Under one person: I, Zhang Zhiwei, the arrogant Zhang.

"Does Senior Brother Zhang know this person?"

"Who in the world doesn't know Senior Brother Zhang? Isn't it normal for us to know each other?"

Seeing Zhang Sanjia paying his respects to Zhang Zhiwei, a group of little brothers behind him whispered.

"Long time no see, how are you these days, Brother Sanjia?"

Zhang Zhiwei walked over, took the wooden basin containing the baby, and handed it to the little brothers behind him.

The younger brothers took it in a hurry. The young and middle-aged people were most likely to survive the disaster, and this was the first time they had encountered a baby, so they quickly began various examinations.

Zhang Zhiwei exchanged greetings with Zhang Sanjia.

Zhang Sanjia first thanked Zhang Zhiwei for his guidance, which helped him, who was somewhat confused, to find his own path in life.

"This is all your own choice, no need to thank me." Zhang Zhiwei waved his hand and said.

Zhang Sanjia opened his mouth, wanting to persuade Zhang Zhiwei to join in. With Zhang Zhiwei's ability, if he joined in, he would definitely be a great help, but in the end, no words of persuasion came out.

Because, even he was guided by Zhang Zhiwei, which means Zhang Zhiwei knew everything. Everyone has their own aspirations. It is already very rare for Xiao Tianshi to be a monk, not like those immortal figures in the legends, hiding in the mountains and ignoring the sufferings of the world. How can he ask for too much?

"I already know why you came here, and I have already prepared the things for you. Please go and come back as soon as possible."

Zhang Zhiwei casually threw a thumb-sized yellow bag to Zhang Sanjia.

"This is..." Zhang Sanjia didn't quite understand.

"This is a magic weapon, the Devouring Sac, refined by Tiangongtang. Don't underestimate it because it's small. There's a different world inside. There's a storage space of several square meters. Everything you want can be stored in it." Zhang Zhiwei said.

Tiangongtang also contributed to the flood relief efforts this time by lending out several sacs. Zhang Zhiwei bought one to store the medicines for this time.

"Mustard seed space? I've only heard of this kind of thing, but never seen it before." Zhang Sanjia held the Devouring Sac carefully and said, "I'm just a warrior, and I know very little about magical instruments. How do I use this treasure? Do I need to recognize its master?"

“You don’t need to recognize the master, but there are some requirements for sexual power. You must concentrate your mental strength and then sink your mind into it. Then you can sense the items inside and access them freely according to your thoughts.” Zhang Zhiwei said.

"That means ordinary people can't use it." Zhang Sanjia said.

Zhang Zhiwei nodded.

Zhang Sanjia was a little disappointed, but then he followed Zhang Zhiwei's instructions, immersed himself in it, and immediately saw the medicines inside.

Zhang Sanjia was the last martial arts champion of the previous dynasty. To be the champion, one must be both civil and military.

Although he claimed to be a military man in front of Zhang Zhiwei, his cultural level might be higher than Zhang Zhiwei's. If asked to recite poems or compose couplets, he could do it with ease.

When he was the top military scholar, the previous dynasty was carrying out the Westernization Movement. He also learned some foreign languages. Although he was not proficient in them, he could understand some words.

The packaging of this batch of medicines is all written in foreign languages.

There are boric acid solutions and high-purity alcohol, which are both very good wound disinfectants. They are much more effective than the inefficient disinfectants commonly used now.

There are also gelatin sponges for hemostasis and wound treatment, as well as sterile gauze containing iodine, which are good things that can prevent wound infection and inhibit bacterial growth, as well as some analgesics and anesthetics.

……

It can be said that he had all the medicines he was familiar with, and in quite large quantities, but there were some medicines that he didn't quite understand, such as penicillin, quinine, aspirin, tetanus toxoid and so on.

As a martial arts champion, Zhang Sanjia was not stupid. He immediately realized that this was a new foreign medicine and asked about its effects.

Zhang Zhiwei explained to him: "Quinine is a special medicine for treating malaria. I prepared some for you. Maybe it will be useful in the future."

"Aspirin is used to relieve mild to moderate pain, reduce fever, and it has other uses."

"As for tetanus toxoid, it is a serum that is used after an injury to prevent tetanus."

When Zhang Sanjia heard this, he was overjoyed. Open wounds like gunshot wounds are particularly prone to causing tetanus, and the mortality rate of tetanus is as high as 80 to 90 percent. If this thing can prevent tetanus, that would be great.

