"Move aside, hurry up and take me to see what you and Cold Face are up to!" Liu Mengqi impatiently cursed.

But Yun Hao was very happy. Why? Liu Mengqi hadn't refused, which meant he could go ahead. Yes, that's how Yun Hao thought about it. As for whether Liu Mengqi thought the same, it didn't matter!

"Come quick, look at this tiger. Compared to when Tank bought it, is there anything different about it?" Cold Face, who rarely showed emotions, spoke excitedly to Yun Hao when he saw Yun Hao and Liu Mengqi come down.

"What's different? Did you neuter it or something? It looks exactly the same as when I bought it!" Tank had already come down, and asked in confusion after hearing Cold Face's words.

"That's why you'll never amount to anything, you ignorant fool!" Cold Face dismissed Tank scornfully.

"Damn you, poker face!" Tank replied speechlessly, unable to counter Cold Face's sarcasm with anything else!

Yun Hao was long used to Tank getting roasted by Cold Face. Apart from Liu Mengqi, had Cold Face ever shown a good face to anyone? So Yun Hao approached the tiger, which was locked in a large iron cage.

"Roar!"

The tiger, King of Beasts, even when caught and sold on the black market, still maintained its dignity. Already provoked by Cold Face earlier and injected with something, it now roared furiously upon seeing another person.

"This tiger's aura is incredibly strong," Yun Hao frowned, turning to Cold Face.

"Indeed, this tiger's strength is now five times greater than when Tank first bought it," Cold Face nodded, acknowledging Yun Hao's observation.

"What happened? Did you give it some medicine you concocted?" Hearing their conversation, Tank hurriedly asked.

But Yun Hao ignored Tank's question and said to Cold Face, "How much did you use?"

"A tenth of a drop, just a small part from here! It was diluted from one drop," Cold Face raised a small 100ml bottle in his hand.

"Any side effects?"

"None!"

"You're sure? That's practically defying the heavens!"

"Of course. But the effect only lasts for half an hour. After that, it fades! And it can only be used once every 24 hours, otherwise the effect will be weakened, and it'd be wasted!"

"Holy crap, I'm going insane!"

Yun Hao held his head in joy, and even Cold Face displayed a rare smile. This was definitely a must-have for traveling and killing, especially at such a crucial moment. If Yun Hao used it, it would give him added confidence!

One drop was enough for Yun Hao to use it ten times, in just a small bottle!

Moreover, Cold Face had even better news to share with Yun Hao.

"Damn, what the heck are you guys talking about? Can you be clearer?" Tank couldn't hold back any longer, as the two were speaking gibberish!

"Stay aside, I'm not finished speaking!" Cold Face waved his hand and continued speaking to Yun Hao, "Plus, this thing should be effective for my illness too!"

"Can your body handle it?" Yun Hao asked with concern.

"I need to study it further. I'll try neutralizing it with a few medicinal ingredients, it should be better. I'll use the next couple of days to create some pills for you. It'll be better than injecting at critical times!" With that, Cold Face stopped paying attention to everyone, waving them away.

Even Liu Mengqi wouldn't interfere with Cold Face in this state. In the Netherworld Squad, only Cold Face dared to treat Liu Mengqi like this!

So Yun Hao led the two out, but as soon as they exited the basement, Liu Mengqi and Tank pinned him onto the sofa, obviously wanting to know what was going on.

"Well, it's like this..." Yun Hao helplessly explained, mentioning how he found the Mysterious Liquid in the Blood Wolf treasury and handed it to Cold Face for research.

After Yun Hao finished speaking, both Liu Mengqi and Tank were stunned. Damn, this was revolutionary, and with a bit of exaggeration, it could boost you tenfold like a Super Saiyan transformation!

Imagine, you're in a life-or-death battle with the enemy, at the critical moment you take a medicine pill, damn, your power instantly increases fivefold or even tenfold, it's like leading a cheat code life, as if in a game you're a pay-to-win player while the others are free-to-play!

Half an hour is enough. For experts like them, it's sufficient to kill many people. Take Yun Hao for example, with half an hour of empowered effect, he could dare stir trouble in the Child Clan, but whether he'd come back alive was another matter!

However, neither of them noticed that Yun Hao was more concerned not about the power boost but the possibility of improving Cold Faces's condition. Others may not know, but Yun Hao knew that Cold Face, like him, had a congenital condition, only his could be cultivated, while Cold Face's could not!

So, Cold Face's combat strength was really weak, as weak as not being able to defeat even a Gold Member of Dragon Scale, but don't be fooled into thinking he's easy to deal with. You wouldn't even know how you died!

Cold Face's medical skills were astonishing, and his toxicology expertise was terrifying, capable of using poisons invisibly. Anything related to toxins, he could handle, and he's always accompanied by Death Puppet, even Yun Hao had no idea where these were hidden, but Cold Face could always summon them immediately when needed!

Nothing more was spoken throughout the night. The next morning, another guest arrived at the manor, someone who made Yun Hao want to flee upon hearing the name: Shafei!

"Dear Yun, why didn't you come find me when you arrived in Germany?" Shafei wore a leather skirt and a strap top.

"Oh, it's Shafei, I just got here, I haven't had time to find you yet!" Yun Hao casually lied, then reluctantly went forward to greet her.
