The grassland is lined up in two rows, front and back, with so many long crossbows, as long as they emerge, there will be a rain of arrows shooting at the city tower and the city gate, and there are rockets in the rain of arrows.

Chishui Pass had to set up a shield to defend, and tried to go out of the city many times, but failed, but there were fires in several places in the city, so they could only defend the city first.

Later, knowing that the main attack of the Dongli army was Yangcheng, Sha Chongtian knew that he was just being pinned, so he thought about it again and again, and quietly sent a team out of the west gate to help Yangcheng.

However, the next day, Chishui Pass experienced a fierce attack, and Sha Chongtian knew that his strategy of dividing his troops was seen through by the Dongli army, so he had to urgently link up with the people in the city to defend Chishui Pass together.

Although he has not faced the battle head-on for a month, he has also had many dangerous confrontations, and Sha Chongtian, who has the reputation of "Red Fox Sand Shuai", has never fought such an aggrieved battle.

The other party's arrow rain seems to don't want money, as long as the Chishui Pass defenders have signs of rising, there will be a rain of arrows, and after every arrow rain of the Dongli army, they will move forward half a mile or a mile, almost every day.

Behind the Dongli Army, the sappers were rushing to build a checkpoint, and it seemed that they were going to build a Chishui Pass on the grassland.

Standing behind the thick shield on the city tower, Sha Chongtian saw that Baihua Mountain was getting farther and farther away from him, and he breathed a sigh of relief in his heart.

Yun Jingning guessed correctly, although Baihua Mountain is the boundary of Dongli, but because it is such a big mountain outside the pass, it is only used as a natural barrier and has not been paid attention to in previous years.

On the contrary, Sha Chongtian, who has been guarding Chishui Pass for more than 20 years, has long coveted this continuous wild mountain and wants to actually occupy it, so he came up with a plan to let the tiger guard the mountain to expel the Dongli people.

In the past few years, wild boar ridge because of the tiger infested and no one actually dared to step into this deep mountain old forest, although there are still many wild boars, but there are also many become tiger food.

The consequence of the release of the tiger back to the mountain is that the wild environment is changing naturally, and Chishui Pass has not interfered anymore, and the wild hunters in Dongli Mountain can only operate in the area of Shuangxi Ridge.

Lin Ping'an was unlucky, and he met a tiger who happened to come to the periphery of the Wild Boar Ridge, and their hunters happened to come here.

After that, the hunters did not dare to go any further, and the tigers did not seem to have found any good food in this area, so they went back to the depths of the boar ridge.

As for the two tigers that Lin Yanniang and Yun Jingning shot and killed, it is unknown if they were not the two that Sha Chongtian put into the mountain at the beginning.

After the Northern Expeditionary Army entered the Wild Boar Ridge, they also hit one, and they were overjoyed, thinking that this was a good omen for the expedition.

After that, the wild boar ridge was peaceful, and even the wild boars were fleeing for their lives to avoid the danger of possible extinction.

The footsteps of the Northern Expeditionary Army continued to advance, and at least half of the grassland had become Dongli grassland, leaving a large open space at the foot of Baihua Mountain, and then began to build the wall.

Just like the declaration of enclosure, occupying the grassland at the junction with the northern desert, labeling its own mountain range.

It's just that the next three rains have an adverse impact on the Northern Expeditionary Army, after all, they are the main attackers, and they are at a disadvantage at this time, the rockets cannot be used, and the weather is not very good and it is not conducive to a strong attack.

Fortunately, Yangcheng has been broken, the Northern Desert troops have been greatly damaged, and the Red Fox Shashuai is not stubborn, before the loss of Yangcheng, he judged the military situation, and urgently reported the military situation to the Northern Desert Imperial Court, asking for reinforcements.

After several failed raids, he chose to retreat firmly, and it was his duty to guard the pass.

