Li Huaiyun and Mu Kite followed the guards to the armory.

This place is the key place of the Great Zhou Army, and all kinds of dangerous blades and materials will basically be placed here in batches.

At the same time, heavy troops were sent to the entire armory, taking turns to take care of them 24 hours a day, and in the surrounding area, four patrols were on duty to guard, and the Demon Slayer Division also sent a lot of first-class demon catchers to guard the area outside the arsenal, secretly guarding the safety of the armory, ensuring that there would be no monsters and could enter from the outside.

Li Huaiyun and Mu Kite stood in front of the armory gate, and the guards pushed the two huge wooden doors open.

The two walked in and directly found a vacant lot inside, and then, Li Huaiyun summoned Narcissus out and asked her to find the materials she needed in the armory together.

When this female ghost first came out, she thought that there was something happy to do, but it turned out that it was these trivial things, and she was quite dissatisfied with it, and always felt that she was like a coolie!

It's just that the other party is her own master, and she can't say anything, so she can only help, collect the materials she needs, and remind everyone who helps, where to put the things!

The appearance of Narcissus also alarmed the nearby demon hunters, and after Li Huaiyun's explanation, they believed it, and at the same time expressed envy to Li Huaiyun and reminded him to be temperate.

The wooden kite started on its own, experimenting and making objects according to what they had previously thought.

Li Huaiyun helped a little at first, but then remembered something else, so he left alone, he put his hands behind his back, and walked around the huge armory, thinking about this in his heart.

Ever since he began to investigate the case of the monster, he has been speculating about the ultimate purpose of the black-robed man, but because the clues are too complicated, he has not been able to straighten out these clues.

At the beginning, the official of the Ministry of War was responsible for managing the armory, and any objects that entered and exited the armory would pass through him, so when he got here, he would definitely be able to find useful clues.

He went to the table in charge of the armory, and asked the newly appointed official to give him the notebook to look at.

The other party expressed doubts about his identity, and the armory was a military aircraft center, and without instructions and orders from above, he must not let others investigate at will.

However, after Li Huaiyun took out the emperor's edict, he immediately changed his attitude, and handed over the record books respectfully, and at the same time, he was glad that he was not too tough, which gave the other party a good impression.

He stood up and respectfully handed the notebook into Li Huaiyun's hands, "Li Gongzi, if you have any questions, please tell me, I will be responsible for it and answer it together." ”

Li Huaiyun stood there and flipped through the record book in his hand, "When is the latest time recorded here?" ”

"About three years!"

Li Huaiyun pointed to the other record book on the table, "Find them all for me, as long as there are large quantities of delivery records in it, point them out to me." ”

"Okay!"

The two of them began to flip through the ledger on the table, and the place was cold and damp due to the remote location of the armory.

The official found one first, "Li Gongzi, look at this one, whether it meets your requirements,"

"One hundred pounds of charcoal! It was seven years ago, when it was freezing and the palace urgently needed a fire to warm up! ”

Charcoal, the composition of wall ash is fire and nitrate! Li Huaiyun thought to himself, could it be that they want to make gunpowder?

"Quick! Help me flip through and see if there is a record of a large amount of sulfur. ”

The two of them rummaged through the record book again, although there were records on it, but the amount was not much, and it was also within the normal range.

"It seems that there is no more!" The official shook his head, "At most, it's only about one or two catties,"

"At most, that's all?"

"Yes! That's all left for this month. ”

"Then write down all the records that only have one or two catties left."

The official nodded, "Then Li Gongzi wait here for a while!" ”

The officer was just trying to show off it, and he stood there, flipping through the notebook on the table quickly, and quickly recorded what he had heard in his head.

As with most of what they had speculated, the records were split up many times and were a bit hard to find.

After a long time, the man finally copied all the records.

He pointed to the record book on the table, "Li Gongzi, please see, these people have taken a total of hundreds of catties of sulfur in four or five years, which seems to be divided into batches, and I think it is very little, but in fact, it should be a lot." ”

"Someone is doing this strange thing again!"

As for charcoal, Li Huaiyun suddenly remembered that the dry locust tree, if burned with fire, could make charcoal powder.

He slapped his thigh sharply, and sure enough, let me guess, collect these things to make black powder.

Wait a minute! If that's the case, wouldn't the Qihua Palace be in danger!

Li Huaiyun was suddenly startled in his heart, and rushed to the gate with an anxious face.

On the way, I saw that the wooden kite was still making a trap, and because the situation was urgent, and I didn't want the wooden kite to be distracted, and was ready to tell her.

"Where are you going?"

"I've found some more clues, and I'm getting ready to go over and check them out!" Li Huaiyun said as he ran.

Leaving the armory, Li Huai used the token of the Demon Slaying Division to call a few demon hunters to accompany him, many people are easy to do, and they can help.

Li Huaiyun ran towards the Qihua Palace, and on the way, he had already seen the green smoke rising in the distance, and he was afraid that someone had already set fire to the Qihua Palace.

