At this time, the hippopotamus monster was lying on the island in the middle of the swamp, napping and basking in the sun.

When Hong Ze reached the swamp, he found that there seemed to be some kind of formation in the swamp.

This formation can provide buffs to the Hippo Demon King, but it has no effect on people, so the Hippo Demon King will only operate within the range of this formation, and it will not attack those on the shore.

The Hippopotamus Demon King saw Hong Ze, his huge eyes blinked, and then closed them again, obviously not taking Hong Ze alone in his eyes.

The people on the shore also stared at Hong Ze nervously, to see how he wanted to deal with the Hippo Demon King.

And Hong Ze's attention is now on his system warehouse.

There are a number of props stored in the system warehouse, one of which was shaken out this morning.

Hong Ze took out the prop.

I saw that there was suddenly an extra pineapple-shaped grenade in his hand.

That's right, this is a grenade, a product that does not belong to this era, the props shaken out of the system are really strange, and when this grenade appeared, Hong Ze was also shocked.

Moreover, this grenade is not an ordinary grenade, its explosive power is 100 times that of an ordinary grenade, after all, it is produced by the system.

"This hippopotamus demon king has rough skin and thick flesh, and its defense is amazing, if you blow it up directly, I'm afraid you won't be able to kill it. ”

"If only I could throw it in its mouth......"

Hong Ze already had a countermeasure in his heart.

"Ahem!"

Hong Ze cleared his throat, then sank into the dantian, luckily in his chest, and let out a roar towards the Hippo Demon King.

"Whew-"

This roar contains all of Hong Ze's skills, just like a lion's roar.

The sound wave hit the Hippo Demon King, and the Hippo Demon King suddenly opened his eyes wide and stood up.

This is a provocation, and the Hippo Demon King is furious.

You call me and I call, see whose voice is louder, and the hippopotamus demon king opens his mouth.

"Whew-h

With this roar, the water trembled throughout the swamp.

"Whew-"

Hong Ze screamed again, this time for three seconds.

"Whew-h

Not to be outdone, the Hippopotamus Demon King screamed even louder, and the swamp suddenly had turbulent waves and a violent wind.

The people on the shore were stunned.

"What are they doing?

"I see, he wants to roar the demon king to death with his roar. ”

"Fart, I think it's almost as good as yelling at you. ”

"Why are you swearing?"

"What's wrong with scolding you? ”

......

"Whoa-oo

The demon king roared again and again, and got on the bar with Hong Ze.

Taking advantage of this opportunity, Hong Ze immediately pulled out the grenade fuse, and threw the grenade into the mouth of the Hippo Demon King with all his strength.

Due to its huge mouth, the hippopotamus demon beast could not see the front of its mouth and eyes, and the grenade rolled into the throat of the hippopotamus demon king.

Then, Hong Ze performed a light skill and quickly left the damage range of the grenade.

"Boom-"

Exploded.

This explosion is earth-shattering.

The explosion detonated from the neck of the Hippopotamus Demon King, and his head was in a different place, and his head was directly blown away, and half of his body was left, but it was also blown up.

The people on the shore were also stunned by the sudden explosion.

"Damn, what the hell is this?"

"It'...... Why did it blow up? How could it blow up?"

"What does that guy seem to have just thrown at you?"

"I know, it's a Thunderbolt. ”

"Wow, witty, it's so witty, he actually used this method, but is the 'Thunderbolt Fire Bomb' so powerful?"

"I've never seen such a powerful 'Thunderbolt Fire Bomb'. ”

......

Hong Ze returned to the corpse of the Hippo Demon King.

There are dozens of spirit crystals scattered on the ground, dazzling, and there are really a lot of spirit crystals burst out by the demon king, there were originally hundreds of spirit crystals, but many spirit crystals were blown to pieces, and some were scattered in the swamp.

Hong Ze put all the spirit crystals into the storage bag, and at the same time, he also found a red metal block in the corpse of the demon king, this metal block was irregular in shape, the size was equivalent to a pillow, and the whole body exuded a crimson light, and the weight was extremely heavy.

"Flame Red Iron, that's Flame Red Iron. ”

The people on the shore saw the red piece of iron, and their eyes burst into fiery light.

"Damn, that's really a flame red iron, he's made a fortune. ”

"Flame red iron is an important material for casting spiritual weapons. It's priceless, this thing has a very low explosion rate. ”

"Who the hell is that man, I want to know him. ”

The people on the shore were amazed, envious, and red-eyed.

Hong Ze didn't care about other people's eyes, and after putting away the flame red essence iron, he took out the city return talisman and left the secret realm.

Suddenly dark clouds filled the secret realm, the ground shook, and the secret realm began to collapse.

The secret realm is about to be reset.

Everyone also left the secret realm one after another.

"It's coming out so soon?" Su Qingbai was waiting outside the secret area, and when he saw Hong Ze coming out, he immediately stepped forward.

"Keeping you waiting. ”

"I didn't have to wait long, I haven't finished my cup of tea. Su Qingbai said with a smile, "What is the gain? With your cultivation, the ticket money will definitely be earned." ”

"It's been a reward. Hong Ze patted the storage bag on his waist, "By the way, in the sect, where can I sell spirit crystals?"

"The sect has a special place for purchasing materials, let me take you to have a look. ”

"Thank you, brother. ”

The two said and left the canyon.

The other people who had just come out of the secret realm were looking around for the person who killed the demon king with the "Thunderbolt Fire Bomb", and they all wanted to get to know him, and as for what the intentions were, only they knew about it.

However, there was no trace of Hong Ze in the four places.

"Hong Ze, I'm leaving so soon, I still want to have a drink with him. Luo Dongxu said with regret.

"I got such a precious treasure, if I don't leave, I am waiting to be robbed. Luo Donghui said.

"Well, too. ”

......

Hong Ze got a baby, which aroused the envy and jealousy of many people, but Hong Ze didn't have any waves in his heart, and this treasure didn't make him get carried away.

He pursues the improvement of strength, and money is only something outside of his body to him.

Hong Ze and Su Qingbai chatted as they walked.

"The sect has a 'material acquisition station', which specializes in purchasing materials produced in the secret realm, but the price is relatively low, only eighty percent of the market price, if you think the price is too low, you can also go to Yunyao City under Yunyao Mountain, there is a trading market, and there is an auction house, but there is a handling fee there, and the price is not much higher than that in the sect, and it takes a day to go back and forth to Yunxiao City, which will delay a lot of cultivation time, and the road is not very safe. Su Qingbai explained to Hong Ze.

As he spoke, the two of them had arrived at the material acquisition station.

Hong Ze sold all the spirit crystals, a total of more than 80, and earned nearly 7,000 taels of silver, although this money is not much, but it makes Su Qingbai impressed, ordinary people go to the secret realm, and it is already very good to be able to earn back the ticket money.

Hong Ze only sold the spirit crystal, and the flame red essence iron was relatively expensive, Hong Ze did not plan to sell it here, and would take it to the auction house for auction in the future.

"Senior Brother Su, you helped me so much today, I'll invite you to dinner,"

"Okay, then you're welcome, you've made so much money today, I'm going to have a good meal. ”

"Even though I have food, I have money. ”

The two laughed, and then walked towards Yunyao Restaurant.
