After hearing Master Yu's order, Qin Sang didn't dare to hesitate, hurriedly opened his mouth, swallowed the dragon ball, and then immediately sat cross-legged and calmed down.

When the dragon ball entered his abdomen, a crimson glow appeared on Qin Sang's body, and the whole person was like a boiled prawn, and the flesh and blood all over his body turned red, exuding a blazing high temperature, causing the air in the cave to become a little scorching.

As time passed, the red light on his body became more and more abundant, and the air in the cave was a little curled due to the high temperature.

The facial features on Qin Sang's face gradually began to distort, as if he was enduring unimaginable pain, the large beads of sweat on his forehead gathered into a river, sweat fell like rain, and the ground was wet.

Master Yu has been watching coldly from the sidelines, and he has no intention of interfering.

The pain in Qin Sang's body became more and more intense, and his body even began to swing like a swing, and it was almost difficult to maintain a posture of staggering, but he always closed his eyes, gritted his teeth, and persevered.

'Bang!'

There was a muffled snort, and then there was an explosion on Qin Sang's arm, the skin and flesh opened, and when he looked closely, the meridians were cracked, and a red light flashed, and the medicinal power of Danlong ginseng was like a long rainbow, spilling out.

At the same time, black impurities began to ooze from the surface of Qin Sang's body, but they were immediately scorched by the high temperature and cemented on his body.

Master Yu stretched out his hand at this time, held the medicinal power in the palm of his hand, refined the impurities contaminated in it, and then took out a bottle of spiritual liquid, and hit a drop and fell to Qin Sang's wound, and the wound recovered at a speed visible to the naked eye.

For the disciples in the Qi refining period, the medicinal power of Danlong ginseng is still too violent, and it is normal to take a little bit of green liquid, slowly refining, easy to cut the marrow, remove impurities in the body, and improve qualifications, until they adapt to the medicinal power of Danlong ginseng, they can take that dragon ball and try to break the threshold.

But the Yuanying Patriarch was in a hurry, and Master Yu didn't dare to be careless, so he simply refined the entire elixir and gave it to Qin Sang in one go, and even he could cultivate it, couldn't he bear this little pain?

And with his personal support, there will definitely be no mistakes.

Immediately afterward, I heard a 'bang bang' sound.

Qin Sang was almost full of holes on his body, but Master Yu was able to make a timely move every time, and almost consumed most of the bottles of healing elixir, which helped Qin Sang get through this difficulty.

It's just that Qin Sang suffered, and he felt like he was thrown into the furnace, and the flesh and bone marrow in his body seemed to be scraped open by a sharp knife, and then calcined with a blazing fire, from beginning to end, from the inside to the outside, he was roasted on the outside and on the inside.

Only the coolness of the spiritual fluid when it landed on his body every time he could take a breath.

Hang on!

The only chance in this life, if he gives up halfway because he can't bear the pain, he won't forgive himself!

Finally, no new impurities precipitated out of Qin Sang's body, the red light went from prosperity to decline, introverted into the body, and gradually dimmed, and when it was about to disappear, Master Yu injected the medicinal power confined in the palm of his hand into Qin Sang's body, and continued to repeat the previous process.

Maybe it was numbness, Qin Sang was able to be expressionless in the back, but every time the meridians were broken, his body would tremble, and the amplitude would become smaller and smaller.

In the end, Qin Sang's body completely stabilized, and his breathing gradually slowed down, just like his usual cultivation state.

Master Yu suddenly flashed to Qin Sang's side, spilled out some of the remaining spiritual liquid, and used spiritual power to hit all parts of Qin Sang's body, helping his medicinal power to dissolve, so that the hidden injuries in his body could be completely recovered.

Seeing that Qin Sang's state had truly stabilized, Master Yu nodded, silently pushed open the door of the cave, and walked out.

Turning around and looking at the cave mansion, a look of envy suddenly appeared on the face of Master Yu, not to Qin Sang, but to Ma Beizhen.

In the end, it is still good to have a backer, even if the furnace is broken, there can be a Yuanying patriarch to give Danlong ginseng to him, the head of the family.

Master Yu was saddened and left.

......

After January.

The cave mansion, which had been silent for a whole month, suddenly sounded a hehe laughter, which was a bit infiltrating, and it looked particularly weird in the dark cave mansion.

Then the laughter grew louder and louder, turning into laughter and wild laughter.

The people in the cave seemed to be crazy, laughing out of breath, laughing tears and snot flying together, laughing bent over and couldn't stand up straight, before they stopped coughing.

There was a sound of soo.

The night pearl illuminated the cave, and Qin Sang got up from the ground and changed into a brand-new robe, his eyes were unusually bright.

Finally.

The foundation has been built!

Qin Sang looked at himself inwardly, and the changes in the sea of qi were the most obvious, the original gaseous spiritual power began to become viscous in the process of breakthrough, until the moment of successful breakthrough, it was completely liquefied.

Then Qin Sang turned into a black hole, and the spiritual power in the cave mansion was frantically infused into his body, and in the best cave mansion in Shaohua Mountain, the spiritual power continued to flow until the sea of qi was filled again, and Qin Sang gave up.

At this time, the spiritual power in his body, both in quantity and quality, was much stronger than during the Qi Refining Period, which could be said to be a world of difference.

Another change is that the Yuan Shen is more condensed and the Divine Consciousness is stronger, not only the sensing range is several times larger than that of the Qi Refining Period, but also the Divine Consciousness can be separated from the body without entrusting other objects, and when encountering weaker prohibitions, it can be forcibly broken with the Divine Sense.

There is no need to use the Qi Hope Technique clumsily like during the Qi Refining Period, just by sweeping the Divine Sense, you can find the fluctuations of the spiritual power on the other party's body and see the other party's cultivation.

In short, it is very useful.

"Come out!"

Qin Sang let out a low snort, a black light flashed, and the ebony sword hovered in front of him, trembling slightly, as if congratulating his master on successfully breaking the threshold.

Qin Sang was in a good mood and urged, only to see a green light flash, and the ebony sword flew in the void, and finally turned into an emerald green lotus, which dissipated after a long time.

With this action, only a small part of the spiritual power in his sea of qi was consumed, and it was still full, so he didn't have to be so careful in the future, worrying about the consumption of sword qi.

It's just that his attainments in kendo are not high enough, and he can't do sword qi rainbow and sword flying.

After a hard handful, Qin Sang calmed down the excitement in his heart.

After regaining his composure, Qin Sang had to return to reality, the smile on his face and the excitement in his eyes were all reined in, everything was in exchange for what he promised to be a furnace.

After taking the benefits of the master's advanced cultivation, there is no possibility of defaulting on the debt, not only to do it, but also to do it well, so that they are satisfied.

Qin Sang was not in a hurry to inform the head of the sect that he had built a foundation, and after a short rest, he began to cultivate, only the last step was needed, the jade tripod was formed, the jade liquid was full, and the exercises were refined.

He was also mentally prepared to be the furnace for a long time.

......

The main hall of the head of the peak.

Master Yu was discussing the affairs of the sect with several stewards during the foundation building period, and suddenly a transmission note flew into the main hall, and after seeing it, Master Yu showed joy on his face, and ordered everyone to act cheaply, so the sword flew out of the hall and went straight to Shaohua Mountain.
