"This, of course, is the purpose of my trip. ”

Before waiting for Pu Zezhi's answer, there was a person who walked out of the hall, it was Xiao Yue.

Immediately after, Xiao Feng also walked out slowly, and when he saw the depressed faces of the two, he shook his head unconsciously and asked, "Did you fail?"

Seeing Xiao Feng ask about this, Zhang Che showed a look of shame, lowered his head and replied helplessly: "Yes." The Yunding Mountain is too hard, and its defense system mostly relies on the mountain, so even if we use artillery, it will be difficult to destroy those fortifications. If you want to break through Genting Mountain, I'm afraid you need to find another way. ”

"Looking for another way, do you mean cutting off food?" Xiao Feng pondered slightly.

At this moment, Pu Zhizhi opened his mouth and complained: "Although it is feasible to cut off food and water. But it takes a long time for this method to work. When I built Genting Mountain, I used to build a huge warehouse in it, which was specially used to store grain and grass collected by nearby farms. In addition, there is a cistern on the mountain, which can store the water that falls on weekdays and provide it for people to drink. If you really want to conquer this city, it will take ten years to do so. ”

"Ten years, so long?"

Zhang Che and Duan Feng were stunned for a while, and they were also quite surprised by this.

Pu Zezhi nodded and affirmed: "That's right, ten years." ”

"But you should also understand that we can't wait ten years. Xiao Feng opened his mouth to complain.

The main Mongolian force already knew the situation here, but because the army under its command was too large, it was really difficult to turn around in a short period of time, but if the other party turned around, the Red Phoenix Army could only let the other party reoccupy the entire Sichuan and Shu generation, just like the scene that had been staged in the Central Plains.

At that time, if Mongolia controls the Sichuan and Shu areas, the Red Phoenix Army may be attacked by the enemy and fall into many crises.

Xiao Feng categorically did not allow this kind of situation to appear.

Pu Zhizhi thought for a while, and after making up his mind, he said in a deep voice: "But if you go through a secret passage, you can step into Yunding Mountain. ”

"Secret way, I wonder if you can tell us?"

Zhang Che and Duan Feng suddenly felt their hearts flutter, and their two pairs of eyes stared at Pu Xuezhi, wanting to know what the secret path was.

If they knew about the secret passage, then they could break into the mountain city through this secret passage and completely control the entire mountain city in the hands of the Red Phoenix Army. What's more, the soldiers under the command of the Red Phoenix Army can also reduce their losses because of this, let alone lose so many soldiers.

Xiao Feng also bowed to Pu Zhizhi and asked, "If Mr. thinks it's okay, I don't know if you can help us break through this city?"

"Hmm. King Jin asked, how dare you disobey?" Pu Zhizhi closed his head slightly, and then replied slowly: "When I was building Genting Mountain, I was once in a state of delay because the construction materials were difficult to transport! Later, thanks to the help of Ran Jin and Ran Pu, Genting City was successfully completed. ”

"Oh, how did you solve it at that time?" Zhang Che hurriedly asked.

He once led a large army to attack Yunding Mountain, and naturally knew that this Yunding Mountain was steep and surrounded by cliffs, and it could be said that it would be extremely difficult to transport materials up.

It was precisely because of this that he was curious about what method Ran Jin and Ran Pu took to build this huge mountain city.

Xiao Yue and Xiao Feng were also staring, and Pu Xue wanted to know the trick.

Speaking of which, the two brothers Ran Jin and Ran Pu are really ingenious. They even came up with the idea of using the stone well to carry it. Pu Zezhi thought of what Genting City looked like when he built it, but it was rare to feel some nostalgia.

Zhang Che was puzzled and asked again: "Ishii, dare to ask the two of them, how did they transport the materials?"

Only then did Pu Zhizhi complain: "You should know that you are thirsty!"

"Of course I do. Everyone nodded in unison and replied.

Thirsty Wu was invented in the Eastern Han Dynasty, which can absorb water from low-lying areas and then irrigate it to high-lying farmland.

In this regard, everyone is naturally familiar with nothing

Pu Zhizhi immediately replied: "At the beginning, the two of them adopted this method to transport the materials needed for construction to the top of the mountain city. ”

"Oh, that's a really amazing way. Xiao Feng was also quite surprised, and asked again.

Pu Zezhi nodded and explained slowly: "At first, the two of them chose a suitable location on the top of the mountain, and then dug a shaft here. The shaft is about 20 zhang long, but it is a deep pool leading to the bottom of the mountain. This deep pool is three feet deep, and its strong water pressure is enough to press the water up the mountain. It is with the help of this shaft that we use the buoyancy of the water to transport the timber and stone used for construction to the top of the mountain. ”

When they finished speaking, everyone was already extremely surprised, and they were all shocked by this feat.

"So, if we can sneak into Shijing, we will be able to successfully conquer Genting Mountain?" Zhang Che thought of this, and his eyes suddenly lit up.

Pu Zhizhi shook his head, but there was a rare hint of anger: "Not necessarily." ”

"Why?" Xiao Feng asked.

Pu Zezhi smiled helplessly, his face was bitter: "I can't hide it." The fall of this city was caused by the Mongol army infiltrating the city from this secret passage. ”

"So that's the case?" Zhang Che was slightly disappointed.

Since the opponent has attacked Genting Mountain through this place, the opponent will definitely deploy heavy troops here to prevent anyone from taking the opportunity to break into the city.

Pu Zeyi looked annoyed and explained, "That's right. You must know that the secret passage here was originally only known to a few people, so in normal times, this Yunding Mountain has not been breached. But who knew that Yang Dayuan actually threw himself into the enemy army, and then leaked this secret to the other party. Otherwise, how can I incur failure?"

In his eyes, he seemed to return to the original scene of the destruction of Genting Mountain.

The corpses lying under the enemy's swords and axes, and the terrible sound of pain, made him wake up every night, and even now, he has never truly forgiven himself.

"That's true, but it's also a way to do it. Xiao Feng said to everyone: "And the other party's strength is limited. If we can divide our troops into three ways, then the other side will definitely be exhausted. And we also launched an attack at this time and captured Genting Mountain in one fell swoop. ”

"Three ways, don't you plan to take action yourself this time?" Xiao Yue was slightly surprised and asked.

Xiao Feng closed his head slightly and replied, "That's right." Three-way. One can continue the attack from the original mountain path in order to attract the enemy's attention, and the other can attack from Ishii to destroy the opponent's interior. And the last one, I will personally take the lead to lead the phosphorus out of Genting Mountain, so that it will be convenient for you to move when the time comes. You know, we've spent too much time here, and now is no longer the time to procrastinate. ”
