"Teacher Yuhua, don't be angry. Actually..."

Hua Kai was a little worried that Yuhua would be really angry, so she hurriedly stepped forward to explain.

"Shhhh What is it? ”

Yuhua's afterglow aimed at the fragments of the stone platform on the ground, and the magic fluctuations transmitted from it instantly attracted his attention, Yuhua walked over to pick it up and took a closer look.

"Teacher Yuhua, it was this stone platform that interfered with us just now, it controls a bunch of vines, which is particularly difficult to deal with! Later, Sakura thought of a way to make Tisya's fire magic and Jingyin's ice magic constantly switch to destroy it, but she didn't expect the energy contained in the stone platform to shatter and suddenly burst away..."

"Okay, I got it."

Yu Hua stared at the stone platform in his hand, with a very surprised look in his eyes, and even the tone of replying to the blossom was a little perfunctory.

"Teacher Yuhua, do you know this thing?"

Flowers bloom very well depending on the situation.

"If I'm not mistaken, this thing should be a special item for storing mana, look at the patterns!"

Yu Hua patted the surface of the broken pieces of the stone platform as he spoke, but he didn't expect the layer of gray on the surface of the stone platform to fall off, and there were some dark green traces revealed inside, but just this small piece of things couldn't tell what it was.

"Hey!"

Yuhua flicked his finger, and a weak breeze blew in the distant sky, which rolled up the pieces of stone platforms of different sizes on the ground and put them together, and the dirty ash on the original gray surface was also cleaned up by the way.

"What is this?"

Yuhua's eyes were stunned, the thing contained in this stone platform turned out to be a spherical bronze product, which was already covered with a little rust, and there was a thin hole at the bottom, and there was something like a lid next to it, which could be blocked at any time.

"This thing feels like it's been a long time, and it shouldn't look like a product of the elves!"

Sakura had always been curious about this kind of thing, and she walked up to Yuhua's side and examined the bronze orb with a curious look.

"Oh? I know a lot! That's right, this bronze ball is indeed not the work of the elves. ”

"Judging by your tone, it looks like you know the origin of this thing!"

"Hmph, this bronze ball is actually a magic guide for humans to store magic power in order to maintain the abundance of magic power on the battlefield at any time during the war between the human race and the demon race more than a hundred years ago. However, this kind of thing was made of very valuable and rare metals, and it was not produced in large quantities, and it was completely discontinued in the later stages of the war."

"Huh? Discontinued more than a hundred years ago? So why is it here? ”

"That's right, that's what surprised me so much!"

Yuhua gently held the bronze ball on the palm of his right hand, and kept groping with his index finger and thumb.

"Is this..."

Yuhua's eyes lit up, and he found that the surface of the bronze ball actually had soil embedded in it, because of the relationship of time, the soil had become dark, and at first glance it was impossible to see its original appearance.

Yuhua rolled his fingers, and the previous breeze drilled into the gap between the dirt and the bronze ball, and lifted the air-dried soil, thanks to this, the true appearance of the bronze ball was revealed.

Its rusty, spherical shell is covered with numerous stripes, about the thickness of a needle's tip, crisscrossing each other to form a delicate pattern.

Yu Hua transferred the bronze ball in his right hand to his left hand, and his free right hand lightly tapped the space in front of him.

"Wow!"

In the next second, pale golden points of light appeared in the place where Yuhua had spotted, and these points of light rotated and pieced together a shape exactly like the bronze ball in the air.

"What are you doing?"

Sakura watched Yuhua operate unhurriedly with interest, no matter how he said that he was half of Yuhua's "apprentice", maybe what Yuhua is getting now will be of great help to his future research!

"Oh, that's what you said!"

Yuhua turned around and threw the pale golden bronze ball suspended above his right hand at Sakura's side.

"Oh ~ Whew!"

Sakura was caught off guard by the pale golden bronze ball that was suddenly thrown over, but she managed to catch it without any problems.

(This feel··· ）

"That's right, it's just a model made out of magic. In order to study the patterns on this bronze ball, I made something exactly like it with my magic, but of course this is just an empty shell, which you will use more often in the future. ”

After speaking, Yuhua made a bronze ball model again and began to look at it.

"Naa, Tisya. Can you understand what the two of them are saying? ”

Shizune asked, tilting her head as she stood behind.

"I don't know."

"Hmph, I guess you don't know either."

"You know I don't know, and you come and ask me! Aren't you here to find fault? ”

"You've found out!"

The quarrel between the two people in the back really affected his train of thought too much, and Yuhua simply waved his hand and used a silence magic to block the mouths of the two of them. fate

"I see!"

Sakura made a loud noise as she stared at the model in her hand.

