Binglian listened to the middle school chemistry knowledge roughly some time ago, although there are many similarities between chemistry and fire magic, and there are more places that can be learned and inspired, but due to the backwardness of the equipment, there is no reliable verification method. Pen, fun, pavilion www. biquge。 Info This time, when I heard that Jiao Ming wanted to do a verification test, I was naturally interested, and asked: "How to do it?" and then guessed with the chemical knowledge of half a bottle of water: "Depending on the color of the iron salt solution? But if there is no acid, then the metal replacement reaction will not work." ”

Jiao Ming waved his hand to interrupt Binglian's words, and said his own method: "One is to measure density, which is simple but has a large error, and the other is magnetism, although it is accurate but somewhat complicated, and some things need to be determined first." As he spoke, he pulled out a worn-out magic lamp pinned to his waist. This is borrowed from Vera, and after disassembling it, it will be returned if it can be assembled, and if it is not assembled, it will lose some metal.

"What are you doing with this? Experiments will stay until dark?. "You can see it at a glance. ”

Next, Jiao Ming and Binglian were the two leaders, Luo Hua and Xia Feng were assistants, Huang Xia Zimang sisters and brothers and a few diligent fire magician apprentices also helped, and several guarded high-ring magic warriors watched. And so the experiment began.

The experimental process is roughly as follows: first, the same volume of water as the small hammer is taken by draining the water. Then use the long hook as a lever to hang a small hammer on one side and a small bucket on the other, which contains the same volume of water as the small hammer. Finally, hang an empty bucket again to eliminate the influence of the keg. The distance between the hanging point and the fulcrum point on the hook lever is taken as the data to calculate the density ratio of this metal to water.

The simple experiment was carried out five times, and the average result finally came to be seven and five, and Jiao Ming pouted at this number and began to move on to the next step.

Remove a bit of metal from the long hook, clink it into a filament more than 20 centimeters long, wrap it around the handle of the small hammer with a paper pad, and attach the two ends to the energy storage pool that was removed from the magic lamp. After the trouble ice lotus charged the energy storage pool, Jiao Ming took the hammer handle to touch the sledgehammer and the long hook, and sure enough, there was suction, and he scratched it in the soil again, absorbing a small amount of black particles.

Although there are three kinds of metals with magnetic reactions, iron, cobalt and nickel, the other two are not common and are not easy to smelt, so it should be ruled out, so it can be concluded that this is iron.

Seeing this miraculous phenomenon, everyone experimented with their own hands, and was amazed. Binglian frowned at first, and then exclaimed, "Alchemy Stone!?"

"Oh, what's that?" Jiao Ming was intrigued.

"It is rumored that alchemy can extract metal elements from everything, which is one of the core secrets of alchemy, and more is unknown. ”

"Hmph, the stench of mysticism. Jiao Ming sarcastically said that he no longer asked, but began the experiment of forging steel by soil method, intercepted the next section from the long iron hook again, drew a dagger pattern and asked Binglian to find a forging man. Ice Lotus was inexplicable, but she still pulled a crocodile family magic warrior who was guarding the furnace over.

Jiao Ming smiled when he saw it, he was still an acquaintance, and he was a teenager who came to Changteng Town together when he was sick. The acquaintance is easy to do, and after a few polite words, he handed over the dagger pattern to the other party, and explained: "This is a very important experiment, as for how long the forging will last, I don't know, just fight for a day, and I'll see the effect tomorrow." ”

"Understand! Don't worry. The boy nodded in response, and threw a fist-sized piece of iron into the stove, with the tongs in his left hand and the hammer in his right hand waiting aside, his resolute expression reflected red by the fire.

According to the feudal system of the crocodile lord, the boy is considered a subordinate of the crocodile duke, and the two can only consult with him. But there is no need to be so troublesome in the face of the three fire magicians by the fire, because this group of hired fire magicians is a direct subordinate of Ice Lotus like the twenty or so little guys in Shining Scales, so when the three of them heard Ice Lotus's order to work overtime, they could only nod and accept it with a bitter face.

As soon as the experiment came to an end, Rosea immediately reported that the five had just returned and were waiting outside the pit. Jiao Ming had been waiting for these five guinea pigs for a long time, and when he heard this, he was overjoyed, and said goodbye to the ice lotus and went out of the pit to meet them.

The five people of Zhuoshan saluted Jiao Ming in return, and the two sides exchanged a few polite words. Jiao Ming noticed that the five people were in gray clothes, Zhuo Shan, as an ordinary person, was quite tired from hurrying, and the remaining four people were in a good mental state, but there was a look of doubt in their eyes, obviously the messenger did not explain too much.

"The plan to go out to prospect has been cancelled, and you have a new mission. But Zhuoshan, you go back to the castle area to rest for a while and talk about it in the evening, there is no other meaning, it would be a pity for you to be tired like this. The remaining four come with me. Jiao Ming directly commanded. Zhuo Shan opened his mouth, but in the end, he just nodded away with complicated eyes.

The environment under the quarry pit was not good, full of noise and haze, so Jiao Ming, who was going to give the four of them a small test, picked a quieter place, and took the four of them to the small grass shed that was originally for the ice lotus to rest, and began to check the space teleportation technology of the four people.

The results were unsatisfactory, and three of the four had reached the level before Jiao Ming's illness, barely able to touch the wall of Siccton. A woman who doesn't know whether she is smart or stupid actually faked it at the beginning, and she didn't cast a spatial teleportation in a completely flattened space, so every teleportation was not accurate at all. Even if he casts the spell directly below, only five out of ten times he can touch the wall of Sicodon, and he can't tell where the rest of the situation is crooked.

Jiao Ming patted her on the shoulder helplessly and said, "Eldest sister, it's too late to change now, don't say I didn't remind you." Then he took out the white silver ring and stuffed it into the arms of the six-ring magic warrior, and said, "Try again now." ”

It's not that Jiao Ming is partial to this person, but he just thinks that the magic warriors of the Six Rings are closer to his own situation, and they are more practical and durable. The six-ring magic warrior fiddled with the silver ring, and then cast his magic as he was told, but still only teleported out a black grit.

"Nothing else, like it's easier to cast magic, or what's the barrier going on?"

"Nope. ”

Jiao Ming frowned and didn't like this beginning, and handed the silver ring to the other three people, but to no avail. Jiao Ming still didn't give up, and asked for some magic addiction potions from Binglian for the four of them to drink, but it was still useless, and now Jiao Ming really scratched his head.

"What's wrong with us?" a young female apprentice asked tentatively as she saw Jiao Ming's displeasure.

"It's okay, it's okay, I'll teach you another trick. Jiao Ming began to teach a few people the magic skills they 'saw' from Semeer, but a few people's learning ability was limited, and they didn't even touch the door until the sun set.
