"Kill him? Let him go! Kill him? Let him go...... "Hong Tao is indeed a little uncomfortable, not physically but mentally.

Just made a neat Gao Yu, this is another Tong Guan, it is worth it to attract the life of traitorous ministers, and there are only a few big villains in the Northern Song Dynasty, who are changing tricks to get to their side.

If you get it all together, it's easy to do, and after an avalanche, the world will really be peaceful. But they seem to be deliberately looking for trouble, coming one by one, and playing wheel tactics with themselves.

What should I do with Tong Guan? It's a more urgent matter than complaining about the heavens. It's too risky to kill him, it's not necessarily worth it, and it's too good to keep him.

Wang Zhongzheng is not a person who understands too well, and with a very bad talent Tong Guan by his side, I am afraid that his life in Huangzhou will not be easy in the future.

"Damn! It's a disaster that lives for thousands of years, and God will help you. Come on, Lao Tzu can't kill you, and he can't make you comfortable! Lian'er, tomorrow you will go back to Huangzhou City and bring a letter to Wang Si for the officials. ”

In fact, Hong Tao's heart is still very wide, and when he was not sure whether to kill or release, he didn't think about it anymore, but began to be lazy again.

found a copper coin and spun it on the table, if it ends up facing up, tonight will be Tong Guan's death; If it's back up, let him go.

Well, back up! Tong Guan was able to survive thanks to the fact that the center of gravity of this copper coin was biased towards the front, and sometimes life is so coincidental.

But who is Hong Tao, be careful with your eyes and no face, no skin, and no skin. said that he had let Tong Guan go, and he really didn't plan to kill him immediately, but in his heart, he began to think about how to fool God and rely on the fate of this copper coin.

To say that Hong Tao's ways to harm people are no less than the ways to benefit mankind, maybe even more. Let him think of a chemical formula for several days and couldn't understand it, but when it comes to pit people, he only frowns and has a way in less than a quarter of an hour.

"Don't go back to Huangzhou, where the official goes, the concubine will follow and serve the official, this is what the eldest princess ordered......" Lian'er didn't pay attention to Hong Tao's muttering and throwing copper coins after entering the house, how strange this husband is, sometimes it's no different from a nervous disorder.

But as soon as he said that he wanted her to go back to Huangzhou City alone, he immediately put down his pen and pouted in protest. There is nothing to play in Mawei City, and there are no delicious snacks, but if there are no officials in Huangzhou City, wouldn't it be even more boring.

"Nonsense, this official is going to go on the expedition soon, have you heard that the general still takes the lady with him? If the official family knows about it, I'm afraid there will be no hope for your fate in this life! ”

In comparison, Lian'er is an official fan in the Horse Mansion. She had been secretly inquiring about how the edict should be canonized, and then she was secretly working in that direction. And she didn't mention it to anyone, of course, she didn't say anything when she was reviewing her homework.

“…… The official doesn't need to bring a letter to Wang Si, just tell the concubine. Lian'er felt that the pony had a point, and her mouth was still pursed, but she no longer dwelled on the questions that had been left behind.

"Go get the milk, the official will write it himself." With a message? It's not that Hong Tao doesn't trust Lian'er, but he's afraid that she won't be able to say it clearly. The fewer people who know about this matter, the better, and once you leak it, you can't explain it.

“…… Oh, the slaves get it! As soon as she heard that she was going to write with milk, Lian'er immediately withdrew the pig's mouth.

I ran to the door and plugged in the wooden bolt, then went to close the curtains, and then lit the gas lamp, and then took out a round-bellied glass bottle from the cabinet, which contained a small half bottle of yak milk.

And that's not all, the bottle of milk was not drunk, but poured into a small dish, and then handed a soaked but unused brush to him, and then walked back to his seat, with the back of his head facing this side.

What is the use of milk and brushes? Can these two things come together? The answer was soon revealed. Hong Tao picked up a brush and dipped it in milk, and began to write on the white paper by the light of the gas lamp. Traces can still be seen when the milk is wet, but as it dries, the front handwriting gradually disappears.

"This ordinary official document written on the flower room, don't hand it over to Wang Si in person, and you don't need to seal the wax separately, just find a messenger to hand it over." After writing three pieces of paper in a row, Hong Tao stopped his pen and put the last half of the handwriting close to his mouth, blowing while instructing Lian'er.

Now I understand, Hong Tao is using milk as invisible ink to write secret letters. Simple commands can be passed through mathematical formulas, but statements that are too long and complex can be cumbersome.

How can you keep your communications private in a simple and effective way? This problem was originally pinned on chemistry, but Hong Tao experimented for a long time, and the only thing he knew was that sodium nitrite, the material used as invisible ink, could be made, but the developer potassium iodide didn't know what to do, so he could only give up halfway.

Since you can't play the high-level ones, let's go to the low-level ones. There are also many things in daily life that can be used to make simple invisible potions, such as lemon juice and milk.

In the end, Hong Tao chose milk, because Huangzhou lacks everything, but there is no shortage of milk. The barren mountains and mountains are high-latitude areas, where to find lemons.

The usage of this thing is very simple, it is written with diluted milk, and after drying, the handwriting is almost invisible. The development does not require chemicals, just put it next to the gas lamp and bake it to show the font.

Its practical light sulfuric acid solution is written on white paper, and there will be no traces after drying. The developer uses litmus reagent, and the font will turn red when it encounters acid.

It's just that sulfuric acid is too oxidizing and easy to fail after a long time. Once it is exposed to moisture or certain substances during transportation, it may also react, but it is not as reliable as milk.

What did Hong Tao write on the secret letter? Will Wang Si, who is in charge of supervising the production of flower paste in the flower house outside Huangzhou City, have a relationship with Tong Guan? If you don't say that Hong Tao is a professional pit man, his trick is called dead and alive!

In the letter, he told Wang Si to secretly add some ingredients to the can, and then find an opportunity for Tong Guan to eat. What's the ingredient? Of course, it's preservatives and lead powder, and the dosage is ...... Don't eat too much, don't eat it and it will attack within two days, and it's best to have symptoms after a few months.

What kind of dosage can achieve such an effect, Hong Tao said in the letter, find a few Xia captives who boil flower paste in the flower room to do in vivo experiments, one dose per person, delicious and delicious, and you will know how much dose is appropriate after a month or two.

As for how to accurately let Tong Guan eat poisonous canned food, he has to eat it many times in a row without being suspected, which requires Wang Si and the others to use their brains, if even this little thing needs to be spent by the officials themselves, wouldn't it seem that the children's league and the youth league are too wasteful.

Hong Tao also made it clear in the letter that if Tong Guan could not be allowed to take poison alone for a long time, the possibility of even Wang Zhongzheng being harmed could not be ruled out. Whoever asked him to take a big traitor as a staff member, and it is no wonder that others are unlucky together.
