On the moon, Tianlou took Ji Yuluo to the south gate of the palace.

Under the high wall, Tianlou Yao pointed to a piece of land where the lanterns were hanging sparsely and said to Ji Yuluo: "That mansion is the arsenal." Between the Imperial Palace and the Southern Army Barracks. It is the place where the Celestial Empire stores weapons, etc. ”

In the mansion of the moon cage, the rows of staggered one-story houses have closed doors and windows, no lights, no voices, and no popularity, and they look barren.

Ji Yuluo couldn't help but be curious, "What are you doing there?" ”

Tianlou made a silent gesture towards Ji Yuluo, pulling her mansion away.

This huge place is like a granary, sparsely scattered original wooden houses, natural pebbles, weeds and seaweeds, revealing a cold smell.

Tianlou pulled Ji Yuluo to the door of a slightly more independent small building, took out a silver needle thicker than a needle and longer than a needle from his sleeve and poked it in the keyhole.

He smashed the locks as he watched vigilantly.

This place is so silent, and it's a library, how can there be people? Ji Yuluo couldn't help but feel that Tianlou was too careful.

A few seconds later, the lock opened, pushed open the door, and Tianlou pulled Ji Yuluo to tiptoe in.

On the wooden weapon rack against the wall, there were swords, spears, halberds, armor and other weapons, some of which glowed with a faint cold light in the darkness.

"Do you want to steal weapons?" I didn't see Tianlou use a weapon, and this strange thought suddenly popped up in Ji Yuluo's mind. But as soon as she asked this, she wanted to slap herself twice. Tianlou is a golden dragon guard, and he will not go to the arsenal to steal weapons.

The fire fold lit the oil lamp, and Ji Yuluo could see clearly that the floor of this room was paved, the ground was clean and dust-free, and there were few weapons on it. There is a case and a bench in the place where the door is crossed. There is a good set of tea sets on the case, and the four treasures of the study room are all of the highest quality. Hanging above is a lifelike picture of mountains and rivers. On the ground next to the desk are neatly stacked many lake-blue account books. A qiē shows that this is the office of the arsenal. And Kuling is a person with a special status and status.

Tianlou put the lamp on the floor and began to look through the books.

Ji Yuluo suddenly realized that Tianlou was here to check the accounts, but she never liked to read, and she was even more lazy to read those traditional characters. Bore, he took a sword and played with it.

Not good at using a sword, but has martial arts skills. The sword was swung by her with a whirring sound, like flowing water.

After playing for a while, seeing that Tianlou was still concentrating on flipping through the account books, he also stepped forward and asked, "What are you checking?" I'll help you. ”

"Registration of sulfur and saltpeter six and five years ago." Sky Floor Road.

Ji Yuluo abandoned the sword, "Why are you checking this?" ”

Tianlou glanced at Ji Yuluo, looked at her slightly flushed face, didn't speak, only smiled, and buried his head in the account book.

Ji Yuluo also felt that she was talking too much, looking at so many account books, she sat on the spot, picked up an account book and opened it.

Half an hour later, a few batches of sulfur and saltpeter were found in a broken account book at the bottom of the floor, which was indicated to be used for the expansion of Yiqing Lake.

The mixture of sulfur, saltpeter, and charcoal is gunpowder, which is mixed with a certain proportion, and then processed and sealed to explode the mountain, etc.

Yiqing Lake was expanded to the outside of the palace, and the palace walls were wide and firm, so it was troublesome at that time, so raw materials such as sulfur and saltpeter were used. And Tianlou has seen the expansion place after returning to the palace this time, and it is calculated that so many raw materials will not be used at all.

Ji Yuluo opened a pair of big eyes, like a cute kitten, "Why are you investigating this old?" ”

Of course, the purpose of this is to check. Although there is a plan in mind, it needs to be further investigated. The skytower takes time. "Do you know who the Arsenal Order is?"

Ji Yuluo shook her head.

"It's Xiahou Fu's second son." Sky Floor Road.

When Ji Yuluo heard this, she suddenly became interested, "Then check, it's best to find out something." Heal the sin of the black-faced old man's son, and see what he can do! ”

The corners of Tianlou's lips were slightly hooked to the side, "Although he is the son of Xiahou Fu, he is therefore a concubine, but I heard that Xiahou Fu treats him not very well!" ”

"Oh! In this way...... Ji Yuluo was stunned, and then curled her hair before drooping, "I'm confused, I don't understand, you can do whatever you like." ”

I used to play together when I was young, and then I heard Jiang Chumo talk about Xiahou Ye's situation, so Tianlou had a trace of sympathy for Xiahou Ye and Jiang Chumo. And if it weren't for the big things in his heart, he wouldn't have come to the arsenal at night to check these old bad debts.

He didn't answer again, put the account book in his sleeve, blew out the light, and pulled Ji Yuluo out of the door.

Out of the arsenal, the heavenly tower did not stop at the north gate of the palace, but flew all the way to the official residence area.

The night is quiet, and the clean and simple imperial city is like a sleeping lion.

After a while, Tianlou took Ji Yuluo to the Zongzheng Mansion area. Glancing at the door around the corner, he whispered, "Tell me honestly, what are you doing here?" ”

"I killed Xiahou Liu......" As soon as the words came out, Ji Yuluo immediately realized that she was overjoyed and quickly covered her mouth.

Tianlou swallowed the saliva in his throat, "It can't be because he told Xia Hou Zixin that he is the best candidate for the horse, right?" ”

"After my father's birthday, there will be no princess, how can there be a concubine?" As soon as these words came out, Ji Yuluo covered her mouth nervously again, staring at Tianlou in a daze, hoping that he didn't hear the meaning of these words.

In her trepidation, she suddenly realized that she was a big-hearted, outspoken person, especially in front of people who believed and could be presumptuous.

At this moment, Tianlou became more and more sure that his speculation when he went down the mountain was not wrong, and Ji Yuluo must have made some surprising move on Ji Mingshou's birthday. After the big operation, she, the fake princess, will disappear from the palace, and in his eyes.

"You can't kill him!"

Why? Although she didn't ask this, Ji Yuluo's eyes were full of doubts.

Tianlou tried his best to make the smile on his face relaxed, "I've seen your poison needle." Kill invisibly! Others can. But you have to tell me why? ”

Ji Yuluo twisted her eyebrows, and had to say: "Xiahou Liu is the biological father of my maid Xiaogui, but he gave her life, but he didn't care about her, causing her mother to die tragically, and she was sold to the Qinglou at the age of eight...... Forget it, if you don't kill him, you won't kill him, it's okay for me to kill his eldest wife and third wife, right? ”

Tianlou thought for a moment, "Yes!" But it has to be done cleverly so as not to arouse suspicion. ”

The mansion is too big, and it's troublesome not to know the road. Ji Yuluo, who had suffered a loss, asked worriedly: "Do you know the road?" ”

"I've never been here. But the layout of the official residences of the Celestial Empire is similar, and the backyard is also arranged according to feng shui. It should be fine. After Tianlou finished speaking, he pulled Ji Yuluo and jumped over the courtyard wall.

After passing through the quiet and unlit office area, we came to the back house.
