In the early morning, Tokyo International Airport, a crisp electronic announcement resounded!

"Attention all passengers, the K8134 flight from Tokyo to China's Yanjing will depart in 15 minutes. Please prepare to board!"

After this electronic sound emerged, the boarding gate had opened, and passengers were slowly boarding the plane with their luggage!

Among this crowd, there was a handsome young man whose eyes gleamed with intense killing intent as he glanced at the word "Yanjing" on the electronic screen, a cold curve forming on his lips:

"Madman, you dare to harm my sister Meiko, I will kill you in the cruelest way possible!"

After saying this, the handsome youth slowly entered the boarding gate with the crowd!

In the waiting hall, Sakai Mieko, wearing a hat, had a veil concealing her scarred face, but her beautiful eyes stared at the disappearing figure:

"Ye Feng, Ota Sato is the most formidable rising star of Japan, the most famous karate prodigy, and a gift from me to you..."

With a cold smile, Sakai Mieko covered her face with the hat and slowly vanished into the crowd!

...

In Siberia, Russia, there stood a solemn and majestic castle!

This castle was akin to a fortress, extremely astonishing, and at this moment, under the veil of night, it resembled a lurking ancient fierce beast, exuding a heart-palpitating aura!

Buzz buzz...

At this moment, a military vehicle swiftly rushed out from within the castle, speeding rapidly forward!

In the military vehicle, sat a blonde-haired, blue-eyed girl!

Her pretty face was extremely beautiful, like the Statue of Liberty, making hearts race!

The girl brushed her hair aside, her cherry-red lips slightly drawing up into a tempting curve:

"That guy is finally returning to Yanjing! My chance has arrived…"

Yuliy, a genius girl from Russia's Mixed Martial Arts Alliance, was heading towards... China!

...

At this moment, Ye Feng was unaware that the mysterious Vera, one of the Twins, karate prodigy Ota Sato, and genius girl Yuliy were all heading to China!

Moreover, all of them were coming for him!

Right now, Ye Feng was standing in a courtyard on the outskirts of Jiangnan City!

Behind Ye Feng were the core members of Blood-colored Maple Leaf!

"Ye Feng, this time our research is highly successful; Bai Ling and I have successfully developed three types of genetic potion: ABC!"

In front of Ye Feng stood an old man and a gorgeous woman, none other than Old Tong and Bai Ling!

Since Ye Feng went to Malaysia, the two had been in the suburban laboratory researching Energy Source Stones, and now, they've finally made progress!

Old Tong was holding a test tube containing pale red potion, speaking excitedly to Ye Feng:

"Ye Feng, I must say, the hand washing water you left behind was incredibly profound and played a massive role in this research!"

"Our C-level genetic potion is intended for ordinary people; it won't enhance their strength and speed but can improve cellular vitality, truly rejuvenating and extending life!"

After saying this, Old Tong put down the C-level genetic potion and took another test tube containing pink liquid, continuing:

"This is our B-level genetic potion, aimed at people with better physical fitness, capable of greatly enhancing their strength and speed, allowing them to quickly become second-level experts, and most importantly, with no side effects!"

Second-level experts are almost on par with national second-level sports masters!

The effect of the B-level genetic potion in improving physical fitness made Ye Feng's face overflow with joy and then asked:

"What about the A-level genetic potion?"

"The A-level genetic potion is only suitable for second-level experts, allowing their physical fitness to swiftly elevate to first-level expert standards!"

Old Tong was ecstatic; with these three types of genetic potion, it almost meant that an ordinary person with decent physical fitness could be quickly cultivated into a first-level expert.

Moreover, it could be mass-produced, and the value is self-evident!

Ye Feng nodded; Old Tong and Bai Ling truly did not let him down. With these three genetic potions, he could completely cultivate the ordinary members of Blood-colored Maple Leaf into powerful figures like the Blood Elite!

However, it's slightly regrettable to him that these three potions seem to have little effect on people beyond first-level experts!

"Old Tong, is there any genetic potion aimed at first-level experts and super first-class experts?"

Upon hearing this, Old Tong couldn't help but display a wry smile, while Bai Ling gave Ye Feng a deep look before saying:

"Ye Feng, the success rate for that kind of potion is too low! Previously, we conducted hundreds of experiments, and only succeeded once, that being the potion suitable for super first-class experts, which Luo Qi consumed!"

Upon hearing his name mentioned, Tanglong Luo Qi walked straight to Ye Feng, respectfully saying:

"Chief, the potion developed by Old Tong and Bai Ling is indeed extremely effective; after consuming it, my physical fitness greatly increased, and now I've nearly stepped into the S-class! Although unfortunately, I still couldn't defeat Blood Butcher..."

Previously, when Blood Butcher clashed with Blood-colored Maple Leaf, Demon and others suffered nearly complete defeat, but Tanglong Luo Qi consumed the genetic potion, and only then resisted Blood Butcher's assault, preventing heavy losses for Blood-colored Maple Leaf!

Upon hearing that an effective genetic potion for super first-class experts could be developed, Ye Feng immediately became interested, urgently asking:

"Although it's a bit troublesome, the value of such genetic potion is greater! Old Tong, I hope you and Bai Ling can quickly develop a batch of genetic potion suited for first-level and super first-class experts! The sooner, the better, but you must ensure no side effects!"

Ye Feng increasingly felt that Blood-colored Maple Leaf's strength was too weak; after all, aside from himself, there wasn't even an S-class expert to oversee, and if another expert like Blood Butcher attacked, it would be hard to defend!

Jiangnan is Ye Feng's rear base, and absolutely cannot face any mishap!

At this moment, Old Tong and Bai Ling were both amused by Ye Feng's words!

"Ye Feng, the Energy Source Stone you left us long ago ran out! Otherwise, we could have developed a higher-level genetic potion!" Bai Ling said to Ye Feng, feeling speechless.

"Ran out?"

Ye Feng was taken aback, then smiled slightly:

"I see, but it's okay, I still have some here!"

As he said this, Ye Feng took out a small bag from his pocket, and when the contents spilled out, everyone present couldn't help but gasp!

"So...so many..."

Seeing over a dozen small Energy Source Stones on the table, the breaths of Old Tong and Bai Ling became somewhat rapid!

It's known that China deployed the Shadow Group to search for Energy Source Stones, but the results were scarce, and now Ye Feng went out once, and harvested this many!
