"Level 1 Lingyuan: Lingyuan 810"

"Ha ha, it's done!" Ding Longyun on the other side suddenly roared, looking very excited.

Su Li looked around and saw Ding Longyun roaring with his arms open. He knew that he had learned enough spiritual resources and evolved again.

Ding Longyun was originally a level 3 spiritual source, which evolved again and has become a more powerful level 4 spiritual source.

"Ha ha -" he waved a steel shovel in excitement and killed a rat beast rushing up from below. However, he suddenly realized that there was no message prompt from the Lingyuan he learned this time. He immediately understood that he is now a level 4 Lingyuan. The effect of this level 2 Rat beast on himself is very small. Without the effect, he needs to hunt and kill a more powerful Lingyuan beast.

"Su Li, come here quickly. These rat beasts are useless to me." Ding Longyun said and moved quickly to Xu Xuehui,.

Ding Longyun followed Xu Xuehui. Su Li relaxed and went down the stairs on the other side. Under the stairs, there are many rat beasts continuing to rush up. It is the best object he wants to obtain the source of spirit.

Similarly, only one spirit source can be obtained by killing. Killing the rat beast is much simpler than killing the high-level corpse beast. Su Li even feels that the high-level corpse beast is more difficult to deal with than the third-level sea iguana giant lizard who can obtain two spirit sources by killing himself.

For another example, if you are a level 2 spirit source, you can get a spirit source by killing a level 2 Rat beast, while Ding Longyun is a level 3 spirit source. If you kill a level 2 Rat beast, you can also get a spirit source.

It can be seen that hunting Lingyuan beast can obtain several Lingyuan, which is not absolutely proportional to the strength of the Lingyuan beast.

Now Su Li has also figured out some rules for obtaining spiritual resources. If a spiritual source kills an ordinary kind of spiritual source beast one level lower than himself or of the same level, he can obtain one spiritual source. If he kills an ordinary spiritual source beast one level higher than himself, he can obtain two spiritual sources, while killing an ordinary spiritual source beast two levels lower than himself has little effect, Almost equal to invalid.

As for the elite Lingyuan beasts, the number of Lingyuan they can obtain is different. For example, if they kill the elite Lingyuan beasts of the same level, they can obtain two Lingyuan. As for the number of Lingyuan they can obtain if they kill the elite Lingyuan beasts of a lower level or a higher level, Zurich has not encountered it, so it is not known yet.

And you can only get one Lingyuan when you kill a high-level corpse beast, which means that the level of the high-level corpse beast in the Lingyuan beast is not high, but its strength is very strong and very difficult to deal with. From this point of view, the corpse beast seems to be different from other Lingyuan beasts.

Su Li already had 18 spiritual sources, two short of the breakthrough. He exchanged positions with Ding Longyun, and two rat beasts rushed up the stairs. Without hesitation, Su Li beat out the iron rod.

The iron rod accurately hit the rat beast's head. The first rat beast rushed up was hit in the head by his iron rod and killed immediately.

A Lingyuan flew over, and Su Li calculated in his heart, "there's still one left."

The iron bar in his hand hit the second rat beast, but failed to hit the other party's head. Instead, he knocked it down the stairs.

Shadows surged behind, and more rat beasts appeared.

"It's a little abnormal tonight. There are so many monsters. It's really unexpected." Ding Longyun took a steel shovel and patted a low-level corpse beast coming down to the ground, and then handed it to Xu Xuehui. He frowned as he watched more and more low-level corpses emerge in the corridor.

What he is most afraid of now is that these low-level corpse animals will be mixed with high-level corpse animals. If he is careless, he may be caught, so he stays with Xu Xuehui and doesn't dare to be careless.

Su Li looked at the bottom of the stairs. The rat animals were still rushing up, took a deep breath, held the iron bar in both hands and waved out again.

"The last one." he recited in his heart. The iron bar successfully hit a rat's head and flew it. A Lingyuan appeared and flew to his forehead.

As this spiritual source was absorbed by him, a message immediately appeared in his mind.

"Level 2 Lingyuan: Lingyuan 2020"

"Start promotion, promotion success"

"Level 3 Lingyuan: Lingyuan 030"

"Basic enhancement: lung strengthening type I, muscle strengthening type I"

"Special skills: peeping Rune (incomplete), tooth of gluttony (left)"

Su Li took a deep breath and felt a new force pouring out of his body. With his promotion to level 3 spiritual source, his various abilities were improving, including strength, speed, five senses, five zang organs and six lungs, reaction nerves and so on.

"One of them can be selected for enhancement: strengthening lung type I, strengthening muscle type I, stomach and kidney"

Then another message emerged. Zuri had no time to think more. He beat out the iron rod in his hand, and then killed two rat beasts.

Two Lingyuan appeared, and new messages kept emerging in Su Li's mind.

"Level 3 source: source 130"

"Level 3 Lingyuan: Lingyuan 230"

Ding Longyun was promoted to a level 4 spirit source, so he could not obtain an effective spirit source by killing the rat beast, while Su Li was a level 3 spirit source, and he could still obtain an effective spirit source by killing the rat beast.

Sensing the information in his mind, for the basic strengthening choice, he chose strengthening muscle type I without hesitation.

Before, he was able to show his strength at a level lower than Ding Longyun. Su Li felt that he had strengthened his muscles, so he obtained stronger strength and speed, which was the reason why he could compete with Ding Longyun, who was a level higher than himself.

So now he chose to continue to strengthen his muscles again.

Although it is also important to strengthen other parts. For example, strengthening the lungs can make him hold his breath longer, which is conducive to fighting in the water. For example, choose to strengthen the stomach, directly drink the flood outside in the absence of clean water and food, and even eat raw meat without getting sick, Su Li still feels that the first priority now is to strengthen his muscles, To gain more power.

Only with more powerful power can we deal with more terrible monsters and survive better.

With his choice, a new message came into his mind.

"The muscle strengthening type I is strengthened to type II. It has stronger control over the muscles of the whole body and improves the fighting ability by 50%. In the muscle strengthening type II state, the strength that the whole body can exert is increased by 300 Jin."

With the change from muscle increasing type I to muscle increasing type II, Su Li felt the amazing changes in the muscles of his whole body, and his strength improved to an amazing level.

He has been promoted from level 2 to level 3, and his physical quality has been improved. For example, his vital capacity has been slightly improved, his breath holding time has been extended by about half a minute, and his basic strength has been increased by about 100 kg. For example, his original basic strength is about 600 kg. With becoming a level 3 spiritual source, The basic strength he can exert has reached at least 700 Jin.
