He stepped out of Chu Yuechan's room and started training his Sharingan, that is, his Mangekyou Sharingan. He asked for some missions from the sect as he wanted to train his combat ability a bit. After waiting for a while, a disciple selected some missions for him to find some Beast cores in Earth Profound Realm.
He jumped on the Snow Phoenix of Chu Yuechan and went towards the Blue Wind Empire; the place where he went was Snow Reign of Extreme Ice. He was extremely cautious along the way as he kept his Sharingan activated. He suddenly detected an attack on himself from his right side. He saw that a someone was throwing Big Blocks of Ice towards them. He knew that the physical power of the Snow Phoenix was very low. If these Ice Block hit it, the ice may break down and it may injure the Ice Phoenix.
Ryusuke smiled as he thought of a perfect way to train, he jumped down the Snow Phoenix and saw that the one who was throwing those was a Snow Wind Great Ape. He sensed that the Beast was also in Earth Profound Realm and its cultivation was actually higher than his own. He picked up a Rock from near him and threw it towards the Snow Wind Great Ape to gather its attention.
After he managed to gather the attention of the Snow Wind Great Ape, he made some Icicles and rotated and threw them towards the Snow Wind Great Ape. The Snow Wind Great Ape stomps the ground a wall of ice was raised in front of it. The icicles crashed on it but were destroyed without even a match. Suddenly, a Huge powerful beam of Profound Energy blasted through the wall and hit the Snow Wind Great Ape.
The Beam was too concentrated and it passed through the Beast and killing the Snow Wind Great Ape in an instant. Ryusuke went forward to pick up the Beast Core that he saw that his Profound Energy Beam had coincidently passed through the Monster's Beast Core which caused it to break apart into little pieces.
Ryusuke was a bit dumbfounded as he started thinking 'Isn't it too much of a coincidence that my Profound Energy Beam passed through the Beast's Energy Core. That mean, it was a waste to fight against it. Oh man, now I have no way to find other beasts in a short term.' He was thinking all this that he suddenly heard the Snow Phoenix's screech and looked upwards and saw that it was fighting against a Wind Thunder Storm Hawk, he saw as the Hawk concentrated a Bolt of Lightning on its Wings and released such concentrated Lightning towards Ice Phoenix.
Ryusuke knew he couldn't reach in time so he quickly used his Mangekyou Sharingan and used "Amaterasu." It caused the Black Flames to suddenly appear on Wind Thunder Storm Hawk and it didn't manage to react in time and was completely swallowed up by his Black Flames within a few minutes. He reached the place where the Hawk's body fell down and saw that even the Beast Core had been burnt down along with its whole body. He thought to himself 'Is it a Coincidence or what the people call as Bad Luck.'
He then asked the Snow Phoenix to go back to the sect as he would come back after the mission. The Snow Phoenix was a bit reluctant in leaving him but it knew that it would only be a burden if it stayed. After staying for some time, it started using its wings and flew away from the Snow Reign of Extreme Ice. After Ryusuke determined that the Phoenix was far away, he finally unleashed his full Aura in the Area. All the Earth Profound Level sensed his Aura and many great beasts felt that it was a provocation against them by this Human who actually released his own aura in their Area.
A Loud Roar was heard in the area and Ryusuke turned in tis direction and saw a Great Sabretooth Tiger coming towards him. Ryusuke guessed that it was at approximately at the Sky Profound Realm and was excited at the prospect of fighting against such a strong Beast. He also rushed towards the Beast using his own speed and body. Both of them struck against each other but the Beast was too strong for Ryusuke and threw him away. He used his Shunshin to go near the Sabretooth Tiger and hit it once again on its body.
Soon, he was about to attack one more time but he saw some Red Electric Sparks from the Claws of the Sabretooth Tiger and made a mental note to use Shunshin at the correct timing, but he didn't expect the Lightning to be so past that he didn't even manage to think of something and was shocked by the Lightning. While being shocked, he tried to absorb some of the Lightning Energy be absorbed into his body but the Profound Energy inside the Lightning made it impossible for him to absorb any Lightning. After a moment, a Large Dark Red Aura started flowing out from him, it formed a humanoid form around his body.
This was the trump card which made him confident enough to fight against the Sky God Realm Beast. His Susanoo, and it was not just an ordinary Susanoo, this Susanoo had the Sword of Totsuka, the Yasaka Magatama and the Yata Mirror. This was Itachi's Susanoo in a similar incomplete form.
Ryusuke didn't use any of the Legendary Weapons against the Beast as it would be too overkill to use even one of them. This time the Susanoo's punch struck against the Sabretooth Tiger and both were at the Equal Power. And Susanoo easily overpowered Sabretooth Tiger and threw him off the field. This caused a Loud Noise in the Area. Many beasts woke up and went towards the place from where they heard the Noise.
There they saw a Humanoid Aura beating a Sabretooth Tiger. Suddenly, 5 wolves attacked the Humanoid Aura who blocked the force quite easily as Susanoo was known much for its Defence rather than Attack. He then looked towards the Sabretooth Tiger and saw another Sabretooth Tiger coming and picking it up. He thought 'Oho, so even these Beasts know how to join hands against a stronger enemy. Looks like I am the target of all the Beasts here. Heh, I wonder who would come out on top after today. Me or all of you Beasts.'
He was then attacked by two Sabretooth Tiger to whom he swatted them away quite easily without even using much strength. Suddenly, he was attack from 5 directions and saw that it was those wolves who intervened in his fight against the Sabretooth Tiger. He thought 'Let's take care of you all first. Let's show you why Shisui was known as one of the Fastest Ninja.' He knew about wolves, he knew that they were very weak individually one on one but were very strong in a pack. He put down his Susanoo as he knew that it would be of no use against the Wolves who had speed as their advantage.
He then started using the Shunshin and it was so fast that it created many afterimages of Ryusuke all over the place. He hit all the Wolves at the same time and knocked them out, Ryusuke then used three of his After images to attack a Sabretooth Tiger from three different directions. After some time even, the physique of Sabretooth Tiger wasn't able to insist any longer died due to being beaten mercilessly by Ryusuke.
The other Sabretooth Tiger looked towards its friends and howled in a loud voice and soon more and more beasts came to their place. This time a Rhino, 3 foxes and a Lion came. Ryusuke suddenly sensed someone attacking and made the Frozen Cloud Wall which created a wall between him and the fox and saved himself from its sneak attack.
He knew he couldn't relax himself and made three more afterimages and similarly beat the Sabretooth Tiger to its death. But while his afterimages were beating the Sabretooth Tiger, he was dodging the attacks of Lion, the Rush Attack of the Rhino and the sneak attacks from the Foxes. Ryusuke knew that if he got distracted for even a single second, there wouldn't be much of his corpse left after these Beast were done with him.
Suddenly, he felt the Sabretooth Tiger was dead and used his Susanoo and caught Rhino's head in the Susanoo's hand. He then applied a bit of force and was surprised as he found that its head was really hard. Ryusuke threw the Rhino on the ground and punched its head, its head was crushed under such a strong punch from the Susanoo.
Even the Beasts backed away when they saw such a grewsome scene in front of them, especially the Foxes, they were thinking of running away and suddenly, Ryusuke deactivated his Susanoo and condensed a sharp Ice Shard in his hands and cut apart all three of the Foxes in a blink of an Eye. Ryusuke then turned towards the Lion and smiled, but Lion shuddered as it backed away when he saw this smiled.
