Hua An gently put the crushed pill in his hand back into the box, then got up and walked in the direction of the medical hall, he tried his best to persuade Ge Hong to help him test the black powder.

At this moment, in the medical hall, Ge Hong, who had been eating and drinking for more than a month, began to refine the elixir to strengthen his body in return for the care of Hua'an, Huangfu and others.

In Ge Hong's eyes, all kinds of precious medicinal materials can achieve better results after some refining, people can eat to strengthen the body, drive away all kinds of diseases, but in fact, this is just a psychological effect, the medicinal effect of refined pills and unrefined medicinal materials, the difference between pharmacological effects is not very big, and even, refined pills are not as good as medicinal materials that have not been refined at high temperatures.

It can be said that the pill itself has a comforting effect on people's hearts, making people believe that eating him will strengthen their bodies and never get sick, so as to be more confident, so that they will naturally have a good effect on people's bodies, not that the pill itself has any miraculous effects.

When Hua An was still some distance away from the medical hall, he saw wisps of green smoke floating above the medical hall, and after getting closer, he smelled a faint smell of herbs, which was enough to show that Ge Hong was alchemizing in the medical hall.

After entering the medical hall, Hua An walked directly in the direction where the green smoke was rising, and after a few doors, he arrived at the courtyard where Ge Hong was refining the pill.

In the courtyard, there are several alchemy furnaces of different sizes, and several boys are adding firewood to the alchemy furnaces, while Ge Hong is sitting in the pavilion and meditating cross-legged, with his eyes slightly closed, as if he is asleep.

Hua An walked gently to the gazebo and stood beside Ge Hong. But Ge Hong seemed to be unaware of it, and still closed his eyes and meditated.

Seeing that Ge Hong didn't find himself, Hua An also learned Ge Hong's posture, sat down cross-legged opposite Ge Hong, and sat down with his eyes slightly closed.

About two moments later, Hua An heard footsteps beside him, and when he opened his eyes, he saw that it was a boy walking over with a refined elixir.

"Ge Gong, the elixir has been refined." Hua An said softly.

Ge Hong was shocked when he heard this, and hurriedly opened his eyes. Seeing Hua An sitting in front of him. Surprised: "The general is meditating here, and the old man doesn't know, rude, rude." As he spoke, he arched his hand to Hua'an.

Hua An smiled. Said: "This is the end of the book. See Ge Cheng resting on his knees. I couldn't bear to disturb it, so I sat down for a while. ”

"Oh, the general is coming. Is there something going on? Ge Hong asked softly, he had just sent someone to send the pill to Hua An, and Hua An came to find it, and he thought in his heart that Hua An came to him about the pill.

Hua An Zhengse said: "This general is coming, there is indeed an important matter, to discuss with Ge Gong, this matter is related to the lives of the soldiers and the success or failure of our army's siege of the city, and I hope that Ge Gong will help you!" ”

When Ge Hong heard this, he was slightly surprised, and hurriedly said: "If the general has any difficulties, you might as well talk about it, if the old man helps, the old man will definitely do his best." ”

Seeing Ge Hong's statement, Hua Anxin was relieved a lot, paused, pointed to the alchemy furnace in the courtyard, and said softly: "I was going to use this alchemy furnace to refine an elixir that can attack the city, and I hope that Ge Gong will help me a lot!" After speaking, he looked at Ge Hong expectantly.

When Ge Hong heard this, his surprised eyes were about to pop out, after all, when Ge Hong was young, he was also a general of the Great Jin Dynasty, and he also led troops to fight and attack the city, and he was no stranger to attacking the city, as for what Hua An said about using refining pills to attack the city, it was unheard of.

"The general said with a smile, the pill can only strengthen the body and prolong life, how can it be used to siege the city, and the siege should be used to use the cloud ladder hail car, hehe!" Ge Hong shook his head after speaking.

Ge Hong's answer was completely expected by Hua An, after all, black powder had not yet been invented at this time, and Ge Hong naturally could not know the huge power of black powder, and Hua An could not directly say the relevant knowledge of black powder, which would scare Ge Hong stupidly.

Hua An thought for a while, and said: "Ge Gong, the success or failure of the siege is related to the lives of the soldiers, how can this general laugh and not hide it from Ge Gong, this general has been instructed by a master, only nitrate, sulfur and charcoal powder can be refined to make an elixir that can crack, once this elixir is refined, it can directly blast a big gap in the city wall, so as to break through the city smoothly." ”

"There is such a thing, so why didn't the general let that master come to refine it?" Ge Hong was a little suspicious of Hua'an in his words.

Hua An pretended to shake his head helplessly, and sighed: "The master is used to being free, and he doesn't want to stay in Nanzheng, how can he be strong." After speaking, he looked at Ge Hong.

In Hua'an's words, there is a great meaning of ridiculing Ge Hong, after all, Ge Hong is also a master of the world who likes to be free and does not seek fame and fortune.

When Ge Hong heard this, he pursed his lips and frowned: "The general is not afraid that the master is casually speaking, in fact, there is no such thing at all." ”

Hua An shook his head and said, "No, Ben will see the master light a pill with his own eyes, and after throwing it out, he will smash all the dead branches, the power is very great, not to be underestimated!" ”

"Oh, there's such a thing." When Ge Hong heard this, he believed it a little.

