There was a earth shattering sound just like a clap of thunder. The brilliant light was like 10,000 golden swords that shot out in all directions. Countless rocks were sent scattering into the air!The arena had turned into a giant pit. The arm that the Witch Slave had raised was now completely broken, and blood spewed from it like an endless crimson fountain.It cried out with a muffled roar, its enormous body trembling. Its chest was soaked with blood even as more blood sputtered out endlessly from its body.“It’s still alive?” Lin Ming was shocked. This was definitely the most durable being that he had ever encountered so far.“Die!”Lin Ming’s feet tread the ground and his body flew forth like an arrow. Under the effects of Golden Roc Shattering the Void, Lin Ming’s speed had reached the pinnacle!Puff!The spear pierced into the wound on the Witch Slave’s chest that had been opened by the Thunderfire Annihilation attack. The spear finally managed to break through the torn flesh, Flow like Silk erupted within the monster and rushed towards the heart of the Witch Slave. With a new injury added to the old, the Witch Slave gave one final roar as it unwillingly went down.Its corpse rapidly dissolved, turning into a green energy that poured into Lin Ming’s body.“Mm… this energy is…”Lin Ming felt that the green energy was extremely oppressive and tyrannical. Before, whether it was the energy of blood vitality from the blood demon or the soul force from the hungry ghost, or even the vicious beast’s energy that was able to transform the strength of a human’s body, it was all very gently and effortlessly absorbed.But this green energy was extremely savage. It brutally rampaged through his body, and sent waves of agonizing pain rolling through its path. Lin Ming’s forehead began to drip with large beads of sweat.Dense crackling sounds resounding within his body, as if the bones of his skeleton were striking each other. Hearing this, even Lin Ming was feeling a bit fearful.At this moment, the space in front of Lin Ming began to distort, and Yan Mo appeared.Yan Mo looked at Lin Ming and said without any emotion, “Congratulations. In this smelting trial, you are the first martial artist in the last 6,000 years to pass the trial of the Witch Slave.“You do not need to fear. This energy has simply been saved up for too long; a full six millennia of time. Therefore, it is a bit overbearing. It will only transform your body; it will not bring you harm.”“Six… six millennia?” Lin Ming found it difficult to speak through the pain.“Yes. 6,000 years ago there was a man named Qin Yu that was able to pass the fourth level of the smelting trial. However, he was defeated in the fifth level, the Mortal trial. After he went back, he founded a vast empire in the Southern Wilderness, and was called the Feather Emperor by the people of the South.”Right… so it had already been 6,000 years since someone managed to pass through the Witch Slave trial. This wasn’t too surprising. It was only because he had accidently comprehended the Thunderfire Annihilation skill that he would have such an abnormal striking power. A normal martial artist would never be able to get past the freakish defensive capabilities of the Witch Slave.Slowly, Lin Ming found that the green energy had fused into his skeleton. His skeleton had become denser, and his muscles had become tougher.The physical defense had experienced a crazy increase in power.Before now, Lin Ming’s body strength was formidable. However, that did not mean that his defensive power was similarly formidable.For instance, an iron armored cow could easily break steel plate, and if a sharp axe were to fall on their body, it wouldn’t leave any damage.If Lin Ming wanted to fend off a sword with just his bare hand, he could only rely upon his Flow like Silk technique to vibrate the weapon and send it flying away. If his fist really did meet the blade of a sword, then his hand would simply be split in two.But now, Lin Ming had absorbed the green energy which had augmented his body, and he felt his body grow more solid, and his defensive capabilities increased. Now if he faced a martial artist on the level of Zhang Cang, Lin Ming believed that he wouldn’t even need to use true essence; he could simply use his own bare hand to stop the other’s attacks.As Lin Ming unceasingly integrated with the green energy, the aching pain he felt gradually weakened. Lin Ming’s entire body was covered in sweat, and mixed within the sweat were black, oily drops. These were clearly the impurities that were in Lin Ming’s body.In the past, Lin Ming had taken the Golden Deer Pills to temper his body. However, that was only the lowest level of medicine used to temper one’s body; it naturally wasn’t able to be compared to something so fantastic like this green energy.After his muscles and marrows were purified, Lin Ming collapsed to the ground.Yan Mo said, “After passing the fourth trial, from here on out, you will have three hours
