The root of woad is a common name, in fact, it is a kind of Chinese patent medicine made by drying the root of woad and grinding it into powder as the main ingredient.

Of course, in this era, there is no banlan root, even woad, and this year is not used to cure diseases.

That's the material from which the cloth is dyed.

The blue that is out of the blue.

Of course, in this era, the main way to obtain blue dye is not woad, but indigo, which also has a certain medicinal value, but it is not as obvious as the medicinal effect of woad.

And whether it is woad or indigo, it is always available in the army and is used to dye military uniforms.

Therefore, when Zhang Xi went to the army to find a plant that he didn't know whether it was woad or indigo, and said that he wanted to treat Fazheng, the medical officer was desperately blocked.

I've never heard of dyes to cure diseases, and this kind of home remedy that I don't know where to get it is just nonsense.

Besides, Fa Zheng is not incurable, the medical officer has already followed the prescription on "Treatise on Typhoid Fever and Miscellaneous Diseases", first cool down Fa Zheng, and wait until Fa Zheng no longer has a fever, you can slowly recuperate, although the time is a little slower, but at least it is more reliable than using dyes to treat diseases.

Zhang Xi that depressed. Do you know that this home remedy in your mouth has been used for more than a thousand years, and it is the most conventional prescription for the treatment of wind, heat and cold in later generations.

But there is no way, at this time, Banlangen is indeed not recorded in any medical books, it is a partial home remedy that can no longer be biased.

Zhang Xi couldn't resist the medical officer, but. Fa Zheng chose a home remedies.

I have to say that the medical officer still has the ability, and after two days of hard work, Fa Zheng finally stopped having a high fever and slowly regained his consciousness.

But as soon as Fa Zheng heard that the medical officer suggested that he stay in Hanzhong to recuperate and not go out with the army, Fa Zheng immediately disagreed.

But now Fa Zheng's physical condition is already very bad, and he has a hard time getting up, not to mention that Liu Bei doesn't let Fa Zheng get out of bed and move around easily at all, for fear of aggravating his condition.

Fa Zheng was originally quite desperate, thinking that he might not be able to catch up with this Northern Expedition. Until he heard that Zhang Xi had a home remedy that could cure his illness quickly.

Fa Zhengyi gritted his teeth, brought Zhang Xi in private, and asked what the home remedy was.

As soon as he heard that dyes were used to treat diseases, Fa Zheng was also a little hesitant, although he wanted to catch up with the Northern Expedition, but Fa Zheng didn't want to die because of a home remedy.

But Zhang Xi repeatedly assured that this thing is really not a home remedies, it really works. Fa Zheng decided to take a gamble.

But this matter still can't be bypassed, the medical officer Zhang Xi doesn't know how to distinguish between these woad and indigo, let alone how to enter the medicine, and the medical officer has to help.

The medical officer really couldn't resist these two goods, and the patient himself agreed, and he, the medical officer, did his best.

Distinguishing woad from a group of dye grass brought by Zhang Xi is not a difficult task for a medical officer, and it is not difficult for a medical officer to put the roots into medicine. In the end, I boiled a bowl of the strange taste of Banlan root potion and handed it to Fazheng.

It's a taste. Really, Fa Zheng almost squirted it out for him the first time he drank it.

It's just too bitter.

But Fa Zheng is Fa Zheng in the end, and he is ruthless enough to himself, so he holds it back and drinks it.

After drinking, Fa Zheng sighed, restlessly lying down to recuperate, thinking that if these two days were not good, the army should set off the next day, Fa Zheng felt as if he was not so uncomfortable.

Hurriedly called the medical officer, so that the medical officer re-examined the medical officer and wondered, could it be that the dye plant root can really be used in medicine to treat warm diseases? !

If this is true, then wouldn't he be able to make a name for himself with this thing?!

Immediately, the medical officer also took it seriously, and not only seriously diagnosed Fazheng, but also began to study Banlan root.

In this era, there was no special research method, at most it was to cut a slice and taste it, and then judge the medicinal properties of this thing according to medical records and one's own experience. Of course, the most important method is to experiment.

Fa Zheng's identity is relatively noble, and the medical officer doesn't dare to mess around casually, it's just a routine medicine treatment, but it's not difficult to find some people with symptoms of fever in these years.

Hawkers, no matter what the medical officer thinks about it in the future, but at least Fazheng's body is beginning to improve at a speed that is visible to the naked eye.

Zhang Xi also wondered, he couldn't figure out whether this was Fazheng itself and was about to get better, Banlangen was just getting better, or was Banlangen really able to "cure all diseases"? !

Forget it, leave him alone.

Since Fa Zheng's health has improved, it will naturally not delay him from continuing to work for Liu Bei Group in the future, and now. Zhang Xi is going to lead the army and set off.

Zhang Xi was appointed by Liu Bei as the front governor, that is, the vanguard of the army, leading 20,000 troops to open the way for the army, and would set off a few days earlier than Liu Bei's army.

And under Zhang Xi's account, this time there are not only Zhang Yi and Jufu brought by himself, but also Wei Yan whose nose is not a nose and his eyes are not eyes.

Zhang Xi really wondered, didn't the lord Liu Bei know that this puppet was not compatible with him?!

Why do you always let yourself partner with this puppet every time you have a group fight?!

The last time Xichuan was taken, Zhang Xi was the vanguard, and Wei Yan was Zhang Xi's general.

This time out of Qishan, Zhang Xi is still the vanguard, and Wei Yan is still his own general.

This question, not to mention that Zhang Xi doesn't understand, even Wei Yan doesn't understand either. Why does the lord think that the two of them are more suitable partners?!

