The last day, of course, could not learn anything new, and he compared the memories in his mind with what was on the wall to see if there were any errors. If there is confusion in the memory, use the jade slip to write it down, and remember it side by side.

Han Yu spent most of the day to get this matter done, and only after confirming that it was correct, did he put his mind at ease.

At this time, only a little bit of fine sand remained in the hourglass, and it was still slowly passing.

When the last drop of sand shuo flowed in, suddenly a crisp bell rang from nowhere, and the sound was long and pleasant, like fairy music. Han Yu stuffed the jade slip into the storage bag and waited for the test to come.

Han Yu raised his head and found that the giant hourglass in mid-air had disappeared for some time, and the ground in the center of the hall was "rolling", and the surrounding bluestones were cracked and raised a piece of bluestone the size of a zhang, and the light lit up with a small teleportation formation on it.

Han Yu thought about it and walked over, a burst of light flashed, and Han Yu was teleported out.

When the light was dissipated and teleported out, Han Yu's heart was shocked, the place where he was at this time was actually a strange sea!

But the sea is not calm, the sky is full of dark clouds, the waves are raging, and in the waves below, you can still see huge phantoms gliding by. What's even more strange is that thunder seems to be brewing in those dark clouds, and it is actually raining heavily in the sky.

"This is a formation?" Han Yu frowned.

Han Yuzheng was stunned, and suddenly a crisis surged in his heart, and when he looked down, he saw a strange fish full of fangs jumping up from the waves and biting him fiercely.

Han Yu was shocked in his heart, and wanted to spray the flying sword in his mouth to meet the enemy, but the flying sword couldn't summon it.

He immediately changed his ways, and with a wave of his hands, seven or eight feet long wind blades slashed past, cutting the strange fish into minced meat and floating on the surface of the sea.

The bloody aura attracted more strange fish, and they devoured the corpses of their own kind, and saw humans floating in the sky, so they pounced on him.

Han Yu had already prepared this time, and with a cold snort, he flicked his sleeves, and more wind blades were densely formed around him, and he rushed over with a roar.

But the number of these strange fish seemed endless, and more strange fish poured out of the sea, this time in the hundreds.

Han Yu also realized that there was something wrong with what he had just done, and with a slight touch of his fingers in the depths, three ice walls were formed around him, causing those strange fish to rush towards the ice frantically.

Han Yu didn't fight back, but just used his mana to continue to strengthen his defense, letting these strange fish toss.

I don't know how long it took, but when the strange fish saw that they couldn't break through the ice defense, they turned around one after another and devoured those of their kind floating on the sea.

Suddenly, a huge yellow and black sea snake appeared from the sea, and the triangular snake head was glowing with fierce light, and it opened its bloody mouth and took several strange fish into its mouth.

Han Yu's eyes flashed with coldness, and he stretched out his hands to condense an ice spear of a length of a few feet, and stabbed it fiercely towards the sea snake that was still rolling on the sea!

The sea snake dodged the ice spear one by one, but in the next moment, one of them suddenly let out a terrible scream and pounced on Han Yu.

Seeing an ice spear stuck in his soft abdomen, Han Yu couldn't help but show a smile on his face, summoning a cloud of ice rain to meet him.

Even Han Yu didn't expect that this battle would last all night!

But what was strange to him was that the mana in his body was always very full, and he didn't feel the slightest bit tired after releasing so many spells.

With Han Yu's cleverness, of course, he also guessed that there was an illusion in front of him, and this trial was to test the control of the spell.

He couldn't let go of this kind of opportunity to practice his spells without danger, and the rule should be that he was attacked by a sea beast in the sea, and the trial was over.

Now the outermost layer next to Han Yu's body is a flame light shield composed of flames, the middle is a layer of water curtain, and the innermost layer is a shield composed of cold ice, three layers of protection.

And he has also seen many sea beasts, squid, octopus, crabs, fur seals, manatees, sea lions, and what kind of tiger dolphins, bladefish, all of them.

This continuous battle lasted for three days and three nights, and although the mana in Han Yu's body was still very full, he was mentally a little tired.

Just thinking about it, there were a few muffled thunders in the sky, and the dark clouds in the sky quickly gathered above his head, and Han Yu's face showed curiosity: "What kind of monster will it be this time?"

Han Yu could feel that the monsters on the sea were getting stronger and stronger, and the tiger dolphin that came yesterday was already a sea beast in the early stage of foundation building, and it took him a lot of effort to take it down.

Everything can only be used by spells, and no other attacks can be used, which makes his puppets, flying swords, and spirit objects unusable.

Han Yu's eyes suddenly narrowed slightly, and with the raindrops the size of beans, the wind and clouds on the sea surface surged, forming a constantly churning vortex, as if he was accumulating strength.

Before Han Yu could make a move, a scene appeared in the sea below that Han Yu would never forget.

I saw a giant tree-thick octopus claw deep into the sea, and then a huge octopus that had never been seen before jumped out violently, and several thick walls of flesh slapped towards Han Yu.

Those grinding disc-sized suction cups were densely distributed on the octopus wall, and the scalp of the people watching was a little numb, and they smashed the outermost flame shield, the water shield in the middle, and the close-fitting cold ice all with just one hard shot!

Han Yu's figure came to the sea a mile away with a blur, and Han Yu looked at the octopus with a solemn face. The demonic aura emanating from its body was even stronger than him, and in the later stage of foundation building, it could barely feel a faint spiritual pressure.

"The foundation is complete!" Han Yu breathed a long sigh of relief, and a sense of battle surged in his eyes.

The whole picture of the octopus was revealed, a mountain-like figure, with eight tentacles, slapped the surface of the water violently, and huge waves rose out of thin air beside the octopus, rippling around with rolling might, stirring up a water curtain about three feet high!

In the next moment, the two tentacles of the octopus penetrated the past, but Han Yu's figure blurred and turned into foam.

The tentacles of the octopus fluttered into the air, and he was a little surprised in his heart, but a figure appeared above his head, and more than a dozen wind blades rushed over, but there was a sound of gold and iron resonating on the body of the octopus, and he failed to break through the defense!

Han Yu's face changed slightly!

The octopus was unharmed, but it was furious, and the remaining six tentacles were wrapped around it.

Han Yu used the exercises he had learned on the stone wall to turn to the other side and dodge very easily.

It took a great deal of effort to summon a fiery dragon, and before he could throw it over, the octopus's claws slapped at it.

He had to give up again, dodging the fire dragon three times and finally taking shape, landing on the back of the octopus, the skin on which was somewhat charred.

"It really works!" Han Yu was overjoyed in his heart, and disappeared vaguely again.

Anyway, he didn't have to worry about the consumption of mana under this kind of illusion mirror, but he still took the scene in front of him as real, and burst out the potential of his body in the battle against a strong enemy!

After fighting for half an hour, although Han Yu kept bombarding the octopus's skin with the fire dragon, he could never cause fatal damage to him.

Han Yu looked at the dark clouds that were still twisting in the sky, frowned, and made a bold decision.
