The walls on the north side are not much different from the other walls of the cave, they are all dry walls. The only difference is that this wall is covered with creeper-like branches, and the vine branches are also covered with branches and leaves.

Cheng Yifan admired that plants could grow on such a dry and hard stone wall, and the vitality was really a magical thing. The roots of the plants grew upwards at the lower part of the waterhole, which he guessed was due to the humidity near the waterhole.

Rattan covers almost the entire rock wall, and there is not a single gap in the middle except for the perimeter. Cheng Yifan observed for a long time and didn't see any clues. Curiously, he stretched out his hand, trying to pull away the vine branches. The thick vine branches clung to the rock wall, and it took him a great deal of strength to break open one of them.

The rattan was opened, revealing a few totem-like lines, Cheng Yifan didn't think about it, and continued to move the vine branches, with more and more lines, Cheng Yifan saw clearly one of the small figures, similar to rune graphics.

"Yawen, come and take a look, there are pictures and texts here." Cheng Yifan called Zhao Yawen, who was looking for clues on the other side.

After Zhao Yawen looked at the rock wall for a few seconds, he said to Cheng Yifan, "Yifan, push these rattans a little more, I want to see what is inside?"

Cheng Yifan vigorously ripped open a piece of rattan, the rattan was torn off, and a yin and yang Taiji diagram was revealed on the rock wall, like a round stone door.

There are some peculiar runes distributed around the Taiji diagram, like words, and like picture seals, "gold, wood, water, fire, earth" five fonts are clearly visible, although I can't understand which era of the font, but Cheng Yifan can vaguely guess its meaning. It is not analyzed from the glyph, but because this door is exactly the same as the shape and pattern of the broken door of the Gao family before.

"It's another five-element door." Zhao Yawen muttered in his heart.

"Yawen, this door is the same as Yunliang's?" Cheng Yifan confirmed to Zhao Yawen.

"Hmm!" Zhao Yawen nodded.

"Do you have a way to open it?" After Cheng Yifan saw Zhao Yawen's confirmation, he asked expectantly.

Zhao Yawen shook his head and said: "The principle of this Five Elements Gate is the same as the death door of the Ye family, the Jin family and the Gao family, maybe they have a way to open it, but I really don't know." ”

"Yavin, do you think this will be the exit?" Cheng Yifan asked.

Zhao Yawen shook his head again and said, "I don't know, if the layout here is the same as that of Wuyun City, then this gate should be the door of death." The location outside this gate is the same as that of the Gao family, and even if it can be opened, it is estimated that it is a passage to another place, not necessarily an exit. ”

"Don't have a cave?" Could it be that Yuan Chengzhi and Chen Qing found their food here? How did they open the door? Could this be another space?" Cheng Yifan was very curious at this time, and he also had a lot of questions, but unfortunately there was no way to open the door. I can only sigh with admiration.

"Why, do you want to go in and have a look? Headbutt it, hehe. Zhao Yawen saw through Cheng Yifan's mind and teased.

"Hahaha, forget it, let's wait and see, it's late at night, don't toss anymore, anyway, the food will be enough for a while and a half, let's sit back and wait for rescue?" Cheng Yifan glanced at his watch and said with a smile.

The fact is also the same, since entering Wuyun Mountain today, it has been a series of battles and escapes, except for being unconscious, the waking time is all in difficulty, and they haven't been able to breathe two more breaths.

Not to mention that there is no way to open this door, even if there are two of them, they may not necessarily open it, in case there is any danger inside, they can't afford to go through any turmoil.

"Yifan, can I lend your shoulder to lean?" Zhao Yawen sat next to the furnace, pointed to a vacant lot on his left and said to Cheng Yifan.

"Haha, yes, I can't sleep anyway, but I have to exchange something?" Cheng Yifan sat down, pointed to his left shoulder and said.

Zhao Yawen didn't know what Cheng Yifan was referring to, so he asked embarrassedly, "What is it?"

"Story, Zhu Yunwen's story, haha" Cheng Yifan said with a smile.

"Hey, this, what did I think it was?" When he said the second half of the sentence, Zhao Yawen lowered his voice embarrassedly. Then, he leaned his head towards Cheng Yifan generously and said with a smile: "No problem, it's a trivial matter, hehe." ”

An leaned on Cheng Yifan's shoulder, slightly relaxed, and Zhao Yawen felt very safe and comfortable. It looks like a young couple warming themselves by the fire.

With a lazy tone, Zhao Yawen began to speak: Zhu Yunwen, Emperor Jianwen, the second emperor of the Ming Dynasty, was usurped by his uncle Zhu Di after only three years of succession, known as the Battle of Jingyan.

