The next instantaneous instrument tripod opened, and the wood dust spiritual sense controlled Niu Er's blood to enter the instrument tripod.

The surging flame momentum and the rich and outgoing breath of life were mixed out, the red light and green light were entangled with each other and sprayed out, generating and restraining each other, and the buzzing sound emerged, as if celebrating the new life, and the breath of the foundation building peak magic weapon emanated, Niu Er's heart was happy, his fists were clenched, and his heart was full of anticipation.

Nine drops of blood entered the Ding, and immediately turned into a blood mist and drilled into the fire wood pearl, Niu Er only felt a blood resonance connection established, and could faintly feel the joy of the fire wood pearl.

At this point in refining, the Fire and Wood Symbiotic Bead has been refined, but the wood dust has not stopped, and there is still one last step left for him, taking out a piece of ice pattern stone, the pinnacle material of foundation building, and adding it to the instrument tripod for the final quenching.

Success can make the fire and wood grow pearls further, and failure will lose part of its power, and at worst, the magic weapon will be destroyed, and even wood dust and Niu Er will be impacted.

This step was extremely risky, and ordinary third-order refiners would not dare to try it.

This......

The temperature of the instrument tripod dropped rapidly, and the wood dust swallowed five spirit pills, and the spiritual energy was violently injected into the instrument tripod to ignite a raging flame.

Under the two heavens of ice and fire, a little black spot appeared on the firewood twin beads, which were impurities hidden in the depths of the material, and the original firewood twin beads the size of pigeon eggs were shrinking, but the breath was getting stronger and stronger, and the red and green light emitted was more transparent.

Ten minutes later, the cold qi in the ice stone was consumed, the black dots on the fire wood bead no longer appeared, and the wood dust continued to inject spiritual energy to increase the flame for the final quenching.

In the next second, there was a buzzing sound, and a little crack appeared, and it seemed to be a little overwhelmed.

"Niu Er, prop up the earth attribute shield and open the defense talisman. ”

Mu Chen roared and placed a foundation-building pinnacle defensive puppet that had opened all defenses in front of himself and Niu Er, and at the same time placed his spiritual sense on top of the Fire Wood Symbiotic Bead to protect it.

Click, the instrument was shattered, the sound shook for nine days, and a strong impact came, most of which acted on the puppet's body, and the rest directly impacted on Mu Chen's and Niu Er's body.

In the face of such an impact, the shield and the light of the talisman supported by Niu Er's body were instantly torn apart, snapped, and the whole person flew out upside down and was embedded in the wall, breaking seven or eight bones, and seriously injured in an instant.

Although Mu Chen's body was comparable to that of a demon beast in the late stage of foundation building, he still flew out upside down due to this impact, his face lost his blood color in an instant, and the blood spit out in a big gulp, and the breath on his body was sluggish to the extreme, and the whole person's head was crooked and fell into a coma.

It stands to reason that it shouldn't be like this, Mu Chen's injury is even more serious than Niu Er?

Boom, the strong impact broke through the door of the refining room, and there was a crazy catharsis, and even an innocent student happened to pass by and suffered an unwarranted disaster, but fortunately it was only a minor injury.

After the impact was vented, the refining room was in a mess, the instrument exploded, and the fragments were splashed, but it was completely blocked by the defensive puppet to avoid secondary damage to Niu Er and Mu Chen, blocking the damage for Mu Chen, but the defensive puppet was also scattered and in the scrapping stage, and the power of the ten high-grade spirit stones in the body was consumed.

Niu Er spit out a mouthful of blood, took the fire and the wood return pill, came to Mu Chen's side with difficulty, fed the pill to restore the injury into his mouth, and wanted to mobilize the aura to prescribe medicine for Mu Chen, poof, a mouthful of blood spit out.

The dantian was shocked, and the aura was forcibly operated, and Niu Er was injured on top of injury.

