The moment Otto said "Man and rider become one", Balder under Otto raised his head and roared to the sky. The huge roar caused the earth to shake.

Balder's scales trembled, and his four feet touched the ground, continuously absorbing the earth's energy to recover from the injuries on his body caused by Ryan's Thunder Dragon.

The injury recovered extremely quickly, during which time light golden lines gradually appeared on Balder's scales.

As the light golden lines appeared, the ground beneath Balder's feet cracked and magma gushed out.

The next moment, magma from underground rushed up into the sky, enveloping Otto, Balder and the dragon.

From outside the duel arena, all you can see is a huge, extremely thick column of magma.

Standing high in the sky, Ryan saw the appearance of Otto and Balder, and his heart froze slightly. He felt threatened by the lava pillar in the duel arena.

In the stands, many nobles watched in amazement as Otto, who had achieved the unity of man and rider, was called out.

The unity of man and mount: a secret technique that only a very few knights can master. It requires the knight and the mount to communicate with each other and blend their fighting spirit.

Although it sounds very simple, very few people can do it.

After all, how can humans and animals communicate with each other...

Many nobles congratulated the old emperor Art, but Art just smiled in agreement, and the anxious look in his eyes could not be concealed.

This kid Otto...goes crazy as soon as he enters the battle.

I told you a few days ago that this was just a friendly match... How come you've already handed in your rider-rider combo?

Wouldn't they save it for the Eternal Day Secret Realm? Now that it's revealed, how could other forces be unprepared?

Alas... so sad...

In the duel arena, as the lava pillar that enveloped Otto and Balder dissipated, what emerged from it was no longer the shape of a man and a dragon.

But it was 'Half-Dragon Otto'. It was obvious that Balder had already merged with Otto.

Otto's height soared to more than four meters, and the pupils in his eyes turned into Balder's dragon pupils. His long hair, which was originally scattered, was tied into a ponytail behind him, and a dragon's tail was draped on the ground behind him.

The silver full body armor on his body disappeared, replaced by a dragon scale armor made of solid rock. There were lava lines on the dragon scale armor, and hot magma kept flowing inside.

The gauntlets on his hands also turned into sharp dragon claws, so sharp that one claw could take the life of a third-level knight.

The sword in his hand was also covered by the solid rock, turning into a rock spear, with magma flowing in it, emitting a terrifyingly high temperature.

Even the cloudy weather that was changed by Ryan's magic was now dispersed by Otto's momentum, forming fiery clouds in the sky.

At this time, Otto's rank was already... intermediate fourth rank.

"Ryan, the second half is about to begin, are you... ready?" Otto opened his mouth and made a hoarse sound.

Ryan smiled without saying a word, with golden light flashing in his eyes.

The next moment, Ryan entered the Tianyuan state after a long absence. His black hair grew longer and dyed gold, his whole body was wrapped in a golden glow, and a semi-transparent Tianyuan magic ring appeared behind his head.

"Otto... come and fight!" Ryan's voice was obviously very ethereal, as if he was not from this continent, but very divine.

Otto smiled slightly, and the magma in the solid rock spear in his hand flowed faster. With a bang, the ground was trampled into spider-web-like cracks by Otto, and he jumped high.

[Fourth-level fighting skill: Dragon Spear·End Thrust]

Like a missile, he rushed straight towards Ryan in the sky, the spear in his hand was unstoppable.

Seeing this, Ryan snapped his fingers lightly, and nine huge thunder rings suddenly emerged from the dark clouds behind him, standing upright in the dark clouds behind Ryan.

[Fourth-level magic: Heavenly Punishment - Nine Heavens Thunder Ring]

Under the guidance of Lei En, nine thunder rings blocked Lei En in circles.

In an instant, Otto's spear penetrated into the nine lightning rings. The two of them were in a stalemate for a while, and then Ryan's lightning rings disappeared one by one. Otto then rushed towards Ryan.

His speed increased to a higher level, and in almost the blink of an eye, Otto's spear was already in front of Ryan's chest.

But Otto's thrust had obviously consumed most of the energy of the nine lightning rings, leaving him with insufficient follow-up strength. A golden light flashed in Ryan's eyes.

A void base point appeared on his chest, causing Otto's thrust to deviate from its direction.

Then Ryan clenched his hands, and lightning appeared from the dark clouds surrounding Otto. The lightning turned into thick chains, locking Otto who was about to stab into the air.

Although the Thunder Chains did not cause any damage, they were extremely strong, and even the modern Otto would find it difficult to break free from them.
