The time limit of this secret realm is a total of seven days, and after Xu Feng simply adjusted his state, he planned to use the Heavenly Book Martial Spirit to explore, and as soon as his mind moved, a golden light appeared on the surface of his body.

Since devouring the Shadow Martial Soul, he had found that the Heavenly Book Martial Soul's sensing ability had become even stronger, and at this time, the light guided him in one direction.

There is no doubt that there must be a secret treasure hidden over there.

The golden-winged Dapeng martial spirit appeared, and Xu Feng practiced flying while heading to guide the direction.

Pounce!

His speed increased to the extreme, his wings flapping behind him, and in a moment his figure rose from the ground, but after a few breaths he fell from the air again.

"It's so hard to fly!" Xu Feng complained, but he didn't expect that it would be difficult to fly with his wings.

Then he remembered the process of the chick learning to fly, and the image of the big bird pushing the small bird off the branch flashed in his mind.

He also accidentally awakened the skill of gliding when he first teleported, and it seems that if you want to be familiar with the feeling of flying, you have to glide, and it seems a little difficult to take off directly on the ground.

However, Xu Feng still insisted on practicing for a long time, and after dozens of exercises, he was able to take off a lot longer, but he still couldn't really fly.

"Alas!"

Xu Feng let out a long sigh and planned to give up first.

At this time, a cave appeared in front of him, Xu Feng planned to enter it directly, but remembering the black fish before, he had a long memory, and first used his divine thoughts to explore into the cave.

The cave was extremely humid, and the water above the cave was dripping and ticking, and the cave was relatively narrow at first, and the further you went inside, the more space there became.

Then the divine thought continued to go deeper, and at this time, a black shadow suddenly flashed, and then a terrifying lightning flashed, and Xu Feng's divine thought was instantly defeated.

Airplanes!

A roaring sound sounded in Xu Feng's mind, and he secretly said in his heart that it was dangerous, but he didn't expect that there were really demon beasts lurking in this cave.

If you enter rashly just now, you may be attacked by demon beasts.

This monster beast is less than a meter long, its eyes are the size of mung beans, its tail is long, its hind limbs are long, and its two claws on its forelimbs are extremely long, a bit like a praying mantis, except that each of its front claws is a pair of sharp claws.

"It's supposed to be a thunderbeast!" Recalling the lightning rays just now, Xu Feng concluded that this was a thunder beast, and it should be a thunder and lightning phantom beast born from the thunder and lightning in the sky.

Roar!

There was a roar in the cave, Xu Feng's expression was awe-inspiring when he heard this, he summoned the sword martial spirit, pulled out the heavenly sword behind him, and the momentum on his body was released, ready for battle.

With a sensational sound, the thunder beast rushed out with a bolt of light, and when it saw Xu Feng, it instantly slaughtered Xu Feng, its mouth opened, and a ball of thunder and lightning spit out and bombarded Xu Feng's head.

"Drink!"

Xu Feng snorted lightly, and hurriedly flapped his wings and retreated.

Rumble!

The place where he was standing just now was instantly blasted open a large crater, and dust flew everywhere on the ground.

Xu Feng frowned, this thunder and lightning bombardment was terrifying, it actually contained a trace of thunder and lightning order power, this thunder beast actually had the attack means of the Martial Sect realm!

This level of demon beast can already be called a spirit beast, much more terrifying than ordinary demon beasts, this is a little troublesome, I didn't expect to encounter a strong enemy in the first battle of entering the secret realm.

Roar!

The thunder beast roared, its hind claws slammed on the ground, and then burst out from the spot, and its entire body seemed to turn into a thunderbolt, bombarding Xu Feng again.

Woohoo!

The thunder light swept through the void, and it was as if the air was on fire, and a terrifying scorching breath poured into Xu Feng's mouth and nose, which was a little pungent, making Xu Feng nauseous.

"Slash the sky!"

At the moment when the thunder beast rushed towards Xu Feng, Xu Feng also slashed out a sword, and a sword swept out, colliding with the thunder and lightning light.

Rumble!

Xu Feng's figure immediately retreated dozens of meters, hitting a mound of earth, the terrifying concussive force made his internal organs displace, and his mouth spit out blood, and at the same time, the right arm holding the sword was attacked by lightning, and smoke also rose at this time.

"Hmm, that's numb!"

Xu Feng shook his arm, trying to relieve the paralysis in his right arm, but saw that at this time, the thunder beast attacked again.

Yes?

Xu Feng was shocked, and hurriedly summoned the heavenly que, and in an instant, between the lightning and flint, a shadow of a Xuanhuang giant sword appeared, blocking the thunder and lightning that the thunder beast turned into.

Syllable!

A terrifying roar reached his eardrums, causing Xu Feng's mind to buzz.

Forcibly calming his mind, Xu Feng struggled to get up and swallowed a pill into his mouth, with a trace of ruthlessness in his eyes.

This was the second time he had suffered from this kind of attack like thunder and lightning, which was too strong and domineering, not only to attack the body, but also to shock his soul, and to paralyze him if he was not careful.

The Cold Ice Sword Gang burst out, and then the Heavenly Sword in his hand lit up with a cold light.

"Dustless!"

The terrifying ice sword gang quickly intertwined, forming a sword curtain that covered the thunder beast.

The thunder beast turned into a thunderbolt again at this time, and the terrifying lightning continuously tore apart the sword curtain, but the breath of ice also slowed down the opponent's speed.

I saw a fierce light in the eyes of the thunder beast, and the two sharp claws were covered with a layer of thunder and lightning light.

Crackling!

In the next second, two sharp claws slashed through the sword curtain, instantly tearing open a hole in the sword curtain and breaking through from it.

However, the thunder beast also left many sword marks on its body at this time, which shows that this kind of attack on a dense range is difficult for even the thunder beast to resist all.

Seeing this, Xu Feng had an idea in his heart, since the front was just right, then use the cold ice sword gang to attack in a large area, and grind the other party to death!

"Whew~"

The thunder beast seemed to sense the danger, and suddenly raised its head to the sky and roared, like a wolf howling.

Seeing this, Xu Feng couldn't help but have a sense of crisis in his heart, this kind of voice was a bit like summoning companions, thunder beasts all inhabit in groups, if the other party summons companions, it will be troublesome, he may have to explain here today.

"Humph!"

Xu Feng snorted coldly, and then broke out again, and a cold ice sword curtain covered the thunder beast again, and then turned around, fluttering his wings and retreating towards the rear.

Zizizizi!

The thunder beast broke through the sword curtain again, but the injuries on its body were even more aggravated at this moment, especially on its hind legs, at this time, a cold ice sword gang was raging in it, and a lot of purple blood flowed out of the wound.

But Xu Feng was running away at this time, the other party was gathering his companions just now, and if he didn't run at this time, it would be too late for more thunder beasts to come.

It's just a pity, just now he had the opportunity to kill that thunder beast, but he didn't expect the other party to be so cunning and gather his companions.

Sure enough, it is a spirit beast, it has a certain amount of intelligence, and if it can't be beaten, it will call people, and it will not have no strategy like ordinary spirit beasts. Xu Feng sighed secretly in his heart.
