Boom! With a deafening bang, the dragon hidden in the black mist finally hit Lu Yao's holy shield, and for a while, the Xuanwu totem on the surface of the holy shield was full of light, and the terrifying dragon was slightly blocked for a moment, but in the end, it still smashed the heaven-level soul technique Xuanwu Holy Shield!

Although the Heavenly Rank Soul Technique was terrifying, it was still slightly inferior to the Natal Soul Spirit, and the black dragon that roared wildly rushed directly towards Lu Yao without hindrance!

"Evil beast, in front of me Lu Yao, it's not your turn to be arrogant!", looking at the giant dragon that pounced with his teeth and claws, Lu Yao didn't have the slightest expression of fear on his face, he shouted, and suddenly knelt down on one knee, and slapped his palms on the ground heavily!

There was another terrifying roar, and a huge head arched through the ground, revealing hideously, and before the onlookers could see the whole picture, it suddenly opened its bloody mouth and faced the incomparably arrogant dragon!

For some reason, seeing the blood-red giant mouth, the originally extremely domineering dragon hesitated slightly, and finally turned his head resolutely and returned the same way as if he was running away!

"Bastard, go back for me, tear Lu Yao to pieces for me!", seeing that his natal soul actually escaped from the battle, Lang Yan was in a hurry, and he didn't care about thinking about what made his natal soul so afraid, so he suddenly stood up and ordered loudly, although this natal soul has evolved a certain amount of wisdom, it still can't get out of the master's control, and was roared by Lang Yan like this, although the dragon trembled, but still had to obey the order, and turned to the giant mouth in fear!

"Strange, the natal soul spirit is already quite invincible, what can scare it like this? Could it be that Lu Yao has also cultivated the natal soul spirit? Impossible, on the creature with a huge mouth, I can't feel any soul power fluctuations, it is definitely not a natal soul, nor is it a soul skill! Looking at the magic circle formed by Lu Yao Shicai on the stone slab, it seems to be somewhat similar to some kind of contract in the legend, could it be that this fierce beast was summoned by Lu Yao sacrificing something?" , Song Li, who was enforcing the law on the sidelines, had already been dazzled, he was also a top master himself, and his cultivation was even more pure than Lu Yao, but this battle still made him secretly addicted, whether it was Lang Yan's natal soul or the unknown creature summoned by Lu Yao, it was not easy to see.

The creature with a bloody mouth seemed to have no eyes, half of its body was still hidden underground, its head was huge, it couldn't see its eyes and nose, and a big mouth occupied ninety percent of the space of the entire head, only to see it inhale hard, and the black fog shrouded in the fighting arena was swept away in an instant, and the dragon with its head and tail was timid, and there was nowhere to hide!

"Up, tear Lu Yao and that monster apart for me!", Lang Yan, who was in a state of madness, couldn't tell the situation at all, he couldn't feel the extremely terrifying aura on the beast's body, and similarly, he didn't think about why his natal soul was so afraid, he just desperately wanted to defeat Lu Yao, for this purpose, he could even sacrifice his life as a price!

The black dragon screamed, but after all, it still didn't dare to disobey its master's wishes, and pounced on the beast with its eyes closed!

The beast seemed to be unable to move at all, but roared angrily and opened its mouth even wider!

Bang! With a muffled sound, Lang Yan's natal soul actually rushed directly into the mouth of the fierce beast!

The beast's mouth closed at a very fast speed, and then, I saw that the beast's huge head was constantly bulging and concave, as if something was struggling inside, and at the same time, there was a tooth-sore chewing and swallowing sound, but everyone couldn't help but shudder!!

"Black Dragon, Black Dragon, where are you, come out for me!", at this moment, Lang Yan finally revealed a trace of panic, the life soul spent countless efforts on his part, he had no wife and no children, this black dragon seemed to him like his own son, but now, the black dragon that was supposed to kill all directions was directly swallowed by a fierce beast of unknown origin for no apparent reason, how could Lang Yan accept it?

"Don't shout, that black dragon of yours has become a gluttonous belly!", Lu Yao smiled cruelly and slowly straightened up, everyone noticed that the flesh and blood of his right hand were blurred, and blood was constantly gushing out.

"Gluttony? You said that fierce beast is gluttony? Impossible, absolutely impossible, gluttony is one of the four fierce beasts that are said to guard the underworld, how can you summon it!", hearing the name of gluttony, Lang Yan's face instantly turned pale, he knew that if there was any existence in the world that could threaten the natal soul, this gluttony was definitely one of them!

