After hearing Yang Kai’s question, Yang Yan was stunned, and then he covered his little mouth and smiled and trembled, leaning forward and backward.

"What are you laughing at?" Yang Kai was depressed.

Yang Yan kept waving his hands, but he still couldn't stop smiling, and tears came out of the corners of his eyes.

Yang Kai rolled his eyes and asked again: "Then you are proficient in beauty care. In fact, you are not as young as you appear on the surface, but an old woman who has lived for thousands of years?"

Now Yang Yan seemed to be a cat with a trampled tail, and stopped smiling. His beautiful eyes glared at Yang Kai fiercely, and bit his silver teeth and said, "I can answer you, I am definitely not an old woman who has lived for thousands of years!"

"That's right..." Yang Kai nodded gently. If Yang Yan had really lived for thousands of years, then her experience would not have been so simple. Judging from the various things she had contacted with Yang Yan before, she did not live as long as she had lived.

Yang Yan's expression became serious. He didn't know what he was thinking, but a look of horror appeared on his face. After a while, he spoke: "Are you trying to ask, did I take over this body, right?"

"Yeah." Yang Kai nodded calmly. Only by being taken over could he explain why Yang Yan was not old, but he was proficient in the two mysterious ways of refining weapons and formations.

A person's energy is limited. Although Yang Kai has a great attainment in alchemy, he can't have much energy to study other things by himself unless he gives up his own path of cultivation.

However, Yang Yan has great achievements in weapon refining and formations. The secret treasures she refines and the formations she arranges are far beyond the overall level of the Dark Star in terms of exquisiteness and practicality. How did she do it?

There are many geniuses in this world, but even if Yang Yan is genius, her age is impossible to reach this level, so Yang Kai asked this question.

"Did you doubt it a long time ago?" Yang Yan asked looking at Yang Kai.

"Since I knew you were a master of formations, I have thought so, but don't worry, no matter whether you took over the body or not, it has nothing to do with me. What I know is the soul in your body, and I don't care about the previous soul." Yang Kai said lightly.

Yang Yan smiled bitterly, remained silent for a while, and said softly: "It's not just that you have doubted this way, I can't understand sometimes... But I don't seem to be taken over, because from my childhood memories to my current experiences, I have all existed in my mind in a slight way, and there is no second person's thoughts. If I'm taken over, it's impossible."

"Then which master did you join, so you are proficient in refining weapons and formations?" Yang Kai was shocked. He had no doubt about Yang Yan's words.

Yang Yan shook his head slowly, bit his red lips lightly, his little hands stirred his black robe with some anxiety, his face was hesitant and struggled. After a while, he suddenly raised his head and said in a deep voice: "If I tell you, the reason why I know weapon refining techniques and formations is because I am born to know, do you believe it?"

"How is that possible?" Yang Kai looked shocked.

Yang Yan smiled bitterly: "But that's the truth. I really knew these things by nature. These artifacts and formations seem to be sealed in my mind. As I continue to refine secret treasures and arrange formations, these sealed knowledge are slowly unsealed, allowing me to learn more and more mysterious artifacts and formations. Moreover, sometimes, I see some rare things that I have never seen before, but I can recognize them and know their functions. Is it strange or not?"

Yang Kai was stunned when he heard this.

This is more than just strange, it is simply incredible. No one is born to master the methods of refining weapons and formations for no reason. There must be some reasons, and even Yang Yan himself may not be able to figure out these reasons.

I'm afraid it's precisely because of this reason that Yang Yan himself sometimes feels panic.

There is no need for Yang Yan to lie to herself, and she should not lie.

Yang Kai couldn't help with this kind of thing. Although he had known that Yang Yan was a little strange for a long time, he didn't expect that she was so weird that she didn't continue to force her on this issue. For Yang Kai, no matter whether Yang Yan was taken over or not, he was born to understand some areas that others would find difficult to master for the rest of his life. He only knew Yang Yan now, that's all.

After pondering for a while, Yang Kai asked, "Then what secret treasure can you make now?"

"The virtual level top grade should be fine. As long as I have a lot of materials to practice, I can refine the virtual king-level secret treasure sooner or later." When talking about my own field, Yang Yan suddenly recovered a lot of energy, and looked proud.

"Okay, help me refine this." Yang Kai took out the purple shield with an awkward look.

The originally flowing shield of purple rhyme is now dull and has lost its spirituality.

When Yang Yan saw this, a look of worry appeared on his pretty face. He picked up the shield and stroked it gently, and said, "Did you encounter any fire-attribute ban? He actually beat the mid-level defensive treasure like this with just one blow."

