Niu Er opened his mouth and walked out.

"Niu Er, now we can only go to find Ye Lao together and discuss a way, understand?"

Niu Er stopped, muttered for two seconds and said:

"So what are you waiting for? ”

Everyone nodded and walked towards the alchemy department.

"Ye Lao?"

The crowd bowed down and shouted softly.

"Uh-huh, it's for the wood dust thing?"

"Yes, Ye Lao, can you reopen the Xuanwu Foundation Secret Realm?"

Niu Er couldn't wait to ask.

"No, before you come? I went to see my master, and I had to wait three years. ”

Fire Spirit, Niu Er, and Lingyun's hearts sank......

"Is there any other solution?" the fire spirit tried to ask.

"Nope. ”

"I understand, Ye Lao, give it, this is what Brother Muchen asked me to hand over to you. ”

"Don't worry, with Mu Chen's strength, staying in the secret realm is not necessarily a bad thing, at least there is a strong aura for him to cultivate, maybe when Mu Chen walks out, it is not impossible to be promoted to Jin Dan. In three days, the school will officially start classes, cheer up, don't be late. ”

Ye Lao spoke, and Huo Ling and the others turned to leave.

Seeing Huo Ling and the others leave, Ye Lao sighed, but his heart was full of relief, and he opened the storage bag, where a shadow stone and a special six-sided crystal were placed.

Opening the Shadow Stone, Mu Chen's figure appeared.

"Master, I'm sorry, but there are some things, someone has to do it, don't they? Suppress the Demon Spring? I'm the most suitable person, Master? There is a Heavenly Dao Crystal in the storage bag, I wish you an early promotion to the middle stage of the Yuan Infant.

By the way, Master, remember to help me collect some Seven Attribute Materials, and when I go out, I can raise the Seven Spirit Beads to the peak of the magic weapon, and as for the cost, Heavenly Dao Crystals will settle the bill, hehe. ”

Mu Chen's smiling face lasted for a long time before slowly dissipating.

Ye Lao raised his head, tears would not flow out, calmed down, took out the Heavenly Dao Crystal, and put it into the dantian.

As soon as the Heavenly Dao Crystals entered the dantian, a massive amount of Heavenly Dao aura was immediately emitted, and almost instantly, the unfinished foundation of the wood dust was repaired, and the perfect feeling of harmony came out, and countless mysteries automatically emerged, and Ye Lao fell into an epiphany.

Qian Lao sensed this aura and hurriedly set up a defensive formation around Ye Lao to prevent the students from accidentally breaking into Ye Lao's epiphany.

In the dormitory, fifteen people were silent, and for a long time the fire spirit broke the deadlock:

"Brother Muchen is not here, but our group can't be dispersed, next, I'll make a cultivation plan for you:

Niu Er, your cultivation plan: within three years, you will be promoted to the Eight-Pattern Golden Pill, Double Vision, pass the assessment, and be promoted to the Golden Pill Stage Spirit Master, Third-Order Peak Alchemist, Third-Order Painter, and Third-Order Appraiser, you have to do it if you can't do it, understand?"

"Understood. ”

The difficulty was extremely high, but Niu Er still roared.

"Lingyun?, your cultivation plan: within three years, you will be promoted to the Nine-Pattern Golden Pill, or even higher, at least you must be the Bright Moon Vision of the Sea Birth, pass the assessment, and be promoted to the Jindan Stage Spirit Master, and all the nine professions will reach the late stage of the third order, or even the peak. ”

"Well, I'll try. ”

Lingyun nodded.

"Yu Guang? Your cultivation plan: Ascend to the Eight-Pattern Golden Pill within three years, double vision, and pass the assessment? Promoted to Golden Pill Stage Spirit Master, Third-Order Peak Puppet Master, Third-Order Peak Talisman Master, and Third-Order Planter, can't you do it? Wait for Brother Muchen to come back? Explain to him yourself. ”

"Uh-huh. Yu Guang nodded.

