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

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

"It seems that it has become stronger again." The ancient goblin looked at the back of the Dragon Vein Kobold, and couldn't help frowning. Its speed seemed to have increased again.

Chen Yiming checked the Book of Summoning, and the level of the Dragon-Maid Kobold has been successfully upgraded to level 6. Hundreds of rare-level monsters have provided it with tens of millions of experience points.

Before the end of the soul refining, the level of the dragon vein kobolds was all reset to zero, and the level of 1:1 was transformed into the number of layers of the soul refining.

The experience value required for upgrading after resetting is not the same as the previous level, but the same as the experience value required for the first upgrade. It only needs 100 experience to upgrade from level 1 to level 2, and only 1,000 experience for level 2 to level 3. ......

With its own level plus the twelfth level of the soul refining, the dragon vein kobold is now equivalent to having an additional level of 18 bonus.

Chen Yiming estimated from the bottom of his heart that the Dragon Maiden Kobold was about 5.5 times as high as it was at level 0.

It's nearly doubled compared to the previous three times.

The speed at which this soul refinement enhances combat power is really terrifying... It's just a pity that it requires a lot of soul power to upgrade the soul refinement. This is troublesome. If there is a stable channel for obtaining soul crystals, it would be great.

Chen Yiming exchanged his thoughts with his younger brother, and the younger brother said: "Brother, I think the experience tower we visited last time may also reward soul crystals."

"It should be." Chen Yiming nodded.

"After I go back, I will add a reward soul crystal, a rare one-star living monster, trade a soul crystal." Chen Jing said.

"Then you are really a profiteer." Chen Yiming followed with a smile.

The value of a soul crystal far exceeds that of a rare one-star monster, and even a rare three-star monster is not necessarily as valuable as a soul crystal.

But the value of something has never been attributed to its own value, but the value of other people's needs.

Just as the value of a bottle of water in the bustling urban area is completely different from the value in the inaccessible desert. Although the bottle of water itself has not changed in any way, he would even be willing to use it hundreds or thousands of times for those who need it in the desert. The price goes to the merchant to buy this bottle of water.

The same is true for these people now, even though the soul crystal is an important late-stage strategic material that tends to grow.

But for people who can't even reach the door of soul training, it's just a stone of no use. Or even if someone really knows it, someone is willing to exchange it.

After all, as long as a rare quality summoned beast is in your hands, it can definitely dominate a party in the city and create a big power.

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

A white light flew through the wall and opened the book of summoning. Chen Yiming saw the spirit of the nine-clawed white bone demon spider.

The battle is over, but this is to be expected.

The nine-clawed white bone demon spider itself was severely injured, and the dragon-veined kobold who was upgraded to level 6 when hunting the spider just now can crush this demon spider in terms of combat effectiveness, let alone it is in a seriously injured state. Up.

"Master, I found this!"

Longmai Kobold said excitedly when he came out of the cave.

"What?" Chen Yiming followed.

The dragon vein kobold came out of the cave where he had just entered, holding a black spar in his hand.

Chen Yiming took the spar in his hand, and the book of summoning reacted.

[Items] Hematite (condensed natural crystals formed by the essence of the earth, rich in magical power, long-term use can promote evolution, and can also be used to heal injuries) (only contains effects on monsters below the monarch quality)

Chen Yiming's eyes narrowed.

Chen Jing was also very surprised.

"Can it allow the summoned beast to evolve directly?!" Chen Jing said in surprise.

"It's very likely." Chen Yiming nodded, "This nine-clawed white bone demon spider should have evolved into a superb product after taking this black spar for a long time."

As for why the Nine-Clawed Bone Demon Spider went here, Chen Yiming had also guessed that the black spar can heal the injury, and after being injured, it instinctively ran to the position of the black spar.

Chen Yiming took the black spar in the hand of the Dragon Maid Kobold, "Go lead the way."

When fighting the nine-clawed bone demon spider just now, the remaining hunting spiders had all run away.

Can't beat and beat, naturally escaped.

There are many cracks and caves in this underground cave, and hunting spiders can escape in many directions.

But Chen Yiming doesn't care anymore. If he can run, the monk can't run the temple.

They are all in underground caves, but the black spar is a surprise.

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

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

"The master found it here." The Longmai kobold led Chen Yiming and the others through this hundreds-meter-long tunnel.

Going through the tunnel is a cave, this cave has traces of being mined.

The walls are full of spider claws.

Before the Nine-Clawed Bone Demon Spider didn't appear for the first time, it should have been hiding here, mining the black spar and then taking it, which is why it is so high in quality.

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 shone on the surrounding rock wall, and the black spar reflected a faint white light.

Chen Yiming didn't know how much the remaining storage capacity was. He had just considered using people to mine, but then he himself rejected the idea.

Because... Chen Yiming threw the black spar to Green Skin to let it eat.

Green Leather swallowed it in one bite, and then the evolution progress of Green Leather slowly increased by a little every ten seconds, and it lasted for about ten minutes before stopping.

Then there are the kobolds, but these kobolds were threatened and persuaded by the dragon-mai kobolds. Although they seem to obey the dragon-mai kobold's orders at present, if they really face the danger that threatens their lives or face the danger that can improve their quality When black spar is tempted, it is difficult to guarantee that it will do some behavior.

This black spar can be consumed as long as it is swallowed, unlike a gold mine.

The nine-clawed white bone demon spider dominated this area before, so other hunting spiders were not allowed to approach it.

Otherwise, it won't be a masterpiece, besides, I haven't seen even the rare two stars.

Which summoned beast should I give it... Chen Yiming was lost in thought.

The summoned beasts above the exquisite product are temporarily ignored, and it takes too much time.

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

Blaster devil? Flamingo?

Chen Yiming had a thought in his heart.

The evil tree wants to grow to a large scale, but I don’t know when, but the explosive demon’s thought ability is quite useful, but as the quality of the summoned beast increases, the explosive demon gradually fails to keep up with the rhythm.

And the blasting demon's ability is also very suitable for mining, this is the most outstanding ability.
