In the evening, in the Bin Palace, Yuwen Weihan, who had finished dinner, played chess with his servants in his small study. This chess is unusual and is called "war chess". The rules are complicated but very challenging.

My father assigned him a homework, and the title of the homework was called "The Battle of Liaodong". Although he did not require "solving the problem", Yuwen Weihan attached great importance to it.

His father asked him to be the Grand Marshal of the Dynasty (heihei) to command a 200,000 army, to conquer Goguryeo, which occupied Liaodong, and restore the homeland of the four Han counties. This homework was difficult, but Yuwen Weihan was fascinated by it.

He wants to win to prove to his father that he has grown up.

Yuwen Weihan racked his brains tossed for several months, and his winning rate of playing war games was always very low. He could not play a coach, let alone challenge his father.

Yuwen Weihan was so anxious that he thought about all kinds of solutions, but he just couldn't win the training.

My father has set the beginning of this game. He has 200,000 troops, infantry, horse army and navy. He can choose to attack Liaodong by land or sea, transport troops directly to the hinterland of Goguryeo and directly attack the capital Pyongyang.

It can also advance in water and land, and attack at the same time from east to west, so that the Goguryeo army can lose sight of one thing.

This setting seems easy, Yuwen Weihan is full of confidence, but when he really started to go down, he realized that this was a fire pit.

By land, you have to start from Youzhou, leave Lulongsai, go to Yingzhou, then turn east, pass the Liao River and enter Liaodong.

It looks simple, but it is not simple at all: Lulong Road is small, and hundreds of thousands of troops are very congested when they go up. The water is flooded in the middle and lower reaches of the Liao River. In fact, it is not flat ground, but a swamp called "Liaoze".

Therefore, the army had to cross the dangerous Liaoxi Daze before it could reach Liaodong.

What is danger? Because Liaoze is said to be endless, not only muddy and difficult to move around, but also mosquitoes as numerous as cows. Every summer and autumn, flying can cover the sky and the sun. If someone or animal mistakenly enters it, it will be instantly sucked by mosquitoes.

Even if you are not sucked dry, you will get sick due to being bitten by mosquitoes.

The army had to cross such areas, and the number of non-combat casualties increased dramatically, while the accompanying baggage trucks could not walk directly in the swamp, and could only continuously build bridges and pave roads.

The number of households in Yingzhou is rare, and the local food produced cannot supply the needs of the army at all, so all the food and grass have to be transported from the rear.

Where is the rear? Hebei.

After a lot of trouble, the army set out from Youzhou in spring arrived in Liaodong by land. It was late summer. Facing the Goguryeo mountain cities built along the mountain, their teeth were even broken and they couldn't even be gnawed, and winter was coming.

Seeing that the food and grass were not available, I had to withdraw my troops, but was followed by the Goguryeo cavalry, which was so miserable.

It is difficult to fight by land. Yuwen Weihan changed his thinking and observed the "terrain". He planned to follow the "sea route" in the western coastal areas of Liaoxi, march along the coastline, and pass by the southern edge of Liaoze.

But this is not possible. The coastal areas of western Liaoning are water-stacked areas with many sandy moraines. They also cause heavy water during the rainy seasons in summer and autumn. The water is deep and the boat cannot be sailed, the water shallow and the carriage cannot pass through. The army cannot pass. They can only go to the Lulong Road to Yingzhou, cross Liaoze and fight in Liaodong.

If it is difficult to walk by land, then take the sea route. The soldiers board the boat in Laizhou, cross the sea directly to the opposite side, and land in the western coastal area of ​​Goguryeo, which is only a few hundred miles away from Pyongyang.

As long as you conquer Pyongyang, Goguryeo will be finished.

Yuwen Weihan thought so, but he lost the same miserable result.

Crossing the sea, intercepting bends and straightening, the idea is good, but the problem is that there is an elusive storm on the sea, and if you are not careful, the entire army will be wiped out.

