As time entered May, as the POWs' thoughts were unified, Ji Han's trench excavation progress suddenly accelerated. On May 15, many branch trenches connected from the outer ring (500 meters away from the city wall) to the inner ring (300 meters away from the city wall) had been excavated. Li Xiang, who was very satisfied with the progress of the project, directly added meat to the food of the prisoners of war. He also made it clear that as long as the quality of the project continues to ensure that the meat added to each meal will not be cancelled and will continue until the end of the war.

Then, the prisoners of war, whose morale was rising again, began to quickly dig out the planned inner ring.

Three hundred meters have entered the effective range of the catapult set up on the tall city tower in Luoyang. Therefore, starting from the inner ring excavation work, the Luoyang defenders, who had been in a wait-and-see state, began to use the catapult to attack the Han army captives who were digging the trench under the command of the prince in each section.

However, under the protection of a layer of earth wall, the effect of such an attack is very poor.

"Huh? Brother Wang, why are you here? I haven't been attacked here."

"Hmph, if Brother Wei doesn't come, I don't know how you will make a fortune!"

"Uh, Brother Wang, what do you mean by saying this? I don't understand very well."

On May 16, Simalun, who was guarding the south gate, learned that the enemy's engineering team had entered the range of his catapult, excitedly ordered him to be responsible for this section. Nearly a hundred catapults were fired together. In just one hour, thousands of stone bombs were fired. Moreover, as a noble family who received a good education since childhood, Simalun also asked the defenders to ignite the stone bombs before firing them out. So half of the sky was filled with long tail flames pulled out by the burning stone bombs, which seemed spectacular for a while.

After these stone bombs landed, they did cause some trouble to the prisoners of war team under construction: I just dug out the stacked soil, and your stone bomb was blown back into the pit. I was burying my head in the trench, but suddenly a large pile of soil shattered almost buried me alive...

That's the effect. There were only one stone bullet with a character burst out from the city wall. After being thrown out of the city wall, its parabola was extremely perfect. It just landed in the trench without being blocked by the earth wall above the trench.

However, there was no one in that section of the trench at that time!

Therefore, the casualties caused to the Han army by thousands of stone bullets were zero!

"Wen Ju, who is in charge of the city guarding supplies, came to report to Brother Wei, saying that it was King Zhao, you asked him for a thousand stone bullets around noon today?"

"This is indeed the case. Brother Wang, the Han army facing this line of defense has entered the range. I ordered people to throw a thousand stone bullets this morning. Then I naturally have to find Wen Ju to make up for it in the afternoon. Is there any problem?"

Before the victory or defeat of the Battle of Daluze, Sima Gui, the Taiyuan King who had been serving as the nominal commander on the Bingzhou front, was no longer a military novices. Hearing Sima Lun's words, he was of course angry: "No problem, the problem is big! I will ask you, how long does a thousand stone bullets need to be polished by craftsmen? How effective will this thousand stone bullets be fired?"

"Hey, why is Brother Wang also as meticulous as those ordinary people? How can we calculate these small things when we do things? When the enemy approaches, we have to launch thunder to destroy his courage!"

"Hey!" After hearing this, Sima Gui wanted to slap this guy. Finally, he remembered that this guy's father was Sima Yi, and his father was only Sima Fu, so he still held back: "Ziyi, do you know how long does a stone bullet need to be polished by a craftsman? Luoyang is now an isolated city, and the supplies in the city are less. Today, the stone bullet you shot in an hour will require ten craftsmen to polish it for a month. It is one percent of the total number of stone bullets in Luoyang City Defense Stock. We plan to hold on to at least half a year! We have to be very careful with your brother, of course we have to be very careful."

"Of course," Sima Gui's tone became more excited when he said this: "If you hit the stone bullet, you can achieve good results, and Brother Wei has nothing to say. But look at what the things you shot this morning have achieved? Have you delayed the enemy's progress? Have you ever panicked the other party? How many enemy troops may be killed?"

"Well...hum!" As Sima Yi's youngest son, Sima Lun received the most favor from his father and brother since childhood. At this time, he was scolded by Sima Gui for so long and was already very well-educated. After Sima Gui directly pointed out the fact that he was wasted supplies without any results. The guy jumped up suddenly: "The enemy is getting closer and closer to the city wall! If there was no stone bullet, he would stare at me. I am afraid that when the enemy digs the wall, you don't know what to do! Isn't this throwing a stone to ask for directions? Ah! Taiyuan King! What qualifications do you have to shout at me here? If you hadn't lost Taiyuan County, Guan Zifeng could come here to confront me? Hum?"

"You...you, you...good! What's the matter with our Shuda family? I don't care! I don't care! Come on, prepare a car, I want to enter the palace to meet Your Majesty and beg for bones!"

...

Let’s not talk about the mess inside the Sima family. On May 30th, a cheer came from the Luoyang city: several segmented trenches had been opened, which means that the inner ring 300 meters away from the Luoyang city wall had also been completed.

"Hehe, the mountain chief, the progress this month is pretty good, right?"

"Well, it's good. It's great to be able to maintain such speed even when attacked by enemy troops."

"Then the mountain chief, did the student pull the catapult into the trench?"

"But, try it at 300 meters first. If the effect is not good, then dig forward."

"Here!"

The Han army's prisoners have been digging trenches desperately in the past two months, and the Han army's craftsmen have not rested for this period.

In the past two months, many big trees on the mountainous areas near Luoyang, such as Yushan, Mangshan, Qingyaoshan, Jingzishan, etc., have fallen into great danger and are cut down by Han army craftsmen. They are then pulled into the rear army camp and cut into various parts.

With Guan Yi's permission, under the command of the Han army, the prisoners of war quickly moved the parts along the trench towards the city wall. After they got the inner ring trench, under the command of various craftsmen, they quickly began to assemble some specific and wide areas in the trench under the command of various craftsmen.

"Master, great king, big thing is not good, please come to the city to watch!"

A few days ago, the lawsuit against King Zhao of Taiyuan and King Zhao hit Sima Yan's imperial front. Sima Yan had no choice but to beat fifty boards each: this is definitely favoring Sima Lun.

But that's it, Sima Lun was not happy. The young master had no passion for just being appointed during this period and spent every day eating, drinking and having fun in a private house under the city wall.

After waiting for this day, he was called by his subordinates. After reluctantly climbing to the city, he watched the city under the guidance of his subordinates for a long time...

"You called me up, what do you want me to see?"

"King, the Han army is assembling a trench outside the city."

"Huh? What do the Han army want to do? The catapults that our army has built on the city tower are very difficult to project stone bombs to them. They set up catapults so far on the ground, but they can't hit us at all!"

"King, the Han army's catapult doesn't need to hit us, it's enough to hit the city wall."

"What's the use of hitting the city wall?"

"Oh, my king, although the walls of Luoyang City are extremely thick, they are just rammed earth walls. As long as the Han army's trenchers can hit our city walls, they can use hundreds of trenchers to aim at a certain section of the city wall for thousands of times and tens of thousands of fixed-point bombardment. No matter how strong the Luoyang city wall is, it will not last long."

"Ah? Then you won't fight back?"
