Hearing Dong Tianyu ask this, Robinson William actually felt the same way, but the cautious Robinson spoke up and negotiated with Dong Tianyu, "Wait here for me, I’ll go over and confirm whether this guy is really dead or just pretending to be dead to deceive us both."

After finishing his words, Robinson cautiously approached the corpse of the medium-sized ancient creature. Unknown to him, as Dong Tianyu approached, he had already performed Spiritual Sense Scanning on the fallen medium-sized ancient creature.

After confirming that the heart of this medium-sized ancient creature had completely stopped beating, he also conveniently checked its brain with his Divine Sense.

By this time, there was no brain left inside the skull of the medium-sized ancient creature; only a mass of turbid liquid remained, and the missing liquid had started to flow out of the seven orifices of the medium-sized ancient creature.

The lethal effect of this custom-made bullet was entirely different from what Dong Tianyu had originally imagined!

Initially, upon seeing the thickness of the bullet, Dong Tianyu had thought that it was like a missile, supposedly filled with high explosives, which would detonate inside the target’s body once it penetrated, and directly blow the target to death.

But from the current situation, the bullet had penetrated through the body of the target, entering into its insides, yet what was contained inside the bullet was not an explosive.

Based on the condition of the ’unfortunate’ creature’s brain, the bullet seemed to be filled with some kind of highly corrosive chemical agent.

This chemical agent, in addition to rapidly dissolving the brain of the medium-sized ancient creature, should also have super stability, at least maintaining its original properties under high temperatures.

After all, as the bullet is fired, its temperature will gradually increase, and this agent could maintain its intended effects under such high temperatures, which ordinary chemical agents can’t achieve.

Looking at Robinson still carefully outwitting the air, Dong Tianyu somewhat helplessly gave Madeline a safe gesture from a distance.

Seeing Dong Tianyu’s gesture, the three people sitting inside the pickup truck saw it and Madeline then restarted the vehicle, quickly arriving beside Dong Tianyu.

It was only now that Robinson, who had just approached the skull of the medium-sized ancient creature, saw his brother driving over and immediately felt very angry, as he had yet to confirm the death of the target in front of him.

If Madeline rashly drove over, and the medium-sized ancient creature was only unconscious and not dead, the sound of the vehicle could wake up the merely slumbering prey, complicating the situation considerably.

Robinson was just about to reprimand Madeline for driving over when he suddenly realized that he had already reached the head of the medium-sized ancient creature. If he were to loudly scold Madeline now, it would be rather interesting if he woke up the creature lying on the ground.

Looking at Robinson about to speak but then forcefully holding back his words, Dong Tianyu couldn’t help but suppress a chuckle.

Dong Tianyu’s expression at this moment was fully witnessed by Robinson, who was so annoyed he wished he could take Dong Tianyu down with an unsparing glare.

When Madeline parked the pickup beside Dong Tianyu, Robinson knew he needed to speed things up; otherwise, if the three of them got out of the vehicle and an issue arose, waiting for them to get back on would cause significant delay.

Deciding to hasten the confirmation, Robinson leaped atop the skull of the medium-sized ancient creature in a few strides, first making sure the eyes were spiritless. He then pulled out his handgun and aimed at the massive eyeball beneath his feet, firing a series of shots in rapid succession.

Robinson was prepared while shooting, ready to swiftly escape from its head at any sign of resistance from the medium-sized ancient creature below.

But even after Robinson burst the eyeballs beneath him, the head underneath didn’t move at all, and it was then that Robinson could confirm that he had indeed taken down the colossal creature with a single shot.

Approaching the creature’s nostrils and testing with his hand to ensure there was no breath, Robinson then signaled safe.

Seeing Robinson’s gesture, Madeline called out to Dong Tianyu, "Get in, I’ll take you over."

Hearing Madeline say this, Dong Tianyu replied with a hint of disdain, "Get in your car? By the time it takes to get in, I would have already reached there." 𝒻𝑟ℯℯ𝑤𝑒𝑏𝑛𝘰𝓋𝑒𝓁.𝒸𝑜𝘮

Without waiting for Madeline to react, Dong Tianyu promptly moved forward.

