Two men carefully held the wooden box, walked to a room, and before they could open the door, they heard a rapid cough from inside. Pen ~ fun ~ pavilion www.biquge.info

The man holding the wooden box sighed, knowing that it was the coughing sound of the gentleman, and he was inevitably a little worried.

Pushing the door in, he took a cup of tea and brought it to the gentleman, who took it with his rough, yellowish-black fingernails that had been half corroded.

The two disciples were already familiar with the appearance of the gentleman and still respected him, but if it was the first time he saw him, he was only afraid that he would be startled.

This person looked extremely old, his teeth seemed to have been lost, and his voice was extremely hoarse, which was not normal aging, but damage caused by long-term exposure to various toxic substances.

Many of the calluses or spots on the fingers have also been damaged by something unknown. A little finger of the right hand was blown off, and it was blown up in an accident during the test.

At the age of 50, but with the pain of 70 years old, the lungs that have been injured by some toxic smoke and dust always cough, which sounds heart-wrenching.

The old man's surname is Mu, the orthodox old family of the Xia Kingdom, and he is also a gentleman respected by the two disciples, not the enlightened kind, but a real apprentice.

Even though the old man surnamed Mu was already so old and sick, the two students understood that their husband was incomparably stronger.

Knowledge is power, and it is also money. And when power and money are combined, they are naturally powerful.

Ten years ago, when a craftsman was producing delicate castings, he found that the castings were often stuck to the mold, and the two disciples' husbands only used a little limestone to grind into powder as the inner bottom of the mold, and when the molten metal juice was poured into it, it was heated and decomposed, and when it was disassembled, only some water was added to the casting to naturally separate, and even extremely fine things such as leaves and flowers could be melted and cast.

That's money.

A long time ago, a salt lake was discovered in the desert, and the old gentleman used some methods to dry the salt that can fertilize the fields, and sprinkled it into the fields to make the crops that were originally dry and yellow, the plants small, the greedy green and late ripening, and the brown spots grow strong, especially the yield of some vegetable fields and vineyards has increased a lot.

That's power.

Today, their husband has left his name on the temple of the Magi, and his finger in the gunpowder of the cannon, but he has not forgotten his ambition to guide these young people who are either admired or genuinely fond of this discipline to move forward.

Therefore, when the two disciples came in with the wooden box, the old gentleman's face showed a smile, and he felt that there must be something new to discover, and the disciples could not decide, this is a long time ago.

If you're lucky, it means that there may be another person who can be accepted as a disciple by him.

"What's the good?"

The sound came from the mouth with incomplete teeth, a little out of tune, but the disciples understood it, held the wooden box and put it on the table, and handed over a piece of paper.

The old gentleman lowered his head, looked at the content on it, and couldn't help but take a breath.

"It's an inseparable thing, pale yellow like wax in color, heavier than water. It is highly toxic and has the stench of garlic. ”

"When exposed to air, it will spontaneously burn, emitting a strong white smoke that can be absorbed by water, and the amount that is missing is yang energy."

"Reaction with hot concentrated caustic alkali will produce a fishy smell, this gas is also highly toxic, can burn in the air, and will emit a faint blue fire when observed at night."

"This thing can be extracted from bones, so the graveyard ghost fire is this fishy gas......"

"This thing can also be extracted from struvite stone, cattle and horses are herbivorous and have long bones, so it is speculated that this thing is an important reason why struvite can fertilize the field......"

There is also a complete set of various verification methods drawn with a graphite pen below, and many details make the old man feel a sense of sudden enlightenment, and he can't help but admire the ingenuity of some verification methods.

In particular, two experimental methods are proposed, one is called control, and the other is called contrast, which is extremely logical, and the old man just glanced at it and understood what it meant.

He has also used this method of contrast, but he has not come up with a formatted theory so systematically, and often ignores many things.

Thinking of the word highly toxic written on the paper, the old gentleman actually had a sense of bosom friend, he was also exposed to many highly toxic things when he was young, and it was not easy to survive by luck.

A simple piece of paper, the words on it seemed to the old man that he had exchanged his life for it.

After a long time, the old man carefully put away the paper, and reflexively looked at the wooden box on the table and the glass bottle in the box.

"Sir...... Do you think it's true? ”

The old man shook his head and said, "It doesn't matter if it's true or not, even if it's fake, this piece of paper alone is enough to prove that this person is ahead of you, or even me!" ”

The two disciples were startled, and looked at the paper that had been put away by the gentleman in disbelief, not knowing what magic power it could make the gentleman who was respected by them so praised.

