"Boom!"

The Ancient Tower of Demon Alchemy, in the dark and deep world, purple and black gas, staggered, the collision between the bronze ancient sword and the divine axe produced a deafening huge roar, and between the spread of the qi waves, a figure fell out like a broken kite, rolling on the devastated ground, shattering countless green bricks, and dragging a dilapidated ravine on the ground.

It was Lu Yang who was no match for the Tiger King, and was used by the Tiger King to shake the power of Kunlun, and he fell and flew dozens of feet away with an axe, seeing that his breath was already dying, leaving only the purple brilliance of the gossamer that was still spreading above Lu Yang's body, soothing the pain of the battle for him.

Time is like water, seven days have passed, and Lu Yang is facing cruel battles every day in addition to refining skin and quenching bones in the starry sky refining fire. Whether it is the Evil King, the Python King, or the Tiger King, when refining Lu Yang's cultivation, he is ruthless and stimulates his growth with real battles. Although he spent every day in an intense cultivation, his cultivation was already constantly approaching the peak of the Xuandan Realm unconsciously, and the Xuandan in his body was constantly accumulating energy in order to advance and surpass the limit.

Fighting with all his might is often the best way to improve his strength, although he was beaten and scarred under the iron fist of the Tiger King, but he often competed with the Tiger King at the same time, the strength in his body was also growing. came to compete with the Tiger King's strong body, and over time, Lu Yang's control of the destructive power in the desolate veins became more perfect.

The Seven Ancestral Souls blessed in the bronze ancient sword are the Seven Ancestors of the Flood Desolation, and at the last moment when the Flood Desolation is about to collapse, the Seven Ancestors took the ancient desolate veins buried in the earth, and burned all the cultivation of the Seven People Reincarnation Realm together, turning into the Seven Immortal Sword Souls and blessing them in the ancient sword. This makes this Excalibur the most powerful divine weapon.

However, the secrets of outsiders' inability to control the bronze ancient sword all came from the desolate veins in Lu Yang's body. The desolate vein has taken root in Lu Yang's body, and only Lu Yang can communicate with the power of the Seven Ancestors and arbitrarily use the power of the desolate vein.

Lu Yang's strength is steady and steady, gradually improving, his progress Tiger King is in his eyes, from the time Lu Yang just came to the second floor of the ancient tower to now, he has been able to hold on to a quarter of an hour under the Tiger King's divine axe. In particular, Lu Yang's strength entered the realm extremely large, and the Tiger King gave Lu Yang all the elixir and divine herbs he had stored when he was in Kunlun. The strange immortal elixirs that were born in the bitter cold realm of Kunlun Mountain made Lu Yang's cultivation more and more rapid.

"At present, your strength has stabilized at the middle stage of the Xuandan Realm, which is a very good cultivation speed. The Tiger King took out a crystal ball and tested his cultivation for Lu Yang, and found that his strength was getting stronger and stronger, before coming to this ancient tower, Lu Yang had only initially stepped into the Xuandan Realm, but this was only a little more than a month, and he was able to completely stabilize his cultivation, and he continued to break through.

"Is it in the middle of the Xuandan Realm...... I must quickly touch the threshold of the Xuanyin Realm. Lu Yang nodded, although the speed of progress was already terrifying, he was still a little anxious in his heart, he was unwilling to let go of any opportunity that could make him strong.

"Haha, there is nothing wrong with young people eager to become strong, but don't remember not to be impetuous, the path of cultivation is always a move against the current, if you don't advance, you will retreat, if you are too attached to strength, then there will be flaws and go astray. The Tiger King smiled and said to Lu Yang: "Xuandan Realm, Fire Refining Jade Pass, this is only the first calamity of cultivators. However, the further you go, the more difficult your cultivation becomes, and compared to your current ascension speed, this king hopes that you will continue to suppress your cultivation before the Xuanyin Realm. ”

"Dare to ask the Tiger King's seniors, why is this?" Lu Yang was a little puzzled and asked the Tiger King.

"It's very simple, breaking through the level and entering the Xuanyin Realm is extremely dangerous, only by making all the preparations can you survive the catastrophe unharmed. When you reach the threshold of the Xuanyin Realm, you must connect with the extreme yin qi between heaven and earth, refine the Xuandan, and make the Xuandan further evolve. The cultivators called this step the calamity the Yin Refining Pill. ”

"As we all know, if the yin is cold and cold, if the cultivation is vain and uncertain, it is not enough to control the Yin Qi to refine the Xuandan, then the Yin Qi will phagocytose the body, walk into the hands and feet of the three yang meridians, completely cut off their own vitality and die a miserable death. ”

Lu Yang couldn't help but shudder, no wonder the monks in Zhongzhou joined the sect when they decided to cultivate the path and seek immortals, practice the true law under the guidance of famous teachers, and condense the vitality of heaven and earth. This path of monasticism is indeed a dangerous one. If he Lu Yang didn't have the guidance of the Tiger King, then it would definitely be difficult to resist the temptation of power and break through the gate of the Xuanyin Realm in one fell swoop, and at that time, maybe he would fall into a situation from which he could never recover.