Hearing Dong Tianyu say this, Ye Liuyun said indignantly, "So what if you have a high cultivation level? If you’re so capable, don’t ride in the car, just run back on your own."

The two sitting behind Ye Liuyun, upon hearing his Q-esque complaint, struggled to hold back their laughter, their faces turning red with the effort.

Just as Dong Tianyu had said, the moment Ye Liuyun had started moving, Dong Tianyu was already standing beside Robinson William.

Although he had already understood the situation inside the skull of the creature beneath his feet, Dong Tianyu still pretended to know nothing and said to Robinson William, "Do you want to open it and see what the condition is inside now?"

Upon hearing Dong Tianyu’s suggestion, Robinson William didn’t refuse, but since they had no suitable tools on them, they could only wait for Ye Liuyun to drive a pickup truck over.

Seeing Ye Liuyun and the three others get off the pickup truck, Robinson William shouted to the two recorders he brought, "Number Three, Number Four, take out the craniotomy device and open this guy’s head to see what the condition is like inside after being hit by the bullet."

This outing for weapon testing was not only for assessing the practical capabilities of the gun but also to understand the kind of damage a bullet would cause inside a target’s brain on impact, which was why they had specifically brought a craniotomy device designed for large creatures.

The so-called craniotomy device for large creatures was in fact just a chainsaw originally used for cutting trees. Number Three and Number Four put on protective gear and came over with the chainsaw in hand.

That Number Three and Number Four were chosen by Robinson William to come along indicated that their martial path cultivation level was not low, although they had not reached the Energy Cultivation phase, they were at the peak of the Inner Breath Realm.

After donning the protective gear, the two jumped onto the skull of the mid-sized ancient creature with the chainsaw in hand.

Seeing them approach, Dong Tianyu and Robinson William wisely moved away from there, both going back to the vicinity of the pickup truck.

The reason they didn’t remain at the site to watch Number Three and Number Four work was clear; just imagine the wood chips flying everywhere when a chainsaw cuts wood, and you would understand why they needed special protective gear for the craniotomy.

As for cold weapons sharp enough to directly cut through the skull of a mid-sized ancient creature, there weren’t any at the Saxon County camp, and even in Pengcheng, it was uncertain if any existed. Only weapons made of special alloy materials could easily sever the skull of a mid-sized ancient creature.

Most creatures’ skulls are among the hardest bones in their bodies; ancient creatures’ bones are even harder than those of humans. Although ancient creatures don’t cultivate, given their size, the Spirit Energy they passively absorb with each breath also subtly strengthens them.

Even though Number Three and Number Four used the chainsaw for the craniotomy, they had to change the chainsaw blade four times before they could completely open up the skull of the mid-sized ancient creature.

By then, Number Three and Number Four were covered in a thick layer of blood froth. The two wiped the protective goggles over their eyes before they exerted force together to pry open the skull of the mid-sized ancient creature.

The moment the skull was pried open, a pool of the same liquid that had been flowing from the creature’s orifices spilled out of the now open skull. Upon seeing that there were no solid remains inside the braincase, everyone except Dong Tianyu showed a look of shock on their faces.

They had originally thought the bullet would cause physical damage, but it turned out to have caused chemical damage on impact instead.

It was then that Robinson William and Dong Tianyu understood why the manual had stated, firing five bullets into the brain of a giant ancient creature could kill it.

Although it was still about destroying the brain of a giant ancient creature, they hadn’t expected it to be done in this way.

It was like besieging a city in ancient times, where the plan was to storm the walls and break through the gates with a large army.

But when it came to the actual siege, they chose to poison the city’s only water source, killing all living things inside instead.

Both were besieging the city, but the methods were as different as heaven and earth.

However, a great man once said, it doesn’t matter if a cat is black or white; as long as it catches mice, it’s a good cat.

Similarly, no matter the method, as long as it could kill the giant ancient creatures, it was good news for their camp.
