Inside Qin's dormitory.

  Li Feng immediately took out 2,000 yuan from the wallet and put it in his own pocket, then hid the entire wallet under the quilt.

  At this time, it has been five or six hours since the previous departure from the old nest. The three-headed and three-tailed ant king, with 300 soldier ants, have been busy rushing about during this period, and have already caught a large pile of various insects.

  Spiders, grasshoppers, earthworms, caterpillars, green vegetables, everything is here!

  It seems that the three ant kings did not personally take action, otherwise, relying solely on soldier ants, it is estimated that they would not be able to bring back spider and grasshopper prey of this size. Li Feng's heart was slightly excited as he processed all the prey one by one.

  "My god, 176 units of blood essence, it's more than I imagined." Li Feng exclaimed.

  Adding the 33 units of blood essence left over from before, that means he now possesses 209 units of blood essence.

  With 200 units of Blood Essence, Li Feng immediately felt a surge of energy and confidence. Previously, he was still considering whether or not to raise Xiao Hei to the fourth rank, but now it was clear that there was no need to think twice - it was a must.

  "Come here, Xiao Hei." Li Feng cut a large piece of the cake he had bought and placed it in the food box on the ground to comfort the three ant kings and the 300 soldier ants. Xiao Hei was already full, but upon hearing this, he quickly crawled to his side.

  "The amount of Blood Essence you currently possess can feed a 3rd-tier Ant Queen four times. Will you feed it?"

  "Yes."

  As soon as he spoke, Li Feng's hands, which were holding Xiao Hei, surged with a massive amount of heat that flowed evenly into Xiao Hei's body.

  At the same time, he could also see with his naked eye that Xiao Hei was rapidly growing in this massive hot current. The originally 30mm-long ant body was quickly expanding, and the pair of black antennae on its head were becoming more and more majestic. The black armor on its body was becoming increasingly shiny and solid.

  This time, the transfusion of blood essence took obviously longer than before, and it wasn't until several minutes had passed that it gradually came to a stop.

  However, it was a fivefold value consumption, and to raise four-tiered ant kings, Li Feng had consumed a full 125 units of blood essence this time.

  But the small black thing in front of me has grown into a huge ant, as big as 50MM, with a thumb-thick black body, it's really hard to believe that ants in this world can grow to this extent, this is no longer an organism that can be described by ants.

  Abnormal growth, everything has made Xiao Hei no longer an ordinary worker ant as before.

  "Congratulations, you have successfully bred a 4th-order ant king. This ant king has obtained the command value of summoning thousands of ants. Your 4th-order ant king has increased its loyalty to you."

  "Congratulations, you have successfully bred a 4th-order ant king. This ant king has the ability to summon ordinary ant kings with a certain probability..."

  "A thousand leadership points!" Li Feng surged with excitement, a fourth-order ant king, actually directly obtained a thousand leadership points, not four hundred, and also had a certain probability of summoning the strongest ordinary ant king in the ant colony. I'm going to be rich!

  In Li Feng's original plan, even if he raised Xiao Hei to a fourth-tier ant king, his guess was that it would only increase his overall strength by about 100 points.

  But things aren't as simple as he imagined, you know. The difference between each level of biological rank is like heaven and earth. As the rank gets higher, the abilities and benefits gained from advancing one level are naturally much greater.

  "So now I have control over an army of 1,300 ants?"

  Li Feng lifted up the small black dog which already had some weight and almost couldn't help but give it a big kiss.

  "Xiao Hei, summon all your troops for me, I want more blood essence, haha." Li Feng's heart was filled with joy.

  This snowball-like ability to expand has made him now beyond description, just after coming back, he still thought that finally having some money in hand, whether it's on Taobao or wholesale buying some insects to speed up the capture action.

  But now it seems unnecessary, with such a snowball-like rapid development speed, why bother to entrust others.

  "Hmm, hmm......" As the fourth-stage ant king Xiao Hei, at this time Yan Ran had already undergone many different changes from when it was a third-stage ant king.

