After all, according to previous experience, such a large-scale expedition will take at least three months to prepare, and all aspects required for the expedition need to be carefully prepared, so as to be prepared.

However, the situation of the Jizhou army does not allow Sima Shi to think too much, the situation is pressing, if his own reinforcements can arrive earlier, maybe the situation in the annexation will not deteriorate, and it may even be possible to recover the lost territory.

Therefore, Sima Shi ordered that all the preparations must be completed within a month and march into Jizhou.

Xindu City is already in danger in the face of the siege of the Bingzhou army, and if Sima Shi can't rush to Jizhou as soon as possible, maybe Xindu will really be lost.

Xindu is the most important part of Jizhou's defense system, and if Xindu is really lost, it will definitely be the heaviest blow to Sima Shi.

However, Sima Shi still has a great trust attitude towards Lu Zhao, according to the information provided by Xindu, there are still 70,000 defenders in Xindu, with such a large number of troops, it is obviously not too difficult to hold Xindu, especially Lu Zhao on the table, painfully Chen Chen, fight to the death to defend Xindu City.

Lu Zhaoke is an experienced veteran of the battlefield, he has served as the general of Zhenbei to guard Jizhou, has been more than ten years, the geography of Jizhou, I am afraid that no one will know more than Lu Zhao, Sima Shi's reason is to believe that Lu Zhao will be able to defend Jizhou.

Despite this, Sima Shi still asked as much as possible to make all the preparations before the expedition, and if he could set off early, it would be better.

However, the experience of the battle of Jinzhong that year, before making all preparations, Sima Shi did not dare to send troops easily, after all, Cao Liang is a rather terrible opponent, and the troops that Sima Shi can mobilize this time are already all the mobile forces of Sima Jun, if it really fails again, the great cause of the Sima family, I am afraid it will really be the end of life.

The number of troops dispatched last time is almost the same, and the troops mobilized by Sima Division this time are exactly 170,000, 70,000 cavalry, and 100,000 infantry.

After the transfer order was issued, some ministers expressed concern, indeed, this time Sima Shi sent troops, almost the troops in Luoyang area were evacuated, Luoyang is the capital, if there is a vacuum in Luoyang, it will greatly cause those who intend to rebel against the coveted people, Luoyang is likely to fall into a crisis, so some ministers advised Sima Shi to think twice, and must ensure that Luoyang is safe and sound in the case of mobilizing troops.

However, Sima Shi ignored these exhortations, for Sima Shi, after cleaning up the rebel group of Xiahou Xuan, Li Feng and Zhang Ji, the situation in Luoyang has become stable, as for whether there are still some hostile forces in the DPRK and China, Sima Shi is no longer afraid, after all, these people are much less qualified than Xiahou Xuan Li Feng and Zhang Ji, and Sima Shi is not too worried that they will raise troops to become demons, if someone dares to take the opportunity to jump out and make trouble at this time, Sima Zhao, who stayed in Luoyang, can also kill them with one hand.

At the same time as the army in Luoyang was urgently mobilized, ten pontoon bridges were being built on top of Xiaopingjin, Mengjin and Wushejin.

The Yellow River is a moat, if the 170,000 army crosses the river by ferry, even if all the ferries on the Yellow River are concentrated, it will not be able to cross such a huge army in ten days and a half months, so the way to cross the river by using a pontoon bridge has become the first choice for Sima Jun's to cross the river.

Moreover, Sima Shi ordered that ten of them should be built at a time, so as to ensure that the 170,000 troops who went out to cross the Yellow River without delay and march to Jizhou.

The preparation work took about ten days before it was completed, but compared to the previous pace of dispatching troops, this speed was fast enough.

After the preparations were completed, Sima Shi immediately waved his division north, crossed the Yellow River, and marched towards Jizhou.

But as soon as he arrived in Yecheng, there was an unfortunate news from the north - the letter was lost.

The 170,000 troops who originally planned to attack Xindu fell into hesitation for a while, not knowing whether to advance or retreat, and stayed in Yecheng, hesitating.

When Sima Shi heard the news, he couldn't help but be furious, Xindu has a double city wall, which is extremely strong, and the defenders alone have reached 70,000 people, and there is no reason why he can't hold it for even a month.

In Sima Division's plan for the Jizhou operation, Xindu was an extremely important link, Sima Shi could tolerate the loss of the northern defense line of Jizhou, and allowed Lü Zhao to concentrate the men and horses of other cities in Xindu to implement key defenses, but he would never tolerate the loss of Xindu.

This is not only because Xindu is the state city of Jizhou, but also because Xindu is the only existence on the northern defense line of Jizhou, once Xindu is lost, it will lead to the miscarriage of Sima Division's counteroffensive plan, and the entire Jizhou front will be forced to move south, Yecheng will also directly face the impact of the Bingzhou army, and the situation in the entire Jizhou will take a sharp turn for the worse, and the battle situation is critical.

In Sima Division's counteroffensive plan, sticking to Xindu is an indispensable and important part, the 70,000 soldiers and horses of Xindu will be a nail buried in the north of Jizhou, don't look at the siege of the Bingzhou Army now, you can't get out of the city at all, but when Sima Division's reinforcements arrive, this dead son can be activated in an instant, and the Sima army and the Xindu defenders should join forces inside, and will completely crush the attack of the Bingzhou army and expel Cao Liang from Jizhou.

Then Sima's army will enter the great counteroffensive, although Sima Shi is not fully prepared for the big counteroffensive, but when the opportunity comes, how can Sima Shi easily give up.

Since the defeat of the Battle of Jinzhong, Sima Shi has endured for several years in order to counterattack the plan, as long as the Battle of Jizhou is won, it will be a great opportunity for Sima Zaijun to pursue and recover all the lost territory in one fell swoop.

This will also be the first time that Sima Shi will command an army in the true sense, whether it is to establish the prestige of Sima Division, or to the overall situation of the world, it is a crucial battle, and Sima Shi will never allow it to fail.

Since Sima Shi sat in a high position, he has not yet played, and he has only been behind the scenes to coordinate the overall situation against Wu State twice, but this time the opponent is different, Sima Shi is not enough to defeat such a powerful opponent without personal conquest, so Sima Shi will make up his mind and personally command the army to fight, and this battle will also completely change the general trend.
