"The Gate of the Molten Heart?" Su Chen frowned slightly, there didn't seem to be any special gate for the Molten Heart in his memory.

"Although the Molten Heart is in the world of Azeroth, due to the transformation of the Flame Lord, it already has the characteristics of some elemental planes, so it cannot be reached directly, but now those fire elements of the Molten Heart can't help but rush out by themselves, which is equivalent to opening the door of the Molten Heart." Onexia laughed.

"Molten Hearts can't go straight in?" Su Chen couldn't help but be stunned when he heard this, he didn't expect that the Heart of Molten Fire would have such a secret, as for the elemental plane, it is estimated that there will be more hidden secrets.

"Yes, in fact, this is also one of the reasons why I was reluctant to make a direct attack before, if my brother and I directly attacked in person, although we could easily defeat those black iron dwarves, but it would make those fire elements in the Molten Heart alert, and even completely close the entrance of the Molten Heart, now they see that only some dragon beasts are coming to attack the Black Stone Abyss, and they must think that they can defeat it, so they take the initiative to rush out of the Molten Heart," Onexia smiled a little proudly, and at the same time pulled Su Chen to run forward quickly.

"Where are we going?" Su Chen asked in surprise.

"Of course it's to enter the Molten Heart, now is the best time for us to enter the Molten Heart!"

"Do you know where the entrance to the Molten Heart is?" Su Chen asked with some confusion, this black dragon princess seemed to be more lost than herself.

"Of course you know, it's where the temperature is highest!" Onexia said as she threw Su Chen into the air above a magma pool.

"You ......" Su Chen was startled, and was about to use that flashing skill to leave this dangerous place, but saw that Onexia had also jumped high and jumped towards this piece of magma.

However, after Onexia leaped onto this magma, she immediately regained the appearance of a black dragon, and its huge wings spread out, just in time to be caught by Su Chen, who she threw into the air.

Su Chen suddenly breathed a sigh of relief, but when he looked down, he couldn't help but gasp, below him and Onexia was actually a river made of magma!

The red lava is rushing endlessly, and the scorching heat wave is daunting.

The huge black dragon began to fly quickly along the lava river, and from time to time fiery red sprays splashed on her body, but the black dragon with the power of the earth was completely unafraid of the magma, and walked straight over the rising magma.

However, this made Su Chen embarrassed, and he had to dodge those magma on the back of the black dragon again and again.

"This is it!" After flying for a while, Onexia suddenly let out a dragon groan, and at the same time increased the speed of the flight.

In front of us was a huge bridge formed by nature, which happened to be erected on top of this lava field, and there were a large number of fire elements on the bridge, and in addition to some guarding and patrolling in place, there were also many fire elements and lava giants that were constantly rushing into the distance.

"This is the entrance to the Molten Heart?" Su Chen looked at the other end of the bridge, and couldn't help frowning, he didn't expect to really see a large number of elemental creatures rushing out of it, looking like they were preparing for a big battle with the Black Dragon Legion.

However, with the arrival of Onexia, those fire elementals and giants also discovered the huge black dragon, and immediately countless fireballs and magma-wrapped rocks roared towards the black dragon.

Su Chen could feel some slight tremors in the black dragon's body under him, and even a large area of flames erupted from the black dragon's mouth, causing a sea of fire in front of him to completely become a sea of fire.

"This 'deep breath' is useless against those fire elements...... Su Chen thought secretly, but the black dragon under him didn't stop at all after spewing out a mouthful of dragon breath, and actually flew directly into the dragon breath that it spewed out by itself.

"This can't be suicide, right......" Su Chen's brows jumped, and he hurriedly turned on his magic immunity ability.

Although he was not harmed, the experience of passing through the sea of fire still made Su Chen tremble, and the endless flames surrounding his body were enough to make people feel suffocated.

At this moment, the black dragon under him suddenly heard a violent vibration, almost knocking him down.

"This dragon knight is really not easy to be." Su Chen was sneering in his heart, but his face changed suddenly.

Although there is still a sea of fire around it, the brain has already provided a scene that has been synthesized through analysis.

Only then did Su Chen realize that Onexia had actually used the influence of those flames to directly use the dragon's claws to kill a lava giant and a huge fire elemental guard.

The black dragon's melee ability is definitely the first among the five-colored dragon clan!

In just a split second, Onexia had already sladen the very powerful Lava Giant, and even killed a nearby fire elemental, clutching an oval-shaped stone with a glowing red light in its right claw.

"Is that the core of the Lava Giant...... These giants should probably be called molten core giants......" Su Chen thought secretly in his heart.

The combat power of these molten giants that rushed out of the heart of molten fire was much stronger than the lava giants they had seen in the Blackstone Abyss before, but they were still vulnerable in front of the black dragon.

Su Chen carefully looked at the corpse of the molten core giant on the ground in order to confirm the original location of the core, so that he could use the Frost Sorrow sword to stab the core of these molten giants in the future.

However, at this moment, the other fire elementals and molten giants around them had already surrounded them, trying to attack the black dragon and Su Chen on its back.

Su Chen quickly saw the combat power of the black dragon when it broke out in full force.

The huge black dragon can be used as a weapon almost all over its body, and the dragon horns, dragon claws, dragon teeth, and even the dragon tail have powerful attack power!

In just a few minutes, all that remained around Onexia was the corpse of a giant who had fallen to the ground and the remains of the fire elemental.

"It's vulnerable!" Onexia let out a low laugh, but at the same time, she didn't forget to let Su Chen sit still, and then continued to rush forward.

Su Chen only felt that the temperature around him was rising sharply, and the paladin armor he was wearing was even faintly red, and even the rock wall in front of him had become a fiery red, as if it would melt at any time due to the high temperature!

"Is this the true heart of molten fire......" Su Chen exclaimed in his heart, and at the same time sighed with emotion.

At present, among the armies under his command, it is estimated that only the Knights of the Black Blade and the group of Syvarra Demon Priests led by Shahras can enter this place to fight, and as for the other troops, it is estimated that they will not even be able to withstand the temperature of the entrance of this molten heart!
