With a "bang", Hanzo opened the cell and stepped forward to confirm the prisoner's condition.

"Still dead!" Hanzo sighed in his heart.

Ever since Orochimaru had completed the spell mark technique, he had begun to plant spell marks on the detainees to see if there were any adverse reactions. It's just that the curse mark is inherently dangerous, and most of the people who receive the spell mark don't survive the initial adaptation period.

So when there was no research project, Hanzo went back to his old job, pulling out dead prisoners and burying them every day.

For Orochimaru, having Junmaro bribe the daimyo of Tanokuni for more test subjects played a big role.

At first, Orochimaru didn't expect that receiving the curse mark would have such a high mortality rate, so that many people who were caught before died. For a while, he wondered if there was something wrong with the potion he was studying, but he was relieved until the first person who had successfully received the spell mark appeared.

It took a period of improvement to reduce the mortality rate. But even if this is done to the point where there is no way to change it, the mortality rate is still 90%, and only about one in ten people can succeed, plus the requirement that the physical fitness of the test subject itself is at a certain level.

Carrying the deceased out of the base Hanzo to the place where the body was buried. The burial site was also carefully chosen by Hanzo, neither too far away to be discovered that the land had been renovated, nor too close to affect the environment.

Covering the soil little by little, Hanzo silently muttered in his heart: "There is a debtor and a master, these are the pots of the Great Snake Pill, and they have nothing to do with me." "Even though he knew it was a catharsis. After all, there are no less than 100 corpses buried in Hanzo, and because of the simple burial, there is no way to know whether the foot is a burial site.

After finishing his work, Hanzo went back immediately, without delay. No way, due to the spell seal, Hanzo must improve faster.

"Hanzo, I'm back." Jun Malu, who was about to go out to cultivate, happened to run into Hanzo, so he said hello.

"Well, you're going out to cultivate?"

"Yes, Orochimaru-sama was busy with experiments and didn't have time to teach us, so I had to seize the time and practice my own."

"Well, that's right. It's a pity that I'm going to recover quickly, and I don't know when I'm going to get back to work, and I'm afraid it won't be long before you catch up with me. ”

"Why!" Jun Maro smiled rarely, perhaps what he valued in his eyes was not the improvement of strength, but the effect that the improvement could bring to Orochimaru more help, and he was very happy to hear Hanzo's praise.

If Hanzo knew what he was thinking, Hanzo would have said that you were thinking too much. Although Jun Malu's blood inheritance limit similar to bone hyperplasia is difficult to deal with, even if it is a shinobi who rashly uses the physical technique without knowing the details, he will suffer a big loss.

But Hanzo is different, knowing that melee combat won't work, he never thought that if he fought against Kimimaro one day, he would use hand-to-hand combat, and would only use long-range attacks. If the long-range attack can't be done, then "the enemy advances and I retreat, the enemy is stationed and I disturb, the enemy is tired and I fight, and the enemy retreats and I advance", relying on his advantage of chakra higher than his own chakra to deeply drag him down.

Suddenly the labor pain hit, Hanzo's muscles tightened, gritted his teeth and endured the pain, Hanzo didn't care about communicating with Junmaro, leaned against the wall to relieve the pain.

Seeing that Hanzo's face turned pale, Jun Malu probably knew something, and stepped forward and said with Hanzo, "Haven't you fully adapted to the curse seal?" ”

"Hmmm! However, the frequency is not as frequent as it was at the beginning, but it will come again occasionally, and it will probably take some time. Hanzo said with a reluctant smile.

On that day, Orochimaru planted two batches of curse marks on two batches of experimental subjects in a row, all of them died, and when he was in a bad mood, Hanzo who was standing next to him put forward the conjecture that "maybe a person's physical fitness will also affect the success rate", so that Orochimaru, who was gradually going crazy, directly used the spell mark technique on Hanzo, regardless of whether Hanzo would die or not.

When Orochimaru's snake kiss flew towards Hanzo, Hanzo, who was expecting the power of the curse mark, suddenly realized that there was a risk in receiving the curse mark, and he missed two lines of poetry at that time, ah no, when he wanted to say things like "I have made meritorious contributions to adults, I have shed blood for adults".

It's a pity that Hanzo was speechless in pain before he could speak in a hurry, and he fell to the ground and convulsed continuously.

Perhaps because of the aura of the traverser, Hanzo succeeded in obtaining the spell seal without accident. Although this was inconsistent with Hanzo's own vision, Hanzo wanted to wait until he was fully prepared to get the spell seal, but he was suddenly attacked.

"I'll help you go back first!" I don't know how long Hanzo will be like this, so Jun Maro said.

"Well, thank you, Kimimaro."

"You're welcome."

Slowly returning to the dormitory with Hanzo, saying goodbye to Hanzo Hanzo, Junmaro closed the door and left.

Lying on the bed, Hanzo was already much better, and thought to himself, "If it weren't for Jun Mario's single-mindedness as Orochimaru, if he was born in Konoha, maybe the two of them would still be friends." ”

At this time, Jun Maro had not yet received the curse mark, although Jun Maro went out that day to bring some new test subjects back and did not go with Hanzo, but after coming back, Orochimaru did not plant a spell mark for him.

In Hanzo's opinion, this may be because Orochimaru wants to use him as a means of restraint, and Junmaro doesn't need it because he is willing to serve Orochimaru. Of course, whether this is true or not, Hanzo doesn't know.

After a long time, the recovered Hanzo separated into a shadow clone, and looked at some scrolls of the sealing technique with the main body.

Receiving the mantra seal this time did have some benefits for Hanzo. The most intuitive is the improvement of strength, originally Hanzo's strength has been at the middle level of the ninja, and now the activation of the spell mark is close to the level of the upper ninja in terms of the amount of chakra, of course, the quality and other aspects are incomparable.

In addition, due to the curse seal, Hanzo asked to learn the sealing technique on the grounds of affecting the state, and after learning it, he sealed it.

Although Orochimaru saw Hanzo's thoughts, he still gave Hanzo the scroll related to the sealing technique, probably as a kind of transaction.

When the time was almost up, and there was nothing wrong with his body, he put away the scroll and went to the laboratory to see if there was anything he could do to help.

During this time, since Orochimaru developed the spell seal, he found that there was still no way to do it like the immortal magic described in the Dragon Cave, so he ended this research project and turned to something else.

Due to Hanzo's health, Orochimaru let him participate in new research when he was better.

In Hanzo's opinion, Orochimaru's mentality at this time is becoming more and more like what it was after, and studying ninjutsu is no longer for strength, just for studying ninjutsu.

"Knock knock!"

Seeing that Orochimaru was not touching the bottles and cans, Hanzo knocked on the door to signal.

"Come in, Hanzo."
