Just when the battle was raging in Yanbian, Zhang Kai's 11th and 12th armies were also in a stalemate with the rebels in Heilongjiang, and no one on either side could help anyone.

Zhang Kai was very depressed at this time, the strength of his army and the rebel army were comparable, and the number of losses on both sides was about the same, he was eager to establish credit to show himself when he first joined the Wehrmacht, so that he could gain a foothold in the Wehrmacht in the future, but the rebels were too difficult to bite.

He knew that if it dragged on any longer, they might lose, and the rebels would definitely reinforce it, and he didn't know when the Wehrmacht would arrive, so he could only smoke a suffocating cigarette, thinking about how to inflict heavy damage on the rebels in front of him, and try to delay it until Zhang Zuolin's reinforcements or the Wehrmacht arrived.

The rebel generals on the other side were also very depressed, the Japanese masters had already given them an order to sneak attack Jilin, which was empty in defense, and to kill the defenders in the hinterland of Jilin before the Wehrmacht entered Jilin, but now they were blocked by Zhang Kai's army, and there was no way to do it.

"Boom! Bang! "The whole sky was dark, and the sky was full of black clouds, and occasionally lightning flashed, and the wind blew the trees with a rattle, and you knew at a glance that a storm was coming.

Both sides stopped attacking and defending, and were bracing for the rain, which came at an inopportune time.

The 11th and 12th armies in the northeast hurriedly moved their supplies to a safe place to prevent them from being ruined by the torrential rain, and those cannons and ammunition were covered with oilcloth pieces by piece, because there were not enough hats and raincoats, many soldiers would be drenched in heavy rain.

The rebels on the other side were very worried, they didn't expect it to rain when they attacked, and finally they looked for it and found that the logistics had brought enough shelter to cover their supplies. And there is no place to hide near here, so the rebels can only get drenched in the rain, and they have to watch out for the attack of the Northeast Army.

"Report to the commander, our scouts have found a very favorable information, the rebels don't seem to have the tools to protect them from the rain, only their logistics and supplies have something to cover." Zhang Kai's confidant officer said to Zhang Kai excitedly.

As soon as Zhang Kai heard this, he knew that his opportunity had come, if the rebels attacked in the rain or after the rain, their victory rate would increase to seventy, and it was best to attack after the rain.

"Hahaha, God help me, hurry up and call them to gather, I have something important to discuss." Zhang Kai shouted excitedly, they were referring to the senior officers of the 11th and 12th armies, and it was obvious that Zhang Kai already had his own opinions.

After a while, the senior officers of the 11th and 12th armies arrived, and they thought that the commander had come to them to discuss how to resist the torrential rain, but they did not expect that they were going to attack the rebels, which also made them very confused.

"The rebels don't have the means to shelter from the rain, which means they don't have enough bodies to fight us after the rainstorm, but these are not enough for us to defeat them completely, so I decided to send soldiers with raincoats and hats to attack when the rain comes, and when the rain stops, it's time for us to attack." Zhang Kai said very confidently.

The officers were also very excited when they heard this, they had been in a stalemate with the rebels for long enough, and if they could take this opportunity to take out the rebels, it would undoubtedly be a blessing for them.

Zhang Kai was very excited to discuss with his subordinates how to attack the rebels, and soon they had a battle plan, that is, to attack after an hour of heavy rain, so that their chances of victory would be greater, and as soon as the rain stopped, they immediately launched an attack on the whole army.

In the rebel camp, a group of senior rebel generals were also discussing countermeasures, and the atmosphere at the scene was very dull, and it took a long time for anyone to speak out, obviously because they did not come up with countermeasures. Several high-ranking officers of the rebel army looked very pale and weak, this was the expression brought by long-term opium smoking, they were all relatives of Xu Lanzhou, and they had no military talent at all, and the officers below were very dissatisfied with them.

Xu Lanzhou arranged for these relatives to join the army in order to supervise and control the army, and he did not know anything about the fact that his relatives had been bought by the Japanese with opium, and the officers and their superiors were also afraid of their identities and did not report them, after all, they still had the protection of the Japanese.

"What to discuss, they will kill one by one, what are you afraid of them doing, isn't it just a small rebel!" One of Xu Lanzhou's relatives and officers said disdainfully that in their eyes, Zhang Kai's army, which had defected to the National Defense Army, was a rebel army in the northeast, and even a rebel dared to provoke their Heilongjiang army.

Another relative of Xu Lanzhou, who looked very prestigious, glared fiercely at the officer who had just spoken, and said that he should stop talking. He knew that they had not been recognized by the army, and if it weren't for the fact that these people were afraid of their background, they would have been shot and killed, so he would not interfere in major events as long as they did not involve rebellion or anything like that.

The commander and a senior officer looked at the addict officer with dissatisfaction, and the expression of impatience and disdain on his face was fully revealed, and the officer just wanted to scold, but was glared at again by the officer who had just stared at him and softened.

