Dr. Sim, having witnessed Han Lang's unconventional fighting style, was beside himself with rage.
Yet, at this moment, he was utterly helpless.
Beyond passive defense, he found no opportunity to counter Han Lang.
The most critical issue was.
His situation was indeed as Dan Nan had described: the Golden Luo Illusion caused him immense depletion with each cast.
If he could sustain this depletion, perhaps it would be manageable, but to constantly switch like this.
Let alone him, even the cows in the pen would be worked to death!
After much thought, he cast a hateful glance at Han Lang and then initiated the familiar incantation.
"Boom!"
His golden form rose in response.
The towering figure nearly pierced the heavens.
"Heh! Is that all you've got?"
Han Lang remained unfazed.
He quickly repeated his tactic, transforming the golden pillars into golden needles and striking at Dr. Sim.
However, this time, as Dr. Sim faced Han Lang's persistent golden needles, his heart seethed with resentment.
He gritted his teeth and then roared in anger.
"Damn it! I'll kill you!"
Saying this, he opened his mouth and bit down hard, a drop of vital blood falling from his tongue.
Without hesitation, he spat it out.
Immediately, a mist of blood enveloped the golden form, imbuing the Golden Luo Illusion with a bloody ferocity.
Han Lang, unaware of the reason, felt a tremor of unease.
On the ground, Ma Long, who was equally clueless, burst into laughter.
"Heh heh, look! Dr. Sim is spitting blood! Does that mean he can't handle Young Master Han anymore!"
Zhao Wu and the others rushed to look, catching sight of Dr. Sim spitting blood.
They were perplexed.
While Han Lang had, in a way, suppressed Dr. Sim, it seemed too easy for him to make Dr. Sim bleed.
Moreover, the scene before them did not suggest any decline in Dr. Sim's aura.
As everyone was bewildered, Dan Nan's eyes suddenly widened, and he shouted in sheer terror.
"Not good! It's Blood Sacrifice! Blood Sacrifice!"
Everyone froze, turning their gaze to Dan Nan.
Han Lang, in the tense moment, quickly asked.
"Deputy Commander Dan, what is Blood Sacrifice?"
Dan Nan quickly explained.
"Blood Sacrifice is a cultivation technique that temporarily enhances strength using one's own vital blood! This technique was originally a cultivation method of demonic cultivators in our Xia Kingdom during ancient times!"
"Because, during the process of Blood Sacrifice, the entire person becomes exceptionally violent, even indiscriminate in their attacks! Their desire is for slaughter, their goal is blood! When encountering such cultivators, almost everyone chooses to avoid their锋芒!"
After Dan Nan's brief explanation, everyone couldn't help but gasp.
The entire battlefield, apart from their small group and Dr. Sim himself, had no other superhumans.
This meant that even if Dr. Sim became frenzied, he wouldn't be indiscriminate.
After all, he had no allies left!
The most dire situation was that, apart from Han Lang, everyone else was injured.
Even if they wanted to evade Dr. Sim's锋芒, it was impossible.
Was Han Lang supposed to abandon them and run?
That was unrealistic and almost impossible!
With these thoughts, everyone's expressions became grave.
"Deputy Commander Dan, are there any countermeasures for this situation? Or does the Blood Sacrifice technique have any weaknesses?"
Dan Nan swallowed hard.
"Blood Sacrifice is not a particularly high-level demonic cultivation technique. Its weaknesses are also fatal, but, for us, these weaknesses are practically unusable!"
Everyone quickly questioned.
"Why? Why can't they be used?"
Dan Nan sighed.
"Alas! Blood Sacrifice has two weaknesses. First, its duration is not long! If it encounters a powerful opponent, this method of temporarily increasing one's strength cannot bring the opponent to death. Instead, it greatly depletes oneself and reduces one's combat effectiveness!"
Hearing this, no one rejoiced.
Although this weakness of Blood Sacrifice was fatal, for Han Lang, who had finally managed to slightly gain an edge over Dr. Sim, any further increase in his strength, however small, was something Han Lang could not bear at the moment!
Moreover, even if Han Lang were to endure it, the twelve golden needles likely wouldn't last through the duration of the Blood Sacrifice.
Therefore, this weakness was practically unusable by them.
"What about the second one?"
Hearing Han Lang's continued question, Dan Nan looked at him with even greater terror.
"The second one. The second one is even more unusable! Because the vital blood consumed by Blood Sacrifice is said to contain life essence. This means that each use reduces the user's lifespan. Therefore, with each use, the user becomes extremely weak."
At this moment, Han Lang and the others were shocked.
This weakness was indeed something they couldn't exploit.
Because the biggest problem they faced was whether they could withstand Dr. Sim's first use of Blood Sacrifice.
If they could withstand it, let alone kill Dr. Sim, even forcing him to use it multiple times would cause him to exhaust his own lifespan.
There would be no need for Han Lang and the others to worry about killing him.
But the key was, how to counter the current Dr. Sim?
With these thoughts, Han Lang became momentarily at a loss.
Looking at the increasingly frenzied Dr. Sim, and recalling Dan Nan's explanation of the Blood Sacrifice technique, he dared not delay any further.
Before Dr. Sim could complete the Blood Sacrifice, he quickly transformed the twelve golden needles into larger golden pillars, like heavenly pillars descending from the sky, piercing straight down, forming an impenetrable cage, trapping Dr. Sim tightly within.
At the same time, he looked at Dan Nan again.
"Deputy Commander Dan. May I ask, what is the approximate duration of Blood Sacrifice? And how much life force is consumed?"
Han Lang was worried that.
If the duration of Blood Sacrifice was not particularly long, then perhaps he could employ some guerrilla tactics to stall for time, which might be effective.
And inquiring about the amount of lifespan consumed was to roughly estimate how many times Dr. Sim could use Blood Sacrifice given his age.
If the duration of Blood Sacrifice was short, but the lifespan consumed was also not much, wouldn't that be equivalent to extending the duration of Blood Sacrifice?
Therefore, he felt it was essential to grasp this information.
"The duration of each Blood Sacrifice is approximately three to five minutes. Each use consumes about five years of lifespan!"
What?
Three to five minutes?
Only five years?
Dr. Sim, at this moment, appeared to be only around fifty years old.
If he could live to eighty, then he could use Blood Sacrifice a total of six times.
This translated to approximately eighteen to thirty minutes!
In a battle of this magnitude, let alone ten minutes, even two or three minutes would be an ordeal!
Seeing Han Lang's astonishment, Dan Nan seemed to understand his thoughts and quickly explained.
"No, Han Lang! You've misunderstood. The duration of Blood Sacrifice is not calculated like that!"
