The cloud-piercing boomerang swirled like a butterfly, flickering with cold light hovering around the sword-clawed tiger, and under Mu Rui's control, it hit the dead end of the sword-clawed tiger's sight again and again.

The Sword Claw Tiger reduced its attack on Mu Rui and Yi Qian, turned around, and swung its sword claws into a battle with the boomerang.

Bang bang bang!

It's a very fierce collision again!

The minions of the sword-clawed tiger are the weapons of its attack. The boomerang occasionally turned to its back, which was out of sight, and quickly made the sword-claw tiger anxious when it attacked its tail and other inconvenient places.

The reptilian has not yet evolved to the point where it can walk upright like a human, and its most fatal weakness is its back.

They are able to attack the enemy in front of them with great precision, but they have little way to deal with the opponent in the back.

The boomerang, on the other hand, is very agile in the air, and can easily fly behind it to attack. When the Sword Claw Tiger turned around to stop the boomerang attack, the boomerang flashed into a corner that it could not defend against.

"Let's go!" Seeing that the Sword Claw Tiger had no way to parry the boomerang's sensitive attack rhythm, Mu Rui knew that he had an advantage, so he said to Yi Qian.

The two stepped forward and formed a triangular encirclement with the boomerang, frantically attacking the sword-clawed tiger who had no time to take care of the three sides.

At this moment, the sword-clawed tiger, which originally had an absolute advantage, was completely defeated. Due to the scattered sources of the three-way attack, its slashes could not control the range of movement of Mu Rui and Yi Qian as before. Mu Rui's agility has improved a lot, and he can easily dodge almost any of his sword claw slashes.

Bang bang bang!

Mu Rui's soul shield blocked several attacks from the Sword Claw Tiger, and the boomerang once again appeared behind it coldly, giving the Sword Claw Tiger's tail a head-on blow again and again, making it miserable!

It would never have thought that this time it would be planted in the hands of these two hairy boys!

Layers of tiger hair fluttered down like reeds under the cutting of the boomerang, and his tough body was no match for the sharpness of the treasure, and soon cut out blood marks, revealing bright red tiger meat!

Whew—

This time, it became the prey instead, and had to face the slaughter of Mu Rui and Yi Qian!

Seeing that the Sword Claw Tiger was at a disadvantage, Mu Rui took advantage of the situation to attack, speeding up the speed of soul power. Aura spread out from him, and the rich soul power rolled up bursts of flying dust. Under his guidance, the wind whirlwind raged wildly, attacking and killing the sword-clawed tiger!

Yi Qian cooperated well beside him to assist Mu Rui in attacking. His soul power level is far from Mu Rui and Sword Claw Tiger, but in terms of cooperation battle, he and Mu Rui have reached the highest tacit understanding!

The sword-clawed tiger was entangled by the two of them, and soon a sharp blood mark was draped on his body!

Mu Rui's thoughts at this moment changed from running away to killing the Sword Claw Tiger!

You must know that the value of the third-grade sword claw tiger and the magic core is immeasurable!

"Yi Qian, let's kill this sword-clawed tiger and take its demon core!"

Mu Rui said loudly.

"Good!"

Seeing that he had an absolute advantage, Yi Qian's heart was full of confidence. Since it was this sword-clawed tiger who attacked them first, then don't blame them for being ruthless!

The magic core of the three-grade demon beast is beautiful just thinking about it!

Mu Rui was empty, condensed a whirlwind and turned into a sharply shaped wind spear! The wind spear slowly moved behind him, gathering strong strength!

Wow!

At the moment when the sword-clawed tiger's waist was exposed in front of Mu Rui, the wind spear instantly stabbed over, causing a serious injury in the sword-clawed tiger's waist!

Whew—

The sword-clawed tiger groaned again. This time, the momentum of his attack became weaker and weaker. Obviously, the blow from the Wind Spear had already caused him severe injuries in his body, making it impossible for him to respond flexibly to other attacks.

This is an opportunity!

A trace of murderous intent flashed in Mu Rui's eyes!

Take advantage of your illness to kill you!

With a sliding step, he slid his body against the grass, and almost instantly, he was already under the belly of the sword-clawed tiger. The sword-clawed tiger didn't have any defense, only heard Mu Rui shout "Dart coming!", and suddenly, a sharp edge flashed, pierced through the back of the sword-clawed tiger, passed upside down, and held it in Mu Rui's hands!

The blood slowly flowed down the boomerang into Mu Rui's palm, and he didn't give the sword-clawed tiger a chance to breathe, he held the boomerang tightly and stabbed it into the sword-clawed tiger's belly again!

Wow!

Suddenly a cut was made, blood splattered on his face, and the bright red internal organs were clearly visible!

The sword-clawed tiger had no strength to resist, and in a few moments, he lay on the ground, motionless.

Mu Rui slowly crawled out from under the tiger's belly, and didn't care about dealing with the blood all over his body, so he walked to the tiger's brain of the sword-clawed tiger, raised the knife in his hand, and took out the demon core.

Slowly emerging from the blood-red skull, the purple demon core flickered with a faint light, faintly revealing a mysterious aura. It pulsed slowly, slowly flying into Mu Rui's ring.

