With Liu Fei's professional opinion, even if he was not very familiar with the geographical location of the Kwantung vassal states in this era, Liu Sheng also nodded slowly.

In the past ten years, Liu Sheng, as the prince, has received an elite education in the palace that is second only to the standard of the prince;

Not only Liu Sheng alone, but every prince with Liu Qi's blood has also received the same level of education.

As for the reason, it's also very simple;

- Unlike many dynasties in later generations, the princes of the Han family want to be crowned kings when they grow up.

Moreover, the feudal kings here are not the feudal kings and princes who were raised as pigs in later generations, but the princes and kings who have real power, and even absolute autonomy and autonomy!

In the words of the moment, it is: open the country and build the society.

It is no exaggeration to say that this level of education can be understood as follows: the princes of the Kwantung region, the per capita quasi-prince;

In case one day in the future, the Son of Heaven in Chang'an has three longs and two shorts, and there happens to be no son who can inherit the country, then the Kwantung princes basically count one by one, and if they bring one back, they can take the position of the Son of Heaven.

The reason for this is naturally to ensure that no matter how unexpected the situation is, it can ensure that the Han family is always in the hands of the Liu family.

Don't say it!

More than 20 years ago, this safety lock really played an important role!

- Emperor Xiaohui Liu Ying died, and then the 'heir', as the fourth son of Emperor Taizu Gao Liu Bang, became the 'loyal elder' in the mouth of the courtiers and hundreds of officials, and was able to enter the unification.

The next thing is very familiar to the big guys;

After Liu Heng, the acting king, succeeded to the unification, he began to 'cross the river and tear down the bridge' without hesitation!

In the name of an honest man, he ruled those old ministers who thought he was easy to bully and handle, and he sat on the throne in just a few years, not to mention, and finally got the temple number of 'Taizong' and the nickname of 'Wen'.

Especially after Liu Heng's death, the people of the world were all sad and weeping, even more sad than when Taizu Liu Bang died.

With this quality, in any dynasty in the future, you say that he was originally the prince of the prince, I'm afraid no one will believe it!

However, for the princes of the clan, as well as the princes who have not yet become princes, maintaining such a super-high level of cultivation standards has naturally led to some negative effects.

This negative impact is the reason why those dynasties in later generations would rather raise their clan relatives and vassal kings as pigs than cultivate them well;

At the same time, it is also an important reason for the emergence of "Cutting Domain" in the Chang'an court.

- The 'quality' of the clan is too high, and the threat to the central government is really big and outrageous······

Back to the map in front of you;

The elite education he received in the past was enough to support Liu Sheng, who was only eleven, to understand such a brief territory map that only had the vassal states and the capitals of each country.

However, just like the world map in later generations, which only had national markings but no topography or landforms, it was obviously still a little difficult to hope that Liu Sheng would see the obstacles that the Kwantung vassal states might encounter when they rebelled from such a territory map.

For example, Liu Fei Fangcai, who said 'If you want to appear outside Hangu Pass, you must first take Suiyang', Liu Sheng is not very comprehensible.

"Eh, Fifth Brother;"

"How do I remember Suiyang City, and it's not in a critical position like a pass?"

"If you can't take Suiyang, can't the rebels bypass Suiyang City and directly make a detour to raid Hangu Pass?"

Slightly puzzled, Liu Sheng did not forget to lower his head, and pointed to the area on the map, located east of Hangu Pass and west of Suiyang City.

"Besides, even if Suiyang is taken, there will be Xingyang and even Luoyang, the eastern capital, in front of the rebels!"

"Even take a step back and say: Even if all the outside of the pass is lost, isn't there still Hangu Pass?"

"I remember that during the Warring States Period, the Kwantung countries were united, and they also hit Hangu several times, but in the end, they were all blocked by the Qin State outside the Hangu Pass?"

"Father and Emperor can directly garrison heavy troops in Hangu Pass, why do you have to be so ······ to Uncle Liang?"

Liu Sheng was full of puzzled questions, and Liu Pengzu, who was provoked on the side, also nodded secretly, and then turned his equally puzzled gaze to Liu Fei, the fifth brother who already had a little murderous intent between his eyebrows.

In other aspects, even if the eight Liu Fei are tied together, they may not be able to compare to any of the two brothers Liu Pengzu and Liu Sheng;

But only this battle formation and march, the two brothers of this age are tied together, and I am afraid that they are not as good as half of Liu Fei's.

Seeing that the two younger brothers were confused about this, Liu Fei didn't talk and laugh anymore, and a solemnity and seriousness similar to Liu Qi today appeared on his face.

"If today's Han family is the same as the Qin State during the Warring States Period, then it is indeed as Xiao Jiu said: My father can put all his energy on the defense of Hangu Pass."

"In fact, this is indeed the case: as long as Hangu Pass is not lost, no matter how chaotic the Kanto region is, the war will basically not affect Guanzhong."

"But the most important point was ignored by Xiao Jiu······"

Speaking of this, Liu Fei raised his head with a stern face, and looked at Liu Sheng and Liu Pengzu's brothers, and they were full of worry.

"-My Han family, not the 'Han Kingdom'!"

"If the Kwantung princes raise troops to rebel, as long as they can send the rebels to Suiyang City, it will be a great earthquake in the world immediately!"

"If Suiyang City is broken, the rebels, let alone capture Hangu Pass;"

"But as long as the rebels appear outside Hangu Pass, and successfully form a formation and camp, the throne under my father's emperor will probably start to burn his ass······"

As he spoke, Liu Fei couldn't help but look at the two brothers deeply, then frowned and lowered his head, and swept his hand around the map.

"Furthermore: even if there is a rebellion from the clan, it is impossible to rebel completely, there will always be a few loyal and good families, who will send troops to Qin Wang at that time to help Hangu."

"If Suiyang is lost, then the princes in the eastern part of the Kwantung who have not rebelled, and the garrisons in the northern border passes, even if they want to go to support, it will be difficult to break through the rebels' defensive line."

"Therefore, in order to ensure that the rebels under their command are smoothly sent outside Hangu Pass, and at the same time, to ensure that they will not be flanked by other vassal soldiers and border garrisons who come to support them, the rebels must first capture Suiyang;"

"Only by capturing Suiyang can the rebels control the entire territory of Liang State, and no longer have any worries, and put all their attention on Hangu Pass."

"In other words: if there is really a rebellion of the princes and princes of the clan, then Suiyang City is equivalent to the temple and Sheji of my Han family!"

"——Suiyang City is here, Zongmiao and Sheji are here;"

"If Suiyang City is broken, there will be chaos in Guanzhong, and the undercurrents inside and outside the government and the opposition will surge, and the temple and the community will be unsafe."

"Father, it will be difficult to sit in the emperor's position safely······"
