Li Yu approved Ren Qiang's request, and Ren Qiang was ashamed of the snow, and Xuanwu Wei dispatched all of them, leaving the pelvic pass in the northwest of Chaonan County on the third day, and leading the Binshui (Suifen River) up to cross the remaining veins in the northeast of Taibai Mountain into the Duling Water (Duling River) basin, which was not easy to appear in the southwest of Duling City.

The defender of Dusk Ridge City, Yongli, will deploy scouts and sentinels on the first line of Huyin (Harmony) Pass on the northwest shore of Meituo Lake, which is the only place for the Tang army to go north. What he didn't expect was that Ren Qiang would be willing to go near and far, work tirelessly, and venture through the remaining veins of the Taibai Mountain, which is nearly two hundred miles away, and enter the upper valley of the Dusk Ridge River, where the territory of the Funi and the Yanbai Mountains meet.

When the banner of Xuanwuwei suddenly appeared in the southwest of Dusk Ridge City, the defenders of Funi in the city were greatly shocked, and they had not yet received the news that the scouts and sentinels deployed in the area of Huyin (Harmony) Pass reported that the Tang army was heading north.

Yong Liding climbed the city wall in a panic, looked at the Xuanwu guards who launched an attack on Dusk Ridge City with the Meridian, and muttered to himself: "Impossible, how did the Tang Army hide from my dense scouts and sentinels and appear in Dusk Ridge City quietly?" ”

"Meng'an, the Tang Army is a ...... that appeared from the southwest"

Yongli Ding grabbed the collar of Mou Ke, who reminded him, and roared: "Impossible, the southwest direction is the upper reaches of the Dusk Ling River, and the south of the Meituo Lake occupied by the Tang army is separated by hundreds of miles of mountains, there is no road at all, how did the Tang army cross over......"

Yongli Ding's face was deformed by anger, so Mou Ke, who was tugging at his collar, carefully reminded: "The upstream of the Dusk Ridge River is only a few dozen miles southeast of the Suibin River, which flows southeast into the southern plain of Meituo Lake, and the Tang army can go upriver along the river that the Shuibin Water rushes out of. ”

"You ......"

Yongli is extremely fixed, and even the Tang army knows that from the south of the Meituo Lake to the northwest, it can enter the upper reaches of the Dusk River, why didn't his subordinates mention it to him?

hurriedly organized an army to defend the city, but the Tang army rushed to the city. The civil structure was built and was no more than fifteen feet high, where could the city withstand the rapid attack of the Xuanwu Guard, who was bent on shame. After holding out for less than two hours, the city gate was split open by the heavy armored soldiers of the Tang army armed with heavy axes, and the Tang army cavalry swarmed in from the lost city gate.

There were only 1,200 defenders in the city, and the unexpected appearance of the Tang army from the southwest caused the defenders to panic, and the loss of the city gate caused the generals to have no intention of fighting and no heart to fight.

After Yong Liding organized a counterattack to try to recapture the city gate, he did not hesitate to lead the remaining army to flee from the north gate, and then recapture Dusk Ridge City after joining up with the 3,000 reinforcements led by Pinri Suo, who were on the way.

Recaptured Dusk Ridge City, Xiao Hong, Liu Ding and other Xuanwu Wei generals were overjoyed, and said freely: "In this battle, our Xuanwu Wei has been disgraced before, and the reputation damaged by the defeat of the two conquests of the Black Water Warrior will definitely be washed away, and we will never let other armies look down on us again." ”

"It's too early to talk about the shame before the snow, and the reinforcements of Funi are on the way, and they will arrive in Twilight City tomorrow. If our army can defeat the invading enemy, then take advantage of the victory to pursue and cross Wandashan to conquer Qitai City, and lay a solid outpost for the army led by His Highness to go north, then it can be regarded as washing away the reputation of Xuanwuwei. ”

Ren Qiang threw out a sentence out of step and ruined the interest of the generals, who called people to be officials and generals, Liu Ding and the others smiled awkwardly.

Yongli set the rate of more than 800 defeated troops to the north, and met with the reinforcements in the Wanda Mountain.

Pinri learned that Dusk Ridge City was lost, so he decided not to go south, and gave full play to his advantage of being familiar with the terrain of Wanda Mountain, and decided to use the rugged terrain and dense forests as cover in Wanda Mountain to ambush the Tang army entering the mountain.

Of course, the Tang army had been ambushed once in the scriptures, and it would definitely learn a lesson from it, and it must be extremely cautious and cautious when marching.

