The City of Light is a barren and remnant ruin, like a huge mound, I don't know how many stories have been buried, and it has been ruthlessly swallowed up by the years.

Most of the building materials in the city have collapsed, and long cracks have cracked in the ground, although it has become very natural after countless years of precipitation, but at a glance, it still looks like a ruthless monster with its bloody mouth open, as if it is devouring life at any time, showing its hideous face.

On top of the dusty ruins, there are some red and black vegetation coiled, and in the open space there are some strange plants and trees that look like swords, one after another, I don't know how many years they have grown, and they are tall enough to be human. At the edge of these plants and trees, there is a small mud pool, and the aquatic plants in the mud pool are like big trees, and clusters of them are sticking out of the water.

Recalling the strange black vines from earlier, Tang Bai was very careful and wary of these vegetation.

Sure enough, he didn't go far, he saw some mutilated bones in some dense vegetation, some people have beasts, mutilated, as if after the baptism of the years, the bones have become more white, white and infiltrating. In a trance, it makes people feel as if all living beings are living in the grave of time, rotting and turning into dry bones in the course of time.

This is a ruined city full of alien vitality, monotonous red plants and black vines are entangled, as if the cold silence after prosperity, exuding a desperate atmosphere.

Tang Bai took a deep breath, endured the pain in his body, and moved his steps carefully, he felt that there was a strange qi in this bright city, condensing but not dispersing, gathering but not letting go.

He opened his eye of perspective, and everything in the city was broken down into particles of different colors, and he found that there were many strange energies in the sky around him, which were extremely chaotic, but mixed together, forming a peculiar magnetic field, forming a circular gap in the center of the city, like a huge ring, enveloping the city that had been abandoned for an unknown number of years.

In the central square of the city, there is a building like a tower, on which there is a huge rune shaped like the character 'ten', and from a distance, there seems to be a faint light flickering on the ten character inscription.

Tang Bai was stunned, his heart moved slightly, and he said secretly: "Is there still a formation in this city?"

Seeing that the sky was getting dark, Tang Bai walked along the path he had chosen, although he was frightened along the way, carefully calculating the safety of every step, but after going around and around, he finally walked to the city square and looked up at the tower in the square.

The square is a big football field, and the square is paved with white floor tiles like jade, without any vegetation on it, let alone any living creatures, not even dust, as if for countless years, someone has been constantly scrubbing, so that this square remains as clean as jade.

The tower is very well preserved, there are seven floors, divided into octagonal, with white stone as bricks, glazed as tiles, the white stone is carved with patterns that seem to be words and charms, gradually shrinking from the bottom to the top, shaped like a cone; the ten-character text on the top of the tower is full of extremely strange energy.

The square tower, the perfect fusion in the rise.

Tang Bai did not feel the danger of the square, on the contrary, he felt an alternative vitality from the ten-character inscription on the top of the tower. This vitality is different from the vigorous vitality emanating from the creatures of plants and trees, and it seems to be a very special and pure substance.

Tang Bai hesitated for a moment, and finally stepped forward with his feet open.

In a trance, he felt that the ten-character inscription on the spire flashed, and then the pattern on the white stone seemed to become brighter, and the space on the square suddenly became heavy, as if a force of hundreds of catties suddenly pressed on his body, causing the injuries in his body, making him feel that his body was as painful as being torn, and then he faintly felt that the rules here were a little different from the rules outside.

Tang Bai didn't expect that it was just one step away, but it was like stepping into two worlds.

He gritted his teeth, endured the pain in his body, and took three more steps forward.

He only felt that every step he took, the gravity on his body was superimposed, as if he was pressing a boulder weighing a thousand pounds on his body, but his mind was very clear, like a clear spring, washing his soul, making his heart pure, his thoughts were clear, and his wisdom was sublimated.

So, Tang Bai ran the Witch Body Dafa and took five steps in a row. He wanted to see how gravity would reach here, and what the rules would be.

The invisible force became heavier and heavier, as if the air particles had turned into iron beads, and the gravity from all directions pressed on Tang Bai's body, making him feel as if he had entered the depths of the earth, bearing the squeeze of the earth's force, and the 'lotus seeds' of his dantian, the two words of 'blood and yin', exuding blood and yin, were introduced into all parts of his body, and with the operation of the witch body Dafa, it was actually repairing his body.

This is actually an excellent place to practice the Dafa of the Witch Body.

But under the influence of the rules here, the bloody and yin qi of his sea began to spread wildly, constantly shaking his mind and will, wanting to control his heart, control his mind, and turn him into a walking corpse-like evil demon.

In this square, although Tang Bai had the confidence to cultivate his physique to be more powerful, he couldn't control the evil thoughts of Zhihai at all.

The rules here are like an invisible magnifying glass, infinitely magnifying all tangible and invisible forces.

In just the blink of an eye, Tang Bai's temperament has changed, becoming very cold, without any emotion, his whole body exudes a violent and ruthless aura, and even the emptiness around him seems to have become cold; at the same time, his eyes have become blood-red, and even his pupils are like two red gems, exuding a strange evil light.

Tang Bai hurriedly said badly, after he originally practiced the "Nine Yang Sutra", he cultivated the idea of awakening the heart of a yang in the sea of knowledge, but he could not be confused, although he could not suppress the two evil qi in the sea of knowledge, but at least he could maintain a balance.

