In the quiet tomb hall, only the breathing of three people could be heard.

Under the faint light, the original golden shield was now dull, as if it could collapse at any time.

Shen Yun, who was sitting quietly, suddenly opened his eyes, stood up suddenly, a faint smile flashed in his eyes, and walked towards the golden magic circle with full energy.

Shi Qiulan's sister and brother immediately sensed it, stood up almost at the same time, and looked at Shen Yun with a smile.

The ban was cast, and the brilliance flashed.

Immediately afterwards, there was a soft "click", and the golden light mask directly collapsed, cracking like a blister, turning into a little starlight, and disappearing, obviously the aura in the formation had been exhausted.

Everyone looked at it and saw a basin-sized, octagonal brown compass-like object left on the ground, with eight small flags planted on it.

"Hey, is it the array plate?" Shen Yun snorted softly, his face was incredulous, he took a few steps forward in surprise, squatted down to take a closer look, and thought it was only the array flag.

"It really is. Shi Qiulan also looked at him with a strange look and muttered.

The three of them took a few steps closer and looked at it carefully.

This octagonal object, the surface of the grain is engraved with many simple lines, which appears uneven, and the power is faintly introverted, and you can know that this thing is extraordinary at first sight.

The eight rounded outer edges are as smooth as a mirror, and in the middle of each side, there is a round hole, and each has a small flag of different colors, except for a red one that has not been seen, the rest of the seven array flags, Huo Ran flew out behind the previous doors.

A little inward, there is another circle of eight grooves, just like the hole at the top of the eight-pole flagpole, there are only some spirit stone fragments left.

"Does this mean that this array plate and array flag need sixteen spirit stones to activate?" Shi Jin silently counted and asked curiously.

"The array flag can be arranged alone, and eight spirit stones can do, but the power is poor. Shen Yun was in a very good mood and said with a smile, "If the array plate and the array flag are arranged together, at least eight pieces will be required, and they can be inlaid on the array plate." ”

Suddenly looked at Shi Qiulan and asked, "By the way, how many spirit stones do you need to open that mountain protection array on Ling Peak?"

"That's a lot, a hundred and eight dollars. Shi Qiulan sighed when she heard this, "And it can also be activated by one hundred and eight medium-grade spirit stones to increase its power." ”

"So powerful!" Shen Yun gasped, more than a hundred medium-grade spirit stones, that is, more than 10,000 lower-grade spirit stones.

Spirit stones are divided into low-grade, medium-grade, high-grade and superb.

The spirit stone that everyone usually talks about usually refers to the lower grade spirit stone.

Spirit stones are the common currency of immortal cultivators, generally medium-grade spirit stones are equivalent to one hundred lower-grade spirit stones, and one high-grade spirit stone is equivalent to one hundred medium-grade spirit stones......

In fact, there are only low-grade spirit stones and medium-grade spirit stones circulating on the market, and high-grade spirit stones only exist in legends, and the best spirit stones even exist in this world.

"What a waste. It was the first time Shi Jin had heard about the Mountain Protection Array, and muttered.

"If you want to waste it, you can't do it, how can there be so many medium-grade spirit stones. Shi Qiulan shook her head helplessly, and she didn't have a good airway.

Shi Jin sneered, and then pointed to a hemispherical groove the size of a baby's fist in the center of the array plate, and asked, "Brother Shen, what is this?"

Shen Yun squatted not far from the array plate, and looked along Shi Jin's fingers, only to see the concave surface in the middle of the array plate, like a shallow hemisphere dug out, which was engraved with many ancient and vigorous spirit patterns.

Shaking his head slightly, he said: "This is not clear, but the original fangs magic weapon should be placed here." ”
