Although there are many opportunities in the Lava Land, there are actually not many adventurers who come to this place to try their luck. The mutated creatures in the Lava Land are all about level 20, and some can even reach level 24 or 5. Therefore, if you want to come to this place, the level of adventurers must be at level 18 or 19 at the most.

Although there are quite a lot of adventurers at level 18 and 19, most of them have been won over by some decent forces. Adventurers with backstage do not need to do too much effort in material needs. For example, those adventurers who join a large family want to make money, they can get rewards by helping the family do something, and there is no need to venture into the lava land.

As for the remaining level 17 and 8 adventurers, most of them have become the brains of mercenaries of the size of the stinger. They can also obtain money by plundering their mercenaries. Therefore, few people will hunt mutant creatures in harsh places such as Lava Land because of money. For example, Wu Song last entered the Lava Land and wandered around for half a day, and the number of adventurers he saw could be counted with one hand.

"tnnd, how good it would be if it were summer." Wu Song walked and cursed as he walked. Along the way, he killed a lot of mutated creatures, but the adventurer did not see any of them.

Winter is the best season for adventurers to hunt mutant creatures. Due to the cold, many mutant creatures will choose to hide in caves. At this time, the danger coefficient in the wilderness is the smallest. After the weather warms up, the mutant creatures will frequently move out, and even form a large-scale tide of insects. This is a fatal threat to adventurers. Therefore, many adventurers will choose to hunt mutant creatures for life in winter to make money, save enough money for a year of survival, and then do what they can when they encounter large beast tide insects, and many adventurers will not even leave the city gate for a month or two. At this time, everyone is busy hunting mutant creatures that are easier to kill in the wild to make money, so basically no one will come to the lava land to make trouble. In summer, due to the flood of mutant creatures in the wild, some people will choose to go to the lava land to try their luck in order to avoid insects.

Since no one helped to clean up the mutant creatures, Wu Song almost relied on himself to clean up while moving forward, so his speed would not be too fast. However, after learning the Spirit Transmission Art, he added a batch of high-quality potions to the Alchemy City. Although Wu Song walked very slowly, his minimum safety was guaranteed. After about a whole day, Wu Song walked to the nucleus area. He wandered around the nucleus area for half an hour, and finally found a heart of earth fire on a hillside!

After all the torture, Wu Song now saw the Heart of Earth Fire than the Widow. Seeing that there were no mutant creatures near the hillside, he ran straight to the Heart of Earth Fire. But when he got up the hillside, the auxiliary device suddenly issued a very strange reminder, "There are powerful organisms around you, please be careful."

"Magic organism?" Wu Song was shocked after hearing this. He climbed down from the hillside without any hesitation.

Danger prompt sound is another major function of the auxiliary device. This function plays an alarm. When a powerful target that the auxiliary device can detect within 50 meters around Wu Song appears, the auxiliary device will issue an alarm on its own. The main types of organisms that can make the auxiliary device emit alarms are two major types of organisms. One is a non-human life form that is ten levels higher than Wu Song's level, and the other is a non-human life form above the leader.

Wu Song is now at level 20. If the alarm is triggered at level, then the level must be at least level 30. The mutated creatures in the Lava Land are at most only level 24 or 5. Therefore, the moment the alarm sounded, Wu Song realized what he had encountered.

"Shuangfan Fire Dragon?" Wu Song frowned, then began to circle around the hillside from a distance, making him give up the Earth Fire Heart that he had finally found. However, if he wanted to pick Earth Fire Heart, Wu Song had to determine where the Double Sail Fire Dragon was. With Wu Song's current strength, even if he was taking drugs, he wanted to fight a Double Sail Fire Dragon alone. Once he was entangled by the Double Sail Fire Dragon, even if he could not hide, it would be a problem to kill, let alone escape. Therefore, Wu Song must first confirm whether his picking Earth Fire Heart will attract the attention of this Double Sail Fire Dragon.

In a sense, luck is an important factor for adventurers to complete tasks in the wild. This time Wu Song was very lucky. He walked around the other side of the hill and found a large cave behind a relatively hidden rock. The Shuangfan Fire Dragon was lying inside the cave. Fortunately, the big guy was sleeping.

Although the Shuangfan Fire Dragon is not as good as the giant dragon in terms of ability, this thing is also considered a side branch of the giant dragon. The fire dragons on both sides also have some similar habits to the giant dragon. For example, in terms of lethargy, the Shuangfan Fire Dragon with a long life is no less than the giant dragon. Most of the Shuangfan Fire Dragons are used to sleeping beautifully after eating, and the sleep period is a few days, and it can last for several months.

It was obviously a good time to pick when the Shuangfan Fire Dragon was sleeping. Wu Song went around without hesitation and tiptoed to the top of the mountain to get the heart of earth fire. However, after the picking, Wu Song did not leave directly, but took the risk to return to the Shuangfan Fire Dragon Cave again and used an auxiliary device to investigate the properties of the Shuangfan Fire Dragon.

Shuangfan Fire Dragon (animal system, small boss), level: 25, attack: 1388-1726, defense: 587-722, Qi and Blood: 159000, water attack damage increased by 50%, fire attack damage was all converted into its own Qi and Blood, and poison attack damage was reduced by half.
