A conspiracy was unfolding around the desert, with the target being the female dragon.

Li Dao didn't know that he was currently gathering heavenly and earthly treasures.

Every world had places that were especially rich in spiritual energy, and these places were most likely to produce heavenly and earthly treasures.

Vermilion fruit, golden dragon-shaped grass, purplish black flower bud. There were many, many precious herbs that Li Dao could not possibly know all of them.

After taking a few pills, Li Dao's primeval essence rose up like a rocket.

The Pre-Sky Realm martial artist was still in the Qi Refining stage, and he trained his inner strength and true qi. After reaching the Xiantian realm, one's zhen qi had been compressed into liquid zhen yuan. Every move of his was extremely powerful and was extremely difficult to defend against.

After the Upper Sky Realm was the Grandmaster, the Great Grandmaster. In order to break through to the Grandmaster Realm, he had to refine all of his liquid true essence into an Aurous Core.

After becoming a Grandmaster, Li Dao was not clear on the level of the Green Lotus Sword Manual. However, after reaching the Grandmaster Realm, one would have reached the peak of mastery.

Li Dao didn't think too much about it. When he reached the Grandmaster Realm, he had long since left this world. Moreover, this was the martial arts system, and in the future, it would change to the immortal martial arts system.

Liquid true essence circulated through his meridians, continuously refining the spirit energy of the heaven and earth and the energy provided by the heavenly and earthly treasures. One round after another, the small streams of true essence constantly grew in size while simultaneously nourishing and strengthening his body.

One treasure after another was consumed by Li Dao. His true essence continued to grow. In just two or three days he had reached the peak of the early Xiantian realm. He was just a step away from reaching the middle Xiantian realm.

However, this step could not be taken. The gap between realms was a barrier.

From the early Xiantian realm to the middle Xiantian realm, and then to the late Xiantian realm, these were all minor hurdles. From the Xiantian realm to the Grandmaster realm was a natural chasm.

Shaking his body, Li Dao stood up and continued to search for the heavenly and earthly treasures.

This secret realm was not big. It covered an area of several dozen miles.

He suddenly remembered that Gu Mutian had brought out the Rainbow Crystal Mother from a cave here and then forged the Dragon Soul Saber and Phoenix Blood Sword. Then, where was the cave?

Li Dao rubbed his chin as he quietly pondered. The secret realm wasn't big. If there was a cave, he would have found it long ago.

A rumbling sound rang in his ears. Li Dao's eyes lit up as he looked at the rainbow underneath the waterfall in the distance.

He remembered that many waterfalls had water curtain caves behind them. Was this the same after this waterfall?

As soon as he thought of this, he took a deep breath and flew into the waterfall that weighed over a thousand kilograms.

As expected, his guess was correct.

Behind the waterfall, there was indeed a cave. The cave was filled with rainbow-colored light, as though one was in a crystal palace.

Li Dao carefully walked forward, deeply afraid of being attacked by the unknown creatures.

All the caves in the secret realm were occupied by spirit and magical beasts of strange shapes and sizes, so he had to be careful.

For instance, the appearance of a python, a demonic dragon, these things weren't strange at all. Whether it was Wuxia World or Immortal World, this was a common practice.

However, Li Dao was disappointed. There was no giant python or dragon in this cave.

Drip, drip, drip. Water dripped down from the ceiling and hit the smooth stones on the ground, producing a clear and melodious sound.

Li Dao followed the rainbow colored light and walked forward. A pool of water had almost blinded him.

The pool was small and oval in shape, with a diameter of about three meters.

The water in the pool was crystal clear, sparkling with rainbow-colored light, illuminating the entire cave.

If it was just looking, Li Dao would not be surprised. However, he could feel the boundless spiritual energy in the water. This pool was simply filled with liquid true essence.

"Today is the day to break through to the middle Xiantian realm." Li Dao revealed a happy expression. He quickly took off his clothes and threw himself into the pond with his sword.

As the sparkling water wrapped around his pores and trickled into his body, Li Dao couldn't help but begin to groan.
