Lin Chuan's qualifications are not good, and it is already difficult to break through the realm, and he has already had the experience of failing to break through the realm once, so the difficulty of breaking through the realm has increased a lot this time.

Even with the assistance of precious elixirs such as the Tiger Bone Pill, the Transformation Spirit Pill, and the Meditation Pill Pill, Lin Chuan's chances of breaking through the realm were not very high.

However, in the end, Lin Chuan relied on his tenacious will to force the power in his body into the dantian, and in this short period of time, Lin Chuan seemed to have suffered a thousand tortures.

With the strength of his physical body, his body was shaken by the sudden burst of terrifying power, and blood flowed out along the cracks, dyeing Lin Chuan into a bloody man.

And fortunately, he had an extraordinary body, and the medicinal power of the tiger bone pill protected his body, so he survived, otherwise he would have died just now.

And at this moment, a huge force entered the dantian, and the mana vortex was like a hungry beast, and the suction power rose, and the power that poured into the dantian was rolled up, and all of them were pulled into the mana vortex.

I saw that the color of the swirling mana vortex had deepened a lot, and the aura emitted had doubled, and the speed of the rotation had also doubled.

The mana vortex continued to rotate at high speed, and I don't know how long it took, but finally the mana in the center of the vortex condensed towards the center, and a drop of liquid appeared.

Although it is just a drop of liquid, it contains pure mana, which is completely made of mana, this time it is not like last time, after this drop of liquid is condensed, it falls into the dantian.

The first drop of liquid condensed, followed by the second, the third, and the fourth...... , more and more mana condensed into liquid, and the liquid mana in the dantian gathered more and more.

The whirlpool is gradually shrinking, and the mana contained in it is rapidly turning into liquid, Lin Chuan, who is concerned about the situation in the dantian, finally breathes a sigh of relief, and finally breaks through to the middle stage of foundation building, and the spirit gathering liquid is the mark of the middle stage of foundation building.

At the moment when Lin Chuan broke through, a huge suction force came from his dantian, and the suction spread in all directions, and the spiritual energy in the stone room and around it was attracted and began to gather towards Lin Chuan's side.

At first, only the aura in the stone chamber was attracted, but as time passed, the aura outside the stone chamber was also pulled.

Under the pull of this powerful suction, with Lin Chuan as the center, the aura within a radius of hundreds of zhang was pulled over, all forming bands of aura light and drilling into Lin Chuan's body.

As the body was surrounded by aura, these auras quickly merged into Lin Chuan's body, part of the aura ran along the meridians and converged towards the dantian, and the other part of the aura was directly integrated into Lin Chuan's body, beginning to strengthen Lin Chuan's body.

The wounds on the body were restored at a speed visible to the naked eye, and the damaged meridians became tougher and wider after being nourished by the aura.

After the musculoskeletal body was infused with a large amount of aura, it was full of vitality, especially the bones seemed to have grown in a circle and became harder.

The mana in the dantian gathered more and more, and after the mana gathered, it was transformed into liquid, at the beginning the liquid was only a small lump, and as time passed, the liquid became more and more, and gradually condensed into a pool.

The aura emanating from Lin Chuan's body is also rising, more than ten times stronger than in the early stage of foundation building, Lin Chuan's strength is very strong, and after breaking through to the middle stage of foundation building at this time, his mana is strong, far exceeding that of monks of the same level.

And when Lin Chuan broke through, due to his body's breakthrough to absorb the aura, a vortex of aura appeared in the air above the cave, and the nearby aura was attracted and converged to this side, so the movement also attracted the attention of some monks who entered the secret realm of the sea.

A few miles away from the Lin Chuan Cave Mansion, three monks in black robes with hideous faces were cleaning up the two corpses on the ground and looting out the contents of the two corpses.

"Hehe, this secret realm of the sea is really a good place, instead of collecting genius treasures by yourself, it is better to be such a hunter" One of the black-robed monks smiled, picking up a flying sword not far away, and after checking it with satisfaction, put it into the storage bag.

"Second brother is wise, with the strength of our three brothers, in this secret realm of the sea, as long as we don't encounter that kind of powerful late-stage foundation building monks, or groups of sect monks, it is enough to make a windfall, it is much easier than collecting genius earth treasures," said another black-robed monk who was squatting on the ground

"Hehe, it's still because of the eldest brother's presence, the strength of the eldest brother is much stronger than that of ordinary mid-stage foundation building monks, plus the two of us, and which mid-stage foundation building monk is our opponent, then we just need to be careful, avoid those sect monks and demon beasts in the secret realm, it will definitely be fine" The second black-robed elder smiled and said

"Hmph, this is the secret realm of the sea, it's not a good place, let's be careful" The other person's breath was calm, and he should be the eldest of the three.

"Hey, there are aura fluctuations, could it be that some genius earth treasure was born!" Suddenly, the eldest of the three raised his head, looked in one direction, and let out a surprise with a contemplative look on his face.

The other two also raised their heads, with excitement on their faces, "The genius earth treasure that can cause such aura fluctuations must not be simple, this sea secret realm is really a treasure land."

"Let's go, let's go over and take a look, we must not let this treasure fall into the hands of others" The boss waved his hand, and his body shook and rushed out, and the two people behind him also followed.

In the stone room, Lin Chuan was refining the aura, and the injuries on his body had been completely healed, I don't know how long it took, the dantian stopped absorbing mana, and the size of the mana vortex was less than one-tenth of the previous size, and most of them had been transformed into liquid and precipitated in the dantian.

Standing up, Lin Chuan moved his muscles and bones, and suddenly there was a 'crackling' sound like fried beans all over his body.

The right hand punched several punches into the air in front of him, and a sharp fist wind rolled up, and then Lin Chuan's body shook, and instantly appeared on the edge of the wall, and his right hand punched at the hard stone wall.

Bang!

The wall shook, and a clear fist mark appeared on the wall, several inches deep, and there were fine cracks all over the side, with a smile on his face, Lin Chuan withdrew his fist with satisfaction, and his cultivation was promoted to the middle stage of foundation building, and even his physical body was greatly enhanced, and now Lin Chuan's strength is definitely not as simple as breaking through the middle stage of foundation building.

"The bottleneck has been broken, it's time to leave here to find an exit, I don't know how that brutal girl is now, with her strength, there shouldn't be any danger" At this time, Lin Chuan thought of Xiao Rao, who entered the secret realm of the sea with him.

Simply cleaned up, changed into a set of clean clothes, pushed open the stone door, Lin Chuan jumped out, and climbed upward, just when he was about to climb to the top, he suddenly sensed a dangerous aura, without saying a word, his body shook, flashing to the side.

Burst!

A sword light slashed at the position he had just been, leaving a deep sword mark, if Lin Chuan hadn't dodged quickly, I'm afraid this sword mark would have been on him.
