The reason why Su Yu deceived the two Supreme Elders was that on the one hand, he wanted them to take off their guard, and on the other hand, he wanted the two of them to take the initiative to approach him.

Therefore, as soon as they urged, Su Yu immediately said that he couldn't fly fast.

Seeing that Su Yu was standing still, the Fire System Supreme Elder was helpless, so he could only set up a fire cloud and fly towards Su Yu.

However, just as he flew in front of Su Yu, and the distance was only ten meters, Su Yu suddenly picked it up, and raised his hand to slash out. The snow-white sword light flashed, and a sword light wrapped in purple light burst out of the air, slashing at the past at an unparalleled speed.

This knife was definitely Su Yu's strongest blow, and the dual state of Origin Burning and Destruction Mode was opened in his body at the same time, and the space was cut in half with just one sword.

The fire system in front of him was too high, and there was almost no reaction, and his body was directly cut in two, and the incision was neat and smooth as a mirror.

Then the wound spurted out a waterfall of blood, all of which spilled into the sky.

"You ......" Elder Taishang of the Fire System glared, his eyes full of disbelief, but he only had time to say a word before his body was torn to pieces by the spatial crack.

In the end, a reddish ability core flew into Su Yu's hand, and the blood that spewed out became the Blood Emperor's delicacy.

Turning into elbows and armpits, the Water System Supreme Elder couldn't react a little, and it wasn't until the body of the Fire System Supreme Elder was swallowed up by the spatial crack that he suddenly woke up and looked at Su Yu in disbelief.

"You...... How could it be...... How did you become so powerful? "The Elder of the Water System said with infinite fear.

Su Yu didn't even bother to answer, with a big hand, the layers of space folded infinitely, and the palm of his hand directly pierced through the void, grabbing the head of the Elder Taishang of the water system with one hand, and directly pulled the person to him.

"Poisonous Flame!"

"Whew!"

A black flame enveloped the head of the Supreme Elder of the Water System and shrouded down, instantly igniting a skull and turning it into a raging black flame.

"Ahh......h Water Mirror Clone! ”

The Elder of the Water System screamed miserably, and finally roared angrily, and his body scattered into a splash and fell into the sea.

But that black flame also fell into the sea, and it was still burning, and even a black fire ignited on the sea.

A figure in the sea twisted rapidly, and after only a second, it soared into the sky, bringing up an infinite torrent.

But before the torrent could attack in a hurry, it all fell, smashed into the sea, and set off a huge wave.

As for the Elder Taishang of the Water System, at the moment when the torrent fell, his figure also appeared, but his body had been burned to charcoal, and his head had directly turned into white bones.

In less than three seconds, the poisonous flame burned the Elder Taishang of the water system to a dry corpse, leaving not even a trace of life, which showed its horror.

Su Yu immediately stepped forward and dug out the ability core in the body of the water system elder, and then took out the ability core of the fire system elder on the platform. The two ability cores melted together, inhaled into the body one by one, and through the transformation of the Sky Devouring Thunder Snake, they turned into an incomparably pure source of ability and replenished into their own body.

This source of ability fills in, and the source that has just been consumed by the burning ability is immediately full, and the law of ability is actually repaired to a certain extent.

After Su Yu revoked the destruction mode, he only consumed a small part of the upgrade energy to repair his body, which was a hundred times better than the situation just now.

Of course, in the battle with the Eternal Night Demon King just now, Su Yu was hit by a blow, if it weren't for that blow that destroyed the fundamentals, causing the ability to run around and the body would explode, it wouldn't have consumed so much upgrade energy.

However, the two Supreme Elders were no levelless masters, how powerful the origin of the ability was, and the strong origin energy was thousands of times that of Su Yu himself. This kind of ability origin was instilled into it, and Su Yu couldn't digest it at all, so he could only extract these two power sources and fuse them into a huge ability origin planet, slowly orbiting the stellar phantom of the law origin.

And as soon as this Origin Planet appeared, the Upgrade Energy Planet was actually attracted, and the two spheres surrounded each other for a while, merging into one in Su Yu's stunned sight.

What's even more bizarre is that after the fusion of the two planets, the sphere, which was variegated at first, turned out to be pure white, and it was more than three times larger.

