The Sinan carried by the Dingyan army is not as simple and accurate as the improved compass in Lanzhou, and as soon as the position is measured in the camp, the route of the army has actually shifted a little to the northeast, and the current road is not familiar to the guide sent by the tribe, and the guide is also embarrassed, after all, the grassland is as wide as the sea, deviating from the original road, even he can't determine whether he can accurately intercept the Lanzhou caravan, Cai Jifeng frowned and thought for a long time, although this time the raiding of the Lanzhou caravan was Cai Keyuan, Cai Kexian's two old dogs advocated it, but since he joined in, he returned in vain, and his reputation must be greatly affected. So Cai Jifeng ordered that without waiting for the dense fog to dissipate, the cavalry of each division was dragged back and forth with strips of cloth, slightly bent to the north, and accelerated its march to the north in any case, and in any case to block the way in front of the Lanzhou caravan.

As if the heavens heard Cai Jifeng's prayers, Xiao Jiu ordered the caravan not to advance when he encountered heavy fog, and the whole army set up the camp with partial vans one after another, more than 1,000 mules and horses were concentrated in the middle of the car formation, and the camp set up a fight, and in the dense fog, three hundred sergeants walked out of the car formation for 500 steps to establish a sentry post, and also urged the people to start digging trenches outside the car formation, setting up antlers and other obstacles. Xiao Jiu was cautious and resolute, thinking that the dense fog weather was likely to cause Wu Yingying's army to lose contact with his front, no matter what, it would be much easier for Wu Yingying's three thousand cavalry to find his own infantry army, so for now, the only way to do this is to slow down the pace of the march by himself in response to all changes with the same until the reconnaissance cavalry re-enters contact with Wu Yingying's department. He is cautious, and the camp must be set up with fights, antlers, trenches, etc., unlike Xin Gu, who only released scout horses, and the people who followed Xin Gu out of the fortress many times couldn't help but be a little resentful, and when it reached Xiao Jiu's ears, he just smiled.

Compared to Xiao Jiu, the dense fog caused greater difficulties to Xin Gu's department, and the more than a dozen cavalry detachments of the hussar battalion almost completely lost contact with each other, and now there were only one hundred and ten hussar battalion sergeants left by Xin Gu's side, he didn't know whether Cai Jifeng's army had left the Yin Valley Road, and he didn't know if the other cavalry detachments had encountered the enemy, but they had encountered a strong enemy.

When Amur led the seven tribal sergeants to explore the path in the thick fog, they suddenly heard the sound of horses' hooves in front of them, and almost at the same moment, the other side also spotted them, and both sides had no time to dodge, and almost a moment later, the bald and pigtailed Dangqiang cavalry appeared in front of them. The iron harriers led by Cai Jiqian almost collided directly with Xingu's hussar battalion detachment in the dense fog.

Cai Jiqian's subordinate Iron Harrier Ziye Alita saw that Xin Gu and the others were all dressed as Mobei herdsmen, but they were armed with bows, arrows, knives and guns, and they were obviously not easy people. The purpose of Cai Jiqian's trip is to fish in troubled waters, and he plans to attack the three uncles and brothers, so naturally he can't let outsiders see through his tracks, and carefully split others along the way. The first thing that Ye Li reacted to was the four words of murder and extermination, before he met, there were only eight people such as Amur, and he glanced at the iron harriers on the left and right, secretly took the scimitar into his hand, and kicked the horse's belly with both heels, and the river meandering horse rushed out like an arrow, and rushed into the other party's eight people in only two breaths, and the knife fell in his hand, and immediately cut down a shepherd from the horse.

