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

In the skylight, Li Zheng felt the familiar fluctuations of the object-repelling technique, and after a few seconds, he moved to an unknown area. Then the light dissipated, leaving only darkness in front of him.

However, during the meditation, Zhou Ming, Zhu Zihang, and Liao Qian were all beside him, especially Zhu Zihang. His cultivation in the True Element Realm shone brightly during the meditation, like a big light bulb in the dark night.

Fortunately, Zhu Zihang took the initiative to throw out a lighting technique at this time, which immediately illuminated the surrounding environment. This was an underground passage paved with bluestone slabs, but the passage was filled with yellow-brown air. Li Zheng took a deep breath, and it seemed no different from ordinary air.

Li Zheng meditated for a moment and was suddenly a little surprised. He said, "It seems that there is a superposition of the excavated tunnel and the unexcavated rock and soil at the same time."

Zhou Ming also meditated for a while and added: "The boundary of the passage is perfectly integrated with the rock and soil, and the interior is in a superposition state. If it is explored from the outside, even the True Yuan Realm Dzogchen may bypass this underground passage."

Zhu Zihang nodded and followed: "There is also Zeno's turtle aura. Even if the earth is attacked with magic from the outside, unless the entire rock formation is shattered, all attacks will be reduced to zero speed to protect the integrity of the passage. "

Then Li Zheng and the other three began to deduce it individually and tried various small spells to see if they could cause a reaction in this ancient passage and trigger an unknown supporting magic circle.

Zhou Ming tried all the common methods of modern magic and then shook his head. He couldn't elicit a response, and he couldn't proceed to the next step of deduction.

Li Zheng also tried several small spells according to the magic circle guidance method mentioned in "Introduction to Spells", but nothing happened.

Zhu Zihang also condensed the performance formula out of thin air and derived a performance model of the underground passage, but he also had no way to start.

10 minutes later……

Zhu Zihang said: "Maybe this underground passage is just a simple passage. Let's rely on lighting technology and just go in and have a look."

Li Zheng and Zhou Ming both nodded and gave up the temptation.

Liao Qian watched the three people operating, and couldn't help but said: "Three big men from science and engineering, I think since this is the underground passage of ancient Chang'an, the thinking needs to be more artistic. We know that the ancient road rhyme of Chang'an was triggered twice, and once One is from the Sword Dance of Senior Li Yun, and the other is from the Feather Dress Dance, both of which are related to the prosperous Chang'an that has lasted for thousands of years. Do you want to consider making a poem about it?"

Li Zheng and Zhou Ming had dark expressions on their faces. They felt that what Liao Qian said was reasonable, but they did not dare to speak.

Zhu Zihang smiled and said, "Qian Qian, do you want to try?"

Liao Qian nodded and began to hum softly the song "The Colorful Feather Clothes". Her voice was very clear and graceful, and the tune she sang was very beautiful.

Li Zheng and the other two people all felt something. Liao Qian's humming really aroused a certain Taoist rhythm in the passage, and two rows of lights matching the true energy suddenly lit up on both sides of the passage.

Li Zheng immediately said: "Niubi, classmate Liao Qian is invincible."

Next, Zhu Zihang moved forward first, Liao Qian kept humming in the middle, and Li Zheng and Zhou Ming separated from the rear. Since ancient practice stopped at the Qi refining stage, among the four of them was Zhu Zihang, who had reached the True Yuan realm, so no one was too worried about the danger. Following the guidance of the lights, they soon arrived in front of an underground palace with a blank plaque on it.

The stone door of the underground palace was very thick. Zhu Zihang pushed it casually, and the majestic true energy poured in, and the stone door suddenly opened slowly. As the stone door opened, a Taoist rhyme came to several people. There was no sound, but it expressed the meaning: Descendants of Daxia, please drop your blood in the bowl.

Zhu Zihang hesitated for a moment, then lightly cut his fingertips, and dripped the blood from his fingertips into the stone bowl at the beginning of the stone gate according to Dao Yun's request.

The stone bowl suddenly emitted a burst of light, as if a formation had been triggered, and soon streams of light emerged, flying towards the stone palace, lighting up the entire underground palace. But at this time, the underground palace seemed a little hazy, obviously covered by magic, and one had to enter it to see the true face.

Another rhyme came, still conveying ancient thoughts:

Descendants of Daxia, after all, descendants of Daxia came here.

There are so many things we want to know, whether darkness has come, whether Daxia has safely passed through the darkness, or has it been completely enslaved by the darkness?

It's a pity that we don't know how many years have passed by this time.

Future generations, this is a tombstone that records the most glorious and glorious years of the Tang Dynasty, and also records the darkest and broken moments.

If the darkness still has not come, I hope that everything we leave behind can leave a trace of inspiration for you in the future generations.

If darkness has fallen, we can only leave our last wishes, children, good luck.

Dao Yun dissipated, and Li Zheng and the other four looked at each other, but did not speak for a while.

The coming darkness is a heavy stone weighing on the hearts of Li Zheng and Zhou Ming, and it is also one of Daxia's top secrets.

The two of them were able to access the dark secrets entirely because Zhou Ming released the controllable elixir-forming method at the end of his practice, and Professor Luo Yufei intervened personally, attracting the Ancient God Sect and also the emergence of myths. But whether the darkness is real or fake, and when it will come, are still core secrets that the two of them are currently unable to access.

As for Li Zheng and Zhou Ming, their contact is limited. Daxia practitioners, including Professor Luo, have not clearly affirmed or denied the existence of darkness, and many things can only be guessed.

Li Zheng didn't know whether Zhu Zihang and Zhu Zihang knew the existence of darkness, but judging from their reactions at this time, they probably knew something.

Li Zhengzheng broke the silence first: "Classmate Zhu Zihang, do you know what the ancients called darkness?"

Zhu Zihang hesitated and said: "Actually, there have been some rumors in the Imperial Capital, but they are all based on rumors. No matter what they are, let's go in and take a look."

After that, Zhu Zihang walked in first, and the other three did not hesitate, and followed closely behind.

After entering the stone palace, everything around it became clear. It was a stone chamber of nearly [-] square meters. The four walls, ceiling and floor of the stone chamber were all carved with patterns.

Li Zheng looked along the traces of carvings. They were pictures of the Tang Dynasty that were full of time. The patterns blended with each other. There was no clear dividing line, but there was a sense of the passage of time. From the reign of Zhenguan to the prosperous age of Kaiyuan, one bright star after another adorned it, and there were poems that the Tang Dynasty could never do without.

There are sunset clouds and solitary swans flying together, and the autumn water is the same color as the sky; there are sunsets in the countryside, and the misty waves on the river make people sad; there are also lonely sails in the distance, the shadows are gone in the blue sky, and only the Yangtze River can be seen flowing in the sky.

Countless patterns blended together, and finally came to the haunting Chang'an.

Chang'an City is made up of two pictures. One half is extremely prosperous and the stars are shining, while the other half is dilapidated and gloomy. At the same time, he left behind the last verse in the stone chamber: As time goes by, this hatred will last forever.

Li Zheng realized it carefully, and there was another Taoist rhyme flowing through it, as if an ancient man was saying sadly: From now on, I can no longer see the city of Chang'an, and there is only darkness in front of me.
