Chapter 4399: There is an obstacle inside

The irrigation canals that I had seen in the Xuanwu Empire were barely novel and interesting to Zuo Feng at the time.

However, thinking about it again, the actual reason is not complicated. On the one hand, you need to have a certain understanding of the inertia of river water scouring, and on the other hand, you need to carefully identify it to see the subtle changes in the height difference on the gentle slope.

Sometimes the more complicated things are, the simpler the truth is. With a little flexibility, you may be able to use simple truths to solve complex problems.

The problem between the beast blood essence and the sparrow is of course much more complicated than a river and a field on the hillside. But sometimes the problem is like this. A small inspiration, a simple truth, or some rules that ordinary people understand, can become the key to solving the problem.

For Zuo Feng, he has built a "canal" between the beast blood essence and the sparrow's body, but after careful analysis, it seems that there is a section of this canal that is not smooth.

Since it is not smooth, Zuo Feng will find a way to open it up, just like piercing the membrane outside the beast blood essence before, and directly attack the sparrow's skin. Of course, when attacking the beast blood essence, one must be careful to grasp the degree and strength, but when attacking the sparrow, it can be simpler and rougher.

The spiritual energy was condensed into a sharp cone, directly piercing the pores. For Zuo Feng, this was the last section of the "water channel".

After doing all this, it actually only met one condition, which was still not enough to allow the beast blood essence on one side to enter the body of the sparrow.

So Zuo Feng immediately began to squeeze out the blood from the punctured part of the sparrow's body, and then let it flow into the beast blood essence.

This is very simple to say, but it requires very delicate control to do it. It is not too difficult to squeeze out blood from the punctured part of the sparrow, but it is difficult to let it flow into the beast blood essence.

Zuo Feng has some experience in the process of transferring blood between the two drops of beast blood essence before. Now he puts pressure on the beast blood essence to transfer one drop of blood to the other drop.

Now, although it was just a little bit of suction force, it could directly draw the blood in the sparrow's body into the beast blood essence.

The effect of the combination of the two bloods did not disappoint Zuo Feng. The beast blood essence did undergo amazing changes. It seemed that the inside suddenly became agitated, and the energy in the blood also began to surge.

At this point, Zuo Feng no longer needed to do anything. He only needed to fix the beast blood essence and keep it in its current position.

The beast blood essence was in a state of agitation, and the membrane was sometimes bulging and sometimes shrinking rapidly, as if it was about to break through the outer membrane at any time.

However, Zuo Feng was not worried about this at all. When he squeezed the beast blood essence just now, he was already very clear about the toughness of the membrane itself. The power at hand was not enough to completely break it.

Moreover, when he squeezed it before, the entire beast blood essence was in a completely closed state, and all the pressure was given to the membrane. Now the beast blood essence, the pierced small holes and the pores on the sparrow's skin are connected to each other, and naturally it has a channel to vent outward.

In addition, the more restless the blood is, the better it is for Zuo Feng. It's just like what Zuo Feng recalled before, the more turbulent the river at one end of the canal is, the more water will rush into the field quickly under the action of inertia.

The beast blood essence now rushes into the sparrow's body quickly while being restless. However, although the impact is great, the speed is not very fast. Even if Zuo Feng does not feel it carefully, it is difficult to feel that the blood in the beast blood essence is decreasing.

Faced with such changes, Zuo Feng seemed to understand all of a sudden why the blood in the beast blood essence could not enter the sparrow's body smoothly before.

Because the beast blood essence is too special, it is more like a natural situation for it to leave the sparrow's body, but now it is a bit against the normal law to let it flow back into the sparrow's body.

So even if the beast blood essence has a great impact and rushes towards the sparrow's body, there will still be an invisible resistance when it really enters the sparrow's body.

Fortunately, even though the speed was very slow, the beast blood essence was still continuously entering the body of the sparrow.

From the surface, there was no change in the sparrow. It was imagined that the effect would be immediate and the body would be transformed like a drastic transformation. This situation did not happen. The sparrow kept staring at Zuo Feng who was working hard with its big curious eyes.

It seemed that it was still confused now. Why did the human in front of it hurt itself just now? Although it was not too painful, the series of actions seemed to be playing with itself. In addition, the blood it was looking forward to had successfully entered its body, but why couldn't it feel anything special.

The more confused it was about the situation, the more anxious the sparrow showed. This feeling was like a hungry person who had a lot of food in front of him, but couldn't eat it.

