This one is hot and one is cold, just like the two heavens of ice and fire.
Fortunately, Lu Feng adapted quickly, so he didn't feel any discomfort at all.
But just because he can endure it, doesn't mean that the organs in his body can tolerate it too.
Especially the blood vessels in the body, as well as the muscles and ligaments in various parts, immediately begin to shrink under this situation of heat and cold.
In this case, the toughness of blood vessels, muscles and ligaments will be greatly improved.
There is no doubt that this kind of martial arts training process will also bring great help to Lu Feng's strength improvement.
…
Time passes minute by minute.
In the blink of an eye, more than two hours had passed since Lu Feng walked into the room.
Nangong Lingyue was waiting outside the living room, gradually becoming anxious.
However, Nangong Lingyue is now wiser and will not go over and disturb Lu Feng easily.
Therefore, she just paced back and forth in the living room anxiously, but did not go near Lu Feng's bedroom door.
After all, it is quite normal for warriors to retreat for several hours at a time.
Nangong Lingyue remembered that when Lu Feng stayed in seclusion at Taro Kato's house, it lasted for one day and one night.
The reason why Nangong Lingyue was a little worried this time was because she was not sure what kind of effect the potion made from the medicinal materials would have.
If the opposite effect occurs, things will be in trouble.
Nangong Lingyue waited for another ten minutes, and then prepared to go to the kitchen to prepare some nutritious food for Lu Feng in advance.
She felt that Lu Feng might need at least a day to retreat this time.
And just when Nangong Lingyue turned around, she suddenly heard a noise behind her.
"Crack!"
The door opened and Lu Feng stepped out.
When Nangong Lingyue looked back, she was immediately shocked by Lu Feng's image at this time.
At this time, Lu Feng was soaked to the skin, his hair was wet, and there was some sweat on his face.
The clothes were soaked and clung to the skin, highlighting the strong muscles on the body and making the body look very tall.
"Lu Feng, what are you doing?"
Nangong Lingyue was a little confused. She looked at Lu Feng at this time, like a drowned rat that had just come out of the water.
But Lu Feng just glanced at Nangong Lingyue and walked directly outside.
Nangong Lingyue felt that Lu Feng was a little abnormal at this time, so he quickly followed him to check the situation.
"Boom!"
Nangong Lingyue had just walked to the back garden with Lu Feng when she heard an extremely loud sound.
"Wow!"
Immediately afterwards, I saw a piece of gravel flying out in front of me, splashing in all directions.
The closest flowers and plants were instantly snapped at the waist, turning into a field of fallen flowers and willows.
Nangong Lingyue couldn't care less about feeling sorry for these flowers and plants, and quickly turned to look at Lu Feng.
I saw that at this time, the rockery stone in front of Lu Feng had been smashed into pieces by Lu Feng.
"Lu Feng, what's wrong with you?"
"How do you feel physically now?"
Nangong Lingyue was worried and shouted to Lu Feng.
But at this time, Lu Feng had no time to answer Nangong Lingyue's question.
Because he himself couldn't tell what state he was in now.
Anyway, I feel that the surging power in my body makes me feel uncomfortable and depressed.
So now his mind is full of thinking about how to release all this power.
In fact, in his state, the best way is to find a warrior who is equal to or stronger than him as a sparring partner.
However, now he and Nangong Lingyue are the only two people in the villa.
As for Nangong Lingyue's little strength, she might not be able to withstand even one move from Lu Feng.
So Lu Feng could only aim at the rockery stones in the yard at this time.
Lu Feng didn't care to talk to Nangong Lingyue, walked to another stone, and slapped it hard with his palm again.
"Crack!"
"Boom!"
This big rock was also broken into pieces in an instant.
Nangong Lingyue's eyes widened, full of shock.
The fact that Lu Feng could break stones with his bare hands was actually not that unusual.
However, the degree of stone fragmentation is also different!
In the past, Lu Feng would easily break the stone with one punch or palm.
But the size of the broken stones is as big as an adult's fist.
But today, Lu Feng slapped it with his palm, and the stone shattered into pieces, only the size of a table tennis ball.
What does this mean?
This shows that Lu Feng's inner strength has become stronger now.
After all, punching a stone until cracks appear and breaking the stone into powder are two completely different concepts.
So after seeing this scene, Nangong Lingyue knew that Lu Feng's current inner strength had improved by more than one level.
In fact, this was exactly the case. Lu Feng himself could feel that his inner strength was indeed much stronger than before.
