The two of them fought and retreated. Fortunately, after the bat boss got ten fireballs, he did not chase the two of them anymore, but returned to the place where it had been hung before to rest.

It seems that it loses its fighting will after its health drops to a certain value and needs to go back and rest.

Jin Ke and Zhang Mengdi also hurried back to the ground to replenish their energy, find some food to eat, and then go down to continue fighting.

While Zhang Mengdi was fighting, Jin Ke explored around the hall where the bat boss was, but found a locked door, and was energized with an energy ban, and only a specific key could be opened.

It seems that if you want to continue to pass the level, you must kill the bat boss and get the key from it.

Two hours later.

Jin Ke felt that it was wrong.

This is indeed very wrong.

The blood volume of ordinary bats is not high, and the blood volume of this bat boss is not high either.

Judging from the 50,000 damage points exploded above its head, its basic defense is very low, and Zhang Mengdi's fireball technique consumes all 50,000 damage.

Even if it is like the giant evil rhinoceros, it has 5 million blood, and because it consumes all the damage, 100 fireballs can end it.

But it had already eaten Zhang Mengdi and bombarded the fireball hundreds of times, but it was nothing.

This is unscientific.

After careful study, Jin Ke quickly came to a conclusion.

That's where the bat boss is hanging is problematic.

Just like the spring water on the tour, the bat boss can quickly fill up after hanging there, so no matter how many fireballs Zhang Mengdi threw over, it can restore the blood to full value during the two of them going back to replenish their energy.

Jin Ke asked Zhang Mengdi to bombard the bat's hanging with a fireball, but it didn't work.

If you observe carefully, you will find that there is a black mist looming in the place where the bat boss is hanging. It feels like a small space-time crack. Some kind of energy escaped from the space-time crack can treat the bat boss.

If this continues, it will be useless for him and Zhang Mengdi to be busy for a long time.

This definitely won't work.

After returning to the courtyard again, Jin Ke went to the pharmacy shop.

All the phantom bottles displayed here are black and round and look very much like grenades.

The cheapest potion is 10 gold coins, the most expensive ones are 20 gold coins, 50 gold coins, and 100 gold coins.

There are no more expensive ones.

But the cheapest one is only sold for 1 gold coin.

The one that sells only 1 gold coin... is an empty bottle.

A transparent round crystal bottle with a lid.

"Even empty bottles have to sell 1 gold coin, so I'm drunk!" Jin Ke was powerless to complain.

The other potions were all black, and they should be round empty potion bottles filled with black potions.

All the potions are black and match the style of these shops.

Black shop.

A bottle of potion caught Jin Ke's attention.

The name of this bottle of potion is "Fengmai Ling".

"Mai Feng Ling: Close the target's bloodline so that it cannot recover his blood."

"Duration: 60 seconds."

"How to use: Throw at the target, bring your own power, and you can automatically lock the target within 20 meters for jet attack."

"Hand throw automatic tracking short-range missiles? The things sold in Nightmare Castle are indeed different." Jin Ke complained a few times.

Jin Ke thought that when the bat boss flew back to the top of the cave and hung it, he would be unable to recover his blood as long as he threw a bottle on it. At this time, Zhang Mengdi followed up and threw a few more fireballs, and he should be able to get it done.

The problem is, 10 gold coins!

Are you mistaken? So far, Jin Ke has only collected less than two gold coins in total. What year and month does 10 gold coins need to kill monsters?

Even if the energy core can sell another gold coin, it is far from enough to 10 gold coins.

But in this situation, if you don’t get this vein spirit, you feel that you can’t handle the bat boss.

If you want to get the Fengmai Ling, you have to go outside to get gold coins first.

The evil rhinoceros outside will be resurrected, and there are also many pythons. Killing them can collect a lot of evil rhinoceros and python meat. You can get it in the food store to exchange for different amounts of copper coins.

That would be a very long process!

Jin Ke had a solution to get gold coins quickly.

But he was hesitant.

This method is... the black-mounted bow and arrow in his hand is worth ten gold coins and can be recycled at a price of 2.5 gold coins in the weapon store.

The entire set of black armor on him is worth thirty gold coins and can be recycled at the armor store for 7.5 gold coins.

In this way, he happened to have ten gold coins and could buy a bottle of Fengmai Ling.

With the Fengmai Ling, Zhang Mengdi could kill the bat boss and get the key from the bat boss's corpse. There should be a fragment of a round carving.

The guide to Nightmare Castle should be able to continue.

I'm afraid... if I buy a bottle of Fengmai Ling, but still can't get the bat boss, Jin Ke will be in tears by then.

Should we sell the black bows and arrows and armor to exchange for the sealed meridian spirit?

This was a really tough decision.

Jin Ke came to the weapon store and placed the black bow and arrow on the round table, wanting to try out what price the owner would recycle.

He just tried it and didn't decide to sell the black bow and arrow.

The shop owner reached out to fish under the table and fished it... It was pitch black below him and couldn't see anything, but he still took out a few gold coins and put them on the table, and pushed the table over toward it.

There are actually five gold coins?

There are times when the black-hearted shop owners make the wrong calculations? Isn’t it a quarter of the price recycle?

Soon Jin Ke understood what was going on.

Jin Ke did not take away the gold coins, but turned the round table back.

Although the shop owner here is inhumane, does not speak or bargain, as long as Jin Ke doesn't take away the gold coins, they will not take away his goods privately, which is very reassuring.

Jin Ke took out the chip that increased the critical strike rate from the slot where the black bow and arrow was installed and placed it alone on the round table.

Sure enough, the shop owner took two gold coins and 50 silver coins from under the round table and put them on the table, then pushed the table over.

The value of a chip is 2.5 gold coins!

And the owner of the weapon store acquired these chips!

Jin Ke remembers that there are three chips in this armor set on his body!

Although these chips are also very important and even more difficult to get than equipment, under this situation, Jin Ke had to bear the pain of giving up his love if he wanted to continue to attack the Nightmare Castle.

I can't bear to leave my child and can't trap a wolf!

What does it mean to be reluctant to let your child go to trap a wolf? This is definitely not what a parent said. Who threw the child out to trap a wolf?

Are they shoes?

But now Jin Ke does feel like he has given up his child to trap a wolf.
Chapter completed!
