Shenlei is now the most important weapon of the country, and has played an extremely important role in both counterinsurgency wars. However, such a powerful weapon is also prone to frequent accidents, and if it suddenly strikes out in the middle of a war in the future, and injures itself before the enemy, a catastrophe will occur.

As the emperor, Zhao Lao Er may not care about other things, but if he can't witness the difference between the divine thunder made by Wen Qihang and the divine thunder made by the imperial court, how can he rest assured.

Under the leadership of Wen Qihang, the group walked into the Shenlei workshop.

It is surrounded by water on three sides, and there is an open-air pool in the small square in the middle, in which some lotus flowers are planted, and some brocade carp are actually fostered in the water, swimming leisurely.

Zhao Lao Er saw two houses similar to greenhouses, with a distance of more than fifty zhang apart, so he asked: "This is where the divine thunder is made?" ”

"Yes, official." Wen Qihang replied.

"Well, let's go in and have a look." Zhao Lao Er nodded and ordered.

"Official, this is too dangerous, your dragon body is important." The drug test attendant anxiously persuaded him.

"In such a dangerous place, Wei Chen went in to check it out, and you must not take the danger lightly." Shi Shouxin also gave etiquette and persuasion.

After all, the Shenlei workshop located in the palace always explodes for no reason, and the dead and injured craftsmen are not a small number, and now as long as they are named to go to the Shenlei workshop to work, those craftsmen have to wear three incense sticks every day in the morning and evening, pray for the blessing of the gods from all walks of life, and explain the aftermath before going to work in the workshop with fear.

Zhao Lao Er didn't answer, but looked at Wen Qihang, since he is the emperor, the body is not his own, it is a matter of social safety, naturally he can't be willful, but he really wants to understand the characteristics of Shenlei, so he has to ask Wen Qihang, an expert, to see what he has to say.

"Although the officials can rest assured, all the officials can also be relieved, there will be absolutely no accidents here." Seeing Zhao Lao Er looking at him, he reassured with a smile and a smile.

"Wenjue, you have to be cautious, the official family bears the weight of the society, how can it be lightly involved." The drug test attendant said in a dissatisfied tone.

"Since Saburo said that there is no danger here, then let's go in and have a look." Zhao Lao Er said with a smile.

"Official .......," the drug test attendant immediately knelt on the ground and wailed.

"I know you're loyal, but Saburo definitely won't be bad for me, let's go in and have a look." Zhao Lao Er interrupted the drug test attendant's wail.

"........." Hearing Zhao Laoer's order, everyone in the audience suddenly turned black for a while, Zhao Laoer wanted to go in and die, not to mention, he actually had to bring everyone.

"Official, it's not appropriate to go in with too many people, it's appropriate to take three or five people at a time." Hearing that Qihang saw that everyone's faces were dark, he persuaded him.

"Well, it's up to you here." In the face of such a dangerous thing, Zhao Lao Er did not intend to be strong.

"Official, please."

Under the guidance of Wen Qihang, Zhao Laoer saw for the first time the complexity of entering and exiting the workshop.

First, I went to a place called the dressing room, took off all the clothes on my body, and changed them into underwear made of Jibei cloth, and the shoes were a kind of cloth shoes called mille-feuille soles.

After changing clothes, you should also stick your whole body on an iron pillar and rub it a few times, especially your hands, which must be kept on for a while.

After completing a series of tedious procedures, he walked out of the locker room, walked into a separate room, and pushed open a heavy wooden door inside, only to see the place where the divine thunder was made.

The ground is paved with loess, there is no gold in the room, the tools used are all wooden, and a rain urn full of clear water is placed at intervals, and the water surface is sparkling from time to time.

Several students were wearing something called masks, and they were concentrating on matching Shenlei.

Seeing the huge wooden platform on the ground, all the raw materials were placed, and the finished product of the divine thunder was not seen, Zhao Lao Er asked suspiciously: "These are the raw materials for making the divine thunder, where is the finished product?" ”

"Qiqi Guan's family, if there are thirty catties of finished products made, they need to be stored separately, which is another house we just saw, so the finished products that can explode here will definitely not exceed thirty catties, as long as you pay a little attention, it will definitely not cause harm to human life." Wen Qihang explained: "Of course, this is also the advantage of small batch production, after all, the number used in the Jue Mansion is very small, and if it is a large-scale production, it will need to make separate rules and regulations." ”

"Oh, let's go and have a look at the finished product." After Zhao Lao Er carefully checked this place, he proposed to take a look at the place where the divine thunder was stored.

"Weichen suggested that it is better not to go, after all, there are finished products of divine thunder there, even if it is just in case, the official family should not take the danger lightly." Smell the sailing rules and persuade. There is a grenade in it, how can it be easily known by Zhao Laoer.

"What Wen Jue said is extremely true." The drug test attendant had been worried about it, for fear of sudden accidents, but when he heard Wen Qihang say that the divine thunder items stored here were not enough to be fatal, he eased his emotions. Now when he heard that Zhao Lao Er was going to a more dangerous place, his heart suddenly lifted, and now when he heard that he had set sail so well, he immediately felt a little excited.

"Anyway, the finished product is nothing more than these, just in more quantities, but today I have seen the complicated methods of making divine thunder. Saburo, can you explain the purpose of our change of clothes? Zhao Lao Er asked. This is what he is most puzzled about now, changing clothes must have a direct relationship with entering and leaving the Shenlei Workshop, especially the iron pillar.

"It's such an official family, the coarse linen clothes we often wear, sometimes produce subtle thunder and lightning, Weichen calls static electricity, this static electricity can sometimes be seen by the naked eye at night, but it is basically difficult to find it during the day.

Sometimes we undress and have the feeling of being pricked by needles, which is caused by static electricity, which is very easy to cause the sudden explosion of thunder, especially in the hot summer, the environment is dry, and it is even more dangerous.

Although Shenlei is afraid of moisture, keeping the indoor moisture moist can prevent this thing from occurring, and a slight dampness can be ignored, after all, safety comes first. Wen Qihang patiently explained: "And the use of loess paving, is also the same effect, in case there is a heavy object on the ground, if it is bluestone paving, under the two frictions, it is also very easy to have sparks, and loess paving will avoid this situation." ”

These knowledge in later generations is popular science knowledge, but now it is the top knowledge, waiting for idlers, etc., it is difficult to contact, smell the voyage like a few treasures of the story, but a few people present have long been stupid.

"Sure enough, there is knowledge everywhere, and the details are true. San Lang, you have to tell me about this knowledge often. Zhao Lao Er said with interest. Thinking of the Shenlei workshop he set up in the palace, he thought that the best materials were used, especially the white marble paved ground and the utensils made of iron, and his heart was embarrassed.

"Official, this doesn't seem to be very good." Wen Qihang said in embarrassment.

"Why?" Zhao Lao Er wondered.

"Because all these studies have been banned by the imperial court?" Wen Qihang said helplessly.

"How could the imperial court ban such useful knowledge?" Zhao Lao Er was surprised.

"Because these studies are recorded in the "Elementary Stages of Arithmetic" compiled by Wei Chen, and this book, you know." Wen Qihang smiled bitterly.

“.........”