"And your situation is even more special. This king knows that the 'Nine Turning Heavenly Pill' in your body has given you a powerful talent and a powerful mana that far surpasses that of other monks. However, it makes your cultivation path even more dangerous. The Tiger King obviously discovered the problem in Lu Yang's body, Zhengse said.

"Yes. Lu Yang nodded truthfully and distressedly, when he stepped into the Xuandan Realm, there was this problem. It's just that the 'Nine Turns Heavenly Pill' grade in his body is really extraordinary, and the flames in the mortal world can't complete the refining of the Xuandan in his body at all. If it weren't for the calcination of the Eight Desolation Divine Flames in the Purple Dragon Domain, which caused the Heavenly Pill in his body to evolve, I'm afraid this problem would have bothered Lu Yang for a long time. And now again, this question is also coming one after another.

"Although you are the body of the Ziya Divine Stone, immortal and immortal, but if you want to find a powerful Yin Qi to meet the evolution of your Heavenly Pill, how difficult it is, if the ordinary Xuandan Realm is exhausted, you only need to be in the place of Shanyin, sneaking and cultivating. But you are different, the power of the Heavenly Pill is countless times that of the Xuandan of the Human Realm, and at the same time, it also needs the most powerful Yin Qi to temper it. ”

"Hey. If I can't meet the needs of Tiandan's evolution, then I won't have great power. So, I'm going to do whatever it takes to make myself stronger. Lu Yang understands that the source of becoming powerful is destined to pay many times more than ordinary people, but he is not afraid, because he himself has the most powerful and tenacious heart.

The Tiger King raised his head and smiled, and said, "This king knows a realm that is more suitable for you to break through the Xuanyin Realm in the future, but it is a place full of dangers. It is located on the top floor of the Seventy-Two Ghost Domains, close to the Human Realm. But it is a place of death in the legends of your human world, and it is the place where the strongest evil aura in the world is gathered. ”

"Where is that?" Lu Yang's eyes lit up and he asked happily.

"It is the Lethe River in the Yellow Spring Domain of the Ghost Realm, a thousand miles of Lethe River, where countless fierce spirits and wild ghosts wander, and the reincarnated beings who cross the Lethe River above are just like the difference between heaven and hell. The Lethe River can contain hundreds of millions of evil spirits, which shows how powerful the evil aura in it is, even if the king has recovered his peak cultivation, he does not dare to go deep into the bottom of the Lethe River to find out. The Tiger King grinned and said.

"Lethe River ......" Lu Yang couldn't help but feel creepy, it turned out that there really was a legendary realm, and it was said that the people who were reincarnated in the Netherworld Ghost Realm completely bid farewell to everything in their previous life after stepping on the Nahe Bridge on the river. On the other side of the bridge, there will be an ugly wife, she is called Meng Po, and if every reincarnated person drinks her Meng Po soup, they will forget the past and be reborn as a human through the ancient path of reincarnation.

When they were young, many children were afraid of this story, fearing that one day, they would leave this world and never see their relatives again. Birth, old age, sickness and death, people are rotating day and night all their lives, and when they look back on the Lechuan Bridge and drink the bitter Meng Po soup, those who can't let go will eventually return to the bright moon of the loess and disappear.

Lu Yang secretly wrote down the boundary indicated by the Tiger King, and he was put into this place by the gods from the Purple Dragon Domain as the 'Well of Crossing the Boundary'. I don't know which region is outside this Demon Refining Tower. But the experience of the Tiger King told him that the ghost realm has a vast area of seventy-two mysteries, but the ghost realm belongs to the mystical realm and lives under the human realm. If you want to escape back to the human realm here, you must go up, find the door of space that connects every domain in the ghost world, and finally return to the human world through the hell gate that opened outside the Black Moon City hundreds of years ago.

However, the Lechuan River pointed out by the Tiger King is located in the upper layer of the Netherworld Ghost Realm, and it is an important area of the Ghost Realm. Before Lu Yang escapes back to the human realm, he must first find a way to go to the bank of the Lechuan River, absorb the evil qi and enter the level of the Xuanyin realm, and then find the exit of the gate of hell that connects the human realm, so as to completely stay away from the dark ghost realm.

"The yin and evil qi that has accumulated in the Lechuan River for thousands of years is not so easy to absorb. Before that, your cultivation must reach the point of incomparably condensed, according to the experience of this king, after you break through to the peak of the Xuandan realm, you must first compress and condense your cultivation more than nine times before you can withstand the invasion of the Yin Qi of the Lechuan River, so you still have to continue to cultivate hard!"

Lu Yang gritted his teeth, it seems that his road is destined to be full of bumps and thorns. However, he can turn the pressure and burden on his shoulders into strength, no matter how many difficulties and dangers lie ahead, he must also surpass the limit again and again, and be reborn in Nirvana.

The desolate veins in his palms surged, and he held the bronze ancient sword horizontally in his hand, and looked up at the blood-colored moonlight outside the window of the ancient tower. He must rise again in the dark purgatory, and at that time, even if it is the memory lost ten thousand years ago, it will still be the beauty of the separation of heaven and earth. He had to get it back personally, no matter how hard it tried.