This reason was told by Liu Bei to Wei Yan, in fact, Wei Yan didn't want to partner with Zhang Xi, so after the order was issued, he deliberately found Liu Bei in private, and euphemistically confessed to Liu Bei that he did not agree with Zhang Xi.

This is also Wei Yan is Liu Bei's confidant in his early years, otherwise this kind of reason is really difficult to say to Liu Bei face to face.

But what can Liu Bei say?!

You can't say that you Wei Yan have no qualifications, you want popularity and no popularity, you are not qualified to lead an army alone, and others are not happy to partner with others Except for Zhang Xi can fight with you regardless of his previous suspicions, you have no one to want at all, right?!

Therefore, Liu Bei can only tell Wei Yan that in all the battles, Wei Yan and Zhang Xi have the most partners, and they have some tacit understanding with each other, so they are the most suitable partners.

Of course, if Wei Yan is really unhappy, and Liu Bei does not force it, Wei Yan can also stay in the Chinese army and lead his own Chinese army escort.

Obviously, Wei Yan was not happy.

The Chinese army guards who led Liu Bei definitely had to stay by Liu Bei's side, so unless Liu Bei himself encountered a major crisis, how could he have the opportunity to be rewarded for his meritorious service.

Therefore, although he was not happy, Wei Yan still accepted to partner with Zhang Xi, become the vanguard of the whole army together, and lead the troops out of Qishan.

As for Zhang Xi, he did not deliberately suppress Wei Yan because he disagreed with Wei Yan.

Zhang Xi now has three available generals, and Wei Yan's ability is the strongest, and at the same time, he is also the most famous, so Zhang Xi has to reuse Wei Yan no matter whether he is ranked according to his fame or ability.

Therefore, Zhang Xi divided the 20,000 soldiers and let Wei Yan lead 10,000 troops.

At the same time, Zhang Xi divided the remaining 10,000 soldiers again, ordered Jufu to lead 3,000 soldiers as outposts, and took Zhang Yi to lead 7,000 soldiers as the middle army, and Wei Yan led 10,000 troops to guard the rear wing, and the whole army hurried to Wudu County controlled by Cao Wei, preparing to enter Qishan Road from Wudu County, and strive to quickly pass through Qishan Road and enter Liangzhou.

And to pass through Qishan Road and quietly enter Liangzhou, there is a place that must be solved first.

It is really not suitable for Wudu County, although Wudu County is blocked in the west of Hanzhong, but because of the battle between Liu Bei and Cao Cao in Hanzhong, Wudu County has been infiltrated and destroyed by Liu Bei's group, and it has not been restored until now.

In addition, after Wei Yan served as the Taishou of Hanzhong, he continued to harass and expand Wudu County, and the current Wudu County only nominally belonged to Cao Wei's territory, but in fact, the garrison force was quite weak and could be attacked at once.

What Zhang Xi is really worried about is Qishan Fort.

This is a military fortress established by Cao's army near the break of Qishan Road to monitor the enemy army in Qishan Road.

Cao Wei actually knew the situation in Wudu County, and it was obviously impossible to count on Wudu County to block Liu Bei, so he specially established such a military fortress to serve as an observer and vigilance.

The current guard of Qishan Fort is called Gao Gang, this person, whether in Cao Wei or Shuzhong, is a lonely and unknown figure. But it was such an unknown junior, relying on the favorable terrain of Qishan Fort, to resist the offensive of Zhuge Liang's Northern Expedition army in history, and nailed to the throat of Zhuge Liang's Northern Expedition Road, effectively hindering the smooth flow of the grain route of the Northern Expedition army.

At that time, Zhuge Liang's countermeasure was to first send people to surround Qishan Fort and not attack it, and then the army bypassed Qishan Fort and entered Liangzhou, and captured Tianshui, Nan'an, and Anding counties.

But the problem is that Qishan Fort is not down, and the grain route of the Northern Expedition army has always been under the threat of Qishan Fort, plus later Wu Yi and Wei Yan's attack on Longxi County and Guangwei County was not smooth, Guo Huai held on to Shangqi again, and waited for reinforcements led by Zhang He. Zhuge Liang had to let Ma Tan go to the street guarding pavilion.

It can be said that Qishan Fort is the first problem on the Northern Expedition route, and this Qishan Fort, no matter how many times Zhuge Liang goes out of Qishan, is always the first threat that the Northern Expedition army will face.

In order to unblock the grain route of the Northern Expeditionary Army, this Qishan Fort must be taken.

But the problem is that this Qishan Fort is really hard to fight.

The location of Qishan Fort is quite outstanding.

Qishan Fort is a military fortress built on a hill, and this mountain, it is in the middle of Qishan Road, directly blocking the route north of Qishan Road.

And this mountain, only the southwest direction has a mountain road to go up, the other directions are cliffs, quite easy to defend and difficult to attack, Qishan Fort is built on the mountain, dozens of miles of movement are under its nose, is the best monitoring position.

What's even worse is that there is still mountain spring water on this mountain, and there is no shortage of water at all, that is, as long as enough grain and grass are hoarded, it will be difficult to take this Qishan Fort.

It is no wonder that Zhuge Liang in history only besieged Qishan Fort on several northern expeditions, and never captured Qishan Fort.

This place, except for the siege and not attacking, and waiting for its food to destroy itself, it seems that there is really no good way.

But if you still deal with it like this, wouldn't it be the same as in history, and let your grain route always be under the threat of Qishan Fort?!

This is not what Zhang Xi wants to see.