Pinri wanted to successfully ambush the Tang army again, but his confidence was also insufficient, so he made preparations with both hands, and if the ambush failed, he relied on the dangerous terrain in the Wanda Mountain to block the Tang army and consume its vital strength. Then send a team of men and horses around the rear of the Tang army to attack and harass day and night, in order to exhaust the enemy.

After waiting for a day in Dusk Ridge City, the scouts learned that the Funie reinforcements had retreated to the depths of Wandar Mountain, and Ren Qiang had to change his original plan to easily cross Wandar Mountain after eliminating the Funie army outside Dusk Ridge City.

Without even thinking about it, the Funie army that had retreated to the mountain was waiting in the depths of the mountain for Ren Qiang to lead the army into the trap set by the other party.

However, Ren Qiang had to lead the army through the dangerous Wanda Mountain, so he could only make full preparations before entering the mountain.

The generals of Xuanwu Wei were worried about this, when the danger of Wandashan was not great before, the former Guan Yuan chose to lose the fighter plane, and this time it became extremely dangerous Wandashan Mountain, but Ren Qiang wanted to lead them to risk crossing. A vicious war, a hard war, is inevitable.

When Ren Qiang led his army and was about to enter Wanda Mountain, a team of heralds came on horseback and handed over the latest military orders of King Yan to Ren Qiang.

Ren Qiang opened it and looked at it, standing on the spot.

Xiao Hong, Liu Ding and other generals were surprised, and His Royal Highness gave Ren Du Governor an order, which made him lose his mind.

"Governor Ren, what is His Highness's latest military order?"

Xiao Hong asked tentatively.

General Ren Qiang's order was handed over to Xiao Hong, and he said in despair: "Your Highness led the army to enter the territory of the Funian people from the eastern section of the mountain section from more than 170 miles away from the north bank of the Meituo Lake, and the terrain is gently undulating. Ordered our Xuanwu Wei to make a move to go north to Wandarshan in Dusk City, and attract the soldiers and horses of Funi, without risking to cross Wandarshan. ”

"Your Highness has this order, how can we Xuanwuwei wash away the shame of the past?"

Several generals shouted dissatisfiedly, King Yan's military order was completely different from the battle plan formulated before the expedition, didn't this make their hard work to cross the remaining veins of Taibai Mountain in vain? If you want to contain the Funi army, there is no need to go around such a big circle, and directly besiege the city without attacking, wouldn't the effect of containing the Funi army be better?

"Governor, do we still want to enter Wandarshan?"

"Enter, how can you not enter, how can you attract and contain the Funi army if you don't enter?"

Ren Qiang spoke out angrily and ordered the army to remain unchanged, but the marching speed of entering the mountains slowed down, and it would not be able to walk twenty miles in a day.

Straight to the ambush in the mountains Pinri was as anxious as an ant on a hot pot, scolding his mother. Nearly 4,000 soldiers and horses spent every day in the Wanda Mountains, and the grain and grass consumed was a big burden for the newly established country of Funi. If you continue to consume with Xuanwu Wei, where will you get the surplus food to fight the 20,000 troops led by Prince Tang Yan, who has not yet appeared on the battlefield?

At this time, a terrifying news came that the 20,000 troops led by King Tang Yan did not take the route of Dusk Lingcheng to the north, but poured into the territory of Funi from a gentle mountain pass nearly ten miles wide and gentle in the eastern section of Wanda Mountain, which is now less than one hundred and thirty miles away from Yashan City.

Wanda Mountain runs northeast-southwest, between the coastal plain of Meituo Lake and the plain of the Nahe (Songhua River) basin, and is a natural barrier for the Funi Kingdom to deal with the threat of the Tang army to the north. However, this natural barrier is in the middle of the mountain range, and there is a low and gentle mountain pass that is more than ten miles wide, hidden in the dense forest.

It had not been discovered by the Tang army before, and although there were former Tieli people in the Funi Kingdom, no one had informed the monarchs and ministers such as Nuo Gejiao and Shangmuro Chengding.

Cheng Boxian accidentally discovered this mountain pass when he fled south after his defeat last time, which became the key point for Li Yu to win a surprise victory in the north.

Just as Li Yu was preparing to wipe out the Funi Kingdom entrenched in the valley of the river in one fell swoop, a secret letter sent by Xin'er sent by Yexing made him unsettled.

There were only a few short sentences in the letter: "On April 25, the prince died violently in the Hebi Palace in the eastern capital, and it was rumored that the queen of heaven was killed. Jing Chinese Wu proposed to establish the crown prince, and some courtiers wanted to write to the emperor Tianhou Yan to establish the prince as the prince. ”
