The Mystic Core is a silvery-white crystal, a bit like a magic crystal, but the internal structure is extremely sophisticated, like a treasure containing a small world.

The mysterious core is close to the energy body, so it can be directly turned into an energy mark and worn closely, which means that it does not need to occupy the equipment position.

Zhang Kai put the mysterious core on his chest, and as soon as he felt the warmth of his chest, the mysterious core was integrated into his body, which increased his spiritual value, spell strength and other attributes a lot.

The Mystic Core requires pure energy, which seems to be available to all kinds of energy crystals.

100 units of pure energy, almost the energy contained in 10 magic energy crystals, Zhang Kai still has a lot of magic energy crystals in his hands, and he directly upgraded the mysterious core to the black iron level.

Looking at the energy required to level up, it has changed from 100 units to 500 units, and you need to absorb 1 energy crystal with special attributes.

After getting the mysterious core, Zhang Kai also knew that the energy crystals with special attributes absorbed this time would affect the attributes of the mysterious core in the future, and he might have to absorb the energy crystals of the same attributes when he upgraded in the future.

"This mysterious core of yours is a super core born together with my Hex evolution core, but this mysterious core has never been controlled by the mechanical pioneer, and I didn't expect it to become your thing in the end."

"If you want to upgrade the mysterious core, it's best to use thunder energy or fire energy, whether it's used for combat or production, both of these energy are the best choice."

The type of special energy absorbed by the mysterious core is related to its future form, and as the energy core, the energy of the lightning system and the fire system can be both combat and production, so these two systems are naturally the main ones.

"Prosperous, remember to help me collect the crystals of the fire system, I will be of great use in the future!"

Energy crystals are a special kind of material, which can be used as consumables, and some powerful spells need this kind of casting material, or use it to provide energy, which has applications in engineering.

Zhang Kai has a fire crystal in his hand, which was dropped when he killed the fire demon in the Dryad Secret Realm before, and he used it to upgrade the mysterious core to the bronze level, and to upgrade it to the silver level, the energy crystals required are even more.

Mystic Core: Bronze Gear. Spirit +25, Mana +400, Ability Power +120. Incidental Skills: Energy Charge, Energy Shield, Energy Storm.

Energy Charge: Passive Effect: Recovers 2 mana per second, instantly recovers 250 mana after active use, and has a buffer time of 60 seconds.

Energy Shield: Passive: Increases magic resistance by 50 and reduces magic damage by 10%. When activated, an energy shield is formed, providing 10 shield points for each mana consumed, with a base cost of 100 mana, a base shield value of (0.5 * max health) points, and an increase of 50% of the energy shield's effect on negating spell damage. Cooldown is 30 seconds.

Energy Storm: Level 1. Unleashes a devastating energy storm that deals (1000+1.5*Spell Power) spell damage, increases Energy Storm's damage by 20% per second, and consumes 100 mana per second. (This skill can be upgraded with experience points, and the experience points required to upgrade to level 2 are 1 million).

Growth: Can be upgraded after absorbing 2000 units of pure energy and 5 energy crystals (limited to fire attributes), currently absorbing energy: 0/2000, absorbing energy crystals: 0/5.

After the upgrade, the mysterious core attribute has increased a lot, and Zhang Kai's magic value has exceeded 1,000 points at once, which can probably support the energy storm for more than ten seconds.

"When your mysterious core is upgraded to gold level or above, you can cooperate with me to study psionic technology, and this mysterious core contains powerful energy."

Dadong was studying his heroic legacy, and Zhang Kai saw him walking towards an Iron Guard.

Contrary to Zhang Kai's expectations, Dadong raised the metal staff in his hand and pointed at the Iron Guard, and an electromagnetic pulse shot out from the metal staff in his hand, and the Iron Guard immediately froze.

Electromagnetic Disruption Effect!

