Two days later, Liu Biao was advised by his father-in-law Cai Wei to feast on the day of the famous man in Xiangyang.

Pang Degong, Huang Chengyan and others naturally attended the banquet, and the rest also included Wang Cang, Song Zhong and other young talents.

The process of the feast is naturally not the point, so there is no need to repeat it.

It is nothing more than a group of celebrities debating scriptures, exchanging views and stories, and talking about looking forward to the general trend of the world.

After three rounds of drinking, the conversation gradually became richer, and suddenly someone reported that there was a young talent Zhuge Liang, the nephew of Yuzhang Taishou Zhuge Xuan, and he had something important to ask the envoy.

Everyone didn't react for a while, and they didn't know whether to persuade Liu Biao to meet him.

However, Huang Chengyan reacted first, and made an excuse to propose to meet him - I don't know if Huang Chengyan spontaneously did this, or if he was pestered by his daughter in the past few days, and had other plans.

"In that case, let's see." Liu Biao also pushed the boat down the river and followed the advice of his brother-in-law.

After Zhuge Liang entered, there was no need to mention some etiquette, and then asked Liu Biao as planned, and finally took out a silk silk, presented it with both hands, and said earnestly:

“…… Zhen Rong was canonized by the imperial court because of his uncle, but he was afraid that his uncle would gain a firm foothold and have many dreams at night, so he eagerly raised troops to attack. Danyang Sun Ce also made a move, reconciled with Zu Lang, and went against the current from Dangtu, wanting to do wrong.

Since the beginning of winter, Sun Ce has completely pacified Wu County, conquered Xu Gong, and has been raising troops for several months. Originally, it was rumored that Sun Ce wanted to meet Wang Lang first and then covet Yuzhang in the coming year. I never wanted to be stimulated by the canonization of the imperial court, and I also wanted to eradicate the troubles when my uncle's foothold was not stable, so that the king could only observe it. ”

Of course, Sun Ce has no intention of attacking Yuzhang now, and his current plan is most likely to deal with Wang Lang first in the coming year.

But Zhuge Liang knew that he had to say this in order to stimulate Liu Biao's sense of crisis.

Zhen Rong and Liu Biao have no enmity, if it is just a threat from Zhen Rong, the priority is not high enough.

Sun Ce and Liu Biao are enemies of killing their fathers, once Yuzhang County completely falls into the hands of Sun Ce, then he will directly border Liu Biao's Jingzhou, and will be in close contact with Jiangxia Huangzu.

As for the urgent document that Zhuge Liang handed over, the words on the silk were of course written by him just three days ago.

Zhuge Jin believes in his younger brother's IQ, and he also knows that he is thousands of miles away and does not know the first-line situation in Jingzhou, so he can't give his younger brother ideas.

will be outside, and the king's order will not be affected.

Those who can win but do not control will win, and there will be no good end to remote micro-operation.

Therefore, Zhuge Jin's family book only mentions several possible escape plans to inspire his younger brother's thinking, for reference only.

In the end, the specific refinement and implementation were all done by Zhuge Liang himself according to the actual situation.

Zhuge Jin also fully trusts his younger brother, so he dares to hand over the blank silk with a big seal to Zhuge Liang to fill in by himself, believing that Zhuge Liang can make good use of it.

……

At this moment, Liu Biao saw the distress document stamped with the seal of Yuzhang Taishou and the captain of the Peaceful Commander, of course, it was not suspected that it was fake.

Usually, he doesn't care whether to rescue Zhuge Xuan or not, and when it comes to Sun Ce, he must release people.

But Liu Biao's temperament is still indecisive after all, he is in his fifties, and he is easy to hesitate when he is old.

After a little hesitation, Liu Biao really asked Zhuge Liang if he was sure and persuaded him not to hit the stone with an egg.

