Lu finally escaped from the Havens territory. If he had continued to stay at that time, I was afraid that he would have made a big mistake. But fortunately, he finally escaped back. But tomorrow, he still has to pick up Ai.

When Ershia comes back, I'm just afraid that Ershia will definitely lose her temper with him.

However, before Lu returned to her room, she saw a familiar person at the door of the room.

"Second brother?"

"You are finally back, brother, I have been waiting for you for a long time."

"Did you say you were waiting for me?"

Caesar nodded and stood up from where he was sitting.

"Brother, I want to become more powerful."

It can be seen from Caesar's eyes that he really wants to become stronger. It seems that in the third preliminaries of the Holy Warrior Festival, he seemed to be very dissatisfied with his battle.

"How strong do you want to be?"

"At least to the extent that it can break mithril."

Mithril is the strongest metal in both the human world and the demon world, and this is recognized in both the demon world and the human world.

"……are you sure?"

"I am sure."

After a period of silence, Lu finally spoke.

"Come with me."

Lu only said three short words, but Caesar heard something from Lu's tone. He felt that Lu probably agreed to his request, but... the training for him was probably

very difficult.

After walking out of the venue, Lu shouted loudly: "Come on, Clan Raft!"

Along with the light hanging from the sky, the bodies of Lu and Caesar were slowly sent into the air by the light hanging from the sky, and then entered the clan raft.

Although Caesar didn't know what Lu had planned, he still followed Lu on the clan raft. After entering the clan raft, Lu gave orders to the clan raft.

"The raft of the clan obeys the order. The next destination is the gravel wasteland."

The command has been received in the operation room of the clan raft, and it has set sail towards its destination - the gravel wasteland.

"Brother, where is the gravel wasteland?"

"It is a wasteland with nothing but stones. There will only be a group of hungry vultures that come to attack humans anytime and anywhere. It is very ferocious, but for you, it is the most suitable place for you to practice."

Hearing this made Caesar's heart froze. No matter how you listen to such a place, it feels very bad. Could it be that you have to practice in such a place next?

After only about 20 minutes, the Clan Raft withstood the gravel wasteland at its destination, and Lu and Caesar also moved to the ground on the teleportation array on the Clan Raft.

When he got to the ground and looked around, Caesar realized that this place was exactly the same as what Lu described. As far as the eye could see, there really was nothing at all except stones.

"Okay, then let's start training. Caesar, you first smash this stone with your bare hands."

"Empty hands means without using magic power?"

Lu nodded, and Caesar followed Lu's instructions and punched a huge stone in front of Lu into pieces.

"How's it going? Brother?"

Lu showed no expression, and then said to Caesar: "Let me demonstrate."

Lu walked to a stone nearby, and the stone in front of her was several times larger than the stone Caesar had broken before. It could be described as a hill.

"Aha!"

Lu's fist hit the stone directly, but under the power of his fist, the stone in front of him turned into powder and was destroyed, which was completely different from Caesar's attack.

"What, what's going on? Brother, why are your fists so powerful?"

Lu bent down and picked up a palm-sized stone on the ground and explained to Caesar: "Listen, second brother, if you want to completely break this stone now, you have to use your fist to exert impact on the stone. Only

However, stones, no, it should be said that any object in the world has corresponding resistance, and your impact will be offset by the resistance."

"But, I still broke the stone?"

"That's right, because your impact force is greater than the countervailing force, you can break the stone. But in this way, you also expend more energy. In this way, the impact force you received will also rebound, causing you pain.

.In other words, your efforts can be said to be in vain."

"So, brother, how did you do it?"

"I will tell you next, first, use your fist to hit the stone with the first blow."

After saying that, Lu hit the stone with ordinary force, and then continued: "At the moment when the resistance of the stone and your impact force cancel each other out, and the countervailing force has not yet been generated, use the

With the second strike, the impact of the fist will be fully released, and the stone will shatter just like before."

"This... always feels too simple."

"try it yourself."

Lu threw the stone in her hand to Caesar. After Caesar caught it, he immediately hit the stone with his right fist.

"broken!"

The stone in Caesar's hand was indeed smashed and turned into numerous gravels, but it did not turn into powder like Lu just demonstrated.

"Strange, it didn't shatter."

"You just punched twice in a row. You had to use extremely fast speed. To be precise, it is within 0.013 seconds. During this time, release the second punch against the stone."

Lu hit a stone next to him again, and the stone next to him immediately turned into dust!

"It took me a total of 2 months from Master Silufina to understand this principle and actually implement it. I don't know how long it will take you."

Caesar never thought that it would take so long to practice this trick, but for them, they only had one week left, and it was impossible to do it. However, Caesar laughed at this time

Said: "I swear in the name of the Demon King Solomon that I will practice this trick in two days!"

Once the Solomonic Oath is sworn but not completed, it will be a dead end in the end. Although Lu knew how to cancel the effect of this oath, Caesar spoke before that.

"If you don't risk your life to gain strength, then you won't be proud at all, so I have no choice but to do this, brother."

Lu also admired Caesar's courage to "bet his life". He just smiled and said to Caesar: "There is a stream at the end of the road. There is water to drink and fish to satisfy your hunger.

, I will pick you up in two days, hoping to see you who have already practiced this move."

"Okay, just look forward to it."

After saying this, Caesar walked to a stone nearby and started practicing with his fists.
Chapter completed!
