casually took out a bottle of physical strength potion and poured it into his mouth, Qiao Yuchen slowly sat up, this promotion made him feel great pain, of course, the result was good.

At the moment, he was a little annoyed, and called for the system in his heart.

"System, what kind of yarn are you doing, why is there no pain in Chen Xiao's promotion, and my brother and I will suffer this catastrophic pain when I am promoted?"

Fortunately, the system did not fall silent, otherwise it is estimated that Qiao Yuchen would be even more annoyed, but although the system answered, the answer did not make Qiao Yuchen happy.

"Drop, as an apocalypse, can do what others can't, become what others can't, if you want to be strong, you must first suffer from it, only if you understand the pain, you will cherish it more, and you will work harder to make yourself stronger..."

"Poof..."

Qiao Yuchen, who hasn't vomited blood for a long time, really wants to vomit for a few days and nights now, what the hell is this. What does it mean to be able to do what others can't, to become what others can't, and you must suffer from it first, do you think it's "Born in Sorrow and Died in Peace" in "Mencius".

"I said system, emotional awakening to become an apocalypse is to endure hardship? Don't you tell me that this will be the case in the future? ”

To be honest, Qiao Yuchen was really a little scared in his heart, you must know that when he was promoted, the pain for that period of time was really not something that ordinary people could bear, and he didn't know how he survived.

"Drop, host please rest assured..."

Hearing the system say this, Qiao Yuchen was relieved, but the next moment, he was not calm.

"Drop, the pain of the Apocalypse will double with each promotion..."

Crit, 500 Hits, Floating, Crit, Combos, Million Crits, Floating.....

Qiao Yuchen felt that the whole person was like a boss in the game at this moment, unable to fight back and being hit by the player with combos, and constantly hitting high-intensity critical hits.

"System, let's discuss, can I change careers..."

Qiao Yuchen really only wants to die at the moment, such a double of pain, what is the concept, the key point is not here, but every promotion is double the last time. What a notion this is. If you advance to level nine one day, the pain index alone is estimated to be able to ruin this world.

In the face of Qiao Yuchen's request, the system: "......"

Qiao Yuchen sometimes thinks about what good this Apocalypse can be, making himself like this, all this really makes him very sad, and now he has no way to change all this. It's really like a dead heart.

Silently accepting this reality, Qiao Yuchen calmed down, he needed to check the situation of the system.

"System, what has been upgraded, let's show it."

"Drip, please manually upgrade the host..."

"Huh?"

Qiao Yuchen didn't expect that the upgrade would need to be manually upgraded. A picture popped up in his consciousness, showing the word upgrade, and Qiao Yuchen clicked on it without hesitation.

Qiao Yuchen waited for a long time, but there was no movement, and the picture of gorgeous special effects in his imagination did not appear, and Qiao Yuchen was embarrassed for a while. Feelings, my imagination is a little too rich.

Then the sound of the system rang out.

"Drop, congratulations on the upgrade of the host, the current level is disciple, open known level masters..."

"Drop, add a two-star evolution potion with an exchange price of 5,000 (Level 3 crystals), a new Ability Elixir with an exchange price of 100 (Level 2 crystals), a new special healing drug (intermediate) with an exchange price of 120 (Level 3 crystals), a new Life Skill Book, with an exchange price of 5,000 (Level 4 crystals) ......"

"Drop, trigger the mission, fight to save humanity (mission uniqueness)..."

"Mission content: The survival of mankind is at stake, develop the Dawn Base, make the base a utopia for everyone's survival, and establish its own World Peacekeeping Force (Human World Peacekeeping Force),"

"Reward: Otherworldly Teleportation Destruction Device."

"There is no time limit for the mission, the mission is not completed, the human race will be extinct, fight for the human race, attack, young ......"

Seeing the task released by the system, Qiao Yuchen really had a dark face: Why is this still related to maintaining the world, and what the hell is the teleportation port of the other world? And the most critical thing, the last slogan of such a middle two, system, what do you think, you come out, my brother promises not to kill you.

Qiao Yuchen was extremely depressed in his heart, and the slightest excitement that was originally generated by the upgrade was directly extinguished by the system's task.

And this mission also made him realize one point, the great crisis of humanity.

Slowly calmed down from the depression at the beginning, and found a lot of problems from the tasks released by the system.

First, the current living conditions of human beings are far from what they are looking like in front of them, and there is a deeper crisis behind them.

Second, the reason for the emergence of these alien creatures today is the so-called otherworldly teleport, which shows that this is basically a struggle between the two worlds.

The third is where Qiao Yuchen's face is the darkest, it seems that he has become a turning point in the survival of human beings in this world, and he feels inexplicably that Yali Mountain is ......

Fortunately, the system did not say that it would enter a serious period now, at least he still had time.

"Whew......" Qiao Yuchen exhaled deeply, and this breath felt very uncomfortable in his chest.

"Let's take a look at the newly opened exchange first."

Qiao Yuchen silently clicked on the exchange system, and the screen on the second page was displayed.

There are more two-star evolution potions in the second grid of the first row, which means that everyone, including themselves, can be upgraded to level three, which is good news for them now.

"Well, it seems that a large number of tun crystals are needed, otherwise everyone's strength will not be able to improve quickly. Only when the strength goes up, there will be more and more money, and the more money there is, the more security will be. ”

Qiao Yuchen sighed, he was worried about money before the end of the world, and he was still worried about money after the end of the world. The world is really as as ever.

Looking down, there are two more slots in the second row, which are Ability Potions and Special Healers (Intermediate).

The effect of the special treatment medicine (intermediate) is already known, but the price is not so friendly, 120 third-level crystals, this is not a joke. But it's also said in the past, after all, the effect of intermediate treatment drugs is there. That's not a little bit higher than the lower level.

Ability potion, needless to say, should be similar to the effect of the previous power potion, now it is really unnecessary for them to use it, the effect of the power potion is there, the higher the level, the more bonuses, and the second time you use it, the effect will be reduced a lot, and the most suitable is to use it again when the level is high.

The gaze fell to the third line, and in the first compartment was the life skills book. Looking at the name, Qiao Yuchen could already imagine that this should be like in the game, what kind of weapons are built.

It's just that he doesn't know if this life vocational skills book can be used by others, and now he can't exchange it for a look, after all, the price is too unfriendly.

Five thousand... Fourth-order crystal...

Qiao Yuchen had the urge to scold his mother, but he couldn't help it when he thought about it, this was not his personality. Of course, he is not the only one who knows in his heart.

Now that he has been promoted, his level has also increased, and a lot of new items have been opened, which makes Qiao Yuchen full of new hopes for promotion, of course, except for the pain that needs to be endured to advance. There are also potions that need to be doubled to advance.

The Apocalypse was promoted again, and the quantity he needed was ten bottles of Awakening Elixir and ten bottles of Two-Star Evolution Elixir, which means that the consumption required to advance again was three million energy points, as well as 50,000 third-level crystals....

Thinking about Qiao Yuchen, he feels terrifying, he is a bottomless pit, if he is promoted to the ninth level... He couldn't even imagine it.

However, this is only the beginning......
