The fortress closed has been bombarded once. Shigemasa Itankura is very experienced and deals with it calmly. Even though it has three artillery arrays and bombed some dangerous corners, Shigemasa Itankura is still dealt with with it with ease.

These things are not as capable as Hiromasa Itakura. He does things carefully and does not dare to do anything high-profile.

Tadao Toshi Aoyama was like a hand-off manager. He didn't know what to study in his formation room, and he was indifferent to the artillery fire outside.

Naito Masaka left soon, he needed to report the situation here to Tokugawa Iemitsu, and Tokugawa Iemitsu had too many things to do.

The Ming army's artillery fire continued day and night, and the incendiary bombs burned the fortress more brightly than day. The terrifying explosions made the 80,000 troops in Senei unable to sleep at night and uneasy.

Shigemasa Itakura had experience. At night, he came to the underground house where Tadist Aoyama was located. The explosion was still echoing in his ears. He looked at Tadist Aoyama with a serious face and said, "Izumatsu, you can't continue like this."

Tadatsutsu Aoyama looked at the map in front of him and said, "Is this map detailed?"

Tadsuke Aoyama looked at Tutankura Shigemasa and said indifferently: "You have personally investigated this map?"

Hiromasa Itakura has been closing the fortress for a long time. This map was also made by Tadashi Aoyama. He immediately said, "Yes."

Tadatsutsu Aoyama looked at him, lowered his head and continued to look at the map, saying, "Not bad."

Tadatsuke Aoyama has rarely praised people. If it were usual, Shigemasaki Itakura would have been very happy, but now, his face was full of condensation and said, "No one knows the terrain here more carefully than the vassal lords of the countries of Saikkaido. Now, most of them surrendered to the Ming people. This map is probably of little use."

Tadatsutsu Aoyama stared at the map without responding.

After a while, Hiromasa Itankura raised his head and said, "Now everyone in the Custody cannot fall asleep, and eating and drinking are not good. If this continues, we will be trapped to death."

"What do you think?" Tadatoshi Aoyama said without raising his head.

Shigemasa Itakura was a little careful and said, "The villain suggested that the troops were withdrawn in batches, such as the other side of the shore. It would be enough to stay here for 40,000 to ensure that the samurai will not be exhausted."

Tadatsutsu Aoyama looked at a point on the map, his eyes flashed, and he shook his head and said, "Don't expect that if we withdraw troops, it will shake the morale of the army. The Mingren will not just bombard him. I expect that at most three days, they will start siege the city."

Hiromasa Itankura's mouth moved, bowed, and said, "Izu's eyes are like torch, and the villain is in vain!"

Tadatsutsu Aoyama looked up, looked at him, listened to the rumbling cannons outside, and said, "But there is one thing you are right, we can't be trapped here."

Ichikura Shigemasa looked up at Tadatsuki Aoyama, waiting for his words below.

They had an army of 80,000, which seemed to block the Ming army's advance eastward and set foot on the road to their own islands. In fact, their army of 80,000 was also trapped here. They could neither go out to fight the Ming army in decisively nor waste it indefinitely.

Tadsuke Aoyama did not ask Hiromasa Itak to wait for long, and said in a low tone: "We need a big victory to severely defeat the Ming army's spirit and force the Ming army to stop."

Shigemasa Itankura nodded. Not only did it take time to close the strait, but it also needed food and grass. Edo also needed time to sort out the storm of the emperor's edict, strengthen control over daimyos in various places, collect soldiers, food and grass, plan their own island defense lines, etc.

After a desperate failure, Japan has too many things to do.

Tadatsutsu Aoyama said: "I have a plan in my mind, which requires the cooperation of Ichikura."

Ichikura Shigemasa bowed and said, "Izu stays true to his orders."

Tadao Toshi Aoyama nodded, pointed to a place on the map, and said, "This place is called Fenglinxia. If there is a big fire, it will be enough to destroy 30,000 Ming troops!"

This map was drawn by Hiromasa Itakura himself and was very familiar with everything. Just looking up, I knew where Tadatsushi Aoyama was talking about, but he frowned and said, "Izumo, it's a bit far from here. It's not easy to get over it, and it's too difficult to set up an ambush there."

The place where Aoyama Takashi is pointed at is fifty miles west of Guanmen Strait. It is a steep mountain ridge and a gourd terrain. Once you enter, there will be no road to life at both ends.

But when this place goes from Guanmen Strait, you have to cross the Ming army camp. Moreover, the Ming army openly set up an ambush outside, so how can they go out?

Tadao Toshi Aoyama looked cold and looked straight at him, saying, "If you lie down on the day and go out at night, you can go out along the coast. There are not many people. Each time, two or three hundred people can be more than one thousand people in five days. If you do a little trick, you can pretend to be ten thousand people. If the Ming army wants to make sure that there is no in case, at least 20,000 people will be sent to strangle them."

When Ichikura Shigemasa heard this, he suddenly had an ominous premonition in his heart, saying, "What Izumo said just now was 30,000?"

Tadatoshi Aoyama said: "I am still ambushing people in the building of Houfan, Qianfan and other places. Those who surrendered to the Ming army are not entirely sincere. There are also people I buried. At that time, they will cooperate with you and start a crime in another direction."

Shigemasa Itankura frowned, his eyes flashed, and his face was very solemn.

He understood that Aoyama Tadatsuki wanted him to leave the city and go to the Hulu Canyon!

Once you leave the city, you will never come back!

Tadsuke Aoyama had no time to play a puzzle with him, and went around the circle and said directly: "Ichikura, I hope you can do it well. This is your last chance."

Ichikura Shigemasa's expression was extremely ugly. He finally understood why Tadatsushi Aoyama protected him so many times and kept saving him. He was waiting for today!

——Let him go to die obediently and complete this plan!

Shigemasa Itankura's eyes flashed and his heart surged.

He didn't want to die, but he couldn't refuse Tadatsutsu Aoyama, or in other words, Tadatsutsutsu of Aoyama had some ways to prevent him from refusing!

Looking at the changing expression of Itankura Shigemasa, Tadatsushi Aoyama said, "Let's go tonight."

Hiromasa Itakura's eyes were cold, his face twitched, and his heart was even more entangled as if he had cut it. After a while, he finally bowed stiffly and said, "Hayi!"

Tadatsuto Aoyama nodded indifferently and said, "Listen to me about the detailed plan, remember it carefully and in your mind, and don't trust anyone."

Shigemasa Itankura already had ambition to die, his mind was completely disheartened, and he listened indifferently. As for the aftermath, he had arranged such a thing several times before.

Tadsuke Aoyama pointed at the picture and began to teach Shigemasato Hirosa a little bit.

As a person who has passed through the Toyotomi Hideyoshi era, he has too much experience. Even when facing the Ming army with artillery advantages, naval advantages and strategic advantages, he is still calm and composed.
