The old man worked intently, and Li Yan was watching quietly. Neither of them cast magic that could illuminate. In the dark room, there was only the "click" sound of the carving knife slashing on the stone slab, mixing the gloomy and dead energy that was already there in the tower, how terrifying it sounded.

Time passes slowly, and I don’t know how long it has passed. A pattern drawn by a knives is gradually taking shape, and the lines with smooth curves are complicated and intertwined together, but they look like three-dimensional, making people understand the direction of the lines at a glance. However, if you look closely, it is like a mess and you can’t see the beginning and end. Over time, it makes you dizzy and weird.[]

Suddenly, under the control of the old man, the knife slowly cut down on the stone slab towards the old man's body. This stroke was like a meteor hanging across the sky, stunning, and reflected in Li Yan's visual network, a kind of terrifying kill came to his face!

At the same time, the old man's left hand was no longer clumsy. He controlled the magic pattern engraving stroke and picked up the purple magic engraving potion and printed a purple track with the tail marks of the meteor.

Immediately afterwards, a golden light visible to the naked eye passed by along the pattern on the stone slab from beginning to end, and the magic array was engraved.

When the old man put the engraving knife and the magic pattern engraving pen in his hand back into the knife box, in the pen groove, Li Yan's eyes were still staring at the stone slab in front of him. The runes engraved on it corresponded to every pressing of the engraving knife, and the twists were played back and forth in his mind. One by one, the actions were analyzed and combined with the theoretical knowledge in the book.

The old man did not disturb him, and he still stared straight ahead with his hands hanging down.

After a whole minute, Li Yan came to his senses and buried some doubts that could not be solved for the time being in his heart. He raised his head and exclaimed at the old man: "Your seal is so wonderful, it's simply art!"

"No, this is just a inferior product." The old man's answer was faintly angry, "The depiction speed is too slow, and the magic elements are not fusion enough. Although it can be used, the effect is much worse, hum!"

Not wanting to bother with this issue anymore, the old man turned his head and laughed at Li Yan, "Are you ready?"

"Yes, if you are referring to the test of basic portrayal of magic circles." Li Yan nodded slightly and said with a smile, "Your collection is very rich, allowing me to learn a lot of knowledge."

He looked at Li Yan with an interesting look. The old man staggered his back and walked towards the other end of the obsidian table. "Hehe, he is still so confident, this is very good. Explain the Bondal formula."

Li Yan replied without hesitation: "Bondal formula, the formula summarized and calculated by the alchemist Bondal in 1356, 1356, is a very useful basic technique to calculate the depth and width required for each arc segment through the overall proportion of the magic pattern and the energy intensity of the magic pattern.

"I didn't ask you to say these boring things, explain the calculation method and specific principles!" A hoarse, dead white voice came from the old man who was still facing away from Li Yan, "Well, compare this rune to analyze."

He caught the elliptical stone as big as a palm that flew out of thin air, put it in his hand and checked it out in a general way, and Li Yan began to explain in detail.

His words "more troublesome" are indeed correct. Although Li Yan was as smooth and natural as he could do it during the explanation, by the time he had already passed by more than ten minutes.

The old man who had already stood on the other end of the obsidian table quietly listened to Li Yan's explanation, and his tone of dying voice finally changed: "Yes, it was a bit beyond my expectations to be able to skillfully use the Bondal formula in three days. It seems that you are worthy of your confidence."

"Thank you for your praise, but unfortunately, this is just theoretical knowledge." Li Yan said.

"Don't show your modesty in front of me. I just look at the facts and actually I have prepared the recovery potion." The old man showed off the miniature crystal flask containing the purple potion in his left hand, and swayed slightly and smiled, "Hehe, it will make your body extremely resilient when it is roasted by the Nether Fire, but it will increase a little numbness and it will amplify a little pain."

Looking at the old man's strange look of expectation, Li Yan's eyelids twitched slightly. If he believed that what the old man said was just a little bit, he would be a fool, fortunately he didn't find an excuse.

"Then there is only one last problem left now, well, it's not actually a problem." After taking back the recovery potion, the old man turned the corner of the table and walked towards Li Yan, "Look at this."

A pink oval gem nearly an inch long in the outstretched right hand was shining in the darkness. The pink light seemed to be mixed with light gold tassels, which actually exuded a dreamlike charm that could suck human souls in!

At this moment, even Li Yan was deeply shocked. No one could refuse such beauty. He couldn't help but murmur: "What is this?"

"The tears of Aphrodite, the legendary gift of the God of Love, disappeared with the disappearance of the magical sorceress Meiluo before the 6th calendar." It seemed to be talking about the most ordinary item. When he walked in front of Li Yan, the old man rolled the gem and recorded it without hesitation.

He looked up and said, "You are lucky that this thing is of no use to me, but through it I can enter your spiritual world and restore the process and feelings of my magic circle to let you experience it. This experience is like you are personally carving the magic circle, very clear and intuitive.

It is enough to give you rich experience in magic circle portraying in an instant. You just need to penetrate the mind power into this stone without resisting it."

Faced with the almost irresistible temptation in front of him, Li Yan's brow suddenly jumped as he turned his mind: "I have some doubts."

He stared at Li Yan silently for a few seconds, and the old man nodded.

"First point, I can have experience in portraying magic circles, but will I be equally proficient in actually doing it?"

"No." The old man took back the gem and shook his head, "actually, taking action requires a double cooperation between the body and consciousness. This cannot be done without training, but having experience in consciousness in advance will speed up the process of this training."

"So, the second point." Li Yan stared at the old man's turbid eyes, "Can you enter my spiritual world let you see my past?!" The last word "go" was decisive!

Faced with the questioning, the old man waved his left hand and said in a deep voice like anger: "This is not what you should ask! The only thing you can do is accept my gift!"

"No! This is not a gift, but a confinement!" The rebuttal burst out like a torrent of breaking the dam, hitting the wall and causing huge waves. The old man's face changed suddenly!

"court death!"
