When Zhang Qianren came to the bottomless deep canyon at the bottom of the sea, the incomparably terrifying sea pressure immediately pressed the shield outside his body to a small circle.

And at this depth, the eyes are useless.

After all, the sunlight couldn't shine so deeply, and even if he opened his eyes, all he saw was the darkness that he couldn't see his fingers.

Fortunately, the consciousness is not affected.

He placed the Ruyi Golden Hoop on a piece of iron ore and waited quietly.

Through his scattered consciousness, he was able to clearly perceive everything around him.

The speed at which the Ruyi Golden Hoop Rod devours metal is not slow.

But as long as he thought that someone from the sect might have descended to Guanhai City at this moment and was waiting for him, he was worried.

In addition, this bottomless submarine canyon also brought him a lot of pressure.

Zhang Qianren didn't know if there were any terrifying creatures in the deepest part of this canyon.

Although he was at the pinnacle of foundation building, he had no power to resist in front of those huge creatures.

Any big fish with a body size of more than a few tens of meters can ignore his attack and swallow him in one gulp.

In the face of the stomach acid in the stomachs of some sea monsters, which can be easily corroded by even magic weapons, he doesn't think he can resist it.

Moreover, there are few water avoidance charms on his body.

Just when Zhang Qianren was becoming more and more anxious because of the passage of time, Qin Mu, who was leaning back on the chair, had already grinned.

"When you upgrade your Wishful Golden Hoop Rod to level 2, you will receive feedback of +1 Metallic Spirit Root, and you can choose who to give feedback."

After listening to a lot of 'experience points +1' news, the Ruyi Golden Hoop Stick was finally upgraded again.

Qin Mu did not hesitate to set the feedback object as himself.

At the moment when he chose to end, a chill appeared out of thin air from the tail bone, and quickly spread down the spine to the cervical spine, and finally seemed to turn into an ice needle, directly through his mind.

In an instant, Qin Mu only felt that his head was clear.

Immediately after, a chill covered the whole body without warning, like a basin of ice water poured from the head.

Qin Mu subconsciously shuddered.

After a shiver, he stretched out his hands and tried to clench his fists.

"Do I have a spiritual root?"

While he was thinking this, the sound of the Ruyi Golden Hoop Stick gaining experience sounded in his head again.

Qin Mu thought about it, and simply blocked this kind of prompt sound for gaining experience points through the connection with the Ruyi Golden Hoop Stick.

Zhang Qianren, who was deep at the bottom of the East China Sea, naturally didn't know that the Ruyi Golden Hoop Rod had been upgraded again, and was still waiting anxiously.

And in the Qin Mansion in Guanhai City, Qin Mu had already recovered from the excitement of having a spiritual root.

Compared to the things that have crossed over and found that he has a full 99 innate treasures, this kind of thing has not been able to make him happy for too long.

Maybe immortality is possible, but Qin Mu knows very well in his heart that there is not much difference between having 1 spiritual root and not having a spiritual root.

It's just that one is a servant in the Immortal Sect, and the other is a social animal in the society under the rule of the Dayu court.

Therefore, Qin Mu quickly devoted himself to the creation of the 'new book'.

Writing a book is a difficult thing to think about, but when you write it, you feel that you don't think about it at all.

For experienced authors, each chapter has its own purpose, and the whole book is composed of many small frameworks.

In this way, the rhythm will be bright and climactic, and the reader will want to watch it endlessly.

But for an inexperienced person like him, he began to write a running account without even knowing it after writing a few hundred words.

After describing the protagonist and the protagonist's family in dozens of words, he subconsciously wrote an unnutritious family conversation.

"When you upgrade your Wishful Golden Hoop Rod to level 3, you will receive +1 feedback on the Metallic Spirit Root, and you can choose who you want to give feedback to."

It wasn't until the prompt message of the Ruyi Golden Hoop Stick upgrade rang in his ears again that Qin Mu came back to his senses from his state of full devotion.

