Picric acid, also known as 246 trinitrophenol, yellow explosive, light yellow crystalline solid, odorless, bitter, characterized by the explosion of the core temperature of up to 1,000 degrees, enough to ignite the steel, the flame formed by the explosion will be scattered like gasoline on fire, even in the water can continue to burn for a period of time, the disadvantage is that the explosive instability, a little carelessness may cause a catastrophic explosion.

Zhu Jianjian is a crosser, of course, he knows the solution, and he paints and waxes on the inner wall of the cannonball, which solves the instability of picric acid that is easy to react with metals, but the picric acid, which has a stronger explosive power than TNT explosives, is still in trial production.

Although Zhu Jian has a golden finger and knows that picric acid is simple to make, but mathematics, physics and chemistry are his weaknesses, he doesn't know the chemical equation, let alone the specific operation method, only knows the story of an Englishman named Wolf who used concentrated sulfuric acid and concentrated nitric acid to treat stupid phenol and inadvertently obtained picric acid.

Knowing the great power of the picric acid explosion, Zhu Jian repeatedly reminded the elites in the laboratory to be careful, it was best not to touch the metal of this thing, let alone hammer or anything, once it exploded, the entire laboratory would have to be reduced to ashes.

The current Ming Empire is in the key to the replacement of the old and the new, all kinds of talents are in short supply, although they have begun to carry out all kinds of professional training, but they have not yet grown up, and the current elite talents are one less than one, so they have to be carefully protected.

Zhu Jian originally planned to accompany a group of elites to dinner in the scientific research institute and encourage them, but Wang Chengen whispered that Shanxi Guan Ruoguan was here.

Guan Ruoxi, who has close ties with the official, has countless assets under the full support of the Red Gang, and is now the richest man in Shanxi, the first female wealthy businessman in the Ming Dynasty, and all kinds of rumors about her are no less than Qin Liangyu, the only female god of war in the Ming Dynasty, with countless fans, and there are many people who come to propose marriage like a carp crossing the river, everyone knows that this Guan rich man is not only young, but also beautiful, the most important thing is that he makes too much money, who can marry her, the family is equivalent to having a gold mine that can never be dug up, both people and money, who doesn't want to? As for her widowhood, she has long been ignored. However, few people know that this domineering female president who can make money is actually just a super working girl, and the real big boss is Emperor Chongzhen, who is hiding behind the scenes and commanding remotely.

For a long time, Zhu Jian and Guan Ruozhi have maintained correspondence, in addition to talking about serious things, the basic conversation in the letter is also the short of the parents, and then there are some ambiguous content that makes people blush and heartbeat, it is not an exaggeration to say that they are flirting and scolding in the air, in short, the two are too familiar to be more familiar, because of the distance, only the last layer of tissue paper has not been pierced, and now, Guan Ruozhi's is here, it depends on Zhu Jian's attitude.

Zhu Jian slapped his ass and left without thinking about it, and went straight to Guan Ruozhi's Xiangju, which Zhu Jian secretly purchased for her in Jingshi City, and now it just came in handy, Guan Ruozhi secretly returned to Jingshi, she didn't go home, she just didn't want people to know her whereabouts, or rather, she didn't want to be discovered about her indescribable relationship with the Son of Heaven.

Zhu Jian went out of the palace in civilian clothes, and the accompanying guards were all in civilian clothes, Wang Chengen first sent a team of guards to Guan Ruozhi's Xiangju to search carefully, first confirm the safety, and after arriving at the Xiangju, he brought the two little eunuchs who accompanied him into the bedroom and searched carefully.

"Your Majesty, Mrs. Guan is bathing inside."

Wang Chengen whispered after withdrawing, he was familiar with the character of the Son of Heaven, he naturally knew what would happen next, he was entangled in whether to keep a file about this matter, once the file was recorded, it would be known by Queen Zhou and Queen Yi'an, if it was a little lady from a good family, it would be no trouble, at most she would be accepted into the palace and canonized as a concubine or something, but Guan Ruozhi's identity was a little sensitive, and this matter was a bit of a headache.

Zhu Jian didn't hesitate, pushed the door into the room, and took a bath at this time, the meaning is obvious, this is the temptation to eat fruits, it depends on whether you dare or not?

What happened inside, no one knew, Guan Ruo's personal maid Xiang'er came out of it with a red face, closed the door, and bent down to salute Wang Chengen.

