The black ancient coffin, buried dozens of meters underground, is the only entrance, which is extremely narrow, and only creatures the size of rats can barely pass through.

Zhang Xiaofan was too big to get into.

Unless he dug up the ground and opened a shaft, he would not be able to get close to the black coffin.

The small egg is petite and can burrow into it unimpeded.

However, Zhang Xiaofan didn't dare to let it chase and kill the monster alone.

Although Xiao Dan is a descendant of the Golden-winged Dapeng Bird, he is too young and weak at present, except that his resistance to blows is more perverted, and he is no different from a weak chicken.

Therefore, Zhang Xiaofan will not let Xiaodan take risks.

This mysterious monster, he has to deal with it himself.

Without further ado, just do what you say.

Zhang Xiaofan opened the treasure bag of his mobile phone and took out a military shovel from it.

The treasure bag has hundreds of storage compartments that can store many things, in addition to those red envelopes from the immortals, Zhang Xiaofan also stores some tools in it in case of emergency.

This military shovel, which was previously purchased online, was sent to use today.

Boom! Boom! Boom!

Zhang Xiaofan raised his leg and stomped a few feet on the ground.

As if trampled by a giant beast, the hard concrete floor instantly cracked and collapsed. Zhang Xiaofan pried open the broken stones, revealing the soft soil underneath, and then began to dig a pit.

Whew!

Zhang Xiaofan wielded a shovel and dug quickly, with an efficiency comparable to that of dozens of workers working at the same time.

In the blink of an eye.

On the ground of the underground garage, a small mound was piled up.

Zhang Xiaofan dug a shaft, and it was less than five meters away from the black ancient coffin.

This ancient coffin seems to be a piece of 10,000-year-old ice, and the closer it gets, the stronger the chill on Zhang Xiaofan's body becomes.

"Brother Fan, dig quickly, dig quickly!"

Xiao Dan stood on Zhang Xiaofan's shoulder, constantly chattering, looking extremely excited.

Dig a few more meters.

Zhang Xiaofan was only separated by a thin layer of soil from the black ancient coffin.

"Whew!"

Zhang Xiaofan exhaled a breath of white air and rubbed his somewhat stiff hands. At this moment, the chill he felt was already a bit biting.

The black ancient coffin below was still lifeless, and there was nothing abnormal.

Even the mysterious monster hiding in the ancient coffin didn't make any movement.

Zhang Xiaofan didn't dare to be careless, holding a shovel in one hand and secretly pinching the sword qi in the other, for the sake of safety, he also took out a life-saving sweat hair, and once the situation was not good, he immediately summoned Sun Dasheng's clone.

After making sure that everything was safe, Zhang Xiaofan used the shovel in his hand and gently flicked it downward.

The fine soft loess was turned open, revealing a black stone slab.

This ancient sarcophagus buried deep in the ground is very huge, and the shaft dug by Zhang Xiaofan only exposes a corner of it.

The sarcophagus is made of a mysterious black stone, like a black crystal, blooming with a deep and bright black glow. It was this black glow that blocked his heavenly eye, making it impossible for him to peek into the inside of the sarcophagus.

"Brother Fan, what is this?"

The little egg suddenly jumped down and jumped onto the sarcophagus.

"Be careful!"

Zhang Xiaofan's heart tightened, and he exclaimed.

"Brother Fan, rest assured."

The little egg was bouncing around on the sarcophagus, and the sarcophagus below was unresponsive.

Seeing this, Zhang Xiaofan hesitated a little and jumped onto the sarcophagus.

A biting chill spread through the soles of his feet and throughout his body, making him shiver involuntarily.

Other than that, everything works fine.

"Huh?"

Zhang Xiaofan was surprised, the black light emitted by the ancient coffin seemed to be no other danger except for being extremely cold.

"What is the origin of this sarcophagus?"

Zhang Xiaofan became more and more puzzled in his heart.

Who buried this mysterious ancient coffin here, and what is hidden inside? Also, what does that evil monster have to do with the sarcophagus?

After a half-silence, Zhang Xiaofan waved a shovel and continued to clean the soil on the surface of the ancient coffin.

Soon.

The ancient coffin was cleaned out in a large piece, and the whole ancient coffin was rectangular, with a smooth surface like a mirror, but there was a small circular hole in the center.

It was through this small hole that the mysterious monster escaped into the ancient coffin.

Besides.

Zhang Xiaofan also noticed that on the surface of the black ancient coffin, there were some strange-shaped oracle bone inscriptions.

Zhang Xiaofan naturally doesn't know anything about these oracle bone inscriptions, although he is well-read, but he has no research on ancient oracle bone inscriptions.

However, just because he doesn't understand oracle doesn't mean that others don't know oracle either.

Zhang Xiaofan turned on his mobile phone, searched for Oracle-related content, and soon found an academic website called 'Oracle Home', which contained a lot of information about Oracle.

Some professionals study and translate the oracle bone inscriptions from archaeological finds, and upload the results to the website.

Zhang Xiaofan swept his eyes, memorized the oracle bone inscription on the sarcophagus in his mind, and then entered the website to search.

The oracle bone inscriptions on the sarcophagus, a total of seventy-nine.

Relying on the database on the website, Zhang Xiaofan recognized nearly two-thirds of the oracle bone inscriptions.

After translation and brain supplementation, Zhang Xiaofan made a discovery.

In just a few dozen oracle bone inscriptions, the identity of the owner of the ancient coffin is briefly introduced.

It turned out that the person buried in the ancient coffin was a woman named Fu Xi, and this ancient coffin was called 'Yin Sarcophagus', which can gather the yin qi of the world and will not disperse for thousands of years.

Not only that, the burial place of this ancient coffin is known as the place where the nine yin are crossed.

"Nine Yin Jiaotai, the Yin sarcophagus that gathers Yin Qi, the mysterious ancient woman ......"

Zhang Xiaofan stared at the sarcophagus under his feet, and felt more and more that this black ancient coffin must be hiding some secrets.

"Brother Fan, there's something in it!"

At this moment, Xiao Dan suddenly exclaimed.

"What's that?"

Zhang Xiaofan swept his eyes and saw that Xiao Dan was lying outside the small hole, and he looked hard into the ancient coffin.

"I can't see clearly."

Xiao Dan raised his head, looked at Zhang Xiaofan, and said, "The fog inside is too thick." ”

"Fog!"

Zhang Xiaofan's eyes narrowed slightly, this Yin sarcophagus has been buried here for I don't know how many years, and countless Yin Qi has gathered. When the yin energy is thick to a certain extent, it will turn into a yin mist.

From the fog to the cold and the ordinary people touch it, they will die.

Of course, Zhang Xiaofan is no longer a normal person, and he is not too afraid of the terrible mist.

"Brother Fan, I'll go in and take a look first."

The little egg waved his little wings, looking eager to try.

"Don't die!"

Zhang Xiaofan glared at the little egg, who had always been bold, and said, "Your wings are not hard yet, be honest with me!" ”

"Yes!"

The little egg died down in an instant, and the deaf head responded.

"What's the hurry, if you want to enter, let's go together."

After Zhang Xiaofan exhaled lightly, he waved the shovel in his hand and continued to work.

An hour later.

Zhang Xiaofan dug out a huge cave and cleaned up all the soil around the Yin sarcophagus.

"Brother Fan, open quickly!"

Little Egg was excited again.

"Hehe, the mystery is about to be revealed."

Zhang Xiaofan grinned, stretched out his hands, and pushed open the heavy coffin lid.
