After moving more than 20 miles north from the eastern junction of Yinshan Mountain and the northern junction, most of the main force of the Japanese 3rd Division under the command of Matsui Ishine had already advanced along a narrow river valley in the east-west direction of Yinshan Mountain to the eastern foot of Yinshan Mountain.

However, due to the narrowness of this section of the valley and the fact that it is in spring at this time, the river is flooded frequently, and the water potential of the valley rises a lot.

Therefore, the 17,800,000 Japanese troops under the command of Matsui Ishine, who were advancing through the river valley to the eastern foot of the northeastern mountain range of Yinshan, had not yet reached the eastern foothills of Yinshan through the river valley.

Matsui Ishine stood on the small slope on the side of the river valley, and commanded the devil officers of all departments to urge the devil soldiers to speed up their eastward march through the river valley.

"Fortunately in the midst of misfortune, if Li Yunlong is ambushed on both sides of the river valley, our imperial army that is passing through the river valley will inevitably suffer heavy casualties!" Matsui Shigen secretly rejoiced in his heart, the mountains on both sides of the river valley were stacked and condescending, and only a few thousand soldiers were needed to lock the entrance and exit of the river valley.

Fortunately, Li Yunlong is commanding his main force to besiege Baochang, and it is impossible for there to be soldiers here.

However, Matsui Ishone, who was secretly rejoicing, soon heard Kagesa Zhenzhao running over from behind him, with a solemn expression.

Seeing this, Matsui Shigen suddenly sighed in his heart, couldn't it be that there was some battle report?

"Your Excellency, Baochang Battle Report! Baochang has been lost, and the defenders of the county town have been wiped out! The commander of the Imperial Air Force's fleet that had gone north from Nanyuan Airport to support us had sent us a direct telegram informing us that the smoke of gunfire was filled inside and outside Baochang City, and that a large number of Imperial Army soldiers and Imperial Allied Army soldiers had been killed on the ground. The air support aircraft group and the Baochang command called and contacted, but they couldn't respond, and the situation should be irreparable! ”

Matsui Ishine snatched the urgent telegram sent by Captain Takagi, the flight commander of the Japanese air support group that was going north to support, directly from the air to the headquarters of Matsui Ishine's army, and his brows furrowed for a moment, and the traces of anger were already visible on his face.

"Pa!!

Matsui Ishone slapped the telegram in his hand on a decimal number on the side, his eyes were very angry.

"A bunch of rubbish! Waste, waste! Matsui Shigen roared and scolded, causing several devils not far from the side to look at each other, not knowing what kind of anger Matsui Shigen was angry about! However, several devil staff officers secretly avoided the point, and it was obvious that His Excellency General Matsui was in a very bad mood!

Kagesa Zhenzhao knew that Matsui Ishone's anger was only for a while, and it would soon pass. As for whether the group of wastes mentioned by Matsui Ishine is the Japanese puppet army defenders who are maintained or the devil air fighters supported by the air, Kagesa Zhenzhao is too lazy to guess.

"Your Excellency, the battle in Baochang has stopped. The group of planes from the north air support of Nanyuan Airport arrived in the sky above Baochang and found that there was no trace of the ground battle, and Captain Takagi, who was reconnoitring at a low altitude, observed that there was no trace of the Eighth Route Army troops in Baochang City, indicating that Li Yunlong had already commanded the post department to quickly evacuate Baochang after solving the imperial army and the imperial alliance army troops in Baochang! ”

Matsui Ishone sighed, "Map, drip!" ”

Kage Sazhen Zhao immediately waved his hand, signaling a devil staff officer waiting on the side to immediately take out the military map, and then a devil staff officer and the devil staff officer who took out the map, palmed on both sides, and spread out in front of the two old devils, Kage Sazhen Zhao and Matsui Shigen.

The map is unfolded, and the details of nearby provinces such as Chahar and Rehe are clear at a glance, and the map of hundreds of thousands of miles is very clear, and the geographical locations of villages, towns, and various hills marked on it are clear at a glance.

