"Hurry, hurry up to Lao Tzu, you must not hand over these black-clothed cannons to the enemy!" On a certain high ground at the fishtail of Feiyu Mountain, a dignified, majestic middle-aged man loudly commanded his subordinates to carry black-clothed cannons, wearing the standard equipment of the Beihai Ice General-the silver-white star battle armor.

At the fifth watch, when Bai Hui's reconnaissance battalion commander Qin Sheng stumbled to the position of the artillery division on the cliff on the west side of the belly of Feiyu Guan, the commander of the artillery division, Guan Ying Nanbing, and his men were hurriedly preparing for the artillery bombardment. However, after learning that the army of the Chengtian Empire had entered Feiyu Pass, Guan Yingnan did not have time to be surprised, and immediately ordered the Divine Artillery Division to move in the direction of Tsim Sha Pass according to Bai Hui's order. At that time, about a hundred black-clad cannons had already completed their preparations for shelling. Therefore, Guan Yingnan designated ten of the cannons to be left behind, and simply ordered the more than 100 cannons to be divided into ten batches, and launched an artillery bombardment one by one like Zhu Chi's troops who were pouring into the pass.

And Karisha happened to lead the follow-up army of 50,000 to rush into the Flying Fish Pass at this time. I only heard a gust of wind whistling by, and ten huge black fireballs bombarded the Yukou position and passage in Feiyu Pass, instantly destroying the only passage. Of course, in addition to the roads, a large number of Chengtian soldiers were also bombarded to the ground. When Karisha looked up and saw that it was the haunting "black fire" that had lingered a few days ago, she was immediately frightened into a cold sweat, and hurriedly ordered one of his subordinates to rush towards the hinterland of the Flying Fish Pass with the soldiers who had already rushed into the mouth of the fish. He hurriedly led the rear army to escape outside the Flying Fish Pass. Karisha knew very well in her heart that the shelling of the Northern Navy at this time was obviously to prevent her from reinforcing Prince Zhu Chi. However, due to the shelling a few days ago, the soldiers of Chengtian have developed an infinite fear of these large black fireballs, and if they do not avoid the edge for a while, they are afraid that they will mutiny.

Therefore, only about three thousand or so soldiers rushed to their Mu King's side after Zhu Chi broke through the pass. It wasn't until more than an hour after the artillery division's bombardment ended that Karisha dared to lead a large force to "walk" into the Flying Fish Pass with difficulty. At this time, the mouth of Feiyu Pass was already unrecognizable, and it was extremely difficult to walk.

Because of the re-firing of the artillery division, Zhu Chi did not eliminate the remnants of the Beihai army in the Fish Belly Valley until noon, and killed the veteran Bai Hui with his own hands.

On several high ground at the tail of Feiyu Mountain, more than 10,000 soldiers of the Eleventh, Thirty-third and Thirty-seventh Armies withdrew, under the leadership of their respective commanders, held their positions and struggled to cover the retreat of the artillery division to Tsim Sha Pass.

In the afternoon, Qin Sheng rode alone to the bottom of Tsim Sha Pass, and reported the news of the loss of Feiyu Pass and Bai Hui's death in battle to the general of Tsim Sha Pass, the commander of the New Fifth Army, Peng Dingfang. Frightened, Peng Dingfang and Qin Sheng hurriedly took the New Fifth Army and the New Fifty-eighth Army and a large number of mules, horses and vehicles out of the pass to the west, and two hours later met Guan Yingnan and his subordinates, who were exhausted from dragging hundreds of black-clothed cannons. Subsequently, Peng Dingfang and the New Fifth Army continued to rush to Feiyuguan, originally wanting to pick up the troops left behind the broken Yuwei Heights. Unexpectedly, as soon as the New Fifth Army saw Feiyu Mountain, they saw countless Chengtian cavalry brandishing the full moon scimitar and rushing towards them.

Seeing this scene, Peng Dingfang knew that the troops at Feiyu Pass were truly finished. If he rashly reversed at this moment, maybe his troops would be defeated. With no way to retreat, Peng Dingfang stubbornly led the New Fifth Army to launch a counter-charge against the cavalry of the Shangdang Legion, determined to desperately drag the group of wild horses in front of him. In the face of an unfavorable battle situation, what kind of countermeasures will the leader of the Menglan Legion, Shiraishi, make?
