The Five Thunder Rectification Method is very powerful, and Tang Ding is already handy in using the Five Thunder Rectification Method.

However, in view of the huge size of this water monster and its rough skin and thick physique, Tang Ding did not spare his Five Thunder Rectification Law at all.

The full eight strikes and five thunder rectifications completely killed this terrifying water monster.

If this water monster lives on land, Tang Ding's Five Thunder Rectification Method may not have such a good effect, because the water monster on land has a balanced yin and yang body, and has a stronger ability to adapt to the Five Thunder Rectification Method of the Supreme Strength and Yang.

But this water monster lives in deep water, living in this kind of water that does not see light all the year round, almost a pure yin environment, and is naturally extremely sensitive to masculinity.

After killing the water monster, Tang Ding sat on the ground and gasped for breath.

Only when we have experienced a severe hypoxic environment will we cherish the oxygen that can be found everywhere in our own lives.

After breathing in the air for a while, Tang Ding suddenly thought about whether the air that flashed in his head before was poisonous?

The cave is diagonally upward, and the entrance is closed by water all year round, so it stands to reason that the air here should be extremely turbid or depleted of oxygen, just like an ancient tomb that has been sealed for thousands of years, and it must wait until the air in the tomb is completely exchanged with the outside world before it can be entered.

Tang Ding took a deep breath of air again, the air here is no different from the outside world, as if there is a place to connect with the outside world.

Oh, in fact, this is supposed to be a thousand-year-old tomb.

Even if this is not the tomb of a widow, it must be the grave of a very powerful person.

Because when Tang Ding was walking up, he saw the mural on the wall of this cave.

Of course, this mural is very simple, but Tang Ding can see its general meaning, the mural on the wall of this cave, probably talks about the appearance of people's production and labor, logging, making tools, ploughing, in short, the mural here is about the various forms of social production and life at that time.

Although the mural is simple, the craftsmanship is quite interesting.

The mural is carved out on the cave wall full of fluorite, the cave wall must first be flattened into a flat plane, and then use a drill to carve the mural on it, because the rock wall is fluorite inside and out, so the light carving is not much effect, this picture should not be seen clearly or clearly, so, Tang Ding noticed that the mural was deliberately brushed with a layer of mercury, although the mercury is very bright, but it just covers the light of the fluorite, and the mercury and fluorite do not look inconsistent.

The more Tang Ding goes up, the more exquisite the murals here are, the more complex the lines, and the richer the colors.

This mining, this mercury on the wall, Tang Ding basically confirmed his conjecture.

It seems likely that this is the grave of the widow Ching. Even if it is not the tomb of the widow Qing, it must be an important figure in Pakistan.

Although Tang Ding didn't see any burials here, this is not to say that the tomb is simple, not to mention anything else, just to say that this mine is full of fluorite, it is not easy to find.

Tang Ding continued to walk, the artificial mining scene of the cave here is becoming more and more obvious, if the opening of the cave is natural, then this place is completely artificially excavated.

Because on the walls of the cave around this, there are no potholes and unevenness when you first entered the cave, but it is very smooth and regular.

Moving on, the mural is gone, it is a huge cave, the cave is slanted upward, the angle is very gentle, and people can hardly feel the effect of the angle when walking.

As he walked, Tang Ding calculated the height according to the angle of inclination here.

But when Dondin entered a huge hall, he completely forgot to calculate the pace and height.

Because Tang Ding was too surprised by what he saw in front of him.

It is a well-lit hall.

This hall is at least 500 square meters, and around the hall, there are oil lamps, and it is this row of oil lamps that illuminates the hall brightly.

In front of Dondin's eyes was a crystal tower.

This crystal tower is circular in shape, the total height is no more than three meters, but the diameter of the lowest floor is five meters, and it is exquisitely built, surrounded by carved beams and painted columns.

There are nine floors in the crystal tower, and although each floor is not high, it can be clearly distinguished from the pedestal that this is a nine-story tower.

Of course, what surprised Tang Ding the most was not the crystal tower, but the contents of the crystal tower.

The crystal tower is silver, and if Tang Ding is not mistaken, this crystal tower should be mercury.

But there is not only mercury in this crystal tower, but also treasures on every floor from the bottom of the crystal tower.

The treasure was immersed in mercury, which should not have been visible, but the jewel and jade were densely attached to the crystal tower wall, so the treasure was exposed.

But this treasure can't be exposed by itself, and it is not deliberately placed close to the wall of this crystal tower, so there is only one possibility, that is, this crystal tower is full of treasures, so there are so many treasures pasted on the wall of the crystal tower.

This crystal tower, five meters in diameter, three meters high, although the tower is smaller and smaller the higher it goes, but the nine-story tower is full of treasures, and the number of treasures is also an astronomical number.

Oh, wrong, it's not that the nine-story tower is full of treasures, and it's not that the nine-story tower is filled with mercury, but only eight layers are filled with treasures, and eight layers are filled with mercury.

On the ninth floor of the crystal tower, there is no mercury or treasure, but there is a person lying quietly inside.

This is a woman, a woman in white.

As for the appearance of this woman, because of the angle, Tang Ding can't see it.

However, the strange sight of a person lying in a mercury tower full of mercury and jewels and jade everywhere under his body, if a timid person is lying on his body, he will be paralyzed with fright on the spot.

This nine-story tower is a crystal coffin!

If Tang Ding's expectations are not bad, the woman in this crystal coffin should be a widow.

If an ordinary person sees this scene, he will definitely run to the front of the crystal coffin first, and watch the crystal coffin carefully, and the archaeological person may go to see the person first. Tomb robbers will go to see treasures, and even if they look at people, they will see if there are more valuable treasures on people.

But Tang Ding is different, since he has seen the crystal tower, now, he does not look at people or treasures, but looks at the surrounding environment.

In Tang Ding's heart, the surrounding environment is also very strange.

The oil lamps are always bright, and the hall is illuminated as if it were daytime.

The oil lamp here just illustrates the source of the fluorite light source on the cave wall.

Fluorite can't actively emit light, it must be illuminated by a light source to emit light, but in this dark hole, how can there be a light source?

Of course, this was Dondin's question at the beginning, and now his doubt is gone, because he sees the light source.

However, Tang Ding had a new question: there is a light source here because there is an oil lamp, but who lit the oil lamp? Could it be that there is someone here?

If there's no one here, then how can the air be so fresh, and if there's no one, what's going on with the oil from the oil lamp?

If this is really the tomb of the widow Qing, then it is at least 2,000 years ago, and what oil lamps will last for more than 2,000 years?

However, Tang Ding read too much, and he suddenly remembered the record about the ever-bright lamp in a miscellaneous book he had read:

The everlasting lamp made of the fat of the mermaid will not be extinguished for thousands of years.

Tang Ding has never seen a merman, and he doesn't believe that there is an oil lamp that will not be extinguished for thousands of years, but how can he explain the scene in front of him if this is not an everlasting lamp that has not been extinguished for thousands of years?
