Lin Feng looked at the ten first-level low-grade spirit stones in front of him, and felt unreal.

These ten first-level low-grade spirit stones are the rewards Lin Feng earned from working hard to upgrade the Fire Refining Array in the past two days. They were originally 100 pieces of spirit stones, but Zhao Dalong didn't know where the channels came from, and they all changed to first-level low-grade spirit stones.

"Technical monopoly is indeed huge profits, no wonder so many countries have put in any technical barriers in their previous lives."

He sighed.

With the spirit stone, Lin Feng considered upgrading the formation.

Now there are eight formations in his hand:

They are: Light and Shadow·Stone Detection Array (first-level middle-grade formation), Fire Refining Array (first-level low-grade formation), Spiritual Recognition Array (not-level low-grade formation), Spiritual Locking Array (first-level low-grade formation), Turtle Spirit Protective Array (first-level middle-grade formation), Information Ban (first-level middle-grade formation), Information Replication (not-level middle-grade formation).

And two magical formations: Gold-breaking Claws and Iron-Devouring Ruins!

Except for the first light and shadow and stone detection array obtained from the Ling Iron Ore Cave, the others were obtained from this giant bamboo forest.

I have to say that the level of the outer disciples has indeed allowed him to have more cultivation resources!

Lin Feng began to think about which formation to upgrade.

Finally, he set his eyes on the turtle spirit body protection array.

The reason for upgrading this formation is not because he needs this the most, but because other formations are either not necessary to upgrade for the time being, or they are not needed at all, or they are not needed, or the spirit stones are not enough to be upgraded.

The turtle spirit body protection array becomes the most suitable at this time.

He took out the turtle spirit armor coat from his storage pocket and put it in his hand, and then inputted mana. The palm-sized turtle spirit armor coat expanded rapidly, and in a blink of an eye it turned into the size of a large iron pot.

This is the effect of Ruyi Stone!

As the mana is input, it becomes large and large. This is the function of a spiritual ore such as Ruyi Stone.

As for spiritual iron, it is a basic material for the manufacturing of magic weapons. It is as basic as the iron in the previous life in the world of immortal cultivation.

Lin Feng turned over the turtle shell, released his spiritual consciousness inside the turtle shell, unlocking the formation of the spiritual consciousness lock forbidden formation, and the array pattern of the turtle spirit protective array appeared on the inner wall of the turtle shell.

Lin Feng looked at the Baiwu text that appeared, and without hesitation, he directly chose two of them to unlock them.

······

[1: When driving the formation, the mana consumed -50%. (Spend two first-level low-grade spirit stones)]

[2: At the cost of damaging the array carrier, the entire defense effect of the turtle spirit protective array will be increased by one level in a short period of time. (Spend a piece of low-grade spirit stones)]

······

Three first-level low-grade spirit stones quickly turned into empty shells, and then a large amount of array knowledge was instilled into his mind.

After a long time, Lin Feng completely controlled this knowledge.

While he was thinking, he took out the array pen and the drawing array liquid. After he had sorted out his ideas, he decisively began to draw the formation inside the turtle shell quickly.

After a while, Lin Feng picked up his pen and finished his work!

New Baiwu texts also slowly emerged.

······

[5: Unknown function. (It will cost one first-level low-grade spirit stone to find out)]

[Introduction: You can't hit me, but I can hit you.]

······

Lin Feng nodded secretly.

Now this medium-grade magic weapon is enough for him to use for a long time, and he doesn't have to worry about the exhaustion of mana and insufficient defense.

It is his most powerful equipment!

And at the same time.

In the bamboo forest not far from Linfeng Bamboo House.

Sun Lian and Zhang Hai hid behind a cluster of bamboos and looked at Lin Feng's bamboo house from afar.

"Senior Brother Sun, do we really want to kill Lin Feng?" Zhang Hai hesitated.

Sun Lian glanced at him coldly:

"What? Want to quit?"