He quickened the pace of his journey, and then asked the other demon hunters to divide up and besiege Qihua Palace.

As soon as Li Huaiyun stepped close to Qihua Palace, he saw that half of the locust tree had already burst into flames, taking advantage of the situation to bring up the weeds in the surrounding area, and the smoke was gradually getting bigger.

He immediately ran into the house, took out the old basin from it, and threw it directly at the lack of water, ready to extinguish the fire.

When he threw the water at the trunk of the tree, the flames suddenly exploded violently, and they rose even more violently.

Li Huaiyun was stunned for a while, and then he remembered that this locust tree had probably been anointed with oil, and the fire was even more fierce for a while!

At this time, thick smoke continued to rise, which had already alarmed most of the palace, and those eunuchs, guards, and palace maids all came to put out the fire.

It took a long time to extinguish the fire, and the weeds in the yard were burned.

Li Huaiyun looked at the locust tree that was still burning on the ground, the trunk had been burned to black charcoal, and he really couldn't imagine that he would actually touch the oil on it, when was it applied.

From the beginning of the firefighting, he stood at the gate, looking at the people who were fighting the fire inside, and thought a lot before, if he could apply oil to the trunk of a tree and then set it on fire, I am afraid that only people who have been to the imperial dining room will be the only ones who have been there, and only they have the ability to bring out this kind of thing? This is quite doubtful.

And the person who did this, if he didn't leave, should have been able to leave unharmed only after participating in the firefighting, and then taking the opportunity to mix inside, and finally leaving the scene.

After extinguishing the fire, he closed the gate of Qihua Palace, and then carefully observed behind him one by one.

Finally found a suspicious person, who was ordinary-looking, wearing a guard suit, and his entire back was covered in sweat.

His expression was calm, his breathing was quite even, not like the others, they were all a little out of breath, although there were some traces of charcoal burning on his clothes, but it was very much like he had made it like this on purpose.

Li Huaiyun stared at the man the whole time, observing his every move, and after putting out the fire, it was handled by the chief of internal affairs, and the others dispersed.

He secretly followed the man and came to Concubine Rong's bedroom, although there was no one in this palace anymore, he still took a few guards and was guarding in front of the gate.

At this time, the sky was gradually darkening, and the man walked along the stone road to Concubine Rong's bedroom, and the red walls on both sides were particularly dull in the dusk.

"You set the fire!" Hearing this, the man's voice immediately became alert.

Li Huaiyun walked up and shouted at the back. "No need to go to the car to find out,"

The figure shuddered suddenly, stopped, and then slowly turned his head, the man had a gloomy face, "Who are you?" ”

"I was the one who found out that the locust tree was on fire, and after a while of thinking! What do you think your son of heaven has to do with me! ”

"Yes! Fortunately, you found out in time, so you didn't let the palace catch fire! ”

"Oh! A fire is not exactly what you hoped for! ”

When the man heard this, his face became more and more gloomy, "What do you mean by this, we are all on errands in the palace, of course we don't want to... ”

"Don't pretend! You used to be an errand boy in Qihua Palace, but now? It's not like you're going to set a fire yet! ”

The guard turned around and pointed at Li Huaiyun, "Don't spew blood." ”

"Bloody mouth! Then you are admitting that you used to be an errand boy in Qihua Palace! ”

"You..."

"In the case of the princess falling into the water, someone fell ill and died, so he escaped, I thought there was a eunuch, but later by examining the body in the trunk, I found that the eunuch should not have such strong strength."

Li Huaiyun gently pinched his knuckles, "Then it is only possible to protect this kind of person, who has some martial arts cultivation in itself." ”

The guard smiled, as if he didn't want to hide it, "All these years, I have been hiding, not daring to show my head in front of people, just for fear that someone will recognize me, thinking of today, someone really has seen through my identity." ”

"Does the princess's death have anything to do with you?"

"What do you say? Someone wanted to harm her, and I killed the person who harmed her, is it a disguised revenge for the princess! ”

"You're quite good at talking, why don't you say it, you're an accomplice, in order not to be recognized, you killed another accomplice!"

"Humph!" The guard clenched his hands into fists, "Now that you know everything, why should I ask!" ”

"Who told you to do that!"

"I want to do it myself, can't I?"

Li Huaiyun frowned, "It's all this time, you are still defending that person, how much benefit did he give you!" ”

The guard's eyebrows were upside down, his expression was angry, and he stared at Li Huaiyun fiercely, "This is what I thought, no one gave me benefits!" ”

"Don't talk nonsense! You are a guard, how can you not think of harming the princess! ”

"Unless it was instigated by another princess, however, the princess is nowhere to be found, and you don't have to hide it anymore, anyway, you have confessed to the crime of killing your head, why don't you dare to say who instigated it? Could it be that he is afraid of dying directly? Or what does Concubine Rong have with you? ”

The guard snorted, "I can't believe I'll be able to get out of here!" ”

Li Huaiyun sank down and clenched his fists, "Who said you could leave?" ”

"I said it!" The guard swung back, only to find that a strong force was coming straight to the door.
