Because condensation is only a ring of runes, the strength of its influence on the high-level energy of magic energy is very weak.

This rune can only attract magic energy within a maximum of one meter.

It's hard to get deep.

It was only a matter of minutes for him to engrave a few more runes.

According to Lawrence, it takes at least ten minutes or even half an hour for the average first-order rune carver to successfully carve a rune.

The ranks of the Ill Masters are based on skill levels.

Rune carving level 1~10 is the first order.

11~20 is the second order.

And so on.

The same is true for other life occupations.

This is the grading method used uniformly in ancient shelters.

Cheng Shen's rune carving proficiency was fast enough, and he worked tirelessly to create hundreds of pieces of sophisticated equipment last night.

The rune carving skill has been upgraded to level 5, but it is still not out of the category of a first-order rune carver.

However, his efficiency in carving runes is unattainable by any rune carver.

Not to mention speed.

Ordinary rune carvers simply can't control energy precisely.

Their success rate in portraying a rune is only about 10 percent.

That's right, it's not even a one-fifth success rate, which is the limit of what a normal first-order runic carver can do!

No wonder the missionaries misunderstood him for losing money and making money.

Such an astonishing gap, if it weren't for him personally, I'm afraid Cheng Shen himself would have been a little suspicious......

Soon.

The stone pillars of the outer caves were all carved with condensation runes by him.

The demonic energy floating in the cave decreased at a speed visible to the naked eye, and it was all concentrated at the top of hundreds of stone pillars, and such a huge amount of demonic energy was all gathered in one place, and the condensation speed of liquid demonic energy was at least ten times higher than before.

Tick......

Tick......

It suddenly seemed to rain in the whole cave.

[The task has been completed, and all the permissions to open the copy of the Polluted Library have been unlocked!] You can check it out in detail after exiting the dungeon! 】

……

That's it.

His previous guess was indeed correct, the purpose of the system was to find a way to use magic energy leakage to convert energy crystals.

Perhaps, this is not the only solution.

But it's the best fit for him.

Cheng Shen was in no hurry to quit.

His purpose was not just to address the leak in the outer cave.

If you can intercept all the several magical energy veins connected to the blue dragon, the output of energy crystallization can be increased several times!

"Are these veins formed naturally or are they influenced by other forces......

Cheng Shen returned to the cave and carefully observed the direction of the vein.

He tried to crack the rocks to find the root of the veins.

However, the rocks here were so hard that he could only smash them with all his might.

Without the terrifying power of the blue dragon, it was undoubtedly quite a huge task for him to find the source of the vein.

Cheng Shen quickly gave up.

Since this is the case, he can only use the least efficient method to depict the condensation runes on the veins, and then use the energy link technology to connect the runes with the external runes, and transmit the magic energy in the opposite direction.

The process is slow.

With Cheng Shen's ability, it took nearly an hour to get it.

Airplanes!

The runes engraved on the veins were all in motion at this time, blooming with deep blue light, and the crystalline blue bands of light were densely spread throughout the cave like wires, sending magical energy outward.

"The existing energy link technology is still poor, and a short distance of more than ten meters will produce 30% of the energy loss."

Cheng Shen shook his head.

But.

He immediately thought of the magic energy core he had collected on the magic energy puppet, which must contain higher-end energy link technology, and when he finished researching, he would be able to upgrade the energy channel here.

Countless crystal blue veins were all linked to several stone pillars close to the inner cave, and at this time, the light condensed at the top of these stone pillars was already as bright as a small sun, and even condensed into pieces of crystalline layers.

Crash......

The liquid of magic flowed down like a stream.

The magic energy conveyed by the entire ten magic energy veins was all gathered on these stone pillars, even if 30% was lost in the process, it was also a rather large amount of energy, and it was not surprising that there would be such an amazing effect.

In the end, Cheng Shen picked up the more than 100 primary energy crystals that had been produced in the cave and withdrew from the dungeon.

[Gain: XP +30600!] 】

[Get: Gold +150!] 】

[Obtain: Dungeon Chest (Rare)!] 】

[Obtained: Boss Chest (Perfect)!] 】

……

The moment you exit the dungeon, all the main quests are settled.

Cheng Shen's experience slot, which had just been promoted to the next level, suddenly jumped up one level, and he was also very fast from the next level.

He then looked at the unlocked quest permissions.

【Polluted Library】

"One Sword Alone"

[Unlock Resources: Energy Crystallization Mine: 2% development, can produce 200 primary energy crystals every 24 hours]

……

"I see, the monsters in the dungeon will only be refreshed if they consume additional magic energy."

Cheng Shen saw the detailed introduction before he knew it.

Let's put it this way.

His previous fears were all true.

But then again, Cheng Shen looked at the end, he had only developed 2% of that energy crystallization mine?!

He had clearly made use of all the resources he could use......

Is it necessary to send people to station and thoroughly mine the entire vein?

Just 2% has 200 energy crystals every 24 hours, how amazing would it be if all of them could be developed?!

Cheng Shen's heart was beating wildly.

Immediately, he connected to the scout guards, and brought back Dajian, who was exploring the veins, and the farmers he led.

in the process.

Cheng Shen opened all the two treasure chests rewarded by the dungeon.

[Obtained: The Sleeve of the Arcane Surge!] 】

[Obtained: Cold Jade Crystal!] 】

……

Both chests can only be found with items from the dungeon, and this is also a reward for the first time.

No matter how many times you brush it in the future, quests will not appear.

The sleeves were one of the secret surges, and Cheng Shen first equipped the rat mage.

Cold jade crystals are an important material for creating the Eternal Frost Set.

Cheng Shen took out the staff drawing, this drawing can only be learned by carving runes at level 10, and it can't be used for the time being.

But he can see the need for materials.

Just to create this staff, you have to use two cold jade crystals, and the other parts also have to consume one.

Jade Crystals can only be dropped by Owik.

A total of eight pieces are required.

In the absence of additional rewards for dungeons, I don't know how many times I have to swipe.

However, this set of equipment is a set with the highest level of seven-piece attributes, which is one level higher than the rarity of the sacred set.

I think the attributes will not be bad.
