"Snort!" A sword qi drew a bloody mark on Lin Xuan's hand, and the red blood flowed out, Lin Xuan held the black crystal of the cheetah in the bleeding hand, and the black crystal bloomed with a little deep black light, and after a while, the black crystal turned into a streamer and entered Lin Xuan's body......

Lin Xuan clenched his hands and took a deep breath, the blood transformed by the black crystal quickly flowed towards Lin Xuan's heart, and it continued to rotate next to a gray-black crystal in Lin Xuan's heart......

"Drink!" Lin Xuan shouted, the source qi brought by the blood crystal flowed rapidly throughout his body, and the blood transformed by the black crystal began to rotate wildly on the surface of Lin Xuan's own blood crystal, and every time it rotated, the blood would be a little less...... If Lin Xuan had noticed his source core now, he would have found that the source core light at this moment was extremely dim, and all the source qi that had been cultivated by the source core had shrunk into the source core......

I don't know how long it took, maybe a few hours, maybe a day or two, Lin Xuan felt that he had lost the concept of time in the outside world, and when the last drop of black blood merged into the black crystal, Lin Xuan suddenly opened his eyes, and a crazy killing intent swept out......

"Buzzing ......" vibrations pierced out of Lin Xuan's body, and turned into energy waves like substance, shaking the cave to drop a lot of earth and rocks, but fortunately, there was not much energy contained in this energy wave, so it was not a big deal......

"No, no......" Dao Yuan kept turning around Lin Xuan and muttered to himself: "The murderous aura is so heavy, do you really want to comprehend the Killing Heavenly Dao?" Lin Xuan originally comprehended a little bit of the Good Heavenly Dao, it stands to reason that there will not be such a pure Killing Dao and the Good Heavenly Dao coexisting......

"Hum!" It seemed that Lin Xuan's murderous aura that was constantly revealing had triggered the Great Dao of Heaven and Earth, and a wave of mysterious fluctuations enveloped Lin Xuan's body, Lin Xuan closed his eyes again, carefully comprehending this fluctuation......

"Killing Sword Dao, it turned out to be Killing Sword Dao!" Dogen's expression didn't know whether he was happy or worried: "This doesn't quite match the Great Dao of Panic, right...... Lin Xuan had better comprehend the way of the sword itself, but he didn't expect that he would first comprehend the way of the sword of killing due to the cultivation of blood crystals, although the way of the sword is the main killing, but killing is not the whole of the way of the sword...... Wouldn't it be bad for him to be so radical in the future?"

As time continued to pass, a gray momentum rose up in Lin Xuan's body, and in the blink of an eye, it gathered into a slender sword shape above Lin Xuan's head...... Lin Xuan jumped up suddenly, picked up the long sword that gathered momentum, and danced wildly in the cave......

"Boom, boom, boom......" A series of violent explosions rang out in the cave, and after a while, from the outside, the hill appeared to protrude left and right, constantly spewing out some stones, and the water of the waterfall was cut off from time to time, and then recovered, and then was cut off, and then recovered......

......The overwhelmed cave finally collapsed, and the entrance to the cave was covered with stones.

"Boom......" A figure rushed out of the hole and fell into the pool with a thud......

"Poof......" Lin Xuan leaked his head out of the pool, this small water tank is not deep, and it only reaches Lin Xuan's neck when it stands upright, the water in the pool is crystal clear, extremely cool, Lin Xuan spit out a mouthful of water, shook his head, jumped up from under the water, and landed on the ground by the water......

Dried the soaked clothes on his body directly with source qi, shook his head, shook his arms, stretched his waist widely, and made a crackling sound on his body......

"Dao Yuan, how long did it take me to break through this time?" Lin Xuan sat on the ground, his eyes a little empty, and asked casually.

"It's not much, it's just a day!" Dogen said casually.

"Oh......" Lin Xuan lowered his head and rubbed the grass under his buttocks.

"I comprehended the Heavenly Dao, and I also used a Heavenly Dao, how do you feel......" Dao Yuan learned from Lin Xuan's appearance, leaning on the grass, holding his head with both hands, looking at the blue sky without a single dark cloud.

"It feels like it's in conflict with the original me...... Lin Xuan said with his eyes closed.

"Well, let's talk about it carefully!" said Dogen with a smile on the corner of his mouth.

"In the past, although I studied martial arts, I was essentially just an ordinary person, integrated into the world of ordinary people, so my blood flowed with the thinking of ordinary people, in the case of peace in the world, I was at most in college to rectify some ruffians and hooligans, and the final outcome was sent to the Public Security Bureau, that time I killed Xiao Fenghu was the first time I killed someone, that time I killed so many people, but I was tied up by Li Xin's matter and had no special reaction, in fact, I am still a kind ordinary person in essence...... Maybe all the time, maybe sometimes I'll be very cold, sometimes I'll be a woman's kindness...... It's a bit of a contradiction, but that's what I ......."

Speaking of this, Lin Xuan sighed, sat up, hammered his head and said: "But when I was using the Killing Sword Dao just now, I felt that I was cold like a robot, and there was only destruction and killing in my eyes, this is not me, even if I have great power, but I will eventually be swayed by this power, and finally lose and become a puppet of power...... I think that's why the Xuanyuan tribe senior who achieved the Heavenly Realm through killing lost himself......"

"Except for a very few people, no one likes to kill from the beginning, you are right, in the end, if you can't keep your heart, you will be eroded by power, and thus become a puppet of power, you can recognize this, the old man is very happy......" Dogen said with a smile.

"Then what should I do?" I have comprehended it now......" Lin Xuan asked with a frown.

"There are three ways!" Dogen stretched out three fingers and shook them in front of Lin Xuan's eyes......

"Well, what method ......," Lin Xuan asked curiously.

"The first way, abolish the source qi and become an ordinary person, you won't be lost in power......" Dogen said with a smashing mouth.

"Don't talk nonsense......"

“......”

"The second method is not to use it, you will lose yourself when you use the Killing Kendo, just don't use it......" Dogen said.

"It's always going to be used, it's impossible to say that you don't use it at all!" Lin Xuan shook his head: "There is no difference between not using it with a strong force and abolishing the source qi, it is better to abolish the source qi and become an ordinary person......

"Then there's only a third way, stripping!" said Dogen, stroking his beard.

"Stripping, how to strip?" Lin Xuan asked, "Isn't stripping just the waste of source qi?"

"Of course not, I'm not talking about stripping the source qi, but stripping the blood crystal system...... " Dogen said with a smile.

"Then what did I come in for, I stripped the blood crystal system, I don't know if there is an increase, anyway, the cultivation of the Heavenly Realm will definitely not be there now...... So what do I rely on to capture the Golden Crystal ......" Speaking of this, Lin Xuan paused and narrowed his eyes......

"Thought of it?" Dao Yuan smiled and said: "You don't have to lose by stripping the blood crystal now, but what about after you get the golden crystal?" The Yellow Emperor and his subordinates relied on the golden crystal to create a clone, so when that golden crystal is in your hands, you can naturally also create a clone, and use the doppelganger to carry the killing sword path, and the deity still cultivates the source qi and walks the road of panic, how about it?"
