Qianyue was still refining the Dragon Phoenix Sacred Heart in retreat, so Ji Tianxing did not disturb it.

He left the sword world with the black dragon and returned to the East China Sea.

When the black dragon appeared in the sky, the huge body of a thousand feet long brought a huge gust of wind, and covered a large shadow of the sea.

It let out a happy dragon chant, circled in the sky, and flew in front of Ji Tianxing and Yun Yao.

Seeing such a big change, Yun Yao also showed an expression of incredulousness, and felt happy and relieved for it.

After a few conversations between the two parties, the black dragon drove Ji Tianxing and Yun Yao towards the Donghai Guixu.

Now the black dragon has reached the first stage of the Soul Refining Realm, and the flying speed is incredible, and it can travel 120,000 miles a day.

Although, this is not as fast as the flying speed of Ji Tianxing's sword.

But its mana is extremely abundant, and its power is long, even if it flies continuously for a month.

...

Five days later, the black dragon carried Ji Tianxing and Yun Yao, flying in the northeast sea area.

Below is the endless blue sea, and scattered islands appear every tens of thousands of miles.

Yun Yao sat on the back of the black dragon, meditating and adjusting her breath.

Standing on the back of the dragon, Ji Tianxing looked at the sea in front of him, his face becoming more and more serious.

He frowned, thinking about something.

Suddenly, Heilong turned his head to look at him, and said in a dull tone: "Old Ji, I feel something is wrong with this sea area."

Ji Tianxing was interrupted in his thoughts, glanced at it with a slightly surprised expression, and asked: "You see the problem too?"

"Yeah." The black dragon gradually slowed down and said in a low tone: "I feel that the seawater in this sea area seems to be darker in color and toxic.

I also noticed just now that there are many fish, shrimp and water monster bodies floating on the surface. "

Ji Tianxing nodded, and said solemnly: "Yes, the seawater in this sea area does contain strong toxicity. Those fish, shrimps and water monsters are poisoned to death.

If I'm not mistaken, something may have happened in this sea area, and there must be more bodies buried under the sea! "

Heilong was silent for a moment, and asked in a worried tone: "Old Ji, Shui Clan will not be in trouble anymore? Shall we take a look?

After all, you and Taiyi are brothers, and I am also a member of the Black Dragon clan..."

Ji Tianxing just thought about it, then nodded in response to the matter.

"Okay, let's go to the bottom of the sea to see what is going on. I have a bad hunch, and I hope it will never happen."

Yun Yao was awakened by their conversation, opened her eyes to look at Ji Tianxing, and asked, "Tianxing, what are your bad feelings?

Do you mean that the changes in this sea area are related to the Demon Race and the Blood God Child? "

Ji Tianxing nodded slightly, and said in a low tone: "Now the Mozu sends a large number of blood gods to slaughter the people of the three clans, and the Shuizu is no exception.

If there are blood gods who enter the East China Sea and massacre the people in the aquatic territory, it will be troublesome. "

Yun Yao understood his worries and nodded quickly: "If this is the case, we shouldn't rush to the East China Sea to return to the market. Let's go to the bottom of the sea to see the situation.

As her voice fell, the black dragon descended from the sky and ‘sigh’ dived into the vast East China Sea.

It is the dragon in the sea, it is effortless to walk through the vast sea, but like a fish in water.

Moreover, it and Ji Tianxing and Yun Yao have the strength of the Soul Refining Realm, and they are not afraid of the severe poison in the sea.

After just a few breaths, the black dragon dived to a depth of ten miles.

The light in the deep sea is dim, the sea is cold, and the pressure is extremely high.

There was dead silence in all directions, no sound was heard, and no fish was seen.

Under the order of Ji Tianxing, the black dragon continued to dive to the bottom of the sea.

When it dived to a depth of thirty miles, it finally touched the bottom of the reef and coral bushes.

The icy seafloor is rich in minerals. There are many rocks and reefs that contain metal components, as well as the luminous water plants, which will shine with a faint light.

However, Ji Tianxing and Yun Yao looked around, only to find that the coral bushes and aquatic plants on the seabed had all withered and died.

In the reef and silt, there are still large tracts of fish carcasses, most of which have rotted flesh and blood, leaving only the bones.

The seawater contains strong toxicity, and there are visible black blood and carrion, which swims slowly with the current.

The black dragon swiftly shuttled across the gloomy seabed, constantly flying to the northeast.

In the process, everyone only saw densely covered white bones on the bottom of the sea, all of which were the corpses of various fishes and aquariums.

Giant whales as large as a kilometer in length, fish, shrimps and shells as small as palms, all were poisoned to death.

Even those water monsters and aquatic people with certain strength can't escape the poisonous erosion. After their deaths, they turn into bones and lie on the dark and cold seabed.

An hour later, the black dragon shuttled thousands of miles on the seabed.

An underwater city appeared in front of everyone.

This is an ancient city with a radius of tens of miles. It is located in a flat reef and is built by countless huge black reefs.

The walls and buildings in the ancient city were all wrapped in algae and various water plants, which looked rather strange and rare.

If on weekdays, hundreds of thousands of aquatic people live in the city, they will graze hundreds of millions of fish and shrimps and feed countless powerful water monsters.

The densely packed schools of fish, various luminous fishes and water monsters will also bring a faint light to the ancient city.

Colorful corals will grow in the ancient city, bringing brilliant colors to the dark ancient city.

Such an ancient city under the sea is gorgeous and spectacular, amazing and delightful.

However, when Ji Tianxing and Yun Yao rushed to the top of the ancient city, they couldn't see the magnificent scene.

What they saw was a cold and dark ancient city, without a trace of light or colorful colors.

There are only hundreds of millions of fish and shrimp carcasses~lightnovelpub.net~ The bones of hundreds of thousands of aquatic people and water monsters are piled up everywhere in the city, exuding a permeating chill of death.

Seeing such a tragic scene, Yun Yao and Heilong felt very heavy.

Ji Tianxing flew into the ancient city, opened Su Xin's eyes, released the power of the soul, and carefully explored the situation in the city.

After a while, he probably found out the reason, and said to Yun Yao: "Yaoyao, I didn't guess wrong, this ancient city under the sea and this sea area were destroyed by poison."

Yun Yao asked solemnly, "Tianxing, can you be sure that this matter has something to do with the Demon Race and the Blood God Child?"

Ji Tianxing nodded, and said in a cold tone: "I had been in contact with the poisonous plague in various coastal cities before, and I personally killed the Blood God Child.

I am no stranger to the power of calamity, and I can be sure that this is the chaos between the blood **** child and the demons.

The sea water contains not only strong toxicity, but also a weak magic energy, which should be the calamity force released by the blood **** child. "
