For the next half day, Li Ang has been in the alchemist's workshop to perform physical fitness tests such as return running, bench press, squat, and forward flexion flexibility.

Miss Chai put on the white coat that Li Ang burned to her, put on the researcher's glasses, held a pen and paper, and recorded various data of Li Ang's physiological functions in real time through the multi-parameter portable monitor purchased by a certain treasure, as well as various instruments that Li Ang had taken out of the underground laboratory of the distortion world.

ECG, EEG, core temperature, skin temperature, nerve conduction velocity, blood pressure, blood oxygen saturation, oxygen consumption and oxygen debt capacity, sweat metabolism, lactate accumulation...

Combining the physical fitness test results with the physiological parameter data, Li Ang continued to tinker with the original foundation, patch the loopholes, and improve the details.

For example, increasing the area of villi in the olfactory mucosa to increase the density of the olfactory nerve.

increase the area of auditory hair cells,

Strengthen the toughness of ligaments, adjust the arrangement of collagen fibers of knee cartilage,

Modify the fingerprint pattern,

Strengthen hair follicles, so that hair and hair are not easy to fall,

Enhance the heat dissipation function of sweat glands,

These modifications are relatively basic, relatively hidden, and not easy to detect anomalies.

Out of secrecy and species complex, Leon still retains his human form.

It's just that due to changes in bone weight, muscle density, and the number of organs, Leon's weight has skyrocketed, which is seriously inconsistent with his appearance, but as long as he pays more attention to it, he should not be noticed.

The human body is too small, and the narrowness of the space level determines that it is difficult for the human body to carry more functions.

However, there is still a huge potential to be explored.

For example, Leon's own human body is seen as a large machine composed of countless parts, cultivating a variety of organs with different functions.

For different environments, take out all kinds of organs, plug and play.

An arm that can discharge electricity like an electric eel,

Ears that can be echolocated like bats,

Like highly specialized flies, super-large membrane wings with asynchronous muscles that can tremble at ultra-high speeds,

glands that spew a pillar of fire like a Western fire dragon (double glands that spew butane on one side and high-pressure gas on the other),

Green skin that can photosynthesize like a plant,

Fins, gills, tails, venom glands...

During the battle, other players take out various equipment items from the backpack slot.

And Leon took out his eyes, ears, arms, thighs, and wings from the backpack bar, and installed various organs on his body like assembling Lego bricks....

It's a beautiful picture when you think about it.

But the ideal is very plump, and the reality is very skinny

At present, Li Ang's transformation of his body can only be done here, and he can't go further for the time being—even if he cultivates specialized organs, his brain can't directly adapt to it, and command it like an arm.

If there is a problem with the limbs and torso, you can still use the [Micro Life Potion] to cover it, and if there is a problem with the brain, it will be over.

"For more and more exaggerated transformation schemes, you have to try your hands with other animals, hypotheses, conjectures, experiments, demonstrations, and explore step by step."

Li Ang muttered to himself and took out the [Automated Pet Breeding Box] from the backpack bar.

The three-meter-long terrarium is filled with blood water that has been poured out of the bathtub, and it is clear that it treats the human cells and bacteria in the blood water as the main feeding organisms, and automatically simulates the temperature and humidity that are most suitable for cell growth.

Li Ang took some blood water, saved the sample, and paid 1,000 game coins to upgrade the [Automated Pet Breeding Box].

After upgrading, the quality of the terrarium is still at the rarity level, and the appearance has not changed, but the height of the blood and water inside has plummeted, leaving only a small puddle, piled up in the corner.

"Is that a tenfold reduction in the scale of space?"

Curious, Leon lifted the lid of the glass and poked his head to look down, revealing that the interior had become a large space 30 meters long, 20 meters wide, and 15 meters high.

"600 square meters, which is slightly larger than a basketball court, is enough space."

Leon thought about it, took a small piece of pork from the refrigerator, and tried to throw it into the breeding box, but found that the pork could not be thrown in directly.

Instead, you have to hold it in your hand, press and hold the glass lid of the terrarium at the same time, and spend dozens of seconds entering a state of fugue, using your mind to transfer the pork directly to a certain place in the terrarium.

Come to think of it, the name of this piece of equipment is [Automated Pet Breeding Box], and now the height difference inside is 15 meters, which is enough to kill a lot of animals if you throw it directly.

Leon experimented again, and found that dead objects such as fertilizer, soil, and kitchen knives could also be teleported in.

And when you want to take it out, you also have to hold down the surface of the terrarium and take it out with your mind.

"If a dead thing is okay, what about a living thing?"

Leon went downstairs, pretending to scatter, caught a few mosquito birds in the community, and after returning upstairs, he experimented again, and found that living creatures, including himself, could also be teleported back and forth.

However, it seems that only the owner of the [Automated Pet Crateum] itself can enter and exit at will, and even if the animals inside have the consciousness of wanting to leave, they can't leave.

"If you don't have close to a minute of reading time, this terrarium can be used as an oversized backpack."

Li Ang went downstairs and got on his bicycle, and came to a deserted countryside outside Yin City overnight, and with the help of Miss Chai, he dug up a lot of all kinds of soil, grass and trees, and put them all into a pet breeding box.

The teleportation effect of the terrarium does not work for the parts that are connected to the whole.

For example, Leon can't touch the ground of the road with one hand and the terrarium with the other, and then pack the whole road into the box.

The road had to be lifted in its entirety to separate the road from the dirt below.

Otherwise, this item is too powerful - if a player wants to destroy the dam, they can go directly to the underground parking lot and use the teleportation effect of the chest to dig up the dam foundation and let the flood break the dam.

In addition, the terrariums cannot transport animals that are moving at high speeds, for example, if a tiger pounces on Leon, Leon cannot reach out and touch the tiger's hair to put it in the terrarium, and the animal must be kept still.

There were so many of them that it took Leon a night to figure them out.

Later, he took a lot of water from a certain stream, put it into a breeding box, cleaned up some dirty clothes, and returned to his home in Yinshi.

In the next few days, in addition to going to school normally, Li Ang soaked in the [Automated Pet Breeding Box].

He constructed a forest with a small pond in the terrarium, with mainly trees, but also a few shrubs and herbaceous plants.

Animals, small birds, small rodents, earthworms, slugs, snails, crabs, mussels, snails, locusts, cockroaches, flies, grasshoppers, mosquitoes, beetles...

Even if the [Automated Pet Breeding Box] has a powerful special effect, it is difficult for the ecosystem inside to reach the level of infinite circulation, and the animals and plants are eliminated and die.

The earth's current prosperity and ecology come from the extremely high fault tolerance rate and infinite possibilities brought by the long time span and huge space.

The time flow rate of the [automatic pet breeding box] is consistent with the outside world, and the internal space is only 600 square meters.

It is difficult to build a circular ecology in which many species thrive.

Fortunately, the essential purpose of Li Ang's use of [automated pet breeding box] is not to create an ecological park for himself.

His sole purpose in constructing the ecological environment inside the terrarium is to explore the infinite possibilities of the [Damaged Biological Master].