After Yangcheng was captured, 100,000 defenders guarded the aftermath, Yun Jingning only brought 50,000 soldiers to Chishui Pass to support Qin Lei.

Even if you can't get it, you hope to complete the task of building an outpost before the Mid-Autumn Festival.

If the Northern Desert does not meet supply and demand, then continue to fight, and after fighting Yangcheng, there will be Huangcheng and Taicheng in the rear......

Most of the Northern Expeditionary Army were young generals, and only half of the elite soldiers in the Northern Expeditionary Army went out this time, and the rear supply was strong, so there was no pressure on this battle.

It's just that the rain is raging, and it's going to delay their progress.

Fortunately, in the past month, the new Guancheng has been almost built, and some places that have been washed away by the rain can only be repaired urgently.

At this time, Sha Chongtian on the opposite side wanted to attack, Yun Jingning personally went into battle with him for 300 rounds, and a shot stabbed and slashed, almost stabbing Sha Chongtian in the throat.

The veteran was also quick to react, and finally returned to the city with a shoulder injury, and then stopped.

Yun Jingning returned to the camp victoriously, with a look of chagrin: If you smear the poison on the head of the gun, the old thief is afraid that he will die!

If the guard is dead, the morale of the army will inevitably be in chaos, which person with troops does not understand this truth?

He promised his daughter-in-law to take good care of herself, so he was very careful to protect himself.

In the same way, of course, he hopes that the other party will hang up early, so that he can rob the city early and go back to accompany his daughter-in-law.

Seeing that his dignified general actually said such a childish thing, Qin Lei was so angry and funny, and he didn't know what to say about him for a while.

The battlefield was raging and the battle situation was in full swing, but due to the delay in the arrival of reinforcements from the Northern Desert, Yangcheng was still in the middle of the Eastern Li Northern Expeditionary Army.

Sha Chongtian has a wound on his shoulder, and he can't move his long knife, so it is not suitable to fight for the time being, but whenever the rain stops, the rockets of the Northern Expeditionary Army will definitely come with the rain of arrows.

This round of strong attacks did not give Sha Chongtian a chance to breathe at all, and the people in the city had been driven away by Sha Chongtian in this month, allowing them to flee to the rear city.

Now there are only defenders in Chishui Pass, and they are not afraid of any losses, but the strength and arrogance of the Northern Expeditionary Army also make the Chishui defenders angry, and they are shouting to fight to the death and defend the city to the death.

But the army is still panicking in his heart, if he can not die, who wants to die?

In late July, the heavy rain finally stopped, and it was cool for two days, and the temperature soared under the scorching sun, and a heat wave could be felt on the grassland.

The gilded plaque of "Baihuaguan" has been hung on the newly repaired city wall, but the city gate is on the other side of the official road, and only the sentry tower responds to Chishui Pass.

Behind the city wall is the mother wall, there is a hidden soldier hole, there is a rear garrison camp, and then the rear is at the foot of Baihua Mountain.

The camp of the Northern Expeditionary Army was still in front of the city wall, moving forward every day, not much, but the subtleties could make the Chishui Pass guards panic.

Only the tent at the back of the camp was opened every day and moved to the front, and so on and so forth, as if the ground was moving a measuring stick, and in the days when the sand was heavy and healing, even the rain never stopped moving forward.

Now the soldiers are coming to the city.

Chishui Pass had to close the city gate, prepare a large amount of fire oil and rolling stones, and launch a crazy counterattack as long as the Northern Expeditionary Army attacked the city.

But the Northern Expeditionary Army did not attack the city.

Yun Jingning ordered the withdrawal of 50,000 horses stationed in Sanchakou Town and transferred to the siege of Chishui Pass, intending to besiege but not attack, and truly turn this grassland into a grassland for the Northern Expeditionary Army to graze horses.

In the last two days of July, martial law was suddenly lifted in Sanchakou Town, and two days later, the yamen sent people to the villages to deliver the news.
