Inside the furnace is an egg-like incubator, with no tissues made of blood vessels or proteins, but instead of countless unnamed clusters of light.

When Tang Xiao swam his body and didn't get close to the incubator, a transparent barrier stopped it.

No matter how you move forward, you can't squeeze through.

"Welcome to the experimental subject Tang Xiao and enter the main god exchange shop." A prompt sound came into Tang Xiao's mind at the same time.

Exchange?

Tang Xiao's heart moved.

I opened the exchange interface from the system in my mind, and it was full of ......

Check the annotations in the footer, but there are tens of thousands of pages!

However, after observing for a while,

Tang Xiao had already discovered the doorway of the main god exchange system.

According to the index, it can be basically divided into five categories:

"Limb Alienation, Basic Enhancement, Special Treasures/Equipment, Quest Scrolls, God-level Exchange."

"Limb Alienation:

As the name suggests, it refers to the exchange of different limbs of various creatures in the exchange system, and the fusion and alienation of their own bodies.

The options in the drop-down menu are all of these, and the rarity seems to be distinguished by color -

Common creature limbs such as African elephant legs, rhinoceros skins, frost wolf front paws, insect armor, snake eyes, etc., are only pale green logos.

And further up, there are: mutated pit vipers and scales, triangular monsters, mutated giant frog gills...... This category is marked in red.

"It's too expensive, the cheapest green ones cost a few hundred evolution points, and the red ones cost thousands."

Seeing this, the initial expectation and joy in Tang Xiao's heart were already half cold.

Look up at the bright gold logos:

Dragon's wings, Malu's armor, Stingworm's jet, Blade Queen's core......

They are all tens of thousands or hundreds of thousands of evolution points! Not in stock yet!

Not to mention the high price of these limbs, the tips behind it are even more like a black-hearted boss who can't pay for his life:

"The Three Laws of Alienation:

Tip 1: There is a risk of alienation, if the gap in the gene chain is too large, it is very likely that the gene will collapse and die. (The danger of non-racial species has increased dramatically!) ）

Hint 2: Alienation does not determine the preview result, and the new skills generated by the original skills and the changes in the limbs after the alienation are unpredictable.

Hint 3: Depending on the meltability and potential of the subject's body, the effect will increase or decrease. ”

Tang Xiao sighed in his heart and continued to scroll down.

"The basic enhancement column is very simple, that is, it costs evolution points to strengthen your own quality.

There are a total of six items, which are mental strength, cell vitality, nerve reaction speed, muscle tissue strength, immune strength, and energy body storage/recovery improvement.

Psychic power is supposed to be used to defend against attacks from animals and plants that can produce psychedelic gases, or from higher-level illusions, wild, fantasy, and mythical subjects.

Cell vitality should be the body's ability to recover, the stronger the cell vitality, the faster the recovery speed after injury, and even the ability to regenerate with broken tails like earthworms and geckos!

With the improvement of nerve reflexes, you can have faster reflexes, and you can see objects moving at high speed or attack tracks.

And in addition to this, it is the strength of muscle tissue. The greater the strength of the musculature and the strength of the body, the speed of the flesh will increase at the same time.

Finally, immunity and energy body, immunity can strengthen resistance to venom, viruses, etc., while energy body is to increase the storage and recovery of energy in the demon core in Tang Xiao's body now.

"Compared to limb alienation, basic enhancement is crude and effective, and it's not too expensive, 100 evolution points and 1 trace ......"

Tang Xiao did not rush to choose, but continued to look back:

Special Treasures/Equipment, there is another option in this column, which is to sell to the main god.

But overall, the price is still at least 1/3 lower than buying from the main god.

There are not many treasures and equipment in the column, there are some such as explosives, improvised machine guns, spear axes, humans, and beasts that have evolved limbs, and more are such as the Sharoman snake demon core in Tang Xiao's body, dragon crystal, and even some immortal birds that appear in the Eastern World.

Again, the higher you go, the more expensive it is.

Even the Sharoman Snake Demon Crystal in Tang Xiao's body was worth nearly 3,000 evolution points, which was far from being consumed by an experimental subject who came out of the main god paradise for the first time.

Finally, the god-level exchange interface is locked with a black lock, which prompts that the gene chain will be opened when it reaches more than 70%.

The quest scroll is to pay different evolution points to exchange for different levels of tasks, and when you reach the reincarnation plane or the main god paradise where the task is located, there will be special guidance and rewards in the system.

It is estimated that the guide ran to the corpse of the Shaloman snake guarded by the Fire Devouring Spider this time, which was a task exchanged from here, but he let himself snatch it by mistake.

That's all for redemption.

The ideal is very plump, the reality is very skinny, Tang Xiao really understood the true meaning of this sentence after roughly browsing and seeing the evolution points he had left!

"Subject: Tang Xiao."

"Evolution Points Remaining: 300."

Even these 300 points were obtained by hunting the flying squirrel in the cave at the end, otherwise Tang Xiao would have had little left when he repaired it for the third time.

"Lord God System, why is there no exchange for related skills?" Tang Xiao asked.

“……”

After a long time, the system voice came:

"No classification."

Tang Xiao's heart suddenly beat wildly.

Sure enough, the expression of the skill is most likely just a cognitive trap used by the main god to guide the test subject.

Each organism naturally has different abilities due to its different structure. If you can exchange it at will at the main god's place, there are two possibilities-

One is that the main god's ability is so strong that it can change the law, and any known theory is bullshit here.

In this way, no matter how much Tang Xiao and these experimental subjects struggle, they are just playthings in the main god's sand table, not even as good as dogs!

The second is virtuality, whether it is their animal body or the various enhancements they obtain, they are just virtual electronic signals to stimulate the brain.

But this contradicts the previous speculation.

Therefore, the main god is in the skill, not that it doesn't want to set it, but there is no way to set it at all, whether it is alienation or using evolution points to evolve skills, it is based on the mutation or reorganization of the structure of the test subject itself.

Those so-called "cooldown, duration, ......" and other skill descriptions, in the original cognition, will think that there is a description first, and then the skill will evolve.

"But it's actually an advanced skill, and then the main god system will scan it and get a quantitative conclusion!"

Tang Xiao's eyes flickered.

Don't look at it as a small problem one after the other, but it is an important clue to whether you can get rid of the control of the main god in the future!
