Shocked for a few seconds, Zhao Jie's face also returned to normal.

Then the content of the class was explained.

This time, the content of his explanation is roughly that killing alien beasts before may produce beast cores.

As well as the scope and method of use of the beast core, most of the beast core can be used as a material for weapon refining, as well as as as an introduction to medicine.

These have been in use since 10,000 years ago, but they have now been discovered more thoroughly.

Yi Tianxing also listened with relish.

Fighting against alien beasts requires not only the strength of the summoner itself, but also some defensive and offensive weapons.

And now that the development and application of these things by the human race have reached the extreme, Yi Tianxing is also very pleased.

"There is less than half a month left for the assessment of the outer courtyard this time, and during this period, I hope that everyone will work hard to cultivate and strive to get a good score in the assessment."

"You also know what the results of this assessment mean, I just hope that you can show your best when the time comes, and you must also have confidence in your own strength." Zhao Jie's words were full of encouragement.

"Yes." All the students replied in unison, and their hearts were extremely firm.

Zhao Jie nodded with satisfaction, and then set his eyes on Yi Tianxing's body.

With Yi Tianxing's current strength, this assessment is no problem at all.

If he had entered the inner courtyard, his face would have lightened.

After all, he is also one of his own students!

Zhao Jie secretly expressed his affirmation of Yi Tianxing, and he was extremely happy in his heart.

After the morning class was over, Yi Tianxing left the classroom quietly.

Head towards the back hill of the academy.

He came to the place where the Sky Swallowing Ant had devoured the corpses of the giant ape and the forest worm before, and found a shady place to sit cross-legged.

Then he pulled out the golden tree and placed it in front of him.

At this time, the Golden Tree was a little drier than it looked before, and the lines on it were much darker.

Previously, Yi Tianxing was loyal to the brachied monster ape in the alien beast forest, and he had already exhausted the remaining soul power inside it.

At the time, he thought that something was wrong, but when he input his soul power into it, it was like a mud cow entering the sea, and there was no response, so he reacted.

If this weren't the case, the powerful beasts he encountered behind him wouldn't have been so difficult to fight!

However, although the Golden Tree lost the soul power that Yi Tianxing had left over from 10,000 years ago.

But it's also a rare material, and its toughness is still extremely strong.

After pondering for a moment, Yi Tianxing took out the crystals that emitted this red shimmer one by one.

As soon as the crystal appeared in his hand, streams of fiery factors spread rapidly, and the air became dry until it was blazing.

The weeds under the crystal also dried up at a speed visible to the naked eye, and finally became charred and even spontaneously combusted.

After a few seconds, the weeds that spontaneously ignited only spread within a radius of about one meter from Yi Tianxing.

A charred black circle also formed under him.

Yi Tianxing only frowned slightly, the energy emitted by this crystal was something he had seen before.

It's just that there are so many more plants here than on that hill, and he's not surprised that this happens.

He then put the crystal and the golden tree together.

The moment it came into contact with the crystal, the golden tree only expanded slightly, and its toughness was enough to resist the blazing heat emanating from the crystal.

Yi Tianxing slowly closed his eyes, and his soul power surged rapidly.

The soul power that emanated directly wrapped the golden tree and crystal.

Yi Tianxing first injected soul power into the golden tree, and at this time, a faint golden light emanated from the golden tree.

Moistened by soul power, this golden tree does not look as dry as before, and its surface is more rounded.

Under the traction of Yi Tianxing's soul power, it also slowly floated into the air and stopped in front of Yi Tianxing.

Then Yi Tianxing input his soul power into the crystal, and the red light emitted by the crystal was even more dazzling.

And this crystal is not at all like the Golden Tree, it contains extremely thick energy inside.

This morning's class also reminded Yi Tianxing that having a powerful weapon can also reduce a lot of trouble for himself.

So he thought of the Golden Tree, and the Red Crystal.

He wants to use the energy in this crystal to strengthen this golden tree and make it into a handy weapon.

"No, I still have this crystal, you can't devour it." Yi Tianxing shook his head and smiled bitterly.

The Sky Swallower was attracted to this thing before, otherwise it wouldn't have moved at this time.

But Yi Tianxing spoke, and the Sky Swallowing Ant quickly quieted down.

Yi Tianxing once again focused part of his attention on the crystal's body, using his soul power to pull out the energy in the crystal little by little.

This is left behind by a level seventy two-headed demon energy fire eagle, and this energy also contains the heat factor of the fire attribute.

However, Yi Tianxing has also absorbed the beast souls of two fire attribute beasts with good strength,

This temperature can't hurt him!

And with the coercion of other kings over all things, the energy in this crystal can only be obedient.

Then, the crystal suddenly became illusory.

The hard crystal became like a liquid with fluidity at this time, and with the traction of Yi Tianxing's soul power, the entire golden tree was like a black hole, sucking the crystal over.

And the red light on Crystal Zhou's body was generous, even a little dazzling.

However, as Yi Tianxing's soul power was pulled and suppressed, this red light slowly dimmed, and the golden tree also swelled sharply.

"Bang!"

After a few seconds, an explosion suddenly appeared in front of Yi Tianxing.

At the moment of the explosion, a small yellow light suddenly burst out of his body and penetrated into his eyebrows.

……

The power of the explosion was not small, and it also attracted the attention of those students on the periphery of the back mountain.

They also turned their gaze to the direction of the explosion.

"What's going on over there? Why is there such a big movement? ”

"I don't know, it looks like something exploded, let's go take a look."

"It's the depths of the back mountain, and there are usually few people going back, so there shouldn't be any strange beasts in it, right? I don't want to go. ”

"What are you kidding, this is the Academy, how can there be a strange beast?"

Some are curious, others are afraid.

However, a few students still gathered and ran to the place of the explosion to find out.

"Did it fail?"

Yi Tianxing waved the smoke and dust in front of him with his hand, and his brows were slightly furrowed.

Fang Cai's explosion, he also quickly cast the soul pet possession, and the black armor on his body was also completely able to resist the impact of the explosion.

After a few seconds, the smoke cleared, and the golden tree was found lying on the ground, and the previous crystal was gone.

The Golden Tree doesn't look like it used to be, it looks bigger overall, the surface is rounder, and it looks more vibrant!

The entire Golden Tree emitted a faint golden light, and this golden air flow lingered around it.

Where this air flow was close to the Golden Tree, there was a layer of fiery red halo, and there was a blazing heat in it!

"It worked!" Yi Tianxing was secretly happy, and directly picked up the golden tree.

As soon as he started it, he felt a blazing heat, and the energy contained in it was also in the crystal.

He poured a trace of his soul power into the Golden Tree, and the two aircurrents on the Golden Tree's body suddenly glowed with two dazzling lights.

At the same time, the golden tree swelled rapidly, as if something was about to burst out of it.

As Yi Tianxing pointed the golden tree in one direction, an extremely powerful impact was instantly shot out from inside, which did not belong to the previous one at all.

The impact directly broke a small hole in the mountain on the side, and the aftermath even radiated to the trees next to it, leaving an extremely deep mark on the trunk, which looked like a huge paw print.

A satisfied smile appeared on Yi Tianxing's face, now that he could use the Golden Tree again, even if he was facing a summoner whose soul power was thirty levels higher than his own, he could also have the strength to fight!

"Who the hell is here to make such a big fuss?"

At this moment, a questioning voice sounded from behind Yi Tianxing.

Immediately afterwards, a group of students appeared behind Yi Tianxing one after another.
