The sky, which had been very clear just now, suddenly appeared at this moment, causing everyone to look up at the sky and look at the rolling black clouds that suddenly gathered.

Thick black clouds were dense over the area of the Lan Family Medicine Workshop, above the black clouds, lightning intertwined, several lightning bolts meandered down, shooting towards the location of the Lan Family Medicine Workshop, followed by several huge clicks.

The clicking sound entered the ears, and the eardrums of most people who shook were slightly painful, and they couldn't help but raise their hands to block their ears.

However, just when the vast majority of people reacted in this way, Na Mushan and Lan Chuan suddenly showed a completely different reaction.

The two frowned sharply and glanced at each other, and then they all spread out their bodies and swept towards the courtyard of the Lan Family Medicine Workshop, the two whirlwinds had just formed, and the figures of the two had disappeared from everyone's sight and entered the medicine shop.

After a while, everyone came to their senses and immediately followed.

"Could this be Dan Lei?!" On the way, Mu Shan suddenly spoke, and his face was full of disbelief.

But hearing what he said, Lan Chuan suddenly smiled bitterly and said, "Do you think it's possible?" Even if it was me, I could only barely refine a six-grade pill with a Dan pattern, and the success rate was extremely low, let alone refine a seventh-grade or higher pill that could attract Dan Lei."

What Lan Chuan said is the truth, there are also grades of pills, and most of the pills in ordinary circulation only have ordinary effects, and they are relatively simple to refine. Only when the pill prescription above the sixth grade can it cause vision, and Danwen and Danlei are important bases for distinguishing whether it is a high-grade pill.

At this time, Lan Chuan, although he was the No. 1 alchemist in Mucheng, it was very difficult to refine the sixth-grade elixir, and he didn't dare to try it easily, let alone the seventh-grade or above elixir that could attract Dan Lei.

Therefore, after Zaijian reached the thunder above his head, his first reaction had already eliminated it.

However, after ruling out this reason, he couldn't find a more reasonable explanation for a while, and he was a little stunned. It wasn't until he looked at the thunder in the sky again and saw that the place where the thunder fell happened to be the secret room where Lan Qinghao Wuchen was, that he came back to his senses.

However, Lan Chuan, who had just come back to his senses, suddenly changed his face and became extremely ugly.

"Oh no!" Lan Chuan snorted, not bothering to talk to Mu Shan, who suddenly turned his head when he heard the sound, he hurriedly turned towards the secret room where Lan Qing and Wuchen were, and his face was full of anxiety and worry.

Seeing Lan Chuan's movements, Na Mushan also turned to follow, his face full of doubts.

Above the sky, thunderclouds gathered more and more, covering the sky area above the Lan Family Medicine Shop layer after layer, covering the sunlight tightly, and it was dark below.

In the pastoral city of Nuoda, the Lan Family Medicine Shop is like night in broad daylight, if this is seen by others, they will definitely think that there is a hallucination.

However, it is worth noting that it is noon, the sun is hot, and most people choose to stay behind closed doors to avoid the scorching sun that can dry people, so they don't have the chance to see this spectacle.

And as Lan Chuan and Mu Shan rushed to the scene, the thickness of the thundercloud also reached the extreme, and more and more thunderbolts broke away from the thundercloud in a crowded manner, shot to the ground, and slashed towards the inner courtyard of the medicine shop.

When Lan Chuan and Mu Shan finally arrived outside the secret room, it happened that a thunderbolt the thickness of an arm slashed accurately on the roof of this secret room, and along with the lightning came there was a deafening loud noise.

Boom!

The loud sound beyond the previous one was shocking, the sound was huge, and the propagation distance was also very far, falling into the ears of Cheng Hao and his party who had just left.

Hearing the sound, several people in the group turned their heads in unison, looked at the location where the voice came from, frowned slightly, and didn't show much concern at first.

