Su Chen picked the monster that just looked fierce and took it directly back to the top of the mountain.


    He plans to take these ten monsters to test the pet synthesis function.


    First of all, we must subdue these ten monsters into pets.


    This is not a problem for Su Chen. After all, it is easy to subdue these monsters with Su Chen''s Alchemy.


    In the blink of an eye, ten monsters crept at Su Chen''s feet.


    Su Chen immediately opened the pet interface and opened the synthesis system.


    Synthesis requires two pets without any specific requirements. However, according to the system introduction, if the level, lineage, five elements and other attributes of the two pets are closer, the success rate of synthesis will be higher. If the difference between the two pets is too large, the synthesis rate will be very low, but the probability of variation during synthesis will increase.


    In short, each has its own advantages.


    If you want to synthesize a powerful pet step by step, you''d better choose the same kind of monster to synthesize.


    If you want to touch the probability variation, find different kinds of monsters to synthesize.


    In addition, it is worth mentioning that no matter how you synthesize, there is a probability of failure. Once the synthesis fails, the one with weak strength among the two pets will directly die and disappear, and the one who survives will also suffer certain damage. You can continue the synthesis only after you recover the injury.


    There are five porcupines, three vipers and two lizards among the ten monster beasts brought by Su Chen. Their strength is in the lunhai territory. They basically have no intelligence, but are better than beasts.


    In fact, it''s a beast, because the aura of Lingshan is too strong. Even the most ordinary beast, living at the foot of Lingshan for a long time, will improve by leaps and bounds.


    Most of the monsters that can be seen in Lingshan are in lunhai, and some of them can even break through to heaven.


    Su Chen first chose the two lizards for synthesis.


    Gently click the synthesis button. In an instant, two strange lights enveloped the two lizards, and the two lights gradually merged into one. The process lasted only two or three seconds, followed by a system prompt.


    "Ding, congratulations to the host for successfully synthesizing the new pet ''tough lizard''."


    "Tough lizard: combat effectiveness 108, defense increased."


    After the pet system is upgraded, there is a judgment standard for pets, which shows intuitive strength according to combat effectiveness.


    Before the synthesis, the combat effectiveness of the two lizards was very low, less than 80 points.


    At present, Su Chen''s strongest pet is the newly summoned haotianjing erha, with a combat effectiveness of more than 56000.


    Once synthesized, two lizards become one, and the combat effectiveness increases by about 40%


    Su Chen thought about it and felt that the synthetic system was still in great trouble.


    Su Chen synthesized two porcupines and got a sharp thorn porcupine. The thorn became longer and more, and the combat effectiveness increased by almost 40%


    Another two vipers were tested, but the result was bad luck. The synthesis failed and one Viper disappeared.


    There was only one Viper left. Su Chen pondered for a moment and synthesized the sharp thorn porcupine and viper.


    "Ding, synthesis failed."


    The spike porcupine looked very depressed, and the Viper disappeared directly.


    Su Chen shook her head. There was a big difference in the types of pets. It was really easy to fail.


    Su Chen didn''t need to keep the remaining pets. She just synthesized them one by one.


    "Ding, synthesis failed."


    "Ding, synthesis failed."


    "Ding, congratulations on the new pet ''haolizard''"


    I didn''t expect that porcupine and lizard were successfully synthesized for the last time.


    Although not a mutant pet, it has formed a new species.


    A lizard covered with spikes.


    But this thing... Doesn''t coordinate in any way. It''s not the product of natural evolution at all.


    However, the combat effectiveness has unexpectedly increased a lot, reaching 247, which has fully tripled!


    Su Chen probably knows the urine of the synthetic system.


    If you want to get powerful pets, you still have to synthesize them with different kinds of pets. Although the probability of failure is very high, as long as you succeed, your combat effectiveness will increase greatly.


    Su Chen suddenly had an idea.


    Would you like to experiment with erha?


    Anyway, erha''s combat effectiveness is strong enough. As long as we experiment with monsters whose combat effectiveness is not as good as erha''s, even if the synthesis fails, the loss is only monsters with low combat effectiveness. Erha is injured at most, becomes depressed for a period of time, and recovers after a few days of rest.


    But what is used to synthesize with erha?


    "Huang..."


    Su Chen was about to call someone when she suddenly remembered something and picked up a jade pendant to give a voice to Huang Xi.


    A moment later, Huang Xi stepped on the void and appeared in front of Su Chen.


    She said weakly, "say something."


    She is used to being called by Su Chen.


    "Is there any place near Lingshan where there are many monsters? It''s best to have a large number of monsters in Haotian territory."


    "The monster of Haotian realm?"


    Huang Xi thought and said, "there must be spirit beast peak, but the spirit beast peak of this level will not be lent out."


    "What if you pay for it?"


    "That''s OK. The spirit beast peak raises monsters mainly for sale, but the price is not cheap. Even the most common monster in haotianjing sells more than trillion spirit stones."


    It''s really not cheap, but it didn''t exceed Su Chen''s expectation. After all, it''s a monster in Haotian realm. Many sects don''t even have an expert in Haotian realm.


    Su Chen now has 100 billion spirit stones to use. It''s no problem to buy ten monsters in Haotian territory.


    Moreover, Su Chen''s treasures are like clouds. If they are all replaced by spirit stones, he can afford to buy dozens of hundreds of haotianjing monsters.


    However, considering the failure rate of synthesis, Su Chen feels that if she buys monster synthesis, her wealth will soon be drained, which is not suitable.


    If you can synthesize powerful pets, it''s pretty good, but if you fail, you''ll lose your money.


    "Except spirit beast peak?"


    Huang Xi thought and said: "There are three secret places in Lingshan. One of them is called ''Tongtian tower'', which was built by Yu Tianheng in those years and has been preserved. In the Tongtian tower, a large number of ancient fierce animals are imprisoned, including the great demons in Haotian and even Qitian. However, these great demons are extremely powerful and difficult to defeat, and it is even more difficult to subdue. I once challenged Tongtian tower , I fought with an ancient demon in Haotian territory. It took nine cattle and two tigers to kill him. I was also seriously injured. "


    Sky Tower?


    The name Su Chen is no stranger. There is the Tongtian tower on Taigu island in Xuanyuan continent.


    But this is also normal. After all, the Tongtian tower in Xuanyuan continent was also built by yutianheng.


    Moreover, the secret place of Tongtian tower in Lingshan may be the real Tongtian tower, and others are imitated.


    Su Chen immediately made up her mind: "I''m going to Tongtian tower and lead the way."


    "Are you sure? In that place, only friars who seek to break through opportunities will challenge. Generally, few people will take risks."


    "Sure." Su Chen said firmly.


    At the right time, he can also take this opportunity to temper his combat effectiveness.