Su Yu panicked, and hurriedly took some experiments, but found that there was no difference from the upgraded energy, and the effect was completely the same.

"Damn, it's so awesome, it turns out that the origin of the ability can be converted into upgrade energy!" Su Yu was so excited that he even trembled all over.

Originally, he thought that if he used a little less of the upgrade energy, it would be gone, so he didn't dare to use it easily, and he even had to think twice about the upgrade rules.

But now, being able to use the source of the ability to generate more upgrade energy is tantamount to a shocking discovery.

You must know that upgrading energy is equivalent to universal energy, which can not only recover injuries, but also condense the law, and accelerate the breakthrough of the realm, which is simply omnipotent.

Su Yu was inexplicably excited, and immediately took out all the ability cores accumulated in the space ring, transformed them into incomparably pure ability origins, and then integrated them all into the upgrade energy.

However, this integration, even though there are hundreds of ability cores, the upgrade energy that can be generated is much rarer, and it cannot be compared to the ability origin of the two Supreme Elders.

Su Yu thought about it carefully, and he was relieved in his heart, after all, the two Supreme Elders were peerless powerhouses, and no matter how powerful the origin of the ability was, it was naturally not comparable to those celestial-level ability cores.

However, this major discovery also made Su Yu excited for a long time, with this way, the upgrade energy can be said to be endless, as long as you continue to kill powerful enemies in the future, you can get endless upgrade energy.

Immediately, Su Yu did not hesitate any longer, and immediately let Yuna levitate beside her, while she sat in the void and began to condense the laws in her body.

With the breakthrough of the laws one by one, the law forms in Su Yu's body have all evolved.

The heavenly dragon lightning directly transformed from dark red to gold, and the golden divine dragon roamed the void, covered in golden light, and the divine horse reached the extreme. Its power naturally increased to a terrifying level of 20 times, and now as soon as Su Yu transformed into the Heavenly Dragon Lightning Mode, his strength would immediately soar from 30 million to 600 million.

Followed by the Eternal Divine Tree, the overall strength has become stronger, and the defense has also surged to 4 times, which has fully doubled the defense. Moreover, the Eternal Divine Tree also generated a steady stream of vitality energy, and this vitality energy was all replenished into the origin of the ability, becoming a powerful foundation.

Then there is the Sky Devouring Thunder Snake, which has changed from 3 times to 4 times the amount of energy, as long as it does not exceed four times the energy attack of Su Yu, all of them can absorb and rebound. Secondly, the efficiency of the Sky Swallowing Thunder Snake's energy transformation is also many times higher, and now Su Yu can not only absorb other kinds of abilities, but also absorb some natural energy, and replenish himself by absorbing energy. It can be said that Su Yu can survive for a long time even if he never eats with these natural energies.

Finally, there is the Flame of Poison, which has evolved to become more violent, and in addition to corrosion, decay, and poison, it also produces a devouring ability. This devouring ability is of great benefit to Su Yu, as long as the poisonous flame is blasted into the enemy's body, he can continuously absorb the opponent's cultivation through the poisonous fire.

As for the other fourteen high-level laws, they were all promoted to the second order, and Su Yu fused all of these laws into a furnace, turning into a golden sphere, orbiting the four immortal laws.

Under the rendering of the four immortal laws, these fourteen high-level laws all had a trace of immortal laws, which even Su Yu was taken aback.

You must know that when fighting against the law of ability at the same level, the ordinary law meets the law of immortality, it will definitely be devoured without any suspense.

But when these ordinary laws have the aura of immortality, the result will be different, and when they encounter the immortal law, they will also have the strength to fight.

Now almost all of the eighteen abilities in Su Yu's body have reached the second order, and it can be said that he has truly reached the standard of breaking through the void level.

It's just that Su Yu doesn't have a suitable cultivation method, and even if he wants to break through, he is powerless at the moment.

Originally, Su Yu also inquired about the Blood Emperor's exercises, but what the Blood Emperor cultivated was blood energy, which was completely different from his own lightning ability, and he couldn't be promoted to the Void Level in the same way.

And even if he can be successfully promoted, the effect is completely different, after the Blood Emperor breaks through, it is a smooth road, and after Su Yu breaks through, it is an endless obstacle.

Therefore, Su Yu can only wait now, and can only get the cultivation method first, and then make the next breakthrough.
