According to historical records, the Tang army's losses in the Battle of Shibao City were extremely heavy, reportedly as high as tens of thousands.

Of course, Li Yunze couldn't just watch tens of thousands of Tang troops die in battle, so he equipped the army with the best equipment.

At the same time, they chose to conduct a surprise attack before the Tibetan reinforcements arrived in large numbers.

After all, the environment near Stone Castle is very desolate, and it is impossible to station a large army all year round. Before reinforcements arrived, there were only a few thousand defenders stationed here.

Once the Tibetan reinforcements arrive, it will be an endless war of attrition.

What was consumed was the lives of the elite Tang army!

After Li Siye selected his troops and horses, he hurriedly sent out his troops.

After ten days of forced march, with more than one-tenth of the troops lost, we finally arrived at the foot of the Stone Castle.

Stone Castle is located in a high mountain canyon, with a drop of hundreds of meters.

There is a cliff on one side and a cliff on the other, so you can only move forward along a diagonal upward path.

The road is very narrow and can only accommodate a dozen people at most.

After careful observation, Li Siye set up camp and slaughtered the cattle and horses that transported supplies to provide extra meals for the sergeants, and distributed all the drinks brought with the army.

After eating and drinking enough, early the next morning, ten people lined up in a row, paving the entire path in a mighty way, and moved forward with difficulty.

The Tibetan defenders were already well prepared. They kept throwing down wooden logs and rolling stones, crashing into the Tang army along the slope.

The Tang troops in the front row were all dead soldiers who took the initiative to sign up and carried heavy shields.

They worked together to form a shield wall, resisting the rolling stones and trees, and threw them one by one into the abyss aside to clear the way.

The defenders released a dense rain of arrows, which really fell like raindrops.

As for the Tang army, all members of the Tang army had iron armor and iron shields, and their defense was as strong as a tortoise shell.

Approaching Shibao City, the sergeants in the front row began to clear obstacles such as deer antlers and horses. At this time, the defenders on the city began to attack like crazy. The Tang army, who was busy removing obstacles, began to suffer increasing casualties.

Li Siye came with a failure-or-benefit attitude, so the ranks of sergeants could only move forward but not retreat.

After the soldiers in the front row were killed in battle, they were pushed into the pits by the back row to fill them.

As the losses increased, the successive Tang armies gradually accumulated to a height close to the city wall.

At this time, Li Siye took off his mask, raised the sharp sword in his hand, and walked towards the city wall with firm steps.

Behind him are a total of two thousand brave Mo Dao hands!
