Jilong Zongga's deputy was a member of his clan, and when his own city lord brought people to meet the Tang envoys, he felt that something was wrong, because it was a two-day or three-day journey, and he didn't do so.

But an order is an order, he had to obey, but fortunately he soon received a messenger from the Tang people, listening to the Tubo people who were traveling with him, and their party was attacked at the source of the Zang River, and the Zhangxiong people of the brigade were following.

What kind of virtue is the Zhangxiong people, others may not know, but as the main general guarding Gongtang, he is clear, no matter how many people come, it is impossible to defeat the people and horses brought by the city lord.

Therefore, he had no intention of going out of the city to receive him, and it was his duty to stay firmly here, protect the Tang envoys in the city, and wait for information from Luo.

But unexpectedly, on the night when the Tang envoy entered the city, there was an abnormality outside the city, and when he rushed to the city wall with people, there was already chaos outside, and the city was also in chaos.

But he didn't even know who was outside the city, and how many there were!

Gongtang is a mountain city, the city gate is only open to both sides, guarding the road over the mountain, the front is a mountain cliff, forming a natural barrier, when he arrived, the city has been lit with torches, the guards are looking down, he can't help urging repeatedly.

"Where did they come from?"

"I don't know, it's all over the place." A Tibetan defender shone down with a torch, and immediately made him look there.

I saw that on the almost straight mountain wall, there were people crawling everywhere, densely packed all over the surface, and in the darkness behind me, there were countless shadows, moving rapidly, like a group of ants foraging for food.

With a "bang", Zhang Wuxuan vigorously knocked the tip of the ice axe into the soil layer of the mountain wall, lifted his legs, and slowly stepped on the nailed wooden wedge with this force, this wooden wedge is specially built, the front part is a tip, used to drive into the soil layer, and the back half is a supporting surface with grooves, which can be grasped by hand or stepped on.

When he had gained a firm footing, he removed a wooden wedge from his waist and struck it in with great force, and in this way, step by step, the wooden wedge formed an improvised staircase behind him, leading towards the top of the mountain wall.

Beside him was the old man Xu Guangjing, the two were almost parallel, the speed was not slow at all, the same situation, on the entire cliff was the same, in front of the road, all the trained sergeants of the Qiankengshu, and behind them were the Ka people who were good at climbing and jumping in the mountains and forests.

They followed closely behind the mountains where Yang was headed, and when Yang was directly inserted into the source of the Zang River, they followed the Himalayas all the way eastward, bypassing those large and small tribes, and unexpectedly entering the foot of Gongtang City.

After a short rest, as soon as it got dark, they began to attack, not from the mountain road, but chose the most direct and unimaginable direction.

A mountain cliff about a hundred paces high, plus a four-step high city wall, was their chosen target.

This had the advantage of avoiding the defenders' usual defensive system, narrow mountain roads and gates, and the defenders who were on standby, and by the time they spotted the anomaly outside the city, the enemy had already climbed the mountain wall more than 100 paces high, and if it wasn't for a Ka man who had stumbled and fell, the defenders would have had even less time to react.

No plan is perfect, and accidents are part of it, Zhang Wuwei was not alarmed, still doing his own thing, and continued to climb towards the city wall.

"Quick, come on, we're under attack!" After a short period of distraction, the defenders of the Tibetan people immediately reacted and gathered in the direction of the cliff, and at the same time, some of the guards that were originally placed on the front gate were carried by the defenders to this side.

The leading Tang army had to speed up, and there were still about four steps away, and the defenders had already begun to shoot arrows downward, in this case, these arrows naturally had no accuracy, but the crowd below was too dense, and there were always some unlucky guys.

In the last few steps, Zhang Wuxuan walked extremely carefully, and when he straightened up, a feathered arrow smashed into the iron-clad helmet, making a piercing crashing sound.

Stepping on two wooden wedges, he suddenly appeared from outside the city wall, in the surprised eyes of the Tibetan defenders, climbed the city wall with both hands, jumped up, as soon as he stood firm, he untied the Mo knife on his back, swept out a horizontal line, the first to shoot down, was a few torches inserted in the city.

The surroundings suddenly fell into darkness, he immediately jumped off the city wall, the heavy Mo knife waved in the defenders, hitting those unobstructed archers, and immediately set off countless screams and flesh and blood, this time, all the defenders saw clearly the fact that the first to attack was the Tang people!

The deputy was stunned all of a sudden, the envoy of the Tang people was in the city, but their army was silently approaching the city, so the city lord led the troops to respond, was it the other party's strategy?

Judging from the results, this is basically a certainty, and in shame, he constantly urged the defenders, hoping to suppress the Tang people's offensive, because with Zhang Wuprice's actions, more and more Tang people climbed the city wall, and they were followed by Ka people who had never even worn leather armor.

The defenders finally understood what the large black shadow they were seeing, a small number of Tang people, and countless Nibras.

This result disappointed the defenders, who were firmly armed and skilled in their possession of the walls, and under their blows, the defenders began to retreat step by step, while the Ka people behind them climbed up like a tide, gradually outnumbering the defenders.

"Block them, block them, the city lord will return soon!"

The lieutenant was still trying to make amends, but it was only a matter of time before more and more of the enemy came down from the walls and pushed them to the ground, and the city was lost.

What hope is there now? Even if the city lord's team can come back, it is far inferior in numbers, and in desperation, he suddenly thought that in this city, there is also a big man, a messenger from the Tang people.

Regardless of the outcome, the messenger, who had high hopes, had to pay for it, and the deputy gritted his teeth and led a group of men to their residence.

At the head of the city of Gongtang, Zhang Wuyuan and Xu Guangjing glanced at each other, watching countless Ka people rushing over from their side, driving the Tubo people into scattered and fleeing, and it was no longer possible to organize an effective defense.

"This is the third city we've won." Xu Guangjing had a light in his eyes, and he followed the master, which was happy.

"You're mistaken, it's the fifth."

Zhang Wuxuan corrected lightly.
