On the next journey, Yuyi actually began to think about the refining of chakra, but she repeatedly hit a wall because his idea was to convert body energy into spiritual power.

Yu Luo felt that if he didn't stop him for a moment, he could invent the fighting spirit. Maybe at that time, the development of this world was not Naruto, but the fighting spirit.

"Brother Yuyi, your idea may be wrong. After thinking about it for several days, I found that the body energy cannot be converted into pure spiritual power, but I have another idea - that is, to mix body energy and spiritual energy to form new spiritual power."

Yu Luo pretended to be the last time he had this simulation, teaching him how to extract the chakra from the real world.

However, his own body cannot learn. After all, chakra is not extracted by simply mixing physical energy with spiritual energy.

Just like no matter how much humans learn to bark, they cannot smell the subtle smell, because humans do not have the olfactory structure of dogs.

The establishment of Ninja Sect was because the Six Path Immortals distributed chakra to everyone and transformed their bodies. In a more common way, the Six Path Immortals transformed the genes of humans on earth, allowing their cells to produce chakra.

In this way, Yuyi and Yumura quickly learned to refine chakra, but Yuluo, who taught them, still used primitive spiritual power.

Fortunately, Yuyi was a little conscientious and passed the chakra to her elder brother. In a subtle way, the cells were infiltrated and mutated, and Yu Luo would slowly learn the chakra refining technique.

Obviously, the power of using chakra to activate the Yin-Yang technique is much stronger, just like the difference between internal combustion engines burning gasoline and aviation kerosene.

Yu Luo did not continue to teach them seals and ninjutsu, but they all came to simulate the world. It was so boring to take the path of ninjutsu again, and maybe a new system could be found.

When they completed these practices, the disaster relief team had already crossed the scope of the sacred tree and came to the other side of the ancestor country.

"Brother Yu Luo, what is this sacred tree?" Yu Yi looked up at the towering giant tree, and always felt a little intimate.

"Oh, it is the world tree that supports this world. When this planet is still deserted, it is it that sows the seeds of life here, bringing vitality and life to the world."

"It is said that there is a legendary infinite dream under this tree, which is an infinitely beautiful paradise. After the souls of the dead can stay in heaven forever after they return there."

"Ah...Praise the Tree of Mother!"

Yu Luo looked up at the towering tree and was full of admiration. Unfortunately, the fruits on it had been eaten by Kaguya, otherwise he might have tricked two Kotsuki to pick them for him.

"Ah... So it's so great?" Yuyi opened her mouth wide in surprise.

"Yes, but monsters always try to steal the power of the divine tree and eat the roots of the divine tree, which is very distressing... Maybe this drought and famine is where a monster cut off the roots of the world tree..."

"By the way, the guardian of the sacred tree is your mother!" Yu Luo squeezed his eyes.

"Sir Mother!!" Yumura widened his eyes.

"Don't you know?" Yu Luo said strangely.

"I don't know... Mother has never said this to us." Yuyi shook her head.

"That's really sorry... The great Lord Kaguya, I shouldn't be talking nonsense. Maybe she doesn't want you to be responsible so early." Yu Luo looked guilty.

"What does it mean?" The two little ones were stunned.

"Humans are weak, and monsters are powerful, and with the evil ghosts and gods, only Kaguya Hime can't continue to deal with the great monsters. Maybe you will be the next guardian of the divine tree..." Yu Luo's eyes were filled with endless love for Kaguya.

"My mother...is she so great?" The two brothers were stunned.

"Of course, Lord Kaguya is the gentlest person in the world. He always bears the heaviest responsibility alone and never shows weakness." Yu Luo sighed.

"No wonder... My mother often looks at the starry sky alone with sadness..." Hamura felt a little uncomfortable.

"We will definitely become stronger as soon as possible! Let's share the worries of my mother!" Yuyi clenched her fists, full of fighting spirit.

"Brother...the monster...is it really that powerful?" Yumura said hesitantly.

