"My friend! I am back and I need some of those woods ASAP! Chop chop!"
Appearing inside Divine Tree, Yoichi glanced at the juvenile Ten-Tails.
"ROAR!!!" Sensing the familiar nemesis, Ten-Tails roared in grief and anger.
The roots quickly subdued his body, familiar with the dangers this human imposed against him in their last encounter.
All of the energy including his Ki was being slowly siphoned with his body immobilized.
Although its devouring power was not lethal and almost negligible, the humans of this land are fragile beings and not nutritious due to its sucking power of natural energy as this energy cultivates crops and other resources needed by humans. They still don't have the Inheritor of Chakra and if the Divine Tree wanted to grow up faster, the tree needed a massive quantity of sacrificial humans.
"Oh! This is your remarkable gift?! How sweet of you! I will also get just a little bit of Chakra Fruit. Surely, you don't mind, right?" Yoichi vanished once more with the roots broken in their source.
"Universal Swap!"
"ROOOAAARRRR!!!" Ten-Tails felt excruciating pain.
Back at the tree's summit, Yoichi chopped half of Chakra Fruit and stored both his loots in the sample container.
'Wow, the big strawberry became a medium strawberry! Uh-oh! The tree is getting small!'
Yoichi inspected the peculiar scene. The Chakra Fruit recovered but the size of it became too small. In his first encounter, the Chakra Fruit was the size of an industrial-grade water container but looking at the fruit now, it's in the wrecking ball size.
Otsutsuki Clan propagated the seedlings of Divine Tree for one purpose: to gain biological information about this world by sucking surrounding energy and cultivating Chakra Fruit to be eaten by a Higher-Ranked Otsutsuki Clan Member.
Of course, for power. Cosmic civilizations always find some ways regardless of how ruthless and unethical that would be.
"OMG, I am tearing up! I am very grateful for this wonderful gift. I will pay for this favor in the future! Bye." Yoichi shamelessly ripped the Divine Tree up as he vanished once again.
"ROAAAAAARRR!!!"
Sensing the intruder was gone, Ten-Tails growled in indignation. The [Extraordinary Barrier] was still there and nobody heard his grief and despair.
Yoichi came in an instant like a thug and ripped some of its materials like a fruit tree in his garden, plucking the fruit wantonly.
Furthermore, the tree has self-awareness but he can't do anything about Yoichi's thuggish conduct and his powers. It's like child abuse at this point. Daylight robbery.

Around 8 AM.
"Sensei! You're back!"
Ryoma greeted his sensei while the other two were still focused on the books, looking particularly fine and grounded in studying.
"What's up? Any questions?" Yoichi ruffled his hair, looking at the exhausted figure on the Training Ground.
"I can't slice this straw dummy and I've tried several times but this little dummy seemed to be so sturdy! Any tips on swordsmanship, Sensei?" Ryoma grumbled and scratched his head.
Looking at the training dummies in the training ground, Yoichi noticed that the dummies were spotlessly clean except for the small one that was roughly the size of Ryoma. The small dummy was battered with broken parts, especially on the left shoulder as if the intent was to cut the dummy in a diagonal direction.
"Nice job, you know how to pick your suitable opponents." Yoichi praised his remarkable clarity of judgment.
"Hehehe, this dummy looked like one of the bullies I fought against so I went ahead and ruthlessly beat this dummy!" Ryoma's cheeky grin earned Yoichi's chuckles.
'This brat is so upright and vengeful! Another trouble magnet in the future.'
"Let me look at how you slice this dummy first," Yoichi shrugged his shoulders and patiently instructed him.
"Yes, sensei!" Ryoma grabbed his uchigatana and went to his stance.
"HAAAA!" Striking at his opponent, Ryoma's uchigatana stopped at the dummy's trapezius muscle.
