When Lin Yi jumped out of the blind corner of his gaze and looked down at the pile of rocks in the Yantian Great Array from a high altitude, he suddenly found that the pile of rocks under him had completely changed to another scene.

These stones are not placed randomly, from Lin Yi's point of view, it is faintly found that the combination of these chaotic stones looks like a huge palm that has just broken through the ground.

If you think about it along this line, these 'stones' are probably not stones, but bones!

"Shhh

Lin Yi gasped, looking at this blurred palm in disbelief, his heart was extremely shocked.

Among these bones, even the smallest one was larger and taller than Lin Yi, which showed how wide the palm formed by so many bones was.

If we continue to deduce downward, what kind of horror is the owner of this palm?

Lin Yi pondered for a moment, slowly lowered his figure, waved the giant sword, and began to carefully dig out the soil under each bone, without touching the position of the bone.

After a day and a night of non-stop busyness, Lin Yi had dug down to a depth of nearly twenty zhang, exposing the entire arm connected to this palm in front of him.

This is a huge severed arm, digging to the end, Lin Yi can clearly see the knife-like wound out of the severed arm.

With a length of twenty zhang, the entire arm was exposed to Lin Yi's eyes.

"Boom!"

At this moment, this arm suddenly bloomed with a dark red light, and a fierce aura suddenly descended, filling the entire deep pit.

Lin Yi felt it most clearly, even if he had been prepared, but this fierce aura still passed through his body, going straight to his internal organs, and it was difficult to resist, like a mighty primeval beast devouring Lin Yi.

Lin Yi's face changed greatly, and his hands and feet were cold in an instant.

"Buzz!"

Attacked by the ferocious aura, the immortal sword body suddenly became ferocious, and the blue qi and blood rose, as if setting off a stormy wave, and at the same time, the sound of the sword roared continuously.

The sharp and fierce sword qi crisscrossed the body, smashing all the fierce qi that had just entered the body.

At the same time, feeling this breath, Lin Yi also guessed the origin of this arm.

This is not a man's arm, to be precise, it should be the severed arm of an ancient beast!

This level of ferocity is only possible for the primeval beasts recorded in ancient books.

The primeval beast has long been extinct in the Flood Desolation, and it is equivalent to the existence of the gods of the heavenly realm.

The severed arm emitted a dark red glow, and the ferocious aura became more and more intense, but it did not pose the slightest threat to Lin Yi.

Lin Yi even had an illusion, as if this fierce qi felt the power of qi and blood in his body, and he was faintly afraid.

At this moment, there was a trace of abnormal movement in Lin Yi's various acupuncture points.

Lin Yi's heart sank, and after feeling it carefully, he found that Zhou Tianxingchen's flags, which were originally hidden in various big holes, shook again and again, and seemed to be extremely excited.

"Huh?"

Lin Yi's heart moved, and he remembered what the divine stick said to him at the top of the Immortal Mountain.

The god stick once said that the level of the Star Banner can be increased, and there are two ways, one is to add rare materials to it, and the most suitable for refining the banner is the bone and skin of the primeval beast, and the flesh and blood are integrated into the flag, which adds more power. The second method is more time-consuming, and requires one's own perennial sacrifice, and after a long time, the level will naturally rise, and the power of the formation will also increase.

Lin Yi's Star Banner has been damaged in the Battle of Hundred Battles Valley to this day, and it has not been repaired, let alone upgraded to a higher level.

But the broken arm in front of him is tantamount to sending charcoal in the snow to Lin Yi's Zhou Tian Xingchen flag.

The severed arm of this primeval beast, if you are an ordinary person, may not know how to use it, but for Lin Yi's star flag, it is equivalent to a great supplement.

"No wonder Zhou Tian Xingchen Banner was so excited, it turned out that they also felt the breath of the primeval beast. ”

Lin Yi was overjoyed.

If Zhou Tian Xingchen Banner can be repaired and the level can be upgraded, it will be equivalent to adding another big killing weapon, and it is Lin Yi's most powerful means so far!

The previous Zhou Tian Xingchen Banner was enough to suppress the monks of the Jindan period.

If this time can raise the level of Zhou Tian Xingchen Banner, it is very likely that it can threaten the Yuanying Great Cultivator! The probability of success in that matter will be one more point!

Lin Yi no longer hesitated, he sat cross-legged in the cave, and with a movement of his consciousness, more than 10,000 star flags flew out from the acupoints in various parts of his body, densely packed, like stars in the night sky.

Under Lin Yi's control, the severed arms of the primeval beasts rotated in clusters, and each star banner was shining with mysterious starlight, circulating a trace of star power.

Nearly half of the star flags still have some faint cracks on them, and many of the star flags have recovered a small half of the power of the stars.

Lin Yi scolded lightly, and the magic tricks in his hand changed one after another.

Spiritual power burst out from his fingertips and shot into the severed arm of the fierce beast, Lin Yi's divine sense continued to differentiate, and after reaching the limit, it was still expanding and spreading.

There is not much time left for Lin Yi, he must race against time to get out of here and reach his destination before the Demon Punishment Battlefield reopens.

More than 10,000 star flags wrapped the murderer's severed arm tightly, almost impermeable to the gaps.

Under the continuous blessing of Lin Yi's mana, the bones of the fierce beast were consumed and worn down little by little, and the dark red ferocious qi poured into the star flag, and the bone essence turned into powder, constantly blessing the star flag.

Some of the rifts in the Star Banner are healing rapidly, and the aura of the Star Banner is constantly improving.

The level of the primeval beast is too high, and the ascension of the star banner is obvious, more than 10,000 star flags continue to vibrate, exuding bursts of joy, and the power of the stars forms a small whirlpool, absorbing the essence of the beast's bones like a whale swallowing a cow.

In less than a day, the mana of more than 10,000 Star Banners had all recovered as before, the scars had already healed, and the aura was still improving rapidly.

At this time, the murderer's broken arm was only consumed a small part.

Lin Yi's spirit was greatly lifted, his eyebrows brightened, and he mobilized the purple microstars in the sky, and his divine consciousness was strengthened again, increasing the absorption speed of the star flag.

......

Day and night alternate, the sun and the moon are reincarnated.

In the blink of an eye, another fifteen days have passed, and at this time, there is only half a month left before the Demon Punishment Battlefield reopens.

On this day, Lin Yi sat cross-legged in the deep pit of the Yantian Great Array, his eyes flashed between opening and closing, his sword intent was awe-inspiring, and a smile of relief appeared at the corner of his mouth.

In front of him, the severed arm of the primeval beast had disappeared, and only more than 10,000 star flags slowly rotated, with brilliant starlight and a strong breath.

The level of each Star Banner is not weaker than that of ordinary Dan weapons!

Originally, it was just a ground-level spiritual weapon, but after this sacrifice, all of them were promoted to become Dan weapons!

More than 10,000 pieces of Dan weapons, even without any formation, smashed overwhelmingly at the Yuanying Great Cultivator, and the latter was extremely difficult to resist.

If it is under the blessing of Zhou Tian Star Dou Great Array, the power of the formation is enough to shock the world and become Lin Yi's biggest killer!
