At the moment, it''s not only he and Ji Ning who are in the back garden, but Shangguan and Zixuan are also there. Obviously, Shangguan just called her over. Their speed is much faster than Chen Jianfei''s.

    What surprised Chen Jianfei was that it was not these people in the backyard, but what they did.

    Tang Feng is standing in the middle of the open space in the back garden. At his feet, there is an antique mirror.

    This mirror is placed upward, that is to say, toward the sky. On the mirror, there is a small rectangular jade plate about the size of a lighter.

    Chen Jianfei''s eyes are very good. Even from a certain distance, he can clearly see the patterns carved on the jade plate. It looks like some words he doesn''t know. When Chen Jianfei sees these words, the first thought in his mind is rune.

    This is almost the same as some of the symbols painted on yellow watch paper. However, Chen Jianfei didn''t know much about it, could not see any difference, and was not sure. They were the same.

    According to the truth, the mirror is facing the sky. Inside the mirror, blue sky and white clouds should be reflected. But Chen Jianfei is looking at the dark inside. Even on such a sunny day, because of the angle problem, Chen Jianfei can''t see the mirror reflecting the sky, but he can''t see only a dark cloud, can he?

    However, this is far from the reason why Chen Jianfei was surprised.

    What made him feel puzzled was that Tang Feng was standing in that position with his shoulders in his hands. His whole body was still except his lips were moving slightly. He looked like a statue.

    Chen Jianfei was sure that although Tang Feng''s lips were moving, he didn''t make any sound. Otherwise, with his ear power, he would be able to hear it at such a distance.

    Tang Feng moved his lips silently. Chen Jianfei couldn''t hear it, but the other three people seemed to be able to hear it.

    They are surrounded by Tang Feng and form a circle outside. The reason why it is a circle is that they are moving along the shape of a circle.

    In other words, they take Tang Feng as the center of the circle and circle.

    Of course, it''s not just a circle.

    Chen Jianfei saw that in their hands, they were holding several small jade plates, which were almost the same as those on the mirror. However, Chen Jianfei felt that the patterns on them seemed to be different.

    After all, Chen Jianfei is a long way away from them. No matter how good his eyes are, there is no way to tell the difference between the patterns of the small jade brands in the hands of the three people in a short time. It''s just a vague feeling.

    These three people, while circling, with some inquiring eyes, look towards Tang Feng. From time to time, there will be a person who throws out his little jade card.

    It seems that these three people are following Tang Feng''s order to throw out a small jade card, but Chen Jianfei can''t hear Tang Feng''s voice.

    Tang Feng was silent, and the other three were silent.

    In such a quiet atmosphere, Tang Feng stood still and seemed to recite incantations. Zixuan and other three people circled around him. Moreover, the look on their faces was also a bit strange. The corners of their mouths were slightly up. In their eyes, they were excited and seemed to suppress their inner joy.

    But their faces looked happy, but they didn''t show any more happiness. They didn''t even speak. They just mechanically threw little jade cards, which was quite strange.

    After observing for a while, Chen Jianfei found that what they threw was not in the same direction, but in a regular way.

    Every time, Ji Ning throws the small jade card in the air towards Tang Feng, while Shangguan throws it in the vertical direction above her head. The strangest thing is Zixuan. She throws the jade card at her feet.

    Of course, these alone are not enough to shock Chen Jianfei, who is also well-informed.

    Among all these things, what makes him feel most incredible is that the little jade plate thrown into the air by Ji Ning and Shangguan didn''t fall down, but flashed and disappeared.

    Because it''s day time, and now the sun is shining, the flicker seems insignificant. Chen Jianfei is almost not sure whether it''s really flickering. The little jade brand is just missing out of thin air.

    The little jade plate that Zixuan threw at her feet was the same. It seemed that all of a sudden, it got into the soil.

    Chen Jianfei looked at all this in a daze. Some couldn''t believe his eyes. He couldn''t help rubbing them with his hands. Then he looked carefully, especially in the air. He wanted to find some clues there. He thought whether they were throwing too fast or flying too high, and he didn''t see the direction clearly, I didn''t realize where the jade cards were.

    However, for these reasons, even Chen Jianfei himself can''t convince himself that as a martial arts practitioner, his eyesight is far beyond the ordinary people''s ability. Can he miss it?

    Chen Jianfei stands here, watching Tang Feng and others'' strange behavior. It''s only a minute or two. Zixuan and others'' little jade cards have been thrown clean. They all stop and look at Tang Feng.

    This time, Tang Feng also had some action. He nodded his head slightly, his face showed a very satisfied look, and finally said: "yes, it''s quite good that you can do it for the first time. If you continue to work hard in the future, you will soon be able to master the key."

    With Tang Feng''s words, it seems that they are in contact with the imprisonment of Zixuan and other three people. They immediately let out a long sigh of relief. Then, everyone is quite excited.

    It can be seen that this is the excitement they deliberately suppressed just now.

    They looked at each other and there was a smile on their faces, and the smile was quite obvious.

    It''s very common for Zixuan to talk and laugh. Shangguan and Ji Ning are both so happy, but it''s quite rare.

    Zixuan''s face beamed and said, "well, well, we will work hard, but we don''t know when we will have a chance next time."

    Looking at the situation, Chen Jianfei''s suspicions added a little more. He finally stepped forward and asked Tang Feng curiously, "Mr. Tang, what are you doing?"

    Tang Feng is still with a faint smile, lips gently open, spit out two words: "array."
