After Hao Jian carefully asked the flat head case a few more times, he was much less worried about Ran Wu and the three of them.

According to Bian Braincase, Ran Wu and the three of them hid in the back village where the bandits lived and settled their families on weekdays, and there were no people in the back village to protect them, they were all women and children, these warblers and Yanyan basically had no combat effectiveness, and most of them should be the folk girls who were robbed by the horse thieves, so they should not pose any threat to Ran Wu.

According to the flat braincase, the back village is the most easy to defend and difficult to attack inside the whole cottage, built by the mountain, the gate is made of large pieces of bluestone, the wall is three feet high, if it is not opened from the inside, it is very difficult to attack from the outside.

In addition, except for the mountain on the back, there is open land on three sides, so it is basically difficult to find a high ground from the outside to shoot from a high position.

The mountain behind it is even more impossible, according to the flat braincase, the mountain behind it, not to mention people, even monkeys can't climb it, it is a smooth mirror-like stone wall, which is basically difficult to climb.

In this way, with the ability of Ran Wu and the others, they should be worry-free for a while.

However, it is necessary to arrive as soon as possible to respond, otherwise they will sooner or later be attacked by the horse thieves, these horse thieves may be jealous for a while because of the family inside, but many of the people who do this are ruthless, so after losing patience, they may give up the lives of these women inside.

Let people leave the flat head case and get him some food and drink to appease him, this kid will also come in handy.

Back on the road, Hao Jian ordered to speed up the march, and the speed of the whole team suddenly increased.

Fortunately, tonight is the night of the full moon, and a full moon above the sky will illuminate the earth clearly.

Hurrying slowly, I finally arrived in front of the gourd valley in the second half of the night.

Looking at the gourd valley under the moonlight, Hao Jian couldn't help but admire: "What an excellent base." ”

I saw that where I looked up, two large mountains stretched from the northwest to the place in front of me, and the two mountains were towering from a distance in the moonlight, and there were countless mountains of all sizes on them.

At this point, the height of the two mountains has been much lower, and the original parallel trend has been changed, and they are relatively intertwined. It's as if a person is holding a large ball between his two arms stretched forward.

The place where the two hands meet is naturally the valley mouth, and the big round ball that does not exist is naturally the valley belly.

The mouth of the valley looks very down from afar, and the narrowest point looks less than three feet away.

And in that place, it happens to be a walled wall as high as four or five zhang, and from a distance, there are several commanding heights such as arrow towers and sentry towers on both sides.

"This place is really a good place, it's absolutely easy to defend and difficult to attack, this place is going to be decided!" Hao Jian looked at it for a long time and smacked his lips.

He'd fallen in love with the place and was determined to get his hands on it.

With such a place, in this era of cold weapons, it is not easy to use more soldiers.

"This place is indeed a good place, but, my lord, from the bottom of it, these bandits are a bit of a tyrannical thing." Liu Ji touched his beard and shook his head.

"What's the explanation?" Hao Jian asked.

"You see, my lord, although these horse thieves know that they have built a wall at the exit of the valley, beyond this wall is a plain wasteland. If an enemy is attacking, the army can be deployed here.

And if there are heavy siege weapons, the wall can be broken after repeated attacks. However, if a higher wall is built further into the valley, if the enemy breaks through the first wall, then the defenders can retreat to the second wall to continue the defense, which has the advantage of inflicting a lot of casualties on the invading enemy.

Second, even if the enemy breaks through the first wall, it will not be able to invest more troops because of the narrow terrain at the mouth of the valley, and even if the troops are invested, they will be crowded and dense because of the narrow terrain, and if the defenders can attack with fire on the second wall, the enemy will definitely encounter a nightmare.

Third, if some caves are dug in the stone walls on both sides of the valley mouth, if the enemy comes to attack, then the enemy can also attack the enemy from both sides, so that the enemy army is unable to defend itself.

Of course, there are still many defensive strategies, and they haven't been completely thought of at the next moment, so they say that these bandits are tyrannical creatures. “

Liu Ji touched his beard and talked eloquently, shaking his head from time to time as he spoke, as if he was very disappointed with the uncompetitive performance of these horse thieves.

Hao Jian took a closer look, thought about it, and found that the old fritters' eyes were still very sharp, and he couldn't help but glance at him again.

However, the words of this old fritter sounded a little wrong, Hao Jian patted Liu Ji on the shoulder and said, "Strategist, dare you feel sorry for the bandits?" ”

Liu Ji was happy, didn't hear the meaning of Hao Jian's words, and continued to shake his head and said: "Yes, if you let it run down, it will definitely make this valley a real copper wall, solid as gold, if someone really comes to fight, it will definitely make their heads bleed and lose confidence." ”

Hao Jian looked at the old fritter and shook his head with an intoxicated look, and said angrily: "Fortunately, these bandits are blind and didn't let you be a military advisor, otherwise Lord Ben would have bled on the head here and doubted his life." ”

Only then did Liu Ji react, and hurriedly smiled awkwardly and fled away under the pretext of urgency.

However, Hao Jian really agreed with Liu Ji's words, and made up his mind to let Liu Ji rebuild the fortifications at the mouth of this valley according to his idea when he took Hulu Valley, so that everyone who dared to fight the idea here would have to break their heads and doubt their lives.

Just like when he used to play fortress games, he always liked to enclose the entire territory with three layers of walls, and then erect tall towers on each side, each of which was not only garrisoned by archers, but also ballistae or small trebuchets.

There was also a moat dug outside the walls, so that even if the enemy attacked, they would have to be confined to the city gates.

And there will be a large number of traps in front of the city gate, and even various defensive measures such as war dog cages, even if the enemy breaks through these lines of defense and attacks under the city gate, he will already suffer heavy losses.

With the urine nature of computer AI, it is impossible to invest too many troops to attack at one time.

So every time he relies on this kind of hooliganism, Hao Jian wins steadily.

So in the future, after unlocking all the system functions, these things can be used on the layout of the gourd valley according to the cats and tigers, and the effect will definitely be the same.

"My lord, it's not early, let's rest." A light cavalry who had been temporarily transferred by Hao Jian to serve as a herald came over and said.

"Okay, all rest, prepare for war after dawn, and we will definitely take the gourd valley in one fell swoop!" Hao Jian looked at the gourd valley like a sleeping dragon in the moonlight and muttered.
