"500,000? The price is as expected." Qi Shi muttered as he stood in front of a large cage. Inside the cage was a cow quietly gnawing on the grass.

Although he looks very peaceful and peaceful, his explosively bulging muscles like a knife cutting through rock and his two curved horns can easily overturn a car.

[Name: Qingxi Buffalo

Grade: Bronze

Level: Level 16

Talent: Tenacity (Bronze)]

Toughness: Tough muscles greatly improve the endurance of the Qingxi buffalo, allowing it to endure long periods of high-intensity fighting and running.

"Although the grade is not high, it is enough as a raw material." Qi Shi said with satisfaction.

The Qingxi buffalo, leisurely gnawing on the grass, felt its anus tighten inexplicably.

"Waiter, swipe your card!"

…

"Hmph...hum..." Qi Shi was busy in the operating room, and he smiled rarely and hummed a tune.

With no means at all, he could only buy a ready-made pet as raw material. Although it cost a little more, it was simple and convenient.

Problems that can be solved with money are not problems.

Qi Shi was surrounded by people in white coats, holding scalpels, with blood and flesh flying everywhere in front of them, and in front of them was the already cold Qingxi buffalo with its legs in the air.

The white-gloved hand grabbed a small object that was still beating and pulled hard.

"Hmm... It's a really strong heart. It works just right to neutralize the heart of the mad ape. The muscle tissue is quite strange. Is this a talent for toughness?"

"Sure enough, the method I expected was correct." Qi Shi's eyes reflected a terrifying light as he looked at the shivering dog at the door.

"Ouch~" The dog's body trembled, then he whined and turned around and ran away.

"What a disobedient child, angel, tie him in."

In less than two seconds, the dog, which was tied up like a caterpillar, struggled and was put on the operating bed, his eyes frightened.

Qi Shi said helplessly: "I'm very troubled by you moving around like this. Angel, please give me a sedative."

"Ouch!!" As the dog screamed, a silver robotic hand held a needle and pierced its butt.

The effect of the sedative took effect immediately, and soon the struggling movements became sluggish, and within a few seconds there was no movement.

"I was in a deep sleep, even the anesthesia was spared, well... I didn't plan to do it at all." Qi Shi showed a cruel smile, raised the knife in his hand, and cut open the dog's back.

Although he was already asleep, the intense pain still made Gouzi's body tremble slightly.

"First, forcefully straighten the spine."

The silver fluid covered the exposed spine, and accompanied by a heart-wrenching sound of steel rubbing against each other, the iron spine could not hold out for even a second and was forcibly corrected.

"Okay, just stay still and inject the first-stage super bone potion that you just prepared."

The sharp needle pierced the spine, and the dog rolled his eyes wildly and his body trembled.

Suddenly, the entire spine began to twist irregularly, and ferocious bone spurs grew crazily.

"Huh? Failed." Qi Shi frowned slightly and slid his finger to the left.

The bone spurs that kept trembling and growing returned to the dog's body as if he were going back in time.

[Modification: If you are not satisfied with the current results, you can arbitrarily adjust to a previous time point and revise again.]

"Ah haha, I'm sorry, I'll make it again right now." Qi Shi laughed heartlessly and slowly turned around and returned to the cultivation room.

After more than ten minutes, he walked out with the reconstituted Super Skeleton Phase 1 Potion Type B.

"Okay, let's re-inject."

Ten minutes later…

"Huh...it seems that there is no problem. In the next stage, we will start injecting the first stage of soul strengthening potion." Qi Shi picked up a deep purple potion.

…

…

Strengthen bones, strengthen soul, strengthen muscles, replace heart and some other organs.

Several hours have passed since a series of modifications and enhancements were made.

"Okay, let's inject the sleeping potion R and let it have a good sleep. It will have to adapt to the new body tomorrow."

He casually took off his white coat and threw it aside. Qi Shi's eyes looked a little tired as he sat on a chair nearby and looked at the real-time body monitoring displayed on the computer screen.

【Lord Qi Shi, just leave these trivial matters to me.】

The voice of an angel rang in my ears.

Qi Shi shook his head.

"It's okay. As the master, this is the responsibility I must shoulder."

…

While he was groggy, Qi Shi was heard by a loud howl of a wolf. He rubbed his sore eyes, he almost didn't sleep all night.

When I looked up, I saw the dog jumping up and down excitedly.

"Ooooooo~"

Running and jumping around the operating table.

"Ouch! (I, Iron Man Three, are back again!)"

Qi Shi managed to cheer up and checked Gouzi's condition.

[Name: Iron-spine Jackal (biomodification)

Grade: Bronze

Level: Level 32

Talents: Strengthened Iron Spine (Bronze), Brain Development (Bronze), Strengthened Tenacity (Bronze), Overload (Bronze)]

Reinforced Iron Spine: The modified and strengthened iron spine is stronger than before and can be slowly repaired after damage.

Brain development: Strengthen the brain, improve wisdom, memory, reaction speed, etc.

Enhanced toughness: The toughness derived from the Qingxi buffalo has been strengthened, giving it tougher skin and muscles than before.

Overload: Entering a state of overload, speeding up blood circulation, ignoring the fatigue caused by aerobic activities, and keeping yourself in peak condition for a long time.

At this time, the dog's appearance had changed greatly. His fur was shiny and fluffy, and his eyes were sharp. His body had grown a lot bigger, with a height of 1.5 meters and a body length of more than 2 meters. He could already reach Qi Shi's chest.

Like a warg, there is a thick ring of hair around the neck. When walking, you can see the outline of explosive muscles hidden under the thick hair.

"Were you unable to break through silver? Yes, after all, the materials used are all bronze grade."

"Ouch~"

After enough fuss, the dog excitedly jumped into Qi Shi's arms and licked his face.

"Hahaha, okay, okay, I was afraid you would blame me when you wake up." Qi Shi was almost knocked down while sitting on the chair, smiling and stroking its rejuvenated hair.

"Ouch~" The dog trembled and cried out sadly. It can be seen that yesterday's transformation has brought a terrifying shadow to it.

"Okay, I apologize, but I'll do it again next time." Qi Shi laughed and hugged the fluffy hair on the other person's neck.

Resting his head in the comfortable fur, Qi Shi couldn't suppress his sleepiness, and after a while, he could hear the sound of even breathing.

Seeing that there was no movement from the other party for a long time, Gouzi turned his head in confusion and saw Qi Shi, who was already asleep.

Use yourself as a pillow and quilt and snuggle up.

Peaceful and quiet.

…

Gouzi's upper body was nestled in Qi Shi's arms, and his lower body was supporting the ground. Within ten minutes, his legs lost their instinct and he couldn't help but pounced forward, directly pressing Qi Shi, who was sleeping, to the ground.

Falling to the ground, the dog barked in confusion, feeling that his paws had stepped on something soft: "Ouch...? (Why does it feel soft?)"

Look down.

"!!!"

Gouzi quickly lifted his paw that was on Qi Shi's face, and was relieved when he saw that the other party just frowned and showed no intention of waking up.

He carried him to the bedroom.

…

Perhaps because he was too tired, Qi Shi slept until the afternoon, and his head was still groggy when he woke up.

Qi Shi stood up with messy hair, rubbed his face and said confusedly: "Hmm... Why does it feel like my face has been stepped on?"

The dog under the bed shrank back and licked its fur pretending to be nonchalant.

After washing and tidying up a little, it was already three o'clock in the afternoon.
