In the mountains.

When the black hole appears.

Many soldiers on the scene quickly formed a three-tier defense formation.

The ferrohelium microcrystalline array is also ready to activate at any time.

Soon.

When director Feng arrived, he took the lead in the positive pressure gas analyzer on the left of the several equipment in operation.

A casual technician came to director Feng quickly:

"According to the report, according to the equipment detection, there is no harmful gas overflow near the hole, and the internal oxygen content is almost the same as that outside!"

Director Feng politely thanked him, then thought about it and said:

"Let's start with the mechanical dog and add the chemical sensor."

The mechanical dog mentioned by director Feng does not refer to the single dog of the mechanical department, but the mechanical powered search and rescue dog gradually finalized in the field of small search and rescue.

Yes, of course.

The two kinds of mechanical dogs are actually the same in a sense, that is, they have no wife.

Cough

Soon.

A mechanical dog was debugged and entered the hole under the control of technicians.

This hole is an oval with wide left and right and narrow up and down. The widest part is about three meters and the narrowest part is about 2.4 meters.

The whole hole is obliquely inserted into the bottom of the tombstone. From an angle, it should lead to the lower part of the grave bag, with an included angle of about 30 °.

This shape is more like a cave than a tomb entrance.

The robot dog scuffled into the cave and began transmitting images in real time.

At the beginning, the mechanical dog went very smoothly and sent back a lot of data for research.

However, after traveling about 20 meters, there was a sudden sound of sand on the equipment platform.

A moment later.

A technician raised his head and regretted:

"It is reported that the robot dog has lost contact. The missing position is about 23 meters from the entrance.

From the last byte fed back by the sensor, it should be that the signal is shielded rather than attacked by external forces. "

Hearing these words, director Feng looked at Wei Fan:

"Instructor Wei, what do you think?"

Wei Fan first continued to test the cave with his mind, then raised his eyebrows, said softly:

"Director Feng, there seems to be a shielding array below. It should be that it made the robot dog lose contact.

However, this array has a very long history. If there is no accident

With my cultivation, I should be able to break through it easily. "

Wei Fan's words vaguely showed his attitude, but director Feng noticed another word:

"Old?

Instructor Wei, can you roughly judge when it was left? "

Then he thought of Zhang Daoling in the heavenly palace of Qingcheng Mountain, and continued to add:

"For example, can you tell whether its era was earlier or later than 2000 years ago, when Zhang Daoling was active?"

"It should be longer than two thousand years."

Wei Fan thought carefully and explained:

"What we found at qiangu mountain in Da Mo world was a third-order cloud hidden talisman, so it can only last for hundreds of years.

This may be related to the fact that Mo Peidong thought he should return to qiangu mountain soon, so he only used runes to cover the altar of qiangu mountain.

Compared with the talisman, the life span of the array is much higher.

Generally speaking.

As long as there are enough spirit stones, a small defensive array can last for one or two thousand years, which can be said to be very simple.

The array below the cave is at least no lower than level 3, but now it is broken and can even be broken by practitioners like me who are new to building the foundation.

This shows that it has existed for a very, very long time.

Three thousand years, four thousand years or more. "

Hearing the second half of Wei Fan's words, director Feng immediately contracted his pupils:

"What? Three or four thousand years?

Is it at least the Western Zhou Dynasty? It can even be traced back to Shang and Xia? "

Xia

Business

The Western Zhou Dynasty.

Those who understand history should know that these are three dynasties that can be called the level of ancestors.

According to historical records.

More than 4000 years ago, Yu Chuan was located in Ziqi, which established the Xia Dynasty.

This move changed the concession system of primitive tribes and created a precedent of inheritance in China for nearly four thousand years.

The "family world" in Chinese history began with the establishment of the Xia Dynasty.

As for the later Shang Dynasty and the Western Zhou Dynasty, let alone more introduction, it can be called the beginning of Humanities in China.

The tombs left over from that era also have obvious extraordinary power

It's a little scary.

Therefore, director Feng dared not neglect and hurriedly reported the situation to the core level.

Soon.

While the core layer indicated that it would organize experts to decipher the text, it also sent a new instruction:

Organize a group of seven practitioners to explore in the tomb!

Fifteen minutes later.

A temporary team led by Wei Fan and assisted by Chen Haiyang, deputy leader of the local practice brigade of the Jumang base, was officially established.

The members of the team are the absolute elites of today's mainland. At the lowest level, they have four levels of Qi practice, that is, they can display their mind.

In fact, the precision of shennian is not necessarily comparable to that of a precision instrument. There is no way to give you an accurate result, for example, four or five digits after the decimal point.

But in this environment with extraordinary power, the use of divine mind will be greatly enlarged.

Therefore, the people were not equipped with too many rope equipment, but went directly into the cemetery with gas masks and psionic shields.

The entrance of the cemetery was very large, so people smoothly entered the cave and began to explore.

As a result, Chen Haiyang gradually frowned as he walked:

This tunnel is really "simple".

Not to mention the exquisite stone carvings inside, there is no trace of repair.

Raise your head or reach out, you can directly see or touch the bare and wet rock wall.

This is obviously different from the ancient tomb customs, especially the ancient relic customs in Chengdu.

As a senior local army cadre, Chen Haiyang had been exposed to many things related to archaeology before entering the practice.

For example, Sanxingdui, which is very close to Chengdu.

Not just before the archaeological excavation, Chen Haiyang led a team to take charge of security work.

At the beginning, he had seen the interior of a tunnel with his own eyes. Not to mention how luxurious and luxurious, at least he could see that it was a finely decorated funeral tunnel.

Various stone carvings are arranged, and several lamps can be seen occasionally.

That is, the atmosphere in the saying is full.

Even so for mortals, let alone the extraordinary.

With this strange sense of disobedience, Chen Haiyang's expression and mentality are always dignified and cautious.

Dada dada——

The tunnel was not long, and they soon came near the location where the mechanical dog was missing.

It can be clearly seen at this time.

About four or five meters away from the crowd, there was a emerald green array flashing constantly.

Seeing this, Wei fan turns his head and looks at Chen Haiyang.

Chen Haiyang waved to the team members with a tacit understanding and formed a standby quick reaction formation.

Then Wei Fan took a deep breath and made a decision.

This is a very common barrier breaking method in Da Mo world. You can break through the array nodes.

Under the impact of Taoism.

Less than a moment.

The array was completely smashed.
