Cao Cao came to Guo Ming for lunch today to discuss the matter of "striking first".

The three of them sat on top of the restaurant, looking at the scenery outside the window. All the people around me sat down and ate their meals.

There is a screen outside, and there are only three of them in this room.

Cao Cao spoke directly: "Regarding the matter of Xiapi, I want to listen to Fengde's meaning first, and then discuss it with the generals." ”

"Brother Xian, my lord, this is putting you and me above all the counselors. Virtuous brother, don't Meng Lang. ”

The meaning of Guo Jia's reminder next to him is very simple, that is, to tell Guo Ming that Cao Cao is playing for real, but don't fake things.

Guo Ming could only smile, and directly picked up the water scoop next to him and sprinkled it lightly on the table.

Then he turned the small bowl he had used for drinking upside down and placed it on the water.

"Ming Gong, the victory is in hand, so why bother asking?" Guo Ming put his hands in his sleeves and said.

Cao Cao frowned and looked at this scene, thinking thoughtfully.

He lightly nodded Guo Ming's wine cup: "Is this Xiapi?" ”

"Exactly."

"But it's not the rainy season." Cao Cao said.

Of course, Guo Ming knew what he meant.

When Cao Cao attacked Pi in history, he actually fought for a whole winter, and only in the beginning of spring did he take advantage of the thaw of the flood to flood Pi and succeed in the first battle.

That's what Guo Ming is saying.

However, he couldn't make it clear.

Otherwise, Cao Cao's cautious eyes must not think that he will ridicule him for not knowing how to use soldiers.

"The minister only heard some things from ancient books, and it is said that Xiapi Castle did not think of the trouble of Surabaya when it was built in the first place. On weekdays, there is a slight rain, a wind and something like that, and the city is shivering. If someone raises the downstream river, it will be blocked by half of the river......"

When talking to smart people, you must remember to leave a lingering rhyme, and you can't finish everything at once.

Cao Cao understood it completely this time.

"I see."

Guo Jia hurried, straightened up and said.

"Ming Gong, Feng De can't compare to those gentlemen who only know how to read dead books. In fact, this plan can be used in parallel with the Ming Gong's soldiers, and it is not contradictory. ”

Cao Cao felt the same way.

"This plan can be attacked, retreated can be defended, if you take advantage of the midwinter when Surabaya is low, you can just block it. When the spring floods the following year, the Surabaya riverbed can be lifted from there. ”

"If our army breaks through Xiapi within three months, we don't need to do this, and if we can't take Xiapi within three months, then Dashui can still take Xiapi."

"So as long as you act according to this plan, Xuzhou will be stable just around the corner, and you can calculate it by pinching your fingers."

Guo Jia slapped this sycophant, and Cao Cao laughed.

He stroked his beard slightly, satisfied.

"With this strategy, you can know that my Weiyin Pavilion Marquis is not sealed in vain. Fengde, you can go to one of the upper and lower ends, such a good plan can't let you have no performance in the merit book. ”

"I knew it was going to be mine, okay, I'll go downstream."

The lower reaches of Surabaya are just in the northeast of Xiapi City, and Liu Bei is far away, and they can't see each other at all.

What Guo Ming is most afraid of now is Liu Bei and Cao Cao, the two big demon kings.

He now has a principle, far from fighting the Great Demon King.

Liu Bei is a good person, but unfortunately there is nothing to repay.

Cao Cao's suspicion is too heavy, so it's better to stay away.

Just go downstream and think of a way, just raise the whole downstream.

Of course, Guo Ming has seen in books how this method is blocked.

There are about six or seven dikes in front and back, and the first dikes can be almost a quarter higher than the downstream riverbed.

Then each layer is about a quarter higher than the one behind it.

In fact, the entire terrain has been turned into a reservoir, and the water storage in March must have a bit of flow.

Guo Ming can just use this opportunity to create things that he has always wanted to create.

Cement!

This thing is so easy to use, both in construction and in military terms.

Guo Ming has now figured out his own strategy, which is to measure the size first, and then use cement to make a component.

Fill in the structure into the river, and then seal the gaps on both sides with cement, and you're basically alive.

Not particularly difficult.

He was just able to publicize the role of his cement, and if he could build Xudu's real estate or Luoyang's real estate in the future, it would be a lot of money.

Best, Cao Cao can let him build the Tongque Tower.

Don't break the law, don't have an accident, but these are all after the crusade against Yuan Shao.

Now, it's too far from that.

"Fengde, I don't plan to let you stay in Xuzhou City for too long, if it's convenient for you, let's leave as soon as possible."

"I'm in such a hurry, is Ming Gong afraid that there will be a tiger wolf in Xuzhou to eat me?"

The three of them laughed, but there was something else in the laughter.

Guo Ming knew in his heart that this must be what Cao Cao heard.

The gang in Xuzhou was suppressed a little too hard last time, at least they felt that they were suppressed too hard.

Now is not the time to shake these guys, Cao Cao can only give Guo Ming some real power and let him go to some other places.

He's convenient to kill people in those places, and he can also take these guys down.

Otherwise, something might be done.

"I will also let Yuan Rang go to the army as soon as possible, so that the girl will not suffer."

"Thank you Ming Gong, you are really understanding."

Cao Cao is a really smart person, and Guo Jia is not a fake smart master.

It's just that this group of people in Xuzhou who are not very smart still think they are really smart.

Damn such people, not now.

Guo Ming and Xiahoudun left Xuzhou on the same day, one went to the upper reaches of Surabaya and the other went to the lower reaches of Surabaya.

The two of them happened to completely cut off Surabaya.

At this time, it is still winter, and it is also the time to arrange the water strategy, and Bai Qi is one of the experts.

He immediately had the hydrology surveyed and found a place to be contained, both up and down.

Guo Ming took a closer look and realized that this was still a big job.

There are so many places that there must be hundreds of openings, and if you want to lift all the water veins, you need six or seven hundred components.

It is simply impossible to make so many components in the middle of winter for more than 100 days.

For Guo Ming, the biggest problem is that he hasn't found Xiao Ai to create something yet.

"Master, are you sure that the new creation needs to be cement?"

"yes, and it's the kind of cement that can be waterproofed. This time I'm going to do an underwater operation. ”

"Okay, do you need rebar?"

"Yes!"
