Murong Yu stayed in the barracks for about half a month and then returned to Beijing. Before he returned to Beijing, the Northern Expedition army's attack on Yongning mountain was still going on.

On this day, after another failed attack, the soldiers who led the troops came back and couldn't help scolding. The men in the army were quite straightforward. They were extremely unhappy with the sudden emergence of Yougu in Beiliang.

In a word, Gan Cheng is also a man who fights regularly and can afford to be aboveboard. At least, as Murong yuan's opponent, he will not be ashamed of Murong yuan. However, at this time, a Yougu suddenly appeared. With Gan Cheng, the whole army of Beiliang became very strange.

A group of people sat in the tent of the meeting, and were upset that they had attacked Yongning mountain for several days without getting anything.

Su Yunchu and Murong yuan sat at the beginning, looked at the people below and said, "gentlemen, I can't lift up strength?"

Su Yunchu's words seemed relaxed, and he didn't blame the soldiers.

People also understood Princess Jing's temperament. At this moment, listening to Su Yunchu's words, someone sighed, "princess, don't say that Yongning mountain, such a large land, has been taken advantage by Gan Cheng. Now, let's attack. Yongning mountain is easy to defend but difficult to attack. This... Alas!"

A general sighed heavily.

Su Yunchu didn't say anything, but Murong Yuan said, "after more than a month of war, do you have a further understanding of Yongning mountain?"

The Ministry of public affairs listened, looked up at Murong yuan, with a slight loss on his face, but someone said, "Lord, as we all know, Yongning mountain is easy to defend and difficult to attack, not to mention that we can't get close, but it's even more difficult to go up the mountain to explore the way and find a shortcut. After attacking for more than a month, I just think Yongning mountain is difficult to attack!"

This department is also the people who have been following Murong yuan. Although they fear Murong yuan in their hearts, they would never dare to talk to Murong yuan like this before. However, since Su Yunchu appeared, Murong yuan's mood will become very good. At least, the whole person doesn't look so cold. Although his highness King Jing still runs the army with the same preciseness and even more strict, However, it makes people slowly forget the cold, cold and alienated God of war two years ago.

The others will listen and say, "Yes, that's right, Lord. We spent more than a month and energy in Yongning mountain. In the early days, Gan Cheng didn't want to fight. He was also closed. We were allowed to attack. If we didn't fight, we wouldn't fight. This time, there was an additional second son of Lao Shizi in Yongning mountain. Beiliang was like a beast on the grassland. He had no rules."

The man said what everyone had in common. After listening, Murong yuan slightly raised his eyebrows at the beast on the grassland in his mouth, "Beiliang is a beast on the grassland! Did you know today?"

"This..." the original speaker didn't know how to answer.

However, someone continued, "now, in the face of Yongning mountain, the crossbow team personally trained by the princess has no advantage. Yongning mountain has complex terrain and ingenious gate construction. Neither crossbow nor bed crossbow can give full play to its greatest advantage, alas..."

Another helpless low sigh.

Indeed, since they came to Yongning mountain, the effectiveness of the crossbow and arrow team is not as good as a fish in water as attacking a city in an empty place.

Although the crossbow and arrow team has trained many field skills, because the terrain of Yongning mountain is complex and the defense is too good, now, although some people in the blue eagle secretly enter the mountain to find a shortcut, no one returns.
