Luo Zhen's eyes were filled with surprise. This must be because he killed Lei Lu higher than the level, so he received such a generous reward!

After all, he is in the middle stage of the Demon King Realm, while Lei Fu is a powerful man in the second level of the emperor. The levels of the two are very different.

Moreover, Lei Nu is also the Silver Dragon Emperor of the Silver Dragon Clan, and he is a big boss with a big identity!

All the reasons combined, which led to him gaining five million experience!

After the city ranking competition, Luo Zhen obtained a lot of advanced spiritual pills and advanced spiritual medicines. By refining those resources, his experience value has increased to more than three million.

Now, with these five million, his experience value has accumulated to more than eight million.

If you want to break through to the late stage of the Demon King Realm in the middle stage, the experience value you need is only seven million, which means that Luo Zhen has reached the conditions for upgrading!

Sure enough, the system's voice sounded in Luo Zhen's mind again.

"Host, your experience value has reached the critical point. Have you upgraded?"

"Yes!" Luo Zhen said with the excitement in his heart.

"The experience value has been deducted and is being upgraded..."

As soon as the system finished speaking, the vitality between heaven and earth suddenly fluctuated.

The originally clear sky became dark in almost the blink of an eye. Layers of dark clouds gathered above Luo Zhen's head, and there were slight lightning in the dark clouds.

These electric lights skyrocketed at a speed visible to the naked eye. In just a moment, the electric light changed from the thickness of a hair to the size of a chopstick.

After a moment, the lightning gathered and condensed into a blue light as thick as an arm, slamming down from the sky!

"Click!"

The blue thunder fell from the sky and hit Luo Zhen's head hard. In an instant, Luo Zhen was flooded with lightning.

However, Luo Zhen was prepared for a long time. Before the thunder was struck, he activated the Qingyu Spirit Body.

Then, there was a dazzling green light in the lightning, which resisted most of the lightning damage. Even if a small amount of thunder damages Luo Zhen, the Qingyu spirit body could repair it in time.

"What's going on? Luo Zhen, you are going to get through the tribulation?!" Bai Susu flew quickly from afar and asked anxiously when she looked at Luo Zhen.

Because she was worried about Luo Zhen, she chased him, and the boss Dayuan discovered that Luo Zhen was passing through the thunder tribulation.

"It's okay, don't worry about me. I have a spirit to protect myself. This level of thunder tribulation cannot hurt me." Luo Zhen's voice came out of the lightning lights.

Upon hearing this, Bai Susu's hanging heart could finally be let go, and she did see that the green light emitted by Luo Zhen was very powerful, and she was not afraid of the thunder disaster at all.

Looking at the green light emitted by Luo Zhen, Bai Susu suddenly remembered that when she was in the ant nest, she was fighting against the thunder tribulation of the Second Heaven of the Demon King. Luo Zhen emitted green light to help her fight.

Luo Zhen's thunder tribulation did not last long, and when the time passed, the lightning disappeared.

After the lightning dissipated, Luo Zhen, who was shirtless, showed his breath, at the same time, doubled his aura.

Seeing Luo Zhen's upper body without clothes, Bai Susu turned her head embarrassedly and looked to the side.

"It seems that you have to get a good clothes or a good armor magic weapon in the future, otherwise every time you pass the tribulation, your clothes will be smashed by the thunder tribulation."

While complaining, Luo Zhen took out the spare new clothes from the space ring and put them on her body in a quick way.

Just as I put on my new clothes, the sound of the system started to ring.

"The host successfully survived the thunder tribulation!"

"Congratulations to the host, you have been promoted to the late stage of the Demon King Realm!"

Without caring about the system's prompt, Luo Zhen turned his head to look at Lei Nu's corpse.

The original shape of the Thunder Rage Silver Dragon is 500 meters long. Even if the giant dragon body is cut off by Bai Susu, the rest will be extremely impacted.

At this time, the 500-meter-long giant dragon body had fallen from the sky and floated quietly on the sea surface. Bai Susu also turned her head and didn't look at Luo Zhen.

Luo Zhen's eyes rolled, fell from mid-air, and came to Lei Fu's side.

Looking at Lei Nu's giant dragon body that was more than 500 meters long, Luo Zhen smiled slightly and then activated the swallowing function!

The next moment, a crazy whirlpool suddenly appeared in front of him, and the whirlpool burst out with a terrifying suction force, trying to suck the thunderous dragon body into the whirlpool.

Affected by the suction force of the vortex, the thunderous dragon body quickly turned into a torrent of essence and blood, and penetrated into Luo Zhen's mouth.

After just a few breaths, the body of the thunderous dragon, which was more than 500 meters long, was left with only a layer of silver-scale dragon skin with golden silk.

Luo Zhen smacked his lips with satisfaction, then sucked his hands and sucked the silver-scale dragon skin into his hands.

"As the Silver Dragon Emperor, Lei Nu must be extremely powerful and valuable. If you don't say anything, you will accept it!"
