More than ten days have passed, and Long Fei has spent a week constantly combining the formations he has learned and arranging them all here.

The rest of the time is continuous refinement, while waiting for the completion of the underground works.

The ground here has been compressed by Shanhui, so the ground has become extremely tight and hard, so it took them so much time.

"Hahahahaha...... It's finally done! I'm tired of my old bones!"

Tired but not too weak, old but in good spirits, Long Fei immediately guessed where the voice belonged.

Looking up, at the end of the formation, in a prosaic place, a stone lay there, and next to it there was a flat field.

The sound came from that direction, and I saw the flat ground move slightly, and finally revealed a hole, and a figure slowly walked up from there.

This figure is none other than Reiwa, who went to complete the task, and it took more than ten days for them to finally succeed.

And behind Reiwa was Wang Jie, who also had a smile on his face and the relaxation to complete the task.

"My lord, the two of us have worked together to open up the cave below, just waiting for your inspection. ”

Ling He bowed to Long Fei and said loudly with joy.

"Yes, my lord, you can go and take a look, if you are not satisfied, we can change it again"

Wang Jie also said respectfully, but his words were full of confidence, which was confidence in his work.

"Seeing that you are so confident, I think there will be no problem, so let's enjoy it!"

Long Fei was also a little curious, not knowing how far they had gone and how confident they were.

"Your Excellency, please!"

Reiwa stretched out his hand to make a gesture of please, and then the two of them took Long Fei and walked towards the entrance.

Long Fei walked in front, and the two followed behind, and walked into the cave together.

The hole went down, and it was made up of a row of stairs, and it took about three minutes to walk before they reached the bottom.

"My lord, there are two hundred and sixty-six meters from here to the entrance of the cave, and all of them are reinforced with a layer of black iron, which is extremely stable."

Reiwa hurriedly introduced.

"Well, yes, I felt it just now, and I couldn't spread my perception in it, so I guess it was the addition of Kong Shi!" Long Fei asked.

"Adults have good eyesight, so that if outsiders reach out to their perceptions, they will be deceived and will not know that there is something else down here"

Wang Jie said proudly, thinking that this idea came from him.

From here, there is a corridor, and a faint light can be seen from a hundred meters away.

But Long Fei didn't continue to move forward, but looked up at the sides above his head, and he vaguely felt that there was something there.

"Brush ......"

Two figures suddenly jumped down from there, kneeling in front of Long Fei, one left and one right.

"Tianqing, Tianming, see your lordship, welcome your lordship. ”

The two said respectfully together, waiting for Long Fei to speak.

"Hey, why are you in such a hurry to come down? I haven't sold it yet!"

Reiwa said dissatisfied, but there was smugness on his face.

"Commander of the Qi Order, your lord has sensed us"

The two spoke respectfully together.

"He Lao, I haven't sensed it safely, you better hurry up and introduce me!"

Long Fei said with a smile, this and the old man will be so naughty.

"Yes, my lord, I have made two small places out of holes, which can hold one person, so that the effect of concealment can be achieved."

Reiwa said, the smug look was unmistakable.

"Yes, so that people can be inside, always on the lookout for people outside, and in this area, we have set up a lot of mechanisms, if someone breaks in, people hiding in two small spaces can attack"

Wang Jie added.

"Okay, good idea, really good" Long Fei was very satisfied, this was too thoughtful.

"The people inside can also pass on messages, and the mechanism here is also very powerful, every weapon is coated with poison, it can be said that you will die."

Reiwa looked at Long Fei and added proudly.

"Let's go ahead and take a look inside. ”

Wang Jie said and walked forward.

Long Fei nodded to the two kneeling there, and then followed.

Walking to the end of the corridor, a wide hall was revealed, and the three of them walked in together.

The ground here is extremely smooth and bright, reflecting the light above your head, breaking through all the darkness.

Long Fei looked up, and there were rows of glowing stones, illuminating the place.

The hall is large enough to accommodate more than 1,000 people without the slightest crowding.

Around the hall, there are four staircases that lead in four directions.

"My lord, this is the place where we discuss things, and the ends of those four stairs are all rooms for everyone to practice and live. ”

Ling He said to Long Fei that he did not completely follow the copywriting given to him by Long Fei, but added his own ideas.

