(unchanged)

The shortage of sulphur did not affect the war tactically at least, and whether it affected strategically or not is another matter. Judging from the current situation, so far, the shortage of sulfur has not affected the strategic planning of the Chu army. The strategic intentions of seizing Bashu and Hanzhong were all successfully realized. The Dasanguan at the top of Chencang Road is still in the hands of the Qin army, mainly because the Han water above Tianchi Daze in winter is shallow, and it must wait until next year to march again.

The use of gunpowder and artillery was also used to attack the city, and the Battle of Weinan was the first large-scale battle in which artillery participated, but unfortunately because it was separated by Weishui at that time, artillery had little effect. Before the Battle of Linzi could be fired, Wang Jian retreated in great strides. Now go north to meet Li Xin, hoping that Li Xin will not run, and maybe he can try the power of artillery field battles.

At home and abroad, everything was finished, Xiong Jing waved off the five people, and after greeting him, he also went to the south of the city. Not only was the construction of the small town in the south of the city completed, but the vegetation covering the soil transplantation of the fortress was also firmly rooted. In the warm winter, the grass and shrubs are half withered and half yellow from a distance, and only some green is close to the ground.

The whole fortress looked very ungrandiose, it seemed small, and the prismatic corners that protruded outwards reinforced this impression, as if this was not a city fifteen miles square, but a city five or six miles in circumference. Only Xiong Jing knew that this fortress, which seemed to be five or six miles in circumference, actually cost more than 2,000 gold, which was enough to build a city of thirty miles square.

"Summoning the others here." The carriage did not drive into the shogunate next to it, but drove directly past the shogunate and stopped a few miles away from the small eup. Xiong Jing did not wait in the carriage, but got out of the carriage and walked on the dry grass in early winter.

Standing in this position, you can see that a dozen steps ahead is a trench that is not deep but extremely wide, and the trench is flat on the side of Xiongjing, but uneven on the opposite side. It was as if it were an enlargement of the small bastion jutting out above the surface, and within the trench there were triangular defensive bastions that began not at the surface of the earth, but at a distance of several miles.

But if you take a hundred steps back, or even only fifty steps back, you will not be able to see this trench about 30 meters wide. It's easy to mistakenly think that the grass stretches all the way to the bottom of the walls of the small fortress, and that if you climb the walls of the small fortress, you can easily occupy it. This illusion was deliberate, and the defense must not be fully displayed until the enemy was attacking the city, which was a small city five or six miles square, two feet and four feet high, with several prismatic corners sticking outward.

This is also where the money is spent. The small fortress on the surface didn't cost much, and the place where the money was spent was to dig trenches and pile up earthwork in the ground. The trench is also systematic, and it goes around the small town in a whole circle, and the inner side is the bastion under the surface. A circle of trenches is followed by a surface, and a second trench is one step ahead. On the surface, this is the small fortress that falls in the eyes of outsiders.

The entire bastion has three layers of defense, with the surface bastion being the last layer and two layers below the surface in front. The circumference of the 15-mile plot is 6,075 meters, and because it is a perfect circle, its diameter is 1,933 meters. The first two layers of defense occupy half of the diameter, and the remaining half of the diameter is a small fortress with a circumference of five or six miles.

The angles of several sides of the fort, the angles of the artillery firing in the fort, and the distance between the forts ...... all the results of accurate calculations. However, this kind of fortress is a product of the background of mercenaries, and the cost of war in this period is very expensive, and there is no salary and no pension, Xiong Jing is very worried that this kind of defense will be drowned by the corpses of the Qin army.

"I've seen the king, I've seen the king......" Qi Tong gasped, he ran over. He was followed by several other Mi men. These people are all Mi Xuan's younger brothers and nephews, although Xiong Jing is not much older than them, but in his eyes, these people are all little children.

"Excuse me." Several people were wearing leather armor, dressed like Chu army armor, and Xiong Jing didn't raise his hand to exempt them, and asked, "What is in the city?" ”

"Your lord......" A little kid spoke, and he was immediately pulled by someone. Next came Mi Tong's slow voice, "Tell the king, the villain is practicing, and I heard the king's call, so it's late." ”

The defense of the fortress mainly relies on artillery, and how these little children who have not entered the military academy fire cannons is taught by Xiong Jing, and then they teach it to the private guards of the Qi clan. The defense of the fort mainly relies on artillery, the first two sides of the prismatic fort are outward, and the last two sides are fired at themselves (the other prismatic fort), so as to form crossfire and eliminate the blind spots of firepower.

"How's it going?" Xiong Jing asked.

"Still unfamiliar." The beard on the upper lip of Mi seems to be thicker than Xiong Jing's, and the eyebrows and eyes are a little like Mi Xuan, but in fact, the eyebrows and eyes of both of them are like their fathers. "There is no medicine to be sent, and the soldiers are not enough......"

The first layer of the fortress defense has sixteen large triangular forts, the second layer is eight prismatic forts, and the third layer is six prismatic forts. The gun emplacements placed in the fort totaled one hundred and twenty. Although there were only sixty-four gun emplacements for the first tier, a total of 256 gunners were required for a four-man gun emplacement, and with the addition of armor, the first tier of defense required at least 1,000 men. There were not 1,000 people in the Qi clan, and even fewer people in Xiaoyi, men, women and children were together, barely getting together the gunners.

"The soldiers don't worry much." Xiong Jing Road. "The gunner is trained perfectly."

Soldier Xiong Jing can be transferred from the army, and four of the eight guards are enough, Xiong Jing is worried about the gunners. There is a shortage of gunpowder, and Xiaoyi is on the side of Yingdu, of course, the training cannot be live, otherwise those courtiers will scream again.

When Mi Tong wanted to say that there was no medicine to be done, Xiong Jing said, "Let's go." With that, he led the little boys to the trench ahead, which was facing a large triangular fort, the outermost part of the defense. Jumped into the ditch and turned around in the ditch for a small half circle before following the concrete road into the eup. At this time, Mi Xuan was already waiting.

The husband and wife just looked at each other at first, and when everyone avoided it, they hugged each other and kissed each other. Xiong Jing noticed that the woman's lips were a little cold. He smiled and said, "Li Xin's courage may not be greater than Wang Qian's, if he loses, the Qin State will die." ”

"Yes." Mi Xuan nodded heavily in belief, and she also smiled: "Doctor Yin Yan is in the middle of the fetal position, there is no need to use that ......"

Xiong Jing himself is a widow, and he was worried that his wife was also a widow, so he asked people to make forceps, but he didn't expect this thing to be needed.

"Great goodness." Xiong Jing smiled. He said, "If Li Xin escapes, I will rush back." ”

"Yes." The man said to hurry back, but Mi Xuan grabbed his white clothes very uneasily, afraid that he would find out and let go immediately, and then turned his back on his back and said, "Let's eat." ”
