In that era, there were many ways to build a city. The simpler one was to build a camp based on wood, then apply mud and dry it in air. However, if there were a little resources and time, the city would be built by combining earth and stone structures or wood and stone structures. Of course, the most classic one was Nanjing City built in the Ming Dynasty. It built an amazing city with marble brick and stone structures and glutinous rice juice - but Yu Qiuping certainly did not have such conditions.

Another common way of building a city is to use rammed earth on the inner layer as the wall embryo, and bricks and stones are built on both sides to wrap the soil layer inside, making it a city wall. Yu Qiuping believes that this way of building can also be used to build the Tianshou Pavilion.

This is also the prerequisite for all Yu Qiuping's plans to carry out.

"I'm brave enough to ask your highness to make it clear," Naoe Tadaehiro asked inexplicably: "What is the connection between tumultuous castle and assassination of Oda Nobunaga?"

"That's right, please listen to me to explain slowly." Yu Qiu took a breath and said: "According to our tradition, if a retainer wants to build a city in the area, then all the construction of the city will be left to the retainer. The lord will obtain the right to use the city before the city loses its strategic significance and enter the city to command."

"We want to build a castle in Sumata in Mino's territory. At the beginning, we will definitely be able to build a proposed civil-structured city." Yuqiuhei said as he put his hands behind his back and walked slowly around the house. "But after repelling the possible attack from the Saito family, we will have the opportunity to renovate the city."

"For example, build an exquisite Tianshou Pavilion with earth and stone structure." Yu Qiuping paused and lowered his voice: "If you want to attack Simeono, the lord may have personally climbed up to this exquisite Tianshou Pavilion with his close guards to see the battle situation."

"The conditions required for combustion are combustible materials, air and a certain temperature." Yu Qiuping recalled the knowledge in school classrooms in his previous life.

"If we mix a lot of flammable materials such as gunpowder, sulfur, charcoal, straw and cotton into the soil between the two wall tiles, and then make the inner wall tiles looser to ensure air circulation. Build the entire Tianshou Pavilion into a large gunpowder barrel."

"When the lord brings a group of important members to enter the Tianshou Pavilion and then ignite the fire..." Yu Qiuping said this, but instead turned his eyes to the three subordinates. Naoe Tadae was already sweating coldly, and Masayuki Sanada was also trembling. Even Amano Keito, who was usually calm and composed, frowned at this moment.

The reason why Yu Qiuhei came up with this method was inspired by the incident in the history of his previous life. Akichi Mitsuhide grilled Oda Nobunaga at Honnoji Temple. At that time, Oda Nobunaga only had a few hundred people around him, living in the self-safe Honnoji Temple. Akichi Mitsuhide, who was treacherous, came from the Tamba Kingdom and surrounded the Honnoji Temple. The overlord in the area also fell in the fire.

I can also imitate the Incident of Honnoji and come to the Incident of Sumata Castle.

I will perfectly copy the tragedy of the late Lord of the family being burned to death in Minghai City. However, I will not give you any chance to put out a fire or escape, but will directly make the Tianshou Pavilion explode.

"This method... is really... too..." After hearing Yu Qiuping's plan, Naoe Tadae stumbled to make a comment, but he couldn't find a suitable word no matter what.

No wonder Tadaohei Naoi thought so. Yu Qiuping's plan was too crazy. Throughout history, no one has ever built a Tianshou made of gunpowder to explode and assassinate. This plan sounds crazy and unrealistic.

"Too sensational, or too sensational?" Yu Qiuping helped him add two words. After seeing the latter nodding slightly, he continued to speak: "But theoretically, it is indeed feasible. Don't you believe in the power of gunpowder? Are all sensational plans also come up with people? This is a way to deliver them to the present. If you don't use it, do you have any better ways? You can also propose it."

Naoe Tadaehide and Amano Keito were stunned for a moment and fell into deep thought. After a long time, they had to admit that although this plan was horrifying, it was indeed feasible.

"Maybe we can consider sending ninjas assassin to assassin Oda Nobunaga?" Naoe Tadahei suggested.

"According to our information, Oda Nobunaga is on a very tight guard on weekdays, and many guards and ninjas are guarding each other in the dark, it is probably difficult to succeed." Sanada Masayuki vetoed, "Unless he uses overwhelming force to attack, it is impossible to assassinate him with one or two assassins."

"Then maybe you can fight back on the battle formation and kill him in the chaos?" Naoe Tadaehiro once again proposed a plan.

"It's too difficult. The situation of the war is changing rapidly. Unless I can clearly grasp the direction of the war, it would be too complicated to deploy it in advance," Yu Qiuping shook his head and said, "Besides, the success rate is not as high as I blow up Tianshou Pavilion."

"But your highness's method is easy to leak information." Naoe Tadaehiro still reminded him with some concern, "First you have to get so many flammable materials, and you also have to use them for building a city. The workers who build a city will see it."