"No, no." Zhang Hai couldn't help but shake his head when he saw Sun Lian's eyes, and then said worriedly: "I'm just worried about Senior Sister Li Qingyun."

"What's there to worry about?" Sun Lian sneered, "That timid guy has completely lost his courage since the incident four years ago. He hurried in his bamboo house every day. He wouldn't go out without any matters. And now it's midnight, why did she come here for nothing?"

"And didn't you say that too? Although Lin Feng had communicated with Li Qingyun several times, they didn't seem to be very familiar with each other. Since that's the case, there's no need to worry."

Zhang Hai lowered his head.

Seeing this, Sun Lian said coldly:

"It seems you are really afraid, and what you are afraid of is not Senior Sister Li, but the risk of potentially revealing the secret, right?!"

"I know you are timid, but have you ever thought that although you and I are both eighth-grade spiritual roots, if you don't want to venture deep in the bamboo forest, how long will it take for us to upgrade to the ninth level of Qi Refining Realm? How slim is the chance of building a foundation?!"

"If you don't take risks at this time and compete for the resources of practice, what should you do when you face the situation when there are no resources of practice?"

"I'll ask you." He stared at Zhang Hai and shouted: "Did you forget how you looked when you first came to the giant bamboo forest? Have you forgotten that you were almost dragged out of the bamboo forest by the law enforcement team after you didn't hand over the Ruyi Stone in time? If I hadn't saved you, you would have become a pile of dry bones outside the bamboo forest now!!"

"I haven't forgotten!" Zhang Hai clenched his fists, "Senior Brother Sun, needless to say, I'll go!"

Sun Lian frowned, a little dissatisfied with this guy's condition, but there was not so much time at this time, he said:

"The spells I practice are not suitable for quick and secret killing, so you will fight the Pioneer later."

"I remember the spells you mainly practice are stealth and matter control, right?"

"right······"

"This is for you." Sun Lian gave him a dagger, "This is a first-level mid-grade magic weapon - Qingbian, I lent it to you. You can hide first, and then directly give the kid a blow when he is not paying attention!"

"The Qingblade is very lethal when approaching, and it also has a very strong toxin. As long as the kid is stabbed into a little wound, he will definitely be dead within a moment!"

"But for the sake of creating trouble, you should try to kill him at once, do you know?!"

Zhang Hai's face gradually showed a ruthless look and nodded heavily.

He pinched the marks with both hands and recited the magic tricks on his mouth. Then he put his index fingers together and aimed at the green blade in Sun Lian's hand. The green blade floated and stood above his fingers.

Then he casts the spell again, making his body transparent, and he can only faintly see a little transparent outline.

He quietly walked towards Lin Feng's bamboo house.

Soon he came outside the bamboo house. Zhang Hai went around the window to the right and looked into the room through the gap at the edge of the window. Then he saw Lin Feng meditating and practicing on the futon inside the house, and next to him were piles of array plates.

The murderous intent flashed in Zhang Hai's eyes.

When he reached this point, he was also very hesitant!

He stepped back, his spiritual sense spread out, covering the bamboo house in front of him, and soon realized Lin Feng's position.

The blue blade on his finger let out a soft moan.

"Kill...what!?"

Before he could release the green blade in his hand, a ball of white shadow suddenly jumped out from the ground and hugged Zhang Hai's face directly. Zhang Hai only had time to panic and screamed, and the ball of white shadow slashed heavily on the face twice with its thick and sharp claws.

"Shit!"

Xiaobai fell to the ground and screamed, hissing and fierce, his blood-red claws and ferocious expressions showed his fierce look.

Zhang Hai fell to the ground without any recognition, and a large amount of blood flew out from his face and neck, dyeing the surrounding land red.

"Protecting the Body Spirit Beast?"

"Sun·····Senior Brother Sun··················································"

After tilting his head and saying this, he widened his eyes and lost his breath.

Bang!
