"Old boy, is Commander Sun okay?" On the side, Xia Yan, the commander of the Sixty Army, asked worriedly.

"Are you okay? Even if you don't die, you're definitely seriously injured. Commander Xia, Commander Mao, after Sun Shimin takes the Ice General next, you two will immediately take the Ice General out of Caoyi Valley and break through to the south! Now, the life and death of the Ice General is uncertain, I will let the two hundred divisions stay and cover for you!" Tong Dali gritted his teeth and said.

"Wait a minute! Old boy, the 200 divisions are elite troops, and there is no need to sacrifice here. I have an idea, now the Ice General is seriously wounded, and the enemy from the other direction is biting us to the death. Therefore, it is difficult for the troops left behind to get out alive. More than 200 miles southwest of Caoyi Valley, there is a big mountain called Xiewang Mountain, which is a supply base for my Menglan Legion. Xiewang Mountain is not only a dangerous terrain, easy to defend and difficult to attack, but more importantly, there is also a reinforced regiment of ours stationed there, with a strength of about 3,000 troops. In addition, Xiewang Mountain is also equipped with twenty giant bed crossbows with wooden doors, and there are countless hidden passages. These conditions are enough for us to hold out for months until reinforcements arrive, without having to worry about logistical supplies. Mao Chong, commander of the Ninety-ninth Army, proposed.

"Leaning Mountain?, yes, I remembered. It was indeed a supply base for our army, and there was a reinforced regiment guarding it. After Tong Dali heard this, he suddenly felt a glimmer of life, and his mood improved slightly.

Xia Yan on the side also hurriedly said: "Two, we can't kill the Crescent River Valley at present." Moreover, even if we get out of Caoyi Valley, we are still in a huge encirclement of the enemy. On our west, north, and east sides, there is no way to heaven and no door to earth. In this case, Xiewang Mountain is our last retreat. Caoyi Valley is only more than seventy miles away from the Crescent River Valley, and those blood-red thunderbolts from Lord Bing General just now should attract the attention of the defenders of Flying Fish Pass. Therefore, we just need to stick to Xiewang Mountain and wait for help. In addition, we must immediately move in the direction of Xiewang Mountain. As I expected, Captain Scout, I am afraid that the 358th Division of your Seventh Army has all sacrificed their lives for the country at this time. What Commander Mao said just now is right, the two hundred divisions are the elite of my Menglan Legion. Since you want to stick to Xiewang Mountain for a long time, you must preserve your strength. So, I decided, leaving my guard battalion behind. ”

"I also agree with Commander Xia's suggestion, I will also keep my guard battalion, and in addition, add another regiment. Mao Chong also said categorically.

"Two, I, Tong Dali, am not a hypocritical person. Ask those who remain to go first and tell them that we, the brothers who have survived, will go underground to find them in the future. Tong Dali said with tears in his eyes.

Not much to say, the guard battalions of the 60th Army and the 99th Army, as well as a regiment of the 99th Army, were ordered to reinforce Yang Chongzhi, who was leading his troops in a fierce battle. Seeing that the old subordinates who had followed him for many years were gone, Mao Chong and Xia Yan's hearts were extremely heavy.

"Everyone listened, and after leaving the valley, they hurried towards Xiewang Mountain, and they did not stop for a moment. When they arrive at Xiewang Mountain, the army will rest and recuperate!"Tong Dali and Xia Mao, plus Sun Shimin carried Sun Yaoguang, who was covered in blood, and hurriedly withdrew from the dark Caoyi Valley.

In the early morning of May 1, Tong Dali's troops encountered the 20,000 Shangdang cavalry who had intercepted Qian Zheng before thirty miles north of Xiewang Mountain. The narrow road meets, and the two armies are staggered. At the critical moment, Mao Chong, the commander of the 99th Army, took the initiative to lead his troops to launch a counter-charge against the enemy, opening a gap for the 60th Army and 200 divisions, so that Tong Dali and Xia Yan led their respective troops to successfully withdraw into Xiewang Mountain. The remnants of the 99th Army fought fiercely with an enemy several times their size until noon, and finally they were unable to support themselves. Army Commander Mao Chong was wounded and captured, and the 99th Army was completely annihilated.

In the afternoon, this cavalry unit came to the foot of Xiewang Mountain and divided Mao Chong's five horses in front of the Northern Navy. Seeing this scene, Tong Dali was furious, and wanted to lead the army to fight to the death with the enemy under the mountain on the spot, but was finally held by Xia Yan and his subordinates. The arrogant Chengtian cavalry immediately launched an attack on Xiewang Mountain, but they were almost completely wiped out by the garrison guarding Xiewang Mountain with the twenty wooden door bed crossbows.

As for Yang Chongzhi, the ice soldier of the Seventh Army who stayed in Caoyi Valley and led his troops to break off, after fighting with the enemy until dawn, he finally died because the enemy was outnumbered, and none of them survived. After occupying the Caoyi Valley, the pro-forces of Chahe Buhua firmly controlled the valley and prevented the Beihai army from reinforcing in the direction of the Crescent River Valley.

On May 2, Subutai led his million-strong army to encounter the lone Cha and Buhua. After being hungry for two days, the marshal had a full meal and gobbled it up, and after hearing that the Beihai army in Caoyi Valley had withdrawn to Xiewang Mountain, he immediately led the Shangdang army to surround the three outer layers of Xiewang Mountain.

In the Battle of Caoyi Valley, although the Beihai Army on the periphery of the Crescent River Valley was not completely annihilated, it almost lost its combat capability. More importantly, Mao Chong, the commander of the 99th Army, was unfortunately killed, and Sun Yaoguang, a famous general in Beihai and the "Light of Thunder", was also seriously injured in this battle and died soon. In the battle in the outlying areas of the entire Crescent River Valley, a large number of outstanding generals of the Northern Navy were killed, and dozens of Bingshi were killed. The defeat in the Battle of Caoyi Valley marked the complete loss of the mobile force of the Menglan Legion for strategic counterattack, and the loss of all the three passes and eleven cities, making the defense line of the Crescent River Valley directly face the fierce attack of the Chengtian Empire.