The teachers of the Jindan stage and the Yuan infant stage of the alchemy department suddenly came, and when they saw the unconscious Mu Chen, and Niu Er, who vomited blood, they immediately began to treat him.

Fourth-order spells, hydration and rejuvenation, stabilized Niu Er's injuries and grafted his bones.

"Save Brother Muchen first, save Brother Muchen. ”

Niu Er roared.

"Calm down, calm down, Mu Chen's fine, it's just that the soul has been impacted, and the spiritual sense has been depleted, just rest for three days, but you, if you are moving, you have to lie quietly in bed for a month." ”

The Yuan Infant Monk gave the diagnosis and calmed Niu Er.

Hearing this, Niu Er was finally relieved.

"Tell me what's going on. ”

The teacher of the Yuan infant period opened his mouth to ask, Niu Er sorted out his thoughts, and said:

"I asked Brother Mu Chen to refine the natal weapon for me, and I exploded. ”

Well, many of the teachers' faces turned dark, and they immediately showed puzzlement.

Mu Chen's refining level was tested when he entered the school, and it was not a problem to refine the magic weapon that built the peak of the foundation, so why did he explode now?

"Bone Boss? ”

A Jindan monk cleared the remains of the artifact and found a magic weapon that was protected by spiritual consciousness and was unharmed.

"This is a half-step magic weapon, and it's a half-step natal magic weapon, Mu Chen, this kid ......."

Gu Lao took this half-step magic weapon and was shocked, and glanced at Mu Chen deeply, his heart was very excited, and his fingers trembled slightly.

The difficulty of refining the natal artifact is extremely high, and the refiner who can refine the magic weapon at the peak of foundation building may not be able to refine the natal weapon in the middle stage of foundation building, and the difficulty is completely different.

And Mu Chen was actually able to refine a half-step natal magic weapon? Wouldn't that prove that Mu Chen could refine a magic weapon? This is a third-order level.

The broken spiritual consciousness attached to the fire and wood beads gave many Jin Dan and Yuanying teachers insight into why Mu Chen was unconscious.

This kid is really deadly.

In order to keep this magic weapon, he even used his spiritual sense to cover and protect the magic weapon from impact, but fortunately, Mu Chen's soul reached the golden pill, so he only received some impact, otherwise, his soul could be damaged.

The eyes of the teachers Jin Dan and Yuanying kept circulating on Niu Er and Mu Chen.

Mu Chen's willingness to use his spiritual sense to resist the power of the explosion for the sake of Niu Er's natal weapon, and Niu Er's desire to feed Mu Chen's elixir to restore his injuries and catalyze his medicinal properties for Mu Chen's sake of Mu Chen's own injuries is very touching.

"After half a year's assessment, Muchen is exempted from the test, and it is reported that Muchen and Niu Er can participate in the life and death partner plan. ”

"Bone Boss, this is not in accordance with the rules, right? ”

"I set the rules, can't I change them?"

"Uh, yes, old bones. ”

The corners of Mr. Jindan's mouth twitched.

Niu Er didn't know what the teachers were talking about?

"Take Niu Er and Mu Chen to the alchemy department, let Ye Lao take a look, and don't leave any sequelae. ”

"Yes, old bones. ”

......

......

"Niu Er, you are so lucky, you can actually get a natal half-step magic weapon, if you are pregnant and raised properly? Maybe you can have a magic weapon during the foundation building period. ”

After Gu Lao left, the monk of the Jindan period handed Niu Er, the natal half-step magic weapon, the Huomu Xiangsheng Pearl, to Niu Er, and sighed sincerely.

After taking over the firewood twin pearl Niu Er's eyes lit up, the half-step magic weapon turned out to be a half-step magic weapon, Brother Muchen's refining level is really high, it is not a loss, and it is worth it to be blown up again.

Reciting the levitation technique, the Jindan monk led Mu Chen and Niu Er to the alchemy department, and let Ye Lao heal Mu Chen and Niu Er.

