In the jungle, an emaciated figure was sitting silently on the ground, his eyes closed, and up and down his body, a stream of pure and fierce black and white aura was constantly entwined, forming a yin and yang fish formation, swallowing up all the air around it.

Looking around, he could faintly see that on the top of the young man's forehead, there was a small and pure spiritual cyclone pouring down, making the aura in the latter's body become stronger and stronger......

In addition to swallowing this aura, the young man's left hand also held a spirit crystal that exuded a rich aura, and in his right hand, he held a black demon core with bloodstains!

Under the effect of the Yin and Yang Recipe of Creation, the two objects in the young man's hands are also shrinking at a speed that is visible to the naked eye, turning into the purest energy, and little by little the Yin and Yang True Yuan in the body is growing!

In a moment, the demon core and spirit crystal were directly turned into powder by the young man, floating in the air, seeing such a rapid speed, the face of a shadow floating not far from the young man couldn't help but show a little surprise.

In fact, she had seen it many times, but every time, she still couldn't suppress the surprise in her heart, to be honest, a spirit crystal, even if it was a fifth-level martial artist in the Tiangang Realm, would take a long time to refine it before it could be absorbed, and this refined spirit crystal would also lose some pure energy.

Although the true qi in Xiao Tianchen's body has now transformed into a true element, the refining speed has far surpassed that of martial artists of the same level, and even martial artists in a small realm who are two or three times higher than him are difficult to match.

Not only that, but the energy in this spirit crystal, the latter is not at all, and the demon core, although it is the demon core of the seventh demon beast of the Tiangang Realm, for some martial artists who have reached the level of the Spirit Martial Realm and the Earth Martial Realm, it is not difficult to refine and devour.

But I have never seen someone like Xiao Tianchen who accepted all the orders.

Seeing that the latter's aura was growing stronger little by little, Tianxuan also shook his head slightly, and with a move of his jade hand, he summoned back the Chixiao Sword standing beside Xiao Tianchen.

The slender fingers gently stroked the blade of the sword, and said with a nostalgic expression: "It seems that your master is not capable of completely controlling you now, and your current edge is indeed too dazzling, so I can only seal you for a while." ”

Speaking of this, Tianxuan turned his attention to Xiao Tianchen again, and said with a relieved face: "Don't worry, your new master, you will have the strength that can match you in the near future, so you can sleep for a while." ”

As soon as the words fell, a soft crisp sound immediately erupted from the pitch-black blade, and a charming smile appeared on Tianxuan's face when he heard this sound.

The jade hand caressed, and a faint golden light attached to it, as if forming an invisible chain, blocking the entire Chixiao Sword.

The light dimmed, and the chains that intertwined the blades of the sword simply disappeared, as if they had never appeared.

However, as the light faded, the entire Chixiao Sword also became silent, and there was no longer the original sharp aura.

The entire ink sword looked like an ordinary long sword, and no one would have imagined that this sword was actually a divine weapon that had reached the heavenly rank and above......

After sealing the Chixiao Sword, Tianxuan also gently took off the space ring from Xiao Tianchen's finger, and from the space ring, he took out the materials that the latter had bought in the auction house before, and with a move of the jade hand, a cyan flame rose from the palm of the mutton fat-like hand, and immediately began to calcinate those materials, condensing the essence of them into a thin sheet......

However, those beautiful eyes were cast on Xiao Tianchen, feeling the fluctuations emanating from the latter, and she also knew that the latter had reached the edge of a breakthrough.

"This progress...... It's fast enough......"

The murmur fell, and a fierce aura suddenly swept out of Xiao Tianchen's body!

In the dantian, the black and white colors are in one place, and the yin and yang true elements that exude purple light are constantly intertwined, as if they are forming something.

Wow......

Another spirit crystal turned into powder in Xiao Tianchen's hands, looking at the Yin and Yang True Yuan that was growing in his dantian, Xiao Tianchen's brows also frowned slightly, it stands to reason that he should have reached the edge of breakthrough, but at this moment, it is like an unfillable belly, and it still needs great energy......

As soon as he thought of this, Xiao Tianchen's hands also grabbed towards the void, and two spirit crystals exuding a rich aura appeared directly on his hands, constantly shrinking with the operation of the Yin and Yang Technique of Creation.

The current Xiao Tianchen, although in order to buy some materials and the Heavenly Blood Seal, there are still a lot of spirit crystals left, and he also snatched Liu Cen's space ring, although the remaining spirit crystals in it are not as good as Xiao Tianchen's expenses this time.

But it also made up for some of his financial losses.

If it weren't for the fact that he needed this spirit crystal as a common currency to walk in this middle martial spirit realm, he would have devoured all these spirit crystals a long time ago.

However, with the disappearance of the spirit crystal, Xiao Tianchen's brows became tighter and tighter.

He obviously felt that he was only a stone's throw away from the fourth level of the Tiangang Realm, but now since he reached the third level of the Tiangang Realm, the spirit crystals devoured, including the spiritual energy swallowed in the auction house, were probably no less than a hundred, which was enough to make the ordinary Tiangang Realm first level reach the fourth level of the Tiangang Realm.

But when you come to him, you can't even break through?!

"It seems...... I have to work harder to break through before I can break through to the fourth level of the Belt Tiangang Realm. ”

Xiao Tianchen muttered lightly, and took out more than a dozen spirit crystals again, bringing the Yin and Yang Technique of Creation to the extreme!

A terrifying devouring force swept out in an instant, directly devouring all the dozen or so spirit crystals! The Yin and Yang True Yuan in that body suddenly reached a full state!

At the same time, there was a sudden rumbling sound in the dantian!

......

A strange force seemed to emerge from the broken barrier, and it poured directly into Xiao Tianchen's limbs.

Seeing this appearance, Xiao Tianchen's face also had a slight paleness, and as his voice fell, a terrifying aura suddenly swept out of his body!

The fourth level of Tiangang Realm has become!

At the same time that he couldn't help but breathe a sigh of relief, the Yin and Yang True Yuan circling in his body also trembled suddenly!

An invisible force swept away immediately!
