The whip-like scale tail quickly drew towards the retreat of the four-winged golden lion, and even the space was filled with a little ripple, which showed the power of this blow.

His eyes flashed with thunder, and there was a touch of disdain in Lei Qi's eyes, and a golden tail flashing with thunder met the blow of the Bloodtooth Demon Dog. At the same time, a huge purple thunderball from his mouth blasted towards the Bloodtooth Demon Dog.

The two tails struck each other, and the space rippled layer by layer, looking at the thunderball that attacked, a ball of light emitting evil black gas also appeared in the mouth of the bloodtooth demon dog, and it met the thunderball. The two collided, and a huge explosion occurred, and a dark spatial crack spread out from the center of the explosion like a spider web.

The battle between the two holy beast-level source beasts, although the aftermath generated by it will not shatter the space, but the powerful energy and scattered energy can also explode the space, and the storm is bursting within a radius of a thousand meters, and Ming Mo is quietly watching the battle between the two beasts motionlessly with starry eyes on one side, as if he has not been affected in the slightest.

And through this moment of observation, Ming Mo found that the strength of this blood-toothed demon dog was actually a fifth-order intermediate source beast, which was much stronger than the four-winged golden lion.

Although Lei Qi's strength has been trained for three years, it is infinitely close to the fifth-order intermediate level, but it has not yet broken through the fifth-order intermediate source beast, although the strength is comparable, but Lei Qi is still weaker after all, and it looks comparable in a short time, but after a long time, the disadvantages will be revealed.

"I didn't expect you to be a fifth-order intermediate holy beast, but my old Lei is not a vegetarian, take me again!"

With a blow to the Blood Fang Demon Dog, Lei Qi was shocked back two steps, at this time, he also clearly knew the level of this Demon Dog, and he wanted to solve it quickly.

With a roar, on Lei Qi's golden body, purple thunder light continued to flicker, and at the same time, a huge momentum spread, turning into a cold wind, dark clouds gathered in the dim sky, in the clouds, electric snakes loomed, a powerful power enveloped this area, Lei Qi's golden wings have been covered by thunder, completely turned purple.

The purple thunder light continued to converge, from the extended four wings of the continuous convergence, gradually, a purple huge thunderball appeared in the sky above the four wings of the thunder, this thunderball is completely different from the previous one, not only bigger, but also more powerful, in the sky, one after another thunder snakes slashed down, absorbed by the purple thunderball, the breath is even more terrifying.

And feeling this powerful aura, the disdain in the eyes of the Blood Fang Demon Dog finally disappeared, turned into solemnity, roared, and the black gas on his body continued to surge out, in his mouth, a pitch-black ball of light was constantly converging, and the black gas poured into his mouth, absorbed by the ball of light, and then continued to compress and rotate.

"Let you taste my strongest blow!"

With a sneer, above the four wings of the thunder lion, a purple mark appeared, and the thunderball in mid-air turned into a purple thunder pillar and blasted towards the Blood Fang Demon Dog.

As soon as it was struck, the wind and clouds changed, the purple pillar of light thundered and lightning, and the space was shattered, and the violent energy contained in it made the Blood Fang Demon Dog change color slightly, and a pitch-black pillar of light burst out from its mouth, colliding with the thunder pillar.

The most masculine and rigid thunder and lightning collided with the cold and dark dark source force, the two extreme forces continued to attack, wear each other out, and in the center of the collision, the dark spatial rift spread, stunning people's hearts, and finally the two comparable forces were annihilated together, while the thunder and the bloodtooth demon dog were shocked back a few steps.

"Hmph, I didn't expect that even my strongest blow could follow, worthy of an ancient beast, suddenly strong!"

Lei Qi looked at the Blood Fang Demon Dog with some breath, the surprise in his eyes was undisguised, he didn't expect that his strongest blow would actually be followed by the Blood Fang Demon Dog intact, which greatly exceeded his expectations, even if it was a fifth-order intermediate holy beast, it was rare to take his blow unscathed.
