"Senior, is your main body busy right now?" Bai Fei asked in confusion.

After a brief flash, Chen Feng's physical clone regained its expression, which had been frozen in time.

"Yes, I just got back to my dorm. I can probably stay with you for another ten or so hours."

"If it's a dozen or so hours, I feel like we could have a hunt..."

What are your plans?

With Bai Fei's careful explanation, Chen Feng also gained a preliminary understanding of this body of water.

In the largest lake of this giant beast forest, besides numerous enormous beasts, there are also several beast-like servants.

That's a dragonfish.

They are agile and can reach several meters in length, with a sharp, streamlined head that resembles a long, lance.

The dragonfish has blood-red eyes and its upper and lower jaws are covered with sharp, knife-like fangs. These teeth are arranged in a serrated pattern, and once they bite their prey, there is no chance of escape.

The back of the dragonfish is also covered with a layer of hard and rough scales.

These scales are dark black, resembling a natural suit of armor.

This makes them look like crocodiles slithering through the water.

"The giant beasts in this water do not have many servants, but these swimming dragon fish will always clean up the food scraps they plunder, so we can also regard them as servants of the giant beasts in the water."

"In addition, there is another extremely ferocious carnivorous shark whose skin is covered with dense dermal scales, and the color of its back often blends in with the silt at the bottom of the lake, which makes them very quiet when they attack."

As Bai Fei explained, she drew the outlines of the two servant beasts with her hand.

"Honestly, this body of water seems more dangerous than the insect hive on land," Chen Feng sighed.

"It's alright, senior, I will definitely make sure the insect hive grows smoothly," Bai Fei said.

"It's good to have this confidence, but... wait a minute..."

Chen Feng suddenly remembered that he still had three random weapon exchange coupons. If he could exchange them for some protective gear for Bai Fei, her chances of success would increase significantly.

Chen Feng drew out a random weapon exchange coupon and pressed the exchange button.

Ding!Ding!Ding!

Ding!Ding!Ding!

(๑•̀ㅂ•́)و✧ A firework suddenly exploded in the center of Chen Feng's vision...

[Lucky Contract: The system has automatically adapted to the contractor's current scenario and will redeem a weapon suitable for "aquatic scenarios" for you.]

[Lucky Contract: Successfully redeemed "Abyss Strangler Whip (Permanent)", which can cut through water to create a vacuum channel with its opening and closing bone blade, allowing the strangler whip to advance at 3 times the speed of sound (approximately 1500 meters per second underwater). Simultaneously, when entangled in a target, the strangler whip can solidify into a barbed chain that can penetrate 5 cm thick iron armor (guaranteed not to entangle the user!)]

Chen Feng immediately produced a long, smooth-looking metal whip in his hand, which did not appear to be very long.

"Bai Fei, try out this weapon..."

"Such a short whip?"

Bai Fei accepted the "Abyss Strangulation Whip" with some skepticism and then walked to a rock.

Neither of them initially thought that this 1.6-meter-long metal whip could be of any use.

After all, the giant beasts in the Giant Beast Lake move extremely fast, often swimming dozens of meters in the blink of an eye. At that time, let alone using this to stop them, even taking out a whip might not be enough to catch up.

However, Bai Fei still lashed out with her whip towards the water not far away.

Just then, a miracle happened!

Bai Fei's consciousness surged into the whip like an electric current, causing the strangulation whip to suddenly grow to a length of 4 meters.

The dozens of bone blades at the front end vibrated wildly at a frequency of thousands of times per second!

The "Abyss Strangulation Whip" lashes the water's surface instantly...

boom----!!!!!

A transparent shockwave, three meters in diameter, exploded outwards from the center of the strangulation whip!

The once calm lake water was suddenly torn open by a vacuum rift several meters deep!

Wherever the shockwave passed, even the mud and rocks at the bottom were instantly blasted into a cloud of murky water mist!

Chen Feng and Bai Fei's eyes widened in shock, because their heightened senses allowed them to directly perceive the intensity of the strangulation whip's attack—a death whip equivalent to three times the speed of sound, capable of shredding a 20-centimeter-thick iron block in two!

rustling sound —

After the first lash, the "Abyss Strangulation Whip" immediately began to shrink back and returned to its original petite and docile form.

Just as Chen Feng was a little stunned, Bai Fei looked at him happily.

His eyes were full of gratitude.

"This will be a very useful underwater weapon. Thank you, senior, Bai Fei!!"

......

Ding!Ding!Ding!

Ding!Ding!Ding!

(๑•̀ㅂ•́)و✧ Another firework exploded suddenly in the center of Chen Feng's field of vision...

[Lucky Contract: The system has automatically adapted to the contractor's current scenario and will redeem a weapon suitable for "aquatic scenarios" for you.]

[Lucky Contract: Successfully redeemed "Whispers of Chaos (3 times)," a Perception Disruption Sound Wave Generator, capable of disrupting the perception of underwater creatures across the entire frequency range. By mimicking the cries for help, the cries of cubs, or the roars of territorial declarations of other behemoths, it induces them into chaos, causing them to fight each other or flee the water. (Guaranteed not to disrupt the user's perception)]

"This is pretty good!" Chen Feng handed the small "Whispers of Chaos" to Bai Fei.

"What's this new gadget?" Bai Fei asked with a smile as she accepted it.

"It can disrupt the senses of all underwater creatures without affecting its own sound generator, but it's a bit inconvenient to carry around..."

"It's alright, senior... I can embed such components into my aquatic armor."

"That's good..."

After exchanging for two powerful weapons, Chen Feng felt that was about enough, so he closed the system inventory.

They then walked towards the aquatic insect nest, carefully observing the countless small octopuses hunting the creatures in the lake.

Bai Fei followed Chen Feng to the aquatic insect nest and watched intently as her subordinates hunted.

"Senior..." Bai Fei said softly.

"kindness?"

"How about we go and have a go at those carnivores?"

"Those things you mentioned? How many of them do we have to kill to advance?" Chen Feng asked, somewhat puzzled.

"Of course not, I'm talking about a Xuan-rank aquatic behemoth—the Giant Dragon."

"Now? Didn't you just say that the Dragonfish and the Carnivorous Shark were quite a threat? Now you're going straight to fight the Profound Rank?" Chen Feng asked, looking puzzled.

"Because I know you must have a backup plan!" Bai Fei said playfully.

"What backup plan?"

Bai Fei raised her hand and pointed to the upper right, but a slightly embarrassed smile appeared on her lips.

Chen Feng immediately looked in the direction Bai Fei pointed.

However, what he saw was [Luck Value: 9650]

Putting aside the question of whether Bai Fei's ability to see Chen Feng's luck value is due to an upgrade of the intimacy system or something else entirely.

Chen Feng finally realized that he still couldn't resist the unreasonable demands of the obedient Bai Fei...

Chen Feng: "I knew you were only after my luck stat..."