As for Zuo Feng, although he was not anxious, his heart was already filled with confusion. The beast blood essence and the sparrow's blood, at the moment of mutual combination, showed that kind of restless reaction, and began to actively merge into the body of the sparrow.

Now that the beast blood essence has entered the body of the sparrow, the impact will only increase, and the impact and transformation on the sparrow should have been fully manifested.

‘It seems that the previous experience is not necessarily completely applicable. Facing the new environment and rules, the original principles may need to be adjusted. ’

Zuo Feng felt the changes in the beast blood essence in his palm while observing the condition of the sparrow's body, and at the same time thinking and weighing in his heart.

In theory, there should be no problem with his judgment, at least the idea is not wrong, so there may be a problem in a certain link.

Although the situation in front of Zuo Feng made him a little confused, he believed that his initial idea was correct, so there may be a problem that directly affects the result in the injection into the sparrow's body, or in the diffusion and absorption in the sparrow's body.

In Zuo Feng's opinion, although the problem is not serious, if he cannot find a corresponding solution, I am afraid that the sparrow will not be able to absorb the beast blood essence at least in a short time.

Although the problem at hand was a bit tricky, Zuo Feng was relatively calm, because from the excretion of the beast blood essence from the sparrow to the return of it to the sparrow's body, Zuo Feng was a participant in the whole process.

Facing the problem at hand, Zuo Feng thought quickly, and many possibilities that could affect the absorption of the beast blood essence also flashed through Zuo Feng's mind.

And those ideas and thoughts were quickly eliminated in his mind by Zuo Feng. There was no need to try and verify them at all. Zuo Feng was able to determine that many of them would not work.

After many possibilities were eliminated, Zuo Feng finally thought of a possibility, and it was the moment this idea flashed through his mind that he immediately grasped it firmly.

'These beast blood essences were originally in the sparrow's body. They were not absorbed. According to my speculation, they should be related to the royal bloodline.

I completely stripped out the royal bloodline, and the beast blood essence became very pure, which should be absorbed. However, the final result was still that the beast blood essence could not be absorbed.

Judging from the reaction of the sparrow, it would never reject the beast blood essence. It would be happy if it absorbed all of it at once. Since the sparrow didn't want to absorb it, there was only one possibility left, that is, there was still a barrier between the beast blood essence and the sparrow's body. '

After thinking about these possibilities again, Zuo Feng's eyes suddenly became sharp, and he finally took further action at this time.

Zuo Feng took out a green object directly from the package. Looking closely, it turned out to be something wrapped repeatedly with several leaves.

When the leaves unfolded, a ball of white liquid was directly revealed. This liquid was the Yuncao juice that Zuo Feng had found before.

At that time, part of it was swallowed directly by Zuo Feng, and a large part was collected by Zuo Feng. Fortunately, it was not a high-level medicinal material. Even if a special container was not used, there was no need to worry about the medicinal properties being dissipated in a short time.

Although the juice has not been refined, because Zuo Feng's collection method is relatively special, he collected it directly at the core of the grass stem, so the essence has been obtained by him.

At this time, there is no need to process the juice of the cloud grass in other ways. The juice itself has good quality and medicinal properties.

In addition, Zuo Feng only needs the cloud grass juice now, and does not need to mix with other medicines. A wisp of spiritual energy and telekinesis was separated and entered the container made of the leaves, as if an invisible big hand was grabbing.

The white grass juice flew directly from the leaves and quickly flew towards the sparrow. The sparrow was full of curiosity and did not understand what Zuo Feng was doing. It just felt that this tiny human seemed to be working very hard.

The grass juice wrapped in spiritual energy and telekinesis was gathered into a beam, and even turned into a sharp cone in front. Under Zuo Feng's efforts, the juice seemed to have turned into a weapon and pierced into the sparrow's skin fiercely.

Fortunately, the sparrow had great trust in Zuo Feng, so when the white medicine penetrated into the body, the sparrow had already relaxed its whole body.

If it tensed up, even if it showed vigilance and kept its body in a state of alert, then even if Zuo Feng used a real weapon, he would not be able to pierce it into the body of the sparrow.

Now that the spiritual energy and telekinesis were mixed, the front end pierced in fiercely like a spike, and the cloud grass juice followed into the body of the sparrow.

At this time, Zuo Feng noticed that there was no obstacle for the cloud grass juice to enter the body of the sparrow, and everything seemed very smooth.

From this, it can be inferred that the obstacle to the essence of beast blood did not come from the will of the sparrow, but from the effect of other existence.
