In the afternoon, the ten metal carriers inlaid with magic beads were made, and the rest of the work was done by the Qur'an. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

I saw ten bottles of solution on his workbench, the color was dark red, and there was a faint smell of blood wafting out after uncorking the bottles, and the names on the labels on the bottles were the five birds and five beasts, and it was their blood.

Gu Lan also held a bottle of pale green liquid in his hand, which was the juice of Gastrodia Crisp, Gastrodia Crisp is a plant that is difficult to pick, only grows in the cracks of cliffs, has a strong anesthetic effect, and is also widely used in medicines, and the largest shipper is the Rock Cat Department, only the pickers they trained dare to climb the steep cliffs, and the price of Gastrodia Crisp remains high under their monopoly.

Gu Lan poured three drops of pale green juice into each bottle, and after a short time, the blood in these bottles began to change, but some were violent and some were weak, and they were not the same.

Ota watched and found bubbles coming out of the existing bottle, but the bubbles were slowly bulging due to the thick blood. In the other bottle, the water in the glass is slightly shaken, and it starts from the middle to ripple slightly. In some cases, the color began to change, and the bright red color gradually became thinner and transformed into a pale pink......

Guran knew Ota's doubts, so he explained: "The blood of each animal looks the same but is actually different, because the blood contains unknown things, and they are different in shape and size, so this kind of thing in the blood is also of different strengths, but they all have a certain degree of antitoxicity and rejection...... So I think these things should be anesthetized first, so as not to hinder the conduction of the bead energy in the blood. ”

"Something unknown in the blood?" Ota looked at him as if he didn't understand.

Gu Lan nodded, "Yes, because the kind of thing has life and can repair itself, so when you are injured, it will gradually grow and heal." ”

"That's true. Orta nodded, and at this point, there was no change in the bottle, and Guran began the next step of the experiment.

He picked up a metal plate, which was two feet long and two feet wide and only three fingers, with a magic bead inlaid at one end and a pit at the other end.

"This is obsidian, some people also call it the blood demon stone, no matter ****, as long as there is blood splashed on it, it will emit a red light, the more blood it is, the brighter it is, it is said that some are also placed in those ice sculpture bases in the city-state. Guran said casually.

Orta picked up the obsidian and looked at it carefully, and when Gu Lan saw this, he didn't stop it, but took out a few more and set them aside and began to arrange them.

The obsidian leather surface seemed to be polished, and it felt very hard when he pinched it with his hand, and Ota lost interest when he knew that this thing was very common.

At this time, Gu Lan Zhengse said: " This experiment assumes that I have been thinking about it for more than two years, and I should have six or seven points of certainty, first pour blood into the pit and put it into obsidian, the stone can emit light, and then drip blood on the magic bead, because the magic bead is devouring, and this drop of blood is naturally far from enough after it is absorbed, so it will release its own energy to find it, when this energy touches the blood and obsidian in the pit, the obsidian will be brighter, and the time when the magic bead uses energy to find blood, is that I want to observe the speed of its conduction...... I hope it works. ”

Ota nodded, "Since it's an experiment, of course, we must be prepared to fail, but if we don't try, we never know if we can succeed, so it's best not to think about the result, but to do it without regrets in the process of hard work." ”

Guran nodded heavily, and poured a bottle of blood marked as a flaming rat into the pit and placed obsidian, and the stone bead immediately shone with a faint red light. Gulan then dropped a drop of blood on the bead at the other end, and then the two of them quietly observed.

The blood on the orb slowly flowed downward, and Ota and Gulan saw that the blood was flowing at the same time, and it was slowly disappearing, and after two breaths, it actually coagulated, and the next moment it became a dry stained crust and curled.

At the same time, the surface of the metal carrier seemed to condense a mist-like ripple, in the line of sight, the metal surface was actually a little distorted, and the mist-like energy fluctuations also began to roll forward, after five breaths, the entire metal surface was already covered with such mist, and the obsidian also suddenly brightened up at this time, more than ten times brighter than when it was immersed in blood.

"It's done, it's really possible, haha, my idea is so great......" Guran laughed.

Ota congratulated him a few times, and then he jotted down the name of the metal and the duration of its conduction in his notes.

After changing a metal plate, he continued the experiment in the same way, and after a round down, Ota picked up the test notes and said: "The fastest conduction speed is Ugin, followed by the copper mother, and the third is Softsilver Fifth Darkiron...... The eighth is the red steel, and the last one is...... Iron Spirit?"

Seeing this Ota was also stunned, he didn't sort it when he remembered it, and after reading it out one by one according to the length of time of conduction, the iron spirit was actually ranked last.

Gu Lan nodded, and said without surprise: "The front ones are all rare high-quality metals, and there are very few in the territory of the human race, once it is found that such a vein is either controlled by the royal family or disturbed by orcs, it cannot be mined at all." ”

Of course, Ota knew these things, and the four princes could naturally hear what he often said, so he said with some pity: "Yes, in my opinion, a good vein is not exchanged for a city-state, and the saddest thing about being a forger is that there are no good materials to use......

Gu Lan smiled after seeing his compassion for others, and suddenly remembered something and said: "You wait, I have a diary that you may be interested in......" Before he finished speaking, he walked out, and after a short time, Gu Lan came back with an old diary and said:

"This diary belongs to an old friend of mine, who passed away two years ago...... His descendants knew that we were on good terms and gave me this diary as a souvenir, and I found it inside. ”

After turning dozens of pages, Guran pointed out to Otta, "Seven hundred miles southwest of the city-state of Bannaya, a mountain resembles a saddle, and at the foot of the mountain there are red stones of different sizes, and occasionally bright lights flash very much like metal, and it is suspected that there are mineral veins, but because of the ravages of violent beasts, they fled in a hurry after looking at it from afar......

"Bannaya City?" Ota heard the name and immediately remembered that Harvey Naqoura's conjecture had mentioned it, so he quickly glanced at the date behind it.

Although it was not the same person, the date recorded was thirty years ago, and Ota couldn't help but laugh.

Guessing what he was thinking, Güran said, "My old friend is an extremely serious man, and he never preaches anything that he is not sure about, so he certainly did not say anything about it." But whether there is a vein there or not, and whether others have found it, is not known, in fact, it is very simple, just ask if there are any veins mined near the city of Bannaya...... If you can be sure that there is a mine there and no one has found it, then your chance to turn over is here. ”

Ou Ta nodded, and also expressed his gratitude to Gu Lan for his kindness, although Gu Lan's words were not explicitly stated just now, but Ou Ta knew that Gu Lan wanted to use this matter to help him turn over in the Four Princes, if it was determined that there was really a mine there, as long as he provided this clue to the Four Princes, it should not be a problem to restore the title of Baron.

Of course, Gu Lan didn't know that Ou Ta was actually the servant of the four princes, and the relationship between the two was not as simple as Gu Lan thought, but he was still very grateful for Gu Lan's kindness. (To be continued.) )
