Although Neptune was able to detect everything within a kilometer of Gu Ding's location, taking things into their bag was another matter. Under his detection range, Neptune still needed a medium to touch the corresponding items in order to store it in their Inventory. At that time, insect robots were their best choice.

While the insect robots went off to do their job, Gu Ding started refining the medicine.

By the time Lawton and Arthas came back, Gu Ding had refined a tube of medicine. It has to be said that Gu Ding had already slowed down his refining speed to try his best.

When Lawton saw the color of the medicine, he was a little surprised. "Perfect quality?!"

"Seems like a lucky day!" Gu Ding casually replied. His hands did not stop as Gu Ding continued to refine the second tube of medicine.

Lawton and Arthas brought more medicinal materials over to the tent.

After entering and exiting the tent four times, the two of them finally fulfilled the list of medicinal materials that Gu Ding had requested. By that time, Gu Ding had finished refining five bottles of medicine, all of which were of perfect quality. Lawton was a little stunned when he saw it.

"Can I stay?" Arthas was obviously interested in medicine refinement as he looked at Lawton with wishful eyes. 

"It depends on whether mister pharmacologist agrees to it or not. Your presence may affect his work." Lawton was not sure about leaving Arthas there. Arthas was a genius in the tribe even though he was just a Level 1 Gene Body. As for the pharmacologist of unknown origin, Lawton was still wary of him.

"As long as you don't disturb me. If you do, I'll kick you out," Gu Ding said with a blank expression. Gu Ding did not like Arthas since he was going to become a G.o.d in the future. After all, Arthas was going to cause a lot of harm to humans in the Middle Ages.

"Mister pharmacologist, I promise to watch by the side." Arthas looked at him with the same hopeful expression.

Gu Ding nodded. Arthas was still an ordinary kid, so Gu Ding had no intention of making it hard for him.

Arthas sat quietly in the corner of the room as he stared closely at Gu Ding's hands so that he would not miss a thing. Gu Ding ignored him and focused on refining the medicine.

By the next morning, Gu Ding had refined more than one hundred and fifty bottles of medicine. Only two out of all those bottles were of ultimate quality, the rest of them were of perfect quality.

Gu Ding looked up to see where Arthas was. Arthas was still seated in the corner with his eyes wide open, and he was looking at Gu Ding with admiration. "You're so good."

"Thank you." Gu Ding was very happy to hear Arthas praise him. Gu Ding had not expected Arthas to stay up all night to watch him refine medicine without making a sound.

"Are you interested in medicine refinement?" Gu Ding could not help but ask.

"Yep!" Arthas nodded vigorously.

"Do you want to try it? E-grade might be a bit difficult for you, so you can start with F-grade first," Gu Ding said as he picked out several kinds of materials and started to refine them. Under less than two minutes, Gu Ding managed to refine a bottle of F-grade Cell Enhancer.

"Find a place and try it out yourself. Don't try to refine it here, you might cause an explosion and affect all the medicines that I've refined." Gu Ding threw a handful of materials toward Arthas and sent him out of the tent.

Arthas took the materials and left the tent in great excitement.

At that time, Lawton was on his way over to Gu Ding's tent when he saw the materials in Arthas' hands. He frowned and said, "Arthas, where did you get those materials from?"

"Master Pharmacologist gave them to me. He even taught me how to refine an F-grade Cell Enhancer." Arthas looked very happy.

"You were there all night?" Lawton could not help but ask.

"Yeah. Master Pharmacologist is very good at medicine refinement. He managed to refine most of the medicine to perfect quality," Arthas praised Gu Ding as if he wors.h.i.+pped him.

When Lawton heard that, he stopped asking questions and rushed into the tent. When he saw piles of perfect quality medicine laying around on the ground, he was a little stunned. "It's no wonder the high priest said that he was a pharmacologist genius..."

"I already used up quite a lot of my spirit, so it was hard for me to focus on the last two bottles. I'll rest for an hour. You can wake me up when the time comes and I'll continue refining." Gu Ding laid down on a bench made out of rattan and slowly closed his eyes.

Lawton initially wanted to refute and ask Gu Ding to continue his work. However, seeing the perfect quality medicines, he decided to keep his mouth shut. He turned to leave the tent and headed right for the high priest's tent.

"He managed to refine more than one hundred and fifty bottles of medicine in one night, and almost all of them are of perfect quality!" Lawton reported the matter to the high priest in his tent.

"I know." The high priest did not seem surprised by Gu Ding's medicine refinement ability. "Just keep an eye on him. If anything happens, come straight to me."

Lawton soon exited the tent.

Then, the high priest's finger moved and the tent's door immediately closed shut. Next, the high priest took out a golden chalice and placed it respectfully on the ground in front of him. He proceeded to take a knife out, slashed his wrist, and allowed his crimson blood to flow into the chalice.

When the blood began in the chalice began to overflow, he moved his fingers over his wound and it healed in an instant.

Subsequently, he began to speak in strange tongues that could not be understood.

About a few minutes later, the amount of blood in the chalice began to decrease slowly, and a black mist slowly started to condense above the chalice.

"The great Witch G.o.d, please guide us!" The high priest knelt respectfully on the ground.

"Regardless of whether the amount of medicine refined is enough, kill the three outsiders before sunset tomorrow. I can only last until then for this time's s.p.a.ce-time backtracking..." The black mist was erratic and a weird voice was heard from it.

After that, the blood in the chalice dried up completely and the black mist dispersed into the air.

What the high priest was unaware of was a mosquito had landed on a gla.s.s just a few steps away and witnessed the entire scene.

Neptune had seen everything through the mosquito robot. He thought about it for a moment before he told Gu Ding about it.

"This s.p.a.ce-time backtracking is man-made?" Gu Ding was puzzled. "But didn't you say that even G.o.ds aren't able of doing this kind of thing?"

"Some G.o.ds are weak and some G.o.ds are strong. This Witch G.o.d in particular seems like a very powerful existence. To be honest, I never thought a G.o.d of this caliber existed." It was completely out of Neptune's data records. That was why he had the wrong impression regarding the matter. If it were not for Robert's robots, the three of them would not have known what they were going to have to face.

"Before sunset tomorrow... How are we supposed to escape from a Level 12 Gene Body?" Gu Ding frowned.
