The defense towers were all destroyed, although it was expected, after all, no matter how powerful the defense towers were, the energy in the hedron was not infinitely supplied, and the Sea of Skulls had 30 million in number, but it was only on the fourth day that all the defense towers were destroyed, which was still a little earlier than everyone imagined.

"Let's get started!" Haoren sighed and turned to Lin Tingzhi and said.

Lin Tingzhi nodded, he had planted a large number of bombs around the defense tower according to Haoren's instructions, which was prepared for this moment.

Losing the support of the defense tower, the skeletons rushed over brandishing bone knives, and then only heard a few dull explosions, and the ruins of those defense towers on the ground suddenly spewed out streams of azure gas, and the gas quickly spread across the battlefield around Hope City, and soon completely covered the area within a radius of kilometers.

The running skeletons were caught off guard, and after being contaminated with blue gas, a layer of white and crystal ice slag began to spread from their feet, quickly enveloping their entire bodies in the shiny ice, immobilized in place.

"It's nitrogen!" Tang Lin couldn't help but be surprised.

"That's right! Nitrogen mines, the golden skill I've recently learned, can plant nitrogen-vaporized mine bombs, and everything will have to freeze me after exploding! Lin Tingzhi was quite proud.

Then Lin Tingzhi detonated an ordinary bomb, and in the explosion sound of this time, countless frozen skeletons and ice cubes were blown into pieces, and the ice cubes gradually melted into water in the high temperature burning, making the entire battlefield like a river passing by.

This little episode didn't stop more skeletons from pouring in, but Lin Tingzhi's trap bomb was clearly more than that. I saw his hands pressing quickly on a certain device, and soon a disc-like saucer came out of the ground with a "whoosh", spun and flew rapidly in mid-air, and a series of sizzling electric sparks emerged from the surroundings, the electric sparks fell into the wet ground, and the current conduction quickly spread throughout the field, and the elemental resistance of these skeletons was almost zero, and the current passed through the whole body, and immediately convulsed, and they fell to the ground one after another. The soul flame in his pupils gradually dissipated.

"Well done!"

Everyone simply complimented. After two rounds of traps, the losses of the Death Legion increased slightly, but then came the real battle, and the real siege began.

The walls of Hope City were built very high. And it is composed of insulating ore. But these skeletons in front of them didn't even possess sword energy. So the insulating mine doesn't have much effect.

The archers at the head of the city began to unleash a massive and dense rain of arrows, a silver magic that could instantly consume a large number of arrows and deliver high-intensity strikes to enemies within a certain radius. And the golden upgrade of this magic also exists, called the Phalanx Burst Arrow Rain, which has a wider range, faster shooting speed, stronger attacks, and an explosion effect.

But the magic consumption of the burst arrow rain is also very terrifying, almost four times that of the arrow rain, so considering it, Qin Yang, the leader of the archers, decisively chose to use the ordinary arrow rain to carry out a salvo attack.

Magicians do the same, choosing the Silver Sea of Fire instead of the Gold Sea of Hellfire, or the Silver Blizzard instead of the Gold Super Blizzard. Even the few dozen large skeletons that remained were not spared by the constant repetition of silver magic and arrows.

The siege began with a one-sided slaughter, and the skeletons once again showed their fragile bodies to the fullest, and if you didn't take into account the difference in numbers, the battle really didn't have the slightest suspense.

The slaughter lasted until dusk and ended, after leaving hundreds of thousands of skeletons, the Death Legion chose to retreat earlier today, and everyone seemed to have found a certain pattern, although the skeleton soldiers were completely tireless and painless, and did not need to sleep or resupply, but there always seemed to be a certain time every day when these skull seas were in a state of immobility.

But this also proves once again that there must be a certain manipulator or group of manipulators behind these skeletons, although the skeletons do not need to rest, but the manipulators behind them may not be.

Then it was the fifth day, and what made everyone feel strange was that the Death Legion was very quiet throughout the day, besieging but not attacking, of course, Haoren used the Supreme Sword Technique as usual, but it didn't arouse much resistance.

On the sixth day, when everyone was a little drowsy, the Death Legion finally made a move, and the initial charge was only to send them to death as always, and after everyone had recuperated for a day, the offensive became more violent, without giving the skeletons any chance to get closer.

But an hour later, the situation was a little weird, and after those white skeleton soldiers were almost dead, the skeletons that followed after were all holding a bone shield in front of them.

"Uh, evolved?"

"What are you doing, prepare for the rain of arrows!"

A storm of arrows fell, but this time the effect was far less than just now, the defense of the bone shield was stronger than everyone imagined, and the subsequent blizzard did not achieve a greater effect, these bone shields even had a certain ability to resist demons.

Everyone couldn't help but change color slightly, Haoren took a deep breath and shouted, "Super Blizzard and Burst Arrow Rain Ready!" Prepare for those who have these two golden skills! ”

Now was no longer the time to save mana, and the even more bitter cold winds of the super blizzard soon descended, and this time even the skeletons with the bone shield block were frozen into ice in an instant.

And the rain of bursting arrows set off a huge explosion wind on the battlefield, and the bone shield was quickly blown apart, and the destructive power of the golden magic far exceeded that of the silver level, and the skeleton soldiers' defense was useless at all.

The city was briefly cleared again, but as the magicians and archers quickly ran out of magic, the skeletons finally arrived after half an hour.

"I'm going to see how these skeletons get to the city!" Yang Feng held the shield and scolded.

"Look!"

"Holy! That's fine, too! ”

The skeletons under the city side by side, actually began to set up a human ladder, in the blink of an eye, almost reached the city wall halfway, the counterattack on the city head finally began, everyone began to desperately use their skills to go down the city, and the warriors held shields, because the bone spears were thrown towards the city in large numbers, in fact, these bone spears with ordinary attack power were not very threatening, and basically could not cause any losses.

Haoren was covering everyone in mid-air, and his terrifying lethality was basically guaranteed to allow the skeleton soldiers to come and go, and this wave of offensive still ended without a problem, and after the initial exclamation, the skeleton soldiers retreated like a tide.