"The demon core of the third-grade sword claw tiger can be sold for at least fifty spirit stones!" Yi Qian's eyes lit up and he said excitedly.

Mu Rui shook his head: "This thing is not for sale, we use it for our own cultivation." ”

If he hadn't found the secret of the lava pool before, he might have considered selling the magic core and exchanging it for spirit stones for cultivation. But now that I think about it, there is no shortage of spirit stones, what is missing is the essence of the demon beast spirit blood in the demon core. This essence, although it is not like a spirit stone essence, can help a martial artist to directly improve his soul power, but it has an indispensable role in improving the physical strength of a martial artist.

Especially a demon beast like the sword-clawed tiger, its own aggressiveness is extremely strong, and although the strength of its physical body is not as tough as some demon beasts with scales and horns, his minions can directly confront high-grade treasure weapons. Therefore, his own qualifications are also incomparable to many other demon beasts.

In comparison, it's better not to sell it and use it for your own cultivation.

Back at Yi Qian's house, Mu Rui took him to the middle of the courtyard and said, "Yi Qian, let's start cultivating now, and strive to break through the sixth rank of your soul power within three days!"

"What, is it starting so soon?" Yi Qian was stunned. They had just killed the Sword Claw Tiger, and they hadn't even taken a break before they were going to cultivate again?

"Time is pressing, don't you want to pass the family's test?" At this moment, Mu Rui's face was full of seriousness. It's like being a strict mentor.

"Okay! Start cultivating now!" Seeing Mu Rui's very serious appearance, Yi Qian couldn't help but clench his fists, and his attitude became serious.

This test was his last chance to raise his head in the family. He also didn't want to be treated as a waste wood by the other disciples of the family for the rest of his life. In comparison, being insulted by others is far more uncomfortable than dying!

It's been three years, three years of being looked down upon by others and treated like a brute, this feeling, he has had enough!

This time, you must fight a good turnaround!

Yi Qian made up his mind

。

Just when he was still hesitating about what kind of way Mu Rui would use to cultivate him, he found that a ray of light appeared from Mu Rui's divine consciousness space, flickering and staying in front of him.

The light spread out, forming a circular formation that enveloped him.

"This formation is prepared for training martial artists below the level of a first-grade soul master. Mu Rui said, when he hadn't entered the soul master level back then, Senior Brother and Master used this formation to cultivate him, "Its difficulty is about six levels of soul power, you now find a way to break out of the formation." ”

"Good!"

Yi Qian responded, took a step, and walked towards the outside of the ring formation. Just as he was moving his steps, a golden light appeared on the periphery of the soul seal formation, turning into a phantom and rushing towards Yi Qian.

Although the golden light was not strong, it was very stinging when it hit Yi Qian's body.

Yi Qian hurriedly used his soul power to protect his body, but the phantom quickly disappeared.

Yi Qian looked at his body and found that the phantom had not caused any external injuries to him. He felt a strange feeling in his heart.

Obviously, the feeling of labor pain is very real......

"The phantom attack in this formation will only have an effect on your martial soul. And your physical body will not be directly damaged. Mu Rui said.

It is precisely because of this special attack method that the martial soul of the warrior in the formation can be constantly hit and tempered. This method of cultivation is far safer and more efficient than those that cause direct harm to the body.

"In other words, every time I am attacked, my martial soul will be refined?" Yi Qian asked, he seemed to understand the role of this formation.

"Yes. Mu Rui said, "If you want to break through the sixth-stage soul power, you must at least be able to get out of this formation with your own ability." And every time you are attacked by the phantom, your martial soul will be slightly torn and then healed quickly, and in this process, the strength of your martial soul will continue to increase. ”

"Understood!" Yi Gan said.

A look of joy appeared on his face. This formation can temper the martial soul, and it can also help you stabilize the foundation of the martial soul, which is really good.

In his eyes, there was already a blazing battle intent.

Vow to get out of the formation and break through the sixth-stage soul power!

He strode and rushed to the edge of the formation. The ring moves with him, changing direction from time to time. In the formation, there were constantly one after another soul power phantoms, attacking Yi Qian.

The speed at which the phantom was generated became more and more rapid, and soon, Yi Qian had to face the attack of more than a dozen phantoms.

Again and again, the phantom raids, and the shock of soul power stirred up layers of qi waves in the space, tumbling and pouring out towards the periphery of the formation.

Yi Qian dodged sideways, and then waved his arms out, and the palm wrapped in soul power slammed into the phantom fiercely!

Bursts of soreness and numbness spread throughout his body.

There was not a trace of scars on his body, and the slight cracks on the martial soul were healing rapidly, and every collision caused his soul power to be nourished and refined, and the martial soul became stronger and stronger!

Beads of sweat the size of beans appeared on Yi Qian's forehead. He could clearly feel that this kind of trial required a high level of tenacity and strength in his body!

Sure enough, cultivation is not achieved overnight. If you want to stand taller than others and see farther, you must endure the unbearable suffering and pain of ordinary people!

Bang bang bang!

As far as his eyes could see, three or five phantoms slowly rose.
