While strengthening the defense of the Ladder Stack, Simalun immediately sent someone to repair the city of Jianmen Pass.

In fact, the restoration of Jianmen Pass is quite simple, because Jianmen Pass is not like other city passes. Jianmen Pass is built between two mountains, with straight and steep mountains and walls standing thousands of feet high. More importantly, the narrowest part of the two mountains is only a few dozen steps.

Although Jianmen Pass was not built in the narrowest place, it was only a hundred steps away. In other words, Jianmen Pass only had the city gate and the city tower, and there were no city walls at all. After repairing, it would naturally be much simpler.

However, the rocks near Jianmen Pass cannot be harvested. There is no way to mine the cliffs that are as steep as sword blades. If the Shu army wants to quarry and repair the city wall, they need to go to the mountain behind Jianmen Pass to mine the stones, but the distance is not too close.

Fortunately, Sima Lun brought a lot of people this time, with a lot of people and a lot of power. Even if each person only picked one stone, there were tens of thousands of yuan in total. It was more than enough to repair a Jianmen Pass.

Simalun personally urged the construction of the city. Jianmen Pass City was the last barrier of the entire Jiange defense line, and there was no need to be missed. To be on the safe side, the stronger the Jianmen Pass City, the better. Simalun not only thickened the city wall, but also raised the top of the city. This city gate tower, which was only about a hundred steps, was built by Simalun, as solid as a rock, towering and majestic, and completely renewed.

Looking at the newly built Guancheng, Sima Lun finally smiled with satisfaction. Now there is a cloud ladder in front of the Jiange defense line and a solid Guancheng behind it. If the Wei army wants to cross, it will be more difficult than climbing to the sky.

After ordering Shizang to stop the attack, Deng Ai did not quickly start the attack again, but repeatedly reconnaissed the Jiange and ordered a detailed map to be drawn. Only when fully prepared could Deng Ai launch a general attack.

The trap camp's tentative attack this time had a good harvest, at least it won two key passes, Cuiyun Lou and Yishitian.

But after the ladder stack was blocked, Deng Ai also realized that it was not easy to attack Jiange. The dangers of Jiange can be said to be greater than any pass or fortress that Deng Ai had fought.

Ordinary passes, such as dangerous passes like Yangping Pass, have no obstacles before attacking the city. The Wei army only needs to attack the city with all its strength.

But Jiange is obviously different from other passes. It takes a lot of effort to remove these strongholds outside Jiange alone.

The Ladder Stack is a mountain climbing stone plank road, composed of more than a thousand steps, which is narrow and steep. The Shu army occupies the commanding heights, while the Wei army can only attack from the top, and it is very difficult to take down the Ladder Stack.

After taking the first-line sky, Shi Zhuan was full of confidence and led his troops to launch round after round of attacks on the Tianlake Stack, but the Tianlake Stack was too narrow, and the large Wei army troops could not be deployed at all, so they could only line up to attack.

The Shu army was condescending, and not only could use bows and arrows, but also stones. The bows and arrows were protected by shields, but the huge rocks that were rolling down were not blocked by shields.

During the first day of the attack, the Wei army lost hundreds of people, but there was no progress. Moreover, on both sides of the ladder stack were deep mountains and canyons, and straight cliffs could not get around. The Wei army could only use a frontal attack.

So after several days of continuous attack, the Wei army was unable to open up the situation and could not get the ladder stack. Although Shi Zhuan's confidence was not shaken, the days of fighting made the soldiers in the trapped camp a little tired. There was no way, Shi Zhuan could only ask for reinforcements.

But Deng Ai did not increase his troops, but instead asked Shi Zhuan to temporarily stop the attack and retreat to the front line to set up camp.

Because Deng Ai’s request this time was to test the defense of the Shu army, and he didn’t prepare to take down Jiange in one breath. If it was so easy, would Jiange still deserve the title of the first level in Shu?

It seems that it is not easy to take down Jiange from the front, and Deng Ai doesn't want to consume his troops here for vain, so Deng Ai began to send people to reconnaise and survey the terrain of Jiange and the surrounding areas, and found local woodcutters and hunters, and asked them if there was a special path to go around the back of Jiange.

But the answers received were disappointing without exception. Jiange was just at the interruption of Dajian Mountain. The east side of Jiange is Dajian Mountain and the west side of Jiange is Xiaojian Mountain. Both mountains are part of Daba Mountain. Jiange is said to have 72 peaks. Each peak is straight and steep, with a wall of thousands of feet high, and looks like a long sword that penetrates straight into the sky. Not to mention humans, even the monkeys who are best at rock climbing will sigh at the peak and be powerless.

Deng Ai couldn't help but frown when he heard this. Under normal circumstances, no matter how dangerous the pass is, it is impossible to block all roads. There are always some hidden paths that can be circulated.

These trails are not accessible to ordinary people, and only those masters who are agile and good at rock climbing and wading can pass.

But even the mountains near Jiange cannot climb even apes. Even the climbing master who is agile, cannot be compared with the apes. Even the path that even apes cannot handle is not enough, so people should not think about it.

The dangerous road of Shu is indeed well-known. The ancient road of Qinling Mountains is already dangerous enough, but there are still many roads that can be passed from south to north. Unexpectedly, after attacking Shu, the Jiange Road was even more difficult and almost unique.

Before marching towards Shuzhong, Deng Ai had already found out that the landslide road in the Micang Road was interrupted and it would take at least several months to repair it. So Deng Ai gave up his plan to march from the Micang Road and instead planned to get Yangping Pass, opened the Jinniu Road, and went down to Baishui Pass to take Jiange.

This road is almost the only official road leading to Hanzhong in Shu, and Jiange has become an obstacle that cannot be avoided on this official road. Even if Deng Ai is resourceful, he has no choice but to face Jiange at this moment.

And even worse news came, that was, Simalun led 20,000 reinforcements to arrive at Jiange, which doubled the defenses of Jiange almost flat and empty, which made it even worse for the already severe situation.

This news was still shot out by the Wei spies who infiltrated the Shu army with arrows. Otherwise, the Wei army's scouts would not be able to get to the Shu army's position at all, and would not have received such important news at all.

It is precisely because this news is very important that the Wei army spies took the risk of exposure to send the news out.

This information is even more precious than gold and provides strong support for Deng Ai's next military operation.
