Since Xiao Yu opened this burden full of treasures, he has obtained a lot of good things, including refining materials, alchemy medicinal materials, animal skins and horns, various ancient books that record the laws of time, and more importantly, the unknown jade that makes him feel kind.

And at this moment, he finally looked at the last of these treasures, a black wooden box inlaid with colorful crystals.

"It's the last thing, look at this thing so beautifully packaged, it's definitely not going to be an ordinary product, hehehehe. Xiao Yule rubbed his hands and picked up the black wooden box directly.

Xiao Yu held the bottom of the wooden box with one hand, and gently stroked the surroundings with the other hand, feeling the spars around the wooden box in the most direct way.

"Shhhhh Just touching those spars, Xiao Yu couldn't help but be shocked by the energy coming from above.

"This... What a rich fire attribute... As soon as Xiao Yu's fingertips touched a crimson spar, a strong fire attribute aura drilled directly into his fingertips.

A moment later, when Xiao Yu touched those different colored spars one by one, the shock in his heart became even stronger.

Although these spars were slightly inferior to the fire spirit stones he had obtained before, the power of the array attributes emanating from them made the Five Elements Beads in his dantian tremble like joy, as if he had smelled a peerless delicacy, and he couldn't help but want to swallow it in one bite.

"Just touching the decoration on the outside has such an effect, hahaha, it seems that the thing inside must not be simple. For the contents of the box, Xiao Yu's expectations were even stronger.

So, he couldn't wait to open the box, but a powerful anti-shock force pushed his palm away in an instant.

"This... What's the matter? You don't want me to open it?" was caught off guard by this blow, Xiao Yu's bull temper also came up, and he directly put the box on the ground, and used both hands on the top and bottom of the wooden box at the same time, wanting to compete with it in the most primitive way.

"Bang. ”

"No way?"

"Bang. ”

"Come again!"

"Bang. ”

"I'm going, I'm going to me, aren't I?"

However, after failing again and again, Xiao Yu found that no matter how much strength he used to break the wooden box, there was always an equal force of shock to bounce his hands away, and over and over again, this force was no more than no less, just equal to Xiao Yu's strength.

However, just when Xiao Yu was at a loss, Ye Lao, who was sitting in his sea of knowledge and cultivating, couldn't help but let out a displeased voice, and his tone contained a strong taste of "hating iron does not become steel".

"Apprentice, can't you try it with the five elements of spiritual power?"

"Ah, Five Elements Spiritual Power, Master, do you mean that this lock on the box is laid with Five Elements Spiritual Power?"

"Hey... After cultivating the Five Elements Decision for so long, what is this countershock force, don't you feel it?" Ye Lao stopped talking after saying this, I am afraid that he is soothing his injured heart at this time, after all, his only personal disciple is so stupid, who can calm down on whom.

"Okay! However, Xiao Yu, who was on the rise, didn't hear Ye Lao's helpless tone at all.

"First of all!" As soon as the words fell, a strong fire attribute aura erupted from Xiao Yu's fingertips and hit the delicate black wooden box directly.

"Whew... ”

However, there was no fierce collision, and there was not the slightest sound, as soon as Xiao Yu's rich fire attribute aura touched the wooden box, it was like a stone sinking into the sea, and it was directly absorbed by the box, without even a trace of leaking energy.

"Swallow my aura? Hmph! Then I'll let you eat enough and see if I can kill you in the end!" At this moment, Xiao Yu's stubbornness had overcome his reason, and watching the black wooden box swallow his fire attribute aura cleanly, he couldn't help but speed up the operation speed of the spiritual qi pill in his body, and poured more surging spiritual energy into the black wooden box.

After about a stick of incense, the spiritual flow that was originally connected to the box suddenly trembled, and the next second directly cut off its connection with Xiao Yu.

"I'm full, hey, I'm scared you'll suck me dry!" Xiao Yu looked at the situation in front of him, and his heart was not only happy.

"Next!

"Next!Kim!"

"The last one!

About a quarter of an hour passed, and with Xiao Yu's relentless infusion, he finally unlocked the four-layer attribute lock on the black wooden box.

However, in the next second, Xiao Yu was a little difficult, after all, up to now, he had only learned the four attributes of fire, earth, gold and water, and he could only crack the power of the four attributes on the box one by one, but he had not yet mastered the last wood attribute.

"This... What to do... The power of the five elements is still one kind.,And the crack has broken to this point.,I'm really unwilling to give up the previous efforts.。。。 ”

But the next moment, he was in a hurry and came up with a countermeasure.

"Master, Master, the rivers and lakes are in emergency!" Xiao Yu's urgent voice sounded in his heart.

