"Then let's do it!" Luo Changqing could only agree.

"The entrance to the tunnel is still some distance away from the Heavenly Tree to the south, I'll let you know when it's dug up! I'll get you a map later! Mu Zhenwen left after speaking.

The tunnel will not be dug until tomorrow, and Duan Li'er also plans to take advantage of this time to cultivate well to see if he can break through the foundation building period and reach the knot stage.

Luo Changqing also planned to consolidate his cultivation.

So they all went back to their own break rooms.

Duan Li'er sat cross-legged on the cyan floor, her eyes closed, she looked inwardly at the situation in her body, and began to operate the door of life and death!

At this time, her three crystals have been fused into one, and when she cultivates, she also cultivates at the same time, so it is much slower, when she absorbs the aura, one enters the small crystal of physical energy, one is absorbed by the green soul, and the other is absorbed by the thunder soul!

There are also two crystals at the same time, and there is no breakthrough in the previous order.

If she breaks through to the Dan stage at this time, her strength will definitely soar, but it is not easy, she is like cultivating two crystals, she also found that those small crystals only absorb the aura of the fire attribute, and the rest are absorbed by the big crystals, of course, the thunder attribute is still absorbed by the purple soul, and after the white aura is refined, it also becomes the power of the soul and rushes into the sea of spirit.

She wondered what would happen if she had a crystal in her mind.

Late at night, Duan Li'er opened her eyes and sighed, at this time she was only a thin line away from breaking through, but she couldn't break through no matter what, she had to look at the timing!

So I turned out the resolute knife duel and arrogant wind finger in my mind! Now that her soul power has reached the standard, she can also cultivate more advanced sword skills and fingers.

She has already cultivated the upper part of the second layer of the Yi Sword Duel, mainly to control the power, using the power of the soul to cooperate with the sword technique to swing out the power of the soul, and the second half is to use the sword technique and the power of the soul to release terrifying attacks, just like Luo Changqing's sword skills.

The back part of the second layer also has only two sword skills, "Soul Breaking Strike" and "Extreme Perseverance Nine Strikes"!

After seeing these two tricks, Duan Li'er was also stupid in his heart.

"Soul Breaking Strike" is specifically for attacking living souls, he is even more domineering than soul power slashing, extremely fast, even if he uses a magic weapon to block, it will hit the magic weapon and explode.

"Nine Strikes of Extreme Perseverance" is a set of close-range attack knife skills, with a total of nine consecutive blows, one blow is more than twice as strong as the other, but with Duan Li'er's current cultivation, he can only perform three blows, if he wants to completely use the nine blows, he estimates that it will be to the Golden Immortal Period!

The next morning, Duan Li'er, Luo Changqing, and Mu Zhenwen were all sitting in the hall, discussing together how to take out the black ball more safely!

"Those barbarians can release a red light to sense the surrounding environment, and their spiritual power is not very strong!" Duan Li'er said.

"That red light can only be released once a day, and the coverage area is determined according to the size of the strength, and under normal circumstances, they will not release it!" Mu Zhenwen said.

"We plan to start the operation tonight, how is their combat effectiveness at night!" Duan Li'er asked.

"They have to rest at night and rarely go out and walk, we don't know, but it should be weaker!" Mu Zhenwen thought for a while.

"Wood Patriarch, how strong is their patriarch? 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! This is also what Duan Li'er is most worried about.
