It took Ye Chen a full two months to convert a body of true yuan into mana, but fortunately, they are now in the underworld, and they don't need to eat under the rules of the special underworld, and they can be replaced with soul power.

When the last bit of true element was converted into mana, Ye Chen opened his eyes and exhaled lightly, opening the attribute ability panel, which showed that he only had sixty years of mana now.

The transformation of true qi into true yuan needs to be compressed, and the transformation of true yuan into mana does not need to be compressed, his original true qi of five hundred and sixty years, mixed in the Great River Valley for almost a year and accumulated for nearly forty years of true qi, just six hundred years, under the compression of ten to one, there are sixty years of pure true yuan left, and finally there is one jiazi mana left.

Although the mana is only sixty years, his current strength is more than ten times that of the past, and the mystical mana can bring out all the flying sword magic weapons and Dao magic powers, and the farthest distance of the sword before was no more than one kilometer, and now he can take the head of the enemy dozens of kilometers away.

And this is not the end, he still has potential points to open.

Eyes fell on the attribute ability panel, the name of Emei Qi Refining Qi Technique has not changed, but the potential points that need to be consumed to improve once have skyrocketed, in the past, a thousand potential points to improve a layer of Emei Qi Refining Qi Technique can increase ten years of true qi cultivation, but now it takes a full 20,000 potential points but can only increase ten years of mana, a difference of nearly twenty times.

But it's normal to think about it, after all, true qi and mana can't be compared, and it's not much different when converted.

Similarly, the previous fifty layers of Emei Qi Refining Qi Technique were also reduced proportionally, and now there are only five layers left.

Without thinking about it, Ye Chen directly consumed a full two million potential points and raised the Emei Qi Refining Technique by one hundred layers, increasing his mana by a total of one thousand years.

It's not that he doesn't want to continue to improve, but he has reached a bottleneck when he has risen to the present, and his mana has risen sharply for a thousand years in an instant, and it has reached a point comparable to that of ordinary earth immortals, but I am afraid that ordinary earth immortals can't compare to him, such a powerful mana, even with his current Purple Mansion Divine Soul, it is difficult to accommodate, and he must have a strong divine soul and physical body to continue to improve.

The physical body is easy to improve, even if he does not deliberately improve, the power from the Chaos Demon God will make his physical body continue to grow, which cannot be stopped from being uncontrollable and irreversible, as long as he does not die, the physical body will continue to be powerful, and finally reach the realm of immortality and immortality of the physical body.

And the Divine Soul is not to mention, as long as you recover the many divided Divine Souls scattered in the Underworld and the Shushan World, you can immediately become powerful.

And in the final analysis, it is time, and after a while, it will naturally become stronger, and it will be able to improve again.

When he opened his eyes, two rays of light shot out of his pupils, Ye Lianxing felt a sharp light in front of him, like lightning exploding, and then looked closely but there was nothing, her eyes fell on Ye Chen, she tilted her little head in some confusion, and asked:

"You've already transformed your true element into mana?"

He nodded:

"Yes, fully converted!"

"Are you really sure you'll survive the Compound Tribulation?"

"Of course, I'm sure, when I take back the split soul, I don't need to take it all back, as long as I take back half of it, I'll be sure to force the reunited heavenly tribulation."

"That's good!"

Senior sister is also happy for him.

After waiting for a few days to adapt to the soaring mana, Ye Lianxing also transformed his true qi into true yuan, and the two of them came out of the place where they had been hiding for several months, and walked through the stone forest to an empty wasteland, and at a glance saw a group of more than a dozen patrols in front of them rushing towards them, shouting loudly from afar:

"The front has left the battlefield, leave quickly, otherwise it will be dealt with according to military law, and it will be killed!"

Ye Chen laughed, turned his head to look at his senior sister, and said with a slight smile:

"Are you ready?"

She nodded, stretched out her weak and boneless little hand, Ye Chen reached out to hold her soft little hand, a ball of white light wrapped them and rose into the sky, crossing the sky like a meteor, the cavalry stopped their horses, their heads turned in the direction of the meteor's fall, and they were stunned for a long time before the leader of the bone knights shouted:

"Keep patrolling!"

No of his subordinates stupidly jumped out and asked why they didn't continue to chase, and the fools were all dead on the battlefield.

"Cool!"

The first time I tried to use the Escape Light Dao Technique, the speed was amazing, and in an instant, it was several miles away, and I soon left the battlefield of the Yuyin Ghost Realm and the Ghost Luo Realm in the Great River Valley, and officially entered this underworld.

Flying thousands of meters in the air, overlooking the bottom from above, the endless earth is gray, covered with a layer of faint gray mist, from time to time I see a black breath spewing out from the ravines of the earth, and occasionally I see a huge head full of bones and oracle bone spurs out of the ground.

This is a life unique to the underworld, bounded between life and death, feeding on yin qi and death qi, and occasionally devouring its own kind or ghosts.

The direction Ye Chen was moving in was the closest group of divine souls to himself in his senses, and maybe there were lost souls closer to him, but the closest one he could sense was this one, in his sea senses, it was a fist-sized fireball, which was constantly sending him signals, indicating his direction.

The closer he got to the target, the clearer and stronger the signal became, Ye Chen flew for almost half a day, and the signal was already very clear.

But at this time, his speed had to slow down, and the two living people flew in the air of the underworld, which was not stingy with two pieces of fat dangling in front of countless hungry ghosts, and had just left the big river before, at the junction of the Jade Yin Ghost Realm and the Ghost Luo Realm, it was okay, the evil qi of the battlefield could deter the evil beasts and ghosts, but when they were far away from the battlefield of the two realms, far away from civilization and into the wilderness in terms of the Yang World, they began to encounter all kinds of ghost beasts and ghosts, as well as some strange things to attack them.

In order to reduce the target, they had to land and fly close to the ground.

They did not dare to walk on the ground, there was a thick layer of gray gas on the ground that almost condensed into a viscous cloud, and stepping on it was like stepping on it like stepping in water.

At first, he was down-to-earth, and after taking a few steps, he felt that something small in the sticky gray mist seemed to be desperately burrowing into the pores and other holes in his skin, and he reached out and fished in, and grabbed many thin, long, and black insects like iron worms.

Ye Chen is okay, his body is strong enough now, and these insects can't break through the skin.

But Ye Lianxing is different, what a girl is most afraid of is this kind of thing, think about these things crawling all over the body to the pores and others.... It's chilling to think about drilling somewhere.

The final result was that the two of them used the qi control technique to rise into the air, hanging in the air close to the ground, the fog on the ground was only one or two feet thick, only about half a meter, and a little more than three meters per zhang, with this distance buffer, even if something rushed out of the fog, it could quickly react.

In fact, the fog is so thick that it can't hide anything big.

Five days later, the two of them passed through a hill and entered a wasteland, where the fog had dissipated considerably, and only a thin layer was attached to the ground, and the dark brown earth of the ground could be faintly seen.
