"Spells can also rebound ......" Li Feng said depressedly, this ice wall is very powerful, not only can reflect damage, but also increase damage, if you want to get the things inside, you need to find a way to bring down this ice wall, the treasure left by the ice goddess is really not so simple.

It is definitely not possible to hit with violence, he has to hang up after a few rebound attacks, and he can't cause damage to the ice wall, so he can only outwit.

Li Feng stood in front of the ice wall, lost in thought, and from time to time he would verify his ideas, hoping to find a way to crack it.

"This is a wall of ice, see if you can melt it away with the Abyss Demon Fire!" Li Feng's eyes moved, and he used all his strength to urge the abyss demon fire in his body to bake this ice wall.

Inspired by the Law of Fire Origin, the Abyss Demon Fire released an astonishing amount of heat, and the temperature of the entire stone cave rose rapidly, and the ice on the nearby stone walls began to melt one after another, and the surface of the ice wall also changed, with some faint signs of melting.

"Whew!" However, as soon as the Abyss Demon Fire had some effect, the ice wall lit up with a layer of cold light, and in an instant, an icy and abnormal cold qi was released from inside, surrounding the Abyss Demon Fire and making a violent impact.

This cold aura was too huge, and it kept coming, and the abyssal demonic fire couldn't resist it, and it was forcibly extinguished after holding on for a few minutes.

"Damn, the Abyss Demon Fire didn't have any effect either!" Li Feng gritted his teeth and said, he was depressed in his heart, and kicked this ice wall hard to vent the anger in his heart, but he was hit very painfully by the force that rebounded back.

He thought about it and started a new experiment, he wanted to test it. The ability of the ice wall to bounce back has always existed. There is still a time gap.

"Bang Bang!" He quickly swung the Ten Thousand Bladed Dragon Yuan Sword. Continuous slashing on the ice wall, hitting, very fast.

"―1230"―1410""―1105" Several consecutive damages came out from the top of Li Feng's head, and several attacks rebounded.

"Xiao Ni, you use your minimum strength to keep attacking the ice wall." Li Feng said to Xiao Ni that he wanted to test whether the continuous attack would always be rebounded.

"Yes, master!" Xiao Ni nodded, her fingers moving slightly. A black lightning bolt condensed out and hit the ice wall, carrying out a continuous attack, flashing with black light, this thunderbolt is very powerful, so you don't have to worry about hurting yourself.

Li Feng had been carefully observing the changes in the ice wall, and he noticed that this rebound effect of the ice wall had always existed, and the thunder and lightning that Xiao Ni had made had not stopped, and all of them had been bounced back. It lasted more than two minutes.

"Stop, Ni." Li Feng said. Let Xiao Ni stop attacking, from the series of tests just now, it can be known that the rebound attack ability of this ice wall has always existed, it is an inherent ability, and there is no interruption.

"As long as you don't attack, the ice wall won't be able to bounce back." Li Feng's eyes flashed, he turned on the effect of the top-level concealment elixir, and walked towards the ice wall, preparing to pass through the ice wall directly, so that there was no need to destroy the ice wall.

However, he walked in front of the ice wall, his body could not move on, and the effect of the top-level concealment potion was ineffective against this ice wall!

Another failure, Li Feng wanted to blow up this hateful ice wall with explosives, he tried several methods in a row, but still had no clue.

Speaking of explosives, Li Feng's eyes lit up, and he muttered: "By the way, the system store has [Super Explosive Bombs] for sale, maybe it can blow up this ice wall!" ”

Without saying a word, he immediately bought a super explosive bomb from the system store and used up 50,000 gold coins, the last time in the process of helping Jiangnan Tianyi do the legendary mission, the team he led used this bomb to blow up the demon altar, which was very powerful.

The cooldown of the super-explosive bomb is five hours, and if you can't blow up the ice wall in one go, you'll have to think of other options.

After installing this super-explosive bomb, Li Feng exited the stone cave, and the bomb exploded two minutes after it was installed, and he had enough time to dodge.

"Boom!" Two minutes later, the super-explosive bomb exploded on time, instantly releasing an incomparably terrifying power, the sound shook the sky, at this moment, the entire stone cave began to shake violently, and a rolling heat wave gushed out from it, containing a large number of ice chips and stones, and the wind swept angrily.

This cave is worthy of being the place where the goddess of ice and snow stores her treasures, and it has not collapsed under the bombardment of superexplosive bombs, and it is very stable.

When the smoke and dust cleared, Li Feng immediately ran into the stone cave and came to the location of the ice wall before, and he was pleased to find that the ice wall had been blown up and shattered all over the ground.

Overjoyed, he immediately ran towards the stone cave, but at this moment, a large cloud of cold air emerged from the depths of the stone cave, which quickly condensed into a wall of ice and blocked him in front of him.

"Damn, could it be that this ice wall is infinite, and it will appear if it is broken!" Li Feng was a little dumbfounded, and finally blew up an ice wall, but he didn't expect another one to appear now.

Maybe this wall of ice isn't as powerful as it used to be...... Li Feng comforted himself like this in his heart, and stabbed the ice wall with his sword.

"Ding!" Just like last time, this ice wall also had a strong rebound power, and there was no difference, bouncing back Li Feng's attack.

"It seems that we still need to find the right way to crack it......" Li Feng's eyes sparkled, and he was thinking hard about countermeasures.

He was carefully observing the entire ice wall, and stabbed it lightly with the Ten Thousand Bladed Dragon Yuan Sword, trying to find anomalies in it.

Li Feng's observation ability has always been very sharp and patient, and he is no stranger to this situation, and he has long been mentally prepared to find a way to crack the mystery of the ice wall.

Finally, the hard work paid off, and after more than half an hour of continuous observation, Li Feng found that every time an external force was about to hit the ice wall, some incomparably fine ice and snow runes would appear inside the ice wall.

These ice runes are so small that they blend perfectly with the entire ice wall, making it difficult to spot their presence without looking closely.

Li Feng believed that the rebound ability of this ice wall should be generated by these ice and snow runes, and as long as these ice and snow runes could be destroyed, the rebound power of this ice wall should be eliminated.

This ice wall will regenerate, and it is unlikely that he will have too strong ice and snow power, and with his current strength, he should be able to destroy those ice runes.

After thinking of countermeasures, he held the Ten Thousand Blades Dragon Yuan Sword in his right hand, urged the Abyss Demon Fire with his left hand, adjusted his state, and struck out with his right hand, slashing towards the ice wall with a sharp blade.

At the moment when the ice and snow runes appeared, Li Feng instantly found the right position, and in an instant, the left hand that condensed the abyss demon fire slapped out quickly, and with a roar, it slapped on this position. (To be continued......)
