As the majestic aura spread, an invisible aura shrouded the gray-clothed old man's body. Those gray mist touched his air shield, and melted in an instant like snow touching the scorching sun.

The other ninjas heard the old man in gray's reminder, and suddenly realized that the gray mist had spread all over the courtyard, and it was impossible to escape to the non-toxic area in the rear before the poison attacked.

Then, the poisonous gas was very stubborn, and the internal strength and internal force of ordinary people could not be eliminated at all. It's just that the black-clothed ninjas who are just acquired combat power can't expel it with all their internal strength, and if they don't hold on for a few breaths, they can't stop the poison and die of poison.

The "Red Belt Ninja" was sweating profusely after a few breaths, and although they did not die of poison, they looked very painful, and they temporarily stopped the spread of the poison, but they were unable to excrete them.

"Hmph, haven't you Chinese people always pretended to be upright, but they were so despicable and insidious, and they actually used poison!" The old man in gray was really angry and annoyed when he saw that his subordinates had suffered a big loss.

"Huaxia pays attention to courtesy, and if the other party treats each other with courtesy, of course we will have corresponding courtesy. And then you island people are using traps, traps, and hidden weapons to the extreme, so why should we put some poison on you?" Inside the passage, Fang Tianyou's mocking voice came.

"That's it, you have so many traps, we rely on two people to break through. Now we're just fighting back, and we're putting a little poison on you, and you're going to fall into a big piece, which can only be blamed for your uselessness. Xiao Wu also said sarcastically.

Of course, it was Fang Tianyou and Xiao Wu who released the poison. The other party's secret weapon made Xiao Wu suffer a little, and Fang Tianyou and the two of them were holding back a breath in their hearts.

Finally waited until the other party's secret weapon was released, Fang Tianyou and Xiao Wu immediately decided to fight back, releasing most of the toxins obtained from the Poison Miasma Valley, and using the light wind charm to release the wind power, blowing these toxins towards the courtyard.

The toxin in the Poison Miasma Valley was the source of the toxin of the Five Poison Sect back then, the toxicity was strange, Fang Tianyou originally wanted to keep it for alchemy and other purposes, but in order to take revenge on the ninja of the island country, he endured the distress and released it.

This release immediately achieved excellent results, the ninjas in black were poisoned one after another, and most of the "red belt ninjas" lost their combat effectiveness.

"Hmph, it's useless, let's see!" The old man in gray heard Fang Tianyou and Xiao Wu's words, and he was even more angry, snorted coldly, and didn't see any vertical leap moves, and his figure had already floated towards the passage.

Xiao Wu has been paying attention to the actions of the old man in gray, and sensing that he has moved, Xiao Wu immediately dodged and stopped in front of the old man in gray, and did not answer, but reached out and smashed it towards the other party with a punch.

When the old man in gray saw Xiao Wu's move, he also pushed it out with one palm, and suddenly a powerful ripple of energy spread in all directions, blowing the flowers and trees in the courtyard to sway violently, and the bamboo house to blow loudly.

As soon as the energy ripples passed, Fang Tianyou took advantage of the time when the two were fighting, and took the opportunity to bypass the battle circle and pounce on the "Red Belt Ninja" who was sitting cross-legged to drive away the poison.

The old man in gray sensed Fang Tianyou's intentions, and hurriedly retreated, and pushed Fang Tianyou with a backhand in the air, preventing Fang Tianyou from approaching the red-banded ninja.

Fang Tianyou was not surprised when he saw the old man in gray making a move, and raised his hand to make a "True Spirit Fist Seal" to meet the palm of the old man in gray, and with the power of the anti-shock of the old man in gray, his figure rushed towards the other end of the courtyard, and instantly entered the passage on the other side.

He originally wanted to take advantage of this strategy to attack the red belt ninja, but in fact, he discussed it with Xiao Wu, and took the opportunity to enter the passage and find Tu Qianqiu as soon as possible.

The old man in gray knew that he had been fooled, and was about to go to catch up with Fang Tianyou, but Xiao Wu had already deceived him, and raised his hand to slam a fist into his chest.

The gray old man saw that Xiao Wu's fist was fierce, and he didn't dare to be careless, and he was even more afraid that Xiao Wu would hurt the red-banded ninja behind him, so he could only dispel the idea of pursuing Fang Tianyou, and calm down to block Xiao Wu's attack.

After Fang Tianyou rushed into the passage, he didn't pay attention to the battle in the courtyard anymore, and walked forward with a quickened pace. The gray-clothed old man in the courtyard is even more powerful than Ishihara Murama, and it is estimated that he should already be a ninja with mid-to-late stage combat power of the grandmaster.

The old guy of Iga Takesha that Fujiwara Chana said should be this old man in gray. Fang Tianyou faced the old man and felt an indescribable pressure.

However, with Xiao Wu's containment, Fang Tianyou didn't have to worry about the gray-clothed old man rushing over, so Fang Tianyou could go to Tu Qianqiu with confidence.

The question now is where Tu Qianqiu is hidden, whether he is just locked up, or whether someone is guarding him. If someone was guarding, the fight outside would definitely have alarmed the guards, would they be unfavorable to Tu Qianqiu because of this? This was what Fang Tianyou was most worried about.

