Behind the Otemon Gate of Waimaru is, the building inside Outer Maru.

There are horse farms, shooting ranges and other military training in the building, as well as Yashiki where Li Xiao lived close to the samurai, such as Shima Katsutoshi, Shioka Kazuha, Kohata Xiaoken and other people and their families stayed here.

In addition to these buildings, there is a road that runs directly from behind the Outer Maru Otemon Gate to the gate of the Jinmorimaru.

The trail is quite long, winding uphill, and there is no shelter on the trail, completely exposed to the firing range of the Honmaru, the Jinmorimaru warp.

In other words, if the enemy breaks through the Oteemon Gate of Outer Maru, they will have to think about attacking the gate of Jinmorimaru along the second platform on the roadway.

On the horse road, the enemy army will be shot at by the defenders of Honmaru and Jinshomaru, and only after paying the price of casualties can they finally attack the gate of Jinshomaru Castle.

Compared with the Oteemon Gate of Waimaru, in the design of the Castle Gate of the Shrine Shomaru, Li Xiao added elements of the Chinese Urn City to this point, making a double gate structure at the front and rear.

In fact, the design of this Weng City was not original at that time.

In the design of the city gate, the outer cypress-shaped tiger mouth and the horse have the shadow of the design of the urn city. However, these two designs are not mainly considered to be used for killing and injuring the enemy forces in the city, but mainly as a buffer belt for another city gate after the main city gate is breached.

Therefore, Li Xiao also adopted the method of Goryeo Gate in the design of Shenshou Pill. The lower level is the gate, and the upper level is the curved wheel plus the shooting port.

However, the gate of the Jinmori Maru was designed with reference to the Chinese Castle Castle, and the Goryeo Gate was made into a front and rear double curved wheel, and a narrow room was opened on the back of the curved wheel of the gate, which could be used for shooting, so as to prevent enemy troops from climbing from the north in terms of safety protection.

However, due to the time constraints, this urn city can only be delayed until the next year.

Because of the time constraints, Li Xiao gave up more than that, Li Xiao originally wanted to build a stone wall on the outer wall of the table where the Shenshou Pill and the main pill were located.

Ishigaki is built with stones one by one, and it is mainly used to prevent the enemy from climbing directly from the horse path of the outer maru, and the difficulty of the main maru is also used to prevent the enemy from digging.

The earliest large-scale use of Ishigaki was when Kublai Khan attacked Tsurumon, when the former Hojo family, who held the power of the Saymoto at that time, learned the lesson of the first Yuan army landing, and ordered people to build a long stone wall similar to a stone embankment along the coast of Hakata Bay in Kitakyushu to prevent the Yuan army's ships from landing by sea.

In Kublai Khan's second attack on Yuben, during the Battle of Hong'an, after the warships of the Yuan army arrived in Kyushu, as far as the eye could see, the coast was full of stone walls built of huge stones, and there was no place to land.

In the end, it was hit by a typhoon again, and more than 100,000 troops were hung up.

However, although Kamiokan Castle did not use a stone wall, because it was built on the side of the mountain, after digging out the grass and mud on the surface, the inside was hard mountain stones, so it temporarily replaced the role of the stone wall.

At the same time, in order to strengthen the defense, Li Xiao also prepared to build five turrets in Shengang City, two outer pills, two divine shou pills, and one main pill. And according to the height of the position of the oar, they are named one oar to five oars.

The design of the oars is a bit like the Chinese arrow tower, but the function is not limited to one kind of arrow turret.

For example, Li Xiaojian's turret in the castle tower is called the taiko drum turret, which is generally used when there are special circumstances, when the taiko drummer beats the drum on it to convene all the retainers to discuss the matter, or to convene the standing reserve to defend against the enemy.

All the turrets of Kamiokanda Castle are unified in two layers, which are called double turrets, and the upper layer is used for early warning, fire bows and arrows or iron cannon shooting, while the lower layer is used for materials and equipment.

There is not much difference between the turret and the castle tower, and in general, the castle tower is actually the largest turret in the city.

The castle tower is usually located in the main maru, and it is the core part of a castle and the last line of defense. Standing on the top of the castle tower, the lord of the castle can get a bird's-eye view of any corner of the castle, and it is easy to feel superior to ten thousand people on it.

In addition to its military use, the castle tower also served as a place for the lord and his family to live, and it was also a place where important matters were discussed and judged between the lord and his retainers.

Speaking of the castle tower, I have to mention that Azuchi Castle and Osaka Castle in the Azuchi-Momoyama period, Oda Nobunaga and Toyotomi Hideyoshi were both from the world at that time, and the Azuchi Castle Castle was a seven-fold castle tower, and Osaka Castle went further to the eightfold level.

