"What else is the enemy moving in recent days?" I asked.

"The end will be high and far away. It was found that the enemy seemed to be slowly retreating for the past three days. Yang Yi pondered for a moment and looked up to reply.

"How far was the confrontation between the two armies before?" I frowned and asked, the army of Northern Qi should not retreat, there must be deception in this.

"Two hundred and eighty miles. Yang Yi replied.

I nodded silently and did not speak, the qi observation technique can see that the enemy army is four hundred miles away, that is to say, the enemy has retreated more than a hundred miles in the past three days, the heavy troops have chariots and war horses, and the armor will only be worn when they go into battle, if they march quickly, the heavy troops can move eighty to one hundred miles a day, and they retreat more than a hundred miles in three days, and the average retreat speed of forty miles a day is not fast.

"General Yang, what do you think of this?" I turned my head to look at Yang Yi, he is the main general here, I can listen to his opinion first.

"There was a great deal of trouble with the round iron tool, and the last general had sent people to dig it up, but he heard only the roar of thunder, and no soldiers returned. The last general thought that the iron weapon used by the enemy was a sharp weapon for killing, and with this sharp weapon, there was naturally no need to defend the border state with soldiers, and it was logical for the enemy army to retreat. Yang Yi thought for a long time and said.

General Yang has a point. I nodded. Yang Yi's analysis is very correct, so I want to praise him. But I'm not as simple as he thought, Ye Aofeng can arrange mines in a large area, indicating that these mines were built by him before, since they were built before, why didn't he bury them before the golden dragon was born, but waited until after the war to bury them, there must be a reason, or something strange.

"I will go to the territory of Northern Qi to check the enemy's situation, and General Yang will prepare the following pen and ink for me. I got up and walked out of the camp.

Yang Yi then prepared pen and ink for me, Xu Shuangyi and I drove Peng to the east again, at this time the sky was already dark, and there were no stars and moons, the flight altitude of the golden-winged Dapeng was not high, I pinched the qi trick and looked down at the enemy.

The circular iron tool that Yang Yi observed earlier was indeed a mine, but the arrangement of the mines was quite sparse, and it would take hundreds of steps to lay the next one, which showed that the number of mines created by Ye Aofeng was not much, and the deterrent effect would be greater than the actual killing effect. Ye Aofeng is very good at figuring out people's psychology, the number of mines he lays is very limited, but it is this limited mine that will cause huge psychological pressure on the soldiers of the Northern Zhou Dynasty, first, they don't know this modern weapon, and they have an inexplicable fear of it. Second, because they don't know if they will step on a landmine, they will tremble and cower.

If someone else's analysis stops here, no one will continue to think deeply, but I am the kind of person who must know the truth, I feel that things may not be so simple, Ye Aofeng uses mines instead of soldiers to defend the border It seems that it is too much in line with the public's thinking mode, he Ye Aofeng is not an ordinary person. In addition, there is another reason why I am suspicious, that is, the army of the Northern Qi Dynasty only retreated forty miles a day, according to such a sparse mine arrangement, he should not only retreat forty miles a day, he can completely retreat at full speed while laying mines, in other words, the placement of mines is not enough to delay his retreat, in this case, why should he deliberately delay the speed of retreat?

The flight speed of the Golden-winged Dapeng was extremely fast, and soon we flew to the sky above the Northern Qi army, and the Northern Qi army was also mixed with people from the Daomen, in order to prevent them from being discovered, Xu Shuangyi ordered the Golden-winged Dapeng to increase the flight altitude.

The formation of the Northern Qi army is not the same as the three lines of defense arranged by our Northern Zhou Dynasty, they use a five-point arrangement, and the long front is arranged with five legions, one, three, five in the front, two or four in the rear, the whole formation is like an M shape, where we are now in the middle of the battle line, hundreds of miles away in the north is a densely populated place in the Daomen, depending on the situation should be the command post of the enemy.

"Look north. I said to Xu Shuangyi.

The latter nodded in agreement, and instead gave the order to turn to the Golden-winged Roc. At this time, in the dead of night, there was only the sound of the wind stirred up by the golden-winged Dapeng flapping its wings, looking at Xu Shuangyi, who calmly drove the mount, I couldn't help but think of the scene when the two first met twenty years ago, although I have been feeling that time has passed very slowly in the past twenty years, but now looking back, I feel that time has passed very quickly, and in a blink of an eye, the arrogant and cold beauty matriarch has become a middle-aged woman who is not confused, looking at Xu Shuangyi, who has given birth to white hair in front of me, my heart is extremely sour.

"Are you hungry?" I asked. The quiet night always softens the heart, and Xu Shuangyi has not eaten since the early morning departure.

"It's fine. Xu Shuangyi shook his head slightly.

Xu Shuangyi stopped talking after speaking, and I couldn't find a new topic for a while, so I could only sigh secretly and stop talking. The Golden-winged Roc flies fast and at high altitudes, and the cold of the night makes Xu Shuangyi shiver, she has lived in the warm south all her life, and the cold of the north makes her very uncomfortable.

Seeing this, I hurriedly extended the aura and set up an aura barrier in front of her to block the cold qi, she only practiced half of the qi practice method in the book of heaven, although the spell was mysterious and the arrows were superb, but the physique could not be compared with the real sense of the cultivator.

The sudden disappearance of the cold made Xu Shuangyi slightly puzzled, and turned around to look back, I smiled at her and didn't explain much. Who knew that Xu Shuangyi's eyes instantly turned red after seeing my smile.

"What's wrong?" I asked, confused.

"Why don't you protect your body with aura?" Xu Shuangyi's eyes were tearful, the biggest damage to a woman's appearance was the wind and rain rather than the years, although Xu Shuangyi had white hair and a little frowning, she was still beautiful.

"I'm not cold. I shook my head. Before, I just extended the aura to wrap herself, and I myself did not protect my body with the aura, the reason why I did this is because the aura is too precious, and it can save a little bit, in fact, although I can't feel the cold, the feeling of the cold wind still makes me frown and squint, and the immortals who disperse the aura are no different from mortals.

"Your aura is precious, and it will be of great use in the future, don't spend it for me, take it. Xu Shuangyi's expression was extremely moved.

At first, I was very puzzled by this, I didn't understand why she was moved to tears by this little thing that seemed trivial to me, but after a deep groan, I understood the reason why Xu Shuangyi was moved, I cherished the aura and was not willing to arrange a barrier for myself but set up a barrier for her alone, this unconscious move made her see my heart. In fact, I really didn't do it deliberately, I just didn't want to bother myself with my own anger, it was a completely unconscious move, and it was because I was an unconscious move that Xu Shuangyi was moved to tears, because she knew that unconscious actions were often the true thoughts of people's hearts.

"Do you regret it?" I sighed after a long time, and I always felt inexplicably sorry in my heart for her twenty years of empty waiting, this woman's life was ruined at my hands.

"If there is an afterlife, I will still draw my bow to find you......"
