After a long time, when the test results from the Super Strong Muscle Analyzer came out, the entire laboratory was immediately filled with excitement!

"He... he's truly evolving! Oh my god, it's true... the density of his blood and flesh, the precision of his bones, the activity of his cells, far exceed the human range! Evolution, this is indeed evolution!!!"

Old Tong looked at the string of body data displayed on the Super Strong Muscle Analyzer, and his entire elderly face immediately broke into extreme elation!

All his life he had devoted to scientific experiments, with the greatest ambition of making achievements in this field, and now this discovery would undoubtedly be a new milestone in human history!

Humans can actually evolve, which almost means the era of full exploitation of the human body has truly arrived!

"Bai Ling, quick, since Demon Body No. 1 has already evolved, it requires a massive supplement of nutrition, immediately inject double the Energy Potion!"

Just after seeing the data on the analyzer, Old Tong hurriedly instructed Bai Ling beside him!

At this moment, Bai Ling's beautiful eyes were filled with a rich brilliance as she looked at Ye Feng, without understanding how Ye Feng was able to perceive it.

Even for her and Old Tong, they could only test the physical data of Demon Body No. 1 using the analyzer!

Nonetheless, Bai Ling did not hesitate, she flashed a charming smile at Ye Feng, nodded slightly, and then turned aside to start blending more Energy Potion!

Meanwhile, Old Tong came beside Ye Feng, his face full of excitement:

"Ye Feng, you're really something! If you hadn't stopped me, the evolution of Demon Body No. 1 would have definitely been interrupted if I had injected that Protein Liquid! At that time, this great moment in human history would have ended here!"

Old Tong was completely convinced by Ye Feng now!

Even though the other party was young and not a professional researcher, his sharp and sophisticated Eye Power was something Old Tong had never witnessed in his lifetime!

Ye Feng smiled faintly, he was able to foresee the evolution of Demon Body No. 1 because he had a similar experience!

Back then, to save Chouchou, after devouring the Energy Source Stone, his own body's reactions were almost identical to that of Demon Body No. 1.

Moreover, he could clearly sense that what was emanating from Demon Body No. 1 was not weakness but a growing powerful aura!

Previously, even for Ye Feng, not to mention Super First-class demons, even S-level masters rarely gave him a sense of crisis.

But now, the aura exuded by Demon Body No. 1 gave him a very real sense of danger!

Looking at the increasingly painful appearance of Demon Body No. 1, Ye Feng's face brimmed with intense joy:

"Ah Yi, since you are evolving, as your master, I'll give you a serendipity!"

After saying this, Ye Feng pulled a fine Needle from his pocket and then plunged it sharply into his chest!

This scene caused Old Tong's face to change drastically, and Bai Ling was even more startled!

"Ye Feng, you... what are you doing!!!"

Their faces were full of horror, as the place Ye Feng had pierced with the Needle was precisely the heart, a deadly spot.

If anyone's heart is pierced, they have no hope but death, and the two quickly stepped forward to stop him!

However, Ye Feng waved his hand:

"No need to worry, I'm fine!"

Ye Feng's brows furrowed, the intense pain in his heart made his face pale, and a little cold sweat seeped from his forehead!

However, he didn't care. At this moment, he walked to the front of Demon Body No. 1 before pulling out the Needle from his chest!

The silvery Needle shimmered with a hint of crimson, which was Ye Feng's most precious thing - Heart Blood!

Ye Feng's Heart Blood could absolutely bring the dying back to life!

And now...

Ye Feng placed the Needle above the lips of Demon Body No. 1, letting it fall directly.

Only to see the crimson blood on the Needle slowly slide off, finally condensing into a drop of Heart Blood and then instantly falling onto the lips of Demon Body No. 1!

At this moment, Demon Body No. 1, almost losing its sanity due to the abnormal state of its body, sensed the sweet and metallic taste on its lips, licked it violently, and swallowed the Heart Blood immediately!

Ye Feng's Needle repeatedly extracted Heart Blood, drop by drop swallowed entirely by Demon Body No. 1!

After allowing Demon Body No. 1 to drink down a dozen drops of Heart Blood, Ye Feng finally paused, and then fed several other demons a few drops of Heart Blood each!

After all ten demons drank the Heart Blood, Ye Feng's face became increasingly pale, and the sweat on his forehead flowed like an opened faucet!

But Ye Feng didn't care, on the contrary, the anticipation on his face grew even more intense!

In Ye Feng's expectant gaze, the aura on Demon Body No. 1 grew even more turbulent and fierce, with their physical quality rapidly soaring!

Not only Demon Body No. 1, but the other nine demons' body data also soared rapidly, a speed that astonished Old Tong and Bai Ling to death!

"Evolve! They've all evolved! God, what... what exactly is happening!"

Old Tong looked at the accelerating body data of the ten demons on the analyzer, his face filled with sheer horror!

He had experimented countless times on those criminals, but never had there been a case of human evolution, and now there were ten cases!

He knew, this was definitely inseparable from Ye Feng's Heart Blood!

Bai Ling's pretty face showed a complex expression, feeling that Ye Feng was like a mysterious treasure, and you could never predict what kind of surprise he would bring next!

"What... kind of person is he..."

The brilliance in Bai Ling's charming eyes deepened even more as she looked at Ye Feng, filled with curiosity and a certain unusual feeling!

At this moment, in the gaze of the three, the ten demons continued to evolve, their bodily data surged for a full half hour before slowly stabilizing!

And when the evolution process was entirely completed, continuous waves of overwhelming aura emanated, pressing down on Old Tong and Bai Ling until it was hard for them to even breathe!

"Too... too powerful, this... is this the new mankind?" Old Tong and Bai Ling looked at the ten demons on the experimental bed in utter shock!

And Ye Feng, with a pale face, revealed a deeply gratifying smile!

He could clearly sense that these ten demons had definitely stepped into the S-level realm, and even their physical quality was extremely powerful within the S-level!

Especially the physical quality of Demon Body No. 1, which was absolutely top-notch within the S-level, even with one foot stepping into a level beyond S!

Whoosh! Whoosh! Whoosh!

Just under the expectant gaze of Ye Feng and the others, the ten demons on the experimental bed all opened their eyes!

Their gazes were incredibly sharp, like sharp swords, making it hard for people to look directly at them!

After opening their eyes, the ten demons were initially slightly dazed, but when they sensed the boundless power in their bodies, they were overwhelmingly joyous!

The scene where Ye Feng extracted Heart Blood drop by drop appeared vividly in their minds, causing these ten individuals to tremble all over, with shock and gratitude on their faces!

Then the ten leaped off the experimental bed and knelt down on one knee in front of Ye Feng together!

The 'bang bang' sound echoed endlessly, and their expressions were extremely respectful:

"Thank you for your grace, Master!!!"

Sounds of gratitude and awe rang out!

The ten demons!

Ten S-level top masters!
