The iron sword is psychic, and Su Yu has known it for a long time.

And at the moment it shook so violently, it was obvious that it had discovered something.

Su Fu's heart moved slightly, and he directly took out the iron sword, but before he could look at the iron sword, the iron sword had already come out of his hand, turning into a streamer and roaring towards the thunder sea in front of him, like a fish entering the sea, rampant in the thunder sea.

Su Yan's figure immediately swept out, chasing after the iron sword, and a look of surprise appeared in his eyes.

But at the moment when Su Defeat's front feet just stepped out of the stone platform, there were countless blood-colored thunderbolts roaring, like an angry dragon, opening its teeth and dancing claws, and crashing down on Su Defeat's body, that terrible power frantically tore Su Defeat's body, the energy contained in these thunders was more than ten times that of the Sixth Heaven, Rao was Su Defeat had already prepared, but he still couldn't help but gasp.

It hurts!

However, the effect of physical body refining is also obvious, Su Yu can sense that the energy contained in these thunders is gradually integrating into his physical body, constantly washing and refining, and even gradually integrating into his blood, making his entire body echo with thunder all the time.

The speed of the iron sword is very fast, but with Su Yu's current strength, it is easy to catch up and follow.

Baizhang... Thousands of feet... Million...

Su Yu didn't know if he was already close to the depths of the Thunder Sea, the thunder here was more dense and blood-red, it was completely a blood-red world, and the incomparably strange thunderbolts dragged out dazzling light and landed on him, his whole body was already blurred, bloodstained, but his eyes were full of energy.

Sonor!

With a sword roar, the iron sword in front of him suddenly stopped.

Su Yu raised his eyes sharply and looked over, this look, his pupils shrank suddenly, and the unconcealable excitement surged out on his face, only to see that in the area more than 100 zhang away, a bleak blood-colored demon lotus was slowly blooming, and the ethereal Sanskrit sound continued to sound from within it, shaking the lotus leaves and moving, a total of five lotus leaves, each lotus leaf has a green glow flickering, such as a fairy rainbow flying, filled with a majestic breath of life, even if it is so far away, Su Yu can also detect the fragrance released when the lotus blooms.

"Five-grade thunder essence..."Su Yu had a feeling of hitting the jackpot, he heard Xuan Ku say, the thunder essence in the thunder pool is also graded, the ninth grade is the most, the first grade is the second, the thunder essence he saw in the sixth heaven is the fourth grade, obviously, the energy contained in the four-grade thunder essence is undoubtedly not as good as the five-grade thunder essence in front of him.

"Dude... I didn't expect you to have this ability. Su Wei looked at the iron sword suspended in mid-air, and walked over, but at this moment, the iron sword once again emitted a crisp sword sound, turning into a streamer of light and rushing towards the blood-colored demon lotus, Su Fu's heart was shocked, and he suddenly had a bad feeling.

Swish...

The cold sword blade bloomed with a dazzling cold light, piercing the sky like a falling star, cutting through the sea of thunder, and slamming down on the blood-colored demon lotus, half of the sword body directly submerged into the blood-colored demon lotus, and then, Su Yu saw that the blood-colored energy that originally flowed in the blood-colored demon lotus was converging towards the iron sword at an extremely terrifying speed, and the vitality that lingered around it was also dissipating at a very fast speed.

"Groove cake..."Su Luo's body moved, and he rushed out, he should have thought of this scene in front of him a long time ago, according to the previous style of the iron sword, how could he easily let go of the five-grade thunder essence in front of him, if he didn't hurry up, the energy in this five-grade thunder essence would probably be swallowed up by the iron sword.

The sword intent was agitated, the white sword qi turned into a storm and swept out, Su Yu broke through the thunder sea in front of him, and his figure appeared on the blood-colored demon lotus, looking at the iron sword that was close to Chi Qi, Su Yu immediately sat down cross-legged, and according to the refining method that Xuan Ku said at the beginning, he refined this five-grade thunder essence.

For a while, the blood-colored demon lotus was full of brilliance, turning into a pillar of light that soared into the sky, enveloping Su Defeat, in this pillar of light, the essence blood was like a flood, directly hitting Su Defeat's body, these blood was no longer pure demon saint blood, but combined with these thunders, after endless years of washing, the product of birth, which not only contains extremely violent thunder energy but also rich vitality.

In an instant, Su Fu only felt that a majestic energy was passing through his pores and entering all corners of his body, tearing apart his flesh and blood at an extremely crazy speed, and at the same time, repairing his physical body at a terrifying speed, which was a process of alternating destruction and rebirth, and his physical body was undergoing an astonishing transformation.

At the same time, streams of incomparably pure energy flowed through his limbs and bones, and Su Yu barely had much effort to refine it into his own sword yuan and merge it into the Purple Mansion.

What made Su Wei feel the most incredible was that when he sat on the blood-colored demon lotus, bursts of Sanskrit sounds continued to echo in his ears, making his state of mind calm and peaceful, making his cultivation state maintain an excellent state.

"Xuan Ku is not exaggerating... The refining effect of this physical body is indeed a hundred times greater than that of ordinary cultivation, no wonder the group of people before fought for the thunder essence. Su Wei muttered, but there was a burst of heat in his heart, his cultivation has reached a bottleneck now, and now there are only two paths in front of him, one is either to continue to break through himself and promote to the Nine Extremes Royal Dao, or to comprehend the sword momentum and promote to the Imperial Dao Realm.

The Nine Extremes Royal Road, that means the true limit of the Royal Road Extreme Realm.

"If there is a steady stream of thunder spirits... Then maybe I might be able to take that step..."

"Just the first step of the reincarnation immortal sword body will allow me to advance to the Eight Extremes Royal Dao..."

"The three hundred and sixty-five Sword Pond Cave Heaven has been completed, and now it is the Fourteen Sword Meridian Wonder Veins... It's time to try the second step of the Reincarnation Immortal Sword Body..."

Su Yu's eyes were slightly closed, and the obscure fluctuations of ancient vicissitudes spread in his blood, turning into wisps of light and converging towards his Purple Mansion, and in his Purple Mansion, it gathered into a sword shadow, revealing a peerless edge, which was a divine channel pattern that belonged to the reincarnation immortal sword body.

"The hand is too yin... Hand Yang Ming... Foot Yang Ming... Foot too yin..."

The position of the Fourteen Wonder Sutras flashed in Su Yu's mind, if he practiced the Fourteen Sword Sutra Wonders, he would definitely not be able to do it overnight, but to cultivate them one by one, what he had to do now was to choose one of them first, he thought about it, or chose the Hand Taiyin, the Hand Taiyin Meridian is located in his left and right arms, if the cultivation is successful, then his arms will undoubtedly be tempered and strengthened again, then for his swordsmanship, there will also be a great improvement.

Thinking of this, Su Yu immediately began the cultivation of the reincarnation immortal sword body.

For a moment, the majestic and majestic essence blood energy converged towards his arms......
