The dragon vein kobold took the lead and rushed to the front, a narrow passage for the nine-clawed white bone demon spider, but extremely spacious for it.

It easily rushed straight into it and ran at full speed.

"It's like it's getting stronger again. The ancient goblin couldn't help frowning as he looked at the back of the dragon vein kobold, and its speed seemed to have become faster again.

Chen Yiming checked the Book of Summoning, and the level of the dragon vein kobold had been successfully re-upgraded to level 6. Hundreds of rare-level monsters provide it with tens of millions of experience points.

After the previous soul refining was over, the level of the dragon vein kobold was all reduced to zero, and the level of 1:1 was all converted into the layers of the soul refining.

After clearing zero, the experience required to upgrade is not to continue the previous level, but is the same as the experience required for the first upgrade, which only requires 100 experience to upgrade from level 1 to level 2, and only 1000 experience to upgrade from level 2 to level 3......

With the addition of the twelfth level of the Soul Refining, the Dragonvein Kobold is now equivalent to having an additional bonus of 18 levels.

Chen Yiming estimated in his heart that the dragon vein kobold was about 5.5 times that of level 0.

This is nearly double the previous triple.

The speed at which this soul refining increases combat effectiveness is really terrifying...... It's just a pity that improving the soul refining also requires a lot of soul power, which is troublesome, if only there was a stable channel to obtain soul crystals.

Chen Yiming communicated his thoughts with his younger brother, and the younger brother said, "Brother, I think that the training tower we went to last time may also reward soul crystals. ”

"It probably would. Chen Yiming nodded.

"When I go back, I'll add another bounty soul crystal, a rare one-star living monster, and trade for a soul crystal. Chen said in surprise.

"Then you're a profiteer. Chen Yiming laughed.

The value of a soul crystal is far greater than that of a rare one-star monster, and even a rare three-star monster may not be worth as much as a soul crystal.

But the value of something is never due to its own value, but to the value of other people's needs.

Just as the value of a bottle of water in a bustling urban area is completely different from the value in a desert that is inaccessible, although the bottle of water itself has not changed in any way, he will even be willing to buy the bottle of water from a merchant at a hundred, a thousand times the price of someone who needs it in the desert.

The same is true for these people now, although the soul crystal is a strategically important material that tends to be biased towards development.

But for those who can't even reach the door of soul training, it's just a stone of no use. Or even if they really know, there are people who are willing to exchange.

After all, as long as a summoned beast of rare quality is in control now, it can definitely dominate one side in the city and create a small force.

"You can set the price yourself. Chen Yiming said.

A white light flew through the wall, and when he opened the Book of Summoning, Chen Yiming saw the spirit of the nine-clawed white bone demon spider.

The battle is over, but that's to be expected.

This nine-clawed white bone demon spider itself was seriously injured, and then the dragon vein kobold, whose level was raised to level 6 when he hunted the spider just now, was able to crush this demon spider in terms of combat power, not to mention that it was in a seriously injured state.

"Master, I found this!"

The dragon vein kobold came out of the cave and said excitedly.

"What?" Chen Yiming followed.

The dragon vein kobold came out of the cave he had just burrowed into, holding a black hedron in his hand.

Chen Yiming took the spar in his hand, and the Book of Summoning reacted.

【Item】Black Crystal (a natural crystal formed by condensing the essence of the earth, rich in magical power, can promote evolution when taken for a long time, and can also be used to heal injuries) (only for monsters below the monarch quality)

Chen Yiming's eyes froze.

Chen Jing was also very surprised.

"Can it allow summoned beasts to evolve directly?!" Chen said in surprise.

"Quite possibly. Chen Yiming nodded, "This nine-clawed white bone demon spider should have evolved into a masterpiece after taking this black crystal for a long time." ”

As for why the nine-clawed white bone demon spider went here, Chen Yiming also guessed that the black crystal could heal injuries, and after being injured, it instinctively ran to the location where the black crystal was.

Chen Yiming took the black crystal in the hand of the dragon vein kobold, "You go and lead the way." ”

When I was fighting the Nine-Clawed White Bone Demon Spider just now, all the remaining hunting spiders had run out.

I couldn't beat it again, so I naturally escaped.

There are many crevasses and caverns in this underground cavern, and there are many directions for hunting spiders to escape.

However, Chen Yiming doesn't care now, he can't run the monk to the temple.

It's all in underground caverns, but black quartz is a surprise.

Chen Yiming always thought that only his own synthesis ability could make the summoned beast evolve.

Now it seems that this is not the only case, there are other ways in nature to evolve monsters or summoned beasts.

"This is where the host was found. The dragon vein kobold led Chen Yiming and them through this tunnel several hundred meters long.

Passing through the tunnel is a cave that shows signs of being mined.

The walls are full of spider claws.

The nine-clawed white bone demon spider didn't appear for the first time before, and it should have been hiding here to mine black crystals and then take them, which is also the reason why its quality is so high.

Chen Yiming was heartbroken, the nine-clawed white bone demon spider didn't know how much it had mined, it was a waste!

The flashlight shines on the surrounding rock walls, and the black crystals reflect a faint white light.

Chen Yiming didn't know how much of the remaining reserves, and he initially considered using people to mine them, but then he himself vetoed the idea.

Because...... Chen Yiming threw the black crystal to the green skin and let it eat it.

Greenskin swallowed it in one gulp, and then Greenskin's evolution progress slowly increased by a little bit every ten seconds, lasting for nearly ten minutes or so before stopping.

And then there are the kobolds, but these kobolds are coerced and subdued by the dragon vein kobolds, although they seem to be obeying the orders of the dragon vein kobolds at the moment, but if they really face the danger that threatens their lives or the temptation of black crystals that can improve the quality, it is difficult to guarantee that they will not be able to do some behavior.

This black crystal can be swallowed as long as it is swallowed, unlike gold mines.

The previous nine-clawed white bone demon spider dominated this area and did not allow other hunting spiders to approach.

Otherwise, it wouldn't be a gem, and I haven't even seen a rare two-star star.

Which summoned beast should I give it to... Chen Yiming fell into deep thought.

Summoning beasts above the gem are not considered for the time being, it will take too much time.

Those with a large number of low-level form "materials" are not considered for the time being, and there are summoned beasts that can evolve.

Blaster Demon Firefeather Bird?

Chen Yiming's heart moved.

I don't know when the Evil Tree wants to scale, but the Blaster Demon's telekinesis ability is still quite useful, but as the quality of the summoned beast increases, the Blaster Demon gradually can't keep up with the rhythm.

And the ability of the Blaster Demon is also very suitable for mining, which is the best ability.
