Ye Yun said solemnly to the black hell and the cold emperor.

At this time, the black king of hell and the cold emperor of heaven heard that they could improve their spiritual power, but they were not polite to Ye Yun, or even eager to try.

Both of them are amazing in their talent, cultivation and spiritual strength.

But compared with Ye Yun, it's much worse.

Therefore, many times when they face Ye Yun, they will be a little embarrassed.

The gap between them and ye Yun is getting bigger and bigger, and they can't keep up with Ye Yun.

"Why don't we see who has more mental power upgrades?"

Ye Yun made a proposal.

Of course, I didn't deliberately want to upgrade the number of times through mental strength, so as to pretend to force in front of them.

Even ye Yun can almost believe that he is not as good as the two in terms of the number of spiritual power upgrades.

First, ye Yun has used the gas in the magic particles to upgrade his mental power more than once. In this way, the power of these gases to upgrade his mental power will be weakened.

The black king of hell and the cold emperor of heaven are the first to use them to upgrade their spiritual power, which will help a lot more.

Second, the higher the mental strength, the more difficult it will be to continue to upgrade. Ye Yun's mental strength has reached 23 grades. It's as difficult to continue upgrading as climbing to heaven.

The spirit power of the black king of hell has reached 15 grades high, while the spirit power of the cold emperor of heaven has only reached 14 grades medium, so it will be much easier for them to upgrade their spirit power.

For ye Yun's proposal, the black king of hell and the cold emperor of heaven certainly agreed with both hands.

Although they know ye Yun is making them happy, it is still a surprise for them to surpass Ye Yun once.

The absorption began and lasted for five days.

Five days later, the aura transformed from the gas in the magic particles has been completely absorbed by the three people.

However, this does not mean that ye Yun will have no aura support in the future, because ye Yun also has a large magic particle that can continuously grow small magic particles.

It just takes a process to grow.

Five days later, ye Yun's spiritual power was upgraded from grade 23 to grade 24, and it was only grade 24 elementary.

But this is already a huge leap for ye Yun.

The spiritual power of the black king of hell was upgraded from fifteen grades higher to seventeen grades elementary.

As for Leng Tiandi, he upgraded more directly from 14 grade medium to 16 grade high.

The final winner is Leng Tiandi.

Of course, this is almost expected, because the original spiritual level of lengtiandi is the lowest.

After leaving the customs, the cold emperor and the black king of hell are obviously very excited. For them, their spiritual power has definitely achieved a very ferocious leap.

Moreover, with the leap of spiritual power, their perception and comprehensive combat ability have been greatly improved.

Next, there are ten days before the underground world opens.

In these ten days, ye Yun and others were not idle and began to try to upgrade their cultivation.

If you want to upgrade your accomplishments, of course, the best way is to fight, especially those whose accomplishments are equal to or better than yourself.

The cold emperor and the black king of hell went much better. Looking at the immortal killing alliance, there are still many people whose accomplishments surpass them.

Not to mention the existence of Leng Xiaolian, goddess and shadow God, even the Xiaoyao wine emperor and the beautiful fairy are more than enough to compete with each other.

Ye Yun had some difficulties. He thought the shadow God could compete well, but now the shadow God was defeated by Ye Yun in three moves.

The goddess's words are similar to Ye Yun's combat effectiveness, but ye Yun can't go all out to fight with the goddess. There is no feeling of life and death at all.

Fortunately, five days before the underground world was opened, Tiantu came as a guest.

Tiantu, the first person under the hidden emperor, demon God and unparalleled female emperor, is definitely a good competition object for ye Yun.

Above the martial arts arena.

"I will suppress my accomplishments to about the Ninth level of the imperial level and the fifth level of heaven, and then compete with you!"

On the Tai Chi platform, Tiantu spoke to Ye Yun, who stood opposite.

On the huge Tai Chi battle platform, at the moment, layers of Tai Chi defense around have been opened, which ensures that Tiantu and ye Yun can fight wantonly without worrying about the impact of afterwave energy.

"I think you'd better not suppress cultivation, so that we can fight more soundly!"

Ye Yun suggested.

Let alone let Tiantu, even the immortal killing allies in the martial arts arena were shocked.

They all know that Tiantu's accomplishments have reached the tenth heaven of the imperial level, and he has just completed the upgrade a few days ago, reaching the fifth heaven of the tenth heaven of the imperial level.

Although there is still a gap between such accomplishments and the hidden emperor, others are absolutely dominant.

Ye Yun's accomplishments only reached the eight levels of heaven and five levels of the imperial level.

In fact, when Tiantu said that he would suppress his accomplishments to the Ninth level of the imperial level and the fifth level of heaven just now, people thought Ye Yun was going to lose.

"I think it's better to forget it. Although I know that you have strong leapfrog fighting ability, I have experienced countless battles and have sufficient fighting experience. Moreover, even if you suppress to the ninth floor of the imperial level and the five levels of heaven, it's a big level higher than your cultivation. Such battles are already very unfair to you!"

Tiantu replied, looking serious.

Seeing Tiantu's insistence, ye Yun didn't say anything.

I just prayed in my heart that Tiantu would be more resistant to beating.

Battle open.

Tiantu didn't talk big. Although Tiantu stubbornly became a bald old dog for many years because of a sad relationship, his cultivation has been abandoned for many years.

But with the invasion of the demon clan, he has changed back. He has fought for several times during this period and has completely found that feeling of battle.

A few days ago, I even completed an upgrade.

Suddenly, a vast amount of gas was produced.

Like the name of Tiantu, the gas is extremely fierce and cold, just like the killing gas that can kill Tiantu.

On the Tai Chi battle platform, he was immediately occupied by the map recorder released by Tiantu.

In his killing spirit, he is equivalent to the existence of absolute dominance level.

"Come out and give you ten chances to fight. If you can bring me trauma once, no, you only need to touch my body once through the most intense killing gas around my body!"

Tiantu said proudly.