"Where is the penicillin?" asked Zhang Sanjia.

"This is a new drug that has not yet been launched on the market. I asked someone to take it out from the laboratory. It can be used to kill and inhibit bacteria, prevent and treat infections, and can also be used to treat various inflammations. In short, it has a wide range of applications," said Zhang Zhiwei.

"Are the things taken out of the laboratory guaranteed?" Zhang Sanjia didn't distrust Zhang Zhiwei, he just didn't trust the foreigners and was worried that they were doing experiments.

Zhang Zhiwei said: "Don't worry, the things I took out are safe. As for its effectiveness, it can not only prevent infection, but even if it is infected, the mortality rate will be reduced several times."

"This thing is the most precious among this batch of conventional medicines. Once you use it, you will know how precious it is. However, the current production is very low and it is very troublesome to make. Use it sparingly."

Antibiotics are somewhat similar to the settings in some fantasy novels, the older they are, the more powerful they are.

When antibiotics were first used clinically, a single injection of 2 units could cure serious infections, such as pneumococcal pneumonia.

But in later generations, for the treatment of Streptococcus pneumoniae, some patients needed to use third-generation cephalosporins or vancomycin at doses hundreds of times higher in order to be effective.

Zhang Sanjia nodded quickly: "I will pay attention."

Zhang Zhiwei continued, "In addition to these conventional medicines, there is also a batch of witchcraft medicine brought from Tengshan, which can quickly restore the current state at the cost of overdrawing the innate Qi. You and I are both practitioners, and we understand the pros and cons of this thing. Use it with caution. If you are giving it to ordinary people, remember to dilute it!"

Zhang Sanjia nodded repeatedly, and then bowed to Zhang Zhiwei:
"Little Heavenly Master, I, Zhang Sanjia, will never forget your kindness!"

Zhang Zhiwei grabbed him and said, "We are also a family. There is no need for us to be like this. I know you are in a hurry. Go ahead. I have to go to the next disaster relief site, so I won't see you off."

Zhang Sanjia stood up straight, took a step back, clasped his hands and bowed deeply, then turned around and left. His comrades were in a critical condition and he really couldn't delay, so he jumped up and flew out.

But after flying a short distance, he turned back and reminded Zhang Zhiwei that when he came, he noticed that a dike of Dongting Lake was about to burst. Once it broke, the disaster would be more serious and would affect more people.

After pointing out to Zhang Zhiwei the location of the dike that was about to burst, Zhang Sanjia turned and left. Although he really wanted to stay and help Zhang Zhiwei with disaster relief, human lives were at stake on the other side.

Previously, many of the conversations between Zhang Zhiwei and Zhang Sanjia were conducted in secret, while the reminder just now was a normal communication and everyone else heard it.

"Brother Zhang, another dike is about to burst, and the affected area is going to get bigger. Let's go and disperse the people in advance!" The little fat man from Yanwu Hall said hurriedly.

Although the disaster was extremely severe and affected a wide area, the authorities had been broadcasting to urge people to evacuate, but before the flood really came, not many people were willing to leave.

Because under your feet is the home where your ancestors have lived for generations. The house that provides shelter from the wind and rain, and the land on which you depend for survival, are all here.

If they leave here, they will be refugees. It will be extremely difficult to find a place to stay, and as for reclaiming the land again, that is unthinkable.

Land reclamation is definitely a heavy word in this year. It does not just mean taking a hoe and digging a piece of land. Even if it is land reclamation, the knowledge involved is very complicated.

It takes several years to turn a few acres of wasteland into fertile land for growing crops. What do you eat and drink during these years? And it takes even longer to build a house.

Therefore, no one wants to leave their homes unless it is absolutely necessary. Now the people in this land are all hoping that the flood will recede quickly like in previous years.

But the despair is that this flood is the worst in hundreds of years and will get worse, even lasting until next spring in some areas.

"Although the county town was flooded, some surrounding villages were not. Most of these villages are scattered, making it difficult to dredge the water," said Zhang Zhiwei.

"Yes, yes, that's right. Senior Brother Zhang is right. Besides, they will never give up their houses and land. It's impossible to force them to leave, right?" said a disciple of Jishidiang.

“Then what should we do? We can’t wait until the disaster happens before rescuing people.” said the fat man from Yanwutang.

"Then let's go get the source." Zhang Zhiwei said expressionlessly.

"Find out the source? Senior Brother Zhang... do you want to..." The little fat man looked at him in disbelief. This is a natural disaster, how can human power shake it? !

