The Witcher: Son of the Planes.

The successful refining of the manganese heart potion gave Colin a new point for the growth of his mental power, but the specific effect would only be known after taking it.

After everything was ready, Colin prepared to start taking the manganese heart potion in the training room. Before taking it, he naturally needed to carefully monitor and record the effects on Earth.

Colin originally thought that the manganese heart potion was very unpalatable, but he didn't expect it to have a refreshing taste when it entered his mouth. Before he could even taste anything else, he had already swallowed the entire tube of potion.

The manganese heart potion was not as strong as the mental power potion, and the reaction after entering Colin's body was not strong either. However, the monitoring from Earth told Colin that it had taken effect. Colin's mental power continued to rise slowly, and it lasted for about a whole day before the effect of the manganese heart potion ended.

Comparing before and after, his mental strength increased by 2 points, which may not seem like much, but Colin's average annual increase in recent years was only 0.1, which is equivalent to the effect of nearly 20 years of hard training.

Colin calmed down and told his wives about the effects of the manganese heart potion. It could be used as a family secret recipe, and the most important thing was that the side effects were extremely mild.

After resting for a day, Colin took the manganese heart potion again. It still took a whole day to digest and absorb it, but the increase in his mental strength was only 1.6. However, this number still made Colin very happy because the decrease was not much.

Over the next period of time, Colin took manganese heart potion repeatedly, and the value that increased each time kept decreasing. The subsequent nine data were: 1.3, 1, 0.8, 0.6, 0.5, 0.4, 0.3, 0.2, 0.1. The last increase in value was the same as the annual asceticism, so Colin stopped taking it.

I took 11 bottles of medicine and increased my mental strength by 8.8, but it only took less than a month. It was worth it, absolutely worth it. It can be used as a key medicine for family members to break through.

While Colin was happy, Earth also detected a slight abnormality. That is, the value of Colin's unknown bloodline changed, and it actually increased by 0.1. This made Colin a little puzzled. He couldn't figure out what the specific side effects of this medicine were. But after repeated monitoring by Earth, it said that Colin was in good physical condition and there were no other abnormalities. Colin didn't think about it any more.

After taking drugs for a month, Colin's mental power has reached over 50 points, which is not far from the critical point of 60 points for a second-level wizard. He will hopefully be ready for promotion within a few decades.

Colin didn't want to tell anyone outside the family about this potion for the time being. For a moment, Colin even had the idea of ​​returning to the underground world and killing Oude. However, considering the request of his teacher Lina, he could only hope that Oude would not be able to find an item to exchange for a while, or that Oude would not be able to find it in the future.

The surge in Colin's mental strength over the past month made him seem even more oppressive. Some servants in the mansion didn't even dare to get too close to Colin. Some servants who accidentally approached Colin even fainted after seeing his eyes.

Colin knew that this was the sequelae of the short-term surge in mental power. In the following period of time, Colin patiently digested the gains of this time in the training room. It was not until three months later that Colin was able to control it freely.

The Heaton family has become increasingly busy recently. After stabilizing his mental strength, Colin went to visit Lina again. He learned from Lina that a new round of plane wars was about to begin, but this time they would no longer fight alone, but would follow the Black Mamba Warlock Family as a guest army.

The latest batch of space fortresses delivered for use have been distributed to major forces one after another. All major forces are doing the final debugging. It is believed that after proficient use, they will surely provoke a new round of plane wars. The Black Mamba Warlock Family is also the first family to obtain the space fortress this time. As for the space fortress of the Heaton Family, Lina is not sure how long she has to wait.

The Black Mamba Warlock Family is considered to be the top existence in the entire warlock group. Although there are no demigod warlocks, several old guys in the family have reached level three and are not someone to be trifled with.

After listening to Lina's narration, Colin finally understood that this time they would use the space fortress directly for combat. Even the identity of the guest army was something Lina had fought for with great difficulty. This was a way to get a piece of the pie while also allowing her to familiarize herself with the combat methods of the space fortress, killing two birds with one stone.

The second-level fire element energy core potion that Colin asked Lina to make last time has been completed. Just as Colin came, Lina handed it to him directly. However, now is not the time to take it, so he can only wait for a while before taking it.

Colin didn't want to reveal the secret recipe of manganese heart potion for the time being, but the blood of the abyss demon in the underground world could be given as a gift. After giving a few bottles to teacher Lina, Lina was also very interested. She had been to the underground world when she was traveling before, but after missing the riot of the abyss demons, she never went there again.

She was also very interested in the bloodline of the abyss demon, but as she was about to go on the expedition, after accepting the gift from her apprentice, she could only study it later when she had time.

After Lina's return, the years she has been in charge of the Heaton family have shown great vitality, like the boss of the city of Megwen. In particular, the Heaton family has completely absorbed the output of the acacia trees for more than a decade, making the Heaton family rich in Megwen City, and naturally the preparations before the war have become more sufficient.

In addition to the slave warriors produced by the Chilan plane, there are also goblin slaves from the Robinia plane. Although their strength is lower, they can still be used as cannon fodder. Of course, in addition to these slave creatures from their own planes, they also purchased hundreds of thousands of slave creatures from other forces.

Although a contract was signed with the Black Mamba Warlock Family, the customary rules outside the contract were very simple: whoever paid more would gain more. In order to earn more profits, the Heaton Family also tried their best.

Colin's wives were still making final preparations, buying the supplies they needed from various channels and refining commonly used potions. This time, except for Nora, the three of them would accompany Colin to the battle. Jenny from the Agri plane would stay to take care of Nora, and Barrick, as Colin's half-disciple, would naturally also go to the battle.

Speaking of Barrick, he does have some talent. Although he is a half-orc, he has made rapid progress with Conrad's guidance during the days when Colin was away. After more than ten years, he has reached the quasi-level strength. The iron rod in his hand is no longer the one Colin gave him, but a metal rod rich in various alloys. This is because there is no one in Colin's family who studies formations, otherwise the power of the alloy rod would definitely be even higher.

Two months passed before Colin received another notice from Lina, asking him to be ready and set off in three days.

Three days passed quickly. Colin and his three wives said goodbye to Nora and followed teacher Lina's family members on a floating airship to the space port.
