Wei Zeng hoped that it was Qin at this time. As long as the Qin army could defeat the Chu army, the half city of Daliang could naturally be preserved. After saying this, he suddenly realized: If the Qin army really defeated the Chu army, then Wei would be in a tug-of-war between the two countries. Wei's national strength and soldiers would be consumed bit by bit, and a cold sweat suddenly popped out of his vest.

‘Boom, Boom, Boom, Boom,’While Wei Zeng was still fighting left and right in his mind, a loud bang came from the north of the city, and the entire beam seemed to be shaking, and the tremor made Yan Chao tremble even more.

"The King of Chu has attacked the city." Bai Yi sighed, knowing that it was the sound of a trencher smashing the wall.

"Wei State will be destroyed by the king!" Wei Jianyou said this and turned around and left.

‘Bang--, bang--, bang--,’ The sound of smashing the walls in the city and outside the city is different. The city is a relatively vague ‘Bang’, while the outside of the city is a clear ‘Bang’. Every time a thousand Chujin-pound wall-breaking bombs hit the city wall, a gravure mark will be punched on the rammed earth wall, mud and smoke will fly, and the Wei soldiers on the city are in a big uproar, and no one dares to stand on the bombarded city wall.

However, Daliang is the capital of Wei after all, no matter how thin the city wall of Jucheng or the Great Wall of Qi made of rocks. The bottom end of Daliang city wall is more than ten meters thick, and there are four meters at the narrowest part of the city. Such a thick city wall is not so much a smash, but rather a bit of it. After the rammed earth wall is smashed too much, it will peel off layer by layer.

This is related to the nature of the rammed earth wall. Such a wide city wall cannot be built as a plane. It can only be built side by side, so that it can be more than ten meters wide. Like reinforced concrete, in order to ensure that the construction and construction on a horizontal plane are closely connected, a lot of wood is placed horizontally in the rammed earth, and the ramming on the same horizontal plane is tightened by the friction between mud and wood. However, under the hammering shock of the 250 kilograms of city-breaking bomb, the mud and wood will become looser and looser, causing each building to fall off.

Of course, this process is not something that can be seen in one day or two days. It takes more than ten days or dozens of days to achieve this effect. Before this, several catapults had already targeted the city gate, which is the weakest link in the city defense system. However, before entering the city gate, the suspension bridge must be lowered or a pontoon bridge like the Qin army must be built.

After half a year of battle between Chen Ying, Xiong Jing knew how to defend the city. Now he was in a place where the Qin and Wei armies were standing at the former position, and he was a little confused. Fortunately, there were two generals in Chu State. Xiang Yan led more than 70,000 people to station Ao Cang, and Lian Po led a 150,000 army to station at Daliang City. As for the general Pang Nuan, who was expelled from Zhao State after Zhao Yan's death, he could only watch from the side.

Pang Nuan's hair and hair were all white, and compared with Lian Po who loved to doze off, he was much better in spirit. He also had another identity as Linwujun of Chu. His fief was in southern Hunan in later generations, and the southernmost edge of the administrative jurisdiction of Chu. He was both famous and vassal king of Chu. Not to mention taking Xiang Yan and replacing it, he could at least replace the too old Lian Po. However, the generals of the county had no good impression of him, so he could only stay with Xiong Jing.

"With this magical artifact, the city is like Tang Woxue." Pang Nuan looked at the catapult that kept firing stone bullets and hammering the city walls, and was so emotional.

"The general said that the Empress Dowager Zhao and the Marquis of Chunping?" Xiong Jing was also watching the catapult smash the wall, and he was still thinking about Zhao.

"Report to the king, that's it." Pang Nuan said. "Before the death of the Zhao king, the queen, had an affair with the Hou Chunping. When the death of the Hou, the Daoxiang king summoned the queen several times but failed to come. On that day, the queen regarded the Hou Chunping as the prime minister and abandoned Sikong Ma."

"In this way, is it the queen who affairs with the Marquis of Chunping?" Xiong Jing said. "Although Chunping was once the eldest son, this throne..."

"The king doesn't know anything." Pang Nuan is still familiar with Zhao State. "The queen was originally a daughter, and because King Daoxiang saw his beauty, he was appointed as the queen. His son was born, and the people of Zhao all thought of his eldest son Zhao Jia. If the Marquis of Chunping helped Zhao Jia ascend the throne and become king, the king of Zhao will be deposed now."

"Oh." Xiong Jing said, and then he remembered that there was another deposed prince Zhao Jia. In addition, he remembered Zhao Chen Guo Kai. Li Mu seemed to be killed by Guo Kai. "How about Guo Kai?"

"Guo Kai?" Pang Nuan didn't expect Xiong Jing to know Guo Kai. He replied: "Guo Kai is a favorite minister of Zhao Daoxiang. Although he is not a gentleman, he pursues the strategy of being close to Qin and breathes aside for Zhao."

"Where is Li Mu?" Xiong Jing asked another Zhao man again, "How about Li Mu? One day, will Li Mu be killed by King Zhao?"

Shortly after Li Mu defeated the Huns, Pang Nuan was the prime minister of Zhao when he left Zhao State. Now Li Mu was in command of the battle against Yan. A few days ago, he heard that Li Mu had captured Juyang, and was only one Juyongsai from Yan State. Xiong Jing said at this time that Li Mu was killed by King Zhao. Pang Nuan thought about it and then thought, and finally said: "I think if King Zhao killed Li Mu, he would be deposed because of the deposed Prince Jia."

