"Are you ready?"

"Of course!" Starshift and Nebula nodded heavily.

"Run the dantian of the two of you, attract the Yuan Force in the dantian, and circulate according to the trajectory dredged before, without interruption, I will use this to judge the position of this trajectory in your body, once you faint, the Yuan Force stops running, and I will not be able to find the location of the trajectory, which means that the casting vein has failed." Lin Lao emphasized.

"Don't worry, Grandpa Lin, we will hold on to the end!" Xingyi and the two showed resolute expressions on their faces.

There is no fear at all, Peiyan's two sons are really good seedlings. Lin Lao thought in his heart.

Xingyun and Xingyi sat down, their upper bodies naked, and Lin Lao sat behind the two brothers, putting his two hands behind their backs.

The nebula and star-shifting dantian were spinning faster and faster, and the wisps of yuan force that rushed out of them continued to flow according to that specific trajectory.

In Lin Lao's body, the dantian also began to circulate at an accelerated pace, wisps of golden yuan power flowed out of his dantian, and the five major meridians were three purple and two blue, and no one noticed that Lin Lao was actually a metallic third-level martial artist.

The golden yuan force in Lin Lao's body ran to his hands, and from above his hands, it flowed into Xingyi and Xingyun's bodies, and the golden yuan power did not rage in the two people's bodies, but ran around the trajectory of the flow of the two people's yuan power, as if they were watching from the sidelines.

Xingyi and Nebula used the internal Yuan Force to run on that trajectory about ten times, and the metallic Yuan Force next to them became agitated, and wisps of sharp killing qi leaked from it, as if it could cut off all obstacles in the world.

The two metallic Yuan Force, respectively, approached an ordinary meridian close to the two dantians, and the metallic Yuan Force turned into two scissors, flashing at the place of the meridian, and the meridian was immediately cut off, and at the same time, a soft metallic Yuan Force wrapped around the broken meridian, slowly repairing.

Xingyi and Xingyun spat out mouthfuls of blood at the same time, and a sharp pain came from their bodies, but the two gritted their teeth and did not stop the operation of Yuan Li.

The scissors of the metallic Yuan Force Transformation stared at another meridian, and in the same flash, the second meridian was also cut off, and the broken meridian was also wrapped in a soft Yuan Force, and it was slowly repaired.

Another mouthful of blood spurted out of the two Nebula's mouths, and both of them turned a little pale, and the sharp pain almost made them unconscious, but they both had a sentence in their hearts at the moment, "Hold on!"

The golden scissors didn't mean to stop, and cut three more times in succession, and the three meridians were immediately broken, and a small section of the meridians was cut off from each.

Xingyun and Xingyi vomited several mouthfuls of blood one after another, and there was no trace of blood on their faces, and their already fair skin was a little pale as paper at the moment.

After cutting the five meridians, the golden scissors gradually dissipated, and at the same time, two more metallic Yuan forces entered the two of them, and the two Yuan forces transformed into a golden palm, and the five cut meridians came to the trajectory of the Xingqi and Nebula Yuan Forces.

The golden palm neatly placed the five meridians on the trajectory, and then the golden palm dissipated, turning into six soft metallic yuan forces, wrapped in the six fractures between the dantian and the meridians, between the meridians and the meridians, and between the meridians and the lifegate acupoints.

The golden yuan power continued to rush out of Lin Lao's dantian, entering the Xingyi and Xingyun bodies, and replenishing into the six fractures.

A little fine beads of sweat gradually appeared on Lin Lao's forehead, obviously this kind of yuan power output consumed Lin Lao a lot, and a wisp of blood gradually appeared on the faces of Xingyi and Xingyun in front of him, but the pain when the meridians were connected was more intense than when the meridians were cut.

Xingyi and Xingyun's foreheads kept shaking, and beads of sweat dripped from their foreheads, and wisps of pain appeared on their faces, but they were still gritting their teeth and holding on.

Time, spent in the efforts of the three of them, unconsciously, has come from night to day.

Lin Lao withdrew his hands behind Xingyun and Xingyi, put his hands together on the dantian, and the aura of the surrounding heaven and earth quickly headed towards Lin Laohui, and after a while, Lin Lao opened his eyes, no longer continued to absorb the aura, but stepped forward to inspect the situation of Xingyun and the two.

The Yuan Force in the bodies of the two of them was still running according to that trajectory, and they didn't even know that they had completed the casting vein at this time?

"Nebula, Xingyi, okay, you can take back the Yuan Force. Lin Lao whispered in the ears of the two, and the two seemed to hear Lin Lao's words, and immediately opened their eyes, but before they could say anything in a hurry, they fainted.

"I still underestimated these two children, their willpower is far more terrible than I thought, they have been running the Yuan Force all night, the Yuan Force in their dantian is afraid that it is also on the verge of exhaustion, even if they lose consciousness, but the instinct is still insisting on running the Yuan Force, this kind of will, he will be able to achieve a great cause one day. Lin Lao thought to himself.

When Nebula and Starshift woke up, it was already early the next morning.

During the day and night when the two of them were unconscious, Lin Lao never left this room, while exhaling the aura of heaven and earth to supplement his own needs, he used Yuan Li to repair the damaged meridians in the two of Xingyi's bodies and strengthen the six fractures of the sixth meridian.

After Xingyi and Xingyun woke up, they saw Lin Lao standing beside the bed for the first time.

"Wake up, you two have slept for a day and a night, how do you feel now?" Lin Lao asked.

"I feel, how do I feel weak, and I can't exert my Yuan Force. Xingyi asked suspiciously, and Xingyun also had a puzzled expression on his face.

"Two news, one good and one bad, which one to listen to first?" Lin Lao became naughty and deliberately sold off.

"Listen first!" replied Xingyi and Nebula.

"Okay, it's that your step of casting the veins has been successful, I don't believe the two of you take a look inward, and look at the sixth meridian between the dantian and the life gate acupoint. Lin Lao said with a smile.

"Really, really, we made it, brother!" Nebula exclaimed happily.

Between the dantian of the two of them and the lifegate acupoint, there is a golden meridian connected.

"What about the bad news? Grandpa Lin. Xingyi asked.

"The bad news is that the meridians of the two of you are seriously damaged, and the newly cast sixth meridian is also very fragile, and the breakpoint on it has not completely disappeared, and it cannot withstand the impact of the aura of heaven and earth. ”

"Therefore, I sealed the dantian of the two of you, and I could neither exert my Yuan Power nor communicate with the aura of heaven and earth. Lin Lao said with a smile.

"Ah, then how have we spent the past half a year, and how are we going to cultivate!" A wisp of bitterness appeared on the faces of Xingyi and Xingyun.

"It's not that you can't cultivate, you can just take this opportunity to temper your physical body and strengthen your physical strength, which will be of great benefit to your cultivation in the future!" Lin Lao comforted.

"The golden meridians, why are they golden, shouldn't they be the same as the five major meridians, white or red?" Lin Lao was also a little puzzled, and there was no record on the parchment scroll.
