Putting Wang Yu's matter behind him, Li Ran sat up from the sofa with a surging mood.

"I've been stuck at VIP3 for a long time, and this time I can finally upgrade. I'm so excited!" Li Ran could hardly contain his excitement.

He quickly stepped into the training room in the villa, opened the isolation formation, and then activated the Tuanpu in his dantian.

Suddenly, a wood-green round hole opened in front of him. Li Ran stepped into it, and the world suddenly changed. He had already arrived at the center of the Wood Spirit Space Hall.

The Wood Spirit Space was refined by a powerful being who cut off a piece of space fragment, and the futon is the only key to the Wood Spirit Space.

After refining the Tuanpu, one can become the sole owner of this space, and Li Ran can activate the Tuanpu from anywhere and enter the space.

Li Ran came out from the back door and flew towards the cave. This time he did not encounter any obstacles and directly passed through the layer of formation prohibition.

After flying down for a while, Li Ran arrived at the bottom of the cave. The bottom of the cave was still dazzling and brilliant, but compared to the first time he came here, it was not only much dimmer, but also lacked some vitality.

Li Ran could also understand it. After all, the removal of the wood spirit marrow would definitely have a great impact on the environment here.

Li Ran did not stay there for too long, but walked towards the direction of the original wood spirit marrow.

The closer he got to the location of the wood spirit marrow, the higher the quality of the wood spirit stones under his feet and around him became. As he walked, all the visible areas around him were filled with medium-grade spirit stones, and there were even a few rare spirit crystals!

Spirit crystals are also divided into low-grade, medium-grade, high-grade, and top-grade, just like spirit stones. But even the lowest-grade spirit crystals are much more precious than top-grade spirit stones!

The spirit crystal not only contains extremely pure spiritual energy from heaven and earth, but also allows practitioners to use it for their own benefit without any refining.

When fighting against the enemy, the spirit crystal can even help to quickly restore the spirit energy and thus defeat the enemy!

Moreover, when the spirit crystal is used up, it can automatically absorb the spiritual energy between heaven and earth to restore itself and can be used indefinitely.

Moreover, it is extremely hard and can be used as the main material for refining equipment.

That’s not all, what’s more important is that he can lay eggs!

When the spiritual energy in the spirit crystal is fully stored, it will begin to gradually transform the surrounding ordinary stones into spirit stones!

The fact that light can produce spirit stones makes spirit crystals extremely precious. Basically, no one is willing to drain the pond to catch fish and take out spirit crystals for trading!

Generally speaking, the spirit stones that spirit crystals can transform into are of the same quality as their own.

That is to say, low-grade spirit crystals can produce low-grade spirit stones, medium-grade spirit crystals, high-grade spirit crystals, top-grade spirit crystals, etc. The spirit stones produced are all spirit stones of corresponding qualities.

Li Ran took a piece of medium-grade spirit crystal in his hand. He could easily feel how pure and rich the spiritual energy contained in it was!

Not only that, the spirit crystal in his hand is not just an ordinary spirit crystal, but also a wood-attribute spirit crystal, which is more precious than an ordinary spirit crystal.

He read in the book that in addition to generating attribute spiritual energy, attribute spirit crystals also have very special functions!

For example, the medium-grade wood spirit crystal in his hand contains spiritual energy that has healing properties!

"This is truly an unimaginable wealth!" Li Ran now wished he could immediately grab the cute little Mu Ling and lick her face with saliva.

Li Ran would definitely not use the spiritual crystal, not even if he was beaten to death. It would be best if he killed this idea, because if he did it once, he would do it again!

"100,000 Spirit Vouchers, that should be enough..."

Li Ran was a little worried. After all, the wood spirit marrow was only medium-sized, and most of the spirit stones that could be transformed were low-grade spirit stones, which could not be transformed into spirit coupons.

Only mid-grade spirit stones can do this, but there are not many mid-grade spirit stones.

But there is no point in worrying. Let’s first see how many mid-grade spirit stones there are here.

Li Ran swept away all the mid-grade spirit stones he saw along the way, and stopped only when there was no mid-grade spirit stone left at the bottom of the dragon vein.

Probably a medium-grade spirit stone!

Although many large medium-grade spirit stones have not been cut into even pieces, Li Ran has already used his spiritual sense to divide them according to the measurement units stipulated by the federation.

"It feels like it's not enough. Damn, only one. A mid-grade spirit stone is roughly equivalent to one spirit coupon. I need 100,000 spirit coupons to upgrade. It's so uncomfortable!" Li Ran was a little depressed.

"Do I really have to use Spirit Crystals? No, no, I absolutely cannot have that thought. Even if I upgrade to VIP later, I can't use Spirit Crystals. Spirit Crystals are not consumables like Spirit Stones!"

Li Ran suppressed the thought of using the spirit crystal, and then decided to take a long-term view. But just when he was about to activate the cushion and go back, he suddenly thought of something.

"exchange!"

Li Ran took out a medium-grade wood spirit stone that was closer to the federal cutting standard from the inventory and then exchanged it.

"3 spirit coupons!" Li Ran was stunned for a moment, then he was ecstatic.

Yes, yes, this mid-grade spirit stone is not an ordinary spirit stone without attributes. It is an extremely rare spirit stone with attributes. How could its price be the same as that of an ordinary spirit stone?

"I'm so stupid..." At this moment, Li Ran seemed to have turned into Xianglin Sao.

Exchange! Exchange...

Li Ran couldn't wait to exchange all of the approximately 40,000 medium-grade wood spirit stones, leaving only 20,000, but these 40,000 were enough.

At this time, behind the words "Spirit Coupon" above Li Ran's inventory was written!

Seeing this, Li Ran immediately opened the VIP interface and clicked the upgrade button.

"...VIP level has reached four, the system is updating..." This information appeared in Li Ran's mind.

"What? This system needs to be upgraded?" Li Ran was a little disappointed. He thought he would be able to see what new things and new features VIP4 has right away, but he didn't expect that it would be upgraded.

The wait was long. Although the upgrade time was very short, only a few minutes, Li Ran felt that the days were long.

Although it was being upgraded, Li Ran was still able to open the system, but other than the inventory, he could not operate other interfaces, so he had to wait patiently.

He particularly hoped that the spiritual roots bestowed by the system this time would be the five elements spiritual roots, and he was also curious about what the system said could make up for the loss of spiritual roots.

"…Upgrade completed…"

When the information that the upgrade was completed came to Li Ran's mind, Li Ran immediately opened the system and went to the VIP interface.

upgrade!

When Li Ran clicked the upgrade button, the picture was broken as before, and then the words VIP4 gradually appeared in front of him, and then gradually became clear.

He did not immediately exit the VIP interface to receive gift packages and benefits, but instead checked the VIP4 privileges!

Sometimes he couldn't help but complain that the game system planning was absolutely unqualified. Before upgrading, he couldn't even check what privileges, gift packs and benefits the VIP had.

"Fuck, this is fierce, the training speed has doubled so much!"

Li Ran was shocked when she saw the information in the privilege!

Because in the middle of the screen it said VIP4 privileges: 24-hour non-stop idle, cultivation speed x8...
