The reason it is called a secret technique, rather than a cultivation technique, is because the use of secret techniques can have side effects and aftereffects, which makes them less desirable compared to cultivation techniques.
Sure enough, hearing that Lu Yu's method to temporarily increase spiritual power by slaughtering monsters was a secret technique, the Core Formation Realm experts lost interest.
"This is easy to handle, I will immediately order people to bring enough monsters here." The City Lord promptly agreed and ordered the generals beside him to have the soldiers gather some monsters into a designated area.
Soon the orders were given, hundreds to thousands of monsters were herded by the soldiers into a specific zone. The City Lord of Beifeng City acted, suppressing a massive amount of spiritual power, directly devastating all the monsters within that area.
"Young friend Lu can enter now, you need a demon-breaking weapon..." The City Lord of Beifeng City paused midway through his sentence.
Lu Yu drew the Demon-Breaking Saber and walked into the horde of severely wounded monsters. With a single slash, the saber light imbued with demon-breaking power cut through the bodies of dozens of heavily injured monsters, annihilating the demonic qi within them and reaping their lives.
[Killed a demon person, gained 320 experience points]
[Killed a demon beast, gained 500 experience points]
[Killed a demonized monster, gained 2356 experience points]
The kill notifications were swiftly scrolling, one swing of the saber could earn Lu Yu tens of thousands of experience points.
Each slash consumed 30 points of Lu Yu's spiritual power. He could swing 18 times, and as he ate spirit fruit to restore his spiritual power, gaining a million experience points wasn't an issue.
The City Lord of Beifeng City watched Lu Yu with the Demon-Breaking Saber in hand with a complex emotion in his heart. In some sense, the monster calamity began with the person who took away the Demon-Breaking Saber standing before him.
Yet now, he had to rely on this person who caused such a disaster to end this calamity.
Ling Yuyan was full of astonishment. She hadn't expected that the culprit behind series of incidents was actually right before her eyes. Her emotion was very complex, filled with resentment and anger, and she was at a loss. She opened her mouth but didn't speak, eventually falling silent.

Towards Lu Yu, her feelings were extremely complex. This man who had once brought her joy and unique experiences had now become the culprit who caused her most respected mentor to suffer disaster. She didn't know how to face Lu Yu and could only remain silent.
Yang Jiawei was stunned upon seeing the Demon-Breaking Saber in Lu Yu's hand. His veins stood out on his temples as he glanced at the City Lord and Ling Jingtian before calming down, looking at Lu Yu with cold eyes.
Yang Zhi had told him that Yang Xiu died in the Sealed Demon Forbidden Area. He had assumed it was because Yang Xiu was slain by a demon general. But now, seeing Lu Yu with the Demon-Breaking Saber, Yang Jiawei understood that it was very likely his son had been killed by Lu Yu.
Moreover, Yang Jiawei remembered that when Yang Xiu had returned from that remote small town, he had complained to him about a guy named Lu Yu who had ruined his affairs…
After gaining enough experience points, Lu Yu upgraded the Dou Shen Jue, enhancing his spiritual power.
Upgrading the Dou Shen Jue to increase spiritual power didn't show data, but Lu Yu could still clearly feel the enhancement of his mental power.
The most obvious change was that one slash which used to consume 30 spiritual power now consumed 29, improving the efficiency of spiritual power usage.
Noticing the changes in Lu Yu, everyone believed what he said about having a secret technique capable of temporarily enhancing spiritual power through slaughter.
Someone couldn't help but marvel at the creator of this secret technique, completely unable to understand the principle behind it.
The first ten levels of the Dou Shen Jue required only 100,000 experience points per level for enhancement. With help from others, Lu Yu swiftly harvested experience points and quickly advanced Dou Shen Jue to the sixth level.
Upon reaching the sixth level, Lu Yu felt his head swell and couldn't continue upgrading the Dou Shen Jue for the time being as his mental power had already reached its limit.
After continuing the slaughter for a while, he accumulated experience points up to a million and paused the slaughtering of monsters.
"I have already reached the limit that the secret technique can achieve. My current spiritual power is enough to support me in finding the demon lair," Lu Yu said to the City Lord of Beifeng City.
Under the lead of the City Lord of Beifeng City, everyone handed over the divine soldiers they had refined to Lu Yu. Their divine soldiers shrank to the size of a finger, making them easy to carry.
When Lu Yu accepted Yang Jiawei's divine soldier, he felt something slightly different compared to the others' divine soldiers. Upon taking a closer look, he found that Yang Jiawei bore some resemblance to Yang Xiu, which instilled a sense of caution in him.
With everyone's divine soldiers, Lu Yu used Earth Escape to sink into the ground, feeling the divine soldiers linked to his mind drifting further away. The crowd felt a slight unease being in the hands of others.
Everyone sat quietly in the military tent, feeling the distance growing with their divine soldiers, anxiously waiting for Lu Yu's news.
Suddenly, everyone felt their divine soldiers, linked to their minds, instantly vanish, causing great alarm. They stared angrily at Ling Yuyan and demanded, "What's going on?"
Even if stored in storage bags, they could still sense their divine soldiers, but now, they couldn't feel where their divine soldiers had gone!
Ling Jingtian was also anxious as his divine soldier had also disappeared. However, seeing everyone questioning Ling Yuyan, he calmed the crowd, telling them to settle down.
As Lu Yu was descending, he suddenly received a system prompt indicating that someone in the real world was approaching him. Finding a sealed underground cave, he deployed all his defensive spiritual treasures, activated the defense array and concealing array, locking himself inside the cave and forcibly exiting the game.
His body turned into a mound of earth within the cave, and the spiritual treasures, arrays, and divine soldiers surrounding Lu Yu were also forcibly erased in existence, merging seamlessly with the earth. No person or creature could distinguish them from the soil.
Forced to exit the game, amid the system's red alert sound, Lu Yu felt his body tearing apart and his soul being forcibly extracted from his body while his mind spun with severe dizziness, a hundred times worse than the first time he was transported into the Divine Weapon Pavilion Secret Realm.
The sensation was nearly lethal!
In reality, Lu Yu suddenly sat up, panting heavily as though he had just experienced death.
Hearing sounds from outside the door, Lu Yu removed his helmet...
