When more than a dozen members of the Hidden Dragon Clan rushed to the vicinity of the wolf seal, the wolf seal, which suddenly became larger, directly sucked everyone in.

In the wolf seal, there is a huge space.

However, it was pitch black inside, and even the fingers could not be reached.

And in the center of this pitch-black place, there is a circular grinding disc that emits a faint light.

There is no doubt that this circular grinding disc is the internal qi grinding disc that Tang Fei said.

"Let's get ready. ”

At this time, Tang Fei's voice came from the air.

Immediately, a strong internal qi spread around Tang Fei's body.

This internal qi soon tended to materialize, and it slammed towards the internal qi grinding disc.

When the rich internal qi collided with the internal qi grinding disc, the internal qi grinding disc, which was originally only emitting a faint light, suddenly shone brightly!

In the darkness, the light suddenly became stronger, piercing everyone's eyes

With that, a powerful force poured into everyone's bodies and converged to the position of the dantian.

This powerful force suddenly began to crush and grind the essence of the internal qi in everyone's body in a domineering manner.

At first, there was only a slight ache in the face.

This slight pain begins to gradually become intense.

Because, the force of the grinding is slight, so the pain is also mild.

However, the grinding power is increasing dramatically in a geometric multiplier.

Soon, the pain reaches the limit that the human body cannot bear.

Among the members of the Hidden Dragon Clan, someone soon let out a cry of pain.

"Everyone sat down, gathered their minds, and tried to resist the pain. ”

Tang Fei said this, but he couldn't help but sigh in his heart.

Although the pain is very intense now, this pain is actually only the beginning.

When everyone heard this, they sat on the ground one by one, and began to work hard to get rid of the distractions in their hearts and try to condense their minds.

Although the original pain is bound to be more obvious if you concentrate your mind on resisting pain, your ability to resist pain will also increase.

However, as time went on, the unbearable pain began to slowly exceed the limits of the human body.

The materialized internal qi is ground into pieces piece by piece, and the pain in it is like an internal qi grinding disc grinding the flesh and bones in the body.

The pain can be imagined.

At this moment, everyone finally knew why Tang Fei had a strange expression on his face when he talked about this cultivation method just now.

Of course, for martial artists, especially for martial artists who have reached the peak of the Hidden Dragon Clan, it is already extremely difficult to improve their strength, so even if they have to endure great pain, as long as they can improve their strength, it is very tempting.

But soon, under the crushing of the internal qi grinding disc, even the members of the Hidden Dragon Clan began to make painful noises because of the severe pain.

"Boss, what the hell is this, my brother is about to lose it. ”

Although the strength of the fast knife is the strongest, at this time the other party has become the first person who can't stand it.

Tang Fei didn't expect this to be the result, and while also suffering great pain, he gritted his teeth and said: "If you want to improve your strength, just insist, of course, if anyone wants to give up, I won't stop you." ”

While speaking, Tang Fei couldn't help but take a deep breath, the expression on his face was slightly distorted, and he couldn't blame the fast knife for not being able to hold on, after all, when he used the internal qi grinding disc for the first time, he also had the urge to give up because he couldn't bear it.

Of course, as the backbone of the Hidden Dragon Clan, Kuaidao didn't actually want to give up, he just vented, and soon continued to grit his teeth and persist.

Ten minutes passed.

The grinding of the internal gas by the internal gas grinding disc has been completed.

The internal qi of the essence is crushed and fragmented, and finally it tends to be substantiated again.

And the great pain that happened to the members of the Hidden Dragon Clan has finally come to an end.

Ten minutes was as long as a century for the members of the Hidden Dragon Clan.

Soon, everyone's faces, which had become distorted by pain, slowly calmed down.

Immediately afterward, ecstatic expressions appeared on everyone's faces.

Because, they all clearly perceived that the crushed internal qi soon began to aggregate again, and tended to be substantial.

Moreover, it seems that after being crushed just now, some impurities and dross in the original internal qi have also been crushed out.

The internal qi that has re-tended to be substantiated is not only purer than before, but also more tenacious.

At the same time, everyone also clearly perceived that their perception of the things around them had also improved significantly.

This feeling is as if he has just been promoted from an ordinary person to a martial artist, and he has just gone from a state without any internal qi to an internal qi at the beginning.

It is conceivable that the strength of everyone must have made great progress.

The quick knife volleyed a punch, and a surprised smile appeared on his face, and his strength and speed had obviously improved very much.

The rest of the people also sensed their own strength, like a quick knife, and their faces also showed excited expressions.

"How?"

Tang Fei took a deep breath and said with a smile.

Everyone looked at each other, and they all sighed with emotion, and it seemed that the pain just now was not in vain.

However, Tang Fei's next words made everyone's hearts sink.

"Now, everyone has only passed the first step of the internal qi grinding plate, and if you want to become a real master, you need to go through a total of ten tests, and the pain will be stronger and stronger each time, and the time will be longer and longer.

All of a sudden, everyone wanted to cry.

It's just that without waiting for everyone to react, the severe pain swept in again, as Tang Fei said, this time the pain was even more menacing than the last time.

The pain was so severe that everyone trembled.

Even, some people couldn't help but scream.

As Tang Fei said, this time, the whole process lasted longer, and the pain was more intense.

After a full half hour, the materialized internal qi in everyone's bodies was ground again, and then became substantial again.

And after this time, everyone has a heartfelt fear in their hearts, and the whole thing seems to have become prostration, and they don't want to bear the pain for a second for the kind of pain before.

However, when they thought that according to Tang Fei, all this was just the beginning, and after they had to endure this kind of pain ten times before their strength could be substantially improved, everyone was already crying without tears.