  The biggest manifestation is that this guy can actually make a sound now, and the "hōu hōu" low growl is calling out to thousands of ants.

  Sure, here is the translation:

  As expected, before long, a black tide rolled in from under the door, like an urgent army maintaining order, and arrived neatly in front of Xiao Hei.

  A thousand ants stand, bowing to the ant king.

  What caught Li Feng's attention was that this time, among the shadows of the seven hundred soldier ants, there were more than thirty even larger ants.

  They have a deeper body color, a larger body shape, and are more domineering. Are they not ant kings? What is it?

  Good, very good!

  1,300 soldier ants, plus more than 30 stronger ant kings, this caught the battle strength even stronger, most importantly, there was a four-stage ant king and two three-ant kings joining in.

  Li Feng can fully believe that now, don't mention spiders or centipedes, even if it's a big bug like a praying mantis, he'll still catch it back.

  "Go ahead, eat your fill first, then mobilize all troops and capture prey for me."

  With a wave of his hand, thousands of ants sprang into action. This night was destined to be an unforgettable one for the campus's grasslands and all its forests, as at this moment, a black tide was surging forward, possessing excellent discipline, executing every command issued by Li Feng in an orderly manner.

  Unbeknownst to him, Li Feng fell asleep, but he didn't know that under the cover of night when no one was around, his army of ants were accumulating more and more prey for him.

  Until waking up the next day...

  "This is the result of a night's work by the army ants?" Fortunately, there was no one in the dormitory at this time. If someone had seen these insects piled up like small hills in one corner of the dormitory, they would have been scared out of their wits.

  So many insects piled up like this, it was Li Feng's first time seeing such a thing, probably even a large cardboard box wouldn't be enough to hold them all.

  Even the words he said last night have come true, with Xiao Hei, this fourth-order ant king, being referred to as a "desperately evil" mantis, and two of them were even caught.

  All these insects have been bitten by soldier ants and lost their mobility. Li Feng looked at this pile of insects, his scalp felt numb.

  "Little Hei, Second Hei, Third Hei, get rid of them for me." Indeed, when the bugs reached a certain level, Li Feng did have a feeling of being at a loss as to what to do with his hands.

  So he subconsciously ordered three ant kings to complete this task for him.

  For Li Feng's order, San Hei, who is loyal to Li Feng, is executing it with precision.

  "Snap..." Xiao Hei quickly pounced over and with one swift bite, ended the life of a black cicada.

  And the two blacks and three blacks are also fast, starting one after another.

  "You gain 2.2 units of Blood Essence..."

  "You gain 0.7 units of Blood Essence..."

  "You gain 1.5 units of Blood Essence..."

  The sound of the prompt kept echoing in Li Feng's mind, until now, Li Feng suddenly realized that his subconscious command had accidentally discovered that these bugs didn't need to be handled by himself, even if it was with Xiao Hei directly executing them. What does this mean?

  This means that from now on, the army of ants will no longer need to bring back prey, they only need to capture it and process it themselves, and they can also obtain blood essence.

  Goodness gracious, what a discovery!

  Li Feng thought of the greatest benefit, that is, in the future, the efficiency of collecting blood essence will probably be greatly accelerated.

  He hastily got out of bed and began a series of experiments. About an hour passed before he finally had a clear result.

  The result is that only the ant queen who has been fed by herself and is loyal to herself can replace herself, and she must be within one kilometer of the feeding creature. Otherwise, even if Xiao Hei and the others deal with the insect on their own, she will not receive any blood essence.

  Although there is a limit of one kilometer, even so, such new discoveries have greatly facilitated the speed of collecting blood essence in the future.

  "Wait, leave the larger mantis for me." Just as the last stubbornly struggling mantis was about to be finished off by three ant kings, Li Feng suddenly thought of something and hastily intervened.

  Mantis, as a bug-level, can be listed as a large bug series. It is born with a fierce temperament and has a pair of sharp mantis knives that are astonishingly sharp, making it a natural double-bladed warrior with strong combat power.

  How could I almost forget about this guy?