"I know what you're going to do, but I can't help with that. ”

"No, Master, I don't want you to open the box for me, I just want you to borrow some wood attribute spiritual power to use. ”

"I know what you're thinking, but I've told you that I can't really help you with this favor. ”

"Ah, isn't it? When you were attached to me and fought with Fan Xuecheng, didn't you use the power of the five elements very well?"

"This time and that time, if you don't believe it, you can try it. As soon as Ye Lao finished speaking, a force of attributes that Xiao Yu had not yet touched instantly filled his whole body.

"Is this the power of the wood attribute? I didn't feel it when you first used it, but this power is so soft... Xiao Yu was surprised to feel the unknown energy in his body, and he couldn't help but be surprised in his heart.

"The wood attribute originally contains a steady stream of life force, and you will learn this power in the future, but the teacher is still the same sentence, although you can now use the power to operate the wood attribute, but fundamentally this power does not belong to you, and of course it is impossible to help you open this black wood box. ”

"Hehe, if you can open it, you'll find out. Xiao Yu wanted to break the lock of the last layer of wood attributes, although the night veteran said it in front, but now he is like eating a scale, and he is determined to make a final attempt.

"One last time!Wood attribute!Open it for me!" As soon as the words fell, a rich emerald green energy erupted from Xiao Yu's fingertips, instantly hitting the black wooden box.

"Bang!"

However, this blow did not have the effect that Xiao Yu expected, and the black wooden box did not absorb this huge energy, but returned it in equal proportions, hitting Xiao Yu's chest unbiasedly.

This blow was powerful, and with the blessing of the night elder's spiritual power, it was like an iron hammer, smashing Xiao Yu out of a distance of more than ten zhang, and the black wooden box in his hand also fell into the mire.

"Ahem... Ahem, ahem... Xiao Yu was caught off guard by this blow, and a sharp pain suddenly spread from his chest, instantly spreading all over his limbs.

The originally gentle wood-attribute spiritual power was like a wild horse, rushing left and right in his body, trampling on his still immature and fragile meridians inch by inch.

After a while, Xiao Yu couldn't help but spurt out a mouthful of black blood.

The severe pain lasted for about a cup of tea before slowly subsided, and Lang Ning, who was originally guarding Xiao Yu's side, was unable to approach Xiao Yu because of the raging wood attribute aura.

It wasn't until the surrounding aura gradually subsided that Lang Ning couldn't wait to run to Xiao Yu's side and gently subdue him.

"Poof!"

As soon as he sat up straight, Xiao Yu involuntarily spurted out a mouthful of black blood again, which also made his internal organs feel a trace of comfort that he had not felt for a long time.

"Ahem... It's really exciting this time... Xiao Yu gasped for breath, coughed up a few mouthfuls of black blood from time to time, and finally shook his head and said helplessly.

"The host... What about your final blow... Why is it so fierce? Lang Ning was puzzled in his heart, if he only looked at the energy released by Xiao Yu just now, even if he couldn't reach the level of the Martial Emperor, at least he would be at the top level of the Martial King, but at the moment, Xiao Yu had just entered the Great Martial Master, how could he have such a strong and powerful energy.

"Ahem, I'll tell you about this later, help me up first. Of course, it was impossible for Xiao Yu to tell Lang Ning about Ye Lao, after all, this was the biggest secret in his heart.

Xiao Yu slowly stood up, and with Lang Ning's support, he walked back to the black wooden box step by step.

"Hey... I really regret that I didn't listen to Master just now... It's okay now, all the work has been lost. Xiao Yu looked at the black wooden box lying quietly on the ground, and there was a kind of remorse in his heart.

Moreover, the locks of the four attributes that had been opened by Xiao Yu had now returned to their original state, which meant that everything Xiao Yu had just done had become useless.

"Apprentice, you have the essence of the gods to protect you, this little injury is nothing, and the teacher just now deliberately wanted to let you have a long memory, so that you were instilled with such a powerful wood attribute power. The voice of the old man sounded faintly in Xiao Yu's heart.

"Ahem... Master... Even if you want to teach me, don't be so ruthless, although I can't die this time, it's not comfortable. Hearing Ye Lao's words, Xiao Yu couldn't help but sigh in his heart.

"What the teacher wants to tell you is that you have to rely on your own way to break through, and you can't rely on external forces for everything, just like today's black wooden box, haven't you noticed that if you want to open it, the power of the five attributes must have the same root and the same origin?"

"Hey... I didn't know just now... Right now... The apprentice was taught... Xiao Yu knew that Ye Lao was for his own good, so he accepted it humbly.

However, just as Xiao Yu had just opened the lock of the first layer of fire attributes, the old man who was in the deep retreat of the mountain behind the Blue Lotus Sect suddenly shouted, and then he flew towards the valley where Xiao Yu was.

"Who is it!Who is playing the attention of the Five Elements Forbidden Box!!"
