Not long after swimming, Jiang Fei showed a surprised expression. He remembered that there was nothing on the cave when he came, but now after being soaked in sea water, inexplicable runes appeared on the walls of the cave.

Those runes emit a faint fluorescence, which looks very mysterious.

"It's really strange. There were obviously no runes just now." Xue Zhi said in surprise.

"Can you understand these runes?" Jiang Fei asked quickly.

Xue Zhi shook her head and said, "I have never seen such a rune before, and I can't understand it at all."

Jiang Fei was very depressed. He had never seen such runes before. Zi Ling could not recognize these runes that appeared inexplicably. Jiang Fei called Zi Tong, but unfortunately he had never received a response.

Jiang Fei gritted his teeth and said, "Let's go over and see what the red light is."

Xue Zhi nodded, and they swam quickly towards the depths of the cave. Just as they were about to approach the red light, the sea water completely submerged them.

Soon they arrived at the place where they were emitting red light, which was the place where they were sleeping. There was nothing just now, but after being soaked in the sea water, a huge gem with red light appeared on the ground.

This gem is very strange. It is oval and looks like a huge egg with red light shining on it, and some weird runes are constantly shining on it.

"What is this? How come such a huge gem suddenly appeared?" Jiang Fei said in confusion.

Xue Zhi shook her head and said, "I don't know it either, but I can feel that there seems to be a very powerful force hidden in this gem."

"Let's go down and take a look." Jiang Fei said and swam towards the gem.

When they approached the gem, the light on the gem suddenly disappeared, and then turned into an inconspicuous black stone, and the runes on the surrounding walls also disappeared.

The two were very shocked. Jiang Fei hurriedly stepped forward and touched the stone. He did not notice anything. This was an ordinary stone like the surrounding stone wall.

The two of them studied it, but unfortunately they didn't find anything. Jiang Fei tried to move it. Unfortunately, the stone was very heavy, and with Jiang Fei's physical strength, it could not move at all.

Xue Zhi said anxiously: "We'd better leave here as soon as possible, otherwise we'll really drown here."

Jiang Fei thought about it and couldn't figure out what this strange stone was. He would definitely be drowned if he stayed here. Although he would encounter the ancient giant crocodile when he went out, there was still a glimmer of life, so he nodded.

Just as the two were about to swim outside, Zi Ling's voice suddenly appeared in Jiang Fei's mind: "I just checked it, and that gem seemed to contain vitality."

Jiang Fei was very excited. It was not because Zi Ling found that there was vitality in the gem.

"You can find out that there is vitality in that gem. So your power is not suppressed?" Jiang Fei said quickly.

"I didn't touch the strange sea water, so naturally I was not suppressed by it." Zi Ling said.

"It's so great, so I'll be more confident." Jiang Fei said excitedly.

As he said that, Jiang Fei quickly swam towards the entrance of the cave. Zi Ling quickly said, "There is vitality in that gem. Don't you plan to go back and take a look?"

"If I stay here, I will be drowned, but I don't have time to investigate. I'll talk about it if I have the chance in the future." Jiang Fei said.

"But I think it can prevent you from going out and taking risks." Zi Ling said.

Jiang Fei stopped immediately, and he hurriedly said, "Are you saying true?"

"You'll know if you go back and take a look." Zi Ling said.

Seeing Jiang Fei stop suddenly, Xue Zhi turned her head and looked at Jiang Fei anxiously. She hurriedly said, "If you don't go out, you will be completely submerged. Why are you stopping?"

"Let's go back and take a look. Maybe the gem will prevent us from going out for adventure." Jiang Fei said.

Xue Zhi stared at Jiang Fei and said, "What did you find?"

"Nothing has been discovered yet, but if I go back, I believe I will be able to discover something soon." Jiang Fei said.

Xue Zhi hesitated for a moment, finally nodded, and then the two of them swam back.

"You check it out quickly. We don't have much time left." Jiang Fei urged Zi Ling to say.

"Don't worry, look at me." Zi Ling made a magic trick.

Suddenly, light flashed on Jiang Fei's body, shining towards the gem.

Xue Zhi looked at Jiang Fei in surprise and said, "You are not suppressed."

"I was indeed suppressed. Now I am using my magic tricks." Jiang Fei explained.

Xue Zhi stared at Jiang Fei with incredible emotion and said, "Your spiritual pet is so powerful that you can use magic if you don't come out."

Hearing Xue Zhi's praise, Zi Ling worked harder and continued to penetrate the gems one by one.

"How is it? What are you finding?" Jiang Fei said.

Zi Ling frowned and said, "There is a powerful seal in this gem, and with my current ability, I can't break it."

"You should think of a solution quickly. We don't have much time left." Jiang Fei said anxiously.

"There is a blood curse above this gem. I need people to use blood to help me restrain the power of the seal, so that I can have a way to break the seal of this gem." Zi Ling said.

Hearing this, Jiang Fei quickly raised his hand and was about to bite his finger. Zi Ling said in surprise: "What are you doing?"

"Don't you need blood? I'll give it to you now." Jiang Fei said.

Zi Ling shook her head and said, "Your body contains the blood of the Demon Emperor, which is not possible at all. This is the seal of the immortal way. Your demon blood will make the seal stronger."

"What should I do?" Jiang Fei was depressed, and he didn't expect that his blood would not be used.

"Try it with that blood of Xue Zhi." Zi Ling said.

Jiang Fei looked at Xue Zhi, then said, "Can you borrow your blood and use it?"

Xue Zhi said with some confusion: "Why are you lending my blood?"

"If the seal is untied, it takes blood. Unfortunately, I can't use mine, so I can only use yours." Jiang Fei said.

Xue Zhi thought for a while, then nodded and said, "What should I do?"

"You just need to put the blood on the gem." Jiang Fei said as Zi Ling told him.

Xue Zhi swam in front of the gem, then bit her finger, and a bright red ray appeared in the water. She quickly pressed her hand on the gem.

At this time, Zi Ling quickly made several magic tricks, and the blood that had melted into the water condensed, and then quickly merged into the gem.
