Helian Han knew that it was extremely difficult to resist the attack of the old Mao army, and once again asked Helian Shantou to Juyanhai for help. Xuan Qi also knew how difficult it would be for Ju Yanhai to face the attack of the old Mao people alone if the Xiongnu did not destroy the country, so he immediately agreed to send troops.

Since Helian Lu did not go south for the time being, but tried his best to take down the Khan's court first, Xuan Qi's 100,000 cavalry marched north along the western foot of Hangai Mountain and went straight to Tayatia. When Helian Lu heard that Xuanqi's army had arrived in Tayatia, he temporarily stopped the attack on the eastern front, personally led an army of 300,000, and began to enter the Hangai Mountains, preparing to avenge Xuanqi's revenge for destroying his 150,000 army.

The Xuanqi army set up a large camp in Tariat, and first sent a large number of scouts to the north to investigate the news. After the scout came to report that Helian Lu personally led an army of 300,000 and had already attacked the Tayatia, Xuan Qi made an unexpected decision to lead the army overnight and advance to the west.

Xuanqi bypassed Helianlu's army and began to move north, and three days later he had reached Bretai in the upper reaches of the Idel River. The defender of Bretai was Helian Han, the second son of Helian Lu, with less than 20,000 defenders. The Xuanqi army suddenly appeared opposite the city of Bretay, and immediately scared Helian Han into a cold sweat, and while gathering the army to resist, he urgently asked his father Helian Lu for help.

Xuan Qi intended to train Helian Nian, and when he arrived at Bltay, he simply handed over the army to Helian Nian's command. Helian Nian faced the war for the first time, but he was nervous and excited, and gathered a group of generals overnight to discuss the attack on Bretay. The city of Bretay is close to the Idel River, and is surrounded by high mountains on both sides, but it is only a flat river to the north, which is conducive to the siege. After looking at the topographic map, Helian Nian began to assign the tasks of the generals without stopping.

Helian Nian led an army of 50,000 to the west in the night, wading across the Idel River more than 20 miles upstream from Bretay, and slowly approaching the north gate of Bretay. The remaining 50,000 troops, of which 30,000 also began to cross the river, approaching Bretay City from both sides, leaving only the 20,000 troops led by Xuan Qi, facing Bretay City across the river.

Helian Nian led the army, and finally arrived in the mountains northwest of the city of Bretay in the afternoon of the next day, and the low walls of the city could already be seen in the distance. Looking at the last dangerous pass that was only five or six miles away from Bretay City, Helian Nian knew that as long as he won this dangerous pass in front of him, the army would be able to face Bretay City directly. Helian Nian was not in a hurry to advance, but ordered the whole army to rest in the mountains, and at the same time sent scouts to prevent the whereabouts of the army from being known by Helian Han.

At dawn the next day, Xuan Qi began to order the armies on both sides of Bretay City to feign to attack the city according to Helian Nian's plan. Helian Han relied on the danger of the mountains on both sides, and with only 10,000 defenders, he stopped Xuanqi's 30,000 cavalry outside the city. As Xuan Qiqin led the remaining 20,000 troops to cross the river, Helian Han had to transfer back 3,000 of the 5,000 defenders who had returned to the dangerous pass northwest of Bretai City to help defend the city.

Hearing the report from the scout, there were only 2,000 defenders in front of him, so Helian Nian sent 5,000 soldiers who had already been prepared to climb up the mountain beams on both sides of the danger, and he personally led the army and slowly approached the danger. The commander of the thousand horsemen guarding the pass heard the rumbling hooves of horses from a distance, and was suddenly startled, and when he rushed to the wall, the dense cavalry had already appeared in front of him.

The commander of the thousand cavalry naturally knew that if this pass was lost, Bretay City would not be able to resist the impact of so many cavalry, so he immediately ordered the defenders to strictly guard the dangerous pass, and at the same time urgently asked for help from Bretay City. Just as the reinforcements were hurrying away, Helian Nian had already ordered the army to start attacking the city.

When the commander of the thousand cavalry was about to order the whole army to suppress the cavalry under the pass with bows and arrows, countless heads suddenly appeared from the mountain beams on both sides, and countless sharp arrows shot out in parallel, which immediately pressed the two thousand defenders to the point that they did not dare to raise their heads at all. The dangerous pass is parallel to the mountain beams on both sides, but the number of people is much worse, but this time it can only watch countless cloud ladders begin to erect the dangerous pass, and the soldiers of Ju Yanhai have already started a full-scale attack.

As the first Juyanhai soldier rushed to the wall, the old Mao soldiers guarding the pass finally began to retreat, and the disparity in strength made the old Mao soldiers have to give up the dangerous pass, and under the order of the thousand cavalry commanders, they began to scatter and flee. The gate rumbled open, and countless cavalry rushed in, quickly passed through the dangerous pass, and appeared outside the north gate of the city of Bretay.

Seeing a large number of Juyan Sea cavalry appearing at the north gate, Helian Han suddenly panicked, and was surrounded on all sides, but he didn't know which direction to break through. However, Helian Nian did not hurry, and ordered the army to approach step by step, and when it was within the range of the bow and arrow, countless sharp arrows passed through the low city wall and shot into the city of Bretay.

In just a few moments, a group of old soldiers had fallen on the city wall, and the rest quickly retreated towards both sides of the city wall and the city. Under the suppression of the rain of arrows, Helian Nian's army quickly occupied the walls of the north gate and opened the north gate. The iron hooves flew and rumbled through the north gate into the city of Bretay.

The city of Bretay, which had only more than 10,000 defenders left, could not resist the impact of iron hooves at all, and was soon lost. Countless old Mao soldiers began to rush to the east of the city, wanting to leave the city from the east of the city and flee into the mountains. However, the 15,000 army of Iligo gave up the attack on the city wall and began to use bows and arrows to shoot the old Mao soldiers who rushed out of the city gates.

As Helian Nian's army approached the east gate, the battle gradually subsided. In this battle, almost all of the 18,000 Bretai defenders were wiped out, and only more than 1,000 fled into the mountains. And Helian Han himself was shot by a random arrow in the chaos of the army, and died under the horse's hooves.

When Helian Lu arrived in Tayatia, he was in a daze, and he didn't know where the Xuanqi army had gone. Helian Lu, who was a little at a loss, finally received that the Xuanqi army had been heading towards Bretay two days later, and immediately secretly screamed that it was not good, and immediately ordered the army to start pursuing Bretai City.

When the army was still halfway, it ran into a cavalry squad sent by Helian Han to ask for help. Helian Lu, who was deeply disturbed, did not care much, and immediately ordered the army to speed up. At noon the next day, Helian Lu's army was no more than a hundred miles away from the city of Bretay, but the news came from the front that the city of Bretai had been breached, and his beloved son Helian Han had died.

When Helian Lu heard that his beloved son was dead, he immediately fell off his horse with a thud and fainted, and several pro-soldiers hurriedly stepped forward to help Helian Lu up. When Helian Lu woke up and cried for a while, he immediately ordered the whole army to advance at full speed, vowing to capture Xuan Qi and avenge his beloved son Helian Han.