But in the previous battle, the thought of a yang was consumed and swallowed by the Buddha in the wood carving, and at this time it was difficult to control the heart, and it was impossible to suppress the evil thoughts in the sea of consciousness.

Just when his mind was about to be controlled by the two evil qi, Tang Bai bit the tip of his tongue, kept awake with the pain of drilling his heart, hurriedly took out a porcelain bottle from the purple gold ring, poured a green pill from it, and took it in one mouth;

He breathed a sigh of relief, in this kind of crisis, he needed to keep his mind clear, and he must not be accused of being demonized.

He decisively exited this strange white stone square, and then desperately consumed his spiritual power, opened the eye of perspective, and found a safe and relatively well-preserved room in the ruins.

There were still some relatively complete stone tools in the house, I don't know how long they had been placed, and they were covered with thick dust, but at this time, he didn't rush to take a closer look, and with a wave of his hand, the true yuan surged, like an invisible tornado, rolling up all the collapsed gravel and dust, and throwing them into the courtyard wall outside the house, clearing out a small open space. Then he sat quietly cross-legged, took the cracked wood carving from the purple gold ring, and studied the "Nine Yang Sutra" again, and then calmed down and began to practice.

This practice lasted for seven days, and Tang Bai seemed to turn into a stone sculpture, motionless, but his temperament was changing, and the Buddha rhyme on his body was increasing day by day, and he was slowly transforming from a person full of evil qi to a monk who was dedicated to chanting sutras and doing good.

At the same time, the 'lotus seeds' of his dantian were slowly absorbing the vitality around him, not only making up for the consumption required by his body, but also slowly repairing the injuries in his body.

More than a month has passed, the weather seems to have become hotter, and Tang Bai has become a Buddha with compassion and compassion for all sentient beings.

Tang Bai quietly realized the meaning of the Yang Thought, and he felt that as long as there was an opportunity, the Yang Thought could be like the rising sun breaking through the darkness, emitting infinite light and heat, and exuding the true Yang meaning.

Tang Bai stopped practicing, and he didn't find an opportunity to break through.

But he did not get up, but continued to sit cross-legged on the ground, quietly feeling the peace of mind.

If the heart is not self-deluded, it must be undisturbed by external objects, so that the realm of one yang can be successfully cultivated, and then the intention of the yang to protect the heart, you can resist many yin and evil spirits, not controlled by it, and lose yourself.

Tang Bai also knew that Yiyang Awakening Heart made rapid progress at the beginning, but eventually it would take a drop of water to practice like a stone to truly achieve success; this reminded him of the realm of a craftsman in secular martial arts, and the two practices were compatible; it seemed to be the cornerstone of a high-rise building, and the more solid the cornerstone, the stronger the future achievements would be.

After another pillar of incense, Tang Bai waved his hand, and suddenly a lot of things appeared on the ground, including the charms he bought from the Yin Spirit Mountain Range, pills, magic weapons, polished rice issued by the Great Yan Sect, cultivation exercises, spars, and various loot from others, all of which appeared in this small house. He sorted some of the commonly used things into categories and put them in his ring, and all that was left on the ground was a jade carving, a black vine, a wood carving, a rope, a shield, and a purple-gold cloth bag.

He looked at Yu Zhuo and shook his head gently, this was originally a magic weapon obtained from the Great Yan Pagoda, but he didn't know how to refine it. Xiang Lao once said that the sacrificial practice can be divided into sacrifice and refining, the sacrifice is guided by blood, paid with sincerity, and the sacrificed things are spiritual, and for a long time, in order to achieve the method of controlling the matter at will and using the thing for oneself, but these are relatively low-level magic weapons.

He had read the detailed explanations of cultivation and knew that many magic weapons, pill weapons, or higher-level artifacts were engraved with unique rune formations, and these artifacts needed to be refined by themselves if they wanted to use them for their own use. This is also a refining within a sacrifice.

It's a pity that not only is his cultivation time short, but he is also a dispensable ordinary disciple in the Great Yan Sect, and he doesn't know the method of refining at all.

He sighed, reluctantly put the jade into the purple gold ring, and then picked up the black vine.

This black vine is about a length of one or two zhang, and it is wrapped together in circles, like a black rope, and if you have not seen its power, you will feel no different from the rattan in some mountains and fields when you touch it.

Tang Bai hesitated for a while, but still bit off the index finger of the lieutenant general, and tried to drop a drop of blood on the black vine, only to see that as soon as the blood fell on it, it was instantly absorbed by the black vine.

He couldn't help but let out a soft 'huh', looking a little surprised.

At first, he didn't think that this black vine was a magic weapon, but he saw that it was once extremely powerful, so he picked it up, and at this time, it seemed that it might be a surprise.

He calmed down, and after another drop of blood, and after being absorbed by the black vine, he finally fell into a smile, as long as he could sacrifice, maybe there would be another means to save his life in the future, and he happily included the rattan in the purple gold ring, because the sacrifice is not a matter of one or two days, but it takes a long time to succeed.

Then he tried wood carving, ropes, and shields, but all of them were unsuccessful, until at last the blood dripped on the purple-gold cloth bag, and the blood was instantly absorbed by the cloth bag, and he laughed, and finally had another surprise.