As soon as he looked up, he realized that it was approaching dusk.

"This afternoon has passed so fast~"

Qin Mu stretched his waist, and after a sigh full of sufficiency, he accepted the feedback from the Ruyi Golden Hoop Stick.

With a chill rushing over him, his metallic spiritual root +1 again.

And Zhang Qianren, who is deep at the bottom of the sea, doesn't feel that time flies at all.

He just felt that life was like a year.

No!

The time is like a year!

Although he didn't know how long it had been since he went to sea, he had a vague hunch...... It's getting dark.

If he hadn't gone back by the time it got dark, those people from the sect would have come to look for him in the sea.

Zhang Qianren sensed the devouring speed of the Ruyi Golden Hoop Stick, and gritted his teeth anxiously, eager to feed the iron ore to it in person.

Wait a minute!

Iron ore?

Zhang Qianren reacted violently.

Although he has been in the sect all the year round, he has also learned that the iron ore contains more than half of the iron, which is already considered a rich mine.

That is to say, he wasted a lot of time in vain, and he had been allowing the Ruyi Golden Hoop Rod to filter iron in the iron ore and then devour it.

Thinking of this, Zhang Qian couldn't help but raise his hand to give himself two slaps.

He hurriedly came to the iron ore that was being devoured by the Ruyi Golden Hoop Rod according to his divine sense.

When he reached out and picked up a piece of rusty iron ore and felt it carefully, his face suddenly changed.

The iron ore contains only one-fifth of its volume, and the rest is sand, rock, and some seafloor deposits.

"Mother's!"

He who had never scolded anyone in decades as a cultivator, couldn't help but scold secretly at this moment.

After scolding, he hurriedly took out a palm-sized alchemy furnace from the storage ring, cast a spell to make it bigger, and then reached out of his hand to throw iron ore into the alchemy furnace.

After quickly accumulating enough iron ore, he used a talisman sealed with a wisp of green flame with a blue face and sat on the rock on the side to refine the iron ore with all his heart.

This talisman was bought by him for fifty lower grade spirit stones, just in case of emergency.

And the temperature of this green flame is extremely high, and ordinary metals will melt into molten iron in a few minutes if they can't withstand this flame.

Even if it was his alchemy furnace, it was very likely that it would not be able to withstand this flame.

But at this moment, Zhang Qianren can't take care of it so much.

He just wanted his golden spirit root to increase more, so that even if the Ruyi Golden Hoop Stick was found by someone from the sect, he would not lose anything.

……

In the city of Guanhai, the Qin family;

After dinner, Qin Mu sat on a chair, his head rested on his arms, and his feet dangled on the table, looking leisurely.

He had wanted to admire the masterpieces he had been working on for an afternoon, but since nightfall, the speed of upgrading the Ruyi Golden Hoop Stick had suddenly accelerated.

Now it has been promoted to level six.

In this tide of joy, he couldn't calm down to read at all, so he simply cleared his mind and stared at the beam above his head.

Not long after, the prompt tone of the Ruyi Golden Hoop Rod upgrade sounded in my head again.

"When your Wishful Golden Hoop Rod reaches level 7, you will receive +1 feedback on the Metallic Spirit Root, and you can choose who to give feedback to."

While adding points to himself, Qin Mu summoned the panel carrying the information of the Ruyi Golden Hoop Rod with curiosity, wanting to see the experience he wanted to upgrade to the next level now.

【Name:Ruyi Golden Hoop Stick】

【Grade: Innate Treasure】

[Grade: LV7]

[Experience: 15/700]

[Characteristic: Ruyi (Seal)]

[Remarks: ......]

After reading the above information, Qin Mu nodded and muttered secretly.

“700？”

"So, every time it levels up, the maximum amount of experience points increases by a hundred?

"This is good news for me, fortunately, the experience points are not doubled, otherwise, I don't think I would have waited until it reaches level 100 in this life."
