Isatis root is a common name. It is actually a traditional Chinese medicine made from the roots of woad, which are dried and ground into powder as the main ingredient.
Of course, there is no isatis root in this era, and even woad is not used to treat diseases these days.
That is the material for dyeing cloth.
The blue that is better than blue.
Of course, in this era, the main way to obtain blue dye is not woad, but polygonum. This thing also has certain medicinal value, but it is not as obvious as the medicinal effect of woad.
And whether it is woad or polygonum, both are commonly used in the army for dyeing military uniforms.
Therefore, when Zhang Xi went to the army to find a plant that he did not know whether it was woad or polygonum, and said that he wanted to treat Fa Zheng's illness, the medical officer tried his best to stop him.
I have never heard of using dyes to treat diseases. This kind of folk remedy that I don’t know where it came from is just nonsense.
Besides, Fazheng is not hopeless. The medical officer has followed the prescriptions in "Treatise on Febrile Diseases and Miscellaneous Diseases" to cool down Fazheng first. After Fazheng no longer has a fever, he can be nursed back to health slowly, although it will take a long time. It's a bit slow, but at least it's more reliable than using dyes to treat illnesses.
Zhang Xi, that depressed one. Did you know that this folk remedy in your mouth has been used for more than a thousand years and is the most common prescription for treating wind-heat and cold in later generations?
But there is no way. At this time, Banlangen is indeed not recorded in any medical books, and it is a folk remedy that cannot be more biased.
Zhang Xi couldn't defeat the medical officer, but Fa Zheng chose folk remedies.
It has to be said that the medical officer is still very capable. After two days of hard work, Fazheng finally no longer had a high fever and slowly regained consciousness.
But when 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 Fazheng's physical condition was already very bad. It was difficult for him to get up, not to mention that Liu Bei wouldn't let Fazheng get out of bed easily for fear of aggravating his condition.
Fa Zheng was quite desperate at first, thinking that he might not be able to make it in time for the Northern Expedition. Until he heard that Zhang Xi had a folk remedy that could quickly cure his illness.
Fazheng gritted his teeth and called Zhang Xi privately to ask what the folk remedy was.
When he heard that dyes were used to treat diseases, Fazheng was a little hesitant. Although he wanted to catch up with the Northern Expedition, Fazheng didn't want to die because of a folk remedy.
But Zhang Xi repeatedly assured that this thing is really not a folk remedy, it is really effective. Fa Zheng decided to take a gamble.
But this matter still cannot be circumvented. Medical officer Zhang Xi does not know how to distinguish between these woad and polygonum, let alone how to use them as medicine, so a medical officer is required to help.
The medical officer really couldn't resist these two idiots, and the patient himself agreed. As a medical officer, he just had to do his best.
It is not difficult for a medical officer to distinguish woad from a group of dyestuffs brought by Zhang Xi, and it is not difficult for the medical officer to use the roots as medicine. Finally, he boiled a bowl of isatis root potion with a strange taste. Handed over to Fa Zheng.
That taste. Really, Fazheng almost squirted out the first time he drank it.
It was so bitter.
But Fa Zheng is Fa Zheng after all, and he was so cruel to himself that he forced himself to hold back and drink it.
After finishing the drink, Fazheng sighed and rested restlessly, thinking that if the past two days went bad, the army would set off the next day. Fazheng felt that he didn't feel so uncomfortable anymore.
The medical officer was quickly called for a follow-up examination. The medical officer was also puzzled. Could it be that the roots of the dye plant could really be used as medicine to treat febrile diseases? !
If this were true, wouldn't he be able to become famous all over the world with this thing? !
Immediately, the medical officer became interested. Not only did he make a serious diagnosis for Fazheng, he also began to conduct research on isatis root.
There were no special research methods in this era. The most you could do was cut a piece and taste it, and then judge the medicinal properties of this thing based on medical records and your own experience. Of course, the most important method is actual testing.
Fa Zheng's status is relatively noble, and medical officers don't dare to do anything casually. They just boil medicine for routine treatment, but it is not difficult to find people with symptoms of febrile diseases these days.
Well, no matter what the medical officer thought later, at least Fa Zheng's body began to improve at a speed visible to the naked eye.
Zhang Xi was also puzzled. He couldn't figure out whether Fa Zheng itself was almost cured, whether isatis root was just accelerating improvement, or whether isatis root could really "cure all diseases"? !
Forget it, leave him alone.
Since Fazheng's health has improved, it will naturally not delay his continued service for Liu Bei Group in the future, and now Zhang Xi is going to lead the army.
Zhang Xi was appointed by Liu Bei as the front commander, that is, the vanguard of the army. He would lead 20,000 troops and clear the way for the army. He would set off a few days earlier than Liu Bei's army.
Under Zhang Xi's tent, this time he not only had Zhang Yi and Ju Fu whom he brought, but also Wei Yan, whose nose was not a nose and whose eyes were not eyes.
Zhang Xi was really confused. Didn't his lord Liu Bei know that this common man didn't get along with him? !
Why do you always have to partner with this guy every time there is a group battle? !
The last time we took Xichuan, Zhang Xi was the vanguard and Wei Yan was Zhang Xi's general.
This time out of Qishan, Zhang Xi was still the vanguard, and Wei Yan was still his general.
Not only Zhang Xi doesn't understand this problem, but even Wei Yan doesn't understand it either. Why does the lord think that two people are more suitable as partners? !
