Lin Feng waited until the black-robed leader had stopped breathing before standing up.
He dug a pit and buried the bodies of all the ordinary people.
As for the black-robed men's bodies, Lin Feng had no interest in collecting them.
Although Lin Feng loathed the black-robed men, he still would not pass up looting their corpses.
To his disappointment, however, there was nothing valuable in the black-robed leader's storage ring.
Aside from a pile of crystal cores, there were only books.
The books recorded methods of genetic modification.
Lin Feng had absolutely no interest in genetic modification and burned the books outright.
The black-robed men had provided Lin Feng with a large number of Energy Points, enough for another round of upgrades.
Lin Feng had already upgraded the Bull Demon Body-Tempering Art to level six. Upgrading it again would cost 6,000 Energy Points a time.
The black-robed men had provided Lin Feng with over 50,000 Energy Points, enough for him to upgrade.
Upgrade the Bull Demon Body-Forging Art.
Lin Feng's strength began growing again.
Level seven, level eight, level nine.
The Bull Demon Body-Forging Art reached perfection.
"Congratulations to the host on obtaining the trait: physical body enhancement."
A system notification sounded, and a powerful force suddenly appeared within Lin Feng, constantly increasing his strength.
Feeling his strength continually growing, Lin Feng was overjoyed.
He had never expected upgrading an art to perfection to bring such a benefit.
His foundation, which had been far short of what he needed to advance, was steadily strengthening.
Lin Feng had a feeling that his foundation would fill up before long.
With nearly 20,000 Energy Points remaining, Lin Feng continued upgrading without hesitation.
The only art Lin Feng could upgrade now was the Mad Demon Staff Technique.
Upgrade, upgrade.
The Mad Demon Staff Technique reached level five, level six, level seven, then perfection.
"Congratulations to the host on obtaining the trait: arm strength enhancement."
A strange force appeared once again, strengthening Lin Feng's arms.
Lin Feng thrust out his hand and threw a punch.
Bang! As his punch shot out, the air compressed, and a large hole appeared out of nowhere in the wall over a meter away.
His foundation, already close to perfection, reached perfection completely. Fortunately, Lin Feng still had over 2,000 Energy Points left, just enough to raise his level.
Break through to the Second Layer of the Qi Sea Realm.
The barrier of his Qi Sea shattered outright. Primordial Power continuously poured into his Qi Sea, and it began expanding again.
An hour later, Lin Feng's breakthrough ended, and his Qi Sea had grown several times larger again.
The power surging through his body felt wonderful, and Lin Feng opened the system panel.
Name: Lin Feng Level: Second Layer of the Qi Sea Realm (0/3000) Energy Points: 410 Skills: none Divine ability: Black Iron Battle Body
There were no longer any skills in the skill section, but the martial techniques he had upgraded to perfection had already become instinctive to Lin Feng, and he would never forget them again.

Looking at the empty skill section, Lin Feng planned to find a few more arts to practice after returning.
Otherwise, his upgrading speed would be slowed down.
With his upgrades finished, Lin Feng wanted to test just how far he could go when he unleashed his full power.
First, he activated the Black Iron Battle Body.
Just as Lin Feng finished transforming, an unexpected change suddenly occurred.
"The host's physical strength has been detected as sufficient. Upgrading Black Iron Battle Body."
Hearing this, Lin Feng was overjoyed.
For Lin Feng, the Black Iron Battle Body was his strongest means of increasing his combat strength.
Now that the Black Iron Battle Body was actually upgrading and becoming even stronger, how could Lin Feng not be happy?
Bronze-colored streaks kept appearing across his previously pitch-black skin, growing more and more numerous.
The surface of Lin Feng's body continuously broke down, then repaired itself.
Before long, Lin Feng was drenched in blood.
Fortunately, Lin Feng could not feel pain. Otherwise, an ordinary person truly could not have endured this kind of agony.
Half an hour later, all his pitch-black skin had turned bronze.
"Black Iron Battle Body successfully upgraded to Bronze Battle Body."
