"What’s the plan? Are we going to fight it?" Li Wenqiang asked.

"Rainbow oysters, or even phantom rainbow oysters have weak offensive capabilities but extremely high defence. Breaking its shell won’t be easy." Feng Xue said.

"I would rather we didn’t destroy the shell." Shen Xu said and quickly continued.

"The shell is an excellent material for refining armour, shields, and stealth equipment. It can also be ground into powder and used to refine the bone fortifying pill." He said.

"The bone fortifying pill is a good thing." Yang Shi said, already looking forward to the pill.

"Mmh." Shen Xu nodded.

The bone fortifying pill was a higher-level type of the bone strengthening pill.

At its most basic, it could be used to treat the brittle bones disease and other bone illnesses, and for healthy cultivators, it could be used to augment the bones, enhancing body refining and martial talent.

"Xiaoxu, can you refine the bone fortifying pill?" Zhen Yuan asked and Shen Xu nodded.

"I have studied it and even simulated how to refine it. Unfortunately, we don’t have some of the required spirit grasses." The double said and sighed in helplessness.

"It doesn’t matter." Zhen Yuan said.

After all, they were level ten body refiners and weren’t in a hurry to advance their body cultivation.

"Level nine and level ten spirit grasses are everywhere in the immortal realm. The shell will still be useable when we ascend." Feng Xue said and Shen Xu nodded.

"I will shuck the oyster." He said and quickly continued.

"Maybe we will discover its secrets when I open the shell."

After that, Shen Xu rushed forward with a sword in hand.

Seeing the attacker, the phantom rainbow oyster immediately wove an illusion, intending to trap Shen Xu.

Unfortunately, the double had long been able to see through illusions and wasn’t confused by the oyster’s little trick.

In the blink of an eye, Shen Xu inserted his sword in the oyster’s notch and tried to pry it open.

However, this was easier said than done.

Even after using all his strength, Shen Xu couldn’t open the shell and he retreated with a frustrated expression.

’This defence is not a joke.’ He thought.

In the end, Shen Xu, Zhen Yuan, and Li Wenqiang worked hard for half a day before they were able to open the shell.

After opening, Shen Xu cut the muscles and sighed.

"The meat looks delicious." Yang Shi said and licked his lips.

"I will cook it later." Shen Xu said, took out a jade box and put the meat inside before collecting the box into his storage ring.

"There are two pearls and a demon core." Yin Shi observed, her eyes wide in surprise.

"An oyster typically has one pearl. Why are there two?" She asked.

"One is not an oyster pearl." Zhen Yuan said, his eyes narrowed into slits.

At the same time, he reached for one of the pearls and rubbed it between his right thumb and index finger.

"It’s a mermaid’s heart tear." Feng Xue exclaimed in a chocked voice.

Mermaids were descendants of the ancient gods and their race was one of the strongest especially in water.

As a result, mermaid related treasures, especially mermaid heart tears, were not only rare but also precious.

Unfortunately, a mermaid only shed three heart tears in their life.

From her inherited memory, Feng Xue knew that mermaids could only shed heart tears in times of extreme sorrow, extreme happiness, or extreme love.

"This tear..., what type is it?" Feng Xue asked but soon frowned.

"Ordinary mermaid tears are large pearls and the heart tears are small pearls. There is no way to differentiate the heart pearls." Yang Shi said and also frowned.

"It’s a tear of extreme love." Zhen Yuan said and Shen Xu trembled.

A breath later, he took the pearl from Zhen Yuan’s hand and rubbed it with a reverent face.

"Ayuan, keep it." He finally said and gave it to Zhen Yuan.

The three types of mermaid heart tears had different effects.

From what Shen Xu knew, the tear of extreme love could almost bring the dead back to life. As long as a person had one breath in their body, the tear of extreme love could return them to peak health.

"Okay." Zhen Yuan said, rubbing Shen Xu’s hair with a doting expression.

After putting the tear away, the surrounding water lost its abnormal density and became ordinary water.

"I will leave the demon core and pearl for Jiaojiao." Shen Xu said, looking at the others.

"It’s not like we can use them." Yang Shi said and rolled his eyes.

"How are her injuries?" Feng Xue asked and the double sighed before shaking his head.

"She is still asleep." He said and quickly continued.

"The only thing we can do for her right now is to keep her well-nourished. We will search for her tails when we ascend to the immortal realm."

"That’s the only thing." Li Wenqiang said and the others nodded in agreement.

Although they hadn’t met Hu Jiaojiao, they had heard about her and already considered her as one of their own. Because of this, they didn’t mind that they had done the work but Hu Jiaojiao had received the benefit.

After all, family was like that!

When one was in seclusion, it was only natural for the others to find useful resources for them and protect them where necessary.

After that, everyone boarded the underwater boat and left the area.

Once the boat returned to the surface, Shen Xu put it away and released their usual ship.

"The undersea is beautiful but I still prefer the surface." Feng Xue said.

"Me too." Yin Shi echoed, transformed into her bee form and excitedly flew around.

Since they didn’t have a particular place that they wanted to go, the ship continued west but the group didn’t find another treasure for eight days.

On this day, the group was sailing as usual when the sky suddenly changed.

A breath later, Shen Xu gasped, and his lips twitched in amusement.

"Unbelievable." He muttered.