Oda Nobunaga also pasted gold leaf on the exterior of the castle tower of Azuchi Castle, and Toyotomi Hideyoshi paved the third floor of the Osaka Castle castle tower with gold for a tea room. However, with such a luxurious style, you can also see the mentality of the two of them showing off their wealth.

In contrast, the later Tokugawa Ieyasu did much better in this regard.

Li Xiao made the castle tower into a triple castle tower, although it is not high, but it occupies a very spacious area.

The assessment room is large enough to accommodate nearly 50 people and retainers to discuss together, and at the same time, Li Xiao dug many small pools around the castle tower, which is said to be used as an ornamental scenery, in case the water source is cut off, it can also be used to draw water.

After the general design of the entire Shengang Castle was completed, Li Xiao let the island Katsumeng, Shioka Kazuha, and Kohata Xiaoxian was responsible for the military garrison tasks.

The construction and disposal of the entire castle was entrusted to Ōzo Yasushi and Kinoshita Koichiro.

Ōzo Chang'an is responsible for overall planning and distribution, while Kinoshita Koichiro is in charge of supervision and management.

A month after the construction of the castle began, everything went smoothly, and with the exception of the outer horse fence, Horikiri was completed within a few days of the start of the battle. The earth was then compacted, and the piling process progressed quickly, and by mid-August, the construction of the outer pill was completed.

During this period, the sister's family secretly sent ninjas to the wood accumulation site in Li Xiaocheng, trying to set it on fire, but it was detected by Yokotani's ninja premise, which bankrupted the sister's family's conspiracy.

In September, the two arrowheads of Outer Pill had been built, and the defense of Outer Pill was initially completed.

After that, Sister Xiaolu's family couldn't sit still, and dispatched 300 troops to attack at night.

Li Xiao's two hundred standing turtles retreated in Kamioka Castle, and with the help of the anti-horse fence and Horikiri, they repelled the sister road army with iron cannon bows and arrows.

However, where Kamiokanda Castle was hoarding wood, it was attacked by the sister army with rockets throwing torches and arrows tied to cotton cloth.

Li Xiao's hoarded wood was partially burned.

Immediately, Li Xiao spent two more days of effort, and once again introduced the wood for the construction of the city from the plateau river into the castle town.

Affected by this delay, the speed of the construction of the city slowed down, as the construction period got closer and closer, Li Xiao had to speed up the construction of the city, and the next day was heavy rain, scorching sun, and did not stop the action of building the city.

After the end of the autumn harvest.

Li Xiao ushered in a particularly meaningful news for life, Yumi Kohata is pregnant, and it is expected that she will give birth around the New Year next year.

Li Xiao was blinded by this news for no reason, I am actually going to be a father.

On the other hand, the retainers of Shima Shengmeng are even more excited, Li Xiao's heirs, for them, Li Xiao's family has been inherited, and the object of allegiance can be continued.

For them, such news undoubtedly greatly strengthened the cohesion of Li Xiao's retainers.

Good things came one after another, Li Xiao had just learned the news that he was a father, and with the help of three hundred people, the speed of building the city was further accelerated.

Most of the outer maru defense has been completed, and the construction of the Jinshomaru military ration warehouse and the castle tower is in progress one after another.

Just when Li Xiao saw the dawn that Shengang City was about to be completed on schedule.

Sister Koji Yoshiyori finally couldn't sit still, he must not sit idly by, the Takeda family was established in Hida Country, such a bridgehead, to threaten his position as the head of the Hida Country.

So Sister Koji Liangyori mobilized 700 troops in the territory and personally attacked Li Xiao's Shengang City.

Li Xiao immediately learned the first-hand news through the report of Yokotani Yukishige's ninja people, so he immediately mobilized the peasants and soldiers to prepare for war.

Although he did not have expectations, Li Xiao still sent a letter to Jiangma Shisheng on the way, asking him to send troops to help in the battle, but sure enough, Jiangma Shisheng refused Li Xiao's request.

The reason is that he has occasionally felt unwell recently, so he can't bring troops to help, and deliberately used a sarcastic tone to boast of Li Xiao's bravery, saying that the 8,000 people of Uesugi Kenshin on Shiragen Mountain were defeated by Li Xiao, and the mere 700 troops of Sister Xiaolu's family are nothing.

And at the end of the letter, he also wished Li Xiaoma success.

Li Xiao sneered silently when he saw this letter, anyway, the mountains are high and the rivers are long, and the account with Jiangma Shisheng will be calculated sooner or later, and there will always be a day when he will be able to drink his own footwashing water.

So at the moment, Li Xiao immediately mobilized to prepare for war, and pressed the only hope of repelling his sister Xiaolu's family on his two hundred standing reserves.
