At least a breather now will be enough for the next wave of attacks.

As long as you can hold on to the point where the surrounding hundreds of miles of the other world are consumed, it will be impossible for the insect tide to form again for a while, this is the only way out for Nancheng at present, and it is also the way out for most other cities.

Another way is naturally to kill the third-order bronze leader, but this requires a strong enough person to do it, at least the third-order must take the lead, and ten second-order existences can help to kill the leader in the insect tide.

But now that the strength has reached the third order, except for Xiao Mu, there is no one for the time being, and it is destined that it will be impossible to copy a similar method in a short period of time.

Moreover, this method is only effective for a single insect tide, and this kind of aggregate of multiple insect tides of Nancheng's age has to be more demanding, Xiao Mu thinks that he can't do it, let alone others.

Half a day has passed, Xiao Mu's true qi has fully recovered, his wounds have healed and scarred, and he has basically returned to his peak combat strength.

And the price was that he used up all the blood energy stored in his body, and even drank most of the S-level nutrient solution.

Thinking of this, he took out a few corpses of second-order alien insects, and after pinching the trick, a cloud of blood and fire fell on it, and began to refine blood energy.

As the flesh of the insect shriveled up, clumps of blood could be refined and he bottled them up.

These blood energies are all essence of life energy, which can be directly absorbed, which can not only restore physical energy, but also repair injuries, which is equivalent to the effect of both healing medicine and nutrient solution.

Theoretically, as long as it's not too badly injured, this thing will work, so he has to keep some on hand.

While refining blood energy, he also shrouded the corpse of an alien insect with his true qi, casting the blood spirit technique, and using the effect of the blood transformation realm to directly absorb its life essence and make up for himself.

His face quickly turned rosy, not to mention that the loss of his previous injuries had been compensated, and his cultivation had improved a little.

Seeing that the elder brother had become vigorous so quickly, Xiao Li'er was a little envious and said: "Brother, why don't I also practice this exercise of yours, I feel like Xiaoqiang who can't be killed." ”

"What are you talking about Xiaoqiang, is there such a metaphor for you?"

Xiao Mu glanced at him angrily: "As for cultivation, forget it, this exercise is a bit evil, I have to cultivate the Five Spirits and Thunder Method to balance, so it doesn't match your physique, let's practice your own exercises honestly, the recovery power is as strong, don't be distracted." ”

"Well, I will."

Xiao Li'er nodded, she was just talking, a little curious.

"Wangwang."

Rhubarb screamed and agreed.

"You can hold these few pieces of blood, and when I have time, I will teach you the spell to extract blood energy, and you can make it yourself in the future."

Xiao Mu handed the three vials of blood energy to his sister, then got up and walked towards the altar next to him.

The altar here is somewhat damaged, but overall it is quite complete, and the lines on it are somewhat like a Bagua diagram, but they are much more complicated.

The Taibai fairy sword in the center is slender and exquisite, the whole body is white and flawless, and it looks very calm at the moment, but the sword body still has a glow, and there are golden ancient words on it, which is the word Taibai.

But the entire sword contains terrifying fluctuations, and the experienced sword qi may explode at any time, and if you get close, you will inevitably be injured.

"Isn't this altar here to keep this sword?"

He muttered to himself, his gaze fell on the lines on the altar, this must be a formation, and it is a formation of not low grade, most of them are also immortal products.

Specially arrange an altar, leaving a formation and a sword, why not take the sword away?

Xiao Mu showed a puzzled look, at this stage, there are very few complete immortal rank and god realm magic weapons, and most of the ice divine arrows he encountered were originally shot out and thrown aside, so they would be missed.

Moreover, the Ice Arrow needs a bow to exert its power, and the effect is single, and the key is that it has already lost too much power.

The immortal sword in front of him is very complete, and the residual power is still terrifying, and it is equivalent to a master in itself.

Why such a complete and powerful sword was left behind, perhaps something can be seen from this altar.

Xiao Mu watched carefully, with his level, he was actually not qualified to study the Immortal Array.

But in the cave mansion left by Lu Dongbin, he has already seen a large number of broken immortal patterns or complete immortal arrays, plus the original accumulation, he still has a little level.

After carefully checking it for a while, he was basically sure that the altar was protecting the Taibai Sword, so that it had not decayed for so many years, and that it could recover so much power after the aura appeared.

"This altar is a bit like a place to charge and refine weapons, helping this sword to recover and make it more powerful!"

Xiao Mu's eyes lit up, and a flash of inspiration flashed in his mind, and he thought of something that was rare, the Refining Array of the Mythical Era!

It is rumored that there are many powerful divine weapons, but it is not enough to create them, and they still need to be polished for a certain period of time to complete.

This requires the assistance of the refining array, and through the power of the formation, the weapon becomes more powerful, which is equivalent to a refining and strengthening process.

What kind of altar is this, it should be a place to refine weapons, once this sword should not have been completed, so it was left behind, and then the aura of heaven and earth dried up, and this formation also played a protective role in disguise, so that the Taibai Sword did not lose too much power.

Later, when the earth descended to the other world, it absorbed the aura of heaven and earth, and the Taibai Immortal Sword at this moment at least had the power of a spirit soldier, so the third-order purple spirit mouse could not be touched.

If you want to forcibly take it, you must have at least fourth-order strength to be possible, or there is a special way to take the sword.

"In the last life, this sword was obtained by Yang Miaoyin, and Yang Miaoyin's strength at that time was definitely not as good as now, if it can be taken away, it must be some ingenious method."

Xiao Mu's gaze changed, thinking back to the information of the Refining Array, and regrettably found that this kind of thing only existed in related legends, and did not describe it specifically, let alone talk about how to use it.

He pinched his forehead, ready to study it slowly, anyway, the alien can't be taken away for the time being.

"Brother, you still look at it, these lines make people dizzy, and you can look at them too."

Xiao Li'er was also observing from the side, but unfortunately she didn't have much foundation, and she couldn't understand the spirit array, let alone the immortal array.

"This formation is very valuable, if you can comprehend half a point, you can use this formation to refine magic weapons in the future, and you can refine it in batches."

Xiao Mu said very seriously, the refining array in front of him can refine immortal weapons, it belongs to the immortal array, and it is a skill to learn a little mystery.

"Is it so powerful? Wait, this is the formation for refining magic weapons? ”

Xiao Li'er was a little surprised, she didn't expect that the formation like an altar in front of her was a thing for refining magic weapons.

"Yes, this formation is priceless, it can't be destroyed, and it can be used in the future, this is a real wealth, more precious than the sword inside."

Xiao Mu nodded, I hadn't heard of this altar in my previous life, most of it was destroyed by unsuspecting guys, and it was simply a terrible thing.