"Yeah, but it's finally a disaster." Yang Kai grinned.

"I understand. With the materials you gave me, it should be fine to refine them into virtual-level top-grade secret treasures." Yang Yan's space glow flashed, and the purple shield was taken in by her. She stroked the hair in her ears and returned to her former spirit. The beautiful eyes were filled with joy and said, "What good things did you get this trip? Take it out and I'll take them out and take a look."

"Wait!" Yang Kai nodded and searched for it in his space ring. There were quite a lot of good things he got this time. He called Yang Yan here just to let her see some things. Yang Kai didn't know what they were for.

Soon, Yang Kai waved his hand and emitted a piece of burning fire aura, red crystals that were all red, the size of a millstone appeared in front of the two.

"This is..." Yang Yan's eyes immediately burst into a different light, and his expression was attracted by the fiery red crystal.

"It should be a fire crystal stone!" Yang Kai touched his chin, "It's just that I don't understand why it is so big, and my experience of getting it is also very strange. It's not obtained from the body of the fire spirit beast..."

At that moment, Yang Kai briefly explained his experience in the strange valley, and this huge fire crystal stone was also his first harvest when he entered the Liuyan Sand.

Yang Yan kept staring at the fire crystal stone while Yang Kai was talking about these things, and one hand was still gently stroking it.

After Yang Kai finished speaking, Yang Yan nodded and said, "It should be that the fire crystal stone is right, but this fire crystal stone has its own formation, so it can inspire the fire elf and form various fire spirit beasts to prevent your progress."

"The internal formation?" Yang Kai's expression moved, but he didn't notice this.

"Well, it's a natural and mysterious formation." Yang Yan smiled pursed his lips, "This thing is useful, but if it is used to refine weapons, it's a bit constrained. Give it to me, it can be used to arrange a formation. That formation requires such a thing as the array eye."

"Okay." Yang Kai nodded, not stingy, and waved his hand readily and sent it out. Anyway, Yang Yan set up the formation to protect Longxue Mountain and he could also benefit himself.

"What else?" Yang Yan put the huge fire crystal stone into the space ring, and his beautiful eyes stared at Yang Kai without hesitation for a moment, as if he was looking forward to it.

"This!" Yang Kai reached out and took out a blood-red thing. The thing looked a bit like a grass seed, but it exuded a strange bloody aura.

"The seeds of the Blood Sword Grass!" Yang Yanyou suddenly lost his color when he saw this thing and exclaimed.

She actually recognized the seed as soon as possible.

"The Blood Sword Grass... is quite worthy of its name." Yang Kai nodded thoughtfully, recalling what he had experienced after falling into the strange maze. When he broke the shackles of the formation and walked out of a passage, there were many red weeds on both sides, growing wildly as if they were alive, turning into attacks and attacking him.

Moreover, the blood-red weeds are indeed extremely hard and sharp. Even with Yang Kai's strong body, they dare not let them cut at will.

"There is such a thing in Liuyan Sand." Yang Yan's face turned a little pale.

"Is this thing very famous?" Yang Kai couldn't help feeling a little strange when he saw her looking like he was facing a great enemy.

"I don't know whether it is famous or not, but I know its horror. It can grow infinitely. As long as there is enough flesh and blood for it to absorb, its power will continue to become stronger and grow to its limit. Even the body of the Void King Realm can block its cutting."

"So scary?" Yang Kai was startled, and in an instant he felt a little scared and grateful.

If Yang Yan said it was true, the blood sword grass he encountered should not have grown up, otherwise he would not have no choice but to do anything to him.

"This thing was famous in ancient times. Many sects and forbidden areas were planted to protect it." Yang Yan gently pinched the blood-red seed with a cautious look.

"What a pity, there is only one seed, if there is a little more..." Yang Kai not only did not fear, but felt regretful.

"What a pity?" Yang Yan sneered, "Not a pity at all. One grain is enough. The Blood Sword Grass can reproduce and grow by itself. As long as there is a seed and gives it enough flesh and blood, it can reproduce."

Yang Kai's eyes lit up when he heard this.

"What do you want to do?" Yang Yan seemed to notice the dangerous aura flashing in Yang Kai's eyes, and his heart suddenly burst out and asked hurriedly.

"What are you not doing?" Yang Kai smiled, took the seeds of the Blood Sword Grass from Yang Yan's hand and carefully collected them himself.

"I'll tell you first. If you want to plant it, you have to say it to me in advance, but don't worry too much. As long as you don't provide it with flesh and blood, it won't grow and it won't be harmful."

"Well, I understand." Yang Kai nodded and took out two things from the space ring.