Wang Chengen cupped his fists in return, nodded, Xiang'er comprehended, and stood outside the door with him, waiting for the summons, with a look of shame on his face.

Any eunuch, in addition to practicing extraordinary eyes, exquisite thoughts, there is also one of the most basic skills is standing skills, although Wang Chengen is old, but standing skills are absolutely first-class, standing still for a few hours is a small meaning, during this period you have to keep your ears up to listen, in case a day to call, you have to respond in time at the first time, and ear power is also important.

Wang Chengen's ear power is also very good, what kind of movement and sound coming from the room can almost be heard clearly, and he doesn't know how long it has been, he looked up at the sky and frowned.

It's winter now, it's getting dark fast, and it is estimated that in a while, the city gate and the palace gate will be closed, but the movement and sound inside have not stopped, and the emperor doesn't want to return to the palace?

When he was struggling with whether to remind the emperor to take care of the dragon's body, Guan Ruo's lazy call came from inside, "Xiang'er......"

Xiang'er hurriedly responded, her pretty face turned red, pushed the door in, and Wang Chengen could only stand and continue to wait.

After a while, Xiang'er, whose pretty face was full of shy red clouds, came out and gave Wang Chengen a blessing, "The emperor is already asleep." ”

Wang Chengen nodded and smiled bitterly, stretched out his hand to summon a little eunuch, and gave a low command, and the little eunuch took the order and left in a hurry.

Half a pillar of incense, the little eunuch came back sweating profusely, and a large group of biao-shaped men with guns and swords quietly appeared inside and outside the Xiangju, and even there were people lying on the roof with guns, guarding the entire Xiangju so that not even a fly could fly in.

When the sky was about to brighten, Zhu Jian's guards quietly slipped out of the Xiangju and returned to the palace through the side door, preparing to preside over the early dynasty.

Emperor Chongzhen often goes out of the palace in micro-clothes, observing the people's feelings, which is a manifestation of love for the people, which is normal, but staying outside and not returning to the palace, and for three days, it is very abnormal, no need to guess that the emperor has a woman outside.

"Princess, tell the palace about that woman." Queen Zhou said with a pretty face, she actually knew about this, and knew that Guan Ruoxi's identity was detailed, and she was a little resentful in her heart, so many young and beautiful good families in the palace, who do you want to let go to bed, but want to provoke a widow? But with a gentle temperament, she didn't dare to make the emperor unhappy, so she could only spill her anger on Wang Chengen.

Wang Chengen faced the scrutiny of Empress Yi'an, Empress Zhou, and Tian Guifei, cold sweat on his forehead, he felt that he was the Ming version of Sister Dou'e, as much as he wanted, he dared to care about the emperor's sister? Give him a hundred leopards and don't dare.

"Go down, this is the ...... Let's keep it on file. ”

Queen Zhou saw that he was frightened, her heart softened, and waved him to retreat, if she was going to get pregnant, after all, it was the dragon species of the heavenly family, or keep the file, as for the name, that is a matter of the future, let's talk about it then, anyway, Guan Ruozhi has already set off for Shanxi, and the emperor will no longer stay outside.

She is in charge of the small treasury of the Son of Heaven, knows that a lot of income comes from Guan Ruozhi, and also knows that the Son of Heaven often worries about money, it is indeed not easy for a woman to do this, at least she is sincere to the Son of Heaven, in fact, she sometimes envies Guan Ruozhi and Lu Hongniang, one helps the Son of Heaven lead the troops to fight, and the other helps the Son of Heaven to make money desperately, but she can only keep a small account, and she can't help at all, and she feels a little guilty.

Empress Yi'an's expression was calm, after all, this was the family affair of the uncle emperor, and Empress Zhou was so generous, she was even more embarrassed to meddle as a sister-in-law, and she didn't know how to deal with this matter if she left it.

Tian Guifei's face was resentful, the harem of the Son of Heaven was also Queen Zhou, a red concubine and her, the red concubine led the troops to fight at the border all the year round, it was difficult to see each other, and she was the most favored, but now, the emperor has a new love, she is afraid of falling out of favor, so she instigated the two queens to ask for the guilt, but unfortunately Queen Zhou is generous, and she has no choice.

Seeing Queen Zhou's eyes, the resentment on Tian Guifei's face became even stronger, it's not that she doesn't work hard, all the tricks have been used, this field is about to be plowed, but the melon is not planted.