Gluttony, is a kind of fierce beast that exists in the legend, it has a cruel temperament, and is extremely hungry for food, almost eats what it sees, and in fact, there is nothing in this world that gluttony can not eat, according to legend, in the underworld, all the great treacherous and evil people, must be chewed by gluttony, the skin and flesh of its imprisonment are chewed into pieces, and the reincarnation of grains is reincarnated. The biggest feature of gluttony is that incomparably large mouth. Legend has it that gluttony does not have any natural enemies, and every gluttonous head is dying because of eating too much!

"There is nothing impossible, with your talent, you can cultivate the natal soul, why can't I summon the fierce beast gluttony? The natal soul, the death of the natal soul, Lang Yan, the death of the natal soul, must be very damaging to you, right?", Lu Yao didn't seem to feel the injury of his right hand, and the expression on his face returned to indifference.

Lang Yan's face changed rapidly when he heard this, he could naturally feel that his natal soul was dying out at an extremely fast speed, but now he couldn't care about the heartache, as Lu Yao said, the natal soul is harming the natal soul, it can certainly bring great benefits to its owner, but at the same time, once the natal soul is damaged, then its owner will pay the price of the origin of life!

Every time Lang Yan felt a sharp pain at this time, his vitality was burning rapidly, he didn't expect that his killer weapon would be easily broken by the other party just after it was revealed!

Of course Lang Yan didn't know that Lu Yao, who still looked extremely relaxed, actually paid a very heavy price, that gluttony was a rare super beast in the world, and it was naturally not an easy thing to summon it and use it for me, even with Lu Yao's cultivation, it was far from being qualified to summon gluttony. It's just that this battle of soul suddenly changed, Lu Yao didn't expect in advance that Lang Yan, who was stupid and dull, actually cultivated his natal soul, and in a hurry, Lu Yao had to sacrifice a finger as a price to launch a death contract that hurt others and himself.

The appearance of the natal soul is the biggest accident in this fighting soul, and Lu Yao was able to launch the death contract at the moment of crisis, which also showed his calmness and decisiveness, if he was an ordinary person, it was difficult to keep a clear mind at that time, even Song Li, who was a bystander, admired Lu Yao's accurate judgment, if it was him, although there was a way to restrain the natal soul, but he would inevitably have to pay a price ten times heavier than Lu Yao!

"Lang Yan, I told you at the opening of this conference that if I meet you in the Fighting Soul Arena, I will definitely kill you!", Lu Yao clenched his right hand full of blood and strode in front of Lang Yan, and the hideous gluttony was still chewing hard, the natal soul is rare in the world, even for gluttony, it can be regarded as a big meal!

"Lu Yao, you are so ruthless, I originally thought that with the natal soul, you would no longer be a threat to me, but I didn't expect it...... I didn't expect you to be really ruthless, if I guessed correctly, the contract you launched at the right time should be a death contract that has been extinct on the mainland for hundreds of years! Most people think that this death contract has been lost, but I didn't expect that you are using this death contract today to devour my natal soul!", Lang Yan looked at Lu Yao resentfully, at this time his face was already extremely difficult to see, obviously, the fall of the natal soul had caused him extremely terrible damage.

"To deal with a ruthless person like you, you can only be more ruthless than you!", Lu Yao smiled and shook his head, if he had a choice, he would not launch the outlaw contract, as Lang Yan said, this outlaw contract has not appeared on the Demon Moon Continent for hundreds of years, the reason is because the damage caused by the outlaw contract to the person who made the contract is random, and at the same time, the creatures that can be summoned by casting the outlaw contract are also random! This also means that some people may have paid a very heavy price, but can only get a very small return, in history, there have been people who have summoned ancient divine beasts at the cost of one ear, and there have been people who have paid for their lives, but only summoned a first-order soul beast without any attack power, Lu Yao can summon a gluttonous beast with just one finger, and it can't be explained with good luck, Lu Yao has his own means to reduce the failure rate of this outlaw contract, but even so, casting the outlaw contract is still an extremely risky behavior, and it is this kind of lifeless adventure that makes Lu Yao face the fierce natal soul, just to pay a finger as a price.

Lang Yan was able to cultivate the natal soul, this was completely an accident that Lu Yao had not considered at all, in Lu Yao's memory, in the huge Holy Soul Academy, only the mysterious dean and several unborn seniors had the natal soul, and Lang Yan was just a first-class master who stepped into the realm of the soul venerable one by one, he was able to cultivate the natal soul, in addition to his own forbearance and perseverance, I am afraid that the most important thing is luck.
