Listening to Shen Feng's question, Cen Seng's eyes also became deep, looked at the tight army array opposite the military prison, and said: "Why is the millennium so immobile, there must be something else."

Then he asked, “What is the picture of each other?”

Cen Sen said, “This kind of deployment, but not sending a soldier to come, must be secretly planning something.”We still do not know how they are prepared before the attack, and we do not know how they are going to attack them."

Hearing this, Shen Feng suddenly thought of the three volumes of soldiers that Wang Zhongyi had taught himself before his death.

Wang Zhongzi was framed by Li Linfu, after being deposed as Hanyang, it was also a leisurely, and there were not many jobs every day, for Wang Zhongxi, a general who led the battle of the army all the year round, there was no soldier under his command, and the days were also depressed.

And Wang Zhongzi is not empty years, so he used this time to write down the experience of his soldiers for decades, the essence of the military method, and compiled into three volumes of the military book.

These three volumes of the method of arms, the three volumes of heaven, earth, and man, correspond to the time of heaven, the land, and man.The leading war is nothing but these three: the heavens, the angels, the geography and the terrain, and the people who rule the way of the army and the unexpected.This is what Wang Zhongxi has learned from countless battlefields, and it is also his life's work.

Before his death, Wang Zhongxi did not even teach these three books to his own son, but gave them to Shen Feng.

What kind of person Wang Zhongzi is, he has long seen that Anlu Mountain has long been rebellious, and has always been accumulating strength for himself, only when the time comes, will certainly raise troops to rebel against the Tang.

And when Anlu Mountain started to fight, he could turn the tide and restrain Anlu Mountain, and it seemed to be only Shen Feng in the eyes of Wang Zhongyi, so he passed on the three volumes of the army books he had earned in his life.

After Shen Feng got the three books of Wang Zhongzi, he naturally studied it carefully, and also firmly recorded the essence of the military method in his heart.

Looking at the situation in front of him, Shen Feng murmured in his mouth: "But the law of taking the city is nothing but siege, strong attack, and wisdom."And the wise, unexpected, also for the night attack, the water, the fire, the four ways of the cave attack."

Hearing Shen Feng say this, Cen Sen hurriedly asked, “Lord, I don’t know what you said, from that soldier’s book?”

He was also familiar with the book, but Shen Feng just said that, but he could not remember the source.

Shen Feng sighed and said, “This is the book of the soldiers that Wang Zhongyi was written before his great life, and the earth volume is also one of them.”

“Adult Wang Zhongyi...”

Hearing Shen Feng mention the name, Cen ginseng's heart is also a heavy and regretful.The generation of Tang's military gods, the four towns, actually was dismissed by Li Longji, died in Hanyang's duty, how not to regret it!

Cen also did not know that Wang Zhongzi did not die of illness, but was secretly sent to poison and die by Anlu Mountain, and there were still books of soldiers before his death, and he passed it to Shen Feng here.

Shen Feng turned his head and looked at Cen Sen and asked, “The unexpected seizure of the four laws of the city, to see what kind of millennium will choose.”

Tsingseng thought a little, immediately replied: "The night attack that trick, Cai Xiede under the thousand years has tried, failed and returned, it is estimated that it will not be used again; this move of water, for the martial arts can not be exerted; fire attack, we are strict, before those stone-throwing car shot out of the fire but for us, but also can resist the fire, they may use; and this last one is the cave attack."

Of these four methods, the cave attack is the most hidden and the most unexpected.Cen joined the army, in your opinion, the other side before this military prison before the army came, but the army is not standing, do you want to cover what?"He looked at the chorus and asked.

Cen ginseng face heavy, slightly nodded said: "Lord Shen means that they may take the method of pitting attack, and the army in the arms before the military gate, is to cover their actions to dig the way?"

“Extraordinary this is possible!They appeared so many soldiers and horses, but they did not move, it was really strange, and they were so lined up, they were united in truth, and we could not see what kind of name we were making at a glance.Maybe they're just choosing somewhere, they're digging in the tunnel in the dark."

Shen Feng immediately looked at Cen Sen and asked, “If the other party digs into the tunnel, what kind of detection method can we have in this military prison?”

Tsing was originally a soldier in this military prison, very familiar with the situation of the military inside, and immediately replied: "Lord Shen, buried at the foot of the wall within the Wuguan, half into the ground, the bottom is empty, if there is an enemy from the city outside the excavation tunnel, in the excavation of the tunnel to about half of the city, from this urn can be seen to hear the movement!"

Listening to this, Shen Feng nodded his head, which is no different from the historical books.

"But when the urn under this city can detect the movement, the tunnel dug by the enemy is already half a step away from the wall of this military prison, and just through these dozens of urns, I am afraid that it is impossible to know the exact location of these authentic roads, if the other side continues to dig, what restraint do we have?"He looked at him and asked.

Censen replied: "The best way to defend against the enemy digging the tunnel is to build a moat outside this wall."However, the land outside this prison is sandy, and it cannot hold any water at all, so it is impossible to dig a moat outside the gate.In order to defend against the enemy's secret excavation tunnels, only a few large reservoirs can be set up underground in the Wuguan urn city, and the bottom is paved with slates to store water.No matter how the tunnel is excavated, no matter what the location and direction, it will eventually be dug into the urn city, and it is very likely that these cisterns will be encountered when the excavation is carried out upwards. Once the bottom of the reservoir is destroyed, the water in the pool will be poured into the tunnel, thereby destroying the tunnel.”

Shen Feng thought for a moment, and then looked at the Censen said: "In this urn city in the underground reservoir, this is a good way."But if the other party is proficient in the art of the cave, the exit of the tunnel avoids these cisterns, and our defense is still dangerous.Defense is always passive, we have to know the enemy's movements and intentions in advance, if the other side digs the tunnels, it must be destroyed early, can not let them close to the wall of this military prison!"
