Just because of his clear mind, Xu Dong thought that there might be some substances in this cave that could ripen plants.

Plants need water, soil, sunlight, and water to grow, and he thought of watering that corn.

He took a clay pot and scooped water from the pool and poured it on the corn stalks, and the leaves of the corn were indeed much greener, and the jade cobs were also expanding.

He took the hot water from the splash and poured it into the dirt at the mouth of the cave, and with a "bang!" sound, the plants instantly turned scorched.

Seeing the death of the corn, Xu Dong was sad, this corn was his only food, and now his way of life was broken.

He blamed himself for being in a hurry and doing a stupid thing to promote the seedlings, as the saying goes, "you can't eat hot porridge in a hurry", this is the truth!

Suddenly, he saw three ripe jade cobs hanging from the scorched corn stalks, revealing the yellow grains of rice inside.

Xu Dong broke off the three jade sticks and held them in his arms as a heart and liver baby.

In the process, several grains of corn are scattered to the ground, and those corn kernels take root, and in an instant they grow into green seedlings as tall as a foot.

Some of the herb seeds he had fallen upon were also reborn in the soil, and in a short time they were lush and green.

Witnessing this miracle, Xu Dong was stunned and rejoiced, it seems that this Bigu Lotus Cave really has many resources to enjoy.

Xu Dong pulled out the scorched corn stalks, came to the stone hall, found a fire extractor to set the corn stalks on fire, and then roasted the corn on the flame.

A fragrant aroma was overflowing, the corn was cooked, and eating roasted corn at this time was a pleasure for Xu Dong.

After all, it is Linggu, after gnawing on the three jade sticks, he has stored a lot of energy in his body, even if he doesn't eat food for two days, he won't feel hungry.

Xu Dong used the mental method he learned in Linggumen to carry out a small Zhoutian cycle in his body.

The so-called Xiao Zhou Tian cycle is to let the spiritual power in the dantian flow out, enter the meridians, and run around the body in the eight veins of the Qi Sutra.

After doing a small Zhou Tian cycle, Xu Dong felt a little tired, he jumped into the steaming pool and used the spiritual water in the pool to restore himself.

He hurried down into the deep water, the polyps trailing him, and when he looked back, he looked like he had a red tail.

The polyps sucked the tiredness out of his body, making him energetic and wading through deep waters.

He reached the middle of the pool, the deepest part of the pool, and the water was almost flooding his jaw, and he could only stand on tiptoe.

Suddenly, his toes touched something, round and slippery, like an extra-large bead.

It turned out that this thing was a mechanism, and it had been touched by his toes, and with a "boom!" sound, and the stone wall suddenly opened a door.

Inside the door was a stone chamber, and he hurriedly ran up from the pool, and without even having time to put on his clothes, he stepped into the stone chamber.

As soon as he entered the stone chamber, the door of the chamber closed silently, and the chamber was empty, and there was nothing.

The space of the stone chamber is very small, and the air inside is getting thinner and thinner, and if you don't get out in time, people will suffocate in the stone chamber.

Xu Dong was in a hurry to find the mechanism of the stone room, which was made of several large stone slabs, and there were no mechanism buttons on the stone slabs at all.

He used his hands to dig at the crack in the stone, trying to move the slab away with his own strength.

At this moment, a flame erupted from the crack in the stone, and the fire was whirring, and Xu Dong hurriedly retracted his hand.

From this point of fire, it was like lighting a fuse, and the flames "squeaked" away, and in the blink of an eye, flames erupted from every crack in the stone.

"It's over, I, Xu Dong, will rest for the rest of my life, and I'm going to be burned to death in the stone room!"

Thousands of tongues of fire enveloped Xu Dong in it, and the firepower became more and more fierce, and this small stone room seemed to have become a crematorium in an instant.

The heat continued to rise, Xu Dong felt that his blood vessels were about to burst, his heart couldn't bear the pressure and was about to jump out of his chest, and his skin and flesh also emitted a burnt smell.

He simply closed his eyes, only hoping that this catastrophe would come sooner, and that it would be impossible to escape death anyway, so it was better to get out of the sea of suffering as soon as possible.

"Tom!"

I don't know how long later, there was a thunderous explosion, and a crack opened in the inner wall of the stone chamber, revealing another stone chamber inside.

Xu Dong drilled through the crack and arrived at the stone room inside, where a fresh breeze blew out of the crack in the stone, making him feel refreshed.

He sensed that something was wrong again, because the wind was getting colder and colder, and there were still droplets of water in the wind, and the temperature in the stone chamber quickly dropped to zero.

A layer of hoarfrost rose on the stone slab, and in a blink of an eye, it turned from frost to ice, and ice shoots more than a foot long came out, hard and sharp like a sword.

Xu Dong shivered all over, and his body hugged tightly.

He experienced both ice and fire in a short period of time.

After about half an hour, another door opened, and there was a large stone chamber with a scarlet carpet on the floor.

In the center of the stone room, an old man in a Taoist robe sits on a futon, holding a book in both hands.

Xu Dong was ecstatic, thinking that as long as he crossed this threshold and entered the stone room, he could worship the old man with immortal wind and bones as a teacher.

The internal conditions of cultivation, that is, the innate things of the practitioner: the dantian, the spiritual root, and the godhead......

The external conditions are the dojo, the sect, the teacher, etc., and a good dojo is more intense than the aura gathered elsewhere.

A good sect, tens of thousands of years of accumulated cultivation vitality, and the accumulated experience of your ancestors can allow you to take some shortcuts.

A good teacher guides you to rise step by step, which is also one of the elements of external factors.

At present, Xu Dong is in urgent need of a master to give guidance.

"Master, please bow down to the little apprentice!"

"Plop!"

Xu Dong was anxious to step in to apprentice, but unexpectedly, his toes tripped over the threshold stone, and he fell hard, falling him like a dog gnawing mud.

Before he could get up from the ground, something cold and cold wrapped around him, and when he saw that it was the tail of a large snake, he screamed in fright.

"Master, save me!"

He was full of hope that the old man would come to his rescue, but the old man remained indifferent, as if he had not seen him, and still read the fairy book.

Xu Dong had no choice but to save himself, he pinched the seven inches of the snake, and when he was entangled by the snake, he was able to pinch the seven inches of the snake.

Another snake seemed to fall from the roof of the stone chamber and landed on him.

And some snakes came out of nowhere and got caught up with him.

For a moment, Xu Dong's body was entangled in snakes, and he was wrapped in the middle like a meat filling, making him breathless.

Fortunately, his heart was still clear, and he had an idea, and he used all his strength to roll towards the ice room, and those ice blades and ice swords pierced into the snake's body.

In a short time, hundreds of snake corpses were scattered, and these snake corpses were piled up on the ground, filling most of the ice room.

At this moment, the door of the fire chamber opened, and Xu Dong threw the snake corpses into the fire chamber.

The fire chamber was like a furnace, and as soon as the snake corpse was placed, the heavy stone door was closed again.