"Yes, not only is it powerful, but it is also very cunning... The more powerful the monster is, the smarter they are. They don't even call themselves monsters, but immortals, to deceive humans."

"The powerful monsters will cut off the roots of the divine tree, plunder the energy of the divine tree, and then transport it to the small universe they opened up, selfishly enjoying the rich natural energy, and also call it the holy land of immortals."

"The human world often suffers from various disasters because of the endless plunder of the immortal holy land. The development of each immortal holy land will be accompanied by the famine that has thousands of miles of the naked land."

"I once met a toad that claimed to be from Miaomu Mountain and said I would teach me immortal arts. If I hadn't accidentally seen a large number of petrified human strong men, I would have almost fooled me."

"Yuyi, next time I see a toad that can talk, don't believe what they say. Just use the Vajra Demon-Suppressing Curse to knock them out. Remember, the ugly the toad, the more lie it, especially the orange toad with pearls hanging on its chest." Yu Luo said as if he was still scared.

"Okay! I will definitely remember to avenge my elder brother!" Yuyi nodded vigorously.

...

After crossing the sacred tree area, the impact of famine gradually became obvious. Hungry people appeared one after another. After seeing the flags of the country of ancestors, they surrounded them and prayed for food.

Looking at the yellow-faced and thin-skinned victims, Yuyi and Yumura couldn't bear it and began to distribute food.

"After this, it's still a month away to reach the core of the drought, and we have nowhere to replenish food, so we have to save a little."

"I suggest that everyone can only receive a rice ball, which is enough to support them to walk to a wealthy village, because there are people who need these foods more behind them." Yu Luo said.

"..." Yuyi thought for a long time before nodding and explaining the situation to the victims.

These first batch of hungry people who walked out of the disaster area were not as hungry as that, and the wealthy village was right in front of them, so they reluctantly accepted this statement and continued to rush forward after receiving a rice ball.

In this way, the warriors drove the donkey cart and continued on their way. They could hardly even see the grass in front of them. Fortunately, with the experience of the last simulation, Yu Luo also prepared a lot of clear water and forage to avoid exhausting the horse, so he had to walk on his legs.

After another half a month and entering the drought-affected area, the disaster will be even worse every day after walking an extra day. Corpse lying on the roadside everywhere, scarlet-eyed wild dogs chew on the shriveled flesh, and the evil energy contained in their bodies will soon turn them into monsters like corpse dogs.

The food carried by the convoy was distributed the day before yesterday, and even a lot of the ponies that accompanied them all the way were killed.

There are thousands of miles of barren land and no grass grows. Even if these horses are not killed, they cannot last long without food. It is better to turn into food.

Buzz!

With a shocking sound, Yucun's long bow trembled slightly, and the feather arrows had shot through the eye sockets of a wild dog. These beasts that were willing to eat corpses would attack humans at any time when they were hungry.

Even the ancestors knew that rolling their eyes should cooperate with long-range attacks. How did it spread to the Hinata clan and become Tai Chi?

"Yuyi, you must be kind to the next journey. No matter how miserable the scene you see, we must keep the last supplies." Yu Luo patted the last box of supplies they left behind.

"Our mission is to find the source of famine and retain enough physical strength to save more people. We must not lose the big picture because of small things. Sometimes painful choices are also a kind of cultivation."

"..." Yuyi was slightly silent.

Yesterday they had two boxes of supplies, but after seeing a hungry family wanting to cook their daughter, he still ordered some of the supplies to be distributed and handed over to the family to get out of the disaster area.

"In the world... as long as there is a holy land of immortals that plunder natural energy exists for a day, the pain will not stop!"

"One day, I will become a great Onmyoji!"

"Expel monsters from the world that are left!"

Yu Luo looked at the desolate horizon, the breeze blew his long hair, and his eyes were filled with infinite firelight reflected by the setting sun.
Chapter completed!
