Since the last battle, Lin Han has become the backbone of these people, so when encountering such a major event, everyone invariably looks at him.

Lin Han was also frowning at the moment, with his current strength, he didn't pay attention to the dozen or so sixth-order prison beasts at all, even if there were seventh-order prison beasts appearing, he was not afraid, but this time, the number of beast tides was too amazing, with the defensive strength of the vine emperor city, there was no ability to resist in front of this beast tide at all, the gap in number was too obvious, and fighting hard to defend it was tantamount to using a mantis arm as a car.

"Looks like the plan is going to be advanced!" Lin Han was silent, constantly thinking about countermeasures in his heart, originally, he planned to refine the Death Demon Bead after being promoted to the seventh order, but now it seems that he can't wait that long, with his current cultivation speed, he won't be able to reach the seventh order in a few months, if the beast tide is really going all the way north, then, maybe when he will arrive in the vine emperor city.

Although the intermediate base protection system brought back by Lin Han is strong, the consumption is also terrifying, if the beast tide attacks the city with all its might, then, it won't be long before the Yuan Crystal reserves in the city will be consumed, and without sufficient energy supply, the base defense system will not be able to play its due role at all.

For now, only by refining the Death Orb as soon as possible, with the help of the Undead Legion, can this crisis be resolved.

Next, Lin Han quickly issued a few orders, and for a while, the entire Vine Emperor City entered a state of first-level combat readiness, and at the same time, the more than 4,000 survivors who came to defect were also uniformly arranged, and more than 2,000 of them, including He Shaoyang and others, were all included in the battle sequence.

More than 2,000 people formed an independent brigade, their strength was extremely strong, even stronger than the team led by any of the leaders of the Vine Emperor Legion, after all, those who could escape from the beast tide were the strongest among the evolutionaries, including He Shaoyang and Yan Bo, and their team had a total of five fifth-order evolutionaries.

After arranging all the things at the base, it was already the morning of the next day, Lin Han didn't dare to delay, and alone, he took the Yuanneng Flying Boat to the crack where the Death Demon Bead was located.

The distance of dozens of miles, under the condition that the Yuanneng flying boat was at full speed, did not take half an hour.

Coming here again, Lin Han found that the power of death contained in the dense fog in the crack of the ground was even more terrifying, and standing at a height of 100 meters, he could feel the rich power of death constantly floating upward.

The distance was close, Lin Han instantly sensed the connection between the lost trapped demon lock and him, and drove the flying boat, Lin Han came to the closest place to the trapped demon lock.

He could feel that the trapped demon lock should be here nearly a thousand meters vertically, Lin Han couldn't help but be a little stunned, he never thought that the crack in the ground here was so deep.

Controlling the flying boat, Lin Han stuck his head tightly in the crack, which was nearly 100 meters wide, and the boat could gallop here.

In an instant, Lin Han rushed into the dense fog, these fogs were very thick, if an ordinary evolutionary entered here, he would instantly become blind, because Lin Han had the "Broken Delusion Eye", the impact of the dense fog on him was not great.

Soon it descended to a depth of about 100 meters, and at this time, the surrounding dense fog suddenly rolled violently, and groups of skeleton warriors and skeleton warriors spawned out of thin air in the fog, and then, these skeleton monsters rushed towards him with the rolling air waves of the mist.

In the face of these low-level skeleton monsters, Lin Han didn't bother to pay attention to it at all, the "Aurora Cover" on the Yuanneng Flying Boat was instantly opened, the direction remained the same, and Lin Han rushed into the group of monsters.

The defensive power of the "Aurora Mask" can be hard to receive a blow from the sixth-order prison beast, naturally it is not something that these low-level skeletons can break, as soon as they come into contact, these skeleton monsters are smashed by the flying boat, and Lin Han gallops all the way and rushes deeper.

As Lin Han dived deeper and deeper, soon, the monsters of the skeleton knight, the skeleton mage, the skeleton archer and the skeleton centipede appeared one after another, Lin Han conjured a black magic vine and opened the way in front of him.

The current Lin Han has long been different from what it used to be, these third-order and fourth-order monsters can be destroyed at his fingertips, all the way down, and soon, Lin Han came to a place about five hundred meters underground.

This time, a more advanced skeleton monster appeared, the mist rolled, and more than twenty skeleton vicious dogs appeared in front of him, each of these skeleton vicious dogs was nearly twenty meters tall, and their lantern-like eyes glowed with dark blue undead fire, all of them were fifth-order undead creatures.

The width of the crack in the ground was only a hundred meters, and as soon as more than twenty skeleton vicious dogs appeared, they completely blocked the space of dozens of meters in front of Lin Han.

However, it was obviously impossible for a fifth-order undead creature to stop Lin Han, and the seventh-level "Demon Vine Strangulation" was used by him for the first time.

"Die!" A punch was thrown, and in an instant, a huge storm appeared in front of Lin Han, stirring up the thick fog and pouring down all the way.

