"Master, the eunuch who assisted Liu Xie at the beginning is likely to be called Yixin, does the master have his clues?" Guo Jia got drunk in Lu Rui's mansion, so he stayed in Lu Rui's mansion.

"Exactly, at the beginning, the division found a firewood shop that sent firewood to the palace according to the clues, and the building was empty, but some clues were also found."

"Clues?"

"Yes, according to the people next to him, this shop is after the completion of Xudu New Town, it is operated here, it is said that it was opened by a businessman in Hebei, surnamed Ma, and the owner is an old man, called Lao Ma."

"Old horse?"

"Yes, it is the old horse, according to the memories of some palace people, this old horse often goes to the palace to deliver firewood, and before sending people into the palace, the old horse has just finished sending firewood and left."

"It seems that this old horse is indeed very suspicious." Lu Rui ate a fruit and looked at Guo Jia.

"According to some intelligence and the characteristics of Lao Ma, Wei Shi and Ziyang preliminarily determined that Lao Ma is from Hebei, and according to the accent, he should be from Hanoi."

"Hanoi?" Lu Rui suddenly remembered a name, Hanoi Sima Yi!

"Well, Weishi also sent people to Hanoi to investigate, but after Guandu, Hanoi was captured by Yuan Shao again, and all the spies of our army retreated, and the matter was over."

"Yuan Shao recaptured Hanoi?" Lu Rui exclaimed, there is no such thing in history!

"Well, Yuan Shao sent his second son Yuan Xi to recapture Hanoi, and at the same time strengthened the Hanoi defense line, controlled Hedong, and then concentrated his forces to attack the Liyang area."

"Oh? Yuan Xi actually has this kind of ability? Lu Rui was stunned for a moment, Yuan Xi was a man, and he was in Liaodong at the beginning. The Gongsun clan is going to cut down the Yuan brothers. Yuan Shang's mischievous seed directly softened. Yuan Xi was still calm and went to die, but this spirit had the shadow of Yuan Shao.

"It's extraordinary, now I think that Yuan Shao's fourth son is not as good as the son of Lord Sikong, but I don't think so as a teacher."

"What does the master mean?"

"Yuan Shao's fourth son, Yuan Tan Wuyong, won the hearts of the army and was not under the eldest prince. Yuan Xi has both civil and military skills, the talent of the hero, and what is even more rare is that Yuan Xi is good at accepting words, if Yuan Xi inherits Yuan Shao's position, I am afraid that Hebei will be difficult to peace. The third son, Yuan Shang, although he is not good at writing, is good at power and strategy, and he is also half a character. The fourth son, Yuan Mai, is young, but he is talented and intelligent. I'm afraid that he will also be a plant boy in the future. ”

"Oh?" Lu Rui was stunned for a moment, he didn't expect Guo Jia's comment on Yuan Shao's fourth son to be like this. But it's right to think about it. In history, Cao Cao took two years to hit Yuan Shao's main force, but it took eight years to solve the problem in the north, and when the Northern Expedition was still Yuan Shang and Yuan Tan were fighting, Cao Cao's fishermen benefited, if the brothers worked together, I am afraid that Cao Cao could pacify the north in ten years.

"Extraordinary, don't underestimate the Yuan brothers, they are all experienced in battles, at least they are much stronger than the sons of the lord." Guo Jia glanced at Lu Rui earnestly, the Northern Expedition was not so easy.

"What the master said is reasonable, so Yixin is a person in Yuan Shao's army?"

"Well, when Yuan Shao was broken in Guandu that day, our army searched for a lot of communications between people in Xudu and Yuan Shao, and at the same time Yuan Shao collected information about our army, in the intelligence, we found Lao Ma, and he also provided Yuan Shao with information about Xudu."

"What does the master mean that the person who assisted Liu Xie that day was just an ordinary intelligence officer?" Lu Rui was stunned, the person who almost turned Xu Du upside down was actually just an intelligence officer?

