Zhu Wei didn't expect that Zhang Lu in Hanzhong would actually think of taking the initiative to take refuge in himself, which was really another unexpected joy.

It turns out that the territory controlled by Zhang Lu in Yizhou is mainly in Hanzhong County, Fuling County, Badong County, Ba County, and part of Ba County and Pasir County, which can be regarded as separated between Zhu Wei of Jingzhou and Liu Zhang of Yizhou.

However, Bajun is the place where Zhang Lu started, and many of his generals and subordinates are also in Bajun, so although Zhang Lu now takes Hanzhong as the core territory, he also attaches more importance to the land of Bajun.

But Liu Zhang has always wanted to get rid of Zhang Lu, a traitor, so he often sent troops to attack Zhang Lu.

Because of the terrain environment of Yizhou Shu is difficult to go to the blue sky, Liu Zhang can only take the two routes of Ba County and Zitong County to attack Zhang Lu, and find the way to attack Hanzhong where Zhang Lu is located, but it seems that Liu Zhang obviously prefers to take the road of Ba County, and often sends troops to attack Ba County first.

After all, Ba County is some distance away from Hanzhong County, and many times Zhang Lu has a helplessness beyond the reach of the whip.

However, Liu Zhang's side can send troops to attack Ba County at any time, so Liu Zhang simply appointed his relatively trustworthy in-law Pang Xi as the Taishou of Ba County, and let Pang Xi lead troops to attack Ba County many times.

Not long ago, Pang Xi gathered 30,000 troops from Jiangyang County and suddenly attacked Jiangzhou City (modern Chongqing area) in Ba County, and successfully captured Jiangzhou City.

Zhang Lu also suffered a drought at the end of last year, and some grain and grass were insufficient, so although he also wanted to send troops to recover Jiangzhou, he obviously had no certainty of victory, but the problem was that after Zhang Lu lost Jiangzhou City, Fuling County, located on the east side of Ba County, would also become an enclave out of Zhang Lu's control.

In this way, Zhang Lu is likely to lose the territory of Fuling County after losing Ba County, and then Pang Xi can continue to use troops from Jiangzhou to Pasi County, and eventually threaten Zhang Lu's land in Hanzhong.

It can be said that now Zhang Lu feels a great threat, and it is a little difficult for him to recover Ba County by himself, but he is unwilling to lose Ba County and Fuling County to Liu Zhang, and as a result, Zhang Lu Sizhi is ready to throw himself into Zhu Wei again and again.

So he sent an envoy to express his willingness to become Zhu Wei's foreign vassal, and only asked Zhu Wei to send troops to help recover Ba County.

Obviously, Zhang Lu also knew that Zhu Wei had Gan Ning's Jiang Jiao battalion stationed on the Jiangling side, so Zhang Lu was willing to let go of the peripheral areas of Yizhou under his control, and let Gan Ning lead the Jiang Jiao battalion from the Yangtze River waterway into Badong County, and then along the Yangtze River to Jiangzhou, or through the Fujiang River to Fuling County, and then through the Fujiang River to Jiangzhou.

Anyway, Zhang Lu gave up a passage for Zhu Wei's army to attack Jiangzhou directly, and Zhang Lu would rather give up Ba County and Fuling County to Zhu Wei than be occupied by Liu Zhang.

Because after Zhu Wei occupied these territories, he could help Zhang Lu block the attack of Liu Zhang's army, but let Zhang Lu live in Hanzhong with peace of mind.

To tell the truth, Zhang Lu's request this time is indeed an opportunity for Zhu Wei's army to enter Yizhou, and the most important thing is that Zhang Lu took the initiative to open the roads of Fuling County or Badong County, which is equivalent to allowing Zhu Wei's army to avoid the Shudao mountain range area on the outskirts of Yizhou, which is difficult to march, and can directly enter the core area of Yizhou.

If Zhu Wei's army can capture Jiangzhou, it will occupy a gateway in Yizhou that can enter the core Sichuan Basin of Yizhou.

Therefore, once Zhu Wei's army occupies Jiangzhou, it will also be of great benefit to Zhu Wei's capture of Yizhou in the future.

