The Supreme Martial Expert of the Female CEO

With a loud rumble, the cave trembled.

"Wow, strong legs!" Xuanyuan Xia glanced at Ling Feng sideways. "I thought you'd rush in with fearless spirit!"

"I'm not that stupid!" Ling Feng rolled his eyes and said, "What if we fall into a trap set by the Sky-Swallowing Toad?"

However, what puzzled them was that even though the boulder had been kicked inside, causing such a loud noise, there was no sign of movement in the cave, as if no creatures were residing within.

Ling Feng and Xuanyuan Xia exchanged a glance and said in unison, "Go in and take a look?"

"Let's go together! So you don't chicken out!" Xuanyuan Xia chuckled.

Ling Feng shrugged and then followed Xuanyuan Xia into the cave.

The cave was extremely large, and as soon as they entered, they were hit by a nauseating smell, a mix of putrid and rancid odor that reminded Ling Feng of the smell of bananas mixed with winter dates, as if he was revisiting past memories.

Ling Feng flicked his fingers, and the power of the Origin Water emerged, dispelling the scent surrounding Ling Feng and Xuanyuan Xia.

Xuanyuan Xia looked at Ling Feng and said, "It seems this is indeed the cave of the Sky-Swallowing Toad. That stench just now carried a strong hint of the toad, but there was also a pungent toxic smell. This means the poison inside the Sky-Swallowing Toad is starting to get uncontrollable!"

The inside of the cave was very smooth, and the ground was littered with the corpses of Poisonous Clam Shells. Although they couldn't smell anything foul, Ling Feng still felt a fishy smell lingering in his nostrils.

After walking over a hundred meters and making two turns in the cave, they finally saw the chained Sky-Swallowing Toad at the end!

At that moment, the Sky-Swallowing Toad was lying on the ground unconscious, beneath it was a pile of Poisonous Clam Pearls. Its skin shimmered with iridescent colors that kept changing, giving off a bizarre feeling.

"The poison is erupting!" Xuanyuan Xia confirmed as she saw this. "Now the Sky-Swallowing Toad is in an unconscious state; even if you attack it, it wouldn't notice! But the area around its body is the most toxic; we better avoid it."

At the other side of the cave's end was a giant Stone Gate, engraved with eerie and mysterious patterns.

And surprisingly, the two chains connected to the Sky-Swallowing Toad were linked with the door knocker on the Stone Gate.

This means the Sky-Swallowing Toad is still the Guardian of this Stone Gate.

"That Crystal Skull, it lied to us!" Ling Feng said angrily. "Luckily, sister, you are perceptive, or else we would have been really fooled by the Crystal Skull!"

Xuanyuan Xia chuckled, "It didn't really lie to us; it just selectively told us the truth. What do you think is behind this Stone Gate?"

Ling Feng frowned, "Since the Crystal Skull doesn't want us to know that the Sky-Swallowing Toad is the Guardian of the Stone Gate, then it must consider the Stone Gate extremely important! I guess it might be hiding secrets of the God race. Why don't we open it?"

Xuanyuan Xia shook her head, "To open this Stone Gate, you must kill the Sky-Swallowing Toad, and we don't have the key. Touching the mechanism might trigger a self-destruct system, which is something the Atlantis Divine Race loved to do!"

Ling Feng raised his eyebrows and then tapped the mark on his hand, "Crystal Skull, get out here, or I'll blow up the Stone Gate below the deep pool!"

After several taps, the Crystal Skull wobbled out, "Ling Feng, what's up? Didn't I say I needed rest... What the hell, how did you get here!"

Upon seeing the surroundings, the Crystal Skull couldn't help but curse.

Ling Feng sneered, "Are you surprised we are here? But before we get to that, shouldn't you explain what all this is?"

Saying this, Ling Feng pointed at the Stone Gate ahead.

The Crystal Skull hesitated, then said, "Ling Feng, we should really get out of here, it's too dangerous..."

"You can choose not to speak, but I'll blow this place up now!" Ling Feng said flatly, "Do you want to see the beauty of the Stone Gate's explosion?"

The Crystal Skull sighed slightly, "Alright, you win, I'll talk, okay?"

"Should've confessed earlier, right?" Ling Feng smiled and said, "Spill, what's behind this Stone Gate?"

The Crystal Skull deflatedly said, "Behind the Stone Gate is the most core secret of our God race!"

"The most core secret?" Hearing this, even Xuanyuan Xia's curiosity was piqued. The Atlantis Continent's God race was extremely powerful back then; without them, Earth might have long been overrun.

"That's right, it's the Mechanical Core of our God race!" the Crystal Skull said in a deep voice. "Our Atlantis Divine Race had long researched the Mechanical Core. As long as there are sufficient materials, we can mass-produce machines of the God Realm, Sea of Gods Realm, and even Azure Sky Realm!"

Ling Feng and Xuanyuan Xia exchanged glances, both seeing deep shock in each other's eyes.

"How could that be!" Ling Feng couldn't help but say. "If you could mass-produce such machines, why were you defeated by different races back then?"

The Crystal Skull retorted, "Didn't you listen carefully? I said with enough materials. Do you think materials for machines comparable to Azure Sky Realm experts are ordinary materials?"

Ling Feng was a little embarrassed, actually being looked down upon by the Crystal Skull.

"Our Atlantis Divine Race had two core elements: one was the Mechanical Core!" The Crystal Skull continued, "Back then, our mechanical research institute was attacked by different races. In a hurry, we couldn't move the Mechanical Core, so we sealed it under the pool and made the poisonous Sky-Swallowing Toad the Guardian of the Stone Gate!"

"Earlier, I sensed the existence of the Sky-Swallowing Toad, but didn't tell you the truth because I wanted to see if the Sky-Swallowing Toad was still alive and if our God race's Mechanical Core still existed! But never thought... you managed to find your way here!" the Crystal Skull sighed. "Fate is truly unpredictable!"

Ling Feng slightly nodded, "What exactly is this Mechanical Core?"

The Crystal Skull looked at Ling Feng with disdain, "Hey, the Mechanical Core is naturally the most powerful existence in machinery, equivalent to a Power Furnace! Do you remember the War God Puppet in the God race tribe around the Dark Forest?"

"Of course I remember!"

"That War God Puppet was actually a Combat Puppet made with a Mechanical Core, but its core was very basic!" the Crystal Skull said proudly. "With a top-level Mechanical Core as the Power Furnace, a constructed War God Puppet would have Azure Sky Realm strength! However, creating such a War God Puppet requires way too many materials!"
