If Tang Yin wanted to personally go to the Yan City to save people, the civil officials and military officers naturally would not agree. They believed that it was extremely dangerous, and as the commander in chief of their side, there was no need to personally take the risk.

Qiu Zhen was opposed to this at first, but after thinking about it, he remembered that Tang Yin had used the Shadow Clone when he was at the Baisa Accord. With such a miraculous ability, even if he was at the Yan City, he did not have to personally appear, he only had to send his clone to save the person.

With Tang Yin around, things would progress even more smoothly. In terms of how he could adapt to danger, perhaps no one would be able to outdo him.

Qiu Zhen suddenly changed his mind and agreed to Tang Yin's decision to go forward, which surprised everyone.

Shangguan Yuan said calmly, "Of course I am involved in this. If Master does not bring me there, I think this trip will be dangerous. If you bring me there, there is a 90% chance of success. "

When Tang Yin heard this, he couldn't help but laugh. He liked and admired Shangguan Yuan's important point was that he knew Shangguan Yuan's character. Their characters both liked adventure, and both liked the thrill of chasing after life and death at the same time.

Without much thought, Tang Yin said, "With someone to keep me company, that would naturally be the best."

Everyone looked at each other and no longer stopped. Qiu Zhen was the number one brain under Tang Yin's command, and Shangguan Yuan was the number one general under Tang Yin's command. The two of them supported Tang Yin's decision, while the others' objections were insignificant.

After deciding to personally head over to the Yan City, on the same day, Tang Yin called Qiu Zhen and Shangguan Yuanji over, and had them temporarily take charge of the overall situation, while he himself went into the mountains to cultivate.

Tang Yin was very clear about the dangers of this trip. He felt that with his current cultivation level and skills, it was not certain if he would be able to return safely from the Yan City. He had to strengthen his own skills.

At the moment, his Fire of Darkness had only reached the first level, the Death Flame, and the spiritual energy he absorbed was not much, only 50%, but using the Shadow Clone to fight would consume a lot of spiritual energy, and without a timely replenishment, the battle would be very difficult to sustain, so he wanted to raise his own Fire of Darkness to the second level, which was also known as the Soul Combustion. The fact that the Soul Combustion could absorb 100% of the spirit energy was too important to him. Absorbing one was equivalent to absorbing two people from the past, so if he could absorb the Spirit Warrior, he would get even more spirit energy.

The realm of Fire of Darkness s was not so easy to raise. Even the Yan Lie back then had not been able to achieve this.

Suddenly hearing that he was going to train in the mountain, both Qiu Zhen and Shangguan Yuanji were startled, and subconsciously asked: "Which mountain does Master want to go to?"

Tang Yin laughed, and asked back: "Which other mountain is near the Heaven Pass?"

The location of the Heaven Pass was between two mountains, and was known as the Ten Thousand Beast Mountain. Ten Thousand Beast Mountain was a stretch of several hundred kilometers, spanning across the borders of the Feng Country. If not for the connection between the Heaven Pass, it was tantamount to cutting off the local Tianyuan County and Tianyuan County. The Ten Thousand Beast Mountain Range was high, steep, and took up a huge amount of land, and was also covered by a lush forest. Entering it, was very easy to get lost, and had always been rumored that there were ancient demon beasts lingering around the Ten Thousand Beast Mountain, and there were also many Spirit Cultivator who explored the mountain, but in the end, either no one came back, or no one found anything, and gradually no one entered the Ten Thousand Beast Mountain to investigate.

Qiu Zhen was surprised: "Master wants to enter the Ten Thousand Beast Mountain?"

"Yes!" Tang Yin did not hide anything and nodded. To cultivate the Fire of Darkness, he had to use the Fire of Darkness. Since he could not find a target to attack, he could only practice with the animals in the mountain.

Shangguan Yuanji asked anxiously: "Does Master want to go in alone?"

Tang Yin replied, and laughed: You two don't have to worry, since I was young, I have lived in the mountains, entering the deep mountains and forests is like reaching home, I will be fine.

Even though they said that, Qiu Zhen and Shangguan Yuanji still frowned, their faces full of worry.

Tang Yin continued: "When I enter the mountain this time, it will take at least five days or at most ten days. By the time I return, I will have already sent back news of Lu Fang, and will not delay the battle." After pausing for a moment, he continued faintly, "Ever since I started cultivating in the Spirit Martial Realm, I have been battling and have not taken any time out of it to engage in systematic training. I have entered the mountain this time to strengthen the skills I have learned, and also to ensure that my Yan City would not return empty-handed."

Qiu Zhen did not stop him, he only sighed and nodded, then spoke sternly: "When Master enters the mountain, you must pay attention to your own safety."

"Of course." Tang Yin squinted his eyes and laughed, then said: "During the time I'm leaving, you all must guard this secret strictly, otherwise, the warriors below might even think that I, County Magistrate, had escaped!"

Qiu Zhen and Shangguan Yuanji also laughed and nodded at the same time.

Other than Qiu Zhen and Shangguan Yuanji, no one knew about Tang Yin's plans to train in the mountain. That night, he packed his luggage, changed into casual clothes, and sneaked out of the Heaven Pass to enter Ten Thousand Beast Mountain.

Ten Thousand Beast Mountain was too big and the forest was too dense. The moment a person entered, they would be immediately submerged within the boundless sea of trees.

Tang Yin had lived in the mountain for a long time, and was extremely adaptable to the environment within the mountain. Now that he possessed Spiritual Martial Cultivation, he was like a fish in water.

