As soon as he entered the door, Feng Qianyan was stunned for a moment, and the second uncle Feng Rui was also there.

"Grandpa!

"Yan Yan, come here, sit here. Although Feng Xiaotian still has a kind face, he is a little more serious now.

"Grandpa, you're looking for me-" Feng Qianyan glanced at the second uncle, Feng Rui bowed slightly, "The second uncle told you?"

Feng Xiaotian nodded: "Hmm." When it comes to washing the marrow, Yan Yan can decide for herself. But it's not for that now. ”

"That's ——?"

"Take you somewhere, come with me. ”

After saying that, Feng Xiaotian took his granddaughter to the bedroom, while Feng Rui stayed in the study. The old man walked to the side and groped for a moment, and the secret passage above the wall opened again.

Since he had gone down with Feng Heng once before, Feng Qianyan followed Feng Xiaotian with ease and walked down the secret passage.

"Grandpa, what are we going to do in the secret room?" Feng Tianyan was a little curious.

"You'll find out later. ”

"Oh. The wind pouted. Alas, one or two of them are so mysterious.

In the center of the underground chamber, there is still a test bench, and nothing has changed.

Wind Howling walked over to an iron door, took out a strangely shaped jade plaque, placed it in the groove on the door, and began to turn a compass-like mechanism clockwise below.

The first feeling of the wind is like a combination lock on a modern safe!

After a while, only a "click" was heard, and the wind whistled to stop moving.

"Yan Yan, remember these three patterns. Old Man Feng pointed to the pattern on the compass facing the pointer and said.

"Remember!" Feng Qianyan nodded, just three patterns, for his memory, it was too pediatric!

"Let's go inside. Feng Xiaotian said, took the jade plate, and pushed open the iron door.

As soon as the two of them entered the house, the heavy iron door began to slowly close. After the iron door was closed, Feng Qiyan heard a "click" sound of gears turning, and when he turned around, he found that the inside of the iron door had the same grooves and compass as the outside.

Walking into the room, Feng was stunned, except for a small platform in the center of the room that was half a person high and a foot square, it was unexpectedly empty, and there was nothing.

Feng Qianyan walked to the stage and found that a complex formation was carved on the table.

"Formation, grandpa, is this?" Feng Qianyan pointed to the platform and looked at the wind howling sky.

"This is the teleportation array. ”

"Teleportation Array?" Feng Qianyan had never seen such a thing before, so he couldn't help but be very curious.

Feng Xiaotian took out five white stones the size of pigeon eggs, and patiently explained: "This is a low-grade spirit stone, the distance we go is not too far, these five low-grade spirit stones are enough." If the teleportation distance is relatively long, or the number of people is large, it is necessary to draw a larger and more complex teleportation array, and when it is opened, a larger number of spirit stones will be required, or even a large number of high-grade spirit stones. ”

After speaking, the five spirit stones were placed in different positions, and the formation was suddenly golden.

Feng Xiaotian took his granddaughter in his arms, stood in the golden light, and admonished, "Don't move." ”

"Got it, grandpa. Feng Qianyan stretched out his little hand and grabbed the placket of his grandfather's clothes tightly.

"Grandpa, are spirit stones expensive?"

"A low-grade spirit stone costs about 50,000 taels of silver. ”

The master's answer was very bland, but Feng Tianyan couldn't help but be stunned when he heard it: It costs 250,000 taels of silver to open it once, and it is still a small teleportation array, which is really a burning of money!
