Not long after Jiang Yao was summoned by the big medicine owner, a news spread out of the county magistrate's office, shocking the entire Yong City.

Ye Tianhen, the great medicine master, officially appointed Jiang Yao as the small medicine master and was promoted to the master of Chinese medicine!

Not to mention this, the big medicine owner also ordered that from now on, the small medicine owner Jiang Yao will take charge of the disaster relief and anti-drug strategy, and have full authority to dispatch the doctors, troops, and materials involved in the disaster relief!

It is tantamount to saying that the important matter of fighting against viruses and epidemics will be entrusted to the small medicine master Jiang Yao.

Jiang Yao suddenly gained great power and became the core figure in commanding disaster relief.

The entire epidemic area has hundreds of thousands of troops and eight thousand doctors, all controlled by ginger medicine!

All the soldiers and civilians in the city also knew that in order to develop new medicines, the little drug owner turned into a gray-haired old man in just a few days, and everyone who saw him was moved.

They also heard that the little medicine owner’s merit book lit up five lamps overnight!

It can be seen that even the Lotus Deng Empress was moved by the virtue of the young medicine owner.

However, the poisonous epidemic is so dangerous, can the little medicine owner who takes over really turn the tide, quell the poisonous epidemic, and save the Baolian Kingdom?

Although many people want to believe it, they still dare not believe it.

Soon, all the gas masks invented by the small drug owners were distributed to doctors and soldiers on the front line of the anti-drug war.

As soon as 30,000 gas masks are issued, they will be effective immediately.

As long as you have a gas mask, your anti-virus ability is greatly increased and the infection rate is greatly reduced!

At this time, even a fool knows what the gas mask invented by the little drug owner means.

This means that as long as gas masks are widely promoted, the spread of the virus epidemic will be effectively curbed.

Not only can you buy valuable time, but you can also kill poisonous insects more effectively.

Because of this gas mask, everyone’s confidence and fighting spirit were ignited again!

Coincidentally, on the third day after the distribution of gas masks, a large-scale wave of poisonous insects struck again.

All kinds of poisonous insects, carrying poisonous diseases, are surging in overwhelmingly.

The second, larger and more brutal defense battle of Yong City began.

Jiang Yao handed over the defense of the city to Cui Wei and other Eight Immortals, and stepped up his own efforts to build a simple generator.

He found a magnet, had gold drawn into threads, made into wires, and then painted with paint as an insulating layer.

Gold in this world is not currency, but jewelry and high-end tableware. It is not difficult to find. If there is no copper wire or iron wire, we can only use gold wire instead.

Of course, gold wire actually conducts electricity much better than copper wire.

Finally, a large brush was made.

These are all due to the physics education Jiang Yao received in China.

Making a generator with your own hands is also one of the experiments in physics class.

However, in a classical ecological environment, the difficulty is different when using native materials to make a generator without any modern materials.

Jiang Yao spent five full days of work and finally, with the help of a group of sergeants, made five hand-cranked small generators.

Just do a simple experiment and you can generate electricity!

"Send the order, molten salt!" As soon as the original generator was completed, Jiang Yao ordered the second step.

Use an iron-making boiler to melt salt!

That is to say, the salt is converted from solid form to liquid form as electrolyte.

The melting point of salt, Jiang Yao remembers, is about 800 degrees Celsius. The temperature of iron-making furnaces in this world has exceeded a thousand degrees, so there is no problem at all.

Jiang Yao gave an order, and the salt that had been prepared long ago was sent to the boiler and smelted over high fire using a blower.

In less than half an hour, the temperature of the furnace was already very high, definitely over 800 degrees. The salt in the boiler was smelted into liquid salt (not salt water, but liquid salt. Salt water does not work)

Finally, Jiang Yao asked people to shake the handle and insert both ends of the wire into the hot boiler.

The melting point of gold is more than a thousand degrees, and the wire will not melt for a while, so the electrolysis reaction finally begins.

White metal particles soon appeared.

At the same time, streams of pungent gas (chlorine gas) volatilized and were discharged through the pipe prepared by ginger medicine, while the firewood pile was burning at the mouth of the pipe.

Chlorine is highly toxic and has stronger oxidizing and combustion-supporting effects than oxygen. When highly toxic chlorine comes into contact with burning firewood, it takes away the combustion-supporting role of oxygen and participates in the combustion of firewood to generate carbon tetrachloride.