As there were not many people around, there were a lot of birds and beasts in the mountain, and these groups of birds and beasts became the target of Tang Yin's Fire of Darkness s.

He walked on the mountain for an entire night. When the sky grew bright, he didn't know how far he had walked. He looked around him, and apart from the sea of trees, there were also mountains that reached into the clouds.

After walking forward a bit, his eyes suddenly lit up. In front of him was a large valley. There were no forests within the valley, just a vast expanse of green plains. The flock of sheep were leisurely nibbling on the grass within the valley.

Seeing that, Tang Yin was overjoyed, he crouched down and slowly closed in on the sheep, and when he was nearby, he extended his palm, causing the Fire of Darkness to jump. Wait a moment, he suddenly pierced through and grabbed onto a goat's neck, and with a hu sound, the goat was burnt into smoke, the other goats realized the danger and started to flee in all directions. They were running extremely fast, but not as fast as Tang Yin, and from time to time, they would use their Fire of Darkness s, and the goats who were running for their lives would turn into a faint spirit mist.

The amount of spirit qi the goat transformed into was much less than that of humans, and Tang Yin did not do it to increase his cultivation, but to train his Fire of Darkness. However, he had killed more than half of the sheep, and the Fire of Darkness was still in the realm of Burning Death.

In the end, he was tired and sat on the ground. He opened his palm and looked at the black flames that had ignited within it before letting out a long sigh.

Advancing the realm of Fire of Darkness s was much harder than raising one's cultivation. If not, Yan Lie would have long ago raised the realm of Fire of Darkness s to the second level.

After resting for a while and waiting for Tang Yin to recover enough, he stood up again and continued to walk deeper into the Ten Thousand Beast Mountain.

He stayed at Ten Thousand Beast Mountain for three days. In these three days, whenever he saw a bird or beast, regardless of its size, he would immediately rush up to them and used the Fire of Darkness s on it. Who knew how many of the birds he burned, but there were still no signs of an increase in the Fire of Darkness.

However, he didn't give up and continued to delve deeper.

On the fourth day, he miraculously ran into two people, two hunters who had entered the Ten Thousand Beast Mountain to gather herbs.

It was not easy to meet someone deep in the mountains. Tang Yin was very happy and took the initiative to greet them.

At the beginning, the two hunters were still on guard against Tang Yin, but when they started chatting, the two noticed that Tang Yin was polite, adding that he was born smiling, it made them very happy, so they gradually let their guard down.

The two hunters were both in their thirties and dark and thin. The baskets they carried on their back were filled with all kinds of rare and precious herbs, including ginseng, ganoderma, and other precious items.

The two of them asked Tang Yin: "Young man, why are you entering the Ten Thousand Beast Mountain?"

Tang Yin rolled his eyes, and laughed: "I heard that there are many ancient beasts in the Ten Thousand Beast Mountain, I want to meet them!"

"Haha —" Hearing this, the two hunters laughed and shook their heads. "That's just a rumor; magical beasts of the ancient times have long been extinct. Where would we see one now? We've been collecting herbs at Ten Thousand Beast Mountain for more than ten years, but we've never seen a single magical beast."

Although Tang Yin did not come for a magical beast, hearing his words, he was still a little disappointed. He asked: "However, many people that entered Ten Thousand Beast Mountain did not come out, and there is no lack of Spirit Cultivator among them, what's going on?"

The two hunters shrugged and said, "They must have gotten lost in the mountains. With how big Ten Thousand Beast Mountain is, and how similar the mountain looks to the mountain, this is the first time that they've gotten so close to it that they could easily faint."

"That's right!" We also ran into explorers who were just walking around a mountain. Sigh, those explorers all wish to find magical beasts and have them dream of making a fortune. I think that the real magical beasts live in their hearts. "

Tang Yin laughed, he could not tell that these two normal hunters had some philosophy behind their words.

"Young man, where are you planning to go?"

"Over this mountain." Tang Yin pointed to the big mountain in front of him and said: "Continue walking inside."

The expressions of the two hunters slightly changed. Shaking their heads, they said, "Young man, I advise you to stop here and not go further inside."

"Why?" Tang Yin looked at the two of them, puzzled.

The hunter said, "Further in, we're at the center of Ten Thousand Beast Mountain. We've never been there before, but we've often heard from the older generation. There are fierce beasts like jackals, wolves, tigers, and leopards roaming about. They're extremely vicious and can eat people without spitting out their bones."

Another hunter nodded his head, adding, "There's also a big python and a bear."

Tang Yin disagreed, and only shrugged his shoulders.

Seeing that, the two hunters asked: "What? "Young man, are you still going?"

Tang Yin said: "Wild beasts are not scary, but the truly terrifying thing are people."

The two hunters did not understand what he meant, but seeing that he was determined to go, they both shook their heads in pity, as if he would never come back.

Tang Yin looked at the herbs in their straw baskets, and laughed: "I don't have much food, I don't know if I can buy some from you two."

The two hunters asked, "Young man, what do you want to buy?"

Tang Yin rummaged through the grass basket, took out the two largest ginseng, and said: "I want these two!" As he spoke, he reached into his pocket and took out a piece of gold. He handed it to the two and asked, "Is this enough money?"

Although the two ginseng were not bad, the pharmacist would definitely not give them that much gold. Seeing this, the two hunters hurriedly took the gold and weighed it in their hands to confirm that it was real before repeatedly saying: "Enough is enough, in truth, it is not that much. Young man, you …. Pick some more! "

He was an honest man, and felt sorry for her after taking advantage of her.
