Without any suspense, the six pontoon bridges extended to the shore almost at the same time, and the Bingzhou army, which had already been ready to go on the shore, rushed onto the pontoon bridge and rushed to the other shore at the first time.

The Sima Army had few garrison troops on the shore, and the shore defense fortifications were extremely simple. It seemed that the Sima Army had voluntarily given up. In fact, Sima Lun and Zhong Hui did voluntarily give up the defense of the river embankment. No matter how many troops were sent to garrison the river embankment, it was not enough for the crossbows to fly stone ships to get stuck in the teeth, so it was better to send fewer troops to symbolically garrison some troops and resist symbolically, which could be considered as consuming the crossbow arrows and stone bombs of the Bingzhou Army.

In short, the Bingzhou army encountered almost no threatening resistance during the landing process. In fact, the crossbow flying stone ship had already been cleared of obstacles, and the Bingzhou army attacked the opposite bank of the Yellow River like a flat ground. The so-called natural danger of the Yellow River is like the same window paper, which can be broken with one stab.

However, Yang Hu did not look any joy on his face, because he knew that the real fierce battle had just begun.

Although Zhong Hui blocked the Yellow River and strictly prohibited any ships from commuting, it still set up checkpoints in many important traffic routes, with the purpose of preventing the Bingzhou Army from doing detailed activities so as to avoid being spying on the Sima Army's military situation.

But facing the Jianjun Office, which was omnipresent in the mercury, even if Zhong Hui was not careful, they could always find a gap to get in. Moreover, the Jianjun Office has long been separated from the scout's reconnaissance method, and they have already completed the infiltration of the Sima military system. Many intelligence, without even the need for the Jianjun Office to take action, were quietly sent out by those who instigated the rebellion.

The building is about to collapse, and many middle-level officials who were unwilling to sink with the Sima family's broken ship had begun to find a way out a few years ago. They intentionally or unintentionally wanted to contact the Bingzhou army, and to send information to the Bingzhou army openly and secretly in exchange for the future after Cao Liang captured the world.

In this regard, the Military Command naturally refused everyone. Every time one person was instigated to rebel, the Sima family's power would have an additional chance of disintegration. Of course, the Military Command would also identify these information again to prevent the false information deliberately leaked from the Sima army. Originally, this spy war and counter-split war were true and false, false, and if you were not careful, you might fall into the trap of the other party.

In recent years, the military commander of Fang Bu has continuously infiltrated the Sima family's forces in all aspects. Fang Bu acted decisively and ruthlessly, often not playing according to common sense, kidnapping, extortion, threatening and extortion. As long as it works, it is useless to do anything.

After continuous development, the military commander has extended its tentacles to various institutions within the Sima Army and spread to every corner. Even if Zhong deliberately blocks all major traffic routes, Sima Army's intelligence will still be continuously transmitted through these instigation and internal responses, which is simply unpredictable.

The Jianjun Office has been operating in various states for many years. It not only has a stable source of intelligence, but also has a secure intelligence transmission channel. Many important intelligence will be delivered to the senior management of the Bingzhou Army in a timely manner, and will not miss the situation at all.

After Yang Hu arrived in Puban, he had already obtained the Sima Army's defense map at Linjin Pass. This defense map would be updated in real time every few days and reported it at any time according to the adjustments made by Sima Army. It can be said that Yang Hu knew the situation on the other side well.

After mastering the Sima Army's defense situation, Yang Hu could naturally dispatch troops more calmly and formulate corresponding offensive strategies.

It is obvious that the Sima army has learned from the failure of the Baimajin Battle and no longer focuses on shore defense, but has increased its efforts in depth defense. They cannot come up with a better way to deal with the crossbow flying stone ship, so they simply selectively gave up the shore defense fortifications and only dispatched a small number of troops to block the embankment. The remaining troops will retreat to a certain safe distance to carry out deep defense.

What needs to be blocked in-depth defense is the powerful cavalry force of the Bingzhou army. The final loss of Baimajin was broken through their last line of defense by the Tunqi camp, which led to the final collapse of the Baima Yellow River defense line. Therefore, both Sima Lun and Zhong Hui regarded the Bingzhou army cavalry as the number one enemy. Therefore, the deployment of the deep area of ​​Jin Pass was basically aimed at the Bingzhou army cavalry.

How to curb the power of the cavalry has always been a headache for the Sima Army, especially in the plains, where cavalry is completely a king. Now the main cavalry of the Sima Army has basically been eliminated by the Bingzhou Army. Therefore, without relying on the natural barriers, the Sima Army could not compete with the Bingzhou Army in the plains. This is probably the main reason why Sima Lun decided to move the capital from Luoyang to Chang'an.

There is no need to worry about Tongguan and Wuguan. The mountains are so steep that they are easy to defend and difficult to attack. The only weakness is probably Pubanjin. The Yellow River defense line is useless. Once a breakthrough is made by the Bingzhou army, the entire Linjin Pass will not be too dangerous and will be unable to stop the attack of the Bingzhou cavalry.

Therefore, digging deep trenches became the only choice for Sima Army, and only by turning the flat ground into ravines can we effectively resist the attack of the Bingzhou cavalry.

Digging trenches is indeed a good idea. The only disadvantage is that they are time-consuming and labor-intensive. Without enough time and manpower, it is impossible to completely complete such a huge project.

Fortunately, the Bingzhou Army delayed the attack for several months, giving Sima Army a full respite. Zhong Hui mobilized 100,000 troops and 200,000 civilians and worked hard for several months, and then he dug dozens of criss-crossing deep trenches in the deep defense zone of Linjin Pass.

Of course this is not useless. At least Yang Hu really felt a headache when he saw the Sima Army's defense map at Linjin Pass for the first time. It seemed that the cavalry would not be able to rely on for the time being to break through the Sima Army's defense line. Infantry would become the main force of this attack, and their mission would be very clear, that is, fill the pit, fill the trenches dug out by Sima Army, and open up a road for cavalry to pass, so that they would have a chance to win.

According to Yang Hu's arrangement, the infantry battalion will serve as the vanguard of attack, the rear of the Changshui Camp, and the central battalion will serve as the reserve team. As for the Xiaoqi Camp and the Guoqi Camp, they can only wait for the troops to stay on the ground and stay still. Only when the infantry troops clear the obstacles and open up the road can they have their place to use.

The infantry battalion is good at fighting for a long time and is the main force of the Bingzhou infantry. They are responsible for the attack tasks, so Yang Hu is naturally the most at ease.