"Xu Guanghui, your cultivation plan......

Water Dream?Your Cultivation Plan......

Mu Ling: Your cultivation plan...... Learn from the delusional teacher, don't be lazy, and you will become an indispensable candidate for the team in the future. ”

"Uh-huh, I know, Fire Spirit. ”

"Yu Fan, what is your cultivation plan......

Butterfly Spirit, your cultivation plan .......?"

The fire spirit planned everyone's cultivation plan, which was extremely difficult.

"Fire Spirit, Cultivation Plan: Upgrade to the Nine-Pattern Golden Pill within three years, Red Lotus Burning Sky Vision, promote to the Golden Pill Stage Spirit Master, Nine Professions be promoted to the peak of the Third Order, and at least one career will break through to the Fourth Order ......"

Uh, the fire spirit is even more ruthless with himself......

"Three years is not a long time, but when Brother Muchen returns, we will leave him far behind and let him catch up. ”

"Good. ”

Fifteen people shouted in unison, deafening.

Without taking any breaks, fifteen people walked out of the dormitory and got busy.

Three days later, the school opened, and the cost of 30,000 spirit stones was nothing to Huo Ling and the others......

Mu Chen did not report it, but the school still retained Mu Chen's student status, waiting for him to come out of the secret realm.

The news that Mu Chen had not come out of the secret realm spread so much that not only the Canghai Academy, but also the entire Xuanwu City, was known to almost everyone, and they praised it one after another.

This news reached the ears of Mu Mian and Yu Rou, and Mu Mian was proud of it, but Yu Rou cried all night......

It took a long time for Yu Rou to recover from her grief......

In the secret realm, Mu Chen kneels on the altar, waiting for the evil demon to appear.

Sixteen hours appeared, a demon that had built the pinnacle of the foundation......

It took Mu Chen a breath of effort to slay him, and the rest of the time was spent on cultivation, four hours for contemplating the nine professions, and the remaining two hours for clearing the demons in the secret realm.

The battle record is remarkable, and the wood dust makes the demons dare not approach the range of the Demon Slaying Array.

Time passes slowly......

On this day, Mu Chen killed the tenth demon at the peak of the foundation building, waited patiently, and according to the established law, the next one to appear should be the demon of the Jindan period.

However, sixteen hours later, another demon that had built the pinnacle of the foundation emerged and was slain by Mu Chen.

When Mu Chen slays the hundredth demon at the peak of the foundation, he leaves the altar, walks out of the demon slaying array, and rushes around the secret realm to kill the evil demons.

Wood Dust's Goal: No More Demons in the Secret Realm......

Hmm? There's a demon hiding in the early stage of the Golden Pill here?

Mu Chen's spiritual sense swept and found this demon, slashed through the sword, slashed it, put away the storage ring, inherited the crystal, and left.

This demon in the early stage of Jindan?Originally, he wanted to let the demon in the foundation building stage consume the energy of the Demon Slaying Array before attacking, but he didn't think that he would be killed now, obviously he was already well hidden, why......

It took more than a month of hard work to kill the ten thousand demons in the foundation building period, and the demons in the early stage of the three-headed golden pill, and successfully eliminated all the demons in this secret realm.

Not to mention, the harvest is remarkable, and Mu Chen even opened a furnace to refine pills such as Broken Ji Dan......

Life in the secret realm is destined to be boring, but Mu Chen can endure it and enjoy it.

In the blink of an eye, half a year of hard work has passed......

In the past six months, Mu Chen has successfully killed two hundred and forty demons at the peak of foundation building......

The comprehension of the nine professions: Refer to the nine professions given by the painter system in your mind, and go to the next level.

On the first floor of the central golden pedestal in the dantian, there were already more than 10,000 golden aura aura.

Mu Chen was a little helpless, at this rate, he had to be in the year of the monkey to be promoted to Jindan?

