The fourth class advancement! Becoming air!

One hour later. Qin Feng stood on the second underground floor of the Evil Spirit Academy, arriving before the Eight-Armed Thief Saint.

"Asa—Guild Master, it is an honor to see you."

Seeing Qin Feng, the Eight-Armed Thief Saint bowed slightly, his eight arms covering his chest, looking very respectful toward Qin Feng.

He couldn't help it; he was too nervous!

This human player before him, who could beat him down to half health at such an early stage… he had never heard of such an existence before!

At first, he thought an NPC had come to deal with him, but it turned out… it was actually a player?

Blue Star Civilization is truly terrifying!

However, Qin Feng clearly didn't have any feelings for this guy. He was just here to upgrade his 'Thieving Saint's Hand' skill.

After this harvest, Qin Feng had enough tradable lifespan to give himself a good boost!

"Three Hideouts sold for a total of 15,395 years of tradable lifespan."

"After deducting the share for Zhang Jinxuan, my own income is 14,625.25 years!"

The share that the Soul Painter girl received alone was a full 769.75 years. It is evident what a huge sum of money this is.

Besides that, Gui Ling had already taken that pile of useless equipment and traded it with the Yunshan Inn guild for 1,500 years. This girl donated the tradable lifespan directly to the guild after the trade. It was equivalent to Qin Feng being able to use it at will.

Furthermore, Qin Feng packaged a batch of equipment below level 18 and sold it to Wan Ye Wei Yu. These pieces of equipment included Emerald-grade, Platinum-grade, and quite a few Gold and Silver-grade items. All together, they sold for over 12,000 years of tradable lifespan.

The Magic City Ruins could not even digest this batch of equipment. It took a coalition with several other urban districts to acquire so much, and they would likely choose to sell it to the Government of other cities later, earning the price difference as intermediaries… So, the Shanghai Government definitely didn't lose out. As for who lost out, that is a matter of opinion…

Ultimately. Adding all this income together, the tradable lifespan on Qin Feng reached 31,000 years!

"It is a good thing I have the Ghost Fire Bell."

"Otherwise, carrying so much tradable lifespan on me would really be a hot potato." Qin Feng remarked with emotion.

Carrying so much tradable lifespan, if he died once, over 15,000 years of tradable lifespan would be dropped! That light orb of tradable lifespan would probably be as big as half a room!

With the Ghost Fire Bell, the only thing Qin Feng needed to worry about was someone using skills like 'Curse of Blooming' to drain tradable lifespan from his corpse after death.

But in fact… with Qin Feng's current strength, as long as he didn't court death himself, it was impossible for him to die. Therefore, he basically didn't need to consider such situations.

Soon, Qin Feng's attention returned to the skill bar.

"The Thieving Saint's Hand skill requires 200 years to upgrade from level 1 to level 2."

"It requires 300 years to upgrade from level 2 to level 3, and so on…"

Qin Feng knew that this skill could not be leveled up through other means; it could only be upgraded by purchasing from the Eight-Armed Thief Saint. After all, this was the racial legacy skill of the Celestial Thief Clan. Therefore, this sum of tradable lifespan had to be spent.

For others, upgrading Thieving Saint's Hand each time would only mean stealing 10 more points of attributes. But for Qin Feng… even though the Thieving Saint's Hand skill had only evolved to 'Legendary', every level he increased could allow Qin Feng to steal 150 more points of attribute cap!

"As long as I upgrade Thieving Saint's Hand to level 20, I can steal a total of 3,000 attribute points."

"The total cost is… 20,900 years of tradable lifespan?"

"That's fine, upgrade!" Qin Feng made his decision and chose to upgrade Thieving Saint's Hand all the way to level 20!

—— [Thieving Saint's Hand [1] (Legendary): Level requirement 1 → 20… Permanently steal 1 → 3 points of random four-dimensional attributes from the target, cooldown 6 (1.28) hours. Attribute points obtained through this skill: 5/75 → 5/1500]

[Thieving Saint's Hand [2] (Legendary): … 5/75 → 5/1500]

[You have consumed 20,900 years of tradable lifespan!]

