The news that the Xiongwu army and the Xiong Zhen army were blocked in the pottery was transmitted back to Crouching Tiger, Zhao Xing was very surprised after learning about it, when he carefully read Xu Shu's report, he knew that Zhang He had already operated the pottery city into an iron bucket array, if it was a hard attack, I am afraid that the Xiongwu army and the Xiong Zhen army would be disabled in order to take it. This is obviously not in line with Zhao Xing's military thinking of concentrating superior forces to annihilate the enemy, so the plan to attack the pottery was temporarily put on hold.

Zhao Xing immediately sent letters to Zhang Liao, Xu Shu, Li Jinwu and others, adjusting the strategy of attacking Jizhou. Zhao Xing demanded that Zhang Liao lead his army to completely occupy Zhao State, and stationed the dragoon army in Handan, which was 90 miles north of Yecheng in Wei County, to completely cut off the connection between Wei County and Xiatao; ordered Li Jinwu's troops to be stationed outside Xiatao City and implement a strategy of besieging and not attacking Xiatao City; ordered Xu Shu to lead Xiong Zhen's army to make a detour to the east to attack Anpingguo, and continued to advance his troops in the direction of Qingzhou, striving to open up the passage between Youzhou and Qingzhou.

Since Zhang He is good at defense, Zhao Xing left 30,000 troops to accompany Zhang He, and when the Jin army conquered the entire territory of Jizhou, Zhang He was surrounded in the city of Liao Tao and became a turtle in the urn, and it was not difficult to handle it.

For the Jin army pressing forward step by step, Yuan Shao was as anxious as an ant on a hot pot. Just when he was about to despair, Zhu Jun led 50,000 southern troops and finally arrived in Yecheng, Cao Cao sent the general Xiahoudun to lead 20,000 elite soldiers to reinforce Guantao in Wei County in time, with the addition of this 70,000 army, plus Yuan Shao's 20,000 elite troops stationed in Yecheng, there are now 90,000 horses in Wei County, and the footsteps of the Jin army to continue to move south have been blocked.

Zhang Liao learned that Zhu Jun had led an army to help, so he moved the dragoon army stationed in Handan to the north, and finally stationed in Guangping. Xu Shu's Xiong Zhen army destroyed the city all the way in Anping, and finally reached the area of Guangzong, echoing with the dragoon army from east to west, and formed a confrontation with the coalition forces in Wei County.

At this point, the Jin army won one after another, and had controlled two-thirds of the counties in Jizhou, but it did not completely annihilate Yuan Shao's main force, so it had not yet reached the set combat goal. Yuan's army continued to shrink, and now with the cover of several big cities, it will not be wiped out for the time being, but the people are panicked and have no fighting spirit.

Just when Yuan Shao was thinking hard about the strategy of counterattacking, the arrival of a person gave him hope.

This man's name is Yu Ji, and he is a Taoist priest who has traveled all over the world, and is proficient in all kinds of illusions and refining pills. At the beginning, Yu Ji claimed to Yuan Shao that he could help the Yuan family defeat Zhao Xing, Yuan Shao only thought that this Taoist priest was talking crazy, and wanted to let people send some entanglements to Yu Ji to blast away, but Yu Ji took out a thing, and after saying the purpose, Yuan Shao was ecstatic, and then treated him as a guest.

What Yu Ji showed Yuan Shao was nothing else, but gunpowder that he had stumbled upon during the alchemy process. In ancient times, the production of black powder was not profound, and the main raw materials were saltpeter, sulfur and charcoal, and it was not impossible for Yu Ji, a Taoist priest who liked alchemy, to discover the formula of gunpowder. It's just that the gunpowder formula discovered by Yu Ji is still different from the thunder currently used by the Jin army, and the key lies in the proportion of the three raw materials.

The reason why the old Taoist Yu Ji came to see Yuan Shao and showed him the black powder that burned with amazing power was because preaching was not allowed in the Jin Kingdom, and the Taoist priests who pretended to be gods and ghosts and the monks from the Western Regions were all expelled from the country, which made Yu Ji very angry. If Zhao Xing wins the world in the future, won't a Taoist priest like Yu Ji have no place to stay? Therefore, Yu Ji wants to help Yuan Shao fight against Zhao Xing.

