"Patriarch Mu, how strong is their patriarch's strength, if the black ball is very important to them, it should be placed in a relatively safe place, and there will be powerful people nearby to guard it!"

"I don't know about this, I have to go to the scene to investigate, their mental power is very weak, and you have a magic weapon to protect you, you shouldn't be detected!" Mu Zhenwen said.

"It seems that I can only do this, I still have to go to practice!" Duan Li'er returned to his room after speaking, and Luo Changqing also went back in a hurry, obviously he also learned new techniques after breaking through.

Although the time was a little short, Duan Li'er quickly mastered those techniques with that solid foundation, and now it was only a real battle, and before he knew it, Duan Li'er and Luo Changqing also walked out of the door one after another, followed Mu Zhenwen down the heavenly tree, and came to the entrance of the tunnel.

The tunnel is very deep, there is a distance of more than ten zhang from the ground, enough for three people to walk side by side, and it is not bad to be able to dig such a tunnel in such a short time.

"When you get to the back, there is only a short distance that has not been dug through, so you have to dig it yourself!" Mu Zhenwen finished speaking, and there were a lot of instructions.

Bidding farewell to Mu Zhenwen, Duan Li'er and Luo Changqing stepped into the pitch-black tunnel with the glowing demon crystal in their hands, and they also remembered the map in their minds.

More than two hours, they have come to the end, they can only dig by themselves, according to the distance on the map, at this time they are already in the barbarian lair, but in the edge of the range, the barbarian's lair is on a piece of red soil, about a hundred zhang wide, surrounded by giant trees, there is a giant tree in the middle, the patriarch of the barbarian lives on the tree, and the other barbarians are staying in some stone houses made of boulders.

Duan Li'er and the others were thinking about where to open an exit, of course, it was best to open it in a relatively hidden place, and it was best to be close to the black ball, but they didn't know where the ball was.

"I'll use my spiritual power to probe first, to see if there are any barbarians around above!" Duan Li'er finished speaking, her eyes were slightly closed, she had to be very cautious, the spiritual power of these barbarians was not strong, but the patriarch of the barbarian tribe was obviously not an ordinary person, of course, she also wanted to release her spiritual power and search for the black ball, but the black ball could not be explored with mental power, otherwise if it was provoked, the consequences would be unimaginable.

Luo Changqing has reached the Golden Immortal Stage, and the demon beasts of the Golden Immortal Period, as long as it is not too much, he can basically handle it by himself, but he is not sure about these barbarians.

"Dig ten zhang to the left, dig ten zhang more slope, it is expected that there will be a lot of weeds at the exit!" Duan Li'er said as he took out his long sword and dug ......

They did not dare to use techniques, lest they alarm the barbarians above, and even below, they were very cautious in digging.

Half an hour later, with their ** strength, they finally dug to their destination, of course, now they also need to open an opening up, and they can get out.

"Changqing, have you ever learned the treasure control technique!" Duan Li'er suddenly asked, if you can control the magic weapon, you don't need to dig it by hand.

"I have two souls, what's the use of learning!" Luo Changqing also knew what Duan Li'er was paying attention to.

"Hey, let's keep digging!"