"And, there are a total of 5 exits here, the place where we just entered is the main exit, and at the end of those rooms, there is also an exit, but they are all relatively hidden, and outsiders can't find them at all!"

Wang Jie introduced, with a mysterious smile on his face.

"Oh, what a hidden method?" asked Long Fei with a smile.

"Let's take one, let's talk about the entrance of the cave! We have placed the exit in a big mountain thousands of kilometers away from the Ten Thousand Beast Sect."

Wang Jie said confidently that this was what they thought of after thinking about it carefully.

"The so-called three holes of the cunning rabbit, we have set up so many exits, also for the sake of safety!" Reiwa hurriedly continued.

"Okay, see what you say is perfect, so be it! I'm very happy here."

Long Fei nodded and said, a smile on his face.

"By the way, what's wrong with that high-grade spirit vein?"

Long Fei asked, if there is really a top-grade spirit vein, coupled with the supply of pill spirit stones, the cultivation speed of this team will definitely be even faster.

"That high-grade spiritual vein, we have discovered it, through the bondage of the formation, we have used it, and every room can absorb it"

Ling He said with a smile that when Long Fei told him that there was a high-grade spiritual vein here, he still didn't believe it.

After all, this is the Ten Thousand Beasts Sect, a four-grade sect, how can there be such a spiritual vein.

When they found it, this high-grade spiritual vein was still evolving, and he could be regarded as witnessing the formation of a spiritual vein, and his face was suddenly full of surprise.

"Now that it's done, let's let our people come down"

Long Fei said that it is necessary to seize all the time and strive to improve the combat effectiveness and cultivation of this team.

He vaguely felt that the demon clan would not go on like this, and they would definitely have new plans, so they had to be ready at any time.

The next step was simple, everyone in the team moved here, and after they found their own accommodation, everyone began to cultivate.

"Fei'er, now that your cultivation has reached the late stage of the Yuan Infant, you must also have a deep understanding of the teleportation technique, plus your understanding of the space technique, it's time to make that attempt!"

The voice of the master Soul Heaven came, which immediately reminded Long Fei and reminded him of this incident.

The art of teleportation can be said to be a very powerful spell, and its biggest feature is that it can disappear at any time, and it can appear at any time.

If this teleportation technique is applied to the battle array, then he can lead the team to appear anywhere on the battlefield, and can disappear again when there is danger.

If this idea is realized, then the combat power of the blood blade will become extremely powerful, at least everyone's lives are not worried, and they can escape at any time if they can't fight.

Thinking of this, Long Fei started the retreat again, found all the books on space and teleportation in the soul chain, and Long Fei began to enlighten.

In the final analysis, the technique of teleportation is to use the Yuan Infant to wrap the body and use the power of space to achieve a closer distance.

It's like a gate, you can open the door and you can enter, but if you choose to take a detour, then the distance becomes farther away.

Time passed day by day, about a month or so, Long Fei read all the books carefully.

The next step is to keep thinking, try at the same time, and carefully feel the moment of teleportation.

"Coercion, carrying the body through space...... Traveling through space...... Well, how about that?"

Long Fei suddenly grasped the point, if he used his spiritual power to wrap the object, he might be able to take it away with him.

As soon as he thought of it, Long Fei took out a flying sword, wrapped it layer by layer with his perception, and then launched the teleportation technique.

"Brush ......"

Long Fei's body appeared in the distance, but he didn't care in the slightest, but stared at the flying sword wrapped in perception.

"Well, it's still inside, which means it's okay!"

Long Fei's face showed surprise, and all the knowledge in the books he had seen before appeared at this moment, making him understand it thoroughly.

"If I blend into the battle formation, that is, wrap all the people in it, so that I can teleport, they will definitely disappear with me!"

Long Fei thought about it secretly, figured out this, and then it was time to try.

Long Fei took out a transmission note, passed the order, and then he went out of the lair and outside.

About two minutes later, Reiwa and his team also appeared outside.

"My lord, everyone is here, is there any more mission?"

Ling He asked in surprise, after cultivating here for so long, his hands were already itchy.

"There is no mission, I just have a new innovation in the battle line, if it can be successful, the survivability of our team will be greatly improved," Long Fei explained.

"What is it to improve combat effectiveness and survivability!, my lord, just tell us quickly!" Reiwa said eagerly.
