Liu Longba here made him feel something was wrong, especially when he first came in, Liu Longba's eyes seemed to be full of murderous intent, and he wanted to kill Lin Feng on the spot. However, there were so many people here, especially

Lin Feng became Xian Sishi's man again. If he really did this, Liu Longba would no longer have to hang out in the Tenglong Empire.

No matter how powerful Liu Longba is, he is still over 30 years old. Only those under 30 years old can participate in this imperial war. If you kill the future of the Tenglong Empire, it will not be a pity to implicate the nine tribes.

Lin Feng glanced at it and saw that there were only twelve people here. Each of the five princes brought one, which made ten people. Plus Xian Sishi and himself, there were twelve people in total. I wonder if Luo Yunlong would choose

Go in. Even if you go in, there are only thirteen people. This number is really too small.

Originally, Luo Xuan didn't plan to enter, but neither of the two places were given out, so he wanted one for himself and added a confidant.

"Isn't the number of people a little too small..." Lin Feng tilted his head and said to Xian Sishi.

"That's quite a lot. Only fifteen people can stay inside at most. Anyone who exceeds this number will not be allowed in. We have just the right number of people, no more and no less." Xian Sishi said.

Lin Feng raised his eyebrows. According to this, it means that there are three people inside who have been staying inside for a long time. Who are these three people? No need to guess. They must be those who are immortal and at the level of elders who protect the country. They will not be in danger until the moment of crisis.

They won't come out. Their lifespan is about to end. If they don't break through, this life will really be over.

These strong men become more afraid of death as they get to the back, and they really won't come out until a critical moment.

Lin Feng didn't say anything, he just shut up and stood aside, waiting for them to activate the teleportation array.

Then Luo Yunlong took out a stone slab from the storage ring, went to the groove next to the teleportation array and stuffed it in. Suddenly the spiritual crystals arranged around the teleportation array lit up, and he quickly poured spiritual power into the teleportation array, and then

The entire teleportation array was lit up, and a wave of energy rose up.

"Get ready, we are about to start teleporting to the royal secret realm." Luo Yunlong reminded.

Everyone relaxed their whole bodies. After a while, the teleportation array was lit up, enveloping everyone in it. In the blink of an eye, everyone disappeared, as if they had never appeared here.

"I hope you can gain a lot next time you come out..." Luo Yunlong nodded, took out the stone slab and left the palace.

If you want to use this teleportation array, you must pass Luo Yunlong's stone slab to enter. If you come out, you won't need this stone slab. Therefore, the secret realm of the royal family is in Luo Yunlong's hands. Whoever wants to enter can enter.

, it all depends on his mood.

In the blink of an eye, Lin Feng felt that he had arrived in a space with very strong spiritual power. The concentration of spiritual power here was the richest he had ever seen! Looking around, he found that he was not in a palace, but in a place.

In an extremely wide cave!

"The spiritual power here is too strong. Is this the secret realm of the royal family?" Lin Feng looked around and saw a few spiritual crystals that had not been collected, but there was only a little left.

In addition, there is not even a blade of grass, that is, there are no plants, and it looks very desolate. But the concentration of spiritual power here is very strong, at least ten times stronger than the outside world! It is much denser than that in the training room.

Times, quite astonishing.

"Yes, this is the secret realm of the royal family. To be precise, it is the underground of the palace, which is where the spiritual veins are. Therefore, the spiritual power here is quite strong. The spiritual power in the training room outside is led out from here.

That's right up here." Xian Sishi pointed to the top of her head, indicating that the training room was up there.

Lin Feng suddenly realized that this was what happened. He simply sent them underground and did not spread them too far.

The others had long been used to it and quickly walked in, ignoring them. As for saying hello to Xian Sishi, they didn't pay much attention at all. They felt that Xian Sishi was not their sister, but a stranger.

