Transmigrated into a tortoise, the Empress and the Goddess became my sisters.

As the Empress's hand approached, Lin Tian felt a cool sensation being drawn in from the turtle's navel, instantly cooling his entire body.

Not only that, but the power within his body seemed to have increased several times over, making him even stronger than before.

The Empress also noticed something different about her eating and drinking, as the energy inside her body began to increase and expand, causing her tortoise body to grow larger.

"What's going on? Why am I suddenly getting this feeling of mutual cultivation?"

For her, who was a cultivator in her previous life, this feeling was not unfamiliar; she and her cheap brother could actually engage in dual cultivation.

"Great!"

"I never expected my cheap brother to have such wisdom. I thought my ordinary brother was just an ordinary tortoise!"

"That's good. From now on, we can help each other and cultivate together. That's fantastic!"

The Empress was overjoyed and continued to maintain the balance of spiritual energy within her body, constantly collecting the yang energy emanating from Lin Tian's body.

Upon hearing this thought, Lin Tian was overjoyed. Could this be the legendary Yin-Yang dual cultivation?

That’s not right!

The empress is his own sister. Wouldn't this dual cultivation of Yin and Yang violate any ethics or morality?

I watched a lot of movies and TV dramas in my past life. The plots of dual cultivation and yin-yang dual cultivation were all from movies and TV dramas, and I had also seen them in novels.

I originally thought that I needed to have that kind of contact to reach the level of Yin-Yang dual cultivation, which is the legendary union of Yin and Yang.

But that's not actually the case. Even one's own sister can exchange yin and yang energies. This does not violate ethics or morality; it is simply exchanging spiritual energy.

As for the merging of Yin and Yang, my sister and I certainly can't accomplish it, but we'll have our other halves in the future...

At that very moment, the Empress's inner voice was heard.

"Cheap brother, quickly adjust the spiritual energy in your body so that the peaceful power can adapt to your dantian. Our mutual cultivation will definitely help you to start your cultivation."

In her eyes, Lin Tian was just an ordinary tortoise.

Since we can mutually cultivate, we should naturally improve the adaptability of our dantian to facilitate future cultivation.

I didn't know before, but now I understand that all kinds of creatures are cultivating in this secluded place.

However, since I was reborn and cultivated, I have an advantage over other creatures.

As for his cheap older brother, he's just an ordinary turtle and can't be compared to other creatures, so he needs to teach him even more carefully.

Once my brother-in-law has improved, he can return to the Nine Netherworld with me. At that time, with the two of us working together, what worries could we possibly have about not succeeding or our enemies not dying?

“Brother, mutual cultivation can improve your cultivation level. I am your sister, so don’t be afraid.”

"I won't harm you, and you don't need to worry about violating ethics. This cultivation method is just about mutually stepping on each other's yin and yang spiritual energy."

Thinking of this, Lin Tian's eyes lit up with joy.

Mobilize the spiritual energy within your body, try to store it in your dantian, and try to make your dantian adapt to the interaction and coexistence of spiritual energy and internal force.

Lin Tian finally breathed a sigh of relief upon hearing this. His sister was right; it was just a matter of exchanging Yin and Yang spiritual energy, nothing more.

In less than half an hour, the fever on his body had completely subsided, and Lin Tian returned to normal.

Lin Tian nodded to the Empress, then circled her once more, feeling that the power within him had more than doubled compared to before.

"I never expected that mutual cultivation could achieve such peak results. Judging from the cultivation level in my body, it is much higher than my first love."

"No wonder in ancient times, cultivation advocated the mutual complement of yin and yang and the combination of two cultivations. Of course, those were things that could only happen between husband and wife."

The Empress was overjoyed.

"As expected of me! I actually came up with this idea. My brother and I have both improved our skills. As long as we work hard, I believe that in time we will definitely become the overlords of this secluded place."

"Hahaha!"

"Great!"

"Once I transform into human form, I can take my cheap brother to the Netherworld to enjoy a life of luxury."

Hearing his sister's joyful words, Lin Tian was also filled with emotion.

The Nine Netherworld Empress never expected you to be such a sentimental person. Although you initially looked down on me, you are ultimately a person with a conscience, unlike that stinky third sister.

Lin Tian nudged the Empress's tortoise shell with his head, signaling her to leave quickly.

Although the crocodile has been killed, it doesn't mean that the bloodshed won't attract other crocodiles.

They've already eaten their fill, and there's still one crocodile core left to consume. Even if they kill more crocodiles, they still won't be able to finish eating them all!

It's better to keep them and hunt them when we're hungry, so we can eat them fresh.

The Empress nodded in understanding. The two climbed out of the water and were just about to bask in the sun when the Asura Goddess's scream came from the cave entrance.

"what!"

"Help!"

Looking towards the sound, they saw an incredibly ugly chimpanzee chasing and attacking the goddess of asura.

Clearly, the Asura Goddess's cultivation was insufficient, and she was chased and left in a sorry state by the black gorilla.

As soon as he ran out of the cave, he saw Lin Tian and the Empress, and immediately ran to them to beg for mercy.

"Brother and sister, please help me!"

"Ugly! No! Brother, please save me! If you save me today, I will never be your enemy again. I beg you, please save me."

"Woo..."

The Asura Goddess was being chased with nowhere to run, so she circled around Lin Tian and the Empress.

Thinking to myself, "If this chimpanzee kills me, neither of you will escape either. Let's see if you'll make a move."

The chimpanzee circled around, its head spinning, and was about to pounce on the Goddess of Asura when Lin Tian, ​​with his bamboo strength, leaped up and bit its neck.

"Ow!"

A deafening roar erupted as the chimpanzee struggled desperately to fight Lin Tian.

Seeing this, the Empress stepped forward, bit the chimpanzee's tail, and pulled it backward.

Lin Tian seized the opportunity and pulled in the opposite direction, causing the chimpanzee to howl in pain.

However, due to its enormous size, even with Lin Tian and the Empress working together, they were unable to completely suppress the chimpanzee.

Just as the chimpanzee was about to escape, the goddess of asura bared her sharp teeth and bit down on the chimpanzee's belly. The chimpanzee struggled violently, but the force was exactly the opposite, and the goddess of asura tore off the skin on its belly.

Seeing this, Lin Tian praised him.

"You're great, Third Sister!"

The moment Lin Tian let go, the chimpanzee tilted its head back, preparing to break free and escape.

Lin Tian seized the opportunity, lunged forward, and bit down again on the already torn neck, holding on tightly and refusing to let go.

The chimpanzee gradually stopped struggling and died completely in less than half an hour.

The Goddess of Asura smirked smugly: "See? I've already broken through to level five, isn't that amazing?"

"Hahaha!"

"If I hadn't stepped in, you two turtles might not have been able to subdue this chimpanzee."

The Empress rolled her eyes at her, annoyed. "Before my cheap brother and I arrived, I wonder who was being chased all over the place..."
