Chapter 667

Su Yunchu only calmly put away the jade pendant in his hand, "The old general knew this thing, and song an would not say more. In fact, he had bypassed Xuanmen pass two days ago. Now, half of the food and grass in Beiliang was burned. Beiliang must think that the Lord's reinforcements are close at hand and will not send troops rashly. Therefore, there should be no more fierce fighting in front of Xuanmen pass these two days, and the soldiers can have a rest."

But looking at Su Yunchu's jade pendant, Shou yuan stood up and held Su Yunchu's shoulders. "Didn't the blue eagle come with Prince song?"

He couldn't hide his excitement. Muhan Heying Li on one side had frowned at this posture. If Murong yuan was present, just Shouyuan's gaffe and excited behavior, Murong yuan probably wouldn't worry about whether the general was a veteran.

But Shouyuan also let Su Yunchu go in the instant of Shouzhong's stop and Su Yunchu's surprised look. Su Yunchu said quietly to the previous one, "old general, blue eagle didn't come with us. Only the next three people came to the Xuanmen pass this time."

Shouyuan's face regained his serious look, "before the blue eagle arrived, King Jing's future, but the soldiers in the pass have been seriously injured. This... Within two days, Beiliang reacted. Can Xuanmen pass wait for the king?"

Su Yun saw this for the first time. He looked at Shou yuan firmly. "Old general, you can't wait, you have to wait. You and I all know that the Xuanmen pass can't be lost, you can only defend it!"

Su Yunchu's eyes were too firm, and he said firmly that Shouyuan looked at them, and the elimination of the moment just rising disappeared. Instead, he became more firm.

However, after settling down, several people sat together. Shou Zhong only looked at Su Yunchu and said, "the grain and grass in Beiliang were really burned by the three?"

It's no wonder Shouzhong's skeptical tone. In his opinion, Su Yunchu's three people, young people who don't seem to have much experience, are almost one ring younger than him. It's OK to burn the grain and grass in Beiliang. How can they do it.

Su Yunchu didn't see any negative emotions about Shouzhong's skeptical tone. He just nodded and said, "fortunately, he has lived up to his mission."

At this moment, even Shouyuan was curious, "I don't know how master song did it?"

Su Yunchu only said, "the three of us sneaked into Beiliang military camp and deployed quietly. We didn't find the opportunity to detonate Beiliang grain and grass until after noon today."

"Detonate?" they've never heard of anything but burning grain and grass. Why ever detonate.

Su Yunchu simply talked with Shouyuan and Shouzhong about the principle of dust explosion. In recent days, the climate around Xuanmen pass is dry, while the grain and grass in Beiliang has a lot of dust in the area where the grain and grass are located due to the eating habits of Beiliang people, and the dust density is high. In addition, due to the dry weather, it is easy to cause dust combustion and explosion. Su Yunchu also uses this point, With the help of three people, it causes dust combustion and explosion. The most remarkable feature of dust explosion is that it will cause continuous explosion. Therefore, half of the grain and grass in Beiliang can be burned in their relatively easy action.

After listening to Su Yunchu's explanation, although Shou yuan and Shou Zhong still know and understand, they also know the knowledge conveyed by Su Yunchu that they have never known.

At the moment, I had to sigh in my heart. No wonder King Jing could give the blue eagle's token to Su Yunchu. No wonder Su Yunchu came to the Xuanmen pass. No wonder she easily let Beiliang retreat. This man, he used infinite wisdom to break the enemy.

Shouyuan sighed, "Prince song has unparalleled intelligence."
