After selecting the spell, Zhao Lun left the underground base and has been practicing the 'meteorite technique' on the ground.

After five or six hours of hard work, Zhao Lun was finally able to perform the 'meteorite technique', although it took a full minute from chanting to casting, but it was also a huge breakthrough for Zhao Lun.

After getting this huge breakthrough, Zhao Lun originally planned to make persistent efforts to become proficient in the 'meteorite technique', but was stopped by Best, who ran up from the underground base.

"My lord, the construction of the mutated version of the magic tower has been completed, and you need to activate it yourself!"

"Is it finally done?"

Zhao Lun's eyes flashed, and he immediately stopped the cultivation of the 'Meteorite Technique', and followed Best to rush down the underground base, and after a while, they came to the mutated version of the magic tower.

When he saw this mutated version of the magic tower, Zhao Lun was almost stunned. Sure enough, it's a mutated version, and it's much more conspicuous than the normal version of the magic tower.

This magic tower is about thirteen meters high, the architectural style is biased towards the Western Gothic style, the whole body is snow-white, there is no sense of hierarchy at all from the appearance, and the most special thing is that there are three skulls suspended at the peak of this magic tower.

Zhao Lun looked at it for a moment, then withdrew his gaze, and opened his arms to chant a spell.

With Zhao Lun's current strength, chanting the construction spell is no longer difficult, and Zhao Lun has completed it in less than a minute.

'Ding'

At the same time, in Zhao Lun's soul fire, the prompt sound of the system also jumped out, and Zhao Lun subconsciously turned on the system to call up the information of the mutated version of the magic tower.

Tier 1 Magic Tower* mutation

Category: Support/Attack

Description: This is a building with excellent potential.

Upgradable

Cumulative progress of upgrade profile: 00

"Isn't this attribute still the same as before? Hey, no, no, it's a little different. "Zhao Lun's eyes flickered, and he clicked on the 'Spell Mutation', and soon the system that had not moved before quickly jumped out of a piece of information.

Special Attribute: Spell Mutation

NOTE: Consumes a small amount of energy to mutate the target spell.

"A small amount?" Zhao Lun sneered at this ambiguous word, quickly called up the information transmitted by the mutated version of the magic tower, and looked at the 'price list' Zhao Lun gasped.

"What the fuck is this called a small amount?"

Level 1 Spell Mutation: Consumes 1 Stygian Crystal

Level 2 Spell Mutation: Consumes 5 Stygian Crystals

Level 3 Spell Mutation: Consumes 25 Stygian Crystals

Fortunately, Zhao Lun has no heart now, otherwise Zhao Lun might not have spurted out a mouthful of old blood.

After brewing for a while, Zhao Lun calmed down.

"Forget it, anyway, I can harvest 35 Stygian Crystals a day now, two third-level spells, and five second-level spells are only 75 in total, but the Stygian Crystals are amazing, and I can collect them all in three days." ”

Zhao Lun said as he clicked on the 'Spell Analysis' next to the 'Mutation Spell'.

Special Attribute: Meditation Analysis

Description: Consume a small amount of energy to interpret meditation.

"Another small amount?" Zhao Lun snorted coldly, and once again called up the information transmitted from the mutated version of the magic tower, this time Zhao Lun was not immediately hit, because the mutated version of the magic tower did not clearly indicate how much energy fire was needed to analyze the 'meditation technique'.

Zhao Lun thought about it, went directly to the side of the mutant version of the magic tower, and entered the 'meditation technique' obtained from the level 8 skeleton mage into the magic tower, and then clicked on the 'meditation technique' to analyze.

Resolution Target: Unnamed (Meditation)

Grade: Normal

Cost: 10 Stygian Crystals

Does it parse?

Yes/No

"10 Immortal Crystals? It doesn't seem to be too expensive, it's a solution!" Zhao Lun waved his hand without hesitation after discovering that the price of the Analytic Meditation Technique was far lower than he expected.

"Ding, there is not enough energy to parse!"

"Huh?" Zhao Lun was stupid, and it took him a long time to remember that all the 'energy fires' he had been storing in the 'Bone Transformation Pool' these days, and he hurriedly ordered to Best on the side: "Send a hundred level 5 skeletons immediately, let them go, bring me all the 'energy fires' on the bone transformation pool." ”

After watching Best go about execution, Zhao Lun came to the side of the mutated version of the magic tower and began to test the indicators of the magic tower. After Zhao Lun's hard work for more than half an hour, he finally came up with the indicators of the mutated version of the magic tower.

Compared with the normal version of the magic tower, the main differences between the mutated version of the magic tower are the three aspects of 'Spell Mutation', 'Meditation Analysis' and 'Spell Attack'.

'Spell Mutation' and 'Meditation Analysis' don't need to be talked about.,These two functional magic towers didn't have it in the first place.,But this 'Spell Attack',,It's necessary to talk about it.。

'Spell Attack' was originally available in the ordinary version of the magic tower, but the 'spell attack' of the ordinary version of the magic tower is the magic tower's own, and the attack power is almost the level of the second-level spell, and the attack range of the single body is about three hundred meters, and the ordinary version of the magic tower spell attack is to consume the energy provided by the lord.

The mutated version of the magic tower is different, the mutated version of the magic tower itself has a certain energy absorption and reserve function, the energy used in the 'spell attack' is the use of the energy stored in the mutated version of the magic tower, but the energy of the mutated version of the magic tower is limited, according to the information transmitted by the mutated version of the magic tower, the mutated version of the magic tower can probably store five third-level spells of energy, although it is not a lot, but it is enough to support a battle, and if necessary, the energy of the 'spell attack' Zhao Lun can also provide.

The spell attack of the mutated version of the magic tower can be set, as long as there are burned spells in the magic tower, you can choose it, for example, Zhao Lun just set the spell attack of the mutated version of the magic tower as 'meteorite technique', and it was very successful, and the power was much stronger than the nondescript spell cast by Zhao Lun himself. Moreover, the range of the mutant version of the magic tower's attack is still very wide, with a distance of five hundred meters, and the 'meteorite technique' chosen by Zhao Lun is also very appropriate.

In this way, the ultra-long distance, as well as the spells that are in sync, combine the two to make the spell attack of the mutated version of the magic tower ignore the soil layer of tens of meters and only act on the ground.

However, it is not completely without shortcomings, although the soil layer of tens of meters is considered thick, but as a third-level spell, the attack power of the 'meteorite technique' is quite terrifying, and the one that fell on the body fell with a blow fell down a large pit of more than ten meters, and the entire territory was trembling, and the underground base almost collapsed.

This incident also reminded Zhao Lun that his underground base is actually not very impregnable, and if conditions permit, it is best to strengthen this underground base.