This reason was given by Liu Bei to Wei Yan. In fact, Wei Yan did not want to partner with Zhang Xi, so after the order was issued, he went to Liu Bei in private and tactfully confessed to Liu Bei that he and Zhang Xi did not get along.
This means that Wei Yan was Liu Bei's confidant in his early years. Otherwise, it would be difficult to tell Liu Bei face to face for this reason.
But what can Liu Bei say? !
You can't say that you, Wei Yan, have qualifications but not qualifications, you have popularity but you are not popular, you are not qualified to lead an army alone, and you are not happy to be partnered with others. Except for Zhang Xi who can fight with you regardless of past resentment, no one wants you at all, right? ? !
Therefore, Liu Bei could only tell Wei Yan that in all previous battles, Wei Yan and Zhang Xi had partnered the most, and they had some tacit understanding with each other, so they were the most suitable partners.
Of course, if Wei Yan is really not willing, Liu Bei will not force it, Wei Yan can also stay in the Chinese army and command his own Chinese army escort.
Obviously, Wei Yan was not happy.
The Chinese army guards who command Liu Bei must stay with Liu Bei. Unless Liu Bei himself encounters a major crisis, there will be no chance of meritorious service and reward.
Therefore, although he was not happy, Wei Yan still accepted to partner with Zhang Xi, and together they became the vanguard of the army and led the troops out of Qishan.
As for Zhang Xi, he didn't deliberately suppress Wei Yan just because he didn't get along with Wei Yan.
Zhang Xi now has three available generals. Wei Yan has the strongest ability and is also the most famous. Therefore, regardless of whether Zhang Xi ranks them according to reputation or ability, Wei Yan must be used in high priority.
Therefore, Zhang Xi divided the 20,000 soldiers and asked Wei Yan to lead 10,000 soldiers.
At the same time, Zhang Xi divided the remaining 10,000 soldiers, commanding Ju Fu to lead 3,000 soldiers as the outpost, himself and Zhang Yi to lead 7,000 soldiers as the middle army, and Wei Yan led 10,000 soldiers to guard the rear wing. The whole army quickly Go to Wudu County controlled by Cao Wei, prepare to enter Qishan Road from Wudu County, and strive to quickly pass through Qishan Road and enter Liangzhou.
But if you want to pass through Qishan Road and enter Liangzhou quietly, there is one place that you must first find a solution to.
It is really not suitable for Wudu County. Although Wudu County is located to the west of Hanzhong, due to the battle between Liu Bei and Cao Cao for Hanzhong, Wudu County was already severely infiltrated and destroyed by Liu Bei's group. It has not been destroyed until now. recover.
In addition, after Wei Yan became the governor of Hanzhong, he continued to harass and expand Wudu County. The current Wudu County is only nominally the territory of Cao Wei. In fact, the defense force is quite weak and can be attacked in one attack.
What Zhang Xi is really worried about is Qishan Fort.
This is a military fortress built by Cao Jun near the interruption of Qishan Road to monitor the enemy troops on Qishan Road.
Cao Wei actually knew the situation in Wudu County, and it was obviously impossible to expect Wudu County to stop Liu Bei, so he specially built such a military fortress to serve as an observation and warning function.
The current guard of Qishan Fort is named Gao Gang. This person is an unknown figure in both Cao Wei and Shu. But such an unknown person, relying on the favorable terrain of Qishan Fort, has managed to resist in history. The offensive of Zhuge Liang's Northern Expedition army was firmly nailed to the throat of Zhuge Liang's Northern Expedition road, effectively hindering the smooth flow of food routes for the Northern Expedition army.
Zhuge Liang's response at that time was to first send people to surround Qishan Fort without attacking by force. Then the army bypassed Qishan Fort and entered Liangzhou, capturing Tianshui, Nan'an and Anding counties.
But the problem is that the Qishan Fort cannot be conquered, and the food routes of the Northern Expeditionary Army are always under the threat of Qishan Fort. In addition, Wu Yi and Wei Yan later failed to attack Longxi County and Guangwei County, and Guo Huai held on to Shanggui again. With the reinforcements led by Zhang He, Zhuge Liang had to ask Ma Di to guard the street pavilion.
It can be said that Qishan Fort was the first problem on the Northern Expedition route, and this Qishan Fort, no matter how many times Zhuge Liang left Qishan, was always the first threat that the Northern Expedition army had to face.
In order to keep the food routes open for the Northern Expeditionary Army, this Qishan Fort must be captured.
But the problem is that this Qishan Fort is really difficult to fight.
The geographical location of Qishanbao is quite outstanding.
Qishan Fort is a military fortress built on a hill, and this mountain is in the middle of Qishan Road, directly blocking the north route of Qishan Road.
Moreover, there is only one mountain road in the southwest that can go up to this mountain. There are cliffs in other directions, which is quite easy to defend and difficult to attack. Qishan Fort is built on the mountain, and everything moving for dozens of miles around is under its nose. It is the best monitoring position.
What's even worse is that there are mountain springs on this mountain, and there is no shortage of water sources at all. In other words, as long as enough food and grass are stored, it will be difficult to capture Qishan Fort.
It's no wonder that Zhuge Liang's several Northern Expeditions in history only besieged Qishan Fort and never captured Qishan Fort.
There seems to be no other good way to do this except to encircle it and wait for it to run out of food.
But if you still deal with it this way, wouldn't it be just like in history, and your food route will always be under the threat of Qishan Fort? !
This is not what Zhang Xi wants to see.
