the car were not friendly to him, and even a little hostile. It turned out that he thought that it was because his interception and inspection had made those arrogant young masters of Kyoto unhappy, so he became hostile to him. But in retrospect, this is not a simple disgust or hatred, but a naked hatred. How to say it, it is no different from the eyes of the common people of China looking at them.

With the idea of not seeking merit but seeking no fault, the second lieutenant of the Yue Army reported the news to the Chengde Garrison Headquarters.
