Oh no! I, the weakling, have become the villain!

Chapter 647: Pills

"I have a secret medicine that can increase a human's strength after consumption, but it can only be taken three times," Xu Yao said.

"A secret medicine?" The envoy from Qing Teng City's eyes lit up.

"The method for making this pill has been lost long ago, and no one can make this kind of elixir."

"Moreover, the ingredients for this elixir are extremely precious; even our Qingyan City may not possess them," said the envoy from Qingyan City.

“We really can’t get our hands on this kind of pill; we lack the necessary materials right now,” Xu Yao said calmly.

"No wonder you're so confident. So you have something like this. Then what are you talking about?" said the envoy from Qing Teng City.

"Don't we have a cooperation agreement?" Xu Yao countered.

"I have agreed to your demands, so you must guarantee that the threat of the demons will not affect your Qingyan City," the Qing Teng City envoy said with a grim face.

"I promise I won't. As long as you don't invade our Qingyan City, we will absolutely not take action," Xu Yao said confidently.

"Are you telling the truth?" The envoy from Qing Teng City looked at Xu Yao with suspicion.

“Of course, what I said is true, but I want your city,” Xu Yao said calmly.

"You want our city? Don't you humans never bother to fight for our cities?" the envoy from Qing Teng City said sarcastically.

"Our Qingyan City simply disdains to contend for this place; it doesn't mean we can't attack Qingteng City."

“Moreover, your city has already been breached, and you no longer have any advantage,” Xu Yao said.

The envoy from Qing Teng City fell silent; he truly had no way to stop the human race.

Because a large number of human troops are already heading to Qingyan City, it is estimated that the human army will arrive in Qingyan City soon.

Upon receiving the news, the city lord of Qing Teng City immediately led the people of Qing Yan City to meet the enemy.

The soldiers were overjoyed to see their lord return.

Xu Yao followed the soldiers of Qingyan City to the city wall.

Looking at the dark mass of demon soldiers below, everyone in Qingyan City tensed up.

"Don't be afraid. They're just testing the waters. Once they've figured out our strengths and weaknesses, they'll attack directly," said the city lord of Qingyan City.

The soldiers of Qingyan City calmed down a bit after hearing the words of the city lord.

"Brothers, charge!" the soldiers of Qingyan City shouted.

Upon witnessing this scene, the demon soldiers excitedly charged towards the city of Qingyan.

The two sides clashed, and the battle lasted for half a day before the demons emerged victorious.

Qingyan City was completely occupied, and the city lord of Qingteng City was killed by the demons.

"These people from Qing Teng City are really stupid," Xu Yao remarked from the side.

"What do you mean by that?" The soldiers of Qingyan City glared angrily at Xu Yao.

"The demons have now breached your Qingyan City, and they have killed your city lord."

"You should be praying they attack the city quickly," Xu Yao said with a smile.

“You…” The soldiers of Qingyan City looked surprised after hearing Xu Yao’s words.

"How is this possible? How could our city lord have been killed by them?"

"Didn't I just say that the demons are much stronger than your city lord? Your city lord is no match for the demons at all."

Xu Yao continued speaking.

The people of Qingyan City were filled with shock; they had never imagined that the demon race would be so powerful.

They had always thought the demon race was a weak race, never expecting them to possess such strength.

Moreover, judging from the demons' formation, they were clearly preparing to take over their Green Vine City.

This instilled a strong sense of crisis in the soldiers of Qingyan City.

"Let's go," Xu Yao said.

"Are you really willing to give up your Qingyan City?"

“Of course,” Xu Yao replied without hesitation.

"Haha, you're really adorably silly," said a person from Qing Teng City.

"Let's go." Xu Yao ignored him and walked out directly.

"Where are the people from Qingyan City?" The people from Qingteng City found Xu Yao in the city lord's mansion of Qingyan City, but they couldn't find any people from Qingyan City.

"Please wait outside for a moment, I'll be right out," Xu Yao said.

The envoy from Qing Teng City watched Xu Yao's retreating figure without saying anything, after all, Xu Yao had saved their lives.

Moreover, the people of Qing Teng City had their troubles resolved by Xu Yao, so they still needed to listen to Xu Yao.

After the people from Qingyan City left, Xu Yao took out a pill and swallowed it. His strength had now recovered to the Martial King level.

Although it has only been a few short years, Xu Yao's cultivation level has increased rapidly.

Xu Yao's strength has now reached the peak of the ninth-level Martial Emperor, only one step away from the Martial Grandmaster realm.

Moreover, Xu Yao's body contains a trace of dragon energy, and his strength is constantly increasing.

"Now I should be able to easily defeat ordinary peak Martial Emperor experts, and even challenge Martial Venerable level experts."

Xu Yao muttered to himself.

During this period, in addition to studying alchemy and formations, Xu Yao also took time to comprehend sword and saber techniques.

During this time, he also learned a lot of martial arts skills and techniques.

Xu Yao's strength is improving too slowly, so he needs to take some concrete actions to stimulate his own growth.

"The system helped me display the map of Qing Teng City," Xu Yao said.

A map of Qing Teng City quickly appeared in Xu Yao's mind.

"The city wall of Qing Teng City is located at the south gate, which is also the only city gate."

"Once the gates of Qing Teng City are breached, Qing Teng City will fall."

Xu Yao carefully observed the surrounding situation and found that the defenses of the entire Qing Teng City were not very tight.

Once they break down this city gate, they can launch a surprise attack on Qing Teng City at night.

"Alright, if that's the case, then let me see how strong Qing Teng City really is," Xu Yao said with a cold smile.

"System, summon a high-level demon for me," Xu Yao said.

Then a flash of light appeared, and a man riding a white tiger appeared in front of Xu Yao.

"Your subordinate pays respects to your lord," the man said respectfully, kneeling on the ground.

"Hmm, do you know how to do it?" Xu Yao asked.

"Rest assured, my lord, I will make the people of Qing Teng City pay a heavy price," Bai Hu said in a low voice.

"Good that you understand. Go ahead," Xu Yao nodded and said.

Meanwhile, in a house within the city of Qing Teng.

A group of people sat together discussing matters, including the city lord of Qing Teng City and the general of Qing Teng City.

"Lord, what should we do now? The demon army is almost here," the general of Qing Teng City said with a grave expression.
