After solving the three split consciousnesses that can be freely controlled, Alan set his sights on the mitochondrial harvest of the virus this time.

After a short period of decomposition and refinement, Alan was pleasantly surprised to find that with the previous accumulation, he had obtained three thousand units of prototype virus mitochondria.

Three thousand units is a very tempting number, which means that Eren can increase his abilities by three or increase his speed to the second tier!

In the list of abilities, each ability is divided into three levels, the cost of the first order is one thousand, and then it will be doubled, the second level is two thousand, and when it reaches the third level, this number will jump directly to ten thousand! In other words, to raise an ability to the full level, it would require 13,000 units of prototype virus mitochondria. That's definitely a scary number!

Opening the list of abilities in his mind, Eren began to have a hard time. He wanted to take the blade or the hammer up a notch, but he hesitated again, and finally his eyes fell on the speed option. The second-order speed advancement once again increases Allen's speed when running, by about 30 percent, and also provides an extremely useful ability - sprint! In the run, Alan can concentrate the prototype virus on his legs to achieve a short-distance sprint, under the sprint effect, Allen's body is in a virion state, completely immune to any attack, just like the flashing ability of the black revolver. It's just that the flicker is farther away, which is great for escaping combat, while the dash is the opposite, which is better for avoiding damage and chasing down enemies in combat.

Alan hesitated for a moment, gritted his teeth, and put two thousand units of virus mitochondria into the second-order speed option. Looking at the remaining thousand units of virus mitochondria in his hand, Alan finally turned over the options of virus ability. Since the next thing to face is the evolved Kelly, Allen must work the attack power. Defensively, relying on his second-order speed and sprinting ability, Allen is confident that he will not fall behind, so the next thing to consider is how to knock the opponent down.

In terms of the virus ability of the attack, the claw blade and the war hammer are side by side, and the attack power of the lightning ball sprayed by the black revolver is not high, it is more for flickering, so Alan directly ignored it. Then all that remains is to choose between the claw blade and the warhammer.

The first level of the Claw Blade is called - Flowing Shadow! The black claw blade is upgraded to a disembodied shadow blade, and grants the user the ability to hide in the shadows. After upgrading this ability, Eren's claw blade evolved into the Shadow Blade, and allowed Eren's body to merge with the shadows without being noticed. Judging from the description of this ability, the advanced direction of the Flowing Shadow is similar to the assassination system, and it is more about avoiding head-on contact and thus assassinating!

The first advance of the Warhammer is called - Boiling! The pitch-black hammer is upgraded to a boiling hammer that burns black flames. After mastering this ability, the attack will have a strong Black Flame with both corrosion and burning effects, and also give the user a short-term power amplification effect. The boiling advancement direction is close to the berserk warrior, and it is definitely the preferred way to advance by killing the enemy head-on!

Looking at the two different paths of advancement, Alan began to make difficulties, he liked both very much, the flow shadow can make Alan advance and retreat freely, kill people invisibly, and although he can't face the battle head-on, he can solve the opponent in secret. And the boiling gives Eren the power to face the enemy head-on, thinking about the scene of wielding a war hammer to kill makes Alan's blood boil, no wonder this war hammer is called the boiling hammer.

But blood is blood, and Alan didn't plan to really fight Kelly head-on. Raymond's current biofusion technology is definitely above Sabnis, so Kelly's transformation must be thorough, crazy, and even terrifying. Combining blades, warhammers, and stealth with an extreme focus on attack, Kelly would be an out-and-out killing machine. So in a head-on battle, Allen's chances of winning were very few, and after thinking of these, Allen put the last thousand units of virus mitochondria into the advancement of the Shadow Blade.

Alan slowly opened his eyes in the nutrient solution, he looked down at his hands, the pitch-black lines began to beat, and his left hand was still in the shape of a black claw blade, but the claw blade became more slender and thin, like five black slender leaves, it was difficult to attract the attention of outsiders.

The change in his right hand is much more obvious, what makes Eren most curious is that the claw blade of his right hand has disappeared, but Alan holds a narrow short sword in his hand, this short sword is only sixty centimeters, the pitch-black blade is almost transparent, and the black qi that swirls can easily pass through the blade. The position of the sword knob protruded into countless black lines, which in turn connected with Alan's wrist. Feeling the sharpness on the black blade, Alan only felt that his body was also wrapped in a black mist!

The training pod suddenly sounded an alarm, and the hatch was slammed open by an external force, and Sabnis and Fasqi looked inside at the same time.

"Why do signs of life go to zero?" Sabnis said out loud in confusion, and even Fasqi looked worried, but the two of them poked their heads in and saw a black figure lying quietly in the emerald green nutrient solution. Fasqi couldn't help but sweep a mental fluctuation curiously, and she looked at Alan in surprise: "How is it possible, your body actually blocks my spiritual perception?" ”

Alan sat up with a smile, he was completely wrapped in a black mist at the moment, like a black shadow: "Of course, otherwise why did I finally choose to advance in this direction." With this ability, I can at least take a little advantage when facing Kelly, since it is a battle of life and death, of course, the sooner I can solve the opponent, the better. Sabnis, help me prepare some special self-detonating bugs, I'm going to make Kelly lose at least half of his combat power before he even sees me. ”

Alan said that he couldn't help but stand up, but the ability he had just comprehended could not be retracted freely, the black mist dissipated instantly, and in the exclamation of the two women, Alan put on his clothes in embarrassment.

Fasqi had been in the underground for too long, and there was still a lot of work to be done in Falling Silver City, so she asked Alan to take her back to the regimental headquarters.

Fasqi landed on both feet and got out of Allen's arms: "Remember, this battle is also a test of your qualifications to join the Thirteenth Trial, needless to say, you should do your best." After all, this is a battle that costs lives. I'll give you the right amount of support, but don't expect me to go straight into the fight, this time you'll have to defeat your opponent on your own. ”

"Can I not participate in that tribunal?"

"Can't!" Fasiqi refused without even thinking about it, "Your time is running out, plan well." After Fasqi finished speaking, he walked into the elevator leading to the regiment headquarters, leaving Allen with a bitter face!
