Lu Yueding naturally knew that when cultivators made magic weapons, they had to communicate with the aura of heaven and earth, pay full attention, and some top-level magic weapons had to be laid out to prevent the invasion of evil demons. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

Lu Yue nodded fixedly: "I see, it's okay, our family can see Mr. Houlong refining magic weapons with our own eyes, and it can be regarded as a great fate." In this way, let's all go to Mr. Houlong's place to make magic tools and wait, put on the incense case, prepare drum music, and wait for the magic weapon to be born, and Mr. Houlong will go out of the customs and issue an edict immediately. ”

Li Hua coughed: "That--thank you Gonggong Lu for your kindness, but the senior brother in charge has instructed that the magic weapon he newly refined is extremely dangerous, so it is strictly forbidden for anyone to approach the laboratory--Senior brother deliberately moved the laboratory to the mountains for the sake of this magic weapon, just for fear of hurting people." ”

Li Hua didn't say a word, Lu Yueding finally couldn't hold back, no matter how good his temper was, no matter how deep his qi cultivation kung fu was, he was rejected one after another, and he was also angry. He slapped the table heavily and said sharply: "This is not good, that is not good! If this holy decree misses the auspicious time, who will bear this great responsibility?!"

The angel was furious, and all the people in Houlong Village panicked, although they had been influenced by some of Guo Dalu's modern education, but in their bones, they were still obedient to the people, and they didn't dare to come out in the face of ordinary officials, let alone the envoy who represented the saint.

Li Bo trembled and said to Li Hua: "Uncle Shi, why don't you ask Gonggong Lu and his entourage to move outside the laboratory, as long as they are far away, through the explosion-proof wall, and stay in the trenches, it will be no big deal." ”

Li Hua looked at the old village chief Zhu in embarrassment, and the old village chief Zhu nodded again and again: "Medium, medium, just do it!" Zhao Kang, Huang Xiao and others next to him also said in a loud voice, the explosion-proof wall and trenches were all built by them, and they can definitely ensure safety.

Li Hua personally led the way at the moment, accompanied Lu Yueding and his party, came to the mountain, blowing and blowing all the way, and finally came to the outside of the laboratory, the so-called laboratory is actually a natural cave, the granite cave is extremely hard, but the strange thing is that the mouth of the cave is piled up with layers of sandbags, and there are explosion-proof walls erected outside the cave, and the outermost is a trench with a twist and turn.

Guo Jin, Brother Hao, Da Niu, and Chen Qingdai were guarding in the trench, poking their heads out anxiously from time to time and looking into the cave, but unfortunately, there was no sound in the laboratory of the black hole.

Seeing such a noisy team outside the cave, Guo Jin was stunned, and hurriedly climbed out of the trench with Brother Hao to greet him: "Li Hua, Old Village Chief Zhu, what's going on?"

Li Hua shook his head with a wry smile, and hugged his fists at Lu Hou Dingxu: "This is the decree that made Lu Yue Ding Lu Gonggong, who came from the capital and canonized Guo Ge'er with Danshu iron coupons." He turned his head to Lu Yue and said, "This is the father of Mr. Houlong Guo Dalu, Guo Jin, who was originally the leader of the army--"

Guo Jin shook his head and interrupted Li Hua's introduction: "I have forgotten all the things in the past, and now I am Guo Dalu's father, an ordinary farmer." The villain thanks Father-in-law Lu for coming all the way to Houlong Village to pass the decree, Xiao'er Guo Dalu is refining an extremely important magic weapon, we have been waiting outside for more than ten days, and there is still no sound, I can't greet my father-in-law in person, I'm really sorry. ”

Guo Jin faced Lu Yueding, but he was neither humble nor arrogant, Mr. Houlong Guo Dalu is his son, even in front of the emperor's old officials, his waist is straight - my son invented alcohol and steel, and even stole the divine beans from the Nine Heavens, this immeasurable merit is that the emperor's old officials have to be polite.

Brother Hao, Da Niu and Chen Qingdai next to them only made a false salute to Lu Yueding, and their hearts were all on Guo Dalu, what kind of angelic envoy to deliver the decree, how could the safety of Brother Guo be important? Especially Chen Qingdai, she is a dragon body, and she doesn't pay attention to the emperor of the world, and when she salutes and makes a blessing, she doesn't fork her hands, but squats slightly.

