Burn vitality and enhance mental strength!

It was like a flash of lightning struck Yin Lai's brain, making him sober up all of a sudden.

"No way?" Yin Lai turned around and looked not far away. The withered mouse was still lying in the pile of rats.

When he was still a little half way away from the potion, his potion seemed to have changed a little.

Yin Lai is an immortal. Of course he has done some experiments on himself this year. The clearest perception is that of immortality. His most direct expression is that his vitality will not be consumed.

If the magic potion in front of me really only consumes vitality, it can increase mental strength.

Then he can directly declare that this experiment was a success.

Gulu!

Yin Lai took a deep breath and immediately reconfigured the potion. It might be a sleepless night today.

…

Three days later!

In the laboratory.

"It's really successful, it's successful!" Yin Lai held a bottle of newly prepared solution in his hand, showing an excited expression.

After experiments, he finally successfully verified the effect of the potion. It actually consumes vitality and improves mental power. Moreover, he found that the most important one is the purple iris. The more you add, the more mental power can be improved.

Yin Lai even verified a specific quantity that can improve the potion to a level comparable to the original version.

"I am simply a genius!" Yin Lai smiled.

Maybe he just didn't think of this route, and Yin Lai never thought about it either.

But today, he somehow managed to create a potion that suited him so well.

But this can't be blamed on him. The notes recorded in Salin Metatlin's notes are all very serious potions. How could it be possible to record the potions that consume the vitality and enhance the spiritual power in the apprenticeship stage? That is simply harmful.

"Today is the time to take the right path." Yin Lai pursed his lips, feeling that a strange path had opened up.

The next step is to experiment, as long as the experiment is successful.

He can take it and start improving his mental strength.

…

Three months later!

at home.

"Almost!" After three months of verification, Yin Lai was able to confirm that the potion had no other shortcomings besides consuming vitality.

Today is the day he takes it.

His current mental strength is at 6.3.

After recording his own data, Yin Lai took out the potion and took it directly.

The moment he took it, Yin Lai felt something seemed to be passing by, and his mental power began to slowly increase. It all happened very quickly and very slowly.

If someone looks at Yin Lai at this time, they will find that he is in a strange state at this time. For example, his hair is turning white little by little, and wrinkles are gradually increasing on his face, but every time it only takes an instant, his hair turns black again, and his wrinkles also disappears.

It was not until half an hour later that this change gradually disappeared.

Yin Lai checked again.

Mental strength has become 6.5.

It was directly increased by 0.2 at one time, which is not much. However, for safety reasons this time, Yin Lai only used the ordinary version and did not use the luxurious krypton life-increasing version.

If he really sticks to this range, I'm afraid he can be promoted to a second-class apprentice in a year and a half.

"However, considering the problem of drug resistance and the production cycle, this time will be a little longer. It should be almost two years." Yin Lai fell into thinking.

Please don't do anything with him for the next two years.

…

The passage of time is always fast and slow for Yin Lai.

What is slow is the process, what is fast is when he reaches the next point in time and looks back on the past.

When Yin Lai felt this way again, he realized that two years had passed.

And he is finally about to become a second-class apprentice.

On this day, Yin Lai specially asked for leave.

In the basement.

Yin Lai felt his state, his mental strength was 9.99, and on his right hand was a bottle of Kryptonite No. 1 potion that he had just made. This was the name he gave to the potion.

After all, although it originated from the Deep Blue Potion, in the end it actually had nothing to do with the Deep Blue Potion, and because of its life force-consuming effect, he named it the Kryptonian No. 1 Potion.

"Promote!"

Yin Lai opened the potion directly and took it in one gulp.

The familiar feeling made Yin Lai feel sour again, but the improvement in mental power also made him happy.

Soon, the mental strength exceeded 10 points, and finally stopped at 10.1.

There were no surprises or bottlenecks.

Nonsense, if there is still a bottleneck in being promoted to a second-class apprentice, then Yin Lai's talent cannot be described as garbage, it can be said to be a garbage dump.

"Feeling good." After absorbing the potion, Yin Lai felt the changes in himself.

As he was promoted to second-class apprentice, the elements he could feel suddenly increased a lot, and the elements in his body and his ability to communicate with them were also greatly enhanced.

Of course, this is only the main change. More Tuansu will also make Yin Lai's body tougher. Of course, this will take some time, but just like that, Yin Lai can already clearly feel that he is stronger.

As for how strong it is, that needs to be tested to know.

Immediately, after simply cleaning up, Yin Lai went straight to the secret valley outside the venue.

In the valley.

Yin Lai concentrated his mental power and began to carve mental runes. In just a moment, a huge fireball appeared in front of Yin Lai's eyes.

The fireball was twice as big as the first-class apprentice, and the temperature was obviously much hotter, and the power contained in it was much stronger.

release!

The fireball instantly hit the stone wall not far away.

boom!!

A huge roar sounded, and a fireball exploded on the stone wall not far away. The flames spread instantly, and the power of the explosion directly smashed a large hole into the stone wall, and the rubble flew around like rain.

A wall of wind appeared, blocking these.

In the wind wall, Yin Lai smiled.

This is at least twice as powerful as when he was a first-class apprentice. Coupled with other abilities, his combat effectiveness has soared. Oh, and there is also a staff, which can also increase part of his strength.

"Now, the senior knight doesn't know my strength, but below the senior knight, I'm probably a loser." Although he has never fought against a knight, Yin Lai has his own judgment.

After testing the fireball technique, Yin Lai tested other witchcraft. After obtaining the specific data, he left directly.

On the way out, Yin Lai saw that there seemed to be more people than usual in the nearby woods.

"What happened?"

Yin Lai asked a walking man.

"Ah, we just heard a noise over here, so we came over to take a look."

The man was a little surprised to be called suddenly, but he still answered.

"Oh." Yin Lai nodded and left.

He should have put a soundproof circle in the valley. The sound of the fireball explosion just now was indeed a bit loud. Of course, he didn't need to worry about anything. Although there was no soundproofing, the concealment there was enough, and there were other hiding methods, even for high-level ones.

Don't expect the knight to find anything.

There were many people heading in that direction. Yin Lai even saw a group of knights from King's Landing, but they just glanced at Yin Lai and ignored them.
Chapter completed!