As a result, the highly toxic chlorine gas was eliminated without causing any harm.

The cathode of the wire began to absorb a large amount of white metal.

sodium!

The experiment successfully electrolyzed sodium!

Jiang Yao directed everyone to follow the same method, and in just one day, thousands of kilograms of sodium were produced!

Sodium is a very reactive metal and can easily oxidize. In order to preserve the sodium, Ginger Medicine sealed it with wax oil and hid it in a porcelain bottle.

Outside, thanks to the effect of 30,000 gas masks, the attack of the insect tide was finally repelled again.

However, the number of people who have died from the epidemic in various places has exceeded 500,000!

The corpses could not be disposed of, and there was not enough potion to soak the corpses. As a result, many corpses quickly rotted and turned into more poisonous insects.

A new round of large-scale virus epidemic is brewing.

"Time! What we lack most is time!"

Jiang Yao, who had already moved into the county government office, told everyone, "As long as we control the spread of the virus within half a month and wait until new gas masks and new drugs arrive, we will be able to take the initiative!"

………

On the fifth day after the insect tide receded, amid Jiang Yao and everyone's anxiety, four items, including armadillo sheep urine, cryptohorn worms, flint nest stones, and white bone marrow, finally arrived in sufficient quantities!

In order to collect these four items in sufficient quantity within ten days, Gu Qinghuan not only mobilized 20,000 soldiers and horses, but also mobilized hundreds of thousands of civilians.

Ginger Yao asked for a thousand kilograms of each item, but in fact everything exceeded a thousand kilograms, and it was overfulfilled.

"Everything is ready, let's start refining the new medicine!"

Jiang Yao immediately invited the Eight Immortals, and with a gesture of good wine and meat, he cupped his fists and said:

"Seniors, you have worked hard to defend the city these days, and your merit books are all lit up. Now all five medicines are ready, except for the most important immortal blood."

"I need at least a hundred kilograms of blood. Including Xiao Hei and I, there are exactly ten people. Each person will give out ten kilograms of blood..."

What? Ten pounds of blood per person?

How much blood can one person have?

The blood of strong men like Pan Zhen and Cui Wei only costs about ten kilograms. The blood of a slim woman like Li Xixia only costs about eight kilograms.

Your ginger medicine will make us lose ten pounds of blood at once. Isn’t that fatal?

Even death is not enough.

I'm afraid only Xiaohei, a big black dog weighing more than 200 pounds, can produce ten pounds of blood.

Jiang Yao looked at everyone's expressions and quickly explained: "Well, it's not ten pounds of blood at one time, but two times. Five pounds at a time. You are all immortals, there must be no problem."

"Ten days later, when you guys have recovered, I'll give you five more pounds."

"Okay, I'll go out!" Cui Wei was the first to support, "Five pounds is five pounds, and you won't fall."

If a real mortal were to bleed like this once, they would be seeking death. But for them, it is not difficult.

Li Xixia gritted her teeth and said, "My blood is only eight jins, and it's only five jins!"

At that moment, everyone raised their knives and started bleeding from their wrists.

Immortals are immortals after all. Real mortals would not dare to do such a large-scale bloodletting.

Jiang Yao had already prepared a wooden barrel to hold the blood.

He himself also cut his wrists, and blood flowed out like a spring.

After five kilograms of blood was drained, Jiang Yao's face was as white as paper and his eyes were black. Set off by his pale hair, he looked like a corpse in a tomb.

He is not an immortal. Once five pounds of blood is drained, he will become even weaker.

After five kilograms of blood was released from the Eight Immortals, their faces were all pale, especially the four fairies, including Li Xixia and Luo Lingxi, who looked as horrifying as corpses.

However, Jiang Yao was in the worst condition. After all, his cultivation level was not even that of Mahayana.

Finally, Xiao Hei also injected five pounds of dog blood.

It has a lot of dog blood. Although it makes its limbs weak from the five pounds of dog blood, it can completely bear it.

"Jiang Yao, can you prepare new medicine in this state?" Li Xixia asked worriedly.

After she said this, her feet felt a little weak.

Jiang Yao stood up tremblingly, already looking like an old man. He was five pounds of blood, and even his originally straight back was a little rickety.

Everyone sighed when they saw him like this.

Originally, Jiang Yao was the youngest one, still a teenager. But now, he looks like the oldest one, like a big brother to everyone.