Lu Yueding didn't dare to show his face at Guo Jin, and said with a smile: "It turned out to be Lord Guo, congratulations to Lord Guo, this time the saint canonized Mr. Houlong, but after three generations, you, as Mr. Houlong's biological father, also named a viscount--"

If this news was placed in the past, Guo Jin would have to be happy to dance, he used to be bloody in the army of the Vietnamese army, scarred, beheaded countless times, and he was just a leader, not to mention the title, but now, he has long looked down on the wealth of the world, and now he just nodded slightly, thanked him, and stretched out his hand to make a gesture of please: "Gonggong Lu, let's go to the trench." ”

Lu Yueding glanced at the narrow and damp trench, twitched the corner of his eye, and said a few times: "No, no, our family still stands on it, and when the decree is issued, we have to put incense on the table and play drum music, this is really not easy to do in the ditch." ”

The big girl said kindly below: "This uncle, staying in the trench can be explosion-proof and safe." ”

Lu Yueding still shook his head, and Chen Qingdai pulled the big girl: "Don't pay attention to them, this kid Guo Dalu has been in the cave for more than ten days this time, but I'm getting more and more worried, or I'll go in and take a look? I'm running fast, what's wrong, just pull him and escape." ”

The big girl stretched out her hand and wanted to grab Chen Qingdai, but halfway through her hand, she glanced at the gauze on her fingers, and suddenly retracted it again: "Don't, Sister Daiyu, Brother Guo repeatedly told us not to enter the laboratory, I see that he has a very serious face, let's listen to him." ”

Chen Qingdai thought about it, even if she was not by Guo Dalu's side, Bai Suzhen must be secretly protecting each other, so she didn't have to worry too much. , she nodded, and continued to stare at the cave without blinking—because of the blast wall and sandbags, with her good eyesight, she couldn't actually see anything.

Lu Yueding listened to the conversation between the two girls in his ears and shrugged his shoulders, the magic weapon refined by Mr. Long is really so powerful? Da Luo Jinxian's innate treasure has the ability to move mountains and seas, but the magic weapon refined by the cultivator the day after tomorrow will definitely not have such great power, under normal circumstances, the magic weapon of subduing demons and eliminating demons is mainly thunder, no matter how powerful this thunder is, with that sandbag and wall blocking, can it still threaten himself?

At this time, Li Bo quietly asked the villager supervisor to move a few benches, and set up an umbrella, so that the group sat outside the cave, and there was a small number in front of Lu Yueding, on which there was tea and newly baked snacks from Wangjiang Tower, Lu Yueding nodded slightly at Li Bo, holding a teacup, half-squinting his eyes, waiting for Guo Dalu to come.

Guo Dalu was busy in the cave, and he didn't know about the farce that was being staged outside the cave, and this experiment was not trivial, because he was preparing nitroglycerin!

That's right, nitroglycerin - the most basic raw material for modern explosives!

Guo Dalu finished tossing the entertainment industry in the big world, and after returning to Houlong Village, he received a report from Chen Qingdai and Li Dayan - Fengshenshan Mine was attacked by monsters!

Guo Dalu immediately rushed to the mining area, and even followed the vine, under the guidance of Chen Qingdai, found the nest of the monsters in the sinkhole, but in addition to seeing a pile of **** white bones and dilapidated furniture, the monsters inside were nowhere to be seen.

But after Guo Dalu returned to Houlong Village, he didn't dare to take it lightly, this is not the first time that Houlong Village has been attacked by monsters, the last time the monsters in the Batu Cave attacked in Xiongchumei, it has been proved that black powder is no problem against ordinary humans, but it is "faster, higher and stronger" After all, not every time a shemale fights, they can find a good terrain in advance and bury a large amount of black powder like a mine - the situation at that time was actually extremely dangerous, as long as the monsters changed the direction of attack, the large amount of black powder would be invalid.

Guo Dalu needs more efficient explosives!

Black powder must achieve leapfrog development and directly enter the era of yellow explosives!

Guo Dalu was a little hesitant to introduce gunpowder and hot weapons into the Great Li Dynasty before, not knowing if he would bring about a series of chain reactions and become a small butterfly with the wrong wings in time and space.

However, the world of cultivating immortals in the Great Li Dynasty is even more powerful than Guo Dalu imagined, not to mention those immortals who have achieved cultivation, even the wild goblins in the Fengshen Mountain have good combat power, and the two battles were won by Guo Dalu and Houlong Village.

However, not every time the goddess of luck is on Guo Dalu's side, before Guo Dalu has figured out how to use the power of merit to cast spells, Houlong Village must have a powerful weapon, so powerful that whether it is a demon or a fairy Buddha, he will not dare to provoke easily!

Naturally, this is a thermal weapon!

Therefore, the research on explosives immediately mentioned Guo Dalu's most important research project.

Is it difficult to develop modern yellow explosives?

It's not hard.

Because all the processes, experimental formulas, and precautions are clearly written in Baidu Nobel entries.

Yellow explosives have two major raw materials, sulfuric acid and nitric acid.

Sulfuric acid is a basic ingredient for cultivators' alchemy, called alum oil, which is dry distilled from alum stone, and as for alum stone, this is one of the most common medicinal materials in Chinese medicine stores.

Nitric acid is obtained from saltpeter.

Sulfuric acid and nitric acid are mixed in a certain proportion and reacted to obtain light yellow nitroglycerin.

However, as soon as this thing is exposed to sunlight, or a slight collision, it will explode violently and cannot be used safely, but don't worry, there is a solution in the Baidu entry - Nobel drips nitroglycerin into porous diatomaceous earth, and it is prepared into a safe solid explosive, which is detonated with ordinary gunpowder. Although the power of this solid explosive is only three-quarters that of nitroglycerin, it is enough to use. (To be continued.) )
