More than ten hours later, the hatch of the cultivation room where Chen Feng was located was finally opened.

At this moment, Chen Feng collapsed on the floor of the training room. Several hours of strenuous effort had made his eyelids very heavy, and his throat felt so dry that it felt like there were blades stirring inside. He wished he could just collapse and fall asleep.

At this moment, Chen Feng had lost all his strength and spiritual energy, and even the black demon slayer patterns on his body seemed to have dimmed considerably.

Chen Feng managed to stand up again with difficulty.

Then, using the last of his strength, he staggered out of the training room, grabbed a bottle of mineral water containing nutrient solution, and poured it directly over his head.

Bottle after bottle of nutrient solution was poured onto Chen Feng's body. However, most of these expensive life-saving liquids were absorbed the moment they touched his skin, with only a small amount of water flowing down his ankles to the ground.

Finally, after the last drop of nutrient solution was dripped, Chen Feng, as if he had been roasted in purgatory, regained his spirit and strength.

Chen Feng then let out a long breath.

According to the tutorial, Chen Feng could only attempt to reach the second level of "Soldier Body Tempering Technique" at a time. However, in order to make the most of the training resources, Chen Feng decided to persevere and try to reach the third level of "Soldier Body Tempering Technique".

So, in endless torment and pain, Chen Feng endured another two hours.

With gritted teeth and perseverance, Chen Feng finally succeeded in activating the Warrior Body Tempering Technique to level 3!

He also learned the first passive skill of the Soldier Body Forging Technique - Azure Dragon Armor.

[Azure Dragon Armor: A bio-energy armor that assists the host in absorbing energy and physical attack energy, converting it into replenishment for bodily functions. The Azure Dragon Armor is a passive attribute armor and does not require the cultivator to actively trigger it.]

After putting his clothes back on, Chen Feng left the Tower of Babel training room.

Just as Chen Feng turned the corner of the corridor leading to the guard headquarters, he ran into three guards. One of them was none other than the blond-haired man rumored to be Jian Mei's current boyfriend.

His uniform was a modified guard uniform—the shoulder straps were replaced with chrome spikes, the hem was cut into an asymmetrical swallowtail shape, two magnetic storm pistols were strapped to his waist, and some combat aids appeared to have been implanted in the iris of his left eye.

Both their clothing and appearance give off an impression that they are not to be trifled with or offended.

When Huang Mao looked at Chen Feng walking towards him, a hint of doubt appeared in his eyes.

"He's pretty handsome!" exclaimed the female guard next to the blond-haired man.

"It seems our friend Chen Feng is quite a diligent young man, having been cultivating in the Tower of Babel since yesterday," one of the older guards joked.

However, the blond-haired man at the front of the group sneered and said sarcastically, "How could someone who loves to fawn over others not be hardworking?!"

Upon hearing this, Chen Feng turned his gaze back to Huang Mao and opened Huang Mao's potential data with a thought.

Upon seeing the system's final comment, Chen Feng merely sneered and shifted his attention back to the blond-haired man.

Even without the combat power bonus from luck, Chen Feng is fully capable of overcoming the difference in rank and defeating the blond-haired guy in front of him, thanks to his rich combat experience and numerous combat skills from his previous life!

There's absolutely no need to offend him right now.

Seeing that Chen Feng ignored his mockery, the blond-haired man narrowed his eyes, turned around and stared at Chen Feng's departing figure, his eyes blazing with murderous fire.

If you don't look closely, you might not even be able to see the faint glimmers of light in his eyes.

However, the shattered light was not as clear and sharp as Wei Yang's pupil technique; instead, it was a harsh, cold light.

Chen Feng seemed to sense something, but he remained calm and continued on his way. He went straight in at the next corner and silently walked towards the staircase not far away.

"What's wrong with you, Captain Huang?" The older guard member looked at Chen Feng, who was leaving, with a puzzled expression and asked.

The blond-haired man narrowed his eyes, but said coldly.

"That guy has something going on."

"How so?" the female guard asked with a smile.

"Ha, you wouldn't understand even if I told you, and you certainly wouldn't believe me..."

The blond-haired man glared at the two men before striding towards the guard headquarters, muttering to himself, "This guy is definitely no good..."