After the "Demon Vine Strangulation" was upgraded to the seventh level, it was obviously no longer a melee skill, and the seven golden vine leaves shrank to only more than twenty centimeters in size again, and when the skill was activated, the spiral storm generated extended a hundred meters away, and the power was so strong that it was by no means under the vitality of the seventh-order demon beast.

After the storm, more than twenty skeleton vicious dogs were all torn to pieces, and at this time, a burst of roaring sounds suddenly sounded on Lin Han's head, and when he looked up, the skeleton mage, the skeleton centipede, and the skeleton vicious dog that had condensed again took advantage of his pause to catch up.

The reason why these skeleton monsters are called undead is that as long as they are in the fog, unless their bones are completely destroyed, they are undead beings, which is the real horror of the undead legion.

Lin Han didn't dare to delay, and drove the boat straight down, leaving these undead creatures far away.

When he descended to more than seven hundred meters, ten sixth-order undead creatures blocked his way, this is an undead creature called the Dark Knight, with a horse body and a human face, and it is also a condensed skeleton, each of which is more than ten meters high, and each holds a bone long knife, spear, giant spear and other weapons in his hand.

As soon as these dark knights appeared, they launched one attack after another at Lin Han in the air, spear light, sword waves, spear shadows ......, and in an instant, ten attacks blasted towards him, these attacks, each blow was huge, carrying the terrifying power of the dark element.

Lin Han couldn't avoid it, and once again hit the "Demon Vine Strangulation", after the storm, the two dark knights in the central area were destroyed by this blow, while the other eight dark knights were thrown out by the power of the storm and smashed on the rock wall in the crack in the ground, although they looked embarrassed, but they actually did not suffer any fatal damage.

This is the power of the sixth-order undead! Lin Han's brows furrowed, he obviously didn't expect that the sixth-order undead creatures would be so powerful, and before these dark knights could close together, Lin Han's people and boats were one, and they rushed over like lightning.

At eight hundred meters, Lin Han's sense of the trapped demon lock became clearer and clearer, and Lin Han continued downward.

Nine hundred meters!

A thousand meters!

"Shhh...... That's ......" In about a thousand meters, this unfathomable crack in the ground finally bottomed out, but Lin Han also saw that just below him, on the pitch-black ground, there was a huge bone dragon nearly 100 meters long, and his trapped demon lock had strangely become the most important backbone of this bone dragon.

The shock that the hundred-meter-long ancient dragon brought to Lin Han was incomparable, although the information showed that this bone dragon was just a seventh-order undead creature, and it could still not suppress the shock in Lin Han's heart.

Lin Han tried to control the trapped demon lock through Yuan Li, but found that there seemed to be an extremely strong force that completely suppressed the trapped demon lock, and no matter how Lin Han drove it, it had no effect at all.

Looking at its huge tail that resembled a fish's tail, Lin Han immediately remembered that the trapped demon lock should have been dragged down by it before.

Thinking like this, Lin Han suddenly felt a little afraid, you must know that he was only a fourth-order evolutionary when he lost the Trapped Demon Lock, if at that time, this bone dragon broke out of the cracks in the ground, he would definitely be dead!

As soon as this bone dragon saw Lin Han, he got up from the ground, and rushed over with a swing of his body.

Although Lin Han was surprised by the existence of the bone dragon, he was not slow to make a move, and the "Demon Vine Strangulation" bombarded out blatantly.

This time, the invincible spiral storm finally met its opponent, and although the bone dragon was blown back by the storm, it was unscathed after the storm.

"Worthy of the legendary bone dragon!" This time Lin Han's face finally became solemn, since he entered the crack in the ground, with the seventh-level "Demon Vine Strangulation", he could be called invincible, but he didn't expect that he couldn't help this bone dragon.

Lin Han knew that it was not advisable to stay here for a long time, he had to fight quickly, otherwise, once the Dark Knight chased after him, it would not be easy for him to escape.

Seeing that the "Demon Vine Strangulation" was ineffective against it, Lin Han immediately changed his trick and waved his hand forward, and in an instant, the black Dutian Demon Fire surged out, and the waves of fire were churning, raging at the bottom of the cracks in the ground, swallowing the bone dragon in an instant.

It was Lin Han's spiritual power that was consumed by casting the Dutian Demon Fire, and since the Great Yan Destiny Soul Decisive Breakthrough and the condensation of the Holy Soul Pill, Lin Han's spiritual power had already reached the level of the Holy Lord, but it was limited by his own strength, so he could only exert the peak of the sixth order, or it could be said that it was infinitely close to the spiritual power of the seventh order, but even so, the power of the Dutian Demon Fire was far from being comparable to before.

The surging flames filled almost all the space in this area, and black demonic fires could be seen everywhere in the air and on the ground.

The damage of the Heavenly Demon Fire to the Bone Dragon was obviously much stronger than that of the Spiral Storm, and the Bone Dragon kept roaring and churning on the ground.

"Add another fire to you!" Lin Han's eyes were cold, and he once again cast the "Demon Vine Strangulation"!

At this moment, all the flames in the space in front of Lin Han were absorbed into the spiral storm, and the combined wind and fire slammed towards the bone dragon.