"It's possible, but it's not sure, wasn't the teacher a pawn under Yuan Shao at the beginning?" Guo Jia smiled and took a sip of wine.

"Well, does the master have any suspicions?" Lu Rui nodded, there are many masters in Yuan Shao's army, but Yuan Shao doesn't use it, if Yuan Shao lets them all exert their talents, I'm afraid Cao Cao will not be Yuan Shao's opponent. This is also the difference between Cao Cao and Yuan Shao, the one who uses people well is the final winner!

"Locked some families in Hanoi and Hedong."

"The Wei family, the Sima family, the Fan family, and of course, the Hedong Taishou Wangyi!"

"So which one does the master think is the most suspicious?"

"Now that Hedong is no longer under the control of our army, if we want to investigate deeply, I am afraid it will take time."

"I see!" Lu Rui was not sure whether Lao Ma was from the Sima family at this time, could it be that Sima Yi was so bold, his brother was doing things under Cao Cao, and he dared to make a blatant move?

"Master Hou, Sikong Mansion sent someone to spread the word, and Lord Sikong wants to recruit Lord Hou and Lord Guo to go to the mansion to discuss matters." Lu Rui and Guo Jia were discussing a matter of one mind, and Cao Cao sent someone to recruit the two to go to Sikong Mansion, and the two of them had to tidy up their clothes and go to Sikong Mansion.

"Subordinates, see the lord!" Lu Rui and Guo Jia soon arrived at Cao Cao's mansion.

"Extraordinary and Fengxiao are here?" Cao Cao looked at the two and nodded.

"Did the lord invite the two of us here like this, did something big happen?"

"Yes, the original vanguard army has set off from Liyang, I have sent Wen Yuan to defeat the original vanguard, and now Ben Sikong has decided to lead 100,000 troops to conquer Liyang."

"The subordinates must assist the lord to defeat Yuan Shao!"

"Okay, extraordinary, you are still responsible for escorting the grain and grass, this time this time the company decided to take the initiative, the grain and grass must be sufficient, I will lead the troops to smash Yecheng and defeat Ben Chu in one fell swoop!"

"Yes, my lord!"

"Fengxiao, you are still a marching military division, and you will go out with this division."

"Yes, my lord!"

After seven days of preparation, Cao Cao led an army of 100,000 to the north to attack Yuan Shao in Liyang.

Outside the Liyang barracks of the Cao army, Zhang Liao greeted Cao Cao with civil and military forces.

"My subordinates have seen Lord Sikong!"

"Wen Yuan, please get up quickly." Cao Cao hurriedly dismounted and helped Zhang Liao up, and led Wenwu into the military tent.

"Wen Yuan, what is the situation of the two armies now?"

"Back to the lord, Yuan Shaoxing has 300,000 soldiers to retaliate against our army, and now on the left flank of our army is his eldest son Yuan Tan, leading 50,000 troops, and on the right flank is the second son Yuan Xi, leading 50,000 troops. Forming a flanking attack on our army, Yuan Shao led 200,000 troops in the center, approaching the front camp of our army! ”

"Three hundred thousand?" Cao Cao was stunned for a moment, Hebei is really a big land, and in just two years, Yuan Shao gathered another 300,000 troops.

"Ladies and gentlemen, Yuan Shao's 300,000 army is in front of our army, what are your strategies to break the enemy?"

"Back to the lord, Yuan Shao is powerful, our army has just arrived, and he needs to rest, his subordinates think that they should stick to the camp, wait for the opportunity, and attack to meet the enemy!" Xun You stood up and replied to Cao Cao.

"Okay, according to the plan of the Gongda, the whole army will be ordered, without my military order, no one can attack without authorization, and those who violate the order will be beheaded!"

"No!" The crowd bowed their hands and withdrew.

"Originally, we were going to war again, I really miss being young!" After everyone left, Cao Cao walked out of the military tent, looked at the military camp in the distance, and muttered to himself! (To be continued......)
