"Let's try again!" Lin Xiangnan continued.

"Not true. Han Jue shook his head, "You should find out what went wrong first, otherwise it will be useless to try again." ”

One by one, the researchers came over, holding a large stack of books, and said: "This kind of thing has never happened before, and there are only a few records in some classics. He placed the book in front of everyone, dozens of centimeters thick, "There is a case here that may help you a little." ”

"So many books...... Lin Xiangnan was speechless, "It hurts my head to see it." ”

"You haven't seen it yet!" Han Jue reminded.

“......”

"That's probably why. Hyacinth picked up a book and pointed out a paragraph of text to Lin Xiangnan, "If the secret card wants to be used, it needs to be completely activated by spiritual power, and the secret card that has been torn in half in history needs to have a resonance if you want to use it." ”

"Then experience the empathy. Lin Xiangnan stood up and patted his buttocks, "I'll use it first, you can see how to find resonance." ”

After that, Lin Xiangnan closed his eyes, different from the normal use of secret cards, the difficulty of using mental power to communicate with this half of the king's teeth has obviously increased a lot, Lin Xiangnan tried many times, and finally succeeded in making the secret cards release a golden light in his mind.

"It's coming. Hyacinth's eyes flashed with a glimmer of light, she hadn't used her mental power to communicate, and the other half of the secret card in her brain had begun to emit a dim light, although it was not strong, but this was indeed a precursor to the secret card to be used.

"Secret card!

Hyacinth faintly pronounced its name, and at the same time, Lin Xiangnan instantly felt a dizziness in his brain, and his spiritual power seemed to be drained by this half of the secret card at once.

This has never happened before.

When he stabilized his mind again, he was surprised to find that a blurred light appeared in the mutilation of the half of the secret card in his mind, which gradually condensed into a shape, and at first glance it looked like this half of the secret card had been repaired.

A thick black mist erupted from Hyacinth's slender palm and condensed into a huge black mist in front of the crowd, which at first glance looked like a pair of dark clouds.

The "dark cloud" gradually struggled and twisted, and the surface began to become uneven, like an embryo, and after a few seconds, the "dark cloud" Mougins exploded, and a pitch-black shadow jumped out of it.

"Wang Ya!" Han Jue was overjoyed, he didn't expect Lin Xiangnan and Hyacinth to really be able to use this secret card.

"Try to command it. Han Jue then said to Hyacinth and Lin Xiangnan.

"Hmm. The two nodded, and then in a thought, Wang Ya changed again, from the middle of its body, a gray line suddenly appeared, and the right half of Wang Ya's body also turned dark gray, in sharp contrast to the black on the left.

The crowd was not stupid, and almost immediately understood the current situation.

Lin Xiangnan tried to let Wang Ya stretch out his palm, and sure enough, the gray body on Wang Ya's right stretched out its forepalm.

Hyacinth did the same, but this time the king's tooth was sticking out a black left claw.

"It seems that the two of us can only control one side of our bodies. Lin Xiangnan nodded and said thoughtfully.

"That's not bad, it's better than having this secret card go to waste. Hyacinth tried to control the other half of King's Tooth, but to no avail.

Wang Ya is like a toddler, his left and right bodies are extremely uncoordinated, and it is even difficult to walk, which is of course the phenomenon caused by Lin Xiangnan and Hyacinth's lack of cooperation with each other when he summoned it for the first time.

After the two practiced for a while, Wang Ya's movements finally became a lot smoother, Han Jue was a little surprised, after all, it was extremely difficult for two people to control a body, but Lin Xiangnan and Hyacinth were very surprised that they had adapted to each other so quickly.

"Isn't this secret card supposed to be called the Nine Tribulations, and how did it become a king's tooth again?" asked a researcher curiously

"Because the Nine Tribulations are the embodiment of the king's teeth. Lin Xiangnan explained to him, "Before, this secret card was divided into three, collectively known as the Nine Tribulations, but now that it has been integrated, it has become a king's tooth." ”

"Use your king's fangs to attack the puppet as best you can outside the red line, and let me see the details of this secret card. Han Jue said slowly.

"Understood. ”

The two of them agreed, walked beyond the red line on the ground, and concentrated on controlling the secret card in their minds, and in the blink of an eye, clouds of black smoke emerged, and as their breathing surged more and more violently.

Not to be outdone, the doll glows red, and it doesn't seem like it's a toy that only gets beaten.

The crimson firelight illuminated Hyacinth's face.

"Leave you!" Lin Xiangnan said.

With a wave of one hand, Wang Ya slashed through the space as if he had received an order, and flew towards the metal puppet with a fierce momentum, drawing a strange black mist tail in the air.

With a pop, the moment the black mist touched the puppet, it suddenly burst open, and the black clouds scattered, weird and exaggerated.

The black clouds churned, completely engulfing the puppet after a few seconds, and strangely, the other people's eyes could not penetrate the black mist.

"The body is rotten!" Hyacinth said lightly.

The black clouds dissipated, and the surface of the originally smooth and sturdy puppet had become pitted, as if it had been corroded by a strong acid liquid, and a staff member only touched it lightly, and the puppet immediately turned into a puddle of solid-liquid mixture.

"Isn't this two of the nine tribulations?" Han Jue was a little surprised, it seemed that Lin Xiangnan and Hyacinth could control the spread of the nine tribulations through the king's tooth.

"All nine difficulties can be used. Lin Xiangnan said, "And the two of us can also control it." ”

"Let's test your control distance. Staff member B said.

"What do you mean?" Lin Xiangnan scratched his head, "I didn't understand." ”

"Doesn't this secret card need the two of you to use now?" Staff Member B patiently explained, "I want to test whether you two can continue to use it the way you are now, after a certain distance apart." ”

"Yes, that's important. Han Jue also looked at them seriously and said.

"How to measure?" Lin Xiangnan asked, "Do you need the two of us to be separated by a certain distance?"

"Yes. Staff B nodded, "But the lab is too small, so let's go to the arena in the South Wind Academy, which is the largest venue in the school." ”

"I don't know. Lin Xiangnan smiled awkwardly.

"That arena is on the roof of the Nanfeng Academy's teaching building, and it's several kilometers in size, so it should be enough for testing. Han Jue said, "By the way, find someone to fight and see how much strength the two of you can exert in the wind rank of the king's teeth." ”
