After taking over the snake uncle's foundation, Sasuke came to surrender on his own initiative.

With nothing to do, Yinzhu, under the guidance of Akita, a civilian ninja from Totaki Village, went deep into the village located deep in the waterfall.

According to this newly recruited subordinate, inside the waterfall, the Puxiang and major family lands that have been passed down for hundreds of years in the Land of the Dragons are interconnected, almost as one, and they have jointly built a hidden treasure house.

Now, Yin Zhu finally became interested.

"After all, it is a medium-sized ninja village with nearly 2,000 ninjas and tailed beasts. The ninja clans that monopolize more than 90% of Takigakure's wealth must have accumulated a lot of treasures over the years... Well... We still have to call Neji over first."

After some further searching, the three finally found a mysterious treasure house with flying eaves and brackets behind an underground passage.

Even though any of the ninjutsu secrets collected in the treasure house here could not catch Yin Zhu's eye, and even did not arouse his interest at all, Yin Zhu still looked energetic.

Because when stepping into this treasure house, in the sight of the Mangekyō Sharingan, the chakra here is nearly half as dense as that in the outside world!

"Is there some kind of barrier that speeds up cultivation?" Yin Zhu's eyes flashed with surprise, and he immediately made a bold guess. "Why didn't I find this type of barrier when I read the original? Or... is it the ninja world's version of a spirit gathering array?"

Being here, he felt a vague sense of inner peace, as if his eyes and ears had become sharper, and as if the surrounding architectural pattern had undergone a drastic change in an instant, transforming from a bustling and noisy village to a quiet and remote valley in an instant.

He immediately realized that there might be some good things hidden inside this treasure house.

Following Ototake's command, Neji began to search carefully with his Byakugan.

As expected, the three found some fist-sized pieces of chakra metal in the foundations of many corners of the treasure house.

According to the analysis of Naruto fans in previous lives, these metals may be special minerals formed by the abnormal power generated when the ancestor of Chakra came to the Ninja World. They have the characteristics of high conductivity and hardness of Chakra.

Because these metals are often found deep underground in rivers, lakes, and mountains.

Usually only the deep heritage of the big ninja villages can possess it.

Some other smaller ninja villages or organizations' bases occasionally have very small stocks.

It is precisely due to the magical effects brought by minerals such as Chakra gold metal.

Therefore, since the Warring States Period, when establishing their family clans, most ninja forces in the ninja world would choose to bury this precious chakra metal in certain special-purpose buildings, and then expand its effectiveness through special barrier techniques.

Over time, the environment inside the building will undergo miraculous changes, creating a unique environment that is beneficial to the human body, increasing the chakra content in the air of the family's land, and slightly speeding up the cultivation speed of the clan members.

These secrets are only circulated among a very small number of ninjas in the ninja world and passed down from generation to generation.

Although it was not a core secret, given Yin Zhu's status and position in Konoha, it was impossible for him to know it.

The amount of chakra metal found in the treasure house of Takinin Village is not small, with a total of seven palm-sized pieces of chakra metal.

Yin Zhu dug them all out without hesitation and packed them up and took them away.

Immediately, he began to search again among the collection of esoteric arts in the treasury, and finally found an ancient barrier technique called "Chakra Array".

The effect of this barrier was exactly as he had imagined.

It is to transform the caster's chakra into special properties, and then create a barrier space filled with chakra metal ore, so that the chakra content in this space will gradually increase.

Seeing this, Yin Zhu nodded repeatedly.

"Not bad, not bad. Although most ninjas are limited by their talents and the total amount of chakra they can cultivate is very limited, this thing is really useful. It is suitable for cultivating power and is also very suitable for people who have just started to cultivate chakra..."

"Spiritual Calling Technique!"

While storing the wrinkled gray scroll in the storage scroll, Yin Zhu touched his chin and smiled mischievously. "In that case, let's leave the task of building the chakra barrier inside the Oto Village to Karin."

When it comes to sealing techniques, Karin's talent is unmatched in the entire Sound Village, and sealing techniques and barrier techniques are interconnected.

Besides.

This treasure house hidden deep in the waterfall may not contain any high-level ninjutsu or secret techniques.

However, in terms of their value, these seven pieces of chakra metal are undoubtedly superior to those so-called inherited ninjutsu and secret techniques.

When they left the treasure house, they immediately asked Kimimaro to lead his team to plunder other treasures in the treasure house. After all, the capacity of Yinzhu's storage scroll was not that large.

The Sound Ninjas shouted and screamed, and collected a lot of gold and boxes of paper cash, totaling more than 6 million taels, which was almost equivalent to the heads of Asuma Sarutobi.

In addition, there are thousands of standard ninja tools of various types, such as ninja swords, shurikens, kunai, detonating tags, and thousands of poison needle smoke bombs, etc.

Regarding these spoils, Yin Zhu directly ordered his Yin Ninjas to pack them into boxes and bring them back to the village for distribution.

This was the first time that Yinzhu experienced the feeling of getting rich through war.

Not only are there a lot of experience points, but there is also a huge harvest of money and supplies, which is enough to greatly speed up the expansion of Sound Village.

"After a short rest, we will return to the Otogakure. At the same time, we will also give out some of the low-level ninjutsu that has been squeezed in the system warehouse for a long time as rewards to improve the enthusiasm and sense of belonging of the Otogakure... As for the personnel and expansion of the village, we will leave it to Zabuza and Kabuto to handle. These seven or eight hundred Takigakure will all be brought back to the village, and then some of the more loyal Otogakure will be transferred to guard the Takigakure Village. Then... there is only one last thing left to deal with..."

Walking out of the treasure house, Yin Zhu pondered in his heart.

This matter is the most important part of his plan to destroy Taki Ninja.