However, when these people saw that there were large thunderclouds entrenched in the area above the Lan Family Medicine Workshop, and the thunder and thunder were intertwined and split, these people all trembled in their hearts, even Cheng Hao, the head of the Wang family, and the head of the Xue family, all of them could not be spared, and they looked at the area where the Lan Family Medicine Workshop was located one by one, and they were shocked to say, "Can that old guy in Lanchuan refine the Seven Rank Pill?!" Cheng Hao said in shock, and looked at the two family masters Wang and Xue on the side with a heavy face after finishing his words.

In his opinion, if Lan Chuan really broke through at this time, his position in Mucheng would definitely be even stronger, and at that time, it would obviously be more difficult for the three families to join forces to take that Medicine King Ding for themselves.

However, just after he finished speaking, he suddenly closed his mouth, was stunned for a moment, shook his head and said, "Presumably not, if he was able to refine the seven-grade pill, he would have been afraid of the threat of my three families before." ”

Cheng Hao slowly spoke, giving his own inference.

After Cheng Hao finished speaking, the heads of the Wang and Xue families also agreed with each other, and nodded their heads and acquiesced to Cheng Hao's statement. Immediately afterwards, after the three of them looked at each other meaningfully again, they completely regarded the thundercloud as an oolong incident. Even in their opinion, this happened to be a harbinger of the decline of the Lan family

After speculation, the group did not stay long, and after saying goodbye to each other, they recuperated and prepared for the next day's battle.

In the entire Mucheng, only the people of Mushan and Lanchuan Medicine Workshop remained under the scorching sun, and at this moment, it should be said that they were under the rolling black clouds

The thunder kept descending, slashing towards the top of the secret room, and every time the thunder and lightning landed, Lan Chuan's heart retracted tightly, and his heart was extremely worried.

However, after coming down a few times, he saw that the thunder did not slash into the house, but only lingered above the roof for a moment before disappearing, and the heart that hung high in his chest was also slightly lowered.

"Fortunately, this secret room is made of 10,000-year-old Xuantie. Lan Chuan muttered and chatted for comfort, but he didn't dare to relax completely, after all, the thunderclouds above his head had not yet dissipated.

And taking advantage of this opportunity, Mu Shan on the side also immediately opened his mouth and asked the doubts in his heart: "What is the treasure in this secret room? How can it attract a lightning attack?"

When Mu Shan said this, there was still a little curiosity under his serious expression, thinking that there was some mysterious treasure hidden in this secret room.

However, for Mushan's question, Lan Chuan immediately smiled bitterly and said, "Baby, well, it's indeed a baby!"

"I'm really right!" Mu Shan's expression suddenly became exciting: "I said Brother Lan, there is such a treasure, it would be too much to say if you don't let me see it, right?"

"Your niece Qing'er, dare you say you haven't seen it?"

"What?!"

Outside the secret room, Mu Shan stared in astonishment, his face was very strange, and the heart he had just put down hung again, taking care of Lan Qing in the secret room.

At the same time, a very dangerous moment was being experienced in the secret room.

I don't know what kind of material this secret room is made of, Wuchen has not succeeded in attracting the heavenly thunder several times, and I can't help but be a little anxious.

Now the Devouring Demon Worm is in the black hole created by the Great Devouring Determination that it has cast, and it is in a stalemate with itself, and as time goes by, it even faintly has the upper hand!

Therefore, the only thing Wuchen can do at this moment is to attract the heavenly thunder as soon as possible and destroy this demon insect in one fell swoop.

With this thought in his heart, even if he failed many times, Wuchen was not discouraged, but calmed down and prepared for the next performance.

This time, Wuchen used all his strength, except for the soul consciousness used to contain the devouring demon insects, all the rest were sent to the top of the secret room in one fell swoop, and rushed into the thunderclouds above the roof!

And the result of this is also remarkable, a very thick thunderbolt, the thickness of an adult's waist and abdomen, was led down, and it split the top of the secret room made of 10,000-year-old dark iron like a bamboo.

There was a loud click, and the pupils of Lan Chuan Mushan and the others outside the secret room dilated violently, and in the secret room, the dustless in the sea of Lan Qing's soul was also extremely nervous!

"Don't make a mistake"
