After finishing dinner as fast as he could, Lin Cheng said hello to Daisy and Bai Ling, and then ran back to the bedroom on the second floor and closed the door.

Sitting on the bed, Lin Cheng took a deep breath, then slowly exhaled, and after stabilizing his mind, he saw that a silver metal capsule suddenly appeared in his hand, and there was a faint noble charm under the reflection of the light.

Gently pressing the switches at both ends of the capsule, as a glass bottle appeared in his hand, Lin Cheng raised it and found that the liquid inside was not the same as the previous strengthening liquid, faintly blue, under his slight shaking, the blue liquid in the bottle flashed and flashed, as if there was a silver filament mixed in it.

He didn't suspect that this thing had gone bad or had been manipulated, after all, it had just been exchanged from the capsule system and hadn't even been a minute away, and the reason why the color had changed was probably related to the model.

Judging from the number of the enhancement agent, the enhancement agent that the capsule system can provide is divided into five grades from E to A, and the EDC-level enhancement agent should belong to the low-end product in the judgment of the system, so there is no difference in the color of the agent, all of them are white transparent liquid.

Starting with the B-type strengthening potion, the color of the potion suddenly began to change, and this change probably means that he has left the middle and low end and began to enter the ranks of the high-end powerhouses recognized by the system!

After thinking for a while, Lin Cheng unscrewed the cap of the bottle, and after taking one last look at the blue liquid in the bottle, he tilted his head upwards and poured the entire bottle of enhancement liquid directly into his mouth with a "grunt"!

"Hmm...... Seems a little sweet? ”

After drinking this bottle of B-type strengthening potion, Lin Cheng smashed his mouth and found that this thing was really different from the previous one, not only the color had changed, but it also had a taste.

Swallowing a full 50 million energy points in one bite, it would be false to say that he was not distressed, but after all, the strengthening potion is the foundation of his survival in the last days, let alone 50 million, even if it is 500 million, he has to find a way to make up the energy value and exchange it.

"I don't know how effective it is......"

Finding that there was no reaction in his body after swallowing the strengthening potion, Lin Cheng frowned, jumped out of bed and did a set of stretching exercises, before he would quickly fall asleep after taking the new strengthening potion, but this time he didn't know what's wrong, he did several sets of warm-up exercises in a row, but his mind was still very clear, and he didn't feel like he was going to be unconscious at all.

From the moment he discovered that the color of the Type B enhancement potion had changed, what had happened since then had rendered his previous experience useless, and now he could only slowly explore the mysteries as he had done at the beginning, and there were no shortcuts for him to take.

However, being able to exchange for Type B Enhancement Elixir had already made the stone that had been hanging in his heart for a long time fall, and although he was sure to exchange for Type A Enhancement Elixir, he didn't even bother to think about it.

The changes brought about by each upgrade of the capsule system are relatively fixed, for example, when level 0 is refreshed, there are drugs such as enhancement potions, so when you are upgraded to level 1, you will not refresh new medicines, but will refresh auxiliary supplies such as houses, and if you want to use new enhancement potions to improve your strength, you need to upgrade one level to level two to exchange for refreshed D-type enhancement potions, and the same is true if you want to exchange upgrades such as houses.

The advantage of this cyclic refresh method is that each upgrade allows the host to have a new choice without feeling overly stressed, but the disadvantage is that the energy value required for each new enhancement potion refreshed is 100 times the price of the previous level of the potion!

The pressure brought by the hundredfold price is not very obvious in the early stage, and even if it is difficult to transition from 500 energy points to 5,000 energy points and then to 500,000 energy points, it is acceptable as long as you work hard, but starting with the B-type strengthening potion, the demand for up to 50 million energy points is not only enough for hard work, but also requires good luck and time.

Lin Cheng thought that his level of effort and luck were very good, but it still took more than half a year to be able to get together the 50 million energy points, and if he wanted to exchange for the top existence in the capsule system of Type A Enhancement Elixir, the energy value required according to the refresh rules of the system would be an unimaginable 5 billion points!

What is the concept of 5 billion energy points?

An existence like a Frost Giant Jiao provided him with less than six million energy points, and in order to make up the energy value for the exchange of Type A enhancement potions, he needed to kill more than 800 monsters of this level to make up enough, and he almost gave his life there in order to kill that Frost Giant Jiao before.

Of course, in addition to the BUG-like monsters like the Frost Giant Jiao, there is also the existence of the Giant Wolf Leader, which is not strong but has a rich net worth, but Lin Cheng knows in his heart that the existence of the Giant Wolf Leader is strictly speaking, just like the Frost Giant Jiao, it is one in ten thousand.

Let's not talk about the Frost Giant Jiao, as an ancient fierce beast, Lin Cheng was able to meet two heads completely because of his bad luck, let alone ordinary people in a lifetime, I am afraid it will be difficult to encounter it once in ten lifetimes, and even if it does, it will not survive at all.

And the reason why the giant wolf leader became like this is because it has eaten too many mutant beasts, after devouring such a large number of mutant beasts in a short period of time, even if its strength is not as strong as Lin Cheng, it is already an invincible existence in front of other people or monsters.

However, the conditions required to become such an existence as the leader of the giant wolf are extremely demanding, and the right time and place are indispensable, so it can be said that even if the leader of the giant wolf wants to replicate such a success, the chance of success is extremely slim.

And the so-called weakness is only relative to Lin Cheng, even if others are as strong as Bai Ling, they will be injured a lot under the blow of the other party, it is conceivable that if it is not for the bad luck to meet Lin Cheng, such a pervert, it is estimated that it can still run rampant in that primeval jungle for a long time.

Because he knew this, Lin Cheng had basically acquiesced after exchanging the Type B Enhancement Elixir, at least in one or two years or even three or four years, he would not be able to make up enough energy to exchange for the Type A Enhancement Elixir, so he didn't plan to bother about this matter anymore, just let it be.

Glancing at the dazzling 18 energy points on the existing energy value interface, Lin Cheng bared his teeth, and his heart was always a little unsteady, the energy value was like the effect of money on everyone before the end of the world, no matter how much or less, he always needed a little savings to be sure, these 18 energy points could not even be exchanged for the lowest capsule, and it was indeed a little uncomfortable for him who was used to sitting on tens of millions of energy points.

However, as long as you are willing to work hard, this thing can quickly accumulate again, shook his head and didn't think about it anymore, and waited for a while, feeling that there was still no reaction from all over his body, Lin Cheng could only give up helplessly, walked into the bathroom and washed up, then went back to bed and went to sleep.