"Look! If we expand it around the hole at the bottom of the bronze ball, we can get a lot of things that resemble the shape of an orange petal. And then... Uh~This..."

Yuhua was inspired to follow the method provided by Sakura.

"First put the bottom of the bronze ball up, and then cut it at an angle."

Yuhua is spinning his brain rapidly, while controlling the operation of the model, because the model is made of magic, so it doesn't matter if it fails, just recreate a model if it fails.

"And then I put these things together in the direction of the stripes, and then... Reverse rotation...

Little by little, the bronze ball model in Yuhua's hand was transformed into a disc-shaped thing, and the small hole was its center, and the patterns on it spread over the entire disc like a dense river from the small hole.

"This ...... This is!!!? ”

"Magic Circle?"

As soon as Yuhua raised his fingertips, the disc model in front of him flew into the air, and then zoomed in instantly, so that it was more convenient to observe the details.

Sakura followed behind her, silently staring at the disc, hoping to help.

"This magic seems to..."

"What's the matter, this magic?"

"This magic guide seems to have been transformed, looking at the effect of this magic array, it should be attached to it with the attribute of gestation."

"Fertility attributes?"

Sakura thought for a moment, she had only seen this word once in "Creation Studies", and the specific meaning had not been expanded.

"The gestation attribute is actually a bit like cultivating magic, you have to store the mana in a container, and then apply the gestation attribute to this container, then the mana stored in this container will continue to increase, although the speed is very slow, but if it continues to increase over the years, then it will definitely become a very powerful force in the future."

"Oh, I see."

Sakura casually put her finger against her chin and said slowly.

"But how come I haven't heard of this gestation attribute before!"

"It's normal that you haven't heard of it, this gestation attribute is also artificially designed by humans in the war between humans and demons in order to make up for the lack of combat power on the battlefield, and after the war, it was listed as a forbidden technique because its production was too ferocious. You must know that in order to exert this gestation attribute, you need at least a hundred or so living human hearts as the base. ”

(100 pcs!! ）

Although they didn't understand what kind of things Yuhua and Sakura had communicated with before, Tisya had a concept about these hundred people's hearts.

(A hundred lives!) ）

"You don't really think that this one gestation attribute can be made with a hundred lives, this hundred hearts are conditional, and they must meet the three points of magic of the same attribute, the same age, and similar magic fluctuations, the first two points are okay, do you know how difficult it is to find something similar to magic fluctuations? It's hard to find anyone with similar magic fluctuations among at least 10,000 people. ”

"This ······"

Everyone didn't know what to say at this time, they believed that Yuhua would not lie to themselves, but these things that their race had done would not be erased, except for Lalisi, the other four people actually had a sense of shame as a human race at this time.

In the same way, Yu Hua dismantled the body of the bronze ball, and he wanted to see what was worthy of cultivating the breeding attribute.

"Click!"

With a crisp sound, a square popped out of the bronze disc, which was also made of bronze and completely sealed, and it was in it that the magic was stored before it was conceived.

Yuhua opened the square, but what he didn't expect was that the square was empty, and there was no magic at all.

(Huh?) How is it empty? Could it be that there is no mana stored in it, or is it ······ The magic inside has leaked out? ）

Yuhua looked around, the sky was black and oppressive, it was about four o'clock in the morning, it stands to reason that the sky should be a little bright at this time, and there was this sharp wind flow, each of which was cold and biting, this kind of vision definitely had a great catty existence.

"Teacher Yuhua, what are these black magic particles!?"

Because of the heterochromic pupils, the blossoms can see the black magic particles seeping out of the sacred tree.

"Black magic particles... Not good! Remove the Evil Eye! ”

Yuhua's face changed, and an ominous premonition surged in his heart, he closed his eyes and quickly opened them, the demon eye can be understood as a weakened heterochromic pupil, but Yuhua's proficiency in it is much higher than Hua Kai's control of heterochromic pupils, so for now, the effect of demon removal eyes is much higher than that of heterochromic pupils.

Yuhua looked around, the air was filled with swarthy particles, and sure enough, what he was most afraid of still happened!

(Celestial ······ ）

At this moment, the sacred tree under everyone's feet suddenly shook violently, and everyone who was unprepared was thrown into the air at once.

"Qi!"

As soon as Yuhua spoke, a white light appeared from him and sent him to everyone's side, the same white light flashed several times again, Yuhua grabbed the collar of the floating people and dragged them into the space jump, and safely sent them back to the ground.

"Today's training mission has been canceled, you guys wait for me from here, I'm going to take care of the matter at hand."

Yu Hua's expression was a little solemn, and the fifth girl also realized the seriousness of the matter, which could make such a casual person as Yuhua serious, which showed how important the change of the divine tree was to the elf race.