Xian Si's eyes were expressionless, and he had long been accustomed to this. He continued: "Let's go forward. The more spiritual power inside, the stronger it is. It is a good place for cultivation, but our purpose is not here, but in this secret realm."

center."

"How long can we come in here?" Lin Feng asked.

"Almost half a year, I will train directly until the next imperial exchange battle." Xian Sishi replied simply and rudely.

Lin Feng took a breath. This training time is really long. No wonder so many people want to come in. Just being able to practice here for such a long time can make him improve by leaps and bounds!

As they went deeper, the concentration of spiritual power became higher and higher. He really wanted to put a compression device here to feel how many spiritual crystals could be produced here. But this was impossible, there were so many people here,

If you actually take it out, it won't be taken away.

After passing through the long and narrow passage, when they took the last step, their eyes suddenly opened up. What came into view was a huge palace. What was shocking was not how luxurious this palace was, but that this palace was made of spiritual crystals!

All are made of colorless spiritual crystals, and are slightly transparent. They look like a crystal palace, which is very beautiful. The rich spiritual power emanates from this palace. Lin Feng feels that he has been practicing here for a day

, it can be absorbed by the outside for a few weeks. The concentration is really amazing.

"I didn't expect that there would be a palace built with spiritual crystals underground. This is too rich..." Lin Feng smacked his lips. If he was given a separate training room and allowed to absorb it like crazy, it would be really fast.

I can reach full spiritual power and break through to the fourth level.

Thinking about it, he felt extremely excited. What could be more important than upgrading the energy conversion device? That kind of improvement is definitely a qualitative leap.

"This is the underground palace. Our elders who protect the country are practicing here. Don't disturb them. Otherwise, if they make them angry, it will be difficult to solve." Xian Sishi looked solemn and looked at these old guys.

They all feel extremely headaches and refuse to come out until the most critical moment. This is a waste of resources.

It's okay to achieve a breakthrough in cultivation, but when you practice until you die, you haven't even taken a step out, and so many resources have been wasted.

"Did you build this place?" Lin Feng asked doubtfully.

"No, it was built on this basis when we discovered this place a long time ago. I don't know which power left it here, and there is no indication at all." Xian Sishi said truthfully.

With that said, they walked into the Crystal Palace together. The inside looked similar to the outside. It was basically empty and there were no furnishings. When they came to the center of the palace, Lin Feng discovered that there were five teleportation arrays, which were completely different.

Know where to send it.

"These five teleportation arrays are all secret realms of cultivation that are transmitted in different directions. They have five attributes: metal, wood, water, fire, and earth. You can choose according to your own physique." Xian Sishi asked: "I wonder what kind of attributes Mr. Lin chooses?

"

Lin Feng thought about it for a while. He didn't care at all. He didn't really care what attribute it was. In the end, he casually said: "It's fire attribute."

"Judging from Mr. Lin's physique, the fire attribute is indeed a better choice. The space attribute is not available here." Xian Sishi said.

It's a good thing that he didn't choose other attributes, otherwise it would be really strange. He already knew that he was being investigated clearly and would never miss any information.

At this time, everyone else had already chosen their attributes, and only the two of them were left. Lin Feng looked at the teleportation array where Liu Longba disappeared, and felt it was quite strange. It seemed that Liu Longba really didn't dare to take action.

"Then I will go to the water attribute first. See you again after a while. Be careful in the secret realm. It is not safe here. I believe you can find a solution yourself." Xian Sishi walked straight to the water attribute teleportation array.

, disappeared in the blink of an eye, and just reminded her casually that if she wanted help with everything, then there was really no need for her to ask Lin Feng for help.

Lin Feng glanced at it and finally chose the wood attribute teleportation array. He walked towards the teleportation array and disappeared in the blink of an eye.

The moment he disappeared, a teleportation array suddenly lit up. Liu Longba came out of the teleportation array, glanced at it with a frown, and said in a deep voice: "It's strange, why did he choose the wood attribute?"