Zhuge Liang just threw out a reassuring statement for Liu Biao, as well as a new proposal:

"Envoy, the kid has a little friendship with Gan Sima in Fancheng, Gan Sima is also a righteous person, he is willing to escort me to Jiangxia, and I implore you to be accommodating! In addition, the kid had a reluctant request, begging the envoy to write a letter to the Jiangxia Huangfu Jun to persuade the Huangfu Jun to send troops nearby to help his uncle. This is also for the safety of Jingzhou and the refusal of Sun thieves to stay away from the state. ”

This request made Liu Biao think about it for a long time.

He knew Huang Zu very well, Huang Zu was the emperor of the soil in Jiangxia, and he couldn't command it.

If Huang Zu was willing to help Zhuge Xuan, he would have done so long ago last year.

This time, if he writes a book again, Huang Zu may not agree to send troops.

Even so, there is nothing wrong with writing a letter in vain and letting the Zhuge family accept their personal feelings.

Anyway, if he doesn't send troops in the end, the Zhuge family will also read his good, and hate Huang Zu for not saving him when he sees death and not listening to the orders of the state pastor.

If Huang Zu sent troops, it would not hurt, after all, it would expand the overall power of Jingzhou.

After much consideration, Liu Biao felt that there was no big problem in all aspects, and finally pushed the boat down the river and approved Zhuge Liang's invitation.

He wrote a letter for Zhuge Liang to bring to Huang Zu, and also allowed him to take Gan Ning to guard all the way.

Zhuge Liang breathed a sigh of relief.

In fact, if he just wants to leave Xiangyang, he doesn't have to be so troublesome, because the guards around Xiangyang are not strict.

Historically, Gan Ning wanted to go to Jiangdong, and on the way from Fancheng to Jiangxia, no one cared about it at all.

What is really strictly managed is precisely the place in Jiangxia County that passes through Xiakou. It was the junction of Jingyang and Jingyang, and Huang Zu's patrol army patrolled the river day and night.

After getting Liu Biao's letter, he and Gan Ning will be able to pass through Jiangxia smoothly and will not be blocked, which is the key to this trip.

As for Huang Zu not sending additional troops to help in the war, Zhuge Liang didn't take it seriously at all, and he didn't count on Huang Zu's soldiers.

Huang Zu and Zhuge Xuan are close at hand, but they have been seeing death and not saving them, and even if they find an excuse to disobey the order and not save them after seeing Liu Biao's order, it will leave a pretext for the Zhuge family to resent Huang Zu in the future.

……

Zhuge Liang completed all the formalities on the Xiangyang side, and finally set off in danger.

He also fooled Gan Ning, who was eager to make meritorious contributions, and other robes who fled from Yizhou with him, and escorted the Zhuge family to Jiangxia.

When Gan Ning fled from Ba County the year before last, he brought nearly a thousand troops with him, but more than 100 people had been lost, and now there are barely seven or eight hundred left.

Those lost troops were all lost in the battle with Zhang Ji and Zhang Xiu earlier this year.

When Gan Ning fled to Jingzhou, there were two other grassroots generals in Yizhou who were about the same level as him, Shen Mi and Lou Fa, who fled together. And Lou Fa had already died in the Battle of Zhangji in the fall, and Shen Mi still had two or three hundred parts left.

Gan Ning Shen Mi combined, the total strength barely exceeded 1,000, and they were divided into more than 30 large and small warships and went down the river.

Gan Ning's troops obviously paid more attention to the speed of coming and going, so the whole army did not even have a large fighting ship, let alone a building ship.

All of them are long, narrow and streamlined ships that can only carry about 50 people, the freeboard is very low, and there are oars holes on the side of the ship, and the speed of the sail and oars is like flying.

Although the group experienced a little twists and turns before setting off, Zhuge Liang soon found that Gan Ning's level of boat driving was very good, and the speed advantage could completely make up for the delayed time.

Nothing happened along the way, and Zhuge Liang was on the boat every day pondering the secret scroll that his eldest brother gave him.

and a few days before he left, Huang Yueying gave him the box of triangle boards.