"From what I've seen, you are using too much brute strength in slashing! Don't waste your energy on your arms, use all of the compound muscles needed for slashing. Be sure to implant your foot firmly and then twist your body a little bit so all the energy in the muscles will work and deliver a much more lethal slash!" Yoichi explained to Ryoma who was puzzled in his sensei's explanation.
"Here! I will show you!" Yoichi grabbed one of the training swords nearby and went into his stance against a big dummy in front of him.
"If you intend to slash in his left shoulder, implant your right foot here. All of the muscles including the legs must be firmly contracted."
"Then as you slash, twist your upper body. You can't do a little twist since it will only generate a little force. As a kid like you, you can do many more forceful twists because you don't know the exact twist of the body."
"When you have adapted and had the mastery, you will notice the difference and adjust to the twist depending on your choice." Yoichi carefully demonstrated the positions and proper muscle control as Ryoma mimicked the same movement.
"After that, grip your hilt tightly. Your dominant hand must go to the upper hilt as your other hand will support at the lower hilt. Extend your wrist so the force will be much more powerful. Here's the complete demonstration!" Yoichi slashed the dummy in the right shoulder.
The dummy was sliced in a diagonal direction, leaving his dummy's right part dropped into the ground.
"Then how did you slice your opponent in that direction?" Ryoma curiously asked his sensei.
"It's called proper sword aligning, I've also noticed that you are gaining habits of practicing warrior. Maybe you've seen them cutting countless times. Although I can't say that was a bad attempt to practice, they are strong and experienced warriors. As for you, your body is still fragile. These warriors have the experience of knowing which are the weak points even if their opponents have plate armor or not. Work on the fundamentals first." Yoichi sternly stared at Ryoma. He guessed it right away.
Of course, as a kid wanting to learn how to fight. Their first stop was the adult warriors practicing cutting in the wide-open field.
As for the teaching part, these warriors have egos and are in their proud state. As they said "These are adult matters, don't bother even learning such stuff. Just play with those kids on the grasses."
Furthermore, the dojos nearby were costly for civilian families. Just copying the adult warriors slicing for endless times must be sufficient in their minds.
Such classic narrow-minded thoughts were prevalent in this era. Upcoming warriors must be bathed in blood just to feel and adapt due to the lack of teaching.
"As for teaching you how to proper sword alignment, go get some of the fruits near the vicinity. Cut those fruits and review the fruit you've sliced."
"Did you use too much force when you cut the watermelon? Properly adjusting the sword must be the problem."
"The sword didn't cut through? Maybe the emphasis on the body was insufficient."
"Those are the things you need to pay attention to. Do not worry about the time and just practice. There's a lot of time here!"
"Practical and theoretical practice must be in sync for your future growth and potential." Yoichi summarized all of his teaching on Ryoma who was patiently listening to his valuable ramblings.
Talent was a component but hard work and research are also key factors for a better understanding and comprehension.
"Go on." Yoichi left the training ground.
Ryoma was excited about his newfound lessons and mistakes. He understood some of it but as Yoichi said earlier.
"There is still time, just practice!"
———————————————————
'That kid was a diamond in the rough! Further polish and experience. It will shine in the future.' Yoichi thought as he arrived at his experimental lab.
[Biological Sample - Divine Tree Roots.]
[Biological Sample - Chakra Fruit.]
Both of his loot got registered in the lab, which means that these two genetic samples will be infinitely generated by the lab. No such thing as few materials here.
'But first, let me look at the unique energy of this world called "Chakra". Based on my information, Chakra was inside all of the living beings ever since they were born inside of this world. But in this era, people get ass blasted every single time. They don't have the proper information about how to utilize and operate such energy in their bodies. As such, I'm gonna focus on refining Chakra since I am not from this world and my rebirths are still there.'
"Oh... I got it on the first try!" Yoichi sat down and focused on drawing his Chakra.
A mix of spiritual energy and physical energy slowly revolved inside his tenketsu (Chakra Pathways) as Yoichi began to inspect this extraordinary energy filling his entire body.
