Hou Bufan finally found out what it was, and said in his heart: "Not only did she get the true inheritance of Master Bao Longhao, but she also came out of the basket." I actually made a hot weapon in the era of cold weapons, not bad, not bad, very good!"

Xiao Yu saw that he didn't speak for a long time, and thought that he had said something wrong, so he stood in place even more restrainedly.

When he came back to his senses, he smiled slightly and said softly, "Thank you for telling me this." It's not too early, you go and rest!"

He nodded and left, and Hou Bufan checked the defenses of other places in the border pass, but did not find any loopholes.

Nodding his head with satisfaction, he suddenly felt a terrifying aura on his back, and as soon as he dodged with a phantom strike, he saw a middle-aged man appear not far away.

"Tyrannosaurus senior, why are you here?"

"I am also a member of the mainland, foreign enemies have invaded, and it is within my duty to protect my family and defend the country!"

"I haven't seen you for a few years, you've changed! you've become easy-going, and your mood has improved several times. Judging from the shot just now, the skill should have nearly doubled. ”

"Haha, haha! I can't hide anything from you!"

Hou Bufan also laughed a few times, and the two of them were like old friends for many years, hooking up and returning to his room, chatting and drinking......

Their actions happened to be seen by a thief-eyed person, who immediately passed the news back to the Hunter Sect.

Yin Yu immediately gathered his subordinates and discussed the next matter, but he couldn't come up with a good solution.

"Leech, are you sure to lure Hou Bufan away?"

"Door master, he has no opponents today, why don't we invite some hidden masters to help, he is not an opponent of some old monsters. ”

"That's a good idea!

"The old master of the evil skull gate, the old man with dry bones - skull yin and yang. The seventh generation head of Yinyue Mountain - Yin Chao. Iron Sword Gate Elder Hall named elder - Gong Yuxuan. ”

"These people are old antiques that have been famous for a long time, do you have a way to find them?"

"Just because I can't find it doesn't mean the ghost can't find it. ”

"In that case, immediately search for their whereabouts. No matter what conditions they offer, they will give it to me. I have only one request, let Hou Bufan die. ”

After the secret action of the people of the Fan Sect, the sky gradually brightened.

Hou Bufan chatted with Ba Canglong all night, corrected many detours in martial arts, and made his self-created exercises more and more perfect.

As soon as he returned to his room, he heard the cry of 'wow wow' inside, and rushed in to find three little ones staring at him pitifully.

"Don't cry, don't cry! Uncle has prepared breakfast for you. This sentence was not said casually, but when I came back just now, I happened to meet a maid who was preparing breakfast.

"Liar! You smell of alcohol and say to help us prepare breakfast. Hou Tianyou pulled his trousers and said unrelentingly.

Just when I didn't know what to do, the previous maid appeared with breakfast, and only then did she get the approval of the little ones.

It took nearly an hour for them to eat breakfast, but when he was worried, the catkins came, and the three little ones reluctantly left.

"It's really not easy to take care of children!" he smiled bitterly and ran towards the border cannon.

Before he got there, he saw Bao Wanmei hurrying there with a few of his subordinates.

"Second sister-in-law, what's wrong?"

"I found out how to solve the lack of firepower and came to experiment. ”

"Oh, can you give me a brief idea of what you think?"

"I'm going to make the original gunpowder recipe heavier and add some special powder, so that it can be several times more powerful!"

Before they knew it, the two of them had already arrived at the laboratory, watched her busy for a long time, and finally took out a package of yellow powder and carefully filled it in a small metal container.

Hou Bufan was really shocked, she was able to invent picric acid explosives, and also wrapped a layer of cotton soaked in nitric acid on the outside. If this thing can be mixed, it will be no less powerful than a nitroglycerin-made high-explosive bomb.

"Sister-in-law, be careful, this thing will explode if you don't pay attention. ”

"Third child, looking at your expression, did you already know that this could create a more powerful weapon?"

"I also watched your experiments and got the inspiration!"

Bao Wanmei is such a smart person, he knows that the other party is saving face for himself, and after smiling slightly, he fiddles with the things in his hand.

Time passed, and finally after three hours, she got it and carefully took it to the back mountain to prepare for the experiment.

"Sister-in-law, you don't know martial arts, let me detonate it!"

Hou Bufan took it forward for nearly 100 meters, found a very safe place to place it, and lit the fuse.

It used several phantom strikes in a row to rush to Bao Wanmei's side, enveloping all his power around the two of them.

A deafening explosion rang out.

The powerful shock wave quickly rushed into the distance, scaring the surrounding soldiers and generals all rushing to the source of the sound.

"Second sister-in-law, I really admire you so much, you can get such a thing!" gave a thumbs up.

Bao Wanmei was also very excited at this time, and kept shouting in place, if there was a history of not knowing her, no one would have thought that this was the person who surpassed Master Bao Longhao.

"Lord Lu, Empress, are you alright?"

"It's okay, it's just an experiment!" the generals made sure they were all right, and then left.

The sound here also alarmed the Buddha shrine and others, and they came to know that they were experimenting.

"Queen, you can imagine how powerful it is from the explosion just now. Is the technology mature? Can it be mass-produced?"

"It's still lacking, and when I'm researching it for a while, I'm sure I'll have energy. ”

"I said second brother, second sister-in-law! You have only been married for a few days, and you are doing what you are doing after your honeymoon. I'll leave the border affairs to me!"

"We also want to live a quiet life, not to clean up these excessive dregs, once they are allowed to enter the mainland, it is the people who suffer. ”

"The second sister-in-law really didn't let me shave my eyebrows, which made me, the lord of the land, feel ashamed. Okay, let's kill these bones first!"

Everyone nodded, going about their own business.

In the next time, Hou Bufan helped her experiment together, and under his intentional or unintentional inspiration, he finally came up with something that could be substituted to make high-explosive energy production.

The masters who can make gunpowder in the entire Panlong Continent are basically gathered at the border gates, and more than 20 large factories have been opened in a row, producing explosives day and night.

Hou Bufan was very worried about their safety, and he kept running in major factories, although there were some minor accidents, but no one died.

Time passed, and a large amount of gunpowder was available, and the shells were made into a difficult situation.

Just when everyone was in a hurry, the space blockade was lifted, and the masters of the Gopher Drill Tribe easily solved the material problem, and a large number of giant cannonballs were created every day.