Zhang Zhiwei nodded and said, "Since the dike is about to burst, let's just prevent it from bursting."

"Brother Zhang, think twice. We just need to proceed with disaster relief step by step. Don't take any risks!"

"That's right, Senior Brother Zhang, you are so precious, how can you take such a risk?!"

"Besides, it's unrealistic for a few of us to block the breach!"

……

When these young people heard Zhang Zhiwei's bold idea, they hurriedly tried to dissuade him.

They have limited skills and narrow vision, like a frog in a well. They have no idea of ​​Zhang Zhiwei's real abilities. In their opinion, this is impossible.

Even though they had all heard that Zhang Zhiwei once cut the river with one finger at the foot of Wudang Mountain and saved the lives of a boatload of people.

But rumors are always exaggerated.

Many thoughtful people in the world believe that the truth of the matter is probably that Zhang Zhiwei cut off the huge waves with one finger, prevented the ship from capsizing, and saved the lives of everyone on the ship. As a result, the story became more and more outrageous.

Zhang Zhiwei ignored what his younger brothers thought and said:

"It's not a dangerous thing, just follow it."

After saying this, he thought about it and summoned a burst of black energy, which swept everyone towards the dike that Zhang Sanjia said was about to burst.

Riding on the wind and flying in the air, they soon approached the dike that was about to burst.

From a distance, the entire water surface was dim, and the turbid waves were hitting the embankment fiercely.

"Brother Zhang, the dam hasn't burst yet, we're not too late..."

The fat boy from Yanwu Hall hadn’t finished speaking yet.

There was a loud "boom" and an incredibly large and turbid wave rose up, like a waterfall rolling upstream, crashing heavily on the embankment, like thunder.

In an instant, the entire dike trembled, and many cracks appeared visible to the naked eye.

Water began to seep through the cracks, and then, like a domino effect, they collapsed suddenly.

"This, this, this... Senior Brother Zhang, look, there's something in the water... there's something in the water!"

The fat boy from Yanwu Hall looked down from the air and discovered that a huge dark blue tail could be vaguely seen in the turbid waves.

"I saw it too. It's as thick as a water tank. It was it that collapsed the dike!" said another person in horror.

They all saw it, and Zhang Zhiwei naturally saw it as well, and even saw it more clearly than them.

It was a huge blue-black python, which used the power of the flood to break through the dike.

Then, it rushed out from the hole with huge waves. The raging torrent rolled up wild waves, lashing everything with a rumbling sound, and large areas of indigo in front were painted by the dim flood.

And behind the flood peak, a huge snake head suddenly appeared.

"The big snake is causing floods, it's a dragon...snake is causing floods!" the little fat man shouted.

The others also turned pale. They came here to fight the flood and provide disaster relief, but they had encountered something like this.

A snake turning into a dragon generally refers to a large snake that has obtained Qi. After reaching a certain level, it will further transform into a dragon.

But this transformation requires an opportunity, which is when there is a flood.

At that time, the originally stable water veins will be separated from the earth veins, and new water vein branches will be born.

They can take advantage of the power of the flood, carrying the branches of the water veins all the way into lakes, rivers, and even the sea.

And in the process, they will absorb the power of the water veins.

If enough is absorbed, it can transform into a dragon, which is called the snake walking on a dragon.

If a snake or a dragon wants to move, it can't just follow a river and flow downstream. It has to follow the direction of the water flow, right?
The original river course and water veins of the river are stable and will not change even if there is a flood.

Snakes and dragons can only take waterways that did not exist before and absorb the newly formed water veins.

Therefore, throughout history, every time there has been a major flood, when the flood receded, there have been people who would see long gullies in the waterways. These were the traces of snakes and dragons.

If the big snake has to take waterways and water veins that didn't exist before, that means the flood will be diverted, causing a flood that will inevitably submerge villages and houses.

To avoid this situation, some skilled old Taoist priests would hang a Feng Shui sword under some bridges.

This magic sword cannot be used to cast spells, nor can it be used to fight magic, and it cannot hurt the snake.

It is used to determine Feng Shui.

And water veins, after all, are also a kind of feng shui.

Unless it is a huge wave with rich water energy, in most cases it will be cut off as long as it passes under this sword.

Once the water veins are cut off, the process of the snake transforming into a dragon will also be cut off.

When a snake transforms into a dragon, the big snake will merge with the water veins. If the water veins are cut off, the big snake will also be seriously injured.

Therefore, the sword is also called the Dragon Slaying Sword. (End of this chapter)
