Ding Jingu walked down the steps of the secret passage alone, and came to a tunnel below that extended in all directions, and there were some air holes on the walls on both sides of these tunnels, some of which had earth fire gushing out, and some air holes had spring water gushing from the Hidden Sky Pool, and the scenery was quite strange.

Tunnels crisscross in all directions, forming an underground labyrinth of fire and water.

This labyrinth is full of extremely powerful mechanisms, and if you go in the wrong place, even a martial arts master will not escape death.

And more importantly, the ancestors of the Ding family made several bloodline gates in this labyrinth, which can only be opened by the people of the Ding family who drip blood into the mechanism.

Ding Jin was familiar with the road, kept moving forward in the labyrinth, pricked his fingers, connected several gates with his own blood, and finally walked into a hall.

This hall is the most important place of the Ding family, with rows of shelves placed with a large number of classics and precious medicinal materials, as well as various treasures from the outside world that have come to the Medicine King Valley to exchange pills for hundreds of years, which is dazzling and dazzling.

Ding Jingu walked to the innermost end of the hall and came to a large door.

There was no lock or handle on this door, only a prototype depression, and Ding Jingu took out an emerald green wrench from his arms, which was exactly the same as the wrench that Lin Yu had received from Doctor Ding.

Ding Jingu pressed the wrench in his hand to a depression in the door, and the wrench happened to fall into it tightly, and then he twisted the wrench, and the door let out a low humming sound, and slowly opened to both sides.

The priceless medicinal materials and treasures in this hall are all placed on the shelves at will, but the things behind this gate have to be stored separately, and only the wrench in Ding Jingu's hand can be opened, which shows the preciousness of the things behind this gate.

Ding Jingu walked into this gate for a long time before he came out of it, holding a finger-thick plant rhizome in his hand, more than a foot long, white and tender as snow.

When he was about to walk out of the main hall, Ding Jingu's face suddenly changed, and he turned his head to look at the stand on one side.

"Who dares to trespass on the forbidden land of the Ding family! Get out!"

The side of the stand was silent, and there was no movement.

Ding Jingu sneered: "If you don't come out again, when the old man makes a move, you will be asking for your own hardship!"

With the sound of slight footsteps, a thin figure turned out from behind the far stand, it was Ding Xiaotu.

Ding Xiaotu was also unlucky, originally Helian Chun handed him over to Neiying in the Dan Pavilion, and that Neiying brought Ding Xiaotu to the entrance of this underground labyrinth.

Then Ding Xiaotu walked through the labyrinth according to the map left by his grandfather, used his Ding family bloodline to open several floodgates, and finally came to this palace, and was about to find the secret book of Danzong, but he didn't expect Ding Jingu to suddenly appear.

Ding Xiaotu had no choice but to hide behind the stand in the hope of fooling the past, but the master of the Grandmaster Realm was extremely keen on the perception of the surrounding heaven and earth vitality, how could he be deceived by a child.

Ding Jingu was a little surprised when he saw that a child came out from behind the stand, especially since this child didn't seem to know martial arts at all, just an ordinary person.

"Who are you, and how did you manage to break through the labyrinth of the Forbidden Land?"

Ding Xiaotu's head was sweating, and he thought quickly in his heart, it is definitely not okay to lie completely now, he must be half-truthed, and maybe he can save his life.

"I'm fulfilling my grandfather's last wish to help him find a secret book called Danzong. ”

Ding Jingu's feet moved, and he had already come to Ding Xiaotu's approach, reached out and grabbed his right hand, and found that there was a punctured wound on it.

Ding Jingu frowned slightly, this kid used his own blood to open the floodgates, indicating that he was a descendant of the Ding family.

"Who is your grandfather?"

Ding Xiaotu didn't dare to lie: "Ding Lianzong." ”

Ding Xiaotu's grandfather is the same as Ding Lianshan and Ding Lianyu in terms of seniority, but his grade is older than that of his peers.

"Ding Lianzong!"

Ding Jingu's expression changed suddenly: "This unfilial son tried to sneak into the underground palace to steal the 10,000-year-old ancient ginseng, and was driven out of the Medicine King Valley after I caught him, are you his grandson?"

Ding Xiaotu nodded: "Grandpa gave me a map before he died, and asked me to come here to pick up a book called Danzong." ”

Ding Jingu frowned: "The Danzong is full of Dan prescriptions, Ding Lianzong has no achievements in the medical Tao without learning and no skills, how can he remember such a Dan prescription?"

Ding Xiaotu's heart was beating wildly, but his face was quite calm: "Then I don't know, grandpa said so before he died." ”

After speaking, he handed out a map: "This is the map that my grandfather left me." ”

Ding Jingu took the map and glanced at it: "Sure enough, it's the map of the underground palace!"

"This unfilial son! Back then, he secretly drew a map and sneaked into the underground palace, I relented for a while and spared his life and drove him out of the Medicine King Valley, but I didn't expect him to die and draw another one!"

Ding Jingu's heart was furious, and with a wave of his hand, the map turned into powder, and the air around him suddenly tightened, and Ding Xiaotu immediately found that he couldn't breathe, and his face instantly turned pale, and he felt suffocated.

"I ......"

Before he could say a word, Ding Xiaotu began to tremble, and he was about to faint.

Ding Jingu snorted and dispersed the vitality around him, Ding Xiaotu finally regained his ability to breathe, and hurriedly gasped.

"It's impossible for you, a kid, to sneak into the Dan Pavilion alone, who will help you?"

"The Helian family, they owe my grandfather a favor, so help with this. ”

Ding Jingu's face was full of suspicion, the Helian family is a prominent family, it is impossible to offend the Ding family for such a little thing, this child must still have something to hide, it seems that this matter is not simple, and he needs to be taken out for interrogation slowly.

"Come out with me. ”

Ding Jingu turned around and walked out of the hall, Ding Xiaotu breathed a sigh of relief, at least this little fate was temporarily saved.

Ding Jingu took Ding Xiaotu and walked outside the underground palace, and when he walked, he turned his head to see that this child really looked like Ding Lianzong back then.

"Your grandfather is dead, but what about your parents?"

"My parents died when I was born, and I have been living with my grandfather in Jinshan City on the other side of the ocean. ”

Ding Jingu frowned, it seems that this kid's life experience is also very miserable, after taking him out, he must be carefully interrogated, if there is someone behind him, it must be uprooted.

If it is clear that there is no conspiracy, then this child is young and ignorant, and he can be reintegrated into the Ding family's door.

Walking all the way, soon after arriving at the exit of the underground palace, Ding Jingu thought for a while and turned his head to look at Ding Xiaotu.

"There is an Elder Dan Pavilion waiting outside, if he sees you breaking into the underground palace, then it will be difficult to have room for maneuver in this matter. You wait here first, I'll go out and explain to him, and after I've taken him away, I'll come and take you away." ”

"This dungeon is full of deadly traps, you don't have a map at the moment, don't run around, lest you lose your life!"

After a final instruct, Ding Jingu left Ding Xiaotu in place and walked out of the underground palace alone.