Yu Ji taught all the methods and proportions of gunpowder to Yuan Shao's craftsmen, and only asked Yuan Shao to allow him to preach and collect people in Jizhou in the future, and Yuan Shao naturally agreed.

After bidding farewell to Yuan Shao, Yu Ji went south to Yanzhou to meet Cao Cao and made the same request. Cao Cao had long been coveted by the powerful thunder possessed by the Jin Kingdom, and now that he had the opportunity to obtain the method of making gunpowder, he was naturally overjoyed, and agreed to Yu Ji's request without hesitation.

Yuan Shao and Cao Cao obtained the recipe for making gunpowder, and immediately mobilized all their craftsmen to start producing black powder in large quantities. As long as this secret weapon is in hand, it will be impossible for the army of the Jin Kingdom to be invincible with thunder in the future. The appearance of the old Taoist Yu Ji shortened the distance between Zhao Xing and Yuan Shao and Cao Cao a lot.

It didn't take long for Yuan Shao's craftsmen to imitate an earthen bomb similar to a thunderbolt, although the power was smaller than that of the Jin Kingdom, but as long as the number was guaranteed, it could also collapse the city gate and blow up the people and horses.

After mastering this life-saving weapon, Yuan Shao followed the advice of his advisers, and did not rush to regain the lost territory, but deliberately began to secretly produce black powder and imitation thunder in large quantities, preparing to accumulate a certain amount and give a huge counterattack to the Jin army invading Jizhou.

Zhu Jun accidentally learned that Yuan Shao was ordering someone to make black powder, so he immediately revealed the matter to Lu Zhi in the court, and Lu Zhi relayed the shocking news to Liu Bei. Although Liu Bei had never seen the Jin army use the thunderbolt with his own eyes, he had heard the story of Zhao Xing blowing Zhang Jiao into the sky with a snap of his fingers, so he immediately excluded the envoy to contact Yuan Shao and asked Yuan Shao to share the black powder technology he had mastered.

Yuan Shao refused at first, and made excuses to prevaricate, but Liu Bei secretly found out that Yuan Shao had seen the old Yu Ji, so Liu Bei directly sent someone to intercept Yu Ji who was about to go to Jiangdong on the way, and asked Yu Ji to invite him to Luoyang.

In fact, after Yu Ji left Chen Liu to say goodbye to Cao Cao that day, even if he walked south, he should be almost in Jiangdong, how could Liu Bei send someone to intercept him. Yu Ji did not go directly to Liu Bei, but secretly spread the news, and finally caused Liu Bei to send someone to chase him, but what he did was just a "name".

Yu Ji knew that if he wanted to develop more Taoists and believers, he had to make the Han court admit that the morality he preached was not the same thing as the Taiping Tao advocated by the Yellow Turban Moth thieves, and that his morality was legitimate and should even be protected by the government. And Liu Bei is the key person to realize Yu Ji's wishes, as long as Liu Bei comes forward to say that the emperor will be enshrined as a national teacher, then in the future he can preach and accept disciples in a bright and bright way, and carry forward Taoism.

In Luoyang City, Liu Bei met the old Taoist Yu Ji and asked Yu Ji to hand over the production method and formula of black powder, and Yu Ji put forward the request that he had already thought of. After Liu Bei repeatedly verified that the "Taiping Sutra" preached by Yu Ji was not the same thing as the "Taiping Technique" preached by the demon Zhang Jiao, he met with Liu Wei in private, and Yu Ji's ability was revealed, suggesting that the Son of Heaven should make Yu Ji a national teacher, and allow Taoist disciples to preach and accept disciples in the territory of the Han Dynasty and build alchemy.

Liu Bian refused at first, and was very jealous of Taoism, for fear that Yu Ji would be the second Zhang Jiao. Later, after Liu Bei's explanation, he learned that the Sanqing Patriarch believed in by Yu Ji and the true god of Zhonghuang Taiyi believed by Zhang Jiao were not the same thing, so he agreed to Liu Bei's suggestion.

Lao Dao Yu Ji once alarmed Liu Bei, so he completed a gorgeous turn and became the national teacher of the Han Dynasty, this method even Zhao Xing smacked his tongue after hearing about it.
