Time Travel: I am the idle king Li Shen and Li Shimin in the Tang Dynasty

"all fake?"

It's really unbelievable that the things they believed with great difficulty suddenly became false.

"Then...what about those methods of yours?" Li Chengqian asked.

"Of course the methods are also fake. The evil ghosts appearing, beheading evil ghosts, and frying evil ghosts are all fake."

Li Shen said truthfully.

"Then what kind of deception did you use?" Li Shimin was extremely curious after hearing this.

Li Shen came to the table, picked up a piece of yellow paper, and tapped it with the incense stick. Immediately, a mark of an evil spirit appeared on the yellow paper.

Li Shen held the yellow paper and explained to everyone:

"Aye, I drew this evil ghost beforehand. I used ordinary paper, dissolved saltpeter in water, and then used a brush dipped in the saltpeter water to draw the evil ghost on the yellow paper.

In fact, you can draw whatever you want. People may draw some animals or something and say it is a monster.

When the water dries, there will be no trace on the paper, but saltpeter is flammable, and when you touch it with the incense stick, the saltpeter will produce a dark flame, forming the shape you just drew.

Li Shimin walked over and took it. Since Li Shen said it was fake, he was not afraid anymore.

After taking a closer look and smelling it, there is indeed a familiar smell.

He already had the formula for gunpowder, and of course he also had some of those grenades.

"Yes, that's true. Then why can a sword be used to chop the evil ghosts to make them bleed?" Li Shimin put down the yellow paper and asked again.

Li Shen put the yellow paper on the table.

"Aye, this is a bit more troublesome. I went to Daji Temple and burned some straw, and then filtered out the water, which I call alkaline water.

Moisten the yellow paper with alkaline water, and after it dries, no abnormalities will be visible on the surface.

Then use this one.”

Li Shen picked up the gourd on the table.

"What's in here?"

"Aye, this is filled with turmeric water. Once you mix this turmeric water with alkaline water, it will turn red.

So the blood you thought was left after I killed the evil spirit was actually just a transformation.

Even if there really are ghosts, they have all left their bodies, so where would the blood come from?"

After Li Shen finished speaking, he opened the gourd, poured a little water on his fingers, and lightly drew on the yellow paper on the table.

A red line suddenly appeared on it, as if a wound was bleeding.

When Li Shimin saw this, he also took the gourd and poured a little on his finger and lightly drew it. Sure enough, the result was the same as Li Shen's.

"Is it so magical?" Li Chengqian also came forward, and Li Shen simply poured the turmeric water in the gourd into the bowl.

Let them play slowly with the brush.

He got several sheets of this treated paper.

Several people took pens and drew a few strokes on the paper. Li Shimin tried it with his sword and it was exactly the same.

"Tenth brother is indeed a talented person." Li Chengqian exclaimed as he looked at the evil ghost in front of him that he had killed several times.

"Haha, yes, Shen'er has been smart since he was young." Empress Changsun smiled happily.

"Then what happened to your hand when you put it in the oil pan? I saw it clearly, it was already boiling hot, so why was your hand fine?

Isn't that oil?" Li Shimin asked again.

Others were also very curious.

This is as curious as uncovering the truth about magic.

“Aye, mother, it is indeed oil.

Stones start fires. "

Li Shen turned around and gave an order before continuing:

"This oil is indeed oil, but it's not just oil, there's something underneath."

"Is there anything else?" Upon hearing this, Li Shimin leaned over to look into the pot, but after looking for a long time he couldn't see what was in the pot.

All you can see is the oil in the wok gradually starting to boil.

At this time, Shitou put his finger into the oil pan and said to Li Shen:

"My Lord, it's almost done."

This action surprised everyone. They actually used their fingers to test the temperature. Moreover, the oil pan had already started to boil, so how could it not be hot?

After hearing this, Li Shen reached his hand in and slid it twice. The oil pan began to boil and roll continuously.

"This..." Everyone was a little surprised and looked at Li Shen, waiting for Li Shen's explanation.

Li Shen pulled his hand back, washed it again, and then said:

"Aye, there is vinegar under the oil."

"Jealous?" Li Shimin didn't react.

"Your Highness Prince Ji, are you talking about the jealousy?" Wang De asked tentatively.

"Yes, it's the jealous one.

Put the vinegar in the pot first, then the oil. The oil is darker in color, so you can't see the vinegar underneath.

Vinegar and oil are two different things and will not mix together.

Vinegar heats quickly and produces bubbles before the oil has time to heat up.

When ordinary people see this, they think that the oil is hot and starting to boil, but in fact, the oil is just warm at this time.

If you don’t believe me, you can try it.”

Li Shen tried his best to explain the principles in a simple and easy-to-understand way so that everyone could understand.

In fact, it’s just that the boiling points of oil and vinegar are different. I learned this principle in school.

After hearing this, Li Shimin took a step forward, wanting to give it a try.

"Father, let me go first." The prince came over quickly, gritted his teeth, and put his finger into the boiling oil pan.

"Hmm?" Li Chengqian originally thought that even if it wasn't scalding, it would be very hot.

But now when he put his hand in, it was only slightly warm.

He also stirred it twice with his fingers.

"Father, it is just as my tenth brother said, the oil is not hot at all." Li Chengqian reported.

"Really? Let me try."

Since both sons have tried it, there is nothing to worry about.

Li Shimin also put his finger in and felt the same as Li Chengqian.

Even Empress Changsun and Concubine Wei tried it out of curiosity.

"Okay, everyone, leave." After the puzzles were solved, Li Shimin waved his hand, and Wang De immediately asked the eunuchs to take all the things away.

The hall set up by Li Shen was also withdrawn.

Several people returned to their seats, feeling somewhat sad.

So many people were deceived by a naughty twenty-year-old son.

"Tenth brother, how did you come up with these methods? To be honest, even if they are not immortal arts, they are still amazing."

Li Chengqian sighed.

"Brother, you are too kind. They are just some small tricks. In fact, those evil monks who pretend to be gods and ghosts in the folk that you just mentioned also use these methods.

The common people were amazed by their beauty and thought they were real immortals. "

Li Shen replied.

"Shen'er is indeed a talented person and extremely intelligent." Empress Changsun praised with a smile.

But Li Shimin snorted:

"Hmph, what's the use of having talent? It's just that you haven't used it in the right way.

With such wonderful means, he actually used it to cheat and deceive people, and even wanted to defraud my money.

If I hadn't been alert, I'm afraid he would have succeeded again today.

You also say that gold overcomes wood and you want to remove gold. I think it is you who overcomes me. "

Li Shimin felt angry when he thought about how Li Shen had just deceived him, pretending to be an immortal and talking nonsense in a serious manner.

He believed that the Taiji Palace was too yin and that wood produced fire, which led to the prosperity of yang.