It was understandable to walk in front of them, but they really couldn't believe that they had walked in front of Mr., let alone just a piece of paper with some words written and some drawings drawn.

The old man picked up the small bottle, carefully observed the note with the word poison on it, and couldn't help laughing, the little skeleton was very cute and intuitive, and it was more direct to see what it was when it was put in a glass bottle.

If everything written on that piece of paper is true, if all those designed experiments can be done, then this vial of seemingly ridiculous things can change a lot.

For example, the ghost fire in the cemetery, which has been difficult to explain until now, can finally be explained by theories such as not ghosts.

For example, it is still clear that struvite can fertilize fields, but what exactly is in struvite has not been found in fertile fields, and controlled experiments designed above can find out. Once it is found, it is not struvite that fertilizes the field, but struvite in struvite, and other ores can be used instead of struvite to cope with the situation that struvite is becoming less and less and the land population is increasing.

Even if it can't be built now, it paves the way for future generations, like a compass, at least knowing where to go, it will save a lot of detours.

The old gentleman glanced at the contents of the paper again, and believed in his heart, and he felt that a person who could devise such an experiment would never make it up, because it was easy to see through what he had written.

As for why he didn't write how to prepare, the old gentleman also knew very well what was going on and didn't care.

"Go, go and call them all, and I'll show you what this thing is."

One disciple hurried out, while the other helped the old man to a place full of glass, ceramics, gold, silver, and other instruments. In the cabinet next to it, there are also stacks of electric stacks used hundreds of years ago, broken glassware, and many strange materials that have been separated.

The old gentleman recounted the contents of the paper with accurate memory, and the disciples skillfully got busy, and saw the strange and shocking scenes.

The solid, cut into small pieces taken from the water, burned itself in the air, emitting a thick white smoke; Buckled in a glass container in the mercury tank, the solid also burned, and a layer of white snowflake-like scales fell on the mercury, which disappeared in an instant when placed in the water; When heated with these white solids, the hot fire alkali produces a kind of fire that is exactly the same as the ghost fire described by those people when it is ignited; A dog was fed something as small as a grain of wheat and soon died......

Everything was the same as it was written on that piece of paper, except for the foul smell of garlic, which no one smelled.

The rest of the control and comparative experiments on crops will take too long and cannot be completed at this time, but the idea is clearly correct.

At this point, not only the old gentleman, but also those disciples believed what was on paper.

Everyone looked at Mr. in unison, and finally someone said what they should have said.

"Sir, if all this is true, then...... So this person can engrave his name into the temple of the Wise Man? ”

The old gentleman nodded and said, "Yes, it is possible, at least it is enough for me." Who sent this? ”

"The address is written on it, and it is in an inn in the capital."

"Go find that person and invite that person here. Just go! ”

The disciples left in a hurry, and according to the address above, they quickly found the inn.

In the inn, the people are not there.

The innkeeper recalled for a moment and said, "The man went out for a stroll and would not be back until evening." ”

"How old is that guy?"

"Seventeen or eighteen? A Mincheng accent, as if he was here to take the exam. ”

"Seventeen or eighteen?"

The questioner was stunned for a long time, unable to believe that this was true, but the innkeeper said with great confidence: "You will never be wrong. ”

The two men asked for a pot of tea and waited there, talking quietly about what seemed to them to be inconceivable.

Until dark, Zhang Xuan came back with some snacks from the capital, and as soon as he entered the door, he heard the innkeeper shouting: "This little gentleman, someone is waiting for you." ”

The two people who had been waiting for a long time hurriedly got up, Zhang Xuan was also startled, and said that he had just come to the capital, and he was just going to listen to the chatter of a few young people, could it be that he had committed a crime?

Looking at the anxious expressions of those two people, and the careful gaze that looked at him as if he was interrogating, Zhang Xuan was even more shocked in his heart, swallowed his saliva, and said with a smile: "What are you looking for me?" Didn't you find the wrong one? I'm just from Mincheng......"

One person directly took out a wooden box and asked, "Is this yours?" ”

Zhang Xuan breathed a sigh of relief and said, "It's not mine." My friend asked me to send it here. Don't know what's going on? ”

"Good thing. How old is your friend? ”

"As old as me, nineteen."

"Nineteen?"

The two of them looked at each other, completely froze, and kept shaking their heads, unable to believe that this was true...... How can it be only nineteen?
