The age of the Xuanyuan Mausoleum is too old, and the reason why the mausoleum is so hidden is not entirely due to the scheming of the tomb maker.

After thousands of years of dynastic changes, countless emperors who were obsessed with immortality and immortality, or who were simply superstitious about the feng shui of the mausoleum, also had their mausoleums placed near this complex leyline.

For thousands of years, most of the mausoleums have been excavated.

Near the Meridian Ridge in Yan'an, only the Xuanyuan Mausoleum has never been set foot on.

Yan Huan asked Ye Mu for the Night Dagger, and soon disappeared from the sight of the other three.

Each of them was searching for the Codex.

The three of them had no interest in the other treasures buried in the mausoleum, and they always remembered Yan Huan's advice: if you harbor disrespect or greed, you are likely to bring disaster to yourself.

No one had ever seen the Codex and didn't know what it looked like.

But how to think about it, a classic book of ancient times naturally cannot be a scroll, or even a bamboo slip.

The so-called code of law is likely to be a turtle plate engraved with strange symbols, or even a stone tablet......

However, the three of them searched the entire mausoleum, until Song Xiaomin began to see the bizarre mirage-like scene, and there was still no trace of the Xuanyuan Code.

Soon, Ye Mushen and Ling Shang also saw some indescribable hallucinations.

Ling Shang didn't notice it, but when he saw Ye Mushen tiredly leaning against a pair of copper coffins and rubbing his eyes vigorously, and the roots of his fingers were already slightly purple, he noticed that he had lost the sense of feeling cold and warm.

He took out the water bag again and poured some water on a piece of jade that was dented.

Soon, the water froze.

Obviously, the temperature of this Xuanyuan Mausoleum is actually extremely cold.

And for some reason, maybe it's because the place where the Xuanyuan Mausoleum is located is covered by some special energy, maybe it's because the spiritual power of the Xuanyuan Sage is blessed, or maybe it's because the mausoleum buried deep in the center of the earth is affected by special feng shui...... In short, after ordinary people passed through that layer of black fog, they lost their awareness of warmth and coldness in an instant.

Ling Shang couldn't find Yan Huan, but his nerves were numbed by the cold of the underground, and even panic became dull.

If a person loses the awareness of warmth and cold, and stays for a long time in the cold where water can be frozen into ice in the blink of an eye......

Ling Shang had prepared some medicines that might be useful before he came; But in such an environment, even Hua Tuo's reincarnation cannot be guaranteed, and people can stay for a long time without being frostbitten by the cold.

At this point they are hallucinating, which means that they must get out of this place as soon as possible.

When their limbs are completely frostbitten and their hearts and lungs are damaged, only the gods can save them.

Ling Shang figured this out and hurried to Ye Mushen's side.

The latter was still leaning against the copper coffin, and thin bloodshots had already surfaced under his eyes.

His consciousness was getting more and more blurred, and thinking was no longer easy for him.

Ling Shang fed him a crimson pill to protect his heart for the time being.

But this medicine can't completely get rid of the cold in his body, and it can't buy him too much time.

Then she pulled him up, grabbed his hand and did some hilarious-looking stretches.

Song Xiaomin came to the two, and his lips were also blue.

Ling Shang asked him to take the pill and let him do yoga for a while.

When the two of them regained some blood on their faces, they said in an almost cold and calm tone, "If you look for it any longer, it will be a dead end." Let's go back. ”
