Start farming in Konoha

Xu Qiang looked at Cheng Shui's staring eyes and said helplessly, "Okay, the teacher won't tell you, but there is still one month until the exam, so you should work hard to strengthen your strength."

Cheng Shui nodded with satisfaction after hearing what Xu Qiang said and said, "We must also work hard to improve and strive to become a chunin before Hiruzen and the others, and I will definitely defeat him this time."

You haven't won at all, Xu Qiang secretly complained. Because they were both in Konoha Village, Cheng Shui often competed with Hiruzen and the others. As far as Xu Qiang knew, Cheng Shui and the others had not won once. Here, Among the batch of ninjas, only the three-person team of Uchiha Madara's students, Senju Seiye, Hyuga Hoshisai and Kato Taka can compare with Hiruzen and the others. If Cheng Shui and the others really meet Hiruzen, they will definitely lose. Such a result is unacceptable to Xu Qiang. After all, this is his first time leading students, and he cannot be worse than Hashirama and the others.

So when Cheng Shui and the others were working hard to develop their strength, Xu Qiang also thought of ways to improve their strength. Xu Qiang remembered that in the anime, Tsunade had a Yin seal. This sealing technique is to store chakra on the forehead. This large amount of chakra can stimulate various proteins and rapidly accelerate the number of cell divisions, thereby allowing cells to rebuild and regenerate all organs and tissues. It’s not resilience, it’s regeneration. In other words, you cannot die in battle. However, since cells divide only a limited number of times in a person's life, lifespan will be shortened after use.

However, Xu Qiang does not need such a powerful ability. He only needs to be able to store the chakra of Orange Water and others. This is equivalent to having an extra dantian. After all, the chakra in this world is really a scam, even the chunin-level chakra. Can't release a few ninjutsu. And with this Yin seal, Cheng Shui and the others at least don't have to worry about insufficient chakra. You must know that in this world, ninjutsu is combat power.

After having an idea, Xu Qiang just went ahead and found the place where Ninjutsu is stored in Konoha Village. This place is still open to high-level people like him, but it is all ordinary Ninjutsu. Of course, this is what Xu Qiang wants.

Xu Qiang searched here and finally found a scroll recording sealing techniques. Here are the most basic four-image seals and five-element seals. Xu Qiang recorded them all, and then returned to his home to start learning.

After arriving at home, Xu Qiang entered the system space. After all, the sealing technique is completely different from what Xu Qiang usually learns. If he was given a few years, he might still be able to learn it, but now less than a month is definitely not enough, but Fortunately, he had the krypton gold system, and he still had enough money to spend it. Xu Qiang looked at the system where the funds showed 150 million gold, which should be enough to raise the seal to the highest level. Sure enough, having money makes a difference.

Then he said, "How much does it cost for the system to learn elementary sealing techniques?"

"20 gold"

Xu Qiang heard that since learning the sealing technique is more expensive than becoming a genin, the price of goods has increased. "Systematic learning."

After a while, a lot of knowledge about sealing techniques appeared in Xu Qiang's mind, but they were all elementary after all.

"The system will continue to upgrade the sealing technique," Xu Qiang said.

After spending 200 gold, he had some more knowledge about sealing techniques in his mind, and this time he upgraded to intermediate sealing techniques.

"The system will continue to be upgraded"

After spending 2000 gold, his sealing technique reached an advanced level.

"System Upgrade"

After consuming 2 kilograms, he saw that the system showed that his sealing technique was expert level. But there is still no knowledge about the Yin Seal.

So he gritted his teeth and said, "The system is being upgraded."

After spending 20 yuan, his sealing technique reached the master level, but he still had no knowledge about the Yin Seal. Now it was impossible for him to upgrade it. After all, he would not be able to afford the 200 million gold later.

"How is it possible? I'm already at the Grandmaster level. Why don't I have any knowledge about the Yin Seal? You know, this is the money of 2 Shadow levels. Are you kidding me?"

"The system did not find any information about the Yin Seal"

When Xu Qiang heard the system's answer, he thought that the Yin Seal was invented by Tsunade. She was not born yet, so she had no knowledge of the Yin Seal. However, Xu Qiang was only disappointed for a moment and then thought that he already had a lot of knowledge about seals, so he could just create one if he didn't have it himself.

Xu Qiang began to sort out the requirements for the Yin seal. First, it can absorb the excess chakra of the human body. This is not difficult. After all, many sealing techniques have knowledge about absorbing chakra. After all, the sealing technique of the Uzumaki family is a tailed beast. Chakra can be absorbed, so Xu Qiang can learn from it in this regard, but the most important thing about the Yin seal is to store chakra. After all, the sealing technique cannot store chakra in the Dantian of the human body.

Xu Qiang experimented with this step for a long time, but had no clue. Finally, he got inspiration from the unique ninja sword in the ninja world. After all, in this world, the sword can still run chakra, and it can also increase the power of ninjutsu. Xu Qiang found He took a piece of chakra iron like this and carved a lot of sealing techniques like a processor to seal the chakra. This time Xu Qiang succeeded. He carved 10 sealing techniques on a piece of chakra iron the size of a soybean. The seal that sealed the chakra, and then he input a little chakra, and it went in. However, as long as there is a D-level ninjutsu level chakra, it seems that it still needs to be strengthened. According to Xu Qiang's estimation, it will reach the level of storing jounin level chakra. It would take hundreds of such seals to be carved. Don't even think about it if you don't have thousands of seals at the film level.

No wonder Tsunade's Yin Seal doesn't spread widely in Konoha Village. After all, with this sealing technique, the strength of every ninja in Konoha Village will be greatly improved. Now it seems that people without sealing talent can't learn it at all, and they have to carve it. Not counting time, even those with poor chakra control would not be able to seal so many seals. No wonder the seals were passed on to Sakura alone. After all, in the anime, his chakra control was the best among the 12 Xiaoqiang. However, it is no wonder that this technique has so many requirements and cannot be popularized. After all, those who have learned it can only use it themselves.

After Xu Qiang's own Yin Seal invention was completed, it took him three days to make three of them. Each one was engraved with 3 small seals, which could store a Jōnin-level chakra and could be used as long as it was worn on the body.

After doing this, Xu Qiang came to the place where Chengshui and the others usually trained. Because of the chunin selection, they had practiced very hard during this period, even if Xu Qiang was not here these days. Xu Qiang nodded with satisfaction when he saw this, Children in this world are still very conscious.

When Orange Shui and the others saw Xu Qiang coming, they immediately walked up to Xu Qiang and said, "Teacher, the chunin selection is about to take place, and you disappeared all of a sudden. How can there be a teacher like you? You know, the Hokage gives special privileges to Hiruzen and the others every day." "Training" Cheng Shui immediately complained.
