Lin Wu saw that he had more than enough spirit qi to continue upgrading thus that's exactly what he did.

"MORE! MORE! MORE! Upgrade again!" Lin Wu ordered the system.

~Ding~

——

UPGRADING CULTIVATION BASE: please wait patiently.

——

The heat that was assailing the sense of the three men Shirong, Ye Dai and Bei Wen was increased once again and they could do nothing this time. They were already standing at the very edge of the isolating formation array and they definitely could not leave it or that would expose the presence of the spear.

"Use all your defensive techniques and tools!" Shirong spoke.

A bell shaped barrier surrounded Shirong as he used his defensive technique. Ye Dai pulled out a long feather from his ring and broke it, this created an armor made out of features on his body. Bei Wen used a different technique and a curtain of wind surrounded him.

With the defensive techniques activated, the three men were able to take a breath of relief.

"Reserve your spirit qi and keep the spirit stones handy, we don't know how long this will last," Shirong said in a serious tone.

The green crystal spear was still spinning, and the spirit qi the air was gushing at it, rapidly being absorbed. Because of his spirit sense being restricted by the pressure exuded by the spear, Shirong could not estimate the quantity of the spirit qi.

But from the looks of it, it was quite a massive amount.

~Ding~

——

UPGRADE COMPLETE: Host's cultivation base has reached the Mid stage of the core condensation realm.

LIFESPAN: 300 years

HOST CULTIVATION: Mid stage of the Core Condensation Realm

-Spirit Qi required to upgrade = [0000/12000] units (liquid spirit qi)

QI STORAGE: 4502 units [liquid spirit qi]

——

Finally, after ten minutes, Lin Wu had entered the mid stage of the core condensation realm. He looked at the remaining amount of spirit qi and the amount needed to upgrade to the next level.

"If I'm able to keep up this pace, then I should be able to upgrade to the next level in a few days or weeks." Lin Wu muttered to himself.

But just as he said this, he suddenly felt something happening inside his body.

"Aargh! What… is this pain?!" Lin Wu wondered.

For some reason, a pain was assaulting Lin Wu deep within his body.

"System, what is happening?" Lin Wu questioned.

~Ding~

——

ANSWER: According to the system's analysis, everything is within the normal parameters, yet the host seems to be under some kind of distress. This could only mean that whatever is happening, it is not recorded in the system's Data banks and cannot be detected by the system.

——

"AH! Dammit!" Lin Wu cursed.

He started to think what it could be, but could not come up with anything. But Lin Wu didn't know that he was not the only one who was feeling the pain. Shirong and his two companions were also burning up now.

For some reason, their defensive techniques were not working anymore and blisters had started appearing on their skin.

"Young master, we have to retreat farther or I fear we may not come out of this unscathed." Ye Dai said with urgency.

But before Shirong could even answer, he suddenly felt his vision going dark. And along with him, the vision of Ye Dai and Bei Wen went dark as well.

Unknown to Lin Wu, a strange Aura was being released from his body. The aura had covered the entire isolating formation and was still growing.

~Pop~

The formation could not hold on anymore and shattered the next second, releasing all the spirit qi that was being restrained. It was as if a dam was broken and Lin Wu's aura spread in an area of two hundred kilometers. It even reached the Deer Wood city and every cultivator in it felt it. The ones that were stronger felt their vision going dark as well.

But this was merely the start of the nightmare as soon they started seeing things.

A pair of eyes appeared in their vision. The eyes were blood red and had purple outlines to them. The size of the eyes was massive through and the people thought as if they were mere ants compared to them. Every single inch of their bodies was filled with absolute terror as they froze in place.

Shirong and his two followers saw this as well. Thought this was not the first time that Ye Dai had seen these eyes. Back when he had touched the spear for the first time, he had the illusion that he had seen these eyes. But at that time he thought it was due to bloodline suppression.

This lasted for an entire minute, which to all the people was as if hours had passed by.

~Ding~

Lin Wu took control of his wits after the pain faded away. But he realized that his form had changed, and he was back to his full sized worm form instead of the spear one.

"What! Dammit, it must have happened during the pain!" Lin Wu cursed and got ready to defend.

But to his surprise, Shirong and his two followers were knocked out cold. The three men were the closest to Lin Wu and had thus borne the full brunt of the pressure. Their clothes were torn and burned in multiple places, and their skin was covered in blisters.

Lin Wu took a look and was shocked.

"Seems like the heat from Radiation manipulation got quite high." Lin Wu muttered to himself.

In order to make it flashy, Lin Wu had asked the system to do some things while he broke through. This was also to mask his breakthrough and hide that he was actually a beast. He knew that radiation did not work well with spirit qi for others, and thus used the radiation manipulation skill to suppress the senses of the three men.

'I should return to my spear form quick before they wake up and then take a look at what's changed.' Lin Wu thought.