Wang Yuyan's suggestion to Zhu Wei was to accept Zhang Lu's request and let Gan Ning's Jiangjiao battalion send troops, and at the same time, he could also transfer Zulang's Yueshan battalion to assist.

Now Zulang's Yueshan battalion has infiltrated the southern Yizhou and northern Jiaozhou regions through Jingnan's conquest of the barbarians, and at the same time, under Pang Tong's planning, there is no need for Zulang's Yueshan battalion to personally send troops to do it, basically let some attached barbarian warriors help to conquer the wild barbarians in the mountains like mercenaries, and forcibly relocate the barbarian tribes hidden in the mountains to the outside of the mountains like slaves.

It can be said that Pang Tong only used some benefits to lure, so that the barbarians who were already fighting with each other did not hesitate to swing their knives and slash at other barbarian tribes in the mountains, and then use the population of these barbarian tribes in exchange for benefits.

Although there seems to be a story of Meng Huo rebelling with the southwestern barbarian tribes in the original Romance of the Three Kingdoms, in fact, Meng Huo still belongs to the familiar barbarians who have long been in contact with the Han people in the outside world, and many living habits have been assimilated by the Han people, but more barbarian tribes are still hidden in the mountains from outsiders.

In this way, under Pang Tong's plan, it is equivalent to letting many mature barbarian tribes deal with the barbarian tribes, even if the process will be more cruel, but it can indeed add population labor to Jingnan's side.

Of course, many barbarians who were originally located in the mountains of Jiaozhou and Yizhou were also instigated by Pang Ji's conspiracy to fight each other, so as to send prisoners of war to Jingnan to exchange the salt, grain and other materials they needed.

It can be said that the main task of Zulang's mountain crossing camp now is only to sit in the local town and then receive the population sent by the barbarians, and there is no need for them to go into the mountains to personally conquer it.

It's just that the barbarian warriors under the control of the Yueshan camp are also 30,000 or 40,000 people, and to be honest, the existence of these barbarian warriors is already a bit of a hidden danger.

Therefore, Wang Yuyan felt that this time it was completely possible for Zulang's Yueshan battalion to take these hired barbarian warriors from Wuling County to Fuling County, join Ganning's Jiangjiao camp, and attack Jiangzhou City together.

After that, Gan Ning, Zu Lang, and Pang can also be unified to wait for the opportunity to attack Liu Zhang in Yizhou, and in the process, some barbarian warriors will be consumed, so as not to lose the tail in the future.

At the same time, it is now the autumn harvest season, and the new grain in Jiangdong, Yuzhang, Jingnan, Jingzhou and other places will be ripe, which can fully support the needs of the battle of Yizhou.

And judging from the current situation, the Battle of Shouchun has just ended, and Zhu Wei will not immediately launch any war against Cao Cao for the time being, but there is enough time for Zhu Wei to make a move against Yizhou.

It can be said that now Zhang Lu takes the initiative to vote, which is a rare opportunity.

Zhu Wei was also a little tempted when he heard this, originally Zhu Wei had a plan to conquer Yizhou, but later after listening to Zhuge Liang's suggestion, he felt that the land of Yizhou was just a small profit, and Zhu Wei should focus on the overall situation of the Central Plains.

At the same time, there are also many practical difficulties in conquering Yizhou, and the Shu land surrounded by continuous mountains is as difficult as the Shu Road to the sky, which is really a natural barrier for Liu Zhang in Yizhou, but now it is rare for Zhang Lu to take the initiative to let the outer mountains of Yizhou open, so that Zhu Wei's army can directly kill the hinterland of Yizhou, and it does reduce a lot of difficulty in attacking Yizhou.

In addition, Zhu Wei only needs to send a partial army to attack Yizhou, and the main troops used will also be barbarian troops, no matter whether this victory or defeat, as long as it can open up the situation in Yizhou, it will be advantageous.

Therefore, Zhu Wei's heart was already moved, and then he also found Jia Xu, Lu Su, Zhou Yu, Sun Quan, Zhuge Liang and others to discuss......