Or the vanguard landed successfully and confronted the enemy, and the subsequent troops and food were crossing the sea, they were destroyed by a storm that suddenly came (die thrown out).

Later, there were no reinforcements and no food and supplies. The vanguard who came to Pyongyang City was wiped out.

Such a cruel setting made Yuwen Weihan often "extreme joy lead to sadness". When the situation was getting better, he lost to tears.

Such a heart-wrenching failure made him often wipe his tears afterwards. He finally won several times, but he was all based on his luck and did not encounter a storm when he walked on the sea.

Yuwen Weihan, who was "fighting repeatedly after repeated defeats", racked his brains to find a solution. He finally came up with a solution, which was to take measures based on the flaws of a rule and warn of the storm in advance.

A certain rule states: Storms all come from the southeast coast.

Yuwen Weihan thought about this abrupt rule carefully, and then a flash of inspiration flashed.

Southeast? Could it be that the storm came all the way from the southeast coast? How far is it to the southeast?

In the southeast corner of the chessboard, it is the trading base of the Maritime Bureau, the chicken coop at the northern end of Yizhou.

There is a kind of chess piece called a meteorological observation station that carries a letter from a flying pigeon. At first, Yuwen Weihan couldn't understand what this kind of chess piece was, but when he thought of the storm, he understood it.

Starting from the Jilong stronghold at the northern end of Yizhou, a meteorological observation station is set up, and points are arranged along the way to establish a storm early warning system.

Yuwen Weihan made this choice, so the rules of the game changed: when a storm appears, it will always "appear" in the southeast of Yizhou, rather than suddenly appearing in the waters of Laizhou.

Although such a storm moves very quickly, for the attacking party, there is time to avoid it. The landed soldiers and fleets crossing the sea can retreat in time to the harbor to shelter in time when they see something is not good.

The problem of burying the fish's belly has been solved, but the problem of storm interference still exists when walking on the sea. Although Yuwen Weihan's "winning rate" has increased, it is still far from the 50-50 game.

At this time, Yuwen Weihan began a new round of "Liaodong Battle", solemnly rolled dice, gathered troops, and began to cross the sea and attack.

A servant brought tea into the room. Seeing Yuwen Weihan's concentration, he left silently, turned around in the corridor, turned to the front yard study room, and replied to Yuwen Wen.

"The Lord, the Lord is playing war chess."

"Yeah, I got it, step down."

The servant took his leave, and Yuwen Wen imagined his son's crying expression and couldn't help but smile.

Goguryeo must be solved, but Yuwen Wen knew that he could not be anxious. If he wanted to win quickly like Yang Guang, he would have to end up with a quick defeat. Therefore, he had to prepare in advance, prepare for the battle and wait for the opportunity.

And he no longer needs to rely on new military achievements to prove himself. The opportunity to make military achievements is naturally the sons.

But letting the inexperienced sons take charge of the battle is not love, but harm, so Yuwen Wen must guide his sons slowly and let their sons grow up and stay until their shoulders are hard before they can shoulder the burden.

As he thought about it, Yuwen Wen turned his attention to the book he was reading.

Zhang Lihua and Chen Jam gave birth to a daughter and a son for him at the beginning of the year, forming a word "good". Now the two have recovered as they were. Although the little guys are not over one year old, they can still withstand the fatigue of long-distance trekking.

So Zhang Lihua and Chen Xian took their children from Xiyang, Huangzhou, and came to Chang'an.

And he has to make some preparations in advance so that he can name his son in the future.

There are naturally some specialties in naming a name, and it is not necessarily a rush to go in these few days. Therefore, in addition to preparing for the name of his son, Yuwen Wen also has a headache about what year he will choose after he ascends the throne.

I can only read the classics when I have time, hoping to find the right words in a flash of inspiration.

Now, the book he reads is "Shangshu Yao Dian".

The eyes fell on a passage.
