Chapter 995

Although Chu Yunxuan won the war again, he also paid a great price. The reason why they dare to light a fire on the wall is that Xin Yi once told Chu Yunxuan the principle that fire oil can catch fire and sand can put out the fire. He first asked people to put a layer of sand on the wall, and then attached a layer of plant leaves on it, Then he simulated the appearance of a layer of wall bricks on it to make the texture of the wall. Finally, he coated it with a thin layer of fire oil. When they lit the fire, it would quickly spread throughout the wall. But when they wanted to put out the fire, Chu Yunxuan also asked someone to prepare a lot of sand and water to cover a huge cloth, From above the city wall, they covered the whole area, so that they could eliminate the fire. However, this method could only be used once, and the cost was very high. When Chu Yunxuan did it, in order to really hide people's eyes and ears, he sent people to do it quietly at night and in batches, So the spies of the Eastern Wei state and Xuanyuan state didn't find out about it, but they really wasted a lot of effort, manpower and financial resources of Chu Yunxuan, and finally achieved this effect. Fortunately, it also played its due role, but Chu Yunxuan is very worried now. This attack shows that Xiao Jinrong's mind has reached a very precise state, For the imperial city of northern Yan, it's also a must. If it continues like this, Chu Yunxuan's preparations won't last long. This time, Xuanyuan's army suffered a lot. They need a period of time to rectify. In this case, Meng Yuan and Xuanyuan can't agree to send troops with the Eastern Wei, and the Eastern Wei can't send troops without authorization, Therefore, Chu Yunxuan won a period of preparation time for everyone. But when the Eastern Wei and Xuanyuan armies set out again, the forces of Beiyan imperial city were hard to resist. At that time, they had to fight to defend the city. But the military supplies in Beiyan imperial city were consumed every day. Now, although the Eastern Wei and Xuanyuan failed to attack the city, they surrounded it, It's impossible for them to transfer materials from other places, and it's also impossible for a large number of reinforcements to advance to Beiyan imperial city secretly from other places. In short, with the manpower, material and financial resources in Beiyan Imperial City, it won't last long. Next, it may be a bitter battle. Chu Yunxuan looks at the postwar Beiyan Imperial City, although the fire was put out in time, However, it still spread to the northern Yan imperial city. Looking at the blackened wall, Chu Yunxuan felt very heavy. The northern Yan imperial city was defended by their lives for generations. Chu Yunxuan didn't want the northern Yan kingdom to be captured by others in his generation's hands, and he didn't want the people of the northern Yan kingdom to be baptized by the war, Chu Yunxuan looks up at the sun that has set in the West. He has infinite emotion in his heart. He hopes that it will be dawn soon after sunset. There will always be some hope in life. He will not give up until the last moment. He will stick here. As long as there is a trace of hope, he will stick to it. This is Chu Yunxuan's persistence!
