In the next few days, Lin Yi first went to the Avengers Building, and used his Avenger authority to ask Tony for some super-large iron balls that were specially used to test cranes, as well as equipment such as the super-heavy boxing machine that Hulk had used before.

After that, Lin Yi ordered a batch of oblique square rebar, and personally started it, weaving these steel bars with a diameter of 40mm into bundles like weaving twists, and then cutting them with sword qi and welding them with heart fire, hand-creating a cat climbing frame made of pure steel.

By the way, the special attributes attached to the little black cat not only greatly enhanced Lin Yi's attack power when using attribute weapons, but also enhanced all his attribute abilities.

Including the transformation of the five organs and five elements of the chicken ribs before.

Xinhuo, who used to be barely able to light a cigarette, can now even weld steel.

This couldn't help but make Lin Yi feel emotional.

Sure enough, exploring the system is king!

If he was allowed to cultivate by himself, if he wanted to cultivate his heart fire to this point, it would take at least ten years of effort.

Another week passed, in the underground martial arts training ground.

Lin Yi waved his hand to extinguish the fire that ignited in his fingertips, pressed the red-hot weld with his hand, then turned around and clapped his hands at the little black cat who was grinding its claws with an abandoned vehicle.

"Come and see, your nest is repaired!"

Hearing Lin Yi's voice, the little black cat grinding its claws made a move, its two ears were erected in a daze, turned to look at Lin Yi, spread its four calves and ran towards Lin Yi.

Bang! Bang! Bang –

The momentum of the little guy's running is quite extraordinary, that is, stepping on a pit under his feet.

Lin Yi frowned when he saw it, and immediately turned his face flat, and the little black cat that was running was suddenly startled, and hurriedly braked on all fours, plowing a few ravines on the ground, and honestly walked towards him with light cat steps.

"Meow~"

Looking at the flat ground in the second half, Lin Yi nodded with satisfaction, picked him up after the little black cat approached, and put him into a castle-like cat kennel made entirely of steel.

Lin Yi doesn't know if there can be a filial son under the stick, but this can indeed raise a poor Qi.

These days, Lin Yi has used severe sword qi punishment, coupled with the temptation of eggshell food, so that this ignorant poor Qi has a preliminary understanding of what rules are, and also makes him understand that this world is not what he wants to do.

At the beginning, when facing the stinging sword qi, the little black cat looked very aggrieved, and kept meowing at Lin Yi, and Lin Yi was almost broken through the defense line by this little guy, and he passed the test.

But when he thought of the huge power hidden in its small body, Lin Yi still hardened his heart and taught it how to restrain his strength with the most severe means.

But even then, the restraint on power can only be maintained as long as it is sane.

As long as its emotions were a little excited, it would immediately forget all of Lin Yi's teachings and unscrupulously vent its strength as it did just now......

"Alas, there is still a long way to go on the road of education!"

Lin Yi sighed in his heart, and at the same time let go of the hand holding the little black cat.

On all fours, the little black cat suddenly changed from quiet and well-behaved to lively and active.

A small round head arched everywhere in the steel cat's nest, sniffing left and patting right, and from time to time it opened its mouth, leaving bite marks on the protruding city wall with its sharp little tiger teeth.

Well, it's already pretty good, at least not to tear your own cat kennel to pieces like the last time.

Lin Yi showed a satisfied smile on his face, took a step back, and carefully observed the little black cat's follow-up movements.

In these days of being with the little black cat, Lin Yi has basically determined its origin.

This is a new life born from the original Qiqi, with a new and blank soul, and although it has many inherited memories in its mind, its soul has not merged with these memories.

This means that it is a completely independent and new entity.

The inherited knowledge that belonged to the past generations of Qiqi has been transformed from a inherited memory that can affect the soul and personality to a library that only exists in the mind of the little black cat.

It was able to consult the information anytime, anywhere, but it could not understand what it meant.

Lin Yi guessed that the system may have cut off the influence of inheritance memories on the little black cat at the spiritual level, which caused the little black cat's mind not to grow rapidly, and became a 'newborn' poor qi exactly like the previous dynasties.

For this result, Lin Yi is generally satisfied.

Although he always thought in his heart that the arrogant and domineering black-winged tiger before was the pet that best suited his aesthetics, but in the face of the little black cat's milky call, Lin Yi still fell unconsciously.

Just look around.

Cat litter box, steel wire toothbrush, steel cat climbing frame, steel cat nest, titanium alloy cat scratcher......

Ahem, although the materials used in these things may be a little special, the heart that belongs to the novice cat dad is still the same.

After the little black cat was completely familiar with this new cat nest, Lin Yi reached out and picked it up from the cat nest, then put it into his arms, and stroked its head very skillfully.

"Alright, it's time to train."

The little black cat reluctantly glanced at the cat's nest, raised its head again, and meowed at Lin Yi.

"What do you think, your nest is so small, how can I sleep?"

"Meow~"

"No, you've dismantled my two beds!"

"Meow ......"

The little black cat lowered her head in some frustration.

It already understands Chinese, but it doesn't understand some modern terms.

"If you want to sleep in a human bed, then learn how to restrain your strength."

Lin Yi patted its little head lightly, ignored its cry of protest, and raised his foot and walked towards the super-heavy fist machine.

These days, Lin Yi feeds the little black cat with eggshells every day.

After each feeding, he will also habitually open the pet panel to see the increase in the satiety of the little black cat...... Then he was amazed to find that these pure black eggshells could not only increase the satiety of the little black cat, but also give it long experience.

It's no wonder he had 11 XP when he first opened the pet panel.

I thought that it should have been when Lin Yi was digesting and feeling that he had stolen a lot of eggshells.

In just a few days, most of the eggshells that were not many were eaten by the little black cat, and its level was naturally increased by one level, and all attributes were improved.

“

”

I have to say that the little black cat's talent is indeed strong enough, every time it is upgraded by one level, not only its own attributes will increase, but also the inheritance of Lin Yi's attributes will become a little larger.

Lin Yi roughly calculated that when the little black cat ate all the inventory in his hand, he should be able to upgrade by one level.

It is foreseeable that it may not be long before this guy's basic attributes may surpass him.

"It's time to cultivate."

Thinking that he might not be able to beat his pet in the future, Lin Yi felt a sense of urgency in his heart.

Coming to the side of the super-heavy boxing machine that had been hammered by the Hulk before, Lin Yi let go of his hand, and before the little black cat in his arms landed, two black mist sprouted from its back and turned into two black wings.

After more than a week of special training, the little black cat has been able to skillfully use the black mist on its body, and can also transform its two wings into black mist, and then put it into its body.

Even Tony and Banner would never have recognized it if they hadn't been up close, and this seemingly ordinary little black cat was the ferocious and arrogant black-winged tiger of the Rocky Mountains that day.

Call! Whew-

Flapping wings, whistling air currents wrapped around the little black cat's body, enveloping it and flying forward.

The clouds are from the dragon, and the wind is from the tiger.

Although Qiqi is not a real tiger, he still has some ordinary ability to resist the wind.

With the help of wings and airflow, the little black cat flew very smoothly in front of the super heavy boxing machine, gently raised the forefoot with a pink meat pad, aimed at the titanium alloy target on the boxing machine, and then slapped down violently-

Bang –

The air suddenly exploded, and the 25-ton fist machine shook, and the value on the electronic screen began to rise wildly, and finally stopped at the value of 15,381 pounds.

If you convert it a little, it's about 7 tons of power.

"Meow~"

The little black cat raised its paws, turned its head and barked at Lin Yi.

Lin Yi nodded as usual.

"Go on."
