In this way, Su Yu introduced the impact of the waterfall pouring down to quench one meridian after another, although the speed was very slow, and the meridians that were tempered each time were very limited, but the harvest was huge.

In two hours, only four meridians have been refined, and the destructive power of the impact is very strong, and the meridian refining is a very dangerous thing, Su Yu does not dare to have the slightest support, so he can only refine the meridians little by little.

Su Yu completed a tempering of the meridians of the whole body in three days, and the impact force on the edge of the waterfall was completely able to adapt, and after the meridians of the whole body were tempered by an impact force, the impact force here no longer had much effect.

Su Yu can take a step further towards the center of the waterfall, the strength of his meridians has been greatly improved in three days, the strength of his current punch is very different from before, if he uses spiritual power, the power is at least twice as much as before!

The speed of introducing aura when breathing and exhaling also increased a lot, and the cyclone in the dantian looked like it had increased a lot, and it was already one-fifth of the entire dantian.

At this speed, it shouldn't take long to step into spiritual adversity, but I don't know how long it will take for the acquired spiritual power in his body to be converted into innate spiritual power, according to the experience of his predecessors, it seems that it can take three months at every turn, and two months at a time, but fortunately, Su Yu has a hundred-year-old Poria cocos in his hand, compared to ordinary people, Su Yu's conversion speed of spiritual power can be shortened a lot.

"It's time to take a dip in the middle of the falls. Su Yu looked at the waterfall pouring down, and now the impact on the edge of the waterfall has no great effect on the meridian quenching.

Su Yu stepped towards the center of the waterfall, and the impact of the waterfall suddenly increased, almost pushing Su Yu out of the waterfall again.

Su Yu gritted his teeth to withstand the impact and gradually adapted to the new position, but the impact of the waterfall still prevailed, washing Su Yu into the current.

Su Yu exhaled, only then did he push forward a little, and he couldn't hold on for long, if he was placed in the center of the waterfall, I am afraid that the impact there could directly push Su Yu out of the internal injury!

Walking out of the current, Su Yu was not in a hurry to rush up again, because he heard someone calling him.

"Idiot, it turns out that you have been here all these days!" The person who spoke out was naturally Han Shixuan, she dared to go to Tangmen Xiaofeng during the day, Su Yu was very surprised.

"Xiaoxuan, why are you here, it's not night. Su Yu looked at the sky, it was noon, didn't Han Shixuan dare to come out only at night?

"I'm here to play with you!" Han Shixuan grinned sweetly, and found a random mountain rock to sit down.

"Aren't you afraid of being discovered by the elders of the Tang Sect? The elders of the Tang Sect are all powerful. Su Yu looked around and was a little relieved to see that there was no talent.

"Hey, it's okay, they won't find out!" Han Shixuan smiled slyly, the things that her grandfather gave her were easy to use, so that they would not be discovered by the elders of the Tang Sect.

Su Yu had already walked out of the water, ** on his upper body, there were still some water droplets hanging on his body, and his small body was a little copper in the sun.

"Idiot, what are you practicing here?" Han Shixuan asked curiously, as soon as she found Su Yu's figure, she saw Su Yu standing under the waterfall, and was washed down by the waterfall.

"I'm exercising my body, refining my meridians with the impact of the waterfall. Su Yu also found a mountain stone next to Han Shixuan and sat down, looking at the pouring waterfall, when he could stand in the middle of the waterfall and withstand the impact of the waterfall!

"Use the impact to refine the meridians?" Han Shixuan's eyes widened, this method is too extreme! Directly refining the meridians is not a joke, the slightest mistake will become a waste!

"I've already refined it. Looking at Han Shixuan's suddenly widening eyes, Su Yu said calmly.

Han Shixuan's eyes widened, Su Yu had already successfully tempered it, but thinking about the image calculated by his grandfather, he was relieved, and it was estimated that Su Yu alone in this world could directly use impact power to refine the meridians.

"Idiot, what strength do you have now?" Han Shixuan supported her knees with her hands, held her face, tilted her head and asked Su Yu.

"Spiritual Realm. Su Yu replied.

"Spirit Realm ......" Han Shixuan muttered, then counted what was with her fingers, then sat in place and looked at Su Yu and smirked.

"Is there any problem?" Su Yu felt that Han Shixuan was smiling inexplicably, and touched the back of her head, is the spirit realm funny?

"It's okay, it's okay, you can continue to refine!" Han Shixuan beckoned, laughed again, and her eyes were bent into crescent moons.

Su Yu really felt strange now, could it be that there was something strange on his face? He looked down at the water, obviously it was the same as usual, there was nothing!

Su Yu shook his head, how could the girl's mind be something he could guess, expel this strange feeling in his heart, he still continued to adapt to the impact of the waterfall!