Use a ruler to measure the length of the hypotenuse of the triangle piece by piece, and then record the measured trigonometric function value and the value of the common integer root number in a number table for direct query and transcription when used in the future.

If Zhuge Jin is here, he will definitely be dumbfounded when he sees the second brother's learning method like this-

This is also so specially pragmatic that the counting table is not calculated by calculation, but measured with a ruler.

Math classes can rely on experiments to obtain data, which is really eclectic.

In just three days, Gan Ning traveled 800 miles down the Han River and arrived in Jiangxia from Xiangyang.

And Zhuge Liang also finished the last remaining bit of knowledge in junior high school mathematics after three days of meditative study, and the "Junior High School Physics and Optics Part - Below" (of course, Zhuge Jin's original text is not named like this) given by his brother.

In the next step, he was going to take out the scroll of "Preliminary Application of Optical Geometry in Water Conservancy Survey" and finish reading it on the way from Jiangxia to Chaisang.

However, when the fleet passed through Jiangxia, it was still slightly delayed.

Huang Zu's troops blocked the fleet, and it took half a day to spread the word, and Zhuge Liang took the letter of help from Liu Biao and met Huang Zu himself.

Huang Zu is a stout military general with a face full of steel needles and short beard, and he is nearly fifty years old.

After seeing Liu Biao's letter asking him to send troops to help Zhuge Xuan, Huang Zu did not dare to openly disobey for no reason, but he still found various excuses to delay.

This is not to say that the enemy situation is not serious, or that there are false positives, and that it needs to be re-explored. That is to say, in a hurry, the Jiangxia Navy was unprepared and could not be pulled out for a while.

Strictly speaking, Huang Zu's first excuse was really crooked - because the hostile situation on Yuzhang's side was indeed not severe.

Sun Ce has indeed not spread his ambitions to the direction of Yuzhang, and he is still thinking about beating Wang Lang after the beginning of spring.

These so-called "grim military situations" were originally made up by Zhuge Liang.

So Zhuge Liang didn't talk too much, just pretended to beg bitterly to no avail, and then retreated with a bitter face, asking Huang Zu to at least let him and Gan Ning go to Yuzhang for reinforcements.

Advancing two and retreating one, Huang Zu had no excuse to refuse, so he had to let him go.

……

The flotilla went down the river and sailed for another two days.

When Zhuge Liang finished reading and re-rolling the secret volume of "Preliminary Application of Optical Geometry in Water Conservancy Survey", the fleet had already sailed into Poyang Lake.

Gan Ning makes people look carefully, and Zhuge Liang is also rare to go on the lookout bucket and watch the endless Poyang Lake scenery, and the mood is quite magnificent.

After looking at it for a while, Zhuge Liang suddenly saw several boats appear on the horizontal line in the distance, as small as mustard seeds.

Zhuge Liang remembered the knowledge he had just learned in the secret volume, and casually asked Gan Ning: "Xingba, can you see the ship on the other side?" What is the general length of this kind of ship? ”

Gan Ning also put up the pergola with his hand, and squinted for a while: "The largest one should be a fighting ship that can carry three hundred people, and it should be twelve zhang long." ”

Zhuge Liang took out a ruler, straightened his arm and compared, and asked, "In your estimation, how far is this ship from us?" ”

Gan Ning made a rough estimate based on experience, and said casually: "There must be six or seven miles, right?" ”

Zhuge Liang: "My arm is three and a half feet long, and the twelve zhang ship is only two minutes long on this ruler, which has shrunk by 6,000 times. The ship was no more than six thousand times the length of an arm's length from us, that is, more than twenty thousand feet, more than nine and a half miles. ”

"Can you see that size? Maybe a millimeter can be a mile away. ”

Gan Ning rolled his eyes, and didn't bother to care about this kind of nonsense that couldn't be verified. He felt that even if Zhuge Liang's method was correct, the error would be very large.