"Yeah." Xiong Jing felt something. At this time, he was walking towards the dock under Chang Jiang's guidance. "You continue talking."

"I think Li Mu is a good general, not a good minister, nor a slander." Pang Nuan said this with Xiong Jing.

"In other words, Li Mu is the minister of the country." Xiong Jing once again mentioned this concept.

"However, Li Mu was a garrison in Daidi, and Daidi was located in the border area, and the people's customs were very different from Handan. Those who were unsatisfied in Handan often went to Jinyang before Jinyang lost. After Jinyang lost, they often went to Daidi, and even worse, they fled to the Huns. Now that the King of Zhao was established, Zhao Jia could not leave Handan, but many of his subordinates fled to Daidi. If Li Mu intended to help establish Zhao Jia, the King of Zhao should be punished."

"So that's it." Xiong Jing had some clarity. Perhaps Li Mu was killed by King Zhao because he was involved in the dispute over destruction and establishment.

Li Mu died and Zhao State was destroyed. Although the Qin army now regarded Chu State as its main enemy, Li Mu's importance to Zhao State is beyond doubt, and is even more important than Xiang Yan's to Chu State. After Xiang Yan, there were a large number of growing Chu generals. The difference between them and Xiang Yan was only in the ability to organize large-scale battles, but this was gradually being replaced by the Grand Sima Mansion.

After boarding the wing warship, the warship sailed to Putianze, where a large-scale battle was also underway: concrete pouring.

"Remember! Be sure to tamp it, be sure to tamp it." Feng Renjiu stood beside a shelf made of bamboo, watching buckets of stirred concrete hanging from the big boat and being poured into the giant bulb form by the rigorous man. He kept reminding him. He heard his instructions, the steel chisel in the hand of the craftsman kept tamping the concrete poured into the form to prevent gaps from occurring during pouring.

A large cluster of pillars grows in the garden of the withered lotus and yellow grass. The pillars grow beams, and the beam supports the granary floor.

More than 60 million stones of grain and fodder, one stone is 0.02 cubic meters, which is equivalent to occupancy of 1.3 million cubic meters. Assuming that the height of the grain and fodder pile is 6.5 meters, it will occupy a floor of 200,000 square meters. One stone weighs 13.5 kilograms, which is equivalent to 870,000 tons. Previously, the Grand Sima Mansion wanted to build a granary with timber, but considering that the total weight of grain and fodder was more than 600,000 tons (pre-estimated), it was finally changed to pouring with concrete.

Another way is to pile grain and fodder on the dry grassland. This proposal was quickly rejected. There were mudflats between the grassland and the water. With Chen Ying's experience of supply, mudflats made it difficult to dock the boats and oars, and transporting them in and out was very troublesome. In addition, the food and fodder itself, there was rain and snow in the autumn and winter, and the water level in the water in the water rose again in spring and summer. Before spring came, it was impossible to transport all the food and fodder away. As a result, most of the food and fodder would be soaked in the water, and less than half of the food and fodder could be transported back to the State of Chu.

Therefore, the first plan of the Grand Sima Mansion was to build a stanch concrete building with a length of one thousand meters and a width of two hundred meters (200,000 square meters). The project volume seemed huge, but this building did not require one day to be completed. The construction could be poured according to the speed of grain transport and expanded little by little. Suppose that 1.8 million stones of grain and fodder were transported every day, that is, 36,000 cubic meters, and based on the pile height of 6.5 meters, it covers an area of ​​5,538 square meters, just a floor of 75 meters by 75 meters.

According to the data from the Concrete Mansion, it takes 130 kilograms of concrete to pour a floor of one square meter. The concrete required is 720 tons (this number does not include beams and columns, and the concrete consumed by beams and columns is less than one percent). The concrete contains sand, gravel, water, and cement. It is less than 20% of the cement by weight. Even if it is 20%, the cement consumes only more than 140 tons per day.

The consumption of giant tendons is less than cement. Pouring one square meter requires 130 kilograms of concrete, which consumes only 10 kilograms of giant tendons, and 5,538 square meters is only 55 tons. Sand, gravel, and the Yellow River, and all the water banks can be dug, which is not troublesome.

The real difficulty lies in transportation tonnage and cement consumption.

The daily transportation of 1.8 million stones is 2.43 million tons, which is the amount of transportation twice a day and night. The actual transportation tonnage is only more than 12,000 tons. Concrete pouring requires 2,000 tons tonnage. If these 2,000 tons are subtracted, the grain transport tonnage is only 10,000 tons.

Cement and giant tendons have to be transported from Yingdu, a thousand miles away. Although the two are only 200 tons, they can travel day and night, and it takes ten days to travel back and forth between two thousand miles. That is to say, another 2,000 tons of transportation tonnage will be wasted between Putianze and Yingdu. The tonnage of the actual grain transport is only 8,000 tons, and the transportation of day and night is more than 16,000 tons, totaling one and two million stones.

The transportation tonnage may be solved by borrowing the boats of Qi and Zhao countries. If the cement is insufficient, Qi and Zhao countries will not be able to help. A 1,000-meter-long, 200-meter-wide dry-style building with an area of ​​200,000 square meters requires 26,000 tons of concrete. The width of these concrete requires 5,200 tons of cement. Where can the Chu State have 5,200 tons of cement?

After confirming the construction of the concrete granary, the Zaofu immediately expanded the cement plant on a large scale. The planned daily output is 50 tons, and the daily output can be 4,500 tons of cement in three months. In addition to the 700 tons of cement in hand, it can reach 5,200 tons. But now, the cement plant has only expanded five, with a daily output of only 20 tons.
