330: Chapter 330 I think I can't hold back anymore

"When you were running just now..." Lin Fan paused for a beat, "all four of your limbs were touching the ground."

Zhou Kai was stunned.

He lowered his head to look at his hands, his palms covered in sand.

Recalling his movements from just now, he had indeed been running on all fours.

Furthermore, that posture was extremely natural, as if it didn't need any adjustment period, and his body's instincts had just done it that way.

Zhou Kai recalled that when his body moved, his mind only thought of catching up to it, and until just now, he hadn't noticed that his posture was wrong.

"N—No... Could this be a sequela from that wolf?" Zhou Kai scratched the back of his head.

"High probability it is." Xu Zhixia nodded from behind.

The air fell silent for a few seconds.

"Whatever, let's go again!" Zhou Kai, currently immersed in the joy of obtaining supernatural power enhancements, directly skipped over that awkward fact, "Brother Fan, put some effort into it. The last one lacked too much challenge."

"Alright." Lin Fan reached out again and took back the thing Zhou Kai had picked up and brought back.

Zhou Kai's expression changed, "Brother Fan."

"Hmm?"

"Can we switch to a different one?"

"What's wrong?"

Zhou Kai pointed at that bone, then pointed at himself, and then made a running posture on all fours.

"You throw a bone out, and I chase after it on four legs to fetch it back. Isn't this fucking..."

He didn't say that word out loud, but everyone present filled it in.

A dog.

Standard fetch.

The three women couldn't hold it in, their expressions varying. Yang Ningcong was five meters away, wanting to laugh at him but not daring to.

Lin Fan glanced at the bone in his hand, then casually tossed it aside.

"Hehe, sorry, I just picked it up casually and didn't pay attention to what it was."

The expression on his face didn't change much, but Zhou Kai always felt that the arc of this person's mouth corners was a bit off.

"You did that on purpose."

"No, I didn't."

"You definitely did it on purpose. You're taking revenge for last night in the Karst Cave."

"Really didn't, it's a coincidence."

Zhou Kai stared at Lin Fan's face for three seconds and decided to drop the matter.

Lin Fan bent down again, this time picking up a fist-sized stone from the ground.

"Use this one this time."

Zhou Kai nodded and reset his stance, but this time he intentionally stood straight, deciding to run on two legs.

He was human, and he wanted to run the human way.

"Are you ready?" Lin Fan asked.

"Bring it on!"

Lin Fan flicked his wrist. This time, he held nothing back.

All the arm strength of Triple Enhancement was concentrated on his wrists and fingers, so fast that the naked eye could only capture a blurry line.

Zhou Kai's legs pushed off the ground, his entire body shooting out like a projectile.

His running speed on two legs was still far superior to ordinary people, but compared to his state on all fours just now, it was slower by more than a notch.

And the flying speed of that stone was more than six or seven times Lin Fan's normal throw.

Zhou Kai hadn't run far before that stone had already landed in the sand.

He stopped, panting. He couldn't catch up; the gap was too far.

Zhou Kai turned around, hands on his hips, his mouth missing three teeth splitting open again.

"Brother Fan, are you treating me like a missile interception system? Which normal person throws things at this speed?"

Lin Fan stood in place and watched Zhou Kai for a few seconds.

He had a clear idea in mind.

Zhou Kai's current physical fitness in human form was roughly about twice that of an ordinary person.

It was even faster when running on all fours, close to twice.

But compared to the full output of Lin Fan's Triple Enhancement, there was still a clear gap.

It was enough.

At least when facing ordinary mutants, Zhou Kai already possessed the ability to fight independently.

"Let's go back." Lin Fan turned and walked toward the Karst Cave direction.

Zhou Kai jogged a couple of steps to catch up, leaned close to Lin Fan, and lowered his voice.

"Brother Fan, seriously, just now when I was running on four legs..."

"What is it?" Lin Fan looked at him.

"Uh... I don't know why, but running in that posture feels fucking great."

Lin Fan's footsteps paused for a moment.

Running on four legs feels great? He looked at Zhou Kai.

Inheriting speed and strength was a good thing.

But what about habits?

That running posture on all fours just now didn't look like deliberate imitation, but rather like an instinctive reaction of the body.

Wait.

An image flashed through Lin Fan's mind.

That bone he had casually picked up just now—Zhou Kai's reaction upon seeing it was that it was embarrassing.

