I am the son of the Dragon God in Douluo Continent.

Poseidon Lake is an artificial lake built by Shrek Academy to commemorate Tang San, the leader of the Shrek Seven Devils ten thousand years ago.

In the center of Poseidon Lake is an artificial island, and on that island stands a towering, golden tree.

The artificial island is called Poseidon Island, and the towering tree is Shrek Academy's proud Golden Tree. The Seagod Pavilion, which protects Shrek, is located deep within the Golden Tree.

As mentioned before, Shrek Academy is divided into an inner court and an outer court, with the inner court being the core of Shrek.

Its teaching methods far surpass the content taught in the outer academies. This is why there is a saying that only students within Shrek Academy's inner academy are true Shrek students.

This leads to the fact that the biggest goal of every student who enters Shrek Academy is to join the legendary Inner Court, and the school will use various means to encourage students from the Outer Court to do their best to enter the Inner Court.

One of the methods is to let the new students experience the environment outside Poseidon Lake.

The spiritual energy around Poseidon Lake is not as concentrated as that of Poseidon Island in the center of the lake, but it is still much more concentrated than the spiritual energy outside.

Therefore, if one cultivates outside the Sea God Lake, the cultivation speed will be appropriately accelerated. Thus, the Sea God Lake is not only regarded as the location of an inner courtyard, but also as a sacred place for cultivation.

This is why many students from other departments take time to cultivate outside of Poseidon Lake.

However, unlike the usual tranquil atmosphere of Poseidon Lake, it was rather noisy today.

"I really can't do it! That won't work!"

"Heh, you were so stubborn just now, now you know it hurts? You'd better just give in!"

"No! That's too big! I really can't take it!"

"Come on, don't be afraid, it will be over soon."

"No... Ugh!!!"

A girl with pink and blue hair was crying and shouting on the outskirts of Poseidon Lake, while a boy watched her predicament with a smile.

If a normal person heard this bizarre conversation, they would surely think that the man and woman must have done something unbelievable.

However, fantasies are beautiful, but reality is harsh.

Therefore, if anyone has any impure thoughts, they should quickly slap themselves as punishment.

As Wang Dong'er put on an extremely strained expression, many steel balls of varying sizes floated around her.

Xu Xingyu watched Wang Dong'er's "hard work" as if it were a spectacle, and would occasionally throw a few steel balls to fuel her fire.

So why were Xu Xingyu and Wang Dong'er doing such a thing at Poseidon Lake so early in the morning?

This all started yesterday when Jiang Nannan explained why her mental strength and cultivation had improved to the level of a near-Soul King in just a few years.

After Jiang Nannan explained her situation, everyone went to the dormitory building, said goodbye, and returned to their respective dormitories.

Back in her dormitory, Wang Dong'er felt a sense of crisis due to Jiang Nannan's rapid improvement in strength. Although she and Xu Xingyu had the ability to fuse their martial souls to enhance their cultivation speed, this cultivation method could not improve their mental strength.

Although Wang Dong'er doesn't rule out forming an alliance with Jiang Nannan to overthrow the Great Demon King Gu Yuena and the Little Witch Xu Yanxue, and then sharing Xu Xingyu together, that's ultimately only on the premise that she is the rightful wife.

If Jiang Nannan's strength and cultivation speed far surpass his own, then it will be questionable whether Wang Dong'er will be able to win the position of the main wife when the alliance ends!

Therefore, Wang Dong'er must cultivate even more diligently now. Her soul power is alright, and the fusion of her martial soul with Xu Xingyu allows Wang Dong'er's cultivation speed to be no less than Jiang Nannan's, who has activated a physical cheat.

However, in terms of mental strength, Wang Dong'er can only cultivate passively at this stage and cannot cultivate actively.

Therefore, that night Wang Dong'er asked Xu Xingyu to help her train her mental strength starting the next day.

Xu Xingyu was shocked when she heard Wang Dong'er's request. After all, although Wang Dong'er had been cultivated in the Spirit Pagoda since childhood, which made her more serious about cultivation than in the original story, she would still find time to slack off a little.

It's rare for someone to actively request this kind of special training.

Xu Xingyu felt like a father who had watched his daughter grow up, and was pleased that his daughter was becoming more and more mature.

Of course, Xu Xingyu could guess that the reason why Wang Dong'er made such an unusual attitude was mainly because she felt a sense of crisis due to the widening gap between herself and Jiang Nannan.

However, Xu Xingyu, who had already accepted the fact that he was a scumbag, only wanted to say, "You don't need to worry, I will never let go of anyone!"

For no other reason than that you are all my best wings!