[Your NPC subordinate 'Thief Saint · William Scott' has collected 20,900 years of tradable lifespan through the skill upgrade service. Based on the 50% tax rate, you have received 10,450 years of tradable lifespan, which has been deposited into the guild Lifespan pool!]

The guild Lifespan pool is where the guild stores tradable lifespan. However, players cannot actively deposit tradable lifespan into it. Only the tradable lifespan obtained through guild taxes will enter the guild Lifespan pool, and the tradable lifespan within the pool is public to all guild members.

In normal guilds, all expenditures of tradable lifespan within the guild Lifespan pool are announced to all guild members and require a vote by all guild members.

Of course. It didn't matter for Qin Feng. He was the Guild Master and possessed the highest voting weight; the guild's tradable lifespan was his tradable lifespan!

"Thirty thousand years of tradable lifespan, spent twenty thousand, still have twenty thousand, I am truly a math genius!" Qin Feng smiled and then looked at the evolved 'Thieving Saint's Hand' skill.

"Level 10 Thieving Saint's Hand can steal 2 random attribute points each time."

"Level 20 Thieving Saint's Hand can steal 3 random attribute points."

"The speed of attribute theft is faster!"

According to Qin Feng's current cooldown speed, it would probably take him a month to stack these 3,000 attribute points. On average, he can steal at least 100 attribute points per day—the growth potential is maxed out!

"Later on, I will need 8,900 Evolution Points to evolve this skill to Mythic…"

"Let's put that off for now."

Qin Feng decided that he still needed to save up 3,000 Evolution Points first to evolve the 'Abyss Wither Curse' once more. He wanted to see if he could remove the negative effects. That way, he could continue to fish out more Abyss Curse skills from the vase.

Next, it was time to continue grinding monsters to level up!

After Gui Ling obtained the 'Assassin' Bloodline, its overall attributes skyrocketed, and it also gained 5 points of Instant Death Affix, causing its monster-killing efficiency to skyrocket.

And Qin Feng was planning to find a level 30 Epic-grade Bloodline monster, the 'Deathwing Angel', after reaching level 30 to obtain his second Bloodline.

The appearance probability of this Bloodline monster was not high, but it was very suitable for Qin Feng. However, he might not happen to encounter it… If he didn't encounter it, there were some secondary options he could use first and replace later when he encountered the Deathwing Angel.

The next day. Early in the morning, more than 600 kilometers west of the Magic City Ruins, in a poisonous swamp, Qin Feng killed a Gold-grade Magic Swamp Frog with one slash, finally accumulating enough experience.

The fourth class advancement! After accumulating experience for so long, he had finally achieved it. Qin Feng opened his attribute panel, issued the command, and proceeded with the class advancement!

—— [Your Shadow class has advanced!]

[Current: Third-tier → Fourth-tier!]

[Class attribute bonus: Strength 54 → 108, Constitution 54 → 108, Agility 144 → 288, Spirit 90 → 180!]

[Class Passive 2: +2 Stealth Level, and the final Stealth Level is doubled!]

[Class Passive 4: When you launch an attack while in Stealth, you will not exit Stealth, and 'Stealth-Breaking Attack' will still take effect. New addition: When you launch an attack while in Stealth, all attack special effects will also be invisible, and they will enjoy half of the Stealth Level!]

This time with the class advancement, besides the attribute bonuses doubling again, two passives were also enhanced.

"The final Stealth Level is doubled!" Qin Feng already had a Stealth Level of 28. Wouldn't that mean a Stealth Level of 56 now?

Although no one could see through his stealth anyway, having a higher Stealth Level… would allow him to obtain higher Stealth-Breaking Attack! This one special effect alone caused Qin Feng's Stealth-Breaking Attack to directly double, skyrocketing from over 10,000 to over 20,000!

And what was most shudder-inducing was the enhancement of 'Class Passive 4'.

"Attacking while in Stealth, and all attack special effects also become invisible?!" This meant… Qin Feng's Shadow Blade, Instant Shadow Slash, blade light, Poison Trap… and so on, all attacks became completely invisible and intangible!

In a sense… Qin Feng in the Stealth state was almost like air!
