Fang Jinzhi left angrily. Cai Yan warned her not to attack Hangzhou earlier. Now the Holy Church has destroyed the foundation of the Cai family's business, and the inexplicable crisis has made the young women feel uneasy.

Seeing Bao Daoyi and Fang Jinzhi leave, seeing everyone silent, Fang La felt a little regretful, and did not want to offend the Cai Mansion too much, but Cai Jing offended too many people at the bottom, and Cai Yan was always rude to the Holy Church and arrested the brothers in the church...

Millions of church members, countless people cried and shouted that they would destroy the Cai Mansion. What can I do as the leader of the church? The reason for this rebellion is "Hua Shigang". If I don't attack Hangzhou and kill Zhu Xie, who was in charge of the matter, how can I convince the millions of brothers?

Fang La thought of the helplessness, but after all, she was worried about the scene under Jiangning City, and couldn't help but look at Wang Yin, who was secretly developing gunpowder.

"Can gunpowder be developed?"

Fang La spoke, and everyone in the hall looked at the silent Wang Yin...

"How much gunpowder has saltpeter prepared? Is it enough to break through Chengde and Xiuzhou city walls?"

Wang Yin thought for a while and said, "The south of the Yangtze River is humid, hot and rainy, and only Sichuan and Sichuan produce more saltpeter. The Shenggong also knew that the Song court no longer allowed merchants to sell saltpeter privately. The Jiangnan saltpeter was also transported into Jiangning, and transferred from Jiangning to Kaifeng. So we didn't get a lot, only enough to prepare two thousand kilograms of gunpowder."

Fang La frowned slightly, feeling that the two thousand pounds were less, and sighed: "There is less gunpowder. If the brothers can take down Chengde and Xiuzhou, the Holy Church will open up the Suzhou and Huzhou channels, and you can meet with the Suzhou and Huzhou brothers."

Fang Qifo agreed: "What the Holy Lord said is that the road to the passage is one. Secondly, there are two mountains in Zhenjiang. As long as the Zhenjiang ships are taken, we will block the river. Kaifeng will not be able to attack us easily. Thirdly, when the Cai family could break through Jiangning City with gunpowder, we could do the same, and then we could get the storage of saltpeter in Jiangning City. With enough saltpeter, Jiangnan would be captured by the Holy Church in one fell swoop!"

Fang Fei nodded and smiled, "Even if the Cai family has some skills, why didn't they run to Nanyang? How could they compare to our millions of church members? Jin Zhi was too worried."

Everyone let go of their worries. In the past, they might have been a little worried about Fang Jinzhi's words and were worried about being attacked by the court, but now the Holy Church also has gunpowder, so what are you worried about?

As Cai Yan guessed, the people living in this land have always been pragmatists. As long as there is a strong demand, even if things that seem difficult will break through in a short period of time.

The gunpowder formula in "The General Law of Wu Jing" has taken a detour. Adding grease to "charcoal, sulfur, saltpeter" and adding messy things will only reduce the burning speed of gunpowder, which will not reach the point where the explosion hurts people. The people of Song love luxury and need more fireworks to celebrate many festivals, which hindered the improvement of gunpowder. It was not until Cai Yan broke through Jiangning City with gunpowder and defeated Japan with his palm thunder, that the world realized the power of gunpowder, so that the court and the people developed gunpowder in private, and gradually abandoned the fireworks path of "extending the time of splashing" and went in the right direction.

The direction is right. All the oil and fat materials in the gunpowder formula of "Wu Jing Zongyao" are abandoned, and only the three materials "charcoal, sulfur, and saltpeter" are retained, which can reach the level of gunpowder explosion. However, this does not mean that the best formula of gunpowder can be produced. It takes time. Even so, there are powdery refinement, as well as the problem of deposition and uneven mixing of saltpeter in the gunpowder, causing insufficient power... etc.

The demand for fireworks in this era is to extend the time of spending as much as possible to achieve money-saving and dazzling effects. This is a subversive difference from the violent combustion in a short period of time to reach an explosion and injuring gunpowder. It is already extremely rare to be able to recognize this and completely change your thinking. Because of technical shortcomings, it is not possible to fully understand the principle of gunpowder explosion. Even if someone tries to get the best ratio, the power of the explosion will vary greatly due to uneven mixing and easy to tide.

At first, Cai Yan faced this kind of problem, but after all, he was not a person of this era. Even if he gave some knowledge to the teacher, the direction would never be wrong. The best gunpowder formula, gunpowder crushing, refining, mixing evenly, pressing into cakes, granulation, grinding graphite drums... and so on.

Cai Yan believed that people of this era could develop real gunpowder. In the true sense of artillery and gun guns that appeared in the Southern Song Dynasty, as he knew, it had verified this point. It was a subversive transformation. It was a subversive transformation to realize the difference between the two. As for the best ratio and the development of gunpowder pelletization, he did not believe that the Song people would do this in a short time, and there were also various problems of the use of gunpowder. Of course, the Song people were extremely smart. Through the methods used by Cai Yan in Jiangning, Japan, and Liao, they would also see gunpowder explosion, palm thunder, and the power of cannons, and then conduct imitation research.

But all this takes time, and the Song Dynasty court, Manichaeism, and even the Liao Dynasty, all lacked enough time to develop it.

Cai Yanyuan, standing at the bow of the boat, looked at the sea silently. The whole world seemed to be the only one who existed. He did not notice Zhao Fujin walking behind him. He didn't even notice the heavy feeling on his shoulders before his eyes dissipated and turned around.

Zhao Fujin and Cai Wang are average in age and girls are developing earlier. Both of them have a wealthy family and are not lacking in the nutrition required for development. In terms of height, Zhao Fujin is slightly higher than him at this time.

Zhao Fujin has been suffering from the loss since the first time he met Cai Yan. When the two were together, the princess who should have been arrogant always felt inferior in front of him. Her original joy and innocence have become taciturn.

Looking at the girl who was dodging, Cai Yan tightened her robe on her shoulders with her hands, and then held her little hand and stood at the bow of the boat to look into the distance.

"You don't have to worry, my husband just wants to be alone and quiet."

Perhaps the dark sky was a little cold, Zhao Fujin leaned against him and said hesitantly: "Is it... the Manichaeism rebellion? Will... the death of many people?"

Seeing her a little careful look, Cai Yan unexpectedly hugged her waist and abdomen, allowing her to get closer to herself. Feeling her stiffness for the moment, she sighed: "I think you know the difference between Manichaeism. Chen She and Wu Guang rebelled because of the new military Great Wall, because of Qin's southern expedition of the Manyue, of course, the rebellion of the seven countries, as well as the remnants of the people's livelihood caused by military military force, and the reasons for the poverty and poverty of the people. The Yellow Turban Rebellion and Huang Chao's rebellion were similar. After two or three hundred years of the Han and Tang dynasties, the people were poor, so there was a saying that "The sky is dead, Huang Tian should be established". They just wanted to survive and wanted the court to reduce taxes and exploit some."