He was about to find another excuse to scold Zhuge Liang back.

But as the opposite fleet approached, seeing more and more clearly, Gan Ning suddenly shouted and diverted the topic:

"That fleet is flying the banner of Yuan Shu! Let's turn around the upwind to avoid accidents! ”

Zhuge Liang's eyesight was indeed not as sharp as Gan Ning's, and he hurriedly lay on the side wall of the lookout bucket, staring at the distance.

After a while, the two fleets adjusted their course and changed from hedging to sideways staggering, and Zhuge Liang could roughly see all the ship types on the opposite side.

Zhuge Liang's heart moved, and he hurriedly explained to Gan Ning: "It may be my eldest brother's fleet!" He may have played the Yuan Shu banner just to paralyze the enemy and facilitate the voyage all the way! Light up that pile of red smoke I let you lay in advance! ”

Gan Ning was stunned for a moment, and then remembered that early this morning, Zhuge Liang handed him a box of fire-starting things and asked him to spread them on a stone platform high in the stern.

It is said that this thing ignites very quickly, and there is red smoke after burning, which is very eye-catching. It was a token that his eldest brother sent from Guangling last time and was convenient for the meeting teacher.

At that time, Gan Ning still felt that this thing was too troublesome to use, and burned things on a wooden boat, and one accidentally burned the boat.

So much so that before he anchored from Jiangxia, he specially followed Zhuge Liang's instructions to make a few stone war horse drinking troughs on the shore, and poured the fuel that led the fire and smoke into the stone trough to prevent the fire from spreading.

Fortunately, Gan Ning is still neat, even if he doesn't understand, he will implement it.

It didn't take long for Zhuge Liang's boat to finally burn red smoke, and almost at the same time, red smoke also burned on the opposite fighting ship.

Zhuge Liang no longer had any doubts, so he asked Gan Ning to lean over immediately.

Gan Ning looked suspicious: "This can be confirmed?" ”

Zhuge Liang spread his hands: "Who have you ever seen who can burn this specific color of smoke?" This is naturally the secret recipe that my eldest brother has come up with with ingenuity! ”

Gan Ning was right when he thought about it, so he had to admire.

It seems that the Zhuge brothers are all people with endless ideas, and if they follow them, as long as they listen to the command well, they should be able to make contributions.

You just need to be responsible for using the knife.

The two fleets quickly approached, Zhuge Liang searched for a while, and finally on the rear deck of the opposite fighting ship,

I saw a man who was more than eight feet tall, wearing a red brocade robe and a seven-ring jade belt around his waist.

"Big brother! I am here! I'm Ah Liang! ”

With Zhuge Liang's greeting, Zhuge Zhi Zhuge Lan also wore a gauze curtain hat, quietly came out of the cabin, and squeezed to Zhuge Liang's side.

Following the direction of his wave, he found the location of the eldest brother.

"The eldest brother is really famous, this pomp and circumstance of leading the troops, some people believe it if they say they are generals." Zhuge Zhi and Zhuge Lan all worshipped.

Zhuge Jin on the opposite side also saw the greetings of his younger siblings, and secretly called luck in his heart:

He was only fourteen years old when he was separated from his second brother, and now he is sixteen and a half years old and about seventeen.

The young man hasn't seen each other for nearly three years, and the change is very big, if he admits his mistake, won't he arouse the suspicion of the second brother?

On the other hand, his own appearance should not have changed much, from nineteen to twenty-one and a half years old, his appearance has stopped changing.

Zhuge Jin hurriedly stared at Zhuge Liang, and quickly recognized it clearly, so as not to reveal flaws when the two ships met after a while.

Fortunately, it only took him a few seconds to settle down:

It's okay, you won't be mistaken!

Sure enough, the most handsome one on the whole ship was Zhuge Liang, and the gap between him and the others next to him was very big.