In order to find Tu Qianqiu as soon as possible, Fang Tianyou released his divine sense from time to time to probe. After passing through the courtyard, the passage has been downhill, as if it is going deeper into the ground, and the further down it goes, the hotter it seems to become. Fang Tianyou was really worried about whether he was going to go to the silent magma under Mount Fuji.

After walking two or three miles, Fang Tianyou estimated that he had gone at least three or four hundred meters underground, and suddenly found that the front had actually reached the end. At the end of the passage, like a dead end, there is no way out.

"Could it be that Tu Qianqiu is not at the Iga Martial Arts Shrine at all?" Fang Tianyou couldn't help but be a little puzzled. If Tu Qianqiu is not at Iga Martial Arts, where will he be imprisoned?

In the courtyard just now, these ninjas clearly said that Tu Qianqiu was behind the passage, could it be that they were lying. Even if they were lying, could it be that Fujiwara Chana was lying? It was impossible for her to lie when she was being cast a soul control technique by Xiao Wu.

Fang Tianyou thought about it, but he still felt that Tu Qianqiu was more likely to be here, and he must have overlooked some details. Thinking of this, Fang Tianyou once again released his divine sense and probed the situation of the passage.

He found that the left and right sides of the passage were all soil and stones that he could detect, only the front of Tianyou was only ten or twenty meters old, and then he was blurred, as if something was blocking his detection.

"There are really no three hundred taels of silver here. A hint of joy appeared on Fang Tianyou's face, and he began to look for clues at the cave wall directly in front of him. After a while, he found that there were several very small gaps between the walls of a certain cave, and these gaps combined to form a door.

Fang Tianyou tried to push, but the cave wall did not move. Probed with his divine sense, and found that this cave wall was indeed isolated from the surrounding cave walls, Fang Tianyou increased his strength and operated the True Yuan to promote.

Finally, after he used six or seven layers of strength, the cave wall "boomed" and fell inside, and then a doorway was exposed, and a scorching heat wave rushed to his face, and Fang Tianyou's body felt uncomfortable.

Looking through the doorway, there is a huge underground cave, but this underground cave is extremely special, the temperature is extremely high, if measured with a modern thermometer, it is estimated to be fifty or sixty degrees, which is not something ordinary people can bear.

Perhaps because of the high temperature, there is a lot of heat in it, blowing on people's bodies, making people feel even hotter.

Under the detection of his divine sense, Fang Tianyou was pleasantly surprised to find that there was a person lying in the middle of the cave, judging from his appearance, it was Tu Qianqiu, Fang Tianyou hurriedly dodged into the cave and walked towards Tu Qianqiu.

Just in case, he still runs the true yuan, on the one hand to defuse the heat wave, and on the other hand to be on guard. As soon as he walked in, the door of the cave closed again.

Fang Tianyou didn't bother with the wall gate for the time being, because he was shocked that this place turned out to be a special, similar to the formation of the Spirit Gathering Array, no wonder it could isolate the test of the divine sense.

Walking to Tu Qianqiu's side, Fang Tianyou reached out to probe his snort, and found that his state was not ideal, not only was his internal force chaotic, but he also had many injuries on his body, but fortunately, his life was finally safe.

Fang Tianyou fed him a few mouthfuls of water, fed the second half of the healing medicine, and transported a stream of true yuan into Tu Qianqiu's body. Soon, Tu Qianqiu slowly woke up.

"You ......" Tu Qianqiu looked at Fang Tianyou, his face was a little happy and suspicious, as if he was carefully identifying something.

"Uncle Tu, I'm Godless. Fang Tianyou said.

"God, God forbid. Are you the boss's son Fang Tianyou?" Tu Qianqiu grabbed Fang Tianyou's hand excitedly, but then he seemed to think of the current situation again, and looked at Fang Tianyou worriedly, "Why did you come here, were you arrested by them?"

"No, I'm here to save you!" Fang Tianyou said with a smile.

"Help me, no, you go quickly, you are no match for them, especially since there is an old monster here!" Tu Qianqiu said as he looked at the deepest part of the cave in horror.

Fang Tianyou followed his gaze and looked in, there was a faint red light inside, but because the heat was too thick, he couldn't see the specific situation in the innermost.

Fang Tianyou had no choice but to use his divine sense to probe the past, and found that there was a faint purple light in the innermost part of the cave. In the faint purple light, sat an old man who described the withered manuscript as a dry corpse.

When Fang Tianyou first entered the cave, his divine sense actually detected this old man, but he didn't find his vital signs at that time, thinking that he was really a dried corpse.

Now that Tu Qianqiu's frightened expression reminded him, Fang Tianyou once again used his divine sense to carefully detect this strange old man. Sure enough, I found that although the old man was angry, he did not die, but entered a state of meditation like a Buddhist sitting dry meditation, and it was like practicing a certain exercise and entering a state of dormancy and suspended animation.

"That old monster claimed to have lived for one hundred and fifty years, and he wanted to use the formation here to break the shackles of the Grandmaster realm with the underground flame energy and reach the realm of the unity of heaven and man.

It's a pity that he has been thinking hard here for decades to no avail, so he thought of borrowing from other people's exercises. Therefore, when the people of the Iga Martial Society found out that I was actually practicing a Huaxia exercise that was completely different from theirs, they immediately sent me over. Tu Qianqiu said.