Seeing their companions screaming and falling off their horses, Amur and the others were shocked and angry, and they were caught off guard for a while, all relying on their superb riding skills, cursing loudly in Mongolian, and dodging the lightning-fast scimitars of Yeli and others left and right. Most of the steppe tribes are good at archery, but except for warriors with outstanding martial arts such as Amur, their sword skills are mediocre. Yeli calculated this point, and without using a bow and arrow, he planned to kill these few shepherds who appeared out of nowhere with hand-to-hand combat. The party and the iron harriers are all tribal nobles who have practiced martial arts since childhood, and this sudden killer like a storm of sudden attacks, after a few breaths, the sergeants of the hussar battalion were cut down by three people, and the remaining four people did not even have the kung fu to draw their knives. If it weren't for the reluctance of Yeli and the others to hurt the healthy horses under their crotches, the swords and knives avoided the horses, but they were afraid that Amur and the others would have fallen off their horses and died.

Because of the thick fog, the distance between Xingu's hussar battalion detachment, Cai Jiqian's Iron Harrier brigade and their respective guards was very short, and both sides heard the screams and warnings of the hussar battalion sergeant when he was wounded and fell off his horse. Xin Gu frowned, regardless of the thick fog in front of him and couldn't see anything clearly, shouted loudly: "All guns, follow me!" In order to cover up their identity, the hussar battalion detachment spoke in Mongolian when they talked and ordered on the grassland, Xin Gu was a fiery character, and the sergeants of the hussar battalion were also very obedient to the order, all of them straightened forward with their spears, and with Xin Gu as the arrow, more than 100 people lined up in a sharp arrow formation, regardless of the thousands of troops and horses in front of them, or the cliffs, they rushed out at full speed.

Compared with Xin Gu's resolute determination, Cai Jiqian obviously had a trace of hesitation, and the left and right iron harriers took out their scimitars to protect them in front of him and asked him for his life, in this instant, Cai Jiqian frowned slightly, it was difficult to choose, the enemy in front of him was unknown, it was Cai Jifeng's people, Khitans, Lanzhou's people, or which one of them did not know the height of the sky and the height of the northern desert, and secretly complained in his heart that Yeli acted recklessly, and fought with the enemy in the fog, but there was no news back.

However, the military situation did not allow him to hesitate at all, and he heard the sound of horses' hooves on the opposite side quickly from far to near, becoming more and more neat and dense, Cai Jiqian, who was familiar with horse warfare, did not know that this was the enemy charging at full speed, and he wanted to crush his group in one fell swoop. Cai Jiqian didn't have time to think, pulled out his scimitar and shouted: "Kill forward!" Gently urging the horse, the iron harrier beside him couldn't hold it back, and they couldn't care about putting on the full set of iron armor placed on the reserve horse behind him, let go of the reins of the reserve horse, and rushed out at full speed.

In fact, Cai Jiqian and Xingu's main forces were only a hundred paces apart, and for the cavalry urging the horse at full speed, it was just a few breaths of time, first of all, Xingu's hussars met Yeli's men who were chasing and killing Amur and others.

Whether it is Yeli and other iron harrier avant-garde or Amur tribe warriors, hearing that the cavalry on both sides are charging towards this side at full speed, their faces show a frightened look, the cavalry head-on, like a hammer colliding with an anvil, everything in the middle will be smashed, Amur originally had some pestering Yeli and others, not to let them rush into the team's idea, but now he just wants to quickly urge the horse to the side to avoid the area where the two sides are fighting, he has no speed cavalry, under the full-speed impact of the cavalry formation, only to die.

Yeli no longer pursued Amur and the others, since there were a large number of enemy troops on the opposite side of the dense fog, it was pointless to kill these people, he adjusted the horse, put the scimitar on his chest and was waiting to accelerate the horse, suddenly a horse leaped out of the dense fog, and before he could see the other party's face clearly, a long riding spear passed through his chest, and the huge impact made Yeli's body fly backwards for several meters before falling to the ground. The Iron Harrier was originally wearing heavy armor to fight, but they suddenly met on the march, and the unarmored Iron Harrier faced the lightly armored hussar, and suffered a big loss as soon as he saw it.