"Are flammable? We have bought a lot of gunpowder and sulfur for the training of the iron cannon team, so don't worry." Yu Qiuping nodded, "But the problem you mentioned that craftsmen will see when building a city... is indeed risky."

"This is not difficult." Amano Keito said coldly, "We build a castle in Mino on the other side of Kisogawa, not Ohara under Oda Nobunaga's control. With the ninja alert around, we can avoid Oda Nobunaga's eyes and ears. The workload of building a small Tianshou Pavilion is not very large. It does not require a large-scale employment of people as workers. It only requires mobilizing reliable and uninformed old brothers to build a castle with earth that has been mixed with gunpowder. Even if they see that the composition of those soil is a wrong thing, we will not gossip about it as a secret matter."

"As for mixing a large amount of gunpowder into the soil, the ninjas who are under the water can do it." Sanada Masayuki added, "They will never leak the secrets easily, and I will not tell them the purpose of these soils. I hope your highness will rest assured. As long as the two steps of mixing gunpowder into the soil and building a city with soil will not be allowed to guess the purpose."

Seeing that the risk issues were eliminated one by one, Naojiang Tadaehime was still a little worried. He swallowed, hesitated for a moment, and finally said, "But doing a conspiracy to detonate the Tianshou Pavilion, such a traitor... I'm afraid that it will damage Your Highness's usual reputation. Our brothers Chang Panbei know that Your Highness has done such a thing, it may be very troubled."

Naoe Tadaehide's words made Yu Qiuhei a little shaken. But after a moment of silence, he immediately reached into his clothes and held the ribs left by Toshi Semei. The cold touch spread from the palm of his hand throughout his body, and immediately suppressed his hesitation and confusion.

Over the years, whenever he has shaken his goal of revenge, this ribbed snail that has never been sheathed will be his spiritual pillar. His Highness Sezuna exchanged his life for his life, just to let him complete the unfinished things and take revenge! It was not that he could live comfortably in his enemy's house!

"I understand." Yu Qiuhei looked at Naoe Tadaehide solemnly and nodded miserably, "But I must not let His Highness Sezu die in vain. I must avenge the revenge of His Highness, the family governor."

"Is Your Highness really going to do this..." Naoe Tadaehira was still a little unwilling to accept this plan. "Your Highness... Maybe Oda Nobunaga will die in the battle formation one day, and you don't need to take advantage of the world's tyranny to kill the king. Even if you send assassins to assassinate, you can at least argue that it was not ours, but if you directly detonate the Tianshou Pavilion, your Highness will be the subject of thousands of people!"

"Stop talking, personal guard, I understand what you mean." Yu Qiuhei shook his head firmly, "But this is the best opportunity I can seize now, and I can't afford to fail. Otherwise, how should I face His Highness Sena and His Highness the Lord of the Family?"

On May 1, Oda Nobunaga could not wait to order the entire territory to assemble troops and prepare to attack the Saito family in large numbers. However, the Saito family, which had a covenant with the Hexaki family, moved out the general Ashikaga Yoshiki who was attached to the Hexaki family. At their request, Ashikaga Yoshiki sent an envoy to try to mediate the war between the Saito family and the Oda family. However, Oda Nobunaga, who was proud to swallow Mino, ignored the general's envoy and refused.

On May 9, the Oda family completed the assembly of all its leaders. Oda Nobunaga personally led the 12ooo army to Nitanba County, collecting ferries and wood on the south bank of Kisogawa, preparing to build a floating bridge to cross the river. The Saito family realized that the Oda Nobunaga's visitor was not good this time, and it was not like a small fight. The Nishimino family sent troops together and cooperated with the Saito family's troops to assemble the heavy troops of the 1ooo people and entered the Gewu County on the north bank of Kisogawa. The main force of the Oda family and the Saito family were far away from Kono Island on the Kisogawa River.

At the same time, the Oda family's ranger in Mino area also launched an operation. The Oda army, who became the general of Imoriko, gathered nearly 300 troops, and moved on the east side of the Saito family, threatening the safety of Inabayama Castle. Their existence forced the Saito family to not dare to invest too much force on the beachhead position on the banks of Kisogawa, but had to distribute some of the troops to cover the defense line of Inabayama Castle.

Just when it was confirmed that the main force of the Saito family had been attracted to Kazuo, Yuqiehei also quietly launched an action. The main force of the four small families on the other side of him had been transferred to the Kazuo battlefield, and it might not be possible to help Yuqiehei. The plan of Kinish Hideyoshita asking for help from Kazuo in history is probably impossible to achieve in this life. However, Yuqiehei didn't care. Because he was in Yeli County, he was in the upper reaches of Sumata. He had already reserved a large amount of wood before and immediately dispatched a large number of auxiliary soldiers to weave rafts on the banks of Kisogawa in the early morning, allowing the soldiers and auxiliary soldiers to take torches and ride down the raft. Under his leadership, Takatani's entire army took advantage of the moonlight and headed straight for Sumata.
