After seeing that Yu Yan and Liu Erlong had left the dormitory and went out, he also walked out of the room.

Yu Xiaogang stepped out of the building and walked the narrow track towards Liu Erlong's private cottage. After strolling through the same path, he arrived at the place. He had two reasons to come here, the first being that no one would disturb him and secondly the surroundings were very suitable for meditating.

Yu Xiaogang sat under a tree beside the lake and closed his eyes, and started meditating. He clearly felt the purity and thickness of his spirit-power after several circulations. Moreover, his meridians had widened a bit as compared to the past.

After continuously cultivating for the next one hour, Yu Xiaogang opened his eyes in joy. The biggest benefit he received from the " Dual-Cultivation " was that his foundation again became robust.

Not long ago, he had forcibly increased his power by absorbing the fourth spirit ring. Although it did not weaken his foundation as compared to a normal spirit-master, which can be seen from the way he beat Tang Xiao; still, it would affect his future, but now that problem has been solved.

Now even if he absorbs the next spirit ring, it won't affect his foundation, and in this happy state, he summoned his second martial spirit. A black spear rested on his right hand.

Yu Xiaogang began his spear practice, and without any sign, he entered into a wonderful state, and his movement began to gain more force. After a while, each thrust of his spear carried greater momentum than before.

" Ding! "

A metallic sound came from his spear as he thrust with the maximum momentum. Yu Xiaogang was pleased to find that he had entered the next level in his spear-cultivation.

He had reached the level of a spear-grandmaster, and after reaching this stage, each thrust of the spear carried his entire momentum, thus increasing its lethality.

He stood straight like an arrow and with his spear aimed towards the sky and thrust out while condensing all of his spirit-energy on the spear. An illusionary black dragon made up of spear qi & spirit-energy flew towards the sky, clearing all the clouds in its surroundings.

" Roar! " A dragon's roar was heard throughout the academy as it burst in the sky. Even Yu Xiaogang himself sweated a bit after seeing it first hand.

Yu Xiaogang thought of increasing his spear practice after watching it because he was not satisfied with the result. Although the strike contained massive power, it was not under his control.

Unauthorized duplication: this tale has been taken without consent. Report sightings.

He increased the weight of the spear by adding spirit-energy in it and started practicing the foundational spear technique. This practice continued for the next few hours before Liu Erlong came with Little Yan.

Liu Erlong brought lunch with her and said, " Let's eat together. "

" Okay. " Yu Xiaogang nodded, and with a single thought, the spear in his hand vanished.

" Go, take a bath. You are stinking. " Liu Erlong said while pinching her nose; only then did Yu Xiaogang noticed that his clothes were soaked in sweat.

" Okay." Yu Xiaogang scratched his head in embarrassment and jumped into the lake. After taking a quick bath, he entered the cottage to change his clothes.

Yu Xiaogang returned after a few moments, and he saw that both of them had already set up everything on the ground and were sitting on the grass. He also joined the two of them, and the three of them began to eat.

Liu Erlong had specially cooked the meal for him and Little Yan. She expectantly looked at Yu Xiaogang as he started eating. He instantly understood and said, " Well done, Erlong. " Although the food was not comparable to that of a restaurant, yet it was not bad.

" Mother, the food is really delicious, even better than what the father cooks. " Even Yu Yan chipped in.

A pretty smile hung on her face after hearing both of them as she lovingly rubbed Little Yan's head. After a while, they finished eating, and Yu Xiaogang asked both of them to stay here for the next period of time. Although they were a little confused, yet both of them nodded.

Yu Xiaogang had initially thought of using the energy from the divine core to give Erlong a spirit ring similar to that a God grants; later, he denied the feasibility of this idea because, after his calculations, Yu Xiaogang found out that a limit Titled Douluo could barely absorb a wisp of energy from the divine core.

So he planned to use his own pure spirit-energy cultivated through the Devouring Codex to cleanse her body once. Yu Xiaogang said, " Yan'er, you sit here and try to understand this. " He raised his finger and touched Yu Yan's forehead with it.

Yu Yan felt new information entering her mind as he touched her forehead with his finger. She sat down on the spot with her eyes closed and started absorbing all of the knowledge.

Yu Xiaogang was not going to give the cultivation technique which he had chosen for the little girl right now; after seeing her extraordinary performance during the journey, he decided to transmit the first layer of " Ice Paragon. "

His face showed a satisfied smile after looking at his daughter working hard. Yu Xiaogang gestured Erlong to enter the cottage.

She nodded and entered the cottage, and Yu Xiaogang followed behind her. After stepping in, he said, " Erlong, you sit cross-legged on the bed. I am going to channel my spirit-energy into your body; just circulate your spirit-energy according to mine. "

Liu Erlong had absolute trust in him and immediately proceeded to sit cross-legged on the bed. Yu Xiaogang sat behind her and told her to remove her dress.

After a moment, Liu Erlong felt a big palm on her back, and wisps of warm energy entered her body. This wisp of pure energy did not rampage after entering her body; instead, it started circulating throughout her body in a peculiar path.

" Moan! "

Liu Erlong felt as she has entered a warm spring and couldn't help herself but released a cry. She felt embarrassed, and her body started shaking, and instantly Yu Xiaogang said, " Focus, Erlong. "

After hearing him, all her embarrassment went away, and she focused back on circulating her energy. This process lasted for a long time, and wisp after wisp of energy entered her body through his palm, washing all her muscles, bones, organs, and even strengthening her meridians.

A layer of dirt drilled out of Erlong's skin and covered her entire body. Finally, Yu Xiaogang stopped sending energy and took back his palm from her rear after checking the purity of her spirit energy.

The purity and thickness of Liu Erlong's spirit energy had doubled as compared to before. Moreover, her body got refined and enhanced in the process; it also increased her cultivation talent. What Yu Xiaogang did not imagine was that she looked five years younger as the side benefit of refining her body.

" Erlong, go and take a bath. You stink. " An evil arc appeared on his face as Yu Xiaogang spoke.

Liu Erlong opened her eyes in confusion after listening to him, but after smelling the odor on her body, she couldn't care about his revenge and rushed out of the cottage and quickly entered the bathroom.
