The bright moon is slanting to the west, and the people in the scattered flower building go to the empty building, and the surroundings are quiet.

The fourth floor was a mess, the ground was full of holes, and all the long windows around it were destroyed, and the wind was ventilated on all sides. The night breeze whistled, and the moonlight shone in through the long, broken windows, shining on the dark holes in the floor and the mottled blood on the floor. If it weren't for these sights, it's hard to imagine a bloody and thrilling battle taking place here not long ago. Now, all of this has been settled with the killing of all eighteen Assassins.

After returning from the Scattered Flower Building, Wang Yuanben and his wives and concubines reported that they were safe, and they had to rest, and today's thrilling Battle of the Scattered Flower Building made Wang Yuan actually very scared and tired, so he was a little tired.

However, before going to sleep after washing, when Wang Yuan inadvertently checked the things sent by Zhao Qing and others from the Eight Tigers, Wang Yuan made a surprised discovery.

Since the day he saw Nie Jiangchuan using a poisonous phosphorus bomb in Beihai County last year, Wang Yuan has been extremely interested in how the poisonous phosphorus bomb is made. In the current era of the Tang Dynasty, Wang Yuan has never seen what gunpowder looks like. During the Chinese New Year, the Tang people actually replaced the common firecrackers in later generations with the crackling sound of bamboo tubes burning in bonfires, which shows that gunpowder is still a rarity in these years.

But after seeing Nie Jiangchuan use a poisonous phosphorus bomb, Wang Yuan was very puzzled. There was apparently gunpowder in the phosphorus bomb. Taking advantage of the flammable properties of phosphorus, coupled with the instantaneous small explosion caused by the collision during throwing, the combustion of poisonous phosphorus can be made without ignition. In the smoke of poisonous phosphorus, Wang Yuan could smell the familiar smell of gunpowder, which made Wang Yuan very interested.

At the beginning, a lot of poisonous phosphorus bombs were also found from Nie Jiangchuan, but Wang Yuan did not understand this knowledge, so he had no way to analyze their composition. In addition, he was in a bad situation and had many affairs, so he gradually put the matter down. During the attack on the city of Yang, after the construction of the Shenwei cannon, Wang Yuan sighed in his heart, if there was gunpowder, the thrown cannonballs were made and smashed into the city, and the battle would obviously be much simpler. It is also a helpless choice to use oil-rich pine and cypress grease wood as cannonballs. In fact, it took too long to ignite these stumps, and the flames that burst when they hit the ground were too small. If it weren't for the fact that the Nanzhao Kingdom was all wooden buildings, this method would almost have failed.

And today, when he saw the poisonous phosphorus bomb burst in front of him again, it suddenly aroused Wang Yuan's interest in its production method. In fact, Wang Yuan really planned to leave one or two alive, especially the last four tigers, Song Nan. The intention of leaving him was naturally to ask how to make the poisonous phosphorus bomb, so as to learn the suspected composition of gunpowder. It's a pity that Song Nan jumped off the building directly and fell to his death, which made Wang Yuan very depressed.

But when Zhao Qing and Tan Ping cleaned up the body and searched for the Eight Tigers, in addition to getting a large number of poisonous phosphorus bombs, they also found a half-soaked book on Song Nan's body. The book was already soaked with blood and water, and no one wanted to touch it when it was delivered, so it was only spread out in Wang Yuan's study to dry. Wang Yuan didn't care at first, because the name of the book was "Sun Zhenren Danjing", and at first glance, Wang Yuan felt that this was a boring ancient book about Huang Lao's art and alchemy and immortality. Wang Yuan would never believe this.

But Wang Yuan wondered why there were such books on these Eight Tigers, and Wang Yuan thought that this "Sun Zhenren Dan Sutra" really had a secret recipe for refining what kind of pills to enhance the effectiveness of the pill. Because these eight tigers are all martial arts practitioners, they may find some medicine to assist in practicing martial arts. But after Wang Yuan endured the dirty blood stains and turned a few pages, he found that they were all about some alchemy methods and the effect of the golden pill of immortality.

For example, when writing about the efficacy of the pill, it is written: "The name of the pill is called the Divine Pill." Take a knife Gui, a hundred days of immortals. and swallow it with six animals, and it will not die. and five soldiers. Serving for 100 days, fairies and jade girls, mountains and rivers and ghosts and gods all come to serve them, and they are like human beings. ”

It means that if you eat this pill for a hundred days, you will become a god, and the immortals, jade girls, mountains, rivers, ghosts and gods will come to serve you and listen to your own dispatch. This may be attractive to these Tang people, but Wang Yuan knows that it is all nonsense.

Wang Yuan looked through some and felt bored, and was about to close the book, but accidentally saw such a line of words: "Take sulfur and saltpeter two taels each, use a silver pot or sand jar on the right, put the medicine inside, dig a pit, put the pot in the pit, and the ground, but fill it with soil on all sides, and the soaphorn is not moth-eaten three burn order to survive, enter it one by one, wait for the flame, that is, there are three catties of raw and cooked charcoal on the mouth, and the charcoal is extinguished by one, that is, the embers are not used, and the cold is taken, that is, the fire is ambushed." ”

This line of words is certainly a method of refining a kind of elixir, but when Wang Yuan saw the two terms sulfur saltpeter, he immediately thought that this was actually a formula for gunpowder. Alchemy is made of various raw materials, and alchemists are actually equivalent to ancient chemists, who will refine gunpowder by mistake, but maybe they themselves don't know that it is a useful medicine that can burn violently, and they don't know what its use is.

