The battle without strong mouth was not as fierce as expected, Niu Jin's offensive was indeed fierce, but the Wu army did not seem to be so stubbornly defended, and after resisting for a while, it began to rout, giving up the position to the Wei army.

Wuqiangkou is the first barrier of the Huaihe Plain into the Dabie Mountains, the reason why it is called Wuqiangkou, indeed the terrain is not too dangerous, the valley mouth is shaped like a horn, the valley bottom is flat and wide, the highlands on both sides guarded by the Wu army, the slope is also relatively gentle, which is also the reason why Niu Jin can easily succeed.

After taking Wuqiangkou, the Wei army opened the passage to Jiashi.

In fact, Jiashi is not the name of a specific place, this valley passage that stretches for dozens of miles, are called Jiashikou, is the only way to go south to Wancheng, Lujiang County, Wei army wants to take Wancheng, it must occupy Jiashi, break through Shiting.

With Niu Jin as the vanguard, the Wei army quickly advanced to Jiashi with the momentum of breaking through the weak mouth, intending to quickly take Jiashi.

But the difficulty of attacking Jiashi is not comparable to attacking Wuqiangkou, Zhuge Ke has laid down heavy troops in Jiashi, almost all Danyang soldiers. When the Danyang soldiers arrived at Jiashi, they were like fish in water, and they could give full play to their best combat power.

The brave Danyang soldiers did cause great difficulties to the advance of the Wei army, they used the favorable terrain to block the Wei army, and even sometimes appeared behind the Wei army out of nowhere, for the Wei army, this is already a difficult and dangerous place to climb, tired and out of breath, and for the Danyang soldiers, crossing the mountains and mountains is like eating and drinking, easy and comfortable.

Entering Jiashi, the offensive and defensive rhythm of the entire battle was completely controlled by the Wu army, and the Wei army's offensive was greatly restricted, and the Wei army would pay a great price for every step forward, so the war fell into a stalemate for a time.

If it were another commander, in the face of this situation, he would definitely be very anxious, this kind of battle is simply a muddy battle, and if you fall into it, you can't help yourself.

And Sima Yi is much calmer, even if the attack is unfavorable, I have never seen him frowning, Sima Yi is as deep as a pool of autumn water, bottomless.

I'm afraid this is the experience left by Zhuge Liang's war for many years before, what does it mean that the eight winds do not move? I am afraid that only Sima Yi in the whole army can give a corresponding answer.

In the face of an attack that is difficult to progress, Sima Yi does not seem to be in a hurry, what he sees the most every day is the topographic map of Jiashikou, and it is the situation here that he has studied most thoroughly.

Sima Yi is not in a hurry to attack, even if the war is stalemate, he is still as immobile as a mountain, and only where to camp at night every day, how to camp is a difficult problem, Sima Yi must have personally repeatedly seen the camp, as long as he confirms that it is correct, the Wei army will begin to set up camp.

Some people may be very strange that a Changtang commander of the Wei army does not study and worry about how to break the enemy, but instead cares about such trivial things, which is really incomprehensible.

In fact, there is no trivial matter in the army, even if it is this kind of camping and settling down the village, it is also a very important matter, entering the narrow terrain of the mountainous area, the Wei army imagines the same as before, it seems to be very difficult, because in Jiashikou, it is almost impossible to find a relatively flat land.

Then camping on this land has become very cautious, and how to prevent the night attack of the Wu army is the first thing Sima Yi has to consider.

The strength of the Danyang soldiers, Sima Yi must have already learned that this kind of combat ability can not only bring trouble to the Wei army during the day, but also at night, it will never let the Wei army sleep peacefully.

Therefore, the defense of the entire camp is particularly important, and Sima Yi, who is old and serious, does not dare to take it lightly, every time he camps, he must always strictly control it, and never show the slightest flaw, so that the opponent has a chance to take advantage of it.

The attack at the front was blocked, the war dragged on indefinitely, and Sima Yi had no intention of retreating, so the war was consumed like this, and time was consumed day after day.

Now the most troublesome Wei army, is the problem of grain and grass supply, every time the front advances a mile, the logistics supply line will be extended by one mile, the fragile Wei army supply line makes Sima Yi have a headache, Danyang soldiers are already eyeing the side, if there is no effective army to escort grain and grass, it is likely that this supply line will be destroyed by the Wu army.

The army will be chaotic if there is no food, this is a truth that anyone understands, and Zhuge Ke certainly knows better, he retreated step by step in a planned way at Jiashikou and lured the enemy to go deeper, just waiting for an opportunity to give the Wei army a fatal blow.

After thinking about it, Sima Yi handed over the task of escorting grain and grass to the southern army.

After the two battles of Anfengdu and Anfengcheng, the current Zhengnan Army can only be regarded as a remnant at best, and its combat effectiveness is sharply reduced compared with before.

Because of the An Fengdu incident, there were people in the entire army, including the DPRK and China, who had a lot of complaints about Sima Yi, and at this sensitive time, of course, Sima Yi could not play any more conspiracy and put the southern army in a position where the storm was at the cusp.

Idle duties such as escorting grain and grass seem to be quite suitable for the Southern Army.

Now the only team that can maintain high-end combat power in the southern army is probably only the 3,000 cavalry of the Xiao Cavalry Battalion.

The cavalry, on the other hand, was useless in the battle of the stones, and the rugged and bumpy mountain roads completely limited the cavalry's play.

But if it is necessary to escort grain and grass, it seems that this task is very suitable for the cavalry battalion and the southern army.

At present, most of the grain and grass transported from Luoyang are piled up on the wharf of Yiyang, and from Yiyang to Jiashi, there are still two or three hundred miles away, and all need to be transferred by land.

Sima Yi's army and Wang Ling's Shouchun army together had more than 110,000 people, such a huge army, the daily consumption of grain and grass is very huge, two or three hundred miles away, most of the plains, one and half of the mountains, if there is no effective army to escort, it must be very dangerous.

The grain road is almost the lifeline of an army, once lost, it will inevitably make the army in front of it fall into a desperate situation, the army can not be without food for a day, and then the troops with strong combat effectiveness, once they fall into the food shortage, the army's heart will be chaotic, so the grain and grass, it seems to be a simple task, but it is the existence of maintaining the life of the army, Sima Yi thought about it again and again, and finally handed over the task of escorting the grain and grass to the southern army to do.
