For ordinary Ten Halls Ghosts, inert energy can be said to be their supreme magic weapon to improve their strength!

In order to improve Li Xian's qi at the beginning, Jade Butterfly once took him through the space of the Central Axis World to snatch the inert energy that they had easily refined from the hands of those space hermits.

Refining inert properties is rare, and the process of refining is even more difficult. Therefore, for those space hermits, refining hundreds of years of inert energy to be able to increase their vitality is already a high level of creation.

There was so much inert energy in front of them, which they couldn't have imagined.

But no matter how good things are, there is an upper limit.

Just like the Ghost King's Qi Enhancement Pill, although the number of qi increases is extremely fast, it is only useful for strong people with less than 200 qi points; The strength reaches or exceeds two hundred lives, and there is no more fusion.

Although inert energy does not have such a specific limit, it is also limited.

For example, a relative amount of inert gas, for a strong person who only has one life, it may be able to help increase the number of ten lives; For a strong person with a hundred vitality, it can only help improve the vitality of one life; But for a super strong person like Li Xian who has four hundred and seven qi numbers, he can't even increase the qi number of one ten-thousandth of a lifetime; For an old monster with six hundred vitality, even if it has an effect, it is negligible.

Even the rare spiritual root energy that was exclusive to the ghost king did not have a too obvious effect on the improvement of Li Xianqi's qi, not to mention the relatively common and ordinary inert energy.

The reason why Li Xian felt surprised was that there was too much inert energy in the body of the "giant", so much that it could be described as jaw-dropping!

If inert energy is as scarce and precious in the eyes of ordinary strong people as diamonds are in the eyes of human beings; Then Li Xian saw so much inert energy at this time, as if human beings had seen a city made of diamonds.

The inert energy in the "giant" dantian is simply a huge energy lake!

The inert energy is much stronger than ordinary energy, and when he is in it, the aura formed by the concentration of these inert energies alone gives Li Xian a feeling of being in a tsunami whirlpool.

No wonder the old monster can strengthen the control of the ghost kings through the center of the ten thousand worlds, these inert energies are indeed not covered.

After Li Xian reversed all the heavenly and earthly treasures in the "giant" dantian into a chaotic body, he no longer paid attention to the old monster outside who was frantically smashing and scolding, and rushed directly into the center of the dantian, hovering cross-legged in this lake composed of inert energy!

He wants to take away these inert energies, not only to increase his qi number, but also to give the "giant" a blow from the bottom of the kettle.

The next moment, a huge whirlpool appeared in this "lake" of inert energy, and the surging inert energy was sucked into Li Xian's dantian, and after the high-purity extraction of the golden ghost beads, it all melted into Li Xian's three souls and seven spirits.

Although the inert energy is far inferior to the spirit root energy of the ghost king, it is more valuable than the inert energy, and in this lake-like inert energy, Li Xian's qi number has actually increased at a significant speed: four hundred and eight lives! Four hundred and nine lives! Four hundred and ten......

Li Xian only felt hearty!

He hadn't had this feeling of quickly increasing his qi number for a long time!

I didn't expect that now that I am in the place of death, I will have such a super benefit!

He was more focused on fusing together, anyway, there were those heavenly and earthly treasures that had been reversed into a semi-chaotic body, and the old monster couldn't help it.

The Jade Butterfly was originally staring at the tumbling dark clouds in the Ghost King space, and had been worried about Li Xian, but at this time, she couldn't help but be surprised to see the dark clouds in the sky instantly transform into golden clouds.

Under the condition that Li Xian was in a normal state, although the clouds in the Ghost King Space were golden, they were quiet and stagnant, but at this time, even this golden cloud was tumbling.

The golden clouds are closely related to Li Xian's state and mood, at this time the golden clouds are rolling, how excited should Li Xian be?

Jade Butterfly knew that she couldn't help Li Xian at this time, all she could do was that when Li Xian asked her, she offered advice in time, and remained silent the rest of the time.

Only half an hour had passed, and the inert energy in the "giant" dantian had been consumed by Li Xian by one-third.

And Li Xian's strength has also increased from the initial four hundred and seven angry numbers to four hundred and thirty angry numbers!

His strength improved too quickly, and Li Xian could feel that his strength was increasing rapidly, and his hearing, vision, and sensitivity were ...... It has also been multiplied.

When Li Xian's qi number reached four hundred and forty lives, the rate of increase slowed down, but it continued to increase.

By the time he reached four hundred and forty-five births, the increase in qi number had been somewhat intermittent.

At this point, Li Xian understood why the old monster didn't fuse these inert energies, with the strength of the old monster's six hundred qi numbers, it would be difficult to improve again.

Li Xian was originally thinking about whether he could use these inert energies to surpass the old monster in one fell swoop, but now it seems that this is completely impossible!

The stronger Li Xian's strength, the more inert energy he would lose by increasing his vitality.

When his strength reached four hundred and fifty qi numbers, seventy percent of those inert energies were lost.

When his qi number reached four hundred and fifty-three, more than ninety percent of his inert energy had been lost.

Just increasing the number of three qi qi would lose more than twenty percent of the inert energy!

The most important thing is that when Li Xian's qi number reached four hundred and fifty-three lifetimes, these inert energies could no longer help him improve.

Li Xian had no choice but to stop.

At this time, there were still five or six percent of the inert energy left in the "giant" dantian, and when Li Xian was thinking about how to exhaust this inert energy, he suddenly thought of the jade butterfly in the ghost king space.

The Jade Butterfly only has two hundred lifetime qi, and if she is allowed to fuse these inert energies, she is afraid that she will ascend faster.

Thinking of this, Li Xian directly rolled the jade butterfly out of the ghost king space.

"Huh?" Jade Butterfly looked up at the surroundings and wondered, "I saw that the clouds above your Ghost King Space were golden, and I thought you had escaped, but I didn't expect——"

Before he finished speaking, Jade Butterfly said "Huh" again: "Wow, Li Xian, your strength has increased so much!" ”

"Now it's your turn to improve your strength!" Li Xian smiled, "What do you look at these?" ”

At this point, the Jade Butterfly's gaze shifted from Li Xian's body to those inert energies, and he issued a "huh" for the third time: "...... Oh my God, so much inert energy! ”

"The old monster can't get in at this time, you can rest assured that these inert energies have been fused!" After Li Xian finished speaking, he added, "I can't rely on inert energy to improve my strength anymore, these are all yours, you don't have anything left, it's all fused to it!" ”
