In the square, tens of thousands of people looked up at the dark clouds that suddenly appeared in the sky, and the expressions on their faces were extremely wonderful.

The dark clouds gathered very quickly, and it didn't take long for the black clouds to overwhelm the sky, and the sound of thunder was not heard among the clouds, which suddenly shrouded the square in an oppressive atmosphere.

Thundered!

The thunder was rolling, and in front of such Tianwei, whether it was the people of the major families or the other audiences, their faces were pale and their eyes trembled.

Only Cui Lao looked at the sky frantically, his old cheeks rose with a touch of joy, and the whole person trembled with excitement.

"Dan, Dan Lei!"

The shock in Cui Lao's heart made him speechless, as a veteran three-star alchemist, he had a deep understanding of the four-pattern pill.

The four-pattern elixir requires the power of space to be refined, and if it is successfully refined, the alchemist needs to bear the thunder.

"Wait a minute...... Dan Lei!"

Cui Lao's face changed, and he looked at Chu Han in shock, only to see that Chu Han was still there to seriously complete the fusion of the pill, and he would soon condense into a pill!

"Hurry, hurry, go and dissuade Chu Han! You can't become a Dan! You can't become a Dan! You can't become a Dan! You will rain down Danlei!"

Cui Lao was so anxious that he ran towards the high platform, the alchemist's Dan Lei was the same as the Tianxuan Realm's thunder, he had to cross the tribulation himself, and others couldn't help!

Wow!

Cui Lao's words immediately caused a panic, and everyone in the audience looked up at the dark clouds in the sky, and under such heavenly might, everyone's hearts were full of throbbing.

"Dan Lei ......"

The heads of the three major families stood up suddenly, their pupils shrank faintly, no one thought that Chu Han would refine the four-pattern pill under such circumstances.

"Once the pill with more than four lines is born, the energy contained in it will lead to Dan Thunder and rain down on the alchemist!"

Bai Junhao said in a trembling voice, he has been the chief alchemist for many years, and it is the first time he has seen the thunder descending from the sky, and the shock in his heart is incomprehensible.

The situation on the high platform, the thunderclouds in the sky, and the reaction of the audience made Su Muxi's little hands clenched, and his face regained a touch of nervousness.

"Dan Lei ......"

Su Muxi bit her lip and looked up at the dark clouds in the sky that had become heavy, and suddenly felt a sense of oppression.

For a while, everyone was not calm, only Chu Han on the high platform, his face was still serious and serious, focusing on alchemy.

Whew......

The liquid medicine in the Dan furnace turned faster and faster, and with the initial fusion, everything became much easier.

As the progress of the fusion of the liquid medicine accelerated, the lightning in the sky became more and more dense.

Everyone has a feeling that the thunder is about to fall!

Airplanes......