"Three years of glory are empty in the blink of an eye, and I have no shame to the Duke surnamed Zhu;" This is what this poem should refer to.

Zhu Yuanzhang has killed countless battles in his life, and in his later years, his heart has changed greatly, and he hopes that a benevolent monarch will succeed him and help him manage the country with benevolence.

He originally wanted to pass the throne to Zhu Biao, but Zhu Biao died early, so he passed the throne to the filial and kind Zhu Yunwen.

At that time, Zhu Yuanzhang was very contradictory, because although Zhu Yunwen was kind, he did not have the courage to make a decision on the emperor's killing. Zhu Yuanzhang felt that he would rule the country and be easily usurped by the court.

He once wanted to pass the throne to Zhu Di, but Zhu Di was fierce and the fourth son, which not only did not conform to the clan rules, but also worried that he would harm his fellow clansmen after he succeeded to the throne.

So Zhu Yuanzhang finally passed the throne to Zhu Yunwen and helped him sweep away the power of the old dynasty, and Lan Yu, the king of Liang at that time, and Fu Youde were implicated in this way.

The result was also as Zhu Yuanzhang expected. After three years on the throne, he was usurped by Zhu Di, the king of Yan. Then he set himself on fire in the palace.

Back then, when Zhu Di found Zhu Yunwen's body, it had been burned beyond recognition and could not be recognized. So he always thought that Zhu Yunwen did not die but fled.

It's just that the cause of Zhu Yunwen's death in the official history is still self-immolation, and the wild history says that he escaped from the palace at a critical juncture and became a monk in Yungui.

"Fleeing into Yungui, could it be that this wild historical record is true? This cave may really be the place where Zhu Yunwen is hidden? Cheng Yifan interrupted Zhao Yawen and said.

Nodding, Zhao Yawen replied, "Nine times out of ten." ”

Cheng Yifan sighed and said: "Hey, this Zhu Yunwen is actually a poor person, I think he is just a front for Zhu Yuanzhang, and the person Zhu Yuanzhang really wants to pass on the throne is Zhu Di."

"What do you mean by that?" Zhao Yawen was intrigued by Cheng Yifan's strange thoughts and wanted to hear what unique insights he had.

Smiling, Cheng Yifan said: If Zhu Yuanzhang has the heart to pass on the throne to Zhu Yunwen, then he knows that Zhu Di is ruthless, why did he only destroy the forces of the foreign surname and leave the forces of King Yan alone? Zhu Yuanzhang must have guessed that Zhu Di would usurp the throne, and in order to block the world's best people, he would not dare to harm his fellow clansmen, this is Zhu Yuanzhang's real intention, Zhu Yunwen is actually just a victim of him. ”

"Huangkou child, such nonsense, how can it be justified, how can it be justified!" At this time, a vigorous and powerful voice sounded in Cheng Yifan's ears.

"Who, who's talking?" Cheng Yifan hurriedly got up and looked around the cave.

"What's wrong with you?" Zhao Yawen was taken aback by Cheng Yifan, who suddenly got up, and was uneasy in his heart, so he hurriedly asked.

"Yawen, did you hear a man's voice just now?" Cheng Yifan did not answer Zhao Yawen's question, but opened his mouth to ask rhetorically.

Zhao Yawen was even more nervous when Cheng Yifan asked him this. He shook his head and whispered, "No! ”

At this time, the cave was very quiet, Cheng Yifan and Zhao Yawen did not dare to speak, but listened quietly, and the atmosphere was tense to the extreme.

After a few seconds, he didn't dare to take a breath, but there was still no response. Cheng Yifan breathed a sigh of relief. I thought to myself, maybe I heard it wrong, or I was hallucinating again.

However, just as Cheng Yifan breathed a sigh of relief and wanted to sit down, another voice suddenly came: "Huangkou Xiaoer, can you actually hear me?"

Cheng Yifan could hear it clearly this time, it was a middle-aged man's voice, although the voice was not loud, it was clearly recognizable; And it can be determined that the sound came from under the pool.

"Who are you, come out for me? Otherwise, you're welcome. Cheng Yifan clenched his fists, protected Zhao Yawen behind him and shouted towards Hantan.

Zhao Yawen couldn't hear the sound and didn't know what was going on, but seeing Cheng Yifan's expression so nervous, he guessed that the two of them must have encountered danger again. Hurriedly got up and hid behind Cheng Yifan's back.

In this way, the two of them stared at Hantan motionlessly, as if they were facing a great enemy.
