The shortage of sulfur did not affect the war tactically at least. As for whether it was strategically affected, that was another matter. Judging from the current situation, the shortage of sulfur did not affect the strategic planning of the Chu army so far. The strategic intentions of seizing Bashu and Hanzhong were all successfully realized. The Dasan Pass at the top of Chen Cangdao were still in the hands of the Qin army, mainly because the Han River above the Tianchi Daze in winter was shallow, and it must wait until next year to advance again.

Gunpowder and artillery are still used to attack cities. The Battle of Weinan is the first large-scale battle in which artillery participated. Unfortunately, the artillery was not very effective at the time when it was separated by the Wei River. Before the Linzi Battle could fire, Wang Jian stepped back. Now he is heading north to face Li Xin, hoping that Li Xin will not run away, and maybe he can try the power of artillery field battle.

At home and abroad, everything was said, and Xiong Jing had just retreated for five people. After Beichen Palace asked him about his wish, he quickly left the city and went to the south of the city. Not only was the small city completed, the grass transplanted on the fortress soil also firmly took root. In the warm winter, the grass looks half dry and half yellow from a distance, and only the places close to the ground are a little green.

The entire basin looks very unmagnificent and small. The six prism-shaped top corners extending out deepen this impression, as if this is not a city of fifteen miles, but just a small town of five or six miles. Only Xiong Jing knew that the building of this basin, which looks like a 5 or six miles, actually cost more than two thousand gold, which is enough to build a city of thirty miles.

"Zhao Mi Tong and others come here." The carriage did not drive into the shogunate next to it, but drove directly through the shogunate and stopped a few miles away from the small town. Xiong Jing did not wait in the carriage, but got out of the carriage and walked on the dead grass in early winter.

Standing at this position, you can see a trench that is not deep but extremely wide apart from the front. The trench is flat on Xiongjing, but not flat on the opposite side. This seems to highlight the expansion of the small ridge above the surface, and there are also triangular defensive fortresses extending outwards in the trench. The defense of the ridge does not start from the small ridge on the surface, but starts several miles away from the small ridge.

But if you step back a hundred steps, or even only go back fifty steps, you won't see this trench about 30 meters wide. This can easily make people mistakenly think that the flat ground with dead grass extends to the wall of the small castle, and think that as long as you climb the wall of the small castle, you can easily occupy it. This illusion is intentional, and defense must be fully displayed when the enemy sieges the city. Before the siege, this is a small town with five or six miles square garden, two or four feet high, and several prism-shaped top corners extending outward.

This is also a place to spend money. The small trench on the surface does not cost much. The place to spend money mainly requires digging trenches on the ground and pile up earth. The trench is also systematic, and it is a whole circle around the small trench. The side to the inner side is the trench below the surface. After a circle of trenches outside, it is the surface. A section of the trench is forward to the second trench, and then it is the trench that falls into the eyes of outsiders.

The entire basin has three layers of defense. The basin on the surface is the last layer, and there are two layers below the surface in front. The circumference of the plot of fifteen miles is 6,075 meters. Because it is a perfect circle, its diameter is 1,933 meters. The defense in the front two layers occupy half of the diameter, and the remaining half is a small basin with a circumference of five or six miles.

The angle of several sides of the prism, the angle of artillery shooting in the fort, the distance between the fortress... These are all the results of accurate calculations. But this fortress was a product of the background of mercenaries. At that time, the war cost was very expensive. In the era when there was no salary and no pension, Xiong Jing was very worried that this kind of defense would be flooded by the corpses of the Qin army.

"I have seen the king, I have seen the king..." Mi Tong gasped, he ran over. There were several other Mi men following him. These people were Mi Xuan's brothers and nephews. Although Xiong Jing was not much older than them, in his eyes, these people were little kids.

"No gift." Several people were wearing leather armor and dressed as a Chu army soldier. Xiong Jingshou did not lift them up and asked, "What is the matter in the city?"

"Report to the king..." A little kid bowed and wanted to speak, but he was immediately pulled by someone. Next was Mi Tong's slightly mature voice, "Report to the king, the villain is practicing, and he heard that the king was summoning, so he was late."

The defense of the lever is mainly based on artillery. How can these little kids who have not entered the military school be fired by Xiong Jing, and then they teach the private soldiers of Mi. The defense of the lever is mainly based on artillery. The first two sides of the leverart are fired outward, and the latter two sides of the leverartartery fired at themselves (the other leverartartartery) to form cross-fire and eliminate the dead end of fire.

"What's wrong?" Xiong Jing asked.

"It's still not familiar." Mi Tong's beard with her upper lip seemed to be thicker than Xiong Jing's, and her eyebrows looked a little like Mi Xuan. In fact, both of them looked like their fathers. "There is no medicine to be released, and the soldiers are not enough..."

There are sixteen large triangular castles on the first floor of the bastion, eight prismatic castles on the second floor, and six prismatic castles on the third floor. There are as many as 120 gun positions arranged in the castle. Although there are only 64 gun positions on the first floor of the defense, four people and one gun position requires a total of 256 gunners. In addition to armored soldiers, the first floor of defense requires at least a thousand people. There are no thousand people in the Mi family, and even fewer people in Xiaoyi. Men, women, young and old are in battle, and only then can we gather more than 200 gunners.

"Soldiers don't need to worry too much." Xiong Jing said. "You can be proficient in gunner training."

The armored soldiers Xiong Jing can be dispatched from the army, and four of the eight guards left were enough. Xiong Jing was worried about the gunners. Gunpowder was short of gunpowder, and Xiaoyi was on the side of Yingdu. Of course, training could not be done in real-time, otherwise the courtiers would scream again.

When Mi Tong wanted to say that there was no medicine to be released, Xiong Jing said, "Let's go." After that, he took these little kids to the trench ahead, which was facing a large triangle fort, which was the outermost area of ​​defense. He jumped into the trench and turned half a circle in the trench before entering the trench along the concrete road entering the trench. At this time, Mi Xuan was already waiting.

At first, the couple just looked at each other, and waited for everyone to avoid it before hugging each other and kissing each other. Xiong Jing found that the woman's lips were a little cold. He smiled and said, "Li Xin may not be more courageous than Wang Jian. If he loses, Qin will be destroyed."

"Yeah." Mi Xuan pointed to her confidence, and she smiled and said, "The doctor Yin Yan's fetal position is very high, so it is not necessary to use that..."

Xiong Jing was a child, worried that his wife would be a child, and he asked someone to make a child with forceps, but he didn't expect that that thing was not needed.

"Great kindness." Xiong Jing smiled and said, "If Li Xin escapes, I will hurry back."
