When the struggle between the various forces in the northwest was in full swing, in Hebei, a general on a white horse had just crossed the Yellow River and was about to go to the Central Plains.

He is Zhao Yun, with the help of Pan Yu, he was able to free himself from the prison in Yecheng, at this time Yuan Shao has not returned to Yecheng, and is still attacking Gongsun Zhan's last territory - Yijing Tower.

Out of the idea of wanting to defeat Gongsun Chan by an overwhelming margin, Yuan Shao summoned Pan Yu and Gao Ran and others back to the front line from Yecheng as soon as they recovered from their injuries, and some other generals who had not participated in the decisive battle with Gongsun Chan before were also summoned.

Pan Yu saw that the lord Yuan Shao had been anxious recently, and knew in his heart that this was not the best time to tell him that Zhao Yun had left, so he didn't mention it directly, but fortunately, Yuan Shao didn't care too much about Zhao Yun and didn't ask.

Yi Jinglou was extremely difficult to conquer, Gongsun Zhan gathered all the generals under his command, and went to the territory to find all kinds of skilled craftsmen, mined a large amount of wood and stone, and built it into a fortification close to perfect defense.

The foundation of the building is built with a large number of stones, tamping and indestructible, any bow and arrow throwing stones can not be destroyed, the high foundation of the building is ten meters high from the ground to the top, ten meters above, the use of a large amount of wood to build a beautiful pavilion, in the hollow wood carving outer layer, but also reinforced a layer of smelted metal plate-like defense, which can be regarded as quite exquisite technology at that time.

In short, on the whole, it doesn't look like a place of refuge for the needy, but more like a luxurious palace.

The building is stacked with the wealth and family members that Gongsun Chan has accumulated over the years in his territory, and the soldiers are at various lookout points, which can not only probe the military situation in the extreme distance, but also shoot crossbows and crossbows to shoot the enemy.

"Charge me, it's just a broken building. Don't be discouraged! ”

Yan Liang stood in the middle of the army, facing a large amount of arrow rain radiating from Yi Jinglou, and he commanded the soldiers to launch attacks again and again. However, there was no use at all, and the ladder could not be taken to the top of Yi Jing's tower at all, as for the catapult. There is no way, no matter how big the stone is thrown on the dense iron plate outside Yijing Tower, at most it will only make a loud noise, making the whole iron plate shake slightly.

The soldiers of the Yuan army could only use the shield as a barrier and slowly march towards Yi Jinglou, and then the archers under the shield shot a few flying arrows upwards with difficulty.

Yuan Shao has been dying of sorrow for the past few days, he thought that he could drag the food supplies and military equipment to Gongsun Zhan's Yijing Building, but in recent days, he found that Gongsun Zhan's various kinds have not been cut off. And there are more and more feather arrows, many of which are newly made, and there is no sign of recycling at all.

Yuan Shao's advisor Fu Zhi came out of the banquet and said: "My lord, as far as the minister can see, Yi Jinglou is far from being as simple as we imagined, and under his stone foundation, there must be a place for casting and planting grain. ”

Guo Tu smiled: "It's really a joke, if there is no sunshine in food." How does it grow, and where does the drinking water come from? ”

Frustrated and angry: "You concubine." Don't you hear the word of mouth of the soldiers on the front line, and some soldiers near the bottom of the Yijing Tower have sent back a message, saying that the stone foundation seems to be complete, but in fact, the surface is covered with all kinds of small holes that are difficult to detect with the naked eye, so small that it seems to be pierced by a slender silver needle. The sunlight from the outside world must be able to shoot into it, but the feather arrow cannot enter; As for drinking water, don't you know that there is a well when you dig three feet into the ground? When Gongsun Chan built Yijing Tower, he must have chosen a place where he could drill wells. This building is so elegant, how can you, a man who flatters in the presence of the lord all day long, understand? ”

Yuan Shao frowned, and he didn't have time to care about the two strategists, but said anxiously: "In this way, this Gongsun Chan actually built such a perfect pavilion?" ”

Tian Feng said slowly on the side: "Lord, why worry, with all kinds of manpower and material resources within my power, why is it difficult to build such a building?" Even if it's ten, it's no problem. It's just that we need to take into account the long-term development of our forces, and it is not appropriate to use all kinds of forces on such extravagant and clinging to things; Gongsun Zhan is different, he is trapped in a corner and devotes all his national strength to build such a Yijing Tower, which is also wise, and the lord does not need to be envious. ”

"Well, Tian Feng is right." Yuan Shao nodded, his face was full of gloom again, "But can I wait here to stalemate with Gongsun Zhan?" ”

Pan Yu sat under the tent, looked around at the strategists, and thought in his heart: although his act of releasing Zhao Yun was correct in his opinion, if he told Yuan Shao that with Yuan Shao's character, he would probably be reprimanded, but if he made a contribution at this time and told Yuan Shao about it when he was happy afterwards, Yuan Shao would not be too angry.

Thinking of this, Pan Yu stood up and said to Yuan Shao politely: "Lord, the minister thinks that Yijinglou is easy to defend and difficult to attack, if it is attacked, I am afraid that it will be inappropriate, but if it is a stalemate, it will lose a lot of fighters in the Central Plains. In this way, the soldiers can be bloodless, and such a magnificent building as Yijing Tower can also be preserved. The minister is not talented, and he is willing to take on this responsibility. ”

"Gongsun Chan and I have a deep grudge, and we have fought many battles big and small, how can I be willing to obey?"

"Please send me to give it a try." Pan Yu said frankly with a face.

Yuan Shao really had no other way but to grant Pan Yu's request and let him go to Gongsun Zhan's Yijing Building the next day as a messenger.

At the same time, when he landed on the land of the Central Plains at Guandu Port, Zhao Yun rode on a white horse and looked at the sky, the sun was very dazzling, and he was a little confused and didn't know where to go. As a prisoner who was rescued by others, Zhao Yun was very grateful to Pan Yu in his heart, and he wanted to go to Luoyang City that Pan Yu said, but unfortunately, he inquired along the way, but heard that Zhao Yue of Luoyang had already led his troops to Hongnong.

In desperation, Zhao Yun could only go to Xuzhou first to find the Mingjun in his heart he wanted to visit before-Liu Bei.

At the same time, in Jiangdong, Sun Ce had already launched an attack on Jianye City, and Liu Yao, as the only Liu clan relative in Jiangdong, gathered several other princes to encircle and suppress Sun Ce together.

In Shentingling, Sun Ce's generals showed extraordinary ability, and Zhang Zhao and Zhang Hong issued an article on the people's list, which concisely and clearly conveyed the information on how to govern Jiangdong to the local people, and instantly won the hearts of the people.

Zhou Tai and Jiang Qin were in charge of the unified army, and Zhou Yu and Sun Ce were in command, and a fire burned down the granary camp of the Jiangdong coalition army guarded by Yan Baihu, so that Liu Yao's soldiers lost their basic ability to eat and wear. (To be continued.) )
