Chapter 164 - 164 129 Upgrade Again (4000)_2

Chapter 164: 129 Upgrade Again (4000)_2 Chapter 164: 129 Upgrade Again (4000)_2 Casio mused, as the carriage wheels rattled on.

The carriage stopped at a station not far from Black Rain Villa.

Casio climbed down from the carriage, making no attempt to open an umbrella. Instead, he allowed the rain to wash over the blood stains on his cloak.

Next to the station, an Eerie Night Guest waiting for the carriage looked at Casio in surprise, then began to shake a bell with great force.

The black carriage, originally stationary, responded to the summoning bell, slowly started to move, and refocused its direction.

The Eerie Night Guest brushed past Casio to board the carriage, immediately followed by a high-pitched scream of terror.

“Aaahhh!”

The shrill sound pierced the sky.

With a nonchalant expression, Casio walked along a woodland path, stealing a glance at the upper right corner. There was good news and bad news. He was correct in his supposition, as evident by the increment in time progress bar—the good news. The bad news was that the time progress bar had only increased by a day, which did not reflect the effort Casio had put in.

So, he still had to hunt the decayed knight…

Fortunately, Casio had been prepared. He hadn’t yet completed his recurring three-month tasks, preferring to wait and evaluate the final situation to decide whether or not to defy Black Rain Villa.

It seemed now that Casio would have to be pursued at least once.

The decayed knights, according to Casio’s twilight memories, were quite powerful, divided into several different types. Yet, without exception, they all possessed formidable combat skills, similar to masters immersed in various fighting skills for centuries!

Once they engage in combat, an Eerie Night Guest is doomed!

Without a doubt, the decayed knights are powerful. If Casio wants to hunt them instead, he probably has to plan thoroughly.

Muscles aren’t omnipotent…

Half an hour later, at the Crossbow stronghold of Black Rain Villa.

A tall figure stood in the rain, knocking on the door.

“knock, knock, knock…”

“Coming… coming!”

A clear, pleasant female voice came from inside.

“Hello, ah…”

Standing before Casio was a cute and pure girl in her twenties, fair-skinned with short, cute hair. Her face exuded an innocent feel, like a novice.

At this moment, her face bore a frightened expression.

To her, Casio was clearly not one of the thin members of the Crossbow faction. Instead, the burly man outside wore a black cloak, emanating an intimidating presence and reek of blood. His dark hat concealed a pair of cold eyes.

The girl involuntarily swallowed, retreating two steps.

“You… hello. May I help you? This is our Crossbow stronghold… we typically don’t allow outsiders in…”

She balled her hand into a fist, summoning the courage to speak to Casio.

“I’m not an outsider…” The deep voice resonated.

Casio’s robust figure stepped in. His strong arm swung in front of the girl, revealing the Crossbow logo.

“Where’s Black Blade? I left my room key with him.”

“I’m now in charge of Mr. Black Blade’s duties, and the key is with me.” The girl let out a sigh of relief when she saw the logo in Casio’s hand. Initially, she thought Casio was from another faction trying to pick a fight. She hadn’t expected him to be a member of the Crossbow faction.

Half a minute later.

Casio took the key and started walking towards his room.

At the door, the girl watched the silhouette moving down the hall— his broad back like a wall—murmuring to herself, “When did our Crossbow faction get such a big guy?”

She furrowed her brows as she looked down and her pupils contracted.

On the ground were wet footprints stained with blood.

As per usual.

First, Casio went back to his room to take a bath, then he had a meal at the Crossbow faction’s convenient cafeteria. During this time, many eyes were cast towards him. There were expressions of fear, amazement, disgust, and even worship on their faces. It seemed that a lot of rumors about Casio had begun to circulate after the group mission five days ago.

After lunch, Mr. Black Blade came to find him.

And an extra task was given to Casio, along with a task certificate. This was his share in a team mission based on his contribution to the fight. It was about 3.5 Dark Source.

Not bad, definitely stronger than a typical shield task.

With the task Casio took on earlier, once more he miraculously gathered energy of more than fifteen Dark Sources. It was time to buff himself once again before hunting down the Decayed Knight.

An hour later, on a street of gray bricks.

Casio headed towards the Baptism Church.

Back to the same old place, inside a dark secret room.

Tasks and objects were exchanged here.

He received a total of sixteen Dark Sources.

After a drizzling of cold black rain.

Casio suddenly gained eight Secret Soul powers.

On the secret room’s floor, he sat crossed legged, not choosing to start using it. Instead, he raised his head to glance at the upper right corner.

‘Wind Elephant Fist: Elephant Herd 68.0% (total three levels)’

‘Elephant Soul Secret Art: Insect Bite 46.7% (total three levels)’

With six months of crazy slaughter, Casio restored his strength and even improved both. His physical realm improved by 3.5%, this was the upgrade he made the last time he experimented the effects of the Secret Soul power.

Because of the conclusion drawn by the Eerie Night Guests.

If one exceeds the limit of self-improvement in strength at Black Rain Villa one time, it is likely for the Markers to lose control. They will be corroded by this power, damaging their bodies, and in severe cases, their bodies may explode and die.

Casio tested this pheneomenon.

Then he found out, the Eerie Night Guests were right. If he improves his strength too much at once and it exceeds his ability to control, it is likely to have unknown consequences on his body.

But, Casio’s Wind Elephant Fist realm is higher than the Elephant Soul Secret Art. In theory, his precise control of strength exceeds his physical realm. It implies that Casio can enhance the Elephant Soul Secret Art to Insect Bite-up to 68% without being hurt.

Therefore, he made an attempt last time when he upgraded.

He increased his physique by 3.5% at once in the chapter of Insect Bite.

The experiment concluded that his guess was correct, but with slight deviations. Casio indeed can enhance Elephant Soul Secret Art to Insect Bite Chapter 68%, samely the realm of the third blood acceleration. Nevertheless, the body still needs a smooth adaptation process.

According to the guess, he needs to rest between one month and two months every time he upgrades Insect Bite Chapter 5%. After all, in the presence of Casio’s strong physique, he can even arm wrestle with a Giant Ape.

His 5% is quite scary for ordinary people.

According to calculation.

It would take Casio approximately four to eight months to upgrade his physique to the third realm of blood acceleration.

It’s neither long nor short, it’s acceptable.

After all, if you practice the secret martial art step by step, it takes a decade to upgrade from the second blood acceleration to the third blood acceleration unless you’re tremendously talented.

Putting down his thoughts, Casio moved into the Secret Art’s posture.

Suddenly, a warm current spread from the core to the whole body.

In the effect of the Secret Soul’s power, hard muscle and strong bones in his body were rapidly changing. The muscles became more dense and firm, forming a better force delivery shape. The bones became heavier and wider, gleaming white like some kind of porcelain.

The change that required years was completed in an instant!

Casio opened his eyes and squeezed his palm. He could feel a surging power becoming stronger and stronger in his body.

‘Elephant Soul Secret Art: Insect Bite 46.7% → Insect Bite 51.7%’

The day when the Insect Bite Chapter was fully accomplished is getting closer.

After feeling the Secret Soul’s power in his body.

There is still about four and half units left.

Just now the enhancement used up three and half units, Casio couldn’t help but click his tongue. Indeed, it becomes harder later on. Previously, the Spike Chapter could increase the progress bar by a dozen or so percent with one unit of Secret Soul power, and now the conversion rate between the two is about 1 to 1%.

Remaining: 4.5 Secret Soul Power

Casio couldn’t help but cast his gaze on a technique of hard qigong.

‘Stone Armor Skill’!
