With Yin Jiuchen's roar, the soul power shield that had absorbed the powerful Dao all returned to the Xuantie Sword. Nearly double the speed of action, coupled with the three-percent increase of the Xuantie Sword, coupled with the destructive power of the Blue Flame, plus the feedback power of the two large pincers absorbed by the spiritual power shield, the Xuantie Sword, with the blessing of many powers, exhibited a narrow and deep sword mark on the hard skull of the Lord of Quicksand.

Green slime erupted.

The scorpion trembled all over, stiffened its body, but could no longer make a sound, it trembled all over, and finally fell to the ground.

Bang!

The scorpion's entire heavy body smashed to the ground, and the thin sword marks on the split head cracked nearly thirty centimeters, green mucus flowed out, and the breath of life dissipated.

Yin Jiuchen covered his head in severe pain, and sat in front of the scorpion with no strength, the ground-level martial arts just now forced out all his soul power, and after overuse, it was like boiling hot water in a pot, making his eyebrows tingle and humming, Yin Jiuchen was extremely uncomfortable but there was no way to relieve it.

He sat on the ground for a few moments before he could barely stand up and open his eyes to look around him.

The ground in the cavern, which was originally fairly flat, seemed to have been plowed at this time, and those desolate flame spar veins were shattered into several large pieces. Yun Xiaoyi and Yun Bi Kill were both sent to the empty wall, unconscious, the scorpion's tail was cut off, the head was split in half, and the only one standing was Yin Jiuchen.

Yin Jiuchen kicked the dead scorpion like a child, but he didn't expect the scorpion's hard shell to feed back the force, which shocked his head and made it really decay.

However, with Yin Jiuchen's kick, black fragments fell from the scorpion's trembling skull, falling into the green slime.

Yin Jiuchen was stunned for a moment, and didn't come back to his senses for a while.

What is it?

When the slime was about to cover the black fragments again, Yin Jiuchen finally came to his senses, picked up the black fragments, and carefully examined them in the dim light of the hollow.

This fragment, he has a sense of familiarity, after he defeated the Snow Mountain White Tiger, he also dropped one, could it be that it comes from the same source?

He remembered the inexplicable feeling when the Lord of Quicksand approached him, and thought to himself, is this because of this?

No matter how much you think about it, it is better to verify it, Yin Jiuchen wiped the green slime on the black fragment, and pressed the fragment against the center of his eyebrows, and sure enough, the fragment quickly integrated into Yin Jiuchen's spiritual world, and exuded a cold feeling, relieving the pain of Yin Jiuchen's soul, and a memory was revealed at the same time.

"The method of soul attack!"

The method of soul attack is to let the soul cultivator learn to use the soul to attack, this kind of attack is different from the previous attack of Yin Jiuchen using martial arts to show its power, it is a direct attack on the spirit and soul of the spirit of the spirit creature! This kind of attack can directly give the opponent's brain tingling, so that the caster can grasp the initiative, cultivate to the back, and even directly defeat the opponent's soul, causing the soul to collapse!

If Yin Jiuchen had a memory, he should be able to understand that when he used the black chain sword when he entered the demon, the attack method he showed to Xing'an was a soul attack, not only using the many souls of the black chain sword to interfere and bite, but even directly cooperating with the black chain sword to cut Xing'an's soul in half!

In addition to this information, the soul fragment itself also carried pure soul power, and after Yin Jiuchen fused it, the huge soul power contained in the fragment directly raised his soul level to the sixth level of the imperial qi!

Yin Jiuchen breathed a long sigh of relief, his lost heart was slightly excited, he didn't expect that the black fragment actually contained such a powerful spell, but the soul attack can't be used casually, this attack method is better to be less exposed, and with Yin Jiuchen's current soul strength, at most, it can make the opponent's soul a little stinging, and it doesn't have any effect.

Yin Jiuchen gathered his thoughts and walked towards Yun Xiaoyi, if she hadn't taken the lead in using the ground-level martial arts in front of her and shaved off the tail of the scorpion, Yin Jiuchen's battle would not have been so simple.

Passing by the center of the hollow, Yin Jiuchen saw the desolate flame essence that had been hammered into pieces by the Lord of Quicksand, and couldn't help but smile, this essence was already incomplete, and it was estimated that it would not be able to sell for 100 million gold coins.

However, when Yin Jiuchen's gaze swept over the yellow desolate flame essence, he unexpectedly saw a fiery red, heart-like stone. Yin Jiuchen picked it up in surprise and looked at it in front of him.

The fiery red tone, the glass-like transparency, densely covered with naturally formed lines, and the aura contained in it is extremely pure.

Could it be that this is the Heart of the Earth?!

Yin Jiuchen held back his excitement and looked at the red spar in his hand, he had never seen the heart of the earth, but this spar was too special, and it appeared in the veins, nine times out of ten it was the heart of the earth.

His meridian problems were saved!

Putting away the heart of the earth, Yin Jiuchen walked towards Yun Xiaoyi, who was unconscious, and Xiao Zi anxiously circled around the girl, her eyes full of tears. I didn't expect this squirrel to be so human.

"Don't worry, your master is not dead, he just passed out. Yin Jiuchen probed Yun Xiaoyi's breath and explained to the squirrel, not knowing if it could understand what he said. He picked up Yun Xiaoyi, found a good place for her to lie down, gave her a healing elixir, and saw that the girl's face was better, and finally put her mind at ease.

As for Yun Killing, Yin Jiuchen was not in the mood to take care of a person who was making things difficult for him everywhere, so it was good that he didn't take the opportunity to do the blackout.

Yin Jiuchen doesn't plan to continue moving, this one is the master of quicksand who dies, and the other should also be killed by Jin Wu, Yin Jiuchen is the safest to stay here, the passage under the sand is complicated, and there are people who need to be taken care of around him, and he can't find his way out for a while now, and Yin Jiuchen believes that his teammates above the sand will definitely find a way to find him.

......

Not far from the place where the Lord of the Quicksand was in trouble, a huge bird flew low, this bird was white, with a wingspan of ten zhang wide, and it flew quietly, light and fast.

"Is the token's distress signal ahead?" On Shiratori's back, the beautiful man stood steadily, carefully observing the things around him. Beside him, a man dressed simply, with the gentle air of the big sister next door, was looking at the plate in his hand, on which a green dot was constantly flashing.

"Yes, it's close. ”

One of these two people is Mentor Ke Yu, and the other is his eldest disciple Su Yu, and it was Xia Lian who sent them a distress signal at this moment.

In addition to them, there are two other groups of teams approaching, both targeting the land where the Lord of Quicksand is causing chaos, and the other two academies also have people who send signals to their teachers.

The battle of Jin Wu is nearing the end, and the mercenaries have also found a way into the underground and began to search underground.

The death of the two quicksand lords is just the beginning, and it doesn't take long for the void where Yin Jiuchen is located, which is full of desolate flame crystal mines, to become the next to fight.
