Since the United States was equipped with nuclear weapons, there have been hundreds of "broken sword" accidents, of which nearly 100 nuclear warheads have been lost, and more than 10 of these nuclear bombs have been found so far, and most of them have sunk into the deep sea that cannot be explored by mankind.

Chen Yan didn't dare to touch this nuclear bomb, and the nuclear radiation leaked.

Chen Yan stayed away from this sea area.

A little guy floated past Chen Yan.

There are blue circles on it.

This little guy is called the blue-ringed octopus, it is highly poisonous, don't touch it, bite it and die.

In fact, there are beautiful scenery on the bottom of the sea, and the coral reef is a colorful world, with colorful small fish roaming in the corals, white and soft sand, and the sun shines on the bottom of the sea, forming a circle of light spots on the bottom of the sea,......。

Chen Yan found a big blue hole, and he was going to explore it.

Chen Yan swam to the top of the big blue hole.

The color of the Great Blue Hole is dark blue, which distinguishes it from the light blue of the surrounding sea.

Chen Yan's body dived down, and he also brought a depth counter.

10 meters. It's already down to a depth of 10 meters.

100 meters. It's already down to a depth of 100 meters.

1000 meters.

2000 meters.

……

5000 meters. It has been dived to a depth of 5000 meters.

10000 meters.

12000 meters. It has dived to a depth of 12,000 meters.

20,000 meters. There's no bottom yet.

The deepest part of the ocean is not the Mariana Trench.

The depth of the Great Blue Hole has far exceeded the 11,034 meters of the Mariana Trench.

Chen Yan slowly dived back to the surface.

What Chen Yan encountered in the ocean, if he wrote a book that revealed the secrets, it would definitely sell very well.

An Indian Scorpene-class submarine fell into depth, disintegrating at a depth of several thousand meters. And the Indian military withheld this information from the public.

At the bottom of the sea there is a lost Mark 4 nuclear bomb of the US military.

The deepest part of the ocean floor is not the Mariana Trench, but this large blue hole, which is bottomless for 20,000 meters.

Look for the city of Chretia submerged under the sea.

A few days passed.

A week passed.

……

A month has passed.

Still not found.

Chen Yan walks on the bottom of the sea.

Suddenly stopped.

Chen Yan found a red coral, this red coral is like antlers, 1 meter high, with more than a dozen forks, bright red, as red as chicken blood, this is a gem-level red coral, extremely precious, if this red coral is placed in ancient times, it will definitely be a tribute treasure level, and it will be paid tribute to the emperor and treasured by the royal family.

Chen Yan picked the red coral and put it into the spiritual water bead space.

……

Staying in the sea for a long time made Chen Yan psychologically claustrophobic and depressed.

Chen Yan returned to the island of Micronesia to rest for two days.

After resting for two days, Chen Yan continued to search for the city of Chretia that had been submerged under the sea.

Chen Yan swam in the sea like a fish, more than 100 meters above the surface of the sea.

Chen Yan suddenly felt a fluctuation in the surrounding seawater.

Chen Yan dived one by one and dived to the bottom of the sea.

It turned out to be a sperm whale vs. king squid, and it should be a sperm whale that abused the king squid.

Legend has it that the king squid is very bullish and is often said to be a giant beast on par with sperm whales by stall texts or some unscrupulous popular science texts. Now it seems that the king squid really has no combat power against the sperm whale, the king squid was eaten by the sperm whale in a few minutes, and the legendary king squid's nirvana used tentacles to wrap the sperm whale's head around and block the nostrils before it came out.

The sperm whale left.

Chrettia City ...... Finally found it.

In the place where the sperm whale fought the king squid just now, the flashlight shone through, Chen Yan found the road paved with stone slabs, and then, Chen Yan used a flashlight to shine around, the broken wall, a half-section of the stone tablet was erected, in front of him, it can be seen that it is the outline of a straight road, and the road paved with stone slabs was buried in the sand because of the water flow.

Chen Yan swam like a fish above the ruins of the city.

It took 2 hours to look down and visually see the ruins of the whole city.

The urban layout of the city of Chrétia is unconventional, one vertical and one horizontal two wide roads paved with stone slabs, a river passes through the city of Chrétia, the east of the city is the port, the wharf, shops, and the craftsman area, the west and south of the city are residential areas, the low inhabitants live in adobe bricks, the north side of the city is the area where the nobles, officials, and big merchants live, the houses they live in are tall and sturdy, made of green bricks, strips of stone, and the center of the city is the royal palace, the temple, and the planetarium, theater and other public buildings are located.

Chen Yan began to search for the treasures of Chretia City.

Start the search first with civilian settlements.

It took a week to search the civilian settlements, and a large number of coins were obtained, very few gold coins, mostly silver coins, copper coins, probably hundreds of thousands of silver coins, millions of copper coins, and a large number of pottery and bronze utensils, most of which were household utensils of the inhabitants.

Chen Yan also found a lot of stone tools such as stone mills, stone mortars, and stone pans.

The Cretian civilization mastered the technology of iron smelting, and the iron weapons cast were very sharp, and the iron tools were rusted away because they were soaked in the sea for a long time, and the organic matter such as clothes, hemp rope, paper, and wooden furniture were also soaked in the sea.

Chen Yan collected these harvests into the Spirit Water Bead Space.

Next, search for the City SB district. The northern part of the city was inhabited by nobles, officials, and large merchants, and the harvest was a little more.

Chen Yan entered a house made of blue bricks.

The brick house is so sturdy that it hasn't collapsed into ruins.

At the gate there are two watchmen carved out of stone.

Chen Yan collected the two gatekeeper beasts into the Spirit Water Bead space.

Enter the house.

Chen Yan found several boxes of gold coins in a room, as well as a large number of silver and copper coins.

Chen Yan found a lot of decorative carvings on the eaves and beams, which were very delicate and lifelike.

Chen Yan collected these into the Spirit Water Bead Space.

For tens of thousands of years, if not hundreds of thousands of years, the city of Chrétia was submerged under the sea, and there was no hope of anything but gold, silver, copper, and precious stones, stone carvings, and pottery, either rusted or soaked.

Half an hour, a house was searched.

Chen Yan entered another house.

The owner of this house must have been a wealthy merchant or a nobleman.

The house was built too lavishly.

The house covers an area of more than 40 acres, and there are two watchmen beasts standing at the door, and the watchmen beasts are carved lifelike, majestic, and twice as big as the two watchmen beasts just now.

Walking in through the door, the inside suddenly opened up.

Chen Yan found more than a dozen boxes of gold coins, several boxes of gems, and a large number of silver coins and copper coins in a room, because the wooden box containing the gold coins was soaked in the sea, so the gold coins were piled up into more than a dozen piles, Chen Yan roughly estimated that there were thousands of gold coins in one pile, and tens of thousands of gold coins in a dozen piles.

……

It took Chen Yan a week to 'ransack' all the houses in the SB district of the city.

Gold coins are piled up in the space of spiritual water beads.

Silver and copper coins are piled up in dozens of piles.