Han Shixuan just sat in place and watched Su Yu step on the waterfall again and again, and be washed down by the waterfall again and again.

Seeing Su Yu's somewhat embarrassed appearance, Han Shixuan covered her mouth and snickered, and it didn't take long for Han Shixuan to stop laughing, because Su Yu had been able to stand firm under the waterfall for a while.

Su Yu was not in a hurry to immediately introduce the impact into the meridians, his own body was not able to fully withstand the impact, he was adapting to the current environment.

"Boom!"

Another waterfall poured down, and a heavy impact hit Su Yu, and Su Yu was once again rushed out by this force.

Su Yu calculated, he probably didn't hold on to a stick of incense just now, and it would probably take some time to fully adapt to the impact of this place.

In fact, Su Yu can completely withstand the use of spiritual power, but he now needs to exercise the bearing strength of his physical body, and even more importantly, he needs to introduce the impact of the waterfall to refine the meridians, and only by removing the protection of spiritual power can every part of his body be refined!

"Nerd, come on!" Han Shixuan looked at Su Yu, who was washed down by the waterfall again, and opened her crystal eyes to cheer for Su Yu.

Han Shixuan knew that Su Yu was not discouraged, but she still puffed up at Su Yu, holding her cheeks with both hands and staring straight at Su Yu's back.

"This nerd's perseverance is really amazing, I'm afraid other people can't hold on!" Han Shixuan whispered to herself, the hardships in this are not something that ordinary people can bear, and they can't be protected by spiritual power, so they can only adapt to the impact of the waterfall again and again.

And the method of refining the meridians with impact force doesn't know how Su Yu came up with it, this is a way to cultivate, but it is always dangerous for the sword to go sideways.

In the following days, Su Yu would repeat the same action every day, withstand the impact, introduce the impact to quench the meridians, and re-adapt and re-temper the quenching again and again in a place a little further from the center of the waterfall.

Han Shixuan climbed to the top of Xiaofeng on time every day, sat on the side and watched Su Yu exercise, sometimes seeing Su Yu refining the meridians in his body with impact force, and when he stood motionless under the waterfall, he would also meditate in place to breathe and breathe, and practice for a while.

In the blink of an eye, more than half a month has passed, Su Yu is now only one step away from the center of the waterfall, and the impact in other ranges, Su Yu is now fully able to adapt, and the meridians in his body are several times stronger than half a month ago, because of the exercise of the impact of the waterfall, the resistance of Su Yu's entire body has also improved a lot.

** The half of the body is more explosive than half a month ago, and the temperament of the whole person has become a lot calmer.

During the day, he tempered the meridians under the waterfall, and at night, he breathed in and inhaled the spiritual energy, and the cyclone in the dantian was only slightly overflowing, but Su Yu compressed this cyclone again, and the dantian that was about to fill up was empty again.

Su Yu knew that at the beginning of cultivation, the foundation was the most important, the improvement of strength was important, but a solid foundation was even more important, spiritual adversity was a watershed in cultivation, after the acquired spiritual power was transformed into innate spiritual power, there would be a big reversal in strength, and the original five-fold spiritual power would suddenly increase to twenty times!

Su Yu compressed and compressed the cyclone in his body, and accumulated thick and thin, so as not to make the foundation unstable.

"Idiot, are you going to step into the center of the waterfall today?" After watching for more than half a month, Han Shixuan already had a clear understanding of Su Yu's habits, and whenever he completely adapted to the impact under the waterfall, he would definitely take another step in the center of the waterfall the next day!

"Well, as long as I can withstand the impact of the waterfall center, this tempering will be considered complete!" Su Yu's eyes were a little fiery when he looked at the waterfall center, as early as half a month ago, Su Yu was very much looking forward to the waterfall center.

The impact of the center of the waterfall is the largest, and it is also the last step of tempering for half a month, and the impact of the center of the waterfall is ten times that of the outside!

And those elixirs that Su Yu collected were also used at this moment, which was the most dangerous step!

When you arrive at the center of the waterfall, after bearing the impact of the center, the impact force introduced can no longer be introduced like the edge of the waterfall, and all the meridians of the body must be completely released at the same moment, and the impact force of the center of the waterfall should be introduced at the same time!

And what will happen if the impact force is introduced to impact the meridians at the same time, Su Yu can't say well, He Mingyuan helped Su Yu refine the elixir collected into a senior brother in the Medicine Pavilion, and this pill is now in Su Yu's mouth.

Because it was very painful at the moment when the meridians of Su Yu's whole body were introduced at the same time, at that moment, this pill must be swallowed, otherwise, the sudden huge impact force would hit the meridians in Su Yu's body fiercely, and the consequences of the rupture of the meridians were absolutely possible!

Although Su Yu has been refining his meridians little by little for more than half a month, the results of most of the past half a month are all foreshadowing for this last moment, and the last step is the key!
