Shi Yan took several deep breaths before slowly calming down and asking, "Who are you?" ”

"I'm the strongest digestive system ever." A voice sounded in Shi Yan's mind.

Shi Yan turned his head to look at the few bank clerks and passers-by who were still busy, and found that they didn't react at all, obviously they didn't hear anything.

"What is the strongest digestive system ever?" Shi Yan was a little blindsided.

The voice in his head slowly explained to him.

It turns out that this is known as the "strongest digestive system in history", no matter what matter or energy, it can be decomposed and absorbed, and finally the owner of the system can be strengthened through the absorbed energy, that is, Shi Yan.

Shi Yan felt the powerful benefits for the first time just now, if it wasn't for the red mist that strengthened his body, then he would end up either like a person lying in a pool of blood, or like a middle-aged man kneeling on the ground.

Now that he had the strength, the blonde young man and the three of them were lying down, and now they were thrown out like dogs to fend for themselves.

Shi Yan didn't feel much when he hadn't tried the powerful feeling, but after trying it, he would become obsessed with this feeling.

This function of the system is really timely, and you can use it to suck and suck in the future, and you can continue to strengthen yourself.

Shi Yan couldn't help but grin when he thought of this, and smiled like a villain.

But! The next statement gave Shi Yan another blow to the head, this digestive system is like a stomach, it must be fed regularly, otherwise it will absorb Shi Yan's energy.

It's like the stomach, if you don't feed it, it digests itself.

Shi Yan's face was as bitter as a bitter gourd when he heard this, and I also invited an ancestor to come and make offerings every day?

"What is prey? What are you going to eat? Shi Yan seemed to be in a bad mood and said.

"It's okay to be like those monsters, but it's not limited to monsters, and a lot of things have to be encountered to determine whether they are suitable or not." The system voice rings in my head.

"Monsters?" A black line appeared on Shi Yan's head again, isn't he looking for death when he goes to catch monsters now? Who exactly is it fed to? Do you feed the monsters?

"Go on." Shi Yan said in a bad mood.

Listen to the next listen, fortunately, it is not to feed every day, but to feed the prey every fourteen days, as for the prey, it is all-inclusive, but it must meet its requirements, and the system will automatically identify it.

Fourteen days, although the time interval is not short, but if you are trapped by something, wouldn't it be miserable?

For example, when you go to prison and can't hunt your prey, will you be sucked dry by the system?

When Shi Yan asked the system this question, the system just euphemistically said that it believed that Shi Yan could solve this problem perfectly.

Hearing the system's reply, Shi Yan's head was full of black lines, official tone, this is all official tone.

But the system gave Shi Yan hope that when the system was upgraded to level two, the interval between feeding would be increased to twenty-eight days, because the higher the system level, the more cosmic free energy it would automatically absorb, and it would not need to be fed so frequently.

The interval between level 1 is 14 days, level 2 28 days, level 3 56 days, level 4 112 days, level 5 224 days, and level 6 448 days. Level 7 is 896 days, and feeding is no longer required above level 7.

The higher the level, the longer the feeding interval, it seems that only by upgrading the system can you get rid of the trouble of feeding, Shi Yan thought with some annoyance.

As for the system level, it is now the lowest level, up to level nine, and whether it is strengthening the body or refining skills, only the corresponding system level enhancements and skill refinements are made.

This refining skill is another function of the system in addition to strengthening, many monsters have natural skills, natural skills come from the bloodline, and the system can extract the natural skills of monsters from the bloodline of monsters.

Shi Yan touched his nose in disbelief, is this okay?

There is no limit to the energy absorbed by the system, the first-level system can absorb second-level and third-level energy or even higher, but when strengthening the body, it can only produce first-level strengthening, which is limited to the level of the system itself.

If you want to perform Level 2 enhancement or refine Level 2 skill shots, you need to upgrade the system to Level 2.

"Then it's useless for me to get higher-level prey, you are only level 1 now, and the enhancement can only be a level 1 enhancement?" Shi Yan asked.

"This is not wasted, the energy in the high-level prey has not been completely released, and when you carry out second-level or even third-level enhancement in the future, the energy in it will continue to be released."

It seems that in order to exert the effect of high-level prey, the system can only be upgraded, so that the second-level or even third-level reinforcement can be carried out.

The system paused, as if waiting for Shi Yan to digest the above information, before continuing: "And even if it is a first-level enhancement, there is a difference, the high-level prey gives you the top-level first-level enhancement, while the ordinary first-level monster can only give you the ordinary first-level enhancement, and the difference between this is sometimes calculated in multiples." ”

It turned out that there were so many differences in details, Shi Yan thought to himself that this was reasonable, could it be that the final strengthening results of the third-level monsters and the same first-level monsters were the same? It's simply impossible.

And to level up, you need experience points, which will generate experience points when absorbing energy and refining skills.

But there is one point, the repeated process does not produce experience points, for example, if you absorb the energy of a monster, you will have no experience points when you absorb the energy of the same type of monster next time, and the same is true for refining skills.

"How many XP points do I need to level up?" Shi Yan is most concerned about how to level up, which not only means that it is powerful, but also means that he does not need to be fed frequently.

"Level 1 to Level 2 costs 100 XP, Level 2 to Level 3 costs 200 XP, Level 3 to Level 4 requires 400 XP, and so on."

Shi Yan took out his mobile phone in his trouser pocket, but fortunately it wasn't rotten from the fight just now.

There's a monster network on the Internet.,Basically, the monsters that appear will be included in it.,Try to connect to the Internet.,You can connect to it.,Open it and take a look.,Sure enough, there's a detailed introduction to the monster.。

Shi Yan counted carefully, so far there are only twelve kinds of monsters that have appeared on the earth?

So little? This was the first thought that popped into Shi Yan's mind.

I checked the experience points against the system again, and except for one of the winged dragons, which had three experience points, the other eleven monsters were all one experience point.

Even if Shi Yan has the ability to kill all the monsters that appear on the earth now, he will only have fourteen experience points when he is full.

After all, killing a hundred monsters is a completely different thing than killing a hundred monsters.

And these twelve monsters are not all over the streets, like the winged wyvern only appeared once, or in Africa, and has not been heard of anywhere else since.

Want to earn 100 XP by killing monsters? Shi Yan couldn't help but shake his head, there are only twelve kinds of monsters appearing on the earth star now, how can there be a chance to make up enough experience points for a hundred points, and it is far from enough to kill them all.

It seems that the road to upgrade this monster is not easy to walk.,How many repeated monsters are played in other people's games are experienced.,How can it be so picky like this system? You have to have different kinds of monsters to have experience points, it's just too perverted.

Shi Yan couldn't help but have a grudge against the system, and he had to be fed again, and it was troublesome to upgrade, why didn't you make it easy?

If you don't upgrade, you have to feed every 14 days? Thinking of this annoying thing, Shi Yan's resentment deepened.

A certain system is secretly laughing.
