Sun Hui suddenly remembered what it was.

Tribulus terrestris.

Porcelain tribulus terrestris is a gunpowder weapon invented by the Tangut people, made of ceramics, slightly larger than a human fist, the appearance is spherical, the surface is full of nails, filled with gunpowder, after lighting the fuse when used, it is thrown into the enemy army, exploding to kill the enemy, it can be said to be the world's earliest grenade. In the era of cold weapons, it was a powerful (not lethal) weapon.

It is said that when Genghis Khan, a generation of Tianjiao in history, led the Mongolian iron cavalry to attack the Western Xia for the last time, the porcelain thistle thrown by the Western Xia soldiers exploded near Genghis Khan's war horse, and Genghis Khan was thrown off his horse, which was seriously injured and died of illness on the way to withdraw the army. Before his death, he harbored hatred for the Tangut and issued three edicts to exterminate the Tangut: exterminate the Tangut king, the Tangut people, and the Tangut culture. By 1227 AD, Western Xia was finally destroyed by the Mongols.

And now, Sun Hui has advanced the time of the demise of Western Xia by nearly a hundred years, and the weapon of porcelain tribulus terrestris has also appeared in front of him in a different way.

From time to time, the Song cavalry lifted off the porcelain tribulus terrestris that exploded from the horse, and the Western Xia cavalry rushed through the gap in the Song army's ranks like a whirlwind and rushed straight to the hillside.

Wang Yan saw these Western Xia cavalry rushing over, of course he understood what the other party wanted to do, seeing that the other party was about to rush to the front, he suddenly pulled out his saber, shouted, and greeted him with his personal guards.

Seeing Wang Yan personally fighting, the Western Xia cavalry did not throw porcelain thistles again, but pulled out the short sticks on their waists.

The moment the men held the stick in their hands, sparks erupted from the tip of the stick, and then flames erupted, turning the stick into a giant torch.

Wang Yan's guards who rushed in front did not know why, they were all startled, and as soon as the two sides exchanged horses, one of the guards raised a knife and slashed, and a Western Xia cavalry raised a stick to block, and when the knives and sticks intersected, the flames burned the armor of the guard, and the guard's body was on fire.

The guard panicked, and immediately slapped his hand on his body to extinguish the fire, at this time Sun Hui saw that the head of the short stick in the hand of the Tangut suddenly popped out of the blade, and the Tangut stabbed the guard off the horse.

Sun Hui saw that the weapons and combat techniques of these Western Xia cavalry were very strange, and when he realized that it was time to make a move, he roared loudly, swooped down in the air, and spewed flames at the tail of the Western Xia cavalry.

Due to Sun Hui's full strength, the Xixia cavalry closest to him turned into ashes, and the one that was a little farther away was burned to him, detonating the porcelain tribulus terrestris he carried, and one after another exploded into human-shaped fireworks.

Sun Hui flew low and breathed fire, and saw that the thousands of Western Xia cavalry instantly turned into fireworks and firecrackers in Tokyo City, Wang Yan was stunned for a while.

Just when Wang Yan was stunned, a Western Xia cavalry had already rushed to the front, raised a fire-breathing short stick and hit Wang Yan.

Wang Yan knew the power of the "burning stick", and immediately dialed his horse to dodge, the other party missed, and simply threw the "burning stick" to Wang Yan, seeing that Wang Yan could not dodge, Sun Hui was shocked, a sharp arrow flew from the darkness, and hit the "burning stick", only to hear the sound of "ding", and the "burning stick" gave the arrow to the side and fell to the ground.

The Western Xia cavalry was about to rush towards Wang Yan, when another sharp arrow flew and hit the neck of the Western Xia cavalry, and the Western Xia cavalry covered his neck with both hands and fell off his horse.

Sun Hui turned his head to look and saw that Yue Fei was collecting his bow, and then picked up the horse chopping knife and killed the Western Xia people.

Wang Yan glanced at Yue Fei silently and didn't say anything, but Sun Hui knew that at this moment, his heart must be full of gratitude.

Thinking that in the history of the Southern Song Dynasty, these two famous anti-gold generals who had been discordant all their lives have now become good partners and killed the enemy side by side, and formed a friendship of life and death, Sun Hui was full of a sense of accomplishment for a while.

In history, Wang Yan was both civil and military, and when he was in the Song Dynasty, he entered Beijing to respond to martial arts, and tried out Wuyi in front of Zhao Ji. He once followed the seed master to enter the Western Xia twice, and made military achievements. When the Jin army invaded, he resolutely left home to join the army, did not enter the imperial camp, but defected to Zhangsuo, and went to the enemy-occupied area of Hebei to find something to do.

Wang Yan and Yue Fei are partners, which can be called complementing each other. Wang Yan, Yue Fei, Bai Anmin and others gathered more than 7,000 horses, crossed the Yellow River north, entered the enemy-occupied area, and took the initiative to declare war on the Jin army. This was the first time that the Song army took the initiative to counterattack after the fall of the Northern Song Dynasty. The Jin army was caught off guard and was defeated again and again. Minister Wang Yan drove straight in, and for a while, the Song people were greatly boosted. However, they also went deep alone, with no backup. The Jin army immediately transferred nearly 60,000 heavy troops to encircle Wang Yan.

With a military strength of nearly ten to one, Wang Yan had a sense of crisis, and he was forced to build a fortress and close his base. This is true in general, because there is a huge disparity between friend and foe. But Yue Fei didn't think so, he was a unique person, and all the achievements in his life were achieved with inferior troops. In other words, if you can only win with more and less, what do you need to do in the art of war?

Yue Fei did not listen to Wang Yan's moderation, and led hundreds of his soldiers to rush out of the camp and fight a decisive battle with the Jin army. In the melee, Yue Fei captured the Jin Army's Daxu and waved it in all directions, and the army's morale was greatly boosted. He not only broke through the encirclement of the Jin army, but also pursued and killed all the way and occupied Xinxiang County.

The Jin army quickly gathered troops to Xinxiang County, but they were too late, Yue Fei did not think about defense at all, he abandoned Xinxiang and continued to advance north. The next day, when he marched to Hou Zhaochuan, he met the Jin army.

The battle began, Yue Fei had no troops, no geographical advantage, and this army could not rely on any other forces except himself. He rushed to the forefront, with more than ten wounds on his body, and he did not retreat from the bloody battle. Under his inspiration, "all soldiers fought to the death" and once again defeated the Jin army.

Since the start of the war between the Song and Jin, the regular army of the Song Dynasty has been destroyed. Gradually, they summed up the tactics of the Jin soldiers, but in fact, there were no tactics, that is, the quality of the Jin soldiers was too amazing. In the Song and Xia wars, the two armies hedged, and after a few rounds, the victory or defeat would be known, and even until it was dark, the two armies would collect their troops very tacitly and rest for the night. Wait until dawn the next day, and then fight after eating. This is not the case with the Jin soldiers, they are unsuccessful in the first rush, then the second time, and the second time when they are unsuccessful, and the third time, this kind of impact will continue all day and night, and it is a veritable immortality.

What kind of courage and combat effectiveness does it take to defeat such an army, and to defeat it in a row with a force of several hundred men? From here, we can see the characteristics of Yue Fei's conquest, he is brave and decisive, eclectic, daring to do what others dare not do, advancing rapidly on the battlefield, and giving the enemy continuous blows. It's a pity that they have few people after all, and they have no food, which is a headache. Originally, it was within the territory of his own country, but he couldn't find provisions. Reality forced Yue Fei to go back and ask Wang Yan for help.