Thirteen layers of abutments, each layer has to gather 99,999 to the Golden Intent Aura, at the current rate, and it will take at least a hundred years to promote itself to the Golden Pill, and this is still within the Xuanwu Secret Realm, when the spiritual energy is sufficient.

If it is in the outside world, it is estimated that it will not be able to break through to Jindan by its own old age.

No, we have to change the status quo...... Mu Chen put the target in the spirit stone mine, but fortunately did not hand over the Heavenly Dao puppet to Niu Er, and used the existing materials to slightly modify the Heavenly Dao puppet into a mining puppet, and put it in the best spirit stone mine and was responsible for mining.

Mu Chen, on the other hand, arranged a small spirit gathering array on top of the altar, using the best spirit stones as the base of the formation to increase the concentration of spiritual energy.

The arrangement was complete, and liquefied aura appeared in the Spirit Gathering Array, and Mu Chen's cultivation speed was doubled......

Fifteen people in the Canghai Academy, including Niu Er, are working hard to cultivate and study, and they have improved a lot......

There is no shortage of spirit stones at all with the materials given by Mu Chen, and you only need to devote yourself to learning and cultivating.

From time to time, everyone would look in the direction of the Xuanwu Secret Realm, silently in a daze.

Time passed again, and in the blink of an eye, it was another half a year.

Huo Ling and the others took the flying boat back to Taixing City, reunited with their parents, and went to Mu Chen's house to explain Mu Mian and Yurou's heroic deeds to Mu Mian and Yurou, so that they could be relieved......

Fifteen people have grown up very quickly after Mu Chen's departure for a year......

In half a year, the Heavenly Dao puppet successfully collected all the top-grade spirit stones, a total of 3,700 top-grade spirit stones, enough for Mu Chen's cultivation for ten years.

But just at the moment when the Heavenly Dao puppet wanted to continue digging, the sound of gold and iron sounded, as if it had touched some formation, Mu Chen slashed the evil demon and went there, explored carefully, and finally determined that this was a fourth-order sealing formation.

The sealing formation took the initiative to crack a hole, and a rich spiritual energy escaped from it, and even condensed the spiritual liquid, slowly oozing out, and this concentration was already almost the same as that in the spirit gathering array.

It is precisely because of such a strong aura that there are so many top-grade spirit stones, forming a spirit stone mine......

Mu Chen's seal has a bold guess: the spiritual eye...... Even if it's not a Psicle, it's an item of the same level as the Psychic Eye.

Mu Chen's heart became hot and began to break the formation.

The complete fourth-order formation?Muchen can't break it now, but the fourth-order formation with gaps and flaws?Muchen wants to try it.

What kind of formation is it?

Mu Chen asked the artist system in his mind.

Ding, do you agree to spend your whole body aura to know?

Agree.

Ding, this formation is the pinnacle of the fourth order, the Spirit Sealing Array, which is used to seal valuables and prevent the leakage of spiritual energy......

A complete array diagram turned into a stream of consciousness and entered Mu Chen's mind, which was very cumbersome.

How to break the formation? Mu Chen asked again.

Ding, the level is insufficient, the aura is insufficient, and the answer cannot be obtained.

Well, there's no way but to rely on yourself.

As a result, the law of Mu Chen's life changed.

Every day, the foundation building demon will be killed at a fixed time, and the ten hours of cultivation time will not change, and the rest of the time will go to the spirit stone mine to crack the fourth-order formation.

Peeling off the cocoon, carefully analyzing, combined with the array diagram in his mind, Muchen has new insights every day, but after trying, none of them succeeded.

Day after day?Mu Chen's formation master career is improving extremely quickly......

The fourth-order sealing array was broken by Mu Chen, allowing it to see the hope of cracking.

Slay demons, cultivate hard, and break the formation.

In the blink of an eye, half a year's work passed in a flash......