This meant... subconsciously, Zhou Kai's body did not generate an instinctive resistance to the action of "chasing bones". What he resisted was the cognitive label of "acting like a dog".

But wolves don't eat bones.

Dogs eat bones, dogs fetch bones, dogs wag their tails.

Wolves are pack predators that tear and swallow meat; bones hold no attraction for them.

So what on earth did Zhou Kai inherit?

A pure wolf? Or an artificially modified hybrid mixed with other canine genes?

Or more simply, the thing inside that tube wasn't pure wolf genes to begin with.

Lin Fan pushed this thought down.

Thinking about this now was useless; there was too little information to analyze any results.

The one thing certain was that before losing his sanity, Zhou Kai was indeed a helper.

His speed approached half of his, his strength was at least more than twice that of an ordinary person, plus the resilience brought by that modified body—all of these could be considered supernatural powers.

"Brother Fan?" Zhou Kai leaned over, "Why are you just standing there? What are you thinking about?"

"It's nothing." Lin Fan withdrew his gaze, "Let's go back. Don't do strenuous exercise today; the surface of your wound has grown back, but the inside hasn't healed yet."

"I know, I know." Zhou Kai rubbed his hands with a look of unfulfilled desire, "Then can we come out and run tomorrow?"

"We'll see."

Everyone returned to the Karst Cave one after another.

Daytime passed very quickly.

Zhou Kai's energy was ridiculously abundant. The itchiness of the wound hadn't subsided, but other than that there was no discomfort.

Yang Ningcong maintained a safe distance of at least three meters from Zhou Kai all day.

Whenever Zhou Kai walked east, he shifted west.

When Zhou Kai went back into the cave to sit, he squatted at the cave entrance.

Zhou Kai noticed it, but couldn't be bothered to deal with him.

Time ticked away.

The afternoon sunlight retreated from the cave entrance, the sea breeze turned cold, and the temperature dropped.

Song Ya added firewood twice, and the bonfire burned fiercely, roasting the entire Karst Cave until it was warm and cozy.

Night had completely fallen.

The wind outside the Karst Cave began to howl, lashing against the rock walls in waves.

Lin Fan was just about to arrange for Yang Ningcong to keep watch when his peripheral vision caught sight of Zhou Kai first.

Zhou Kai's shoulders were shaking, his entire upper body was shivering, his hands were resting on his knees, and his fingertips were twitching minutely.

"Kaizi." Lin Fan looked at him, "What's wrong with you?"

Zhou Kai raised his head, his complexion somewhat pale.

"I... I'm fine, Brother Fan." He rubbed his arms, trying to suppress that wave of trembling, "I just feel..."

He didn't find the right word.

This wasn't cold, nor was it pain; it was a restlessness surging up from deep within his internal organs.

The blood in his blood vessels was flowing faster, his body temperature was shooting up, his bone joints were itching, and his muscles were uncontrollably tensing and relaxing.

That strength felt on the beach during the day was churning within his body right now, as if something wanted to crawl out from beneath his skin.

"Brother Fan, I'm just a bit... restless." Zhou Kai tugged at his collar, a layer of sweat breaking out on his forehead.

Yang Ningcong's buttocks had already left the ground. He was squatting, his two feet ready to leap backward at any moment.

"Is he... about to change?"

As soon as these words came out, no one else spoke inside the cave. Song Ya stood up, shielding Su Qingxue as she stepped back two paces.

Lin Fan's dagger was already in his hand, but he didn't make an offensive stance.

"Zhixia, come take a look."

Xu Zhixia had just taken a step forward when Zhou Kai suddenly raised his hand.

"Don't!"

This shout was hurried and short. Xu Zhixia stood in place. Zhou Kai's face was covered in sweat, and his cheeks were flushed with an abnormal flush.

His breathing frequency was accelerating, and the amplitude of his chest heaving was getting larger and larger.

"Dr. Xu... don't come over." Zhou Kai's teeth were chattering, and the words were squeezed out word by word from between his teeth, "I'm afraid... I won't be able to control it... and hurt you."

Lin Fan glanced over. His pupils were contracting, and the color of his irises was changing.

"All of you back up." Lin Fan gave a low shout and stood directly in front of Zhou Kai.

"Brother Fan..." Zhou Kai's voice began to distort, a deep tremor mixing into his human timbre, "I... I don't seem to be able to suppress it anymore..."