It is conceivable that in order to invade China, the little devil has already sent people to lurk in various parts of China and draw detailed maps of various places.

Matsui Ishine looked at the map with a frown, "Kagesa-kun, we're still passing through the Yinshan River Valley. has not yet walked out, and at this time, Li Yunlong's department has already withdrawn from Baochang County! Ying Zuojun, where do you think Li Yunlong will attack next? ”

Shadow Zuo Zhenzhao's eyes were solemn, and for the strong combat power of Li Yunlong's department, Shadow Zuo Zhenzhao was already completely convinced and valued.

"It is impossible for the southward railway to attack Zhangbeicheng, and south of Zhangbei is Zhangjiakou, an important nine-sided town that the ancient Chinese dynasty valued. And these towns are all stationed in the empire's heavy troops, Li Yunlong could not attack Zhangbei from Baochang south, and the aviation aircraft group of Nanyuan Airport going north to support the defenders of Baochang did not find any signs of a large force of the Eighth Route Army troops moving south to Zhangbei! ”

After a pause, Ying Zuo Zhenzhao continued: "In this way, Li Yunlong has the possibility of going east to bypass Senjitu and then go south to attack Guojiatun, Fengning, Luanping, and attack the area of Chengde. However, the imperial army could go north from Miyun and Xifengkou to intercept them. It is estimated that Li Yunlong will not go this way. Then only to attack Duolun in the north and attack and advance to the area of Baicha Mountain is the best choice, which can avoid the situation of the heavy troops of the front army in the direction of Beiping going north to intercept it! ”。

"What's more, Baicha Mountain is deep and densely forested, which is suitable for the army to hide and rest!"

When Matsui Shigen heard this, he was silent, and at this time, most of the main force of the Japanese 3rd Division commanded by Matsui Shigen was still some distance away from Li Yunlong's troops, and even if he threw off his feet, it was impossible to catch up with the new regiment of troops commanded by Li Yunlong.

And now, it is not clear whether Li Yunlong's troops went north to attack Duolun.

"Immediately telegraphed to the commander of the aviation flight north of Nanyuan Airport, asking him to follow the railway line north to the line of Duolun to conduct reconnaissance, to see if Li Yunlong's army could be found to attack Duolun in the north. If so, bomb it immediately and report it to me! Hurry up and drop! ”

Ying Zuo Zhenzhao paused and said, "Haiyi, Your Excellency General!" ”。

Kagesa Zhenzhao hurriedly sent someone to send a report, and Matsui Ishine recruited a devil staff officer and said: "Order all troops, speed up the march, quickly pass through the river valley, we will rush towards Duolun, hurry up!" ”。

Matsui felt that if the time could be shortened, at least he would be able to chase after Li Yunlong and attack Li Yunlong when he attacked Duolun.

And Ying Zuo Zhenzhao's analysis should be very good, at least even if he is Li Yunlong, it is estimated that he will choose to attack Duolun and go east to Baicha Mountain to rest, which is conducive to the troops of the new regiment.

If Li Yunlong knew Ying Zuo Zhenzhao's analysis, he had to sigh that the old devil Ying Zuo Zhenzhao still had a hand, and the devil was not a fool!

When Matsui Ishine led his troops out of the river valley, an urgent telegram from Captain Takagi, the flight commander of the devil group heading north from Nanyuan Airport, soon came.

"The reinforcements of two or three squadrons of Duolun who went south to reinforce Baochang encountered Li Yunlong's army on the railway line and were routed, and the aviation flew overhead, but the two armies were unable to drop bombs in a scuffle. The fleet is running out of fuel and can only return quickly! However, it can be confirmed that the more than 700 imperial troops from Duolun to the south encountered the encounter of Li Yunlong's army going north, and I am afraid that they will not be able to win, and Li Yunlong's northern attack on Duolun has been determined! ”

Kagesa Zhenzhao reported to Matsui Ishine in a dejected tone, his tone quite helpless!
