When Ouyang Baofeng did this, it wasn't that he didn't think of the consequences. On the contrary, he was known as the "Nine-tailed Fox"; he had meticulously and meticulously thought through his thoughts. He had thought about everything that would happen after the plague broke out. He had thought about everything too much.

Just as he had said, if there were any other options, he would never use such a method!

The plan that had been in his mind for a long time was to send troops to the northern region and spread the plague deep into its heart. They did not send troops to win the war. They sent soldiers to the north because they could not take care of themselves and would never be able to invade the north again!

However, no matter how good a plan was, it had to have an opportunity to be implemented.

When the late emperor was still alive, he had suppressed the development of the Northern Frontier and reduced its military strength. He had not even given the Wind Chasing Army any food, military assets, etc. Using this method, he continued to reduce the military power in Feng Qingxiao's hands. In order to resist the Wind Chasing Army, the size of the imperial guards had been expanded several times. The army of the imperial guards, which was originally only a few tens of thousands, had now expanded to over a hundred thousand.

Afterwards, in order to not let the imperial guards gain any power, they all landed in the hands of Yunfei Peak. Then, a portion of the imperial guards were dispatched to a nearby town to station, separating from the imperial guards.

Most of the troops that had previously been transferred from the capital to the northern border were now part of the imperial guards' army.

The army of the Northern Frontier that was being suppressed was in the hands of Feng Qingxiao. However, if they wanted to invade the Northern Region, they couldn't do so without an imperial edict. Otherwise, it would be treason. Ouyang Baofeng's body hadn't been in a good condition all this time, so this plan was put on hold. The plan had been set up by Ouyang Baofeng alone. He had never told anyone about it, nor had he ever secretly collected the source of the plague. He had also carried out every bit of secrecy and caution, to the point where not even Feng Qingxiao knew anything about it.

On his way back to the capital, Feng Qingxiao had been ambushed, assassinated, seriously injured, and even hit by the Soul Devouring Crossbow.

After Ouyang Baofeng learned of this matter, his heart burned with anxiety. The only thing he could do was to send out more Iron Guards and travel to Feng Qingxiao's side day and night. However, it was still too late. By the time the large group of Iron Guards arrived, Feng Qingxiao was already severely injured and had his chest pierced by the Soul Devouring Crossbow.

At that time, Ouyang Baofeng, who had received the news, only did one thing. He secretly sent out the most elite of the Wind Chasers and divided them into countless smaller units. Most of them were disguised as caravans, advancing towards the capital from every direction. His thought at that time was to take revenge for Feng Qingxiao, to allow the Wind Chasing Army and Iron Guard to secretly enter the capital and overthrow the Zhou Dynasty!

The reason why the change in the capital was so smooth was because Ouyang Baofeng had sent many of the elites of the Wind Chasing Army into the capital, or perhaps they were hiding outside the capital.

When Feng Qingxiao and the capital were in danger, the barbarians of the northern region had joined forces with the Rising Sun Empire to invade the northern border!

The situation was critical. Holding onto the sick Ouyang Baofeng, he led a hundred thousand soldiers of the Wind Chaser Army as they faced the assault of seven hundred thousand soldiers. Everything in the northern border needed to be dealt with by him, so the pressure on him could be imagined.

The situation in the capital was uncertain. With a war going on, how could they still care about the capital?

Even if Feng Qingxiao transformed the Tianyuan Kingdom, it would still take a long time for the capital to stabilize and the Tianyuan Kingdom to be completely stable. Even if the War God King had an extremely high prestige in the Tian Yuan Kingdom, the previous emperor was not benevolent nor righteous. If he wanted to seize the throne, the situation would not be stable for a long time. At this time, the Northern Region joined forces with the Rising Sun Empire to invade the Northern Frontier. They wanted to take advantage of the turmoil in the Tian Yuan Kingdom to gain benefits.

Time was the most crucial thing, and it was also what Feng Qingxiao lacked the most!

Because the Northern Region and the Sun Ascension Empire had seized the opportunity to raise their forces, they had no choice but to place the descendant of the Zhou family, the Thirteenth Prince of the late emperor, on the throne.

Ouyang Baofeng had no choice but to tighten the line of defense, giving way to many towns and cities. At the same time, he secretly set up a poison attack.

This method was to spread the plague source that had been hidden for a long time to some water sources, cattle, sheep, and even the areas occupied by the Northern Region and the Rising Sun Empire!

The spreading of the plague was also very well-planned. First, they would spread out the source of the plague, which had a long incubation period, before spreading it out faster and faster. Of course, Ouyang Baofeng would try his best to choose the most effective medicine and method to deal with this plague. He could control it and prevent it from spreading to the people of the Northern Frontier Army. There were drugs that could treat it. He had already prepared everything he needed to control and cure the plague. He was waiting for the right moment.

The Barbarian King knew that it was a good opportunity for the late emperor to destroy the Great Wall in the face of the feud between the kings of the Tianyuan Kingdom. It didn't matter if the emperor of the Tianyuan Kingdom was able to kill the War God King. He did not care if the victor was the Emperor or the War God King of the Tianyuan Kingdom, but rather this rare opportunity. He took the opportunity to join forces with the Sun Ascension Empire and invade the northern border. This was because the Emperor of the Tian Yuan Kingdom had assured him that the Battle God King would definitely die.

The previous emperor's confidence originated from the Soul Devouring Crossbow. This was not wrong, but it was a pity that he encountered Yun Zihuang.

This was an unforeseen event that had changed the history of the Tianyuan Kingdom!

Yun Zihuang had already concocted a medicine that could control the plague and cure the disease. Since she had time to use the super divine tool, hiding in the cabin was no problem at all. Not to mention that Ouyang Baofeng had already prepared all sorts of medicines and other items to control the plague, making them even faster and more convenient. The terrifying plague of this era, in the era of her planet, was basically nothing. Compared to the biological crisis, the viruses and bacteria in the space were just child's play.

Ouyang Baofeng faintly looked on. How old was this immature little girl?

To think that sixteen years old would know so much. Not only was his medical skill godly, he was also a genius in the military!

Was it bestowed by the heavens?

"What plague did you use in Black Bear Valley?"

She smiled slightly and said, "I can't compare to how generous you are. I didn't kill many people, not even many war horses."

"Indeed, I am not as vicious as you. Right now, the enemy army is killing at least a few hundred people every day. Actually, I did not wish for that many people to die."

"Oh, this isn't the personality of the Great Commander. You should be wishing that they would all die and become fertilizer for the Northern Frontier Land."

"No, at least I don't want to let all the enemy die."

His smile was gentle and gentle. "I hope that they will be able to return to their homeland alive."

"How vicious, are you trying to use the plague to kill off the barbarians of the northern region and the Rising Sun Empire?" Using this method to wipe out their entire country? "

"If I can do that, I'll die for sure. I've been preparing this gift for the barbarians of the northern region for far too long."

His tone was as casual as ever, yet it was filled with unforgettable hatred and endless ruthlessness!

"If you can control the plague and stop it from spreading in the north, make the plague disappear completely after the war ends. I can do whatever I want."