The electromagnetic disturbance made by Dadong is obviously much more effective than the electromagnetic bomb, and the Iron Guard is simply completely paralyzed, and Dadong has no reaction when he walks in front of it.

With a flick of the mechanical arm, Dadong quickly opened the Iron Guard's chest, and a magic energy crystal glittered inside.

Zhang Kai thought that Dadong would directly dismantle the Iron Guard, but he didn't expect him to use a metal rod to stab the Iron Guard's energy core, and countless data were imported, and the Iron Guard regained its mobility.

In the shocked eyes of everyone, the Iron Guard walked behind Dadong, like the most loyal guard, guarding him at all times!

Now Dadong is not only doing to solve the Iron Guard, but to directly control it!

"I'll go! That's what mechanical pioneers are capable of? You can actually control the Iron Guard! Then we can also form an army of steel and beat those monsters to death! ”

Dadong shook his head: "It's not that simple, I've just obtained the Hero Inheritance now, and the mechanical creatures I can control are limited, so I can only take the elite route." ”

"Unless I use the War Cube to control the entire control core of the Steel Fortress, then I can control most of the mechanical creatures in the Steel Fortress."

Seeing Zhang Kai's curious gaze, Dadong took out a simple Rubik's Cube with six sides, this metal Rubik's Cube looked like a toy, but it was an important treasure of the mechanical pioneer.

War Cube (Tier 0): A special treasure that can be used as a control hub for a city to build a war fortress.

War Legion: Controls 2000 mechanical creatures.

War Mill: Controls 5 production workshops and can produce mechanical creatures.

War weapons: It can control 10 production lines and can make war tools.

Growable: Growth requires the absorption of a large amount of energy and special substances.

The War Cube is a special treasure dedicated to city building, and it can control a mechanical legion to defend the city, just like a smart computer.

Like the Iron Fortress, a fortress controlled by mechanical creatures, this War Cube is simply tailor-made for this, as long as Dadong and Zhang Kai can enter the control core, they can almost control the Steel Fortress!

"Haha, with the War Cube, it will be much easier for us to take down the Steel Fortress!" Zhang Kai was happy in his heart, this matter really took a turn for the better.

Dadong raised the metal staff in his hand: "Actually, this is the most powerful place for the Mechanical Pioneer Hero Inheritance." ”

Zhang Kai asked suspiciously: "This is?" ”

Dadong said with an obsessive face: "This is the Hex Evolution Core, and it is also an upgradable piece of equipment, and the beauty of it will start with the mechanical pioneer." ”

"Unlike the backstory of League of Legends, I learned from the heroic legacy of the mechanical pioneers that the mechanical pioneers are the inheritors of Hextech, a great heritage that combines magic and technology."

"With Hextech, mechanical pioneers can craft all sorts of technological products, such as psionic guns, psionic powerplants, and more."

In fact, Hextech can be regarded as a powerful branch derived from engineering, and it can be regarded as a civilized power system!

"And in the core of Hex's evolution, there are all the scientific and technological achievements of Hextech."

"The mechanical pioneers also added intelligent systems to the evolutionary core, so that they can assist in research, and the effect is like a highly intelligent computer host, I believe you also understand the importance of computers to modern technology."

"It is only by obtaining this evolutionary core that the mechanical pioneer can achieve such a high achievement, and the Hex's evolutionary core has become the most important existence in the inheritance of the mechanical pioneer."

"I was supposed to be able to obtain this evolution core when I had risen many levels and gained more inheritance power, but after Zhang Kai, your counterattack destiny came into play, I obtained this crucial item earlier."

Seeing Zhang Kai's confused face, he obviously didn't understand the power of Hex's evolutionary core, Dadong didn't talk nonsense, and directly took out an electromagnetic bomb.

Dadong lifted the Hex Evolution Core and stabbed directly at the electromagnetic bomb, but this extremely easy bomb did not explode immediately, but quickly disintegrated under the power of the Evolution Core!