Wang Yuan's spirits were greatly lifted, and suddenly he realized that the book found on the Eight Tigers was not that the Eight Tigers wanted to refine the pill to become an immortal, but maybe they had created a poisonous phosphorus bomb based on these pill books. So Wang Yuan rummaged through the pages one by one, and the book of just over 20 pages was flipped back and forth more than a dozen times, and finally discovered the secret.

On several pages, someone circled a few words with a brush, and Wang Yuan wrote down these words one by one, and then found that he had obtained a prescription composed of eight medicines.

"Sulfur, saltpeter, horseling, realgar, honey, cooked charcoal, white phosphorus, arsenic. Frost. ”

Wang Yuan looked at this prescription, although some of the things in it did not look like the ingredients of gunpowder, such as the horse bell dou, Wang Yuan didn't know what it was at all. But obviously, this includes the basic components of gunpowder, and it contains white phosphorus and arsenic. Frost, this is the composition of the poisonous phosphorus bomb that Wang Yuan was able to determine. Wang Yuan felt that this was probably the method of making poisonous phosphorus bombs.

After digging through it carefully, Wang Yuan couldn't find the proportion of the formula that was specifically stated, or the effects of various drugs. But at this moment, Wang Yuan was already in a good mood, and he thought of a way. Some of the raw materials on it were extremely precious, and some of them he didn't even recognize, and he needed to find someone to help him study them.

His first thought was to ask Mrs. Qin Guo for help. It's not that Mrs. Qin Guo understands this, but through Mrs. Qin Guo, she can help herself obtain these precious medicines. I don't know where to find sulfur saltpeter horse bells and other things. And in the capital gathered a large number of alchemy monks, although the Tang Dynasty is not as popular as the Wei and Jin dynasties, but there are still many people who believe in Huang Lao's technique, Wang Yuan needs to find a few top alchemists through the wife of Qin Guo to help him, and ask them to help him refine these medicines to see if he can refine the gunpowder that can be used.

Once he had this thought, Wang Yuan couldn't hold back his excitement anymore, and he didn't feel sleepy at all. Despite the fact that it was already more than half of the third watch, he immediately went to the courtyard of the back house where Mrs. Qin Guo lived.

Mrs. Qin Guo had already fallen asleep, and after Wang Yuan and Liu Jun returned safely from the Sanhua Building, after learning that Wang Yuan had eliminated all the Eight Tigers, Mrs. Qin Guo slept very soundly. I have been worried for the past few days, and today I thought I could finally sleep peacefully, but unfortunately I was disturbed.

Wang Yuan went straight into the courtyard where Mrs. Qin Guo lived, and the maid who kept vigil was puzzled at first, but soon relieved. The matter between Mrs. and Mrs. Wang Jiedu is very clear to Mrs. Qin, and when Mrs. comes to Chengdu, Wang Jiedu naturally wants to come over at night. This is not surprising at all.

So the maid who kept vigil immediately woke up Mrs. Qin Guo, led Wang Yuan into Mrs. Qin's room, and then consciously guarded the door, not letting anyone disturb her.

Mrs. Qin Guo leaned over on the bed sleepily and watched Wang Yuan approach the head of the bed, her hair scattered on the side of the thin quilt, her round snow-white shoulders exposed, and she frowned and asked, "Why is Erlang here at this time?" How long has it been? ”

Wang Yuan sat at the head of the bed and asked with a smile, "Aren't you welcome?" ”

Mrs. Qin Guo glanced at him and said, "This is in your house, I don't want your wives and concubines to be unhappy." ”

Wang Yuan smiled: "None of them know about you and me, why are they unhappy?" If Madame doesn't welcome me, I'll go. ”

Mrs. Qin Guo said angrily: "Let's go, okay?" ”

Wang Yuan chuckled, hugged her delicate body and kissed her, Mrs. Qin Guo had already thought about it, but because she was in the Wang family's house, she didn't want to go too far. But since Wang Yuan took the initiative to come, he naturally would not resist. The fire in the hearts of the two of them rose, Wang Yuan forgot what he was here for, after a honey kiss, he pounced on the bed, stripped off his clothes, and entered the port.

Mrs. Qin Guo has been dry for several months and no one has nourished her, and this time she is even more like a fish in water, the two of them pitched up to cater, ecstasy, and became stormy for a while.

The maidservant girl who was keeping vigil outside the door listened to the movement inside, biting her fingers and not daring to move, listening to the moaning of the lady who wanted to die, her legs were soft, and she did not dare to gasp loudly. It wasn't until a satisfied scream came from inside and the sound of the storm died down that the two maidservants outside the door breathed a sigh of relief and hurried away on tiptoe.