"If Ge Gong can refine this kind of elixir, I will have a greater chance of winning in the Northern Expedition to the Central Plains in the future, I don't know if Ge Gong can wish Ben a helping hand." Hua An asked softly, the tone in his words was completely negotiable, without any coercion, but it made Ge Hong embarrassed to refuse.

Ge Hong nodded, and said softly: "It's okay for the old man to be idle, but you can give it a try, but as for whether it can be refined, the old man can't guarantee it." ”

Hua An knew that Ge Hong would answer like this, and he couldn't help but be very happy in his heart, paused, and said: "The moment the alchemy furnace in the courtyard is shattered, it is the time when Ge Gong succeeds, and I will believe that Ge Gong will definitely succeed." ”

"Huh! The general can rest assured, the old man will do his best. Ge Hong replied with a fist.

Hua An nodded, and then, he said about the things that need to be paid attention to when refining black powder, especially that there should not be too many at one time, otherwise the power of the explosion will be too great, and it may cause the consequences of Yan zhòng, and Ge Hong also agreed one by one.

In fact, to test black powder, you only need to adjust the ratio of charcoal, sulfur and nitrate, as long as you are patient to test, you will always succeed, even if you don't let Ge Hong do it, let ordinary soldiers test it, but Ge Hong is familiar with alchemy after all, so it is more secure to let him test.

After explaining the matter of testing black powder, Hua An left the Literature Museum and returned to the Assassin's Mansion to deal with some things that had to be dealt with.

#####

In the direction of Liangzhou, the main army of 50,000 of Ma Qiu and Sun Fudu left the city of Caohan, where the elite soldiers of the Liang State were stationed, and attacked all the way to the west, successively breaking through several cities in Jincheng County and Guangwu County, and stationed in Hongchiling, which was not far from Guzang, and the troops pointed directly at Guzang, the capital of the Liang State.

For Zhao's army to arrive at Hongchiling within a few days, the whole city of Guzang was shocked, and even a little panicked, and the whole court was shrouded in a tense atmosphere.

In order to resist the offensive edge of the Zhao army, Zhang Chonghua, the king of Liang, sent a multi-way army to fight against Ma Qiu, but they were all defeated one by one.

In the mansion of the King of Liang in Guzang City, Zhang Chonghua, the King of Liang, was discussing the strategy of retreating with the important ministers of the court in the main hall.

Some built tens of thousands of troops from Shazhou in the west to return to Guzang to strengthen Guzang's defensive forces, some built and moved the capital to avoid the advance of the Zhao army, and some moved back tens of thousands of elites from Caohan, abandoned Hezhou, and defended Guzang with all their might.

For all kinds of subordinate buildings, after careful consideration, Zhang Chonghua, the king of Liang, always felt that it was not very suitable, and transferred back tens of thousands of troops to Shazhou, in case Tuyuhun annexed Shazhou, Liangguo would lose half of the western part of the country, and transfer back tens of thousands of elites in Caohan City, and Hezhou would be equivalent to giving up to Zhao Jun, both of which were cutting Zhang Chonghua's heart.

Since the founding of the Liang State, Guzang has always been the capital of the Liang State, and moving the capital without authorization in order to avoid the enemy will shake the confidence of the soldiers and people in the country, and the consequences will be even more unimaginable, and even Zhang Chonghua's throne may be replaced by someone in the family.

Not long after succeeding to the throne, Zhang Chonghua, whose foundation was not very solid, felt that only by completely repelling the attack of the Zhao army could he establish his prestige, so that the soldiers and people of the entire Liang State could support him, and his position as monarch could be maintained for a longer time.

Zhang Chonghua stared at everyone and said loudly: "My Liangguo has more than 100,000 soldiers, and Guzang still has tens of thousands of elite soldiers, can't even deal with a little Maqiu, which general dares to lead the troops to a decisive battle with Maqiu." ”

Many generals in the hall were afraid of the spirit of the Maqiu army, and they did not dare to take over the mission of leading the troops into battle.

Seeing that all the generals were afraid of the enemy like tigers, Zhang Chonghua couldn't help but be very angry, got up with his sleeves, and prepared to leave the hall.

Minister Zhang Tan stepped forward, hugged his fists and said: "Your Majesty, the minister recommends one person, which is enough to repel Ma Qiu." ”

When Zhang Chonghua heard this, his face softened slightly, and he hurriedly asked, "Who do you recommend?" ”

Zhang Tan hugged his fists and said: "Back to the king, the minister recommended Xie Ai, who has both humanities and martial arts, and has the talents of Le Yi and Han Xin, if Xie Ai leads the troops to fight, he will definitely be able to repel Ma Qiu to ensure the peace of my Liang country." ”

Seeing that the person recommended by Zhang Tan was Xie Ai, Zhang Chonghua was very unhappy, you must know that Xie Ai was the chief bookkeeper at this time, and he belonged to a civilian official, and he had never had the experience of leading troops to fight, so let a white-faced scholar lead the troops to fight against a famous general of Zhao like Ma Qiu, and the hope of winning can be imagined.

"Zhang Aiqing, Xie Ai is just a master bookkeeper, let a white-faced scholar lead the troops into battle, wouldn't it make Ma Qiu laugh, is it true that I am a dignified and cool country, and there is no general?" Zhang Chonghua said and looked at the generals under His Royal Highness.

When all the generals in the main hall saw this, they all bowed their heads and said nothing. (To be continued......)