After the aura in his body calmed down, Niu Er put this natal half-step magic weapon into the dantian for pregnancy.

The fire wood phase pearl into the body, Niu Er noticed the extraordinaryness of this half-step natal magic weapon, the general magic weapon has to be conceived by the owner, devouring the aura or devouring other items, but the fire wood twin beads are different, entering the dantian directly exudes a rich fire, wood energy slowly nourishes Niu Er's spiritual roots, building abutments, and body, and can even purify the aura.

Sensing Niu Er's injury, the fire wood and pearl wood attributes flowed out to treat Niu Er's injury, and it was as comfortable as soaking in a hot spring.

The natal artifact of the Fire and Wood Symbiotic Bead has been refined by wood dust, and the effect has reached a higher level.

On the other hand, Mu Chen's face was still pale and unconscious.

When Ye Lao saw the tragic scene of Mu Chen and Niu Er, he immediately began to prepare medicinal liquid for them to treat their injuries.

The news of the wood dust refining magic weapon blowing up the Ding spread far and wide, and there was a slight discussion in the school:

"The genius of the Nine Profession Initiates, how could he blow up the Ding?"

"Who knows, maybe his refining deputy position is weaker. ”

"What do you say? Will Mu Chen's assessment fail in half a year? ”

"Brother Tsing Yi, the wood dust has exploded. ”

"Uh-huh, I see. ”

Liuqingshan behaved very calmly, not taking it seriously at all, he... didn't regard Mu Chen as an opponent at all.

The news of the explosion is boiling, and as for the matter of the half-step natal magic weapon, not many people know about it.

Lingyun, Huoling and others got the news as soon as possible, put down the matter at hand and hurriedly came to find Ye Lao, and as soon as they walked into the lounge, they saw Mu Chen and Niu Er who were soaked in the medicine jar, and they only put it down after learning that the two of them were fine.

When they saw Niu Er showing off his natal half-step magic weapon, the group's eyes were bright and they were very envious.

"I really want Brother Muchen to refine a natal half-step magic weapon for me too. ”

As soon as Yu Fan finished speaking, everyone's murderous eyes fell on him.

"Next time, let's let Brother Mu Chen refine the natal weapon, and we will try to choose the early stage of foundation building. ”

"Uh-huh. ”

"Uh-huh. ”

Ahem, with the assistance of the medicinal liquid, Mu Chen coughed twice and woke up from his coma.

"The natal weapon in the early stage of foundation building is far from the half-step magic weapon. ”

Mu Chen coughed and laughed, looked at the more than ten people in front of him, and finally set his eyes on Niu Er.

"The refining fee has increased tenfold, and you now owe me 300,000 spirit stones, Niu Er. ”

"No problem, Brother Muchen. ”

"You too, do you want a half-step magic weapon for your life? ”

"Muchen, don't mess around, if you do it again, if the spiritual sense collapses, it will be troublesome. ”

Ye Lao scolded Mu Chen in public.

"Ye Lao, I have already found the reason for the explosion, and this situation will not occur again next time. ”

Mu Chen coughed twice and reassured.

"You can continue refining, but I'm here. ”

Ye Lao opened his mouth and gave a compromise solution.

"Uh-huh, did you hear that, go and prepare the spirit stone. ”

A group of more than a dozen people disappeared suddenly.

Brother Muchen said that it was okay, then he must choose a half-step natal magic weapon.

......

......

Three days later, Mu Chen and Niu Er fully recovered, went to the classroom, and saw the strange eyes of the students? Mu Chen could only smile awkwardly and did not speak.

In the afternoon, Mu Chen decided to refine the natal magic weapon for Yu Fan, and specially invited Ye Lao to come and protect it.

"Ye Lao, there are two reasons why I can't blow up the tripod last time: first, the quality of the instrument tripod is too poor, and second, there is a little flaw in the method of quenching; ”
