Here is more of chapter 10
Ron finally arrived at the bathroom, five minute later. They frantically began reading the book, for any other clues on Horcruxes, besides the ones that they already had, they found out that a wizard that usually makes a horcrux, will not only put it in a place that he is familiar with, but he will set up barriers to protect it, barriers that only a powerful wizard would be able to get through, one that would be able to hear in their mind what the barrier was asking for. Harry then thought of when he and Dumbledore went to the cave, and he remembered Dumbledore leaning toward the wall, and then like he knew exactly what the wall was asking for, he cut his arm and dropped blood on it.
This means, that we must learn to control our magic better, as to be able to tune into magical noises that only powerful wizards can here. Well there is only one person alive that we know can help us learn, I’ll send a letter to him tonight, and ask him if he will teach us.
That night after the DA meeting, at which Harry had pushed everybody so hard, that they had mastered the trio spell, HAHISTNA, HAHISTNA CONTRAIG, and RELEASO HAHISTNA, Harry wrote a letter to Regulus, asking him if he could teach them how to fine tune their magical senses.

Draco woke up that morning ready for anything, his lessons with Snape had been exhausting, and on the days when Snape said it would be a long day, it nearly killed him. Snape had not told him what was going to happen, he had not told him that the Dark Lord was coming to check on them, he had not told him that he had volunteered to get him ready for this task.
“Draco, come here there is somebody here that wants to see you.” Snape said
Draco hurried into the room, looked around and was surprised so see the Dark Lord there. When he realized he was there, he hurried over bowed down, and kissed the hem of his robes. He then stood up and waited for his master to speak.
“Draco, I hear that you are doing much better in the lessons that Snape here has been giving you. I am correct to say that?” Voldemort said.
“That is what Snape tells me as well, so I would say you are correct.” Draco replied
“Would you mind if I got to see what he taught you for myself?” Voldemort asked.
“No master, but you should know he hasn’t yet prepared me much to attack yet, only to defend, he tells me that Regulus was one of your best Death Eaters when it came to attacking.” Draco said
“He would be correct to tell you that, but nonetheless, I would still like to see how you fair in a little duel.” Voldemort said, “No Draco, you will not be fighting me, but you will be fighting one of my death eaters. Nobody will die in this duel; I just want to see if the student has surpassed the teacher yet.”
“Me?” Snape asked, “You didn’t tell me that I was going to be dueling him, if I had known that I would have rested better, I was convinced he was going to be dueling you.”
“That is what you get for your ignorance Severus. You will duel the boy, or you will duel me.” Voldemort said. “Now that all of that is settled, wands at the ready, now bow, and begin.”
“ROHASHITO” Snape bellowed
“HAHISTNA” Draco replied, and the tiny little magical mirror appeared in front of Draco, and reflected the spell back towards Snape.
“HAHISTNA CONTRAIG.” Snape responded, and the magical mirrors appeared in front of him and absorbed the spell, he then placed the mirror into his pocket.
“CRUCIO” Draco said, and it hit Snape square in the chest as he was placing the mirror in his pocket. Snape fell to the ground and started screaming from pain.
After a few seconds, he got up and angry he yelled “SECTEMSEMPRA,” but Draco was ready for this.
“HAHISTNA” he called, but that is exactly what Snape was waiting for, Snape quickly pulled the mirror out of his pocket, and held it up in front of him, and the mirror absorbed the spell, but to his surprise, the mirror did not start glowing, it was not powerful enough yet he thought.
“FURNUNCULUS” Draco called.
Snape wondered why Draco would use such a weak spell, but still screamed “HAHISTNA” then he realized what he had done, Draco had the same plan that he did.
“HAHISTNA CONTRAIG,” Draco bellowed, and a proud smirk came on his face. He was getting close to being able to defeat Snape.
“CRUCIO” Snape said.
“PROTEGO” Draco responded, and the spell was blocked.
The Dark Lord watched all this, and was pleased with how much defense that Snape had taught Draco. He noticed that not once has Draco been hit by a spell, and Snape had been hit once. Then he realized “Severus, do your best, or I will kill you.” The Dark Lord said.
