The energy in the valley suddenly became violent, and it didn't take long for the sky, which had been still clear, to suddenly turn gloomy, followed by a shocking explosion.

"What's going on?"

The silver mirror was the first to flash out, looking at the light in the sky that was as thick as an adult's arm, flashing by, and opening with a little doubt.

Then he looked at the figure sitting in the cave like an old monk in a fixed place, and not only did the sound of thunder not wake it up, but Li Mu's pair of sword eyebrows had already twisted into a pimple at this time.

"This ....."

Yinjing flew around Li Mu several times in disbelief, and finally screamed, "Li Mu, are you going to become an alchemist??"

But Li Mu didn't have time to listen to what the silver mirror was saying at this time, he just felt that his brain was about to explode, because his soul power was not strong enough, and he hadn't even reached the most basic human realm, so he couldn't see the situation in the Mud Pill Palace at this time, or if he could see it, he would definitely jump up happily.

Because at this time, inside the Mud Pill Palace, it seems to be a forest of grass houses, and above the Mud Pill Palace, there is also a cloudy cloud, and the silver arc is constantly churning and jumping in the air, It seems that it will not be long before a heavy rain falls.

These are definitely great news for Li Mu, at the beginning, he had tempered the Mud Pill Palace on the Tianwu Continent for two whole years, and he had not made the slightest progress, but now he was about to start his first advance without realizing it.

If Li Mu really succeeds in advancing this time, then it can be said that Li Mu has officially stepped into the ranks of alchemists.

The rank of the alchemist is much simpler than the cultivation, and it is divided into one to nine grades, and each grade is divided into three grades: upper, middle and lower.

And soul power also has a certain realm, that is, the human realm, the earth realm, the heavenly realm, the yellow realm, the emperor realm, and the god realm.

With the continuous upgrading of the soul power realm, its alchemist will practice a more advanced elixir, and the rank will also increase.

Although alchemists are a profession that everyone envies, every time their soul power is upgraded, they also have to face another problem, that is, the suffering of thunder and lightning, which is also the so-called heavenly thunder tribulation.

When a person's cultivation advances to the Holy Lord, it will cause a huge disturbance of heaven and earth energy, so it will attract the heavenly * calamity. The Holy Lord has seven seven and forty-nine heavenly thunders, and the Venerable Lord has nine hundred and eighty-one heavenly thunders, and when it comes to the Divine Lord, he has to bear one thousand and one heavenly thunders, so it is not so easy to stand at the top of the pyramid.

But the advancement of this alchemist is not quite the same, they have already been able to attract thunder tribulation at the beginning, because every expansion of the Mud Pill Palace also represents the enhancement of a person's soul power, the soul power can be detected in the sky, and the earth can be explored, and the power between heaven and earth can all be mobilized by soul power, so as long as it reaches a certain strength, it will attract the heavenly thunder tribulation.

This kind of thunder tribulation is still a little different from ordinary heavenly thunder, which only focuses on refining people's physical bodies, but this thunder tribulation is to temper soul power.

Just like Li Mu, at this time, the thunder tribulation has been, the soul power in his mud pill palace seems to have a pair of invisible big hands to pull it out, and then let the thunder tribulation continue to baptize, if he can survive safely, then his soul power will be completely stabilized in the human realm, otherwise, the light one will become a fool completely, and the heavy soul power will be completely dispersed by the thunder tribulation, and the consequences can be imagined.

Thundered!

Suddenly, in the cloudy sky, thunder and lightning had already taken shape, and the arc of lightning the thickness of an adult's wrist flashed.

Then a violent wind suddenly blew, and the silver mirror saw at this time that a colorful light also erupted in Li Mu's mud pill palace, and then a five-colored light cluster appeared, suspended above Li Mu's head.

"Soul power, it seems that it's really right, Li Mu is really going to advance!"

The silver mirror was overjoyed at the moment, and then it flashed out of a certain range in front of Li Mu.

However, Li Mu is only new to the human realm, so there are only seven heavenly thunders, but even so, if the silver mirror is accidentally touched, it will definitely be a place of no return.

Click!

At this moment, the first silver arc in the thundercloud jumped down, wrapped in the power of powerful thunder and lightning, tearing through the space, and smashing at the five-colored light cluster on Li Mu's head.

Sting!

A low explosion exploded in Li Mu's head, and the five-colored light cluster was instantly wrapped in a layer of jumping arcs.

"Ahh

Li Mu closed his eyes tightly and looked up to the sky and roared!

The beads of sweat on his forehead instantly fell.

After about half a minute, the leaping arc slowly faded away, but the five-colored light seemed to be much dimmer.

Click!

The second heavenly thunder followed, not giving Li Mu any respite at all, their main purpose was to completely disperse Li Mu's soul power.

Roar!

The green tendons on Li Mu's forehead surged, and his whole face had turned the color of pig liver.

It took about two minutes for the second thunderbolt to dissipate completely.

Then came the third, fourth, and fifth.....

After six paths, the five-colored light cluster above Li Mu's head was already inaudible, and it looked like it was about to be completely shattered if he was not careful.

And Li Mu has completely fallen into a semi-coma at this time, refining his soul power, and his powerful pain is not something that ordinary people can experience, so at this time, Li Mu's mind is already unclear, all he can feel, in addition to pain, is still pain, and the boundless pain not only fills his brain, but even his body hurts repeatedly, so he can only subconsciously curl up on the ground, motionless.

"Stinky boy, get up quickly, the last thunder is coming, you have to hold on!"

Although the silver mirror was far away from Li Mu, he had been paying attention to Li Mu's every move nervously.

Most of the time, the last thunder was more ferocious than the previous ones, and the sound of thunder was constantly rolling in the sky, but Li Mu had already fallen to the ground motionless.

Click!

The last heavenly thunder finally fell with a bang, and the power of the thunder continued to roar into the wind, and it was only a moment before it appeared in front of Li Mu.

"Get up, Li Mu!"

Yinjing shouted, and then the thunder had already fallen heavily on the top of Li Mu's head, and even the last two words of Yinjing were drowned in a huge roar.

And Li Mu's figure was also instantly wrapped in the silver arc and disappeared into the eyes of the silver realm.
