The underground city is entirely built of stone, with round stone pillars supporting the roof and surrounded by stone walls, making it look vast and majestic.
Every dozen steps there is a stone basin filled with crystal stones. These crystal stones are colorful and emit light, illuminating the underground city.
"Why are crystal stones used for lighting here? Only the Tong family has the tradition of using crystal stones for lighting." Tong Bo muttered when he saw the crystal stones in the underground city.
Tong Bo's voice was very low, but Guo Zhu still heard it and said with a smile: "Maybe Yin Zhong has some connection with the Tong family."
"Brother, you are joking. The Tong family has lived in Shuiyue Cave for five hundred years. How come they are related to Yin Zhong." Tong Bo smiled gently.
Guo Zhu shook his head, "That's not possible. Think about how you entered Shuiyue Cave."
Tong Bo thought for a moment and whispered: "Maybe, let's find the innocence first."
Guo Zhu nodded and said no more, and the two began to search.
The difference is that Tong Bo is searching seriously, while Guo Zhu is pretending to search, quietly observing the environment of the underground city.
Although he knew about the existence of the underground city, he had never been to the underground city with Yin Zhong.
'I don't know if the blood python will attack me in the underground city? Guo Zhu thought, the blood python already knew Guo Zhu under the guidance of Yin Zhong, and would listen to Guo Zhu's words as long as they did not conflict with Yin Zhong's orders.
This is why Guo Zhu was able to save Zhao Yun from the blood python's mouth.
'For a while, I will try not to take action. If Tong Bo and I take action at the same time, the blood python will definitely die. This pet is quite interesting. When I return, I will try to see if I can abduct it. Guo Zhu secretly made a decision in his heart.
The underground city occupies a very large area. As big as Yujian Villa is, the underground city should be as big as it is. There are many side roads, like a maze, and you will reach a dead end as you walk. After walking for about a quarter of an hour in two days, there is still no sign. Finished.
"Second brother, eldest brother, Tongxin's eyes hurt. Come and save Tongxin."
At the same time, the childlike innocence soaked in the mercury pool by Yin Zhong was still calling for his brothers, hoping that they would come to save him, but his voice became smaller and smaller.
…
"Tong Bo, did you hear anything?" Guo Zhu vaguely heard some sounds and whispered to Tong Bo.
"What's the sound?" Tong Bo was a little confused, then he held his breath and began to listen carefully to the sounds around him.
After a moment, Tong Bo said in surprise: "It seems to be my brother's voice. Brother Guo, your ears are really sensitive."
'With more than three hundred years of magic power in my body, if my five senses are not sensitive, there will be ghosts. Guo Zhu complained in his heart, but said: "I heard the sound coming from that direction." Guo Zhu pointed his finger in the direction of the sound.
Before Guo Zhu finished speaking, Tong Bo walked forward.
The further forward you go, the clearer the sound becomes.
"It's a child's heart, it's really a child's heart." Tong Bo quickened his pace again.
After a while, the two of them saw the Mercury Pond, the center of the underground city.
Mercury Pond has two ponds, an inner one and an inner one.
The outer pool is separated by the inner pool. There are bridges on both sides to reach the middle pool. The mercury pool in the middle is a true octagonal pool. The pool is not big, about five or six square meters.
While Guo Zhu was quietly admiring the mercury pool, Tong Bo had already rushed up and saw his younger brother Tong Xin.
Tongxin was lying alone in the mercury pool, bleeding from all his orifices, and he was miserable. It was obvious that the toxin of mercury had penetrated into his body.
Tong Bo looked at his younger brother silently, with great pain in his heart, "It's all my fault, because I didn't take good care of you." '
The childlike innocence that had long been unable to open its eyes thought it was Yin Zhong coming back when he heard the footsteps, and hurriedly said: "Let me go quickly, otherwise my eldest brother and second brother will definitely teach you a lesson when they come. Let me tell you, I The eldest brother and the second brother are very good at fighting."
"What are you hesitating about?" Guo Zhu, who followed, said, "This mercury pool is highly poisonous. Come and save your brother."
When Tong Bo heard this, he felt like he was waking up from a dream. He ignored the tears on his face and jumped into the air. He somersaulted over the mercury pool, grabbed the child's heart soaked in the mercury pool, and pulled the child's heart out of the mercury pool. come out.
Tong Xin, who was rescued, lay in Tong Bo's arms and shouted: "Don't touch me, my eldest brother and second brother will come to save me in a moment."
Tong Bo gently wiped away the blood from the corners of Tong Xin's eyes, his voice choked with sobs, "Don't be afraid, Tong Xin, big brother is here."
"Big brother, big brother, you are finally here, you are finally here to save Tong Xin." Tong Xin hugged Tong Bo and shouted happily, "Where is second brother, is second brother here? Second brother, don't scold me, I was wrong. "Speaking of this, the expression on the childlike face turned to fear and grievance.
"Don't be afraid, the second brother is not here. The ones with the eldest brother are his friends." Tong Bo comforted Tong Xin with gentle words.
Hiss... hiss... hiss hiss hiss hiss
"Brother, hurry up!" Tong Xin suddenly pushed Tong Bo away, "There is a big snake here, it's very scary. Brother, hurry up."
"What kind of snake is there? Tongxin, what nonsense are you talking about?" Tong Bo looked around and found nothing.
Just as Tong Bo was about to help Tong Xin up, he saw Guo Zhu's serious expression and couldn't help but ask: "What's wrong?"
"Your brother is probably right. There is indeed a giant python in Yujian Villa. On the day of the throne passing ceremony, many people in the world saw it." Guo Zhu made a warning gesture.
Tong Bo heard this and said to Tong Xin: "Tong Xin, you lie down obediently. My elder brother will take you away after killing the big snake." He then put Tong Xin's body flat.
Then he said to Guo Zhu: "Brother Guo, if there are any enemies, please ask Brother Guo to protect my younger brother."
"Wouldn't it be more certain if we attack together?" Guo Zhu asked tentatively.
Tong Bo shook his head, "I'm here to save my brother, that's what's important. Besides, it's a great favor for Brother Guo to accompany me to this Dragon Pond and Tiger's Den..."
"Okay, stop talking. If you say anything else, you'll be out of sight. I will help you protect your brother." Guo Zhu reached out and interrupted Tong Bo.
As soon as the two of them finished talking, the hairs on Tong Bo's body stood up, and he felt danger.
This feeling is his intuition from practicing martial arts for many years.
He slowly turned around and saw a huge creature.
A giant python stood upright and looked down at them.
The giant python has indifferent eyes, spitting out words, and is ready to go.
Suddenly, the giant python launched an attack, its body moved downwards rapidly, and it opened its bloody mouth and rushed toward Tong Bo.
Tong Bo shouted: "Brother Guo, be careful, protect my brother." Then he jumped up and avoided the python's attack.
Guo Zhu had magical powers and discovered the blood python earlier than Tong Bo, but he felt that the blood python had no ill intentions towards him.
He knew that the target of the blood python was Tong Bo.
When Tong Bo told him to be careful, he quickly stepped forward and took away Tong Xin.
Guo Zhu put his childish heart on the stone wall and turned back to watch the confrontation between Tong Bo and the blood python.
