I submitted my mathematics to the country and won 500 million yuan

Li Zheng looked at the Chang'an City that was half prosperous and half in decline on the wall, and felt quite emotional in his heart. The Tang Dynasty was so powerful that even today, it is remembered by countless people in Daxia. But according to the words of the sages who left this underground palace, the decline of the Tang Dynasty is suspected to be related to darkness, which makes people want to uncover that layer of mystery.

He meditated slightly and realized that the mural in Chang'an City was a portal, and behind it should be a second stone room.

Li Zheng looked at the other three people. Zhou Ming, Zhu Zihang and Liao Qian obviously also discovered that Chang'an City was a door, and they all nodded to him.

Li Zheng did not hesitate. The ninth level of Qi refining was circulating, and an endless surging feeling spread in all directions. Then a roaring sound suddenly came, and the portal transformed into Chang'an City slowly opened along the dividing line between prosperity and defeat. .

Zhu Zihang glanced at Li Zheng in surprise, and Liao Qian also widened her eyes and exclaimed: "Classmate Li Zheng, are you the 9th level of Qi refining? How do I feel the same as my 9th level of Qi refining?" Not the same thing at all?”

Li Zheng smiled and said: "Good luck, the ninth link is relatively complete." After that, Li Zheng walked into the next stone room.

He didn't expect that he would subconsciously use the true energy of the Möbius strip. The power was no less powerful than the Great Perfection of Qi Refining, but it didn't matter. Anyway, it would be revealed to the public sooner or later in the practice exchange competition.

Zhu Zihang and Liao Qian followed closely, and they didn't ask too many questions. After all, Zhu Zihang had entered the True Essence Realm. No matter how strong a genius in the Qi Refining Stage was, he could only attract a little more attention at most.

Soon Zhou Ming also walked in, and stood not far from the entrance with Li Zheng and the others, looking at the second stone room.

The second stone chamber is still full of carvings, but this time it records an earth-shattering battle. At a glance, in the sky and on the ground, there are soldiers fighting in all directions, including those from the Tang Dynasty and those from the rebels. Each soldier's body was full of true energy, and he held the weapon in his hand and fought with all his strength.

Corpses continued to fall in the sky, and rivers of blood flowed on the ground. Li Zheng even vaguely saw the figure of a banished immortal and a sage in the sky. Behind those two figures, he even saw a man wearing a dragon robe. The figure, with a beautiful silhouette, is also fighting bloody battles on the front line. Around these figures, enemy troops fell to the ground in batches, and a circle of empty space was created around them. However, more enemy troops were still surrounding them from a distance.

Chang'an City, located in the center of the stone chamber, now combines Confucian righteousness, Taoist magic, Buddhist halo, and imperial power, forming a barrier that spans the world, guarding the last line of defense of Chang'an City.

Li Zheng's eyes quickly condensed, and he discovered that a blood-red crack appeared on the originally incomparably powerful barrier of Chang'an City. The source of this crack is a dark red beam of light that seems to come from hell. Li Zheng followed the light beam to find the source, and found that it turned out to be a blood-red scripture floating on the Big Wild Goose Pagoda.

The four of them, Li Zheng, all walked towards the carvings of Chang'an City. As soon as they stepped into Chang'an, they felt a vast aura coming from the blood-ink colored scripture. The entire city of Chang'an was filled with an aura of fear, and even the banished immortals, sages, emperors and beautiful figures in the sky revealed a sense of panic, followed by an irresistible despair.

Li Zheng, Zhou Ming and Liao Qian all looked at Zhu Zihang. Zhu Zihang nodded affirmatively and said: "This is the aura of the Great Perfection of the True Yuan Realm. It can't be wrong."

Li Zheng was shocked when he heard Zhu Zihang's affirmative answer. In ancient times in Daxia, or in other words, in ancient times around the world, no one could reach the True Yuan realm. This has long been the consensus of spiritual practice all over the world.

Even if there are one or two amazing talents who come into contact with the True Element Realm with their unique talents and unimaginable luck, due to the lack of acting deductions, the body will never be able to adapt to such intense power, or it will go wrong. If you become possessed by a demon, you will die young, or you will have no choice but to cut yourself off and fall into the mortal world.

But in the era when the Tang Dynasty was at its peak, a sutra carrying the power of the Great Perfection of the True Yuan Realm came out, which shattered the Chang'an City barrier with one blow, which was a fusion of the four peerless techniques of Confucianism, Taoism and Buddhism.

At this moment, the mystery that Chang'an City was breached during the war was finally revealed. At this moment, Li Zheng and the others stepped through the center of Chang'an City and passed the center line of the second stone chamber.

The carvings in all directions suddenly changed. The barrier of Chang'an City was completely shattered. The entire Chang'an City was torn into pieces. Blood spread and soon covered the entire city.

At a glance, Li Zheng saw that the sky and the earth were full of fleeing soldiers from the Tang Dynasty. Even the four figures crisscrossing the sky were flying away from Chang'an City with extreme reluctance.

Emotions of confusion and despair permeated the entire world. No one knew what that power was, and no one could understand why the city of Chang'an, which was so powerful that it was even invincible by manpower, was shattered like this.

Li Zheng could clearly feel the despair. The Tang Dynasty was so powerful in ancient times, but no matter how powerful it was, it was only a Qi-refining country. Regardless of the Great Perfection of Qi Refining or the banishment of immortals, saints and emperors, under the attack of power that spans an entire realm, all resistance is destined to be in vain.

Li Zheng looked at the Big Wild Goose Pagoda in Chang'an City again. The blood-ink colored scripture shattered Chang'an City with one blow and then disappeared.

He thought in his mind that the blood-ink colored scriptures came from the Big Wild Goose Pagoda, but the scriptures in the Big Wild Goose Pagoda were taken from the West a hundred years ago, and he couldn't help but feel a chill.

There is a force, disguised as the Bible of the West, dormant in the Big Wild Goose Pagoda for hundreds of years. When the Tang Dynasty reached its peak of power, it cooperated with a rebellion and shattered this glorious country that shone in ancient and modern times.

Li Zheng looked at Zhou Ming and the others. They did not communicate verbally, but they all understood in their hearts the meaning of the sage who left this underground palace, and there was shock in their eyes.

Is this the darkness the ancients called it?

In an era when the power of the True Yuan Realm should not exist on the earth, a destructive strike at the level of the Great Perfection of the True Yuan Realm was launched.

If darkness really exists, what kind of power will be the darkness that is about to come to this era?

The same true essence state and Dzogchen as it was thousands of years ago?

Or is it a true elixir realm that humans have yet to reach?

Li Zheng sighed and looked at the wall behind Chang'an City.

The carved murals on the ceiling, the floor, and the walls on both sides are all scenes of the Tang army being defeated and fleeing. These fleeing soldiers spread to the rear wall, and then stopped abruptly, leaving only darkness.

Li Zheng meditated silently and felt the Taoist meaning coming from this black wall. It was a long sigh:

The prosperous Chang'an is just a candlelight in the dark river. There is darkness in front of the river, and there is darkness behind the river. This candlelight will eventually return to darkness.

Yes, the candle in Chang'an finally went out today.
