This wooden house is the best place to practice internal strength, and Lu Fan felt that if he could study the construction structure of this wooden house, he would build it himself after returning to Nancheng.

At that time, everyone under his command will come in to improve their internal strength, then the speed of cultivation will be greatly improved, and Lu Fan's revenge power will increase rapidly.

And Lu Fan and his senior sister Xie Xiaoluo, masters who have reached a certain level of cultivation, can also use this wooden house to continuously improve their cultivation, as long as they enter the wooden house, control their internal strength and do not increase their resistance.

In order to improve his martial arts cultivation in a short period of time, Lu Fan quietly adjusted his internal strength to about one layer, and at this time, Lu Fan was obviously a little struggling and screamed in the wooden house.

The red-robed envoy outside felt a little strange when he saw Lu Fan's screams getting louder and louder.

"What's going on? I didn't increase the pressure, this kid's internal strength should have gradually increased a lot, but why did he keep screaming from his mouth, and it seemed to be screaming more than before. The red-robed envoy muttered to himself, not understanding.

After another minute or two, Lu Fan's screams still did not decrease significantly, and the red-robed envoy couldn't sit still at this moment.

Although this red-robed envoy could stand by and watch Lu Fan in great pain, as long as Lu Fan didn't stop begging for mercy, even if there was any accident, even if Lu Fan died, the red-robed envoy would not have to be responsible.

But this situation has never been seen by the red-robed envoy, and even if some people who are not talented enough can bear it, they will beg for mercy and stop at a critical moment.

Now, judging from Lu Fan's screams, Lu Fan obviously couldn't bear it anymore, but he didn't shout to stop or beg for mercy, which made the red-robed envoy a little anxious and entangled.

"Boy, what the hell is going on with you? Didn't you scream very little just now? At this time, you should get used to it, how can you suddenly scream! Are you really not good? If you really can't stand it, beg for mercy immediately and stop it, I'll turn off the switch! The red-robed envoy reminded Lu Fan.

The red-robed envoy still had a good feeling for Lu Fan, and he had an obvious good impression. He felt that Lu Fang should be a martial artist with good talent, and he didn't want Lu Fan to die like this.

"Ah......" Lu Fan did not reply to the words of the red-robed messenger, and the screams in his mouth continued.

The red-robed envoy couldn't wait any longer, he immediately walked to the side of the wooden house to turn off the switch, and it was at this time that Lu Fan finally spoke.

"Don't turn it off, I can still stand it!" Lu Fan said.

Hearing this, the red-robed messenger immediately stopped.

"Boy, what the hell is going on with you? Our machines are rigorously built to make no mistakes! The red-robed messenger wondered.

Lu Fan knew that the red-robed messenger was very puzzled, but he was not in the mood to explain to the red envelope messenger.

Just now, Lu Fan used about one percent of his internal force, and it took a long time to resist the fluctuations and oppression of the air flow in the wooden house, and now Lu Fan's internal force has greatly improved.

This is this kind of pain is really unacceptable, even this kind of master can only grit his teeth and stick to it with his will.

"How long have I been holding on now, and what are the results?" Lu Fan asked.

After the red-robed envoy heard this, he immediately took out his stopwatch, and he found that Lu Fan had been holding out for two hours now.

"You've been holding out for two hours now, but depending on the pressure control, you're almost equal to two days!" The messenger in the red robe said,

"Please help me turn the pressure switch to a mode where one hour equals one week!" Lu Fan said.

Hearing this, the red-robed envoy frowned, and he felt that Lu Fan was not looking for death?!

"What are you kidding, you can't give up your life to save time!" The red-robed messenger reminded.

Lu Fan replied: "Don't worry, I won't give away my life, if not, I will stop immediately!" ”

Although the red-robed envoy heard Lu Fan say this, he still had to remind Lu Fan.

"You have to think clearly, I can do what you ask, but if you are in this situation now, your grades will not be bad. But if you take a risk, you might end up with bad grades! The red-robed messenger persuaded.

The red-robed envoy said this, not only because he had a good impression of Lu Fan. It's more that the red-robed envoy doesn't want to organize the loss of a talented talent.

"I believe in my strength, please start!" Lu Fan said.

After saying this, Lu Fan increased his internal strength to about fifty percent, because he didn't want to waste any more time, he had to hurry up and meet the controlling figure overlord at the core of this organization.

The red-robed envoy saw that Lu Fan had already decided, so he had no choice but to do what Lu Fan wanted.

"Boy, I hope you can hold back!" After saying this, the red-robed messenger turned up the pressure.

Immediately, Lu Fan felt that the airflow fluctuations in the room were getting stronger and stronger, although he had adjusted his internal strength to fifty percent at this moment, he could still clearly feel some discomfort on his body.

"This wooden house is not very suitable for cultivating internal strength, I must find an opportunity to learn the secrets of the construction of this wooden house!" Lu Fan said to himself in his heart.

In the past, Lu Fan was still very puzzled, apart from the four major sects today, which organization could have such a powerful force and could destroy the Holy Heavenly Sect overnight!

Now Lu Fan finally understands that it is because this organization has the most high-tech training method that it can cultivate a large number of martial arts masters in a short period of time, and this kind of strength is not possessed by the four major sects today.

After a few hours, Lu Fan finally walked out of the wooden house.

With Lu Fan's martial arts cultivation, he could continue to stay in this wooden house for a long time, but now he was no longer necessary.

After all, Lu Fan didn't really come here to improve his martial arts cultivation, mainly to find out the last murderer of the sect's destruction.

"Congratulations, I didn't expect your kid's talent to be so powerful, I'll go report to the overlord now and let the overlord meet you!" The red-robed messenger was pleasantly surprised.

As soon as Lu Fan heard this, he would immediately see the core boss of this organization, and his face was very excited and happy.

"Thank you!" Lu Fan thanked.

The red-robed envoy felt that Lu Fan was so excited and happy because he could see that the overlord would be reused, how could he know that Lu Fan was going to find out the murderer behind the Holy Heaven Sect.

"Boy, stay here, I'll come when I go!" The red-robed messenger commanded.

"Yes!" Lu Fan replied.

Looking at the back of the red-robed envoy, Lu Fan was extremely excited in his heart.

That's great! As long as you see this overlord, you should know who the last murderer of the Holy Heavenly Sect is! Lu Fan was both nervous and excited.

Lu Fan was nervous because he was afraid that if this overlord knew him, Lu Fan would be in danger!

He knew that there must be a large number of martial arts masters in this place, and although Lu Fan's martial arts were strong, he might not be able to escape successfully.
