At that time, all the support of Yong Yulu's body was on this leg, and Yan Rong swept towards his support leg with a cold swing, forcing him to force a little more on one foot, and his body jumped up high to avoid Yan Rong's stick.

Yan Rongren was still lying on his back on the ground, seeing Yongyu Lu's body vacated from the ground, so he saw the right time and threw the stick, and the mace weighing about forty catties flew straight to Yongyu Lu's waist and abdomen with a gust of cold wind.

If this stick hits, even if Yong Yulu is not stoned to death on the spot, he will be seriously injured. Yongyu Lu was in mid-air, seeing a black thing flying towards him from under him, he secretly screamed in his heart, and he didn't have time to react more in his eagerness, so he had to stretch out his palms and slap outward.

The mace is so named because it is covered with iron spikes as sharp as wolf teeth. Although Yong Yulu's palm power was amazing, when his body was in the air, he stretched out his palms and struggled outward, and he could push out the mace that Yan Rong threw at him as a hidden weapon, and his own two palms were also hit by the iron spikes on the mace, and the palms of both palms were pierced by the iron thorns, and the blood immediately flowed down from the palms.

"Okay, you rat who hurts people with tricks, leave and take your life!" Yongyu felt that the palms of his two palms hurt his heart, and when his feet landed on the ground and he looked down, he found that his palms were pierced by his mace with two big holes, and he couldn't help but be angry and anxious, shouting and striding forward, he was going to fight with Yan Rong.

At this moment, there was a string of gongs on Wuyuan City that sounded gold and collected troops.

When Yong Yulu heard the sound of the gong, he tried his best to suppress the fury in his heart and stopped, turned his head to look at the city tower, but saw that under the light of the fire on the tower of Wuyuan City, a large banner of the Tuli Khan had been raised.

Reinforcements have arrived in the city, and my uncle is ordering me to collect troops and return to the city! Seeing that his plan to delay the army had worked, Yong Yulu immediately turned his anger into joy, stretched out his hand that was still bleeding and designated Yan Rong, and shouted loudly: "It's getting late today, let you live one more day, and take your life tomorrow!" With that, he turned and walked towards his formation.

Yan Rong was still about to chase, but was stopped by the sergeant behind him and reminded him: "General, a big banner has been raised on Wuyuan City, as if reinforcements from the Turks have arrived." ”

Only then did Yan Rong notice that there were indeed many differences between Wuyuan City and the daytime, not only was the new Daxu flag raised, but there were also a lot more soldiers defending the city than before.

"This guy invited me to fight, and he really wanted to delay the hour and wait for reinforcements!" Yan Rong suddenly realized that he had fallen for the other party's delaying tactics, and he couldn't help but regret it.

For the next three days, Yan Rong commanded the vanguard army of the Sui army, and launched dozens of rounds of attacks on Wuyuan City in turn, but in the middle of the city, Luo Yu led more than 10,000 reinforcements to unite with Yongyu Lu's troops, which greatly strengthened the strength of the city.

Just when the two armies were unable to hold each other, Yang Shuang, the king of Wei, led an army of 50,000 to rush outside Wuyuan City.

Yang Shuang led his army north out of Yanmen Pass this time, and the purpose was very clear: he wanted to take advantage of the opportunity of the main Turkic force to advance westward, quickly capture Wuyuan City in the Turkic territory with nearly ten times the superior force of the enemy, and directly threaten the location of the Turkic Great Khan's tooth tent - Dujin Mountain. Therefore, as soon as he led his army out of Yanmen Pass, he issued an order to the vanguard general Yan Rong to immediately launch an attack on Wuyuan City. At the same time, he led the main force of the Chinese army, and after only one day of rest in Baidaozhou, he wanted to rush to reinforce Yan Rong's headquarters and break through Wuyuan City as soon as possible.

When Yang Shuang was anxious to lead his army to Wuyuan City non-stop, Zhou Shao, another marching commander under his command, reminded him: "Marshal, Baidaozhou is the only retreat route for our army to Yanmen Pass, and we must not fall into the hands of the Turks and make our army a lone army." The last general is willing to lead 10,000 horses and horses to garrison Baidaozhou as a backup for the whole army. ”

Yang Shuang knew that Zhou Shao was a serious person and was good at scheming, and he thought that the Turkic people and horses of Luo Yu and Yongyu Lu were added up, and there were less than 20,000 people, even if he was invited by Zhou Shao, leaving 10,000 horses to guard Baidaozhou, with 70,000 soldiers and horses, it was enough to break through Wuyuan City, and then capture Dujin Mountain, so he agreed to Zhou Shao's request, and ordered him to lead 10,000 horses to garrison Baidaozhou, and he commanded 50,000 Chinese troops, and rushed to Wuyuan City outside the starry night to meet Yan Rong's vanguard troops.

Yang Shuang listened to Yan Rong's report on the siege of the city a few days ago in the big tent of the Chinese army outside Wuyuan City, pursed his lips disdainfully, and said to Yan Rong: "Since you defend yourself that it is because of the Turkic reinforcements in the city, the siege army is insufficient, and you have not been able to attack the city for many days, I will hand over 20,000 horses to you, and break through Wuyuan City within three days, otherwise you will be willing to be a military lawyer, what do you think?" ”

Yan Rong has followed Yang Shuang for many years, and knows the temper and temperament of His Royal Highness King Wei: Yang Shuang seems to be lenient and casual, but when he leads the army to fight, he can't rub half a grain of sand in his eyes.

"Please rest assured, if you can't capture Wuyuan City within three days, I'm willing to come and see you." Yan Rong patted his chest and promised Yang Shuang.

He added 20,000 new troops to attack the city, and Yan Rong himself made a promise to Yang Shuang to capture Wuyuan City within three days.

This time, Yan Rong also changed his previous strategy and used the "Diggers Army", while he himself led the soldiers to attack the city fiercely, he secretly sent an order to the generals, ordering the "Diggers Army" to take advantage of the fact that the defenders of the city were attracted by the siege troops to dig a secret passage and go directly to the root of the city wall.

When it was dark that night, Yan Rong personally led a group of men and horses, with ladders and other things used in the siege, sneaked all the way from the dark passage, came to the root of the city wall, under the cover of night, quietly erected more than a dozen cloud ladders, led by Yan Rong hundreds of daredevils, and people unknowingly touched the wall of Wuyuan City.

When the Turkic defenders on the city found that an enemy army had come to the city at night, Yan Rong had already taken the lead, struggled to cut down several defenders of the city, and commanded this daring army to fly down the city wall, kill the Turkic soldiers guarding the city gate, and open the south gate of Wuyuan City. The main force of the Sui army, which had already been ambushed outside the city, saw that the city gate had been opened, shouted in unison, and poured into the Wuyuan City like a tide.
