"Actually, I don't know much about your parents, because we only recently joined Konoha Village, and our original village was destroyed a year ago, and Konoha was our former ally, so we came to Konoha." Zheng Hao was a little depressed, Naruto was really fooled, the essence of this kid is too kind.

Naruto began to comfort Zheng Hao, and after a while, Zheng Hao said, "Today is the first time we have met, as a meeting gift, I will treat you to something delicious!" What's delicious in Konoha Village? When Naruto heard this, he immediately said excitedly, "Of course it's Ichiraku's ramen." With that, Naruto took Zheng Hao into the Ichiraku Noodle Restaurant, and as soon as he entered, he said loudly, "Uncle, two bowls of barbecued pork ramen!" Extra-large portions. ”

"Oh! Naruto! "Uncle Hand seems to have a very good impression of Naruto, too, Naruto is his loyal guest, and the matter of the Nine-Tails attack on the village seems to have nothing to do with him at all. In the memory of Zheng Hao's "previous life", the name of this music can be described as thunderous, after all, Naruto's favorite ramen is Ichiraku.

After eating ramen, Zheng Hao took Naruto home to recognize the door, and in the afternoon, he took Naruto to school again. Now Zheng Hao has to find some ninjutsu as soon as possible, otherwise the identity of this ninja will not be able to pretend sooner or later. At night, Zheng Hao's nanobots began to roam around. Konoha Village is a ninja village, and although most of Konoha's high-level ninjutsu are on the forbidden scroll guarded by the enchantment, Zheng Hao's nanobots can't enter at all. However, Zheng Hao is not unable to get ninjutsu scrolls, and most of the mid-level and low-level ninjutsu scrolls are collected in various ninjutsu families.

After one night, Zheng Hao's harvest was not small, and he got three wind-based ninjutsu, five fire-based ninjutsu, six water-based ninjutsu, and two earth-based ninjutsu. The number of these kinds of ninjutsu is the largest in Konoha Village, although the highest level is only the B-level fire dragon flame bomb, water dragon bullet, and earth-based heart slashing technique, but for Zheng Hao, these are enough, because most of these ninjutsu Zheng Hao can't even simulate, only water ninjutsu and fire ninjutsu can be imitated by manipulating water and fire.

Time passed day by day, Zheng Hao also taught Naruto Uzumaki in addition to practicing and doing tasks, of course, Zheng Hao only taught Naruto some techniques of external and internal strength. Because Naruto Uzumaki has already cultivated the ninja system, Zheng Hao wants to teach him martial arts, but it is impossible at present, but with Zheng Hao's understanding of Chakra energy deepening, he may be able to find a day when Chakra will be upgraded to a true element.

I don't know what these ninjas came up with, Chakra's energy level is equivalent to true qi, and the cultivation of martial artists should gradually improve from internal strength, true qi, and true yuan, and gradually exercise to improve physical fitness while cultivating. And the ninjas of this world refined chakra at the beginning, and in the end, the highest was able to reach the same strength as the martial soul realm.

At the same time as Zheng Hao's research and experiments, the base is also constantly developing, after a year, with the base as the center, a metallic country appeared in the homeland of the country of vortex, the world called this country of steel, because the weapons and armor here are the best in the entire continent.

And in a year's time, first the country of iron, then the country of fire, and finally the five great powers signed an alliance with the country of steel, promising to be the protector of the country of steel, but the condition is that the country of steel can take in wandering ninjas, but cannot accept the traitorous ninja and establish a ninja village, and the ninjas of the five major countries can enter the country at any time to buy what they need. In their eyes, ninjas are equivalent to the strategic reserves of this world, and countries without ninja villages are completely no threat to them.

Tianxuan didn't have a ninja in his hands, and the base didn't rely on the power of the ninja, as for the sovereignty of entering the country, jokes, the world would eventually fall into the hands of Zheng Hao, so it didn't matter at all, what the development of the base needed now was time. As a result, Tianxuan naturally signed this seemingly unfair and unequal treaty without any pressure.

In the underground base of the Steelland Country, the alien brood has been established, and a large number of alien soldiers can be bred at any time, and the reason why it does not reproduce now is mainly to avoid wasting resources. And on the penultimate layer of the underground base, there is Zheng Hao's wormhole and substitute body.

Zheng Hao often returns to the underground base through the wormhole to study this world ninjutsu, not that Zheng Hao wants to use it himself, mainly to teach Naruto Uzumaki, and naturally he must have enough knowledge reserves and ninjutsu attainments, and the energy of chakra is not completely useless, Zheng Hao has a hunch that the next upgrade of the alien will fall on this chakra produced by extracting the essence of life.

In addition to these two floors, there are actually dozens of layers of military facilities and energy facilities underneath the steel country, among which the robot army, the fleet can be said to be on standby at any time, as for those weapons and armor that are too good in the eyes of other countries, they are just toys built by civilian factories on the ground.

After almost a year, Zheng Hao's research also has a little clue, and it is really a blessing to the whirlpool family. Zheng Hao used the sealing technique of the Uzumaki clan to extract a part of the nine-tailed chakra from Naruto Uzumaki, and then sealed it on a dog, but he didn't expect the nine-tailed chakra to directly devour the dog, and finally became another nine-tailed, but this nine-tailed is very weak, and it is not even as good as the middle ninja of this world, but the infinite characteristics of the nine-tailed chakra have been perfectly inherited.

Today, Zheng Hao plans to try to implant this chakra into the alien gene, of course, chakra is naturally not good as energy, but Zheng Hao uses the gene of the little nine-tails and the alien gene to adjust, after hundreds of tests, not long ago finally studied the most perfect genetic adjustment plan.

After the implantation was completed, Zheng Hao looked at the newborn alien egg, and a face-reptile crawled out of the alien egg, Zheng Hao could clearly feel that this face-repellent contained the nine-tailed chakra in its body. Zheng Hao ordered a sheep to be brought, and the face reptile immediately started parasitizing. Half an hour later, the sheep's belly was broken, and a brand-new alien soldier appeared in front of Zheng Hao.

Now, the alien soldier has completely taken on a human form, with arm blades and bone spurs completely gone, replaced by a pair of hands with metallic glint on their fingernails. Of course, this is Zheng Hao's design, and the biggest role of Chakra is to perform ninjutsu, without a pair of hands, how to use ninjutsu. Now, the only thing left to keep the prototype of the alien soldier is the leather like metal chain mail and the mouthparts on his tongue, getting dressed, walking out into the street, wearing a mask, and absolutely no one will think that they are not human, at most they will wonder how this person's fingernails are so long, or the color of their skin is so strange.

However, after the adjustment, Zheng Hao found that he had overlooked a problem, that is, the alien does things by instinct, in addition to being able to attach chakra to his hand to increase the lethality, he will not seal the seal with ninjutsu at all, but Zheng Hao does not dare to increase the IQ of the alien, the combat effectiveness of the alien is so strong, it is because of the alien's killing instinct that is not afraid of death, if the IQ is improved, Zheng Hao does not dare to guarantee that the alien will continue to faithfully carry out the order.

The growth plan of the alien has been completed, and the current alien can reach the peak of true martial arts at the highest level, and the ordinary alien also has the strength of the grandmaster realm. Finally, Zheng Hao orders the newborn alien soldiers to devour the brood and evolve into a new brood.
