Fujin quickly ducked down to avoid a kick and moved back to avoid Guy's fist. However, Guy followed up with a kick straight towards Fujin's face. Fujin cursed, 'Shit, I can't dodge fast enough!'

He quickly jumped backwards to soften the impact of the blow. At the same time, he raised his arms to block the kick. Before Guy's kick landed, he instinctively used the Iron Skin jutsu to harden his arms.

Guy's kick landed on Fujin's arms. Immediately, shock appeared on Fujin's face as he felt the power behind the kick. Fujin had sparred with Guy on a regular basis for the past few months. He had to endure several kicks and punches. Though Guy's body was stronger and his attacks were heavier, Fujin could always endure the hits.

However, this time, Fujin was launched backwards like a cannonball. The Iron Skin jutsu covered his entire body. He smashed through two trees which slowed him enough to flip in the air and land on his legs and knees.

However, he was still dragged along the ground for around 25 meters and only stopped after hitting the third tree. Despite protecting his arms with Iron Skin jutsu, Fujin could still feel them aching. Fortunately, the rest of his body was fine.

He thought in amazement, 'Just the First Gate provides so much buff? So this is the result of using your body at 100% and removing all mental inhibitions? His speed was fast. More importantly, his movement was just too fluid. Is this due to the improvement in Muscle Movement that he said? And his kick was so heavy as well!'

Guy looked at Fujin's expression and said, "By removing the mental inhibitions, your brain no longer limits the extent of physical energy you can use. It also removes any sense of holding back due to the fear of hurting my body due to my power. Hence, I can use all my strength.

Though the effects aren't very obvious to the eye, you should have felt them. Apart from my increase in chakra, the improvement in my muscle movement allows me to move and more importantly react faster.

You could dodge my first attack, but the successive attacks became harder for you to dodge because your body couldn't react as fast as mine. And since I no longer cared about hurting myself, my strength was far greater than yours."

Fujin thought for a bit and nodded. He said, "Yeah, dodging your first kick wasn't difficult. But it became very difficult to dodge the follow-up attacks. Your kick was far heavier as well. I can still feel it."

As he talked a smile appeared on Fujin's face. He thought, 'Not bad at all. Though I have already seen it, I wasn't expecting such a surprise from the First Gate. In the show, only the last 3 Gates were useful when combating against rank S ninjas. So, I didn't have much hope from earlier Gates other than the Gate of Healing.

Once I am done with the Flying Thunder God and the seals I want to create, I can focus on the Eight Inner Gates along with my Wind Domain and keep that up at least until I can learn Senjutsu. No matter how many Gates I can open, it'll just be beneficial for me as long as I don't use them repeatedly.'

He looked at Guy and asked the question he wanted to ask for a long time, "How do I open the Gate of Opening?"

Guy said, "You will first have to locate the chakra point in the Left Hemisphere of your brain."

Guy took out a few scrolls from his jacket and went through them until he found the scroll he wanted. He opened it, showed it to Fujin and said, "Study this diagram properly and observe the location of that chakra point in the diagram. Every individual has their chakra points at slightly different positions, but they are still close by. Try to find your chakra point that acts as the first Gate. If you want, you can read the notes as well."

Fujin nodded and said, "Thanks, Guy."

Fujin carefully went through the scroll. After understanding everything, he closed his eyes and sat in a meditative position. Chakra began flowing smoothly throughout his body. He focused on just the chakra points in the left hemisphere of his brain. In a couple of minutes, he located the chakra point that Guy and the scroll were referring to.

He opened his eyes and said, "Found it."

Guy said, "Good."

He took back the scroll. Fujin couldn't help but ask, "Do you carry such scrolls all the time with you?"

Guy chuckled and said, "Just a few. They don't have details on all the Gates. I also use it to make notes in case I discover something new while training or opening the Inner Gates during a fight. Besides, most of the villages already have the method of learning this technique. They just lack anyone who would be willing to train all the time."

Fujin thought, 'Hmm, that makes sense. Even in Konoha, there are the likes of Hiruzen, Danzo, the three Sannins and Kakashi. None of them lacked talent. However, none of them are willing to train all the time like Guy did. Of course, considering their talent, it could be just because they don't need it.

After all, not everyone can be like Guy who almost killed Madara who had reached the level of the Sage of Six Paths. By comparison, Might Duy, who opened the Gate of Death, was only able to kill four out of the Seven Ninja Swordsmen of the Mist.

Madara, even when he only had the Eternal Mangekyou Sharingan could still kill all Seven Ninja Swordsmen of the Mist without breaking a sweat. Heck, even Hiruzen might be able to do it, assuming someone like Kisame isn't a part of that team. So I guess they didn't value it that highly considering the costs.'

Still, Fujin was surprised. He chuckled and said, "I never thought of you as someone who would make notes, Guy."

The image of Might Guy sitting and writing notes was just too funny for Fujin to imagine. Guy laughed as well and said, "Well, it can't be helped. No matter who, if you want to become strong, you can't ignore such basics. Anyways, now that you have found the chakra point, focus your chakra on it. You will feel some resistance. If you don't, then it would mean that the chakra point you chose is wrong and stop immediately.

Once you feel the resistance, force as much chakra as you can through it. Since it is your first time, it will be difficult. But your body is sufficiently strong. You should be able to do it relatively easily. In the best case, you might get it done in a few minutes. In the worst-case scenario, you'll open it in a week."

Fujin was surprised. He wondered, 'That fast? Hmm, now that I think about it, it makes sense. After all, Lee would master up to the 5th Gate in less than two years. And his body now is far weaker than mine when I graduated. Well, let's hope everything goes well.'

Fujin closed his eyes and focused on that Chakra Point once again. He tried to gently push a little amount of chakra through it. At the start, some chakra went through the Chakra Point. But very quickly, it resisted. Fujin couldn't push any chakra through it.

He thought, 'It looks like I spotted it correctly. Alright, here goes nothing!'