"This time it was our mistake, we came too quickly, the guide was not perfect, the soldiers had nothing to shelter from the rain, but the rebels on the opposite side had a lot of rain gear, they would definitely take the opportunity to attack. There is no doubt that the combat effectiveness of the soldiers will decline under the blow of the heavy rain, and there may even be a large number of soldiers infected with wind chill, these are all things that we must pay attention to, and a bad one of our Black Dragon Army will be carried here. The rebel commander said worriedly. After Xu Lanzhou defected to Japan, he immediately officially changed the name of the Heilongjiang army to the Black Dragon Army, and the Heilongjiang Army had always called itself the Black Dragon Army, and the Black Dragon Army was obviously better than the Black Army, but now it is just formalized.

"Let the soldiers try to find a way to avoid the rain to avoid typhoid fever, and quickly let the logistics personnel want to cook some hot soup for the soldiers to put in the kettle, so that the soldiers can warm up in the rainstorm and not be stiff and weak." The rebel staff officer added.

The officers below are very bitter in their hearts, there is basically no place to hide from the rain here, so how can the soldiers hide from the rain, now they can only take one step at a time.

"Why don't you attack, let's attack the Mukden rebels while the rainstorm hasn't come yet, consume their bodies, or let them know our madness, I'm sure they won't come back to attack us during the rainstorm." An officer built yì road.

"It's not that it can't be done, but it's not suitable, we don't have rain gear, and the soldiers can't resist the attack of the storm at all after they finish consuming their bodies, and we are now on par with the rebels in Mukden, and we can't completely consume their bodies, I don't build like this." The staff officer just now said.

Half an hour later, the rain struck, and the soldiers shivered in the rain due to the intense wind.

One-third of Zhang Kai's 11th and 12th armies also had no rain gear, so they stood in the rudimentary trenches and stared at the front tightly, after all, they had been taught by Japanese instructors, and their military skills were not far behind, and they still knew it if they obeyed military orders, even if the rain and wind were strong.

At this time, there were already traces of autumn in the northeast, and this rain came inexplicably, and it also caught the two armies off guard, and the battlefield was really changeable.

The artillery of the 11th and 12th armies in the Northeast and the rebels were mostly left over from the Manchu Qing Dynasty, Zhang Kai was not the core army of the Fengtian army, and the new artillery did not flow into his hands, and the situation on the rebel side was similar. Their cannons and shells played little role in rainy days, and heavy rain and strong winds affected artillery performance. Without the support of artillery, it meant that the two sides would have to rely on guns and hand-to-hand combat if they fought in the rain.

Two hours have passed, and the rainstorm has become smaller than at the beginning, and the surrounding vision is not very blurry, but the dark clouds in the sky have dispersed a lot, and it is expected that it will not be long before the rainstorm will stop.

Two-thirds of the Northeast Army was quietly touching the rebel position in raincoats, and the rebel soldiers on the rebel position were shivering at this time, and the hot soup that had been prepared in advance did not have the effect at all, because under the blow of the heavy rain, the hot soup quickly became cold. The soaking wet soldiers were staring nervously at their surroundings while being hit by the torrential rain and strong winds, and their bodies had begun to stiffen, and some soldiers fell on the spot, while others had a fever, and various situations appeared.

The rebel soldiers who were defending in the rudimentary trenches suddenly noticed that something was shaking in front of them, and the tall figure was hardly reminiscent of some animal, and besides, there were no animals here at all, so there was no doubt that it was a soldier of the Northeast Army. The rebel soldier pulled the trigger with his stiff index finger, and a burst of gunfire rang out, followed by a burst of slogans, and all the rebels moved.

"Enemy attack! Enemy attack! Sniper! ”

The rebel officers shouted hoarsely, they had to relay their voices to the soldiers in the rain.

The rain did not drown out the dense gunfire, and the soldiers of the Northeast Army rushed frantically towards the rebel positions, and the rebels were also constantly holding back.

After the heavy rain and strong winds, the rebels' combat strength was significantly reduced, and the rudimentary trenches were crumbling, and there were gaps in many places, but they were quickly filled with the lives of a large number of rebel soldiers.

Wave after wave of the Northeast Army frantically stormed the rebel line, and after an hour the rebel line began to crumble and retreat, and soon the rudimentary trench was occupied by more than half of it, and the rainstorm was already very small.

The state of the rebels was already not good, and after the collapse of the front, many rebel soldiers fled, and the defeat of the rebels was already clear. The next third of the soldiers of the Northeast Army, who did not have rain gear, also arrived, and the whole army went into battle, and soon reached the rebel camp, and those rebel officers had retreated behind their camp with the army.

Just when the Northeast Army thought they had won, a large number of gunfire came from behind the rebels, and there were bursts of rumbling sounds, Zhang Kai's complexion immediately changed, and he immediately ordered a retreat.

The Northeast Army resisted the urge to continue to pursue the rebels and quickly retreated, they also knew that the enemy's reinforcements were coming, and there were quite a few cavalry, no matter how many enemy reinforcements there were, they could not pursue them anymore.

Sure enough, the rebel reinforcements arrived, and a rebel army of about seven or eight thousand cavalry men chased after the Northeast Army at a gallop, but they gave up after only a short time because they were also tired.
