Li Haochen left the Xuanwumen garrison barracks of the right Yiwei, and returned to the barracks of the camp with a box of gold bars knocked out of bamboo poles, and after arriving at the barracks, Li Haochen put down the gold bars and hurriedly instructed the soldiers to prepare pen and ink, and at the same time prepare two pieces of white silk that are square and one zhang square.

After the soldiers prepared these things, Li Haochen ordered the soldiers to wait outside the big tent, no one was seen, everything was ready, Li Haochen began to sketch and draw inside the big tent, about three or four hours later, Li Haochen drew two patterns on the two white satin sheets prepared.

If the Xuanwu Gate guard is always here at this moment, it is estimated that his eyes will fall, because what Li Haochen drew is the "Xuanwu Gate Defense Map" and the "Xuanwu Gate Location Map", and these two maps are not bad at all.

Li Haochen looked at his masterpiece and nodded with satisfaction, why did Li Haochen remember these 256 marker points with just a glance at these two maps, how did he do it?

This is the secret in Li Haochen's heart, and he is afraid that he will not tell anyone in this life.

Things have to start from when he was assassinated by that authoritative professor in his last life, Li Haochen was unwilling in his heart, he vaguely had a voice, when he opened his eyes again, he was already in the Tang Dynasty, and in a few days of life, he found that he had an extra magical skill, that is, he could never forget. Remembering and learning things very quickly, which is why he was able to master the "Peerless Halberd Method" and "The Art of War" so quickly.

When Li Haochen obtained this skill, he not only thought of some of the online novels he had read in his previous life, in which the protagonists all crossed by accident, and then obtained extraordinary abilities, commonly known as golden fingers, these golden fingers, some can summon generals, some can dominate the world, some can catch whoever they want, some can become immortals, and so on, are very powerful, think about him, this is also considered a crossing, if what the novel says is true, then is his golden finger too weak? At that time, Li Haochen really didn't know what he could do with such an ability, and he was very aggrieved in his heart.

Li Haochen really wanted to scold the sky at the beginning, because he always felt that God bullied him, a fat man with bad luck.

But in the next few days, he was relieved, first of all, he comforted himself, although this ability is not strong, but it is better than nothing, and then he didn't expect that he first used this ability to learn Lu Bu's "Peerless Halberd Method" and Gao Shun's "Art of War", and today he also used this ability to Yin Changhe, which made Li Haochen sigh that the traverser is really good, this golden finger is actually quite easy to use! As the saying goes, if the heart is wide, the body is fat, no wonder he is a fat man of 300 pounds, this mentality is really good, and it can't be better.

Poor Chang He never dreamed that Li Haochen was actually a time-traveler with a golden finger.

After Li Haochen looked at the ink on the two maps, he carefully studied the two maps, and Li Haochen found that in fact, there are eight corner gates between the Xuanwu Gate and the palace gate, which are the east gate, the west gate, the south gate, the north gate, the southeast gate, the southwest gate, the northeast gate, and the northwest gate.

Li Haochen clearly remembers that there is a wild history that is clearly recorded in:

On the fourth day of the sixth month of the ninth year of Wude, the king of Qin colluded with the Xuanwu Gate guard Chang He in the south corner gate, and the north corner gate set up an ambush, when the prince and the king of Qi entered the Xuanwu gate, they closed the gate of the Xuanwu Gate, cut off the guards of the prince and the king of Qi, and after the Xuanwu gate was closed, the ambush soldiers were killed......

Li Haochen secretly said in his heart, if Li Shimin really only set up ambushes at the north and south corner gates, then the rest of the corner gate positions can be ambushed, the key is that now there is an opportunity to ambush the troops openly.

At this moment, he was thinking about how to trap his 5,000 people in the camp and hide Chang He from entering the Xuanwu Gate to set up an ambush. But if Li Shimin saw Chang He being captured, then he would definitely throw himself into a rat trap and dare not launch a coup d'état, so when he captured Chang He privately, how to explain it to the prince and the emperor is a problem.

Li Haochen was also entangled at the moment, there was no particularly good way, he decided to discuss countermeasures with Wei Zheng, so he sent someone to Wei Zheng's mansion to invite Wei Zheng to come to discuss, originally he wanted to go to Wei Zheng's mansion in person, but I am afraid that at this moment, Wei Zheng's mansion has been closely monitored by the people of King Qin, and his military camp is a relatively safe place.

About half an hour later, Wei Zheng came in a hurry, and after seeing Li Haochen, he said: "Haochen, I told the prince that you want to remove the guards of the Xuanwu Gate, but the prince disagreed, and the prince said, Chang He has contributed to the Tang Dynasty, and it is not appropriate to remove him without making a mistake." And if the crown prince does this, His Majesty the emperor will definitely not agree, after all, Chang He is defending the Xuanwu Gate, if the prince changes people privately, the emperor will definitely be suspicious! ”

Li Haochen nodded when he heard this: "Brother Wei and the crown prince are right, I was reckless!" Brother Wei, I called you over because I wanted to ambush the five thousand trapping camp in this Xuanwu Gate on the morning of the fourth day of the sixth month to ensure the safety of the prince, but if I can hide it from Chang He's eyes? ”

Wei Zheng said with some doubts on his face when he heard this: "Haochen, why are you sure that Chang He will definitely be unfavorable to the prince?" Wei Zheng was often suspicious of Li Haochen's blind suspicion.

Thanks to Li Haochen's quick reaction, he hurriedly said: "Brother Wei, I'm not sure that Chang He will betray the prince, but the fewer people who know about this matter, the better!" You know that the prince cares too much about sibling affection, and he has tolerated the king of Qin many times, I think it would be best if the king of Qin didn't do it, he left the capital in the future and there was no threat to the prince, if he did, I must arrest him, and let the prince see the true face of the king of Qin. And if King Qin makes a move, I have analyzed it before, Xuanwumen is the best choice, if this is the case, King Qin will definitely buy Chang He, so Chang He has to be guarded against!

Taking a step back, even if King Qin didn't pass the Xuanwu Gate of Chang He Ambush, the fewer people who had to know, the better, if there were more people who knew, I was afraid that he would startle the snake and fall short in the end! ”

Wei Zheng listened to Li Haochen's analysis and nodded, Wei Zheng had to admit that Li Haochen had considered this matter very comprehensively, pondered for a while, Wei Zheng said: "What you said makes sense, so be it!" You 5,000 soldiers, I'll help you transport them to the Xuanwu Gate tomorrow! The rest is up to you! Wei Zheng also had no bottom in his heart, thinking about being careful to sail the 10,000-year-old ship, Wei Zheng still chose to help Li Haochen.

Li Haochen was secretly happy when he heard that Wei Zheng had a way, but he had some doubts in his heart, so he said to Wei Zheng: "Brother Wei has any way?" ”

Wei Zheng smiled and said nothing, his cousin was mysterious, but Li Haochen was very puzzled, Wei Zheng repeatedly assured Li Haochen that there would be no problem, so he got up and said goodbye, Li Haochen knew that everyone had their own secrets, so he didn't ask Wei Zheng to the bottom of it, but sent Wei Zheng out of the camp, and then reflexively returned to the big tent.
