Chu Xin'er first put away the Spirit Devouring Worm, and then searched carefully, confirming that the black-robed man's Yuan Shen and storage bag had all dissipated in the self-explosion, and then turned into a light and disappeared.

Not long after, when the other monks from Haisha Island came to check, Chu Xin'er had already taken out the magic weapon wooden boat and was moving quickly on the sea.

This time, she fought to the death with the black-robed man, and did not get any loot, but Chu Xin'er was not depressed at all, but was still a little happy.

She was playing with the wooden sword in her hand at the moment, and after trying to refine it just now, Chu Xin'er felt a trace of the vast aura of the passage of time and the vicissitudes of life, which was actually a treasure of time.

The treasure of time, related to the avenue of time, is the most fundamental and profound rule of the universe of heaven and earth, this wooden sword contains the rules of time, and it is impossible to eliminate the ghost king in the absence of no one urging it.

Her current cultivation realm is too low, although she can't successfully refine the Soul Devouring Sword of Years, it doesn't mean that she can't in the future, she inadvertently obtained such a treasure, how could Chu Xin'er not be happy.

After playing with it for a while, lest the wooden sword be discovered by a high-ranking monk passing by, Chu Xin'er put it away again, stretched out her hand, and a stone platform with five grooves was taken out by her.

This is the stone platform under the skeletal ancestor seat of Ling Tianzong, and the five top-grade spirit stones that she and Xiaowen used to activate the teleportation array at the bottom of the lake were deducted from above.

Later, Chu Xin'er also studied the stone platform carefully, but did not find it more useful, and gradually ignored it as time went by.

Now that I think about it, it will definitely not be an ordinary product to be cherished and carried by a master of the same level as the owner of the wooden sword.

Chu Xin'er tried to use her divine sense to probe into the stone platform to check, but she couldn't sweep it in at all, she thought that her divine sense was too weak at first, but now it is still like this, which makes her even more convinced that this stone platform is a treasure.

Stretching out his hand to flip it, five high-grade spirit stones of different colors appeared in his palm, and Chu Xin'er put the spirit stones into the groove on the stone platform according to the direction of the five elements.

There was no change on the stone platform, Chu Xin'er frowned slightly, and she tried to sit cross-legged on the stone platform to cultivate.

A trace of pure spiritual power overflowed from the stone platform, and it was quickly refined by her body, which was much easier than directly absorbing the spiritual power in the spirit stone.

And with the passage of time, the spiritual power in several high-grade spirit stones gradually thinned.

Could it be that this is the function of the stone platform? Is it just to purify and refine the spiritual power in the spirit stone and use it to assist the cultivator's cultivation? It's as simple as that?

Chu Xin'er stopped and spit out with a little disappointment, she still thought that the stone platform was really some kind of great treasure? If it was really just a few spirit stones to assist in cultivation, not to mention chicken ribs, it would not be a treasure at all.

Now is not suitable for a long retreat, Chu Xin'er plans to put away the stone platform, and then use it to cultivate and break through when she finds Xiaowen in the future.

She got up and stepped down from the stone platform, reaching out to pull a few spirit stones out of the groove.

At this moment, the magic weapon wooden boat was swayed by the wind and waves, and due to the suddenness of the incident, one of the spirit stones held in Chu Xin'er's hand did not grasp it firmly and fell in the middle of the stone platform.

Hum, the hard stone platform actually rippled like the surface of the water, and the high-grade earth spirit stone sank directly into it and disappeared, and then the ripples disappeared, and the stone platform became its original appearance again.

"This~"

Chu Xin'er's beautiful eyes widened, and she rubbed her eyes in disbelief.

Carefully staring at the restored stone platform, and counting the four spirit stones in her hand, she was sure that she was not wrong just now, that the earth spirit stone was indeed swallowed by the stone platform.

What the hell is going on? This stone platform actually ate a spirit stone, is it alive?

Thinking of this, Chu Xin'er, who was still sitting on it and cultivating just now, couldn't help but feel a little chill in her back, fortunately, the stone platform only eats spirit stones, otherwise wouldn't she be?

No, the stone platform was by no means a living creature, otherwise it would have stayed in that underground space in the Ling Tian Canyon all the time, and there were countless spirit stones there, if it could move, it would have devoured it a long time ago.

While thinking about it, Chu Xin'er put away the four high-grade spirit stones, stretched out her hand and flipped them over, and several medium-grade spirit stones appeared in her palm.

Airplanes~~

When Chu Xin'er put a few spirit stones in the middle of the stone platform, ripples like water waves reappeared, and several medium-grade spirit stones fell into it and disappeared.

And the divine consciousness she deliberately attached to the spirit stone immediately lost contact, and that trace of divine consciousness was cut off.

Next, she tried again, unexpectedly, as long as the spirit stone entered the stone platform, the divine thoughts she attached to would disappear, and as for other items, they would be directly excluded.

When Chu Xin'er took advantage of the ripples and tried to probe a finger in, what she touched was not a ripple at all, but a hard stone.

Chu Xin'er secretly scolded Shitai for being a pit goods, only eating and not pulling, only entering and not leaving, but in addition to throwing in the spirit stone, she really couldn't find any other way to explore the secret of Shitai.

Therefore, Chu Xin'er threw the medium-grade spirit stones into the stone platform one by one, she planned to see how much this guy could swallow?

Time passed slowly, and Chu Xin'er couldn't remember how many medium-grade spirit stones she had lost.

Suddenly, the stone platform finally changed, a groove suddenly lit up, and then a fiery red high-grade spirit stone appeared in it, although it was the other four grooves, a high-grade spirit stone also appeared.

"Hey, it's really a high-grade spirit stone. ”

Chu Xin'er took down the fiery red spirit stone and took it in her hand to look at it carefully, that's right, this is a high-grade spirit stone with extremely pure fire spirit power.

How could there suddenly be five more high-grade fire spirit stones in the groove of the stone platform? Could it be related to the medium-grade fire spirit stones that had just been thrown in?

Thinking of this, Chu Xin'er could no longer suppress the excitement in her heart, and immediately took out a large amount of medium-grade water spirit stones from the storage bag and threw them into the stone platform.

Hum, a moment later, in the five grooves on the stone platform, a water-blue top-grade spirit stone appeared.

"It can really upgrade the quality of the spirit stone, this stone platform is really a treasure, but the proportion is a bit pitted. ”

After confirming the conjecture, Chu Xin'er was both overjoyed and a little speechless, happy that with this stone platform, she could easily upgrade low-grade spirit stones into high-grade spirit stones.

But the problem is that about 500 medium-grade spirit stones are thrown in to give a high-grade spirit stone, which is even more deceptive than the proportion of some black market exchanges outside, so the gains and losses outweigh the losses.

Wait, the medium-grade spirit stone can be upgraded to the high-grade spirit stone, so can the high-grade spirit stone be upgraded to the top-grade spirit stone?

The best spirit stone is a legendary thing in today's immortal cultivation world, and any piece of it can be sold at auction for a sky-high price, which is not applicable to the exchange ratio of spirit stones under ordinary circumstances.

If this stone platform can really upgrade the top-grade spirit stone into the best spirit stone, even if it is an exchange ratio of five thousand to one, Chu Xin'er can make a lot of money, the key is that she will need to use the top-grade spirit stone when she returns to Pingzhou in the future, how can she not care.