Of course, Xu Xingyu only dared to say these things in her heart at this stage. If she really wanted to say them to people, she would wait until she was strong enough to defeat them all, so that she wouldn't be surrounded and beaten by her lovers.

Returning to the previous topic, after learning that Wang Dong'er wanted to undergo special training in mental cultivation, Xu Xingyu began planning that very night how to train Wang Dong'er's rudimentary mental strength.

Wang Dong'er was initially happy that Xu Xingyu was so heartbroken about her situation, but she regretted it the next morning.

The next day, around six o'clock in the morning, Xu Xingyu woke Wang Dong'er up from her sleep.

Wang Dong'er wanted to argue, but after Xu Xingyu said, "A day's plan starts in the morning," Wang Dong'er could only accept the fact and obediently get up.

After letting her sober up, he disregarded Wang Dong'er's objections and dragged her to the shore of Poseidon Lake to begin Wang Dong'er's training.

Xu Xingyu's training plan for Wang Dong'er was to have Wang Dong'er use her mental strength to lift these special steel balls.

These so-called steel balls are beads made of a special metal; they are small in size and not heavy.

However, this steel ball has a strange property: if it comes into contact with mental energy, it will generate a suction force that absorbs the mental energy.

Therefore, if a Soul Master uses their mental power to lift these steel balls, they will feel that the balls are unusually heavy because of this suction force.

However, the Soul Master's spiritual power was not absorbed by those steel balls for nothing.

In fact, once a Soul Master's spiritual power enters the steel ball and is absorbed to a certain extent, the Soul Master can use Soul Power to extract the spiritual power that was previously absorbed.

The extracted mental energy is of higher quality than the mental energy that enters the steel ball. Therefore, if one repeatedly allows their mental energy to be absorbed and extracted by the steel ball, their mental energy level will increase significantly in a short period of time.

The only thing to be careful about is not having a large amount of mental energy extracted by the steel ball at once, otherwise it could be life-threatening.

It is best to calculate based on the Soul Master's own spiritual cultivation level, and use a certain number of steel balls every day. As the spiritual cultivation level increases, the number of steel balls used for training can be gradually increased.

At first, Wang Dong'er didn't take this training seriously, thinking it was just a child's game and not a high-difficulty training at all.

However, after she started lifting the fiftieth steel ball, she began to feel a strain, and it was clear that Wang Dong'er could feel that she was about to give up.

What terrifies Wang Dong'er is that if a few more steel balls are added, she might be completely drained by these terrifying steel balls.

Therefore, Wang Dong'er pleaded with Xu Xingyu, saying that today was only the first day of training, and it was unnecessary to go to such lengths.

Xu Xingyu said that precisely because it was the first day, she needed to know where the student's limits were in order to plan how many steel balls to use for training in the days to come.

So Dong'er, don't be afraid, I will keep you safe and sound, just a few more pills will do.

Faced with Xu Xingyu's devilish words, Wang Dong'er could only weep with resentment and continue to increase the number of steel balls. Finally, after reaching seventy-five steel balls, she could no longer hold on, put down the balls, and collapsed to the ground.

"Seventy-five steel balls, not bad. It seems you haven't neglected your mental cultivation too much these past few years."

Hearing Xu Xingyu's evaluation of her, Wang Dong'er said irritably, "Xingyu, you've gone too far! I clearly told you I had Grandma Zhou's PE class today, and now you've made me completely collapse on the ground. What if I don't meet that teacher's requirements today? I might get thrown out!"

Hearing this, Xu Xingyu replied nonchalantly, "Don't worry, just recover quickly before class starts. Okay, hurry up and absorb the spiritual energy inside the steel ball. If you absorb too slowly, you might miss breakfast today."

"Can't you just take a breather before you start?"

"cannot."

Faced with Xu Xingyu's impartial order, Wang Dong'er had no choice but to obey and began absorbing the spiritual energy within the steel ball.

When Wang Dong'er absorbed the spiritual energy from the steel ball, it was like drinking a sip of pure water in a dry desert—a very refreshing feeling.

If Wang Dong'er hadn't had strong self-control, she probably would have already let out a sound of pleasure.

Xu Xingyu watched as Wang Dong'er began rapidly absorbing spiritual energy, and then began to observe the surroundings in case any emergency occurred.

After all, if one is interrupted while absorbing spiritual energy, it could potentially cause mental harm to that person if one is not careful.

After checking, Xu Xingyu didn't find anyone.

Wang Dong'er quickly extracted all the spiritual energy from the steel balls.

But just then, Xu Xingyu spotted a red dot on the Sea God Lake that was gradually approaching the two of them.
