Lu finally escaped from Harwins' territory. If she continued to stay at that time, she was afraid that she would really make a big mistake. Fortunately, she finally escaped. However, tomorrow, she would have to take Elsia back. She was afraid that Elsia would definitely lose her temper at that time.

However, before returning to his room, Lu saw a familiar person at the door of the room.

"Second brother?"

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

"Did you say you're waiting for me?"

Caesar nodded and stood up from the sitting ground.

"Brother, I want to be even better."

From Caesar's eyes, it can be seen that he really wants to become stronger. It seems that in the third preliminary match of the Holy Martial Festival, he seemed to be very dissatisfied with his battle.

"How strong do you want to be?"

"At least it must be able to break Mitsunian."

Mithril is the most solid metal in both the human world and the demon world, which is recognized in both the demon world and the human world.

"……are you sure?"

"I'm sure."

After a period of silence, Lu finally spoke.

"Follow me."

Lu only said three words, but Caesar heard something from Lu's tone. He felt that Lu probably agreed to his request, but... it was probably very difficult to practice for himself.

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

Accompanied by the light hanging from the sky, Lu and Caesar's bodies 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 plans, he still followed Lu onto the clan raft. After entering the clan raft, Lu issued an order to the clan raft.

"The clan raft obeys the order, and the next purpose is to gravel wasteland."

The clan raft operation room had received the order, and it set sail towards its destination, the gravel wasteland.

"Brother, where is the gravel wasteland?"

"It's a wasteland where there is nothing but stones. There will only be a group of hungry vultures coming to attack humans anytime and anywhere. It's very fierce, but for you, it's the best place for you to practice."

Hearing this made Caesar's heart feel a little cold. No matter how you hear such a place, it feels very bad. Do you mean you will practice in such a place next?

After only 20 minutes, the clan raft blocked the gravel wasteland at the destination, and Lu and Caesar also moved to the ground on the teleportation array on the clan raft.

When I got to the ground and looked around, Caesar found that this place was exactly the same as what Lu described. Looking around, there was really nothing else except stone or stone.

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

"Empty-handed, is it just that without using magic?"

Lu nodded, and Caesar also punched a huge stone in front of Lu as Lu told him to smash it into pieces.

"How is it? Big brother?"

Lu had no expression, and then said to Caesar: "I'll demonstrate."

Lu walked to a stone beside him, and the stone in front of him was several times the size of the stone that Caesar had broken before, and could be described as a hill.

"Ha!"

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

"What's going on? Brother, why is your fist so powerful?"

Lu bent down and picked up a stone the size of a palm on the ground and explained to Caesar: "Listen to me, if you want to completely smash this stone now, you have to use your fists to exert impact on the stone. However, the stone, 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?"

"Yes, because your impact force is greater than the offset force, you can break the stone. However, in this way, you spend more effort, and the impact force you are subject to will rebound and cause pain. In other words, your strength can be said to be wasted."

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

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

As he said that, Lu smashed the stone with ordinary force, and then continued: "Just as the stone's resistance and your impact force cancel each other, and before the offset force was generated, a second attack was launched on the stone, so that the impact force of the fist could be completely released and the stone would shatter like before."

"This...is always too simple."

"You try it."

Lu threw the stone in his hand to Caesar. After Caesar received it, he immediately smashed 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, not crushed."

"You just punched two times in a row just now, and you have to use extremely fast speed. The correct way is to say that it is between 0.013 seconds. At this time, release the second punch to the stone."

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

"It took me two months to understand this truth from Master Silufina back then. 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, which was impossible to do. However, Caesar smiled at this time and said, "I swear in the name of the devil Solomon that I will practice this trick in two days!"

Once Solomon's oath was made but it was not completed, then there would be a dead end. Although Lu knew how to lift the effect of this oath, Caesar spoke before that.

"If it weren't for the power I gained from betting on my life, I wouldn't be proud at all, so I can only do this, brother."

Lu also admired Caesar's passion for "betting on life". He just smiled and said to Caesar: "There is a stream that can be drunk there, and there are also fish that can be used to satisfy your hunger. I will pick you up in two days, hoping to see you who have already mastered this trick."

"Okay, look forward to it."

After saying this, Caesar walked to a rock beside him and began practicing with his fist.

The stone was just broken into pieces, and there was no sign of shattering at all, but Caesar was not discouraged. He started practicing again against the already smaller stone.
Chapter completed!
